Substitute Part Grouping Explanation

Substitute parts for the MF1/4DCT52R1503F are qualified based on the following criteria:

Direct Electrical Equivalents (Same Resistance Value):

• MFR-25FBF52-150K (YAGEO) matches all critical electrical parameters: 150 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical dimensions are within acceptable tolerance (0.094" Dia x 0.248" L vs. 0.091" Dia x 0.248" L). Both components are ROHS3 compliant and suitable for equivalent circuit performance.

Non-Equivalent Parts Listed:

• MFR-25FRF52-1K5 (YAGEO) is listed in the original part's substitute field but has a different resistance value of 1.5 kOhms. This part does not qualify as an electrical equivalent and should not be used as a direct substitute for the MF1/4DCT52R1503F.

Parameter Comparison

Engineering Selection Recommendations

The MFR-25FBF52-150K from YAGEO is the qualified substitute for the MF1/4DCT52R1503F. Both components share identical electrical specifications and are ROHS3 compliant. The minor dimensional variance (0.003" difference in diameter) is within standard PCB layout tolerances for axial through-hole components and does not affect mechanical fit or electrical performance.

Selection between the original KOA part and the YAGEO substitute should be based on availability, lead time, and packaging format requirements. The KOA part is supplied in Cut Tape (CT) packaging with 692 units in stock, while the YAGEO equivalent is available in Bulk packaging with 7592 units in stock.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-150K be used as a direct replacement for MF1/4DCT52R1503F?

A: Yes. Both components have identical resistance (150 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimensions are compatible with standard PCB through-hole layouts.

Q: What is the difference between the KOA and YAGEO versions?

A: The primary differences are manufacturer and packaging format. The KOA part (MF1/4DCT52R1503F) is supplied in Cut Tape packaging, while the YAGEO equivalent (MFR-25FBF52-150K) is supplied in Bulk packaging. Electrical performance and compliance certifications are equivalent.

Q: Is MFR-25FRF52-1K5 a suitable substitute?

A: No. MFR-25FRF52-1K5 has a resistance value of 1.5 kOhms, which differs from the required 150 kOhms. This part is not electrically equivalent and cannot be used as a substitute.

Q: Are there any compliance or certification differences?

A: Both the original part and the qualified substitute are ROHS3 compliant and REACH unaffected. The original KOA part includes AEC-Q200 automotive qualification, which is not specified for the YAGEO substitute. Verify AEC-Q200 requirement for your specific application before substitution.

Q: Will the slight dimensional difference affect PCB assembly?

A: No. The 0.003" diameter difference (0.091" vs. 0.094") is within standard manufacturing tolerances for axial through-hole resistors and does not affect hole sizing, lead spacing, or mechanical fit on standard PCB layouts.
