Substitute Part Grouping Explanation

Substitute parts for the MF1/4DCT52R2002F are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents (MF1/4DCT52A2002F, MF1/4DCVTR2002F): These parts share identical electrical specifications with the main part—20 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are manufactured by KOA Speer Electronics, Inc., carry AEC-Q200 automotive qualification, and maintain ROHS3 compliance. Physical dimensions are identical (0.091" Dia x 0.248" L / 2.30mm x 6.30mm). These parts are direct functional replacements.

Similar Equivalents (MFR-25FBF52-20K, MFR-25FRF52-20K): These YAGEO-manufactured parts match all critical electrical parameters—20 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both maintain ROHS3 compliance. Physical dimensions show a minor variation in diameter (0.094" Dia x 0.248" L / 2.40mm x 6.30mm versus 0.091" Dia). These parts are functionally equivalent with negligible dimensional difference in the radial direction.

Substitution is determined by matching resistance value, tolerance, power rating, composition type, temperature coefficient, operating temperature range, and compliance certifications. Packaging format (Cut Tape versus Bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: Select MF1/4DCT52A2002F or MF1/4DCVTR2002F. Both parts are manufactured by KOA Speer Electronics and carry explicit AEC-Q200 automotive qualification. These parts maintain identical electrical and mechanical specifications to the primary part MF1/4DCT52R2002F and are suitable for direct substitution in automotive-grade circuit designs.

For General Industrial Applications: MFR-25FBF52-20K and MFR-25FRF52-20K from YAGEO are functionally equivalent alternatives. These parts match all critical electrical parameters and maintain ROHS3 compliance. The minor radial dimension increase (0.094" versus 0.091" diameter) is negligible for standard PCB through-hole layouts. Selection between these YAGEO options depends on packaging requirements: MFR-25FRF52-20K is supplied in Cut Tape format with significantly higher inventory (45068 units), while MFR-25FBF52-20K is supplied in Bulk format.

Inventory Considerations: MFR-25FRF52-20K offers the highest stock availability at 45068 units. MFR-25FBF52-20K provides 17244 units in bulk packaging. KOA Speer parts (MF1/4DCT52A2002F with 5733 units and MF1/4DCVTR2002F with 3642 units) are available for applications requiring automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-20K or MFR-25FRF52-20K be used as direct replacements for MF1/4DCT52R2002F in automotive applications?

A: The YAGEO MFR series parts match all electrical specifications (20 kOhms, ±1%, 0.25W, metal film, ±100ppm/°C, -55°C to 155°C) and maintain ROHS3 compliance. However, they do not carry explicit AEC-Q200 automotive qualification. Use in automotive applications requires design review and validation against specific application requirements.

Q: What is the difference between MF1/4DCT52A2002F and MF1/4DCVTR2002F?

A: Both parts are manufactured by KOA Speer Electronics with identical electrical and mechanical specifications, AEC-Q200 qualification, and ROHS3 compliance. The difference lies in internal construction or manufacturing process designation. Both are direct equivalents to MF1/4DCT52R2002F.

Q: Does the 0.003" (0.10mm) diameter difference between KOA and YAGEO parts affect PCB compatibility?

A: No. The diameter difference (0.091" versus 0.094") is within standard PCB through-hole tolerances. Both part families use identical axial lead spacing (0.248" length) and are compatible with standard through-hole PCB layouts.

Q: Which substitute part should be selected for highest availability?

A: MFR-25FRF52-20K (YAGEO) offers the highest inventory at 45068 units in Cut Tape packaging. This part is suitable for non-automotive applications requiring standard metal film resistor specifications.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All five parts (MF1/4DCT52R2002F, MF1/4DCT52A2002F, MF1/4DCVTR2002F, MFR-25FBF52-20K, and MFR-25FRF52-20K) are ROHS3 compliant and REACH unaffected.
