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

The identified substitute part MFR-25FBF52-1K47 meets all electrical and mechanical requirements for direct substitution. Physical dimensions may vary within the axial package category; however, both parts maintain compatibility with standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/4DCT52R1471F and MFR-25FBF52-1K47 are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts may be based on:

• Availability: MFR-25FBF52-1K47 has higher inventory (2204 units) compared to MFS1/4DCT52R1471F (924 units)
• Packaging format: MFS1/4DCT52R1471F is supplied in Cut Tape; MFR-25FBF52-1K47 is supplied in Bulk
• Physical dimensions: MFS1/4DCT52R1471F has a smaller profile (1.70mm x 3.20mm) versus MFR-25FBF52-1K47 (2.40mm x 6.30mm)
• Automotive qualification: MFS1/4DCT52R1471F carries AEC-Q200 certification; MFR-25FBF52-1K47 does not specify automotive qualification

For applications requiring automotive-grade components, MFS1/4DCT52R1471F is the specified choice. For general industrial applications where automotive qualification is not required, MFR-25FBF52-1K47 provides equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-1K47 be used in place of MFS1/4DCT52R1471F in automotive applications?

A: MFR-25FBF52-1K47 meets all electrical and mechanical specifications for direct substitution. However, MFS1/4DCT52R1471F carries AEC-Q200 automotive qualification while MFR-25FBF52-1K47 does not specify this certification. Application requirements determine whether automotive qualification is mandatory.

Q: What are the physical dimension differences between these parts?

A: MFS1/4DCT52R1471F measures 0.067" diameter x 0.126" length (1.70mm x 3.20mm). MFR-25FBF52-1K47 measures 0.094" diameter x 0.248" length (2.40mm x 6.30mm). Both are axial through-hole packages compatible with standard PCB layouts, though space-constrained designs may require the smaller MFS1/4DCT52R1471F.

Q: Are both parts RoHS compliant?

A: Yes, both MFS1/4DCT52R1471F and MFR-25FBF52-1K47 are ROHS3 compliant and REACH unaffected.

Q: What is the difference in packaging between these parts?

A: MFS1/4DCT52R1471F is supplied in Cut Tape packaging, suitable for automated assembly. MFR-25FBF52-1K47 is supplied in Bulk packaging, typically used for manual assembly or reel conversion.

Q: Do these resistors have identical electrical performance?

A: Yes, both parts share identical resistance (1.47 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).
