Substitute Part Grouping Explanation

Substitution eligibility for the MFS1/4DCT52R10R0F is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The MFR-25FBF52-10R manufactured by YAGEO meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/4DCT52R10R0F and MFR-25FBF52-10R are active production components with identical electrical specifications and regulatory compliance status. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Cut Tape versus Bulk)
• Supplier inventory levels and procurement timelines
• Physical dimensions compatibility within PCB layout constraints

The MFR-25FBF52-10R from YAGEO provides 35353 units in current stock, offering enhanced availability compared to the KOA Speer alternative. Both components satisfy ROHS3 and REACH compliance requirements for automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-10R be used as a direct replacement for MFS1/4DCT52R10R0F?

A: Yes. Both components share identical electrical parameters (10 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C operating range) and are manufactured as metal film axial resistors with equivalent regulatory compliance.

Q: Are there physical dimension differences between these parts?

A: Yes. The MFS1/4DCT52R10R0F measures 0.067" diameter × 0.126" length (1.70mm × 3.20mm), while the MFR-25FBF52-10R measures 0.094" diameter × 0.248" length (2.40mm × 6.30mm). PCB layout and component spacing must accommodate the larger YAGEO part dimensions.

Q: Do both parts meet automotive qualification standards?

A: The MFS1/4DCT52R10R0F carries AEC-Q200 automotive qualification. The MFR-25FBF52-10R does not list automotive qualification features in the provided specifications. Automotive application requirements should be verified against design specifications before substitution.

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

A: Cut Tape packaging provides components on continuous tape suitable for automated pick-and-place assembly. Bulk packaging provides loose components for manual handling or alternative assembly processes. Packaging selection depends on manufacturing equipment and assembly methodology.

Q: Are both parts RoHS compliant?

A: Yes. Both MFS1/4DCT52R10R0F and MFR-25FBF52-10R are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for EU and global markets.
