LF14000NN Cross Reference to Donaldson, Napa, Baldwin, Wix, and More

Looking up cross-reference data for filters can help save lots of time and money, especially considering how pricey some of these OEM parts can be, and how long they can take to deliver. And whether you buy them, parts will always need replacing, so having a backup is incredibly helpful.

In Brand Xlookup, filters almost always return the LF14000NN first.

This guide will provide you with cross-reference data for the LF14000NN filter and will validate that data against the filter banks within the Donaldson, Napa, Baldwin, Wix, etc., and many others.

LF14000NN

Fleetguard / Cummins Filtration’s NanoNet® + StrataPore® combination full-flow (spin-on) lube oil filter is designed for the long oil drain times and low restriction requirements of high-horsepower Cummins engines.

Commonly used in engines such as the Cummins ISX/X15, common cross-references include: Donaldson P559000 / P550949, Baldwin BD50000, WIX WL10107 (/57746 series), NAPA 400107 / 7746, etc.

lf14000nn cross reference to Donaldson？

The Fleetguard LF14000NN is considered a full-flow oil filter meant for Cummins ISX/X15 series engines. For users looking for an alternative brand, the Donaldson P559000 is one of the most frequently mentioned comparison models.

The Donaldson Cummins ISX/X15 documents have the P559000 along with other full-flow oil filters. They even have promotional comparisons with the LF14000NN, containing, among other things, holding capacity/lifespan advantages. This doesn’t mean, of course, a replacement under all operating conditions is guaranteed. However, the Donaldson P559000 is considered, in most cross-tabulations, an alternative.

Before making the switch from LF14000NN to Donaldson P559000, check the seal OD, thread size and configuration, overall height, filter media/micron rating, as well as BPV/bypass. If all these parameters are consistent, perform 1-2 oil change cycles on a non-critical vehicle. Alternatively, test one vehicle and check oil pressure and engine condition.

Parameter	Fleetguard LF14000NN	Donaldson P559000	Notes
Seal Outer Diameter	≈93 mm	≈93 mm	Must match exactly, otherwise oil leakage may occur
Thread Specification	1-16 UN	1-16 UN	Must match exactly
Filter Total Height	≈300 mm	≈300 mm	Large height differences may affect installation space
Filtration Media	NanoNet media (high efficiency)	Synteq media	Recommend verifying micron rating
Bypass Valve Setting	20–24 psi	20–24 psi	Bypass pressure must be identical

lf14000nn cross reference to Napa？   

NAPA’s 400107/7746 series oils do correlate to LF14000NN in distribution and cross tabulation (these models can be verified in the official NAPA catalog, and NAPA occasionally produces/supplies oils to WIX). The most frequently mentioned are the Napa 400107 and 7746/7746XD.  

NAPA routinely ships under its own label (NapaGold), but in some cases has supplied oils under the WIX trademark brand, so this is something to note on the purchase (quality-minded fleets may buy directly from the original manufacturer or a designated brand). If you use prolonged oil drain intervals, be sure to verify the micron rating.

lf14000nn cross reference to Baldwin？

Indeed, Baldwin’s Quick Cross-Reference does place the BD50000 with the LF14000NN, Donaldson P559000, and WIX WL10107 (Baldwin’s Quick Cross-Reference PDF does confirm linkage to Fleetguard LF14000NN). Baldwin’s M95 x 2.5 product page also purports to include specific threads, outer diameter, and height (for field verification).  

Baldwin is commonly deployed by fleets as an anti-containment copy (some fleets like its “dual-flow” or high efficiency versions). Likewise, replace the core size before anything else, and save an oil sample to log oil pressure and temperature before the first oil change.

lf14000nn cross reference to Wix?

In the common replacement catalog for Fleetguard LF14000NN, WIX WL10107 and WIX 57746 / 57746XD are the most recognized comparison models

WIX Model	Typical Application	Notes
WL10107	Cummins ISX/X15 full-flow oil filter	WIX official HD series, commonly used in commercial trucks
57746 / 57746XD	Cummins ISX/X15 full-flow oil filter	XD stands for “Extended Drain” design for longer oil change intervals, with higher dirt-holding capacity

WIX has a wide channel and dealer network, making purchases easy; however, be sure to check whether the model is the “HD / XD / XD-synthetic” version (performance varies slightly between versions).

Parameter	Fleetguard LF14000NN	WIX WL10107 / 57746XD	Notes
Outer Diameter (OD)	≈93 mm	≈93 mm	Must match exactly to ensure proper sealing
Thread Specification	1-16 UN	1-16 UN	Must match
Height	≈300 mm	≈300 mm	Check if engine compartment space is sufficient
Bypass Valve Setting	20–24 psi	20–24 psi	Affects cold-start oil pressure
Filtration Media	NanoNet (high efficiency)	Cellulose / Synthetic (depends on version)	XD version uses synthetic media, suitable for extended oil change intervals

• The WIX WL10107 and WIX 57746/57746XD are mainstream crossover models for the LF14000NN, sharing essentially identical dimensions, threads, and bypass valve pressure ratings.
• The XD/XD-Synthetic versions are suitable for extended oil drain intervals, but be sure to verify the model and filter media specifications when purchasing to ensure compatibility with your fleet’s maintenance strategy.

Performance Differences and the Risks of “Direct Substitution” (Why You Can’t Just Look at the Crosstab)

Filter media and efficiency: Self-claimed ‘micron ratings’ and created ‘efficiencies’ aside, just because a manufacturer’s filter media is just as claimed, its internal structures, such as layers, fiber or paper bases, and bonding processes, result in different clogging curves, and vary in load capacity. In Donaldson’s literature, they make note that their filter possesses greater dirt holding capacity than LF14000NN (factory comparative data Reporting). Donaldson Filtration Solutions

Bypass valve for the differential pressure behavior reports: Different brands report having different bypass opening pressures in the higher contamination/below temperature start-up range, resulting in lubricant filtration being less than the desired level for a short period of time.

Sealing Surface and Gasket: a difference of 1-2mm in the diameter of the Gasket results in Oil Leak and Installation Failure.

Different batches and different regions of OEM Manufacturing (OEM/OEM branding) can result in slight variations of materials and or dimensions for the same model.

Some warranties or agreements supplied for services by the OEM may mandate the genuine or approved refurbished parts to be used.

Procurement and service recommendations (avoid pitfalls)

This document summarizes our preferred buying SNP: Original Cummins/Fleetguard distributors and Baldwin dealers, and associated NAPA and heavy-duty parts distributors like FleetPride. They can provide certified data sheets and can trace the batch. Cummins stores +2, NAPA Auto Parts +2  

Caution low price / wrong channels: in most cases, a very low price means OEM, repackaging, missing batch numbers and data sheets… counterfeits. warranty and longevity.  

Supplier verification: Ask for the individual OEM number, like Cummins 4367100, BAT, and associated documents: MSDS/Technical Data Sheet. If they don’t have them, don’t hurry with mass replacements.  

Service/Replacement History: to reduce the time needed for problem-solving patches downstream, log the oil sample, engine ID + mileage, part number, batch, and the corresponding MSDS/Technical Data.
