Substitute Part Grouping Explanation

Substitution eligibility for the MFS1/4DCT52R4753F is determined by strict equivalence across the following critical parameters:

• Resistance value: 475 kOhms (exact match required)
• Tolerance: ±1% (ensures circuit performance specifications)
• Power rating: 0.25W / 1/4W (thermal and current handling capability)
• Composition: Metal film (electrical stability and temperature coefficient characteristics)
• Package: Axial through-hole (mechanical fit and soldering compatibility)
• Temperature coefficient: ±100ppm/°C (frequency and temperature stability)
• Operating temperature range: -55°C to +155°C (environmental performance envelope)
• Compliance: ROHS3 and REACH standards (regulatory and supply chain requirements)

The substitute part MFR-25FBF52-475K from YAGEO meets all these criteria and is therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/4DCT52R4753F and MFR-25FBF52-475K are active production components with equivalent electrical specifications and full compliance with ROHS3 and REACH regulations. Selection between these parts may be based on:

• Availability and lead time from respective suppliers
• Packaging format preference (Cut Tape vs. Bulk)
• Established supply chain relationships
• Physical dimensions if space constraints exist (MFS: 1.70mm Dia × 3.20mm L; MFR: 2.40mm Dia × 6.30mm L)

Both components are suitable for automotive and industrial applications requiring stable metal film resistor performance across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-475K be used as a direct replacement for MFS1/4DCT52R4753F?

A: Yes. Both parts share identical electrical specifications (475 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to +155°C) and axial through-hole package configuration. They are electrically and mechanically interchangeable.

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

A: Cut Tape (CT) packaging provides individual component strips suitable for automated pick-and-place assembly. Bulk packaging is typically used for manual assembly or reel-based automated processes. Both packaging formats contain identical components.

Q: Are there dimensional differences between these parts?

A: Yes. The MFS1/4DCT52R4753F measures 1.70mm diameter × 3.20mm length, while the MFR-25FBF52-475K measures 2.40mm diameter × 6.30mm length. Both fit standard through-hole PCB layouts, but physical space constraints may influence selection.

Q: Do both parts meet automotive qualification standards?

A: The MFS1/4DCT52R4753F carries AEC-Q200 automotive qualification. The MFR-25FBF52-475K does not list automotive qualification in the provided specifications. Verify automotive requirements for your specific application.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MFS1/4DCT52R4753F and MFR-25FBF52-475K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
