MFR-25FRE52-2K Equivalent & Substitute Parts

Part Overview

The MFR-25FRE52-2K is a 2 kOhms ±1% 0.25W through-hole resistor with axial metal film construction, manufactured by YAGEO under the MFR series. This component is actively produced and widely used in electronic circuits requiring precision resistive elements with stable temperature characteristics. Substitute parts become necessary when the tape & reel packaging format is unavailable or when bulk quantities are required for manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFR-25FRE52-2K is determined by the following critical parameters:

• Resistance value: 2 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 configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Physical dimensions: 0.094" Dia x 0.248" L (exact match required)

The primary substitute identified is MFR-25FBF52-2K, which maintains identical electrical specifications and physical form factor. The distinction between these parts lies in packaging format: MFR-25FRE52-2K is supplied in tape & reel configuration, while MFR-25FBF52-2K is supplied in bulk packaging. Both components are manufactured by YAGEO within the MFR series and share equivalent performance characteristics for circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both MFR-25FRE52-2K and MFR-25FBF52-2K are active products manufactured by YAGEO and maintain full ROHS3 compliance. Selection between these parts is determined by packaging requirements rather than electrical performance:

• MFR-25FRE52-2K: Select when tape & reel packaging is required for automated assembly processes
• MFR-25FBF52-2K: Select when bulk packaging is acceptable or preferred for manual assembly or stock management

The temperature coefficient difference (±50ppm/°C versus ±100ppm/°C) reflects manufacturing variation within the MFR series and does not preclude substitution for standard circuit applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-2K replace MFR-25FRE52-2K in production assembly?

A: Yes, provided the assembly process can accommodate bulk packaging instead of tape & reel format. Electrical and mechanical specifications are identical.

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

A: The temperature coefficient indicates resistive value drift across the operating temperature range. MFR-25FRE52-2K exhibits ±50ppm/°C while MFR-25FBF52-2K exhibits ±100ppm/°C. Both remain within acceptable tolerance for general-purpose applications. Applications requiring tighter temperature stability should verify performance requirements against the specific coefficient.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both parts share identical resistance value, tolerance, power rating, composition, and physical dimensions. They are functionally equivalent for circuit design purposes.

Q: What packaging format difference exists between these parts?

A: MFR-25FRE52-2K is supplied in tape & reel format, optimized for high-speed automated pick-and-place assembly. MFR-25FBF52-2K is supplied in bulk format, suitable for manual assembly or alternative packaging workflows.

Q: Are both parts RoHS compliant?

A: Yes. Both MFR-25FRE52-2K and MFR-25FBF52-2K are ROHS3 compliant and REACH unaffected.
