Substitute Part Grouping Explanation

Substitution eligibility for the MFS1/4DCT52R1004F is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package configuration: Axial through-hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant

The MFR-25FBF52-1M from YAGEO meets all specified electrical and mechanical parameters, qualifying it as a direct substitute. Physical dimensions vary between manufacturers but remain within acceptable tolerances for axial component mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/4DCT52R1004F and MFR-25FBF52-1M are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging format requirements: MFS1/4DCT52R1004F is supplied in Cut Tape (CT) format; MFR-25FBF52-1M is supplied in Bulk format
• Physical space constraints: The KOA Speer component has a smaller axial diameter (0.067" vs 0.094") and shorter length (0.126" vs 0.248")
• Inventory availability: MFR-25FBF52-1M has higher stock levels (11624 units vs 6030 units)
• Automotive qualification: MFS1/4DCT52R1004F carries explicit AEC-Q200 designation

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-1M replace MFS1/4DCT52R1004F in automotive applications?

A: Both components meet the same electrical specifications (1 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). However, MFS1/4DCT52R1004F carries explicit AEC-Q200 automotive qualification. MFR-25FBF52-1M should be evaluated against your specific automotive qualification requirements before substitution.

Q: What are the physical dimension differences?

A: MFS1/4DCT52R1004F measures 0.067" diameter × 0.126" length. MFR-25FBF52-1M measures 0.094" diameter × 0.248" length. The YAGEO component is larger in both dimensions. Verify PCB layout and mechanical clearances before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both MFS1/4DCT52R1004F and MFR-25FBF52-1M are ROHS3 compliant and REACH unaffected.

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

A: MFS1/4DCT52R1004F is supplied in Cut Tape (CT) format, suitable for automated pick-and-place assembly. MFR-25FBF52-1M is supplied in Bulk format, typically used for manual assembly or reel-based automated processes. Packaging selection depends on your assembly method and volume requirements.

Q: Can I use these parts interchangeably in high-temperature applications?

A: Both components operate across the same temperature range (-55°C to 155°C) with identical temperature coefficients (±100ppm/°C). They are electrically interchangeable within this range.
