MFR-25FRF52-182K Equivalent & Substitute Parts

Part Overview

The MFR-25FRF52-182K is a 182 kOhms ±1% 0.25W through-hole resistor manufactured by YAGEO in axial metal film composition. This component is actively produced and widely used in general-purpose electronic applications requiring precision resistive elements with tight tolerance specifications. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility are maintained within the allowed parameter ranges for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFR-25FRF52-182K is determined by the following criteria:

• Resistance value must be 182 kOhms
• Tolerance must be ±1% or tighter
• Composition must be metal film
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C ~ 155°C
• Package must be axial through-hole
• RoHS3 compliance required

The SFR2500001823FR500 meets all substitution criteria. While its power rating is 0.4W (higher than the 0.25W main part), this represents an upgrade in capability and does not restrict its use in applications designed for the 0.25W specification.

Parameter Comparison

Engineering Selection Recommendations

Both the MFR-25FRF52-182K and SFR2500001823FR500 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The MFR-25FRF52-182K maintains the original 0.25W power specification and smaller physical dimensions (2.40mm diameter).

The SFR2500001823FR500 provides increased power dissipation capability at 0.4W with marginally larger dimensions (2.50mm diameter). This substitute is suitable for applications where the higher power rating provides additional thermal margin or where component availability favors the Vishay Beyschlag/Draloric/BC Components source.

Both parts maintain identical electrical performance in resistance value, tolerance, temperature coefficient, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the SFR2500001823FR500 replace the MFR-25FRF52-182K in all applications?

A: Yes, within the electrical and thermal design constraints of the application. The substitute part provides equivalent resistance, tolerance, and temperature characteristics. The higher 0.4W power rating does not restrict its use in 0.25W-rated circuits. Physical dimensions differ slightly (2.50mm vs 2.40mm diameter), which may affect PCB layout in space-constrained designs.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching resistance value (182 kOhms), tolerance (±1%), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package type (axial). Compliance certifications (ROHS3, REACH) must also align.

Q: Are there dimensional compatibility concerns?

A: The substitute part is slightly larger (0.098" diameter vs 0.094", 0.256" length vs 0.248"). Verify PCB hole spacing and component clearance in confined layouts before substitution.

Q: Do both parts have equivalent long-term reliability?

A: Both parts are active products from established manufacturers with identical temperature coefficients and operating ranges. Reliability depends on application-specific stress conditions and thermal management.
