Substitute Part Grouping Explanation

Substitute parts for the MF1/4DCT52R2003F are identified based on strict equivalence of the following critical parameters:

• Resistance value: 200 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial Through-Hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant

Two substitute parts meet these criteria. The MF1/4DCVTR2003F is a parametric equivalent from the same manufacturer (KOA Speer Electronics, Inc.) within the MF series, differing only in packaging format (Cut Tape). The MFR-25FBF52-200K is a similar part from YAGEO with identical electrical specifications and axial package configuration, with a minor dimensional variation in diameter (0.094" vs 0.091").

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full ROHS3 compliance. The MF1/4DCVTR2003F provides direct parametric equivalence with identical dimensions and is sourced from the same manufacturer, making it the primary substitute option. The MFR-25FBF52-200K from YAGEO offers equivalent electrical performance with a minor diameter increase (0.094" vs 0.091"), which remains within typical PCB pad tolerances for axial through-hole components. Selection between these substitutes should be based on availability, lead time requirements, and packaging format preferences (Cut Tape vs Bulk).

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCVTR2003F be used as a direct replacement for MF1/4DCT52R2003F?

A: Yes. Both parts are identical in all electrical parameters, temperature characteristics, and physical dimensions. The only difference is packaging format (Cut Tape vs standard tape configuration).

Q: Is the MFR-25FBF52-200K compatible with the same PCB layout?

A: The MFR-25FBF52-200K has a slightly larger diameter (0.094" vs 0.091"). This minor dimensional difference is typically accommodated by standard PCB pad designs for axial through-hole resistors. Verify pad spacing in your specific design if tight component density is a constraint.

Q: Do all substitute parts meet automotive qualification requirements?

A: The MF1/4DCVTR2003F carries the same AEC-Q200 automotive qualification as the main part. The MFR-25FBF52-200K does not list automotive qualification features in the provided specifications.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape packaging provides individual component strips suitable for automated pick-and-place assembly. Bulk packaging is typically used for manual assembly or high-volume reel formats. Both formats contain the same component.

Q: Are there any temperature or tolerance differences between these parts?

A: No. All three parts share identical temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and tolerance (±1%).
