MFR-25FRE52-15K Equivalent & Substitute Parts

Part Overview

The MFR-25FRE52-15K is a 15 kOhms ±1% 0.25W through-hole resistor with axial metal film construction, manufactured by YAGEO in the MFR series. This component is actively produced and widely used in general-purpose electronic applications requiring precision resistive elements. Substitute parts may be required due to packaging format availability, inventory constraints, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFR-25FRE52-15K is determined by the following critical parameters:

• Resistance value: 15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.094" Dia x 0.248" L (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Terminations: 2 (exact match required)

The MFR-25FBF52-15K qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Bulk format. Both components are manufactured by YAGEO within the MFR series and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MFR-25FRE52-15K and MFR-25FBF52-15K are active products manufactured by YAGEO and maintain full compliance with ROHS3 and REACH regulations. Selection between these components should be based on packaging requirements:

• MFR-25FRE52-15K: Select when Tape & Reel packaging is required for automated assembly processes or when component handling and storage specifications mandate this format.
• MFR-25FBF52-15K: Select when Bulk packaging is acceptable or preferred for manual assembly, prototyping, or applications where packaging format does not impose constraints.

The temperature coefficient difference (±50ppm/°C versus ±100ppm/°C) reflects manufacturing process variations within the MFR series and does not affect functional interchangeability for standard applications operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-15K replace MFR-25FRE52-15K in production assembly?

A: Yes, provided the assembly process can accommodate Bulk packaging format. The electrical and mechanical specifications are identical, and both components are ROHS3 compliant active products.

Q: What is the significance of the temperature coefficient difference?

A: The temperature coefficient indicates the resistor's resistance change per degree Celsius. The MFR-25FRE52-15K has ±50ppm/°C while the MFR-25FBF52-15K has ±100ppm/°C. Both values are within acceptable ranges for general-purpose applications and do not affect interchangeability for circuits operating within the -55°C ~ 155°C range.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.094" Dia x 0.248" L (2.40mm x 6.30mm) and are axial package type, ensuring mechanical compatibility in PCB layouts and through-hole assembly.

Q: What packaging format difference exists between these substitutes?

A: MFR-25FRE52-15K is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. MFR-25FBF52-15K is supplied in Bulk format, suitable for manual assembly or applications without automated handling requirements.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both MFR-25FRE52-15K and MFR-25FBF52-15K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
