MFR-25FRF52-2K21 Equivalent & Substitute Parts

Part Overview

The MFR-25FRF52-2K21 is a 2.21 kOhms ±1% metal film axial through-hole resistor rated at 0.25W (1/4W) manufactured by YAGEO. This component is currently in active production status with 983 pieces available in new original stock. The part is ROHS3 compliant and suitable for general-purpose resistive applications requiring standard tolerance and moderate power dissipation in compact axial packaging.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative specifications that offer improved performance characteristics or enhanced availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFR-25FRF52-2K21 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 2.21 kOhms (exact match required)
• Tolerance: ±1% or better (tighter tolerance acceptable)
• Composition: Metal film (maintains electrical characteristics)
• Package type: Axial (ensures mechanical compatibility)
• Operating temperature range: Must encompass -55°C ~ 155°C minimum
• Number of terminations: 2 (standard through-hole configuration)

Flexible Parameters (Substitution Permitted):

• Power rating: May be equal to or greater than 0.25W
• Temperature coefficient: May be equal to or better (lower ppm/°C acceptable)
• Manufacturer: Different manufacturers acceptable if all mandatory criteria met

The three substitute parts listed below satisfy all mandatory matching criteria and are therefore electrically and mechanically compatible with the MFR-25FRF52-2K21.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and full regulatory compliance. Selection between the MFR-25FRF52-2K21 and its substitutes depends on application-specific requirements:

MRS25000C2211FRP00 offers increased power dissipation capacity (0.6W) and improved temperature stability (±50ppm/°C). This substitute is suitable for applications where thermal margin or enhanced frequency stability is beneficial.

SFR2500002211FR500 provides moderate power rating increase (0.4W) while maintaining identical temperature coefficient performance (±100ppm/°C). This substitute balances thermal headroom with cost-effectiveness.

YR1B2K21CC delivers superior tolerance specification (±0.1% versus ±1%) and exceptional temperature coefficient performance (±15ppm/°C). This substitute is appropriate for precision measurement circuits or applications requiring tight resistance stability across temperature variations. Extended operating temperature range (-65°C minimum) provides additional environmental margin.

All substitutes are manufactured by established component suppliers with equivalent regulatory certifications and are available in significantly higher stock quantities.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C2211FRP00 be used as a direct replacement for MFR-25FRF52-2K21?

A: Yes. Both components share identical resistance value (2.21 kOhms), tolerance (±1%), axial package configuration, and operating temperature range. The higher power rating (0.6W versus 0.25W) and improved temperature coefficient (±50ppm/°C) represent performance enhancements with no compatibility issues.

Q: What is the primary difference between SFR2500002211FR500 and MRS25000C2211FRP00?

A: Both are Vishay products with identical resistance and tolerance specifications. SFR2500002211FR500 has a 0.4W power rating (versus 0.6W) and maintains the original ±100ppm/°C temperature coefficient. Selection depends on thermal requirements and cost considerations.

Q: Is YR1B2K21CC suitable for general-purpose applications?

A: Yes. YR1B2K21CC meets all mandatory compatibility criteria and is suitable for any application accepting the MFR-25FRF52-2K21. The tighter tolerance (±0.1%) and superior temperature coefficient (±15ppm/°C) provide additional performance margin without introducing compatibility constraints.

Q: Do all substitute parts maintain the same physical dimensions?

A: All substitute parts use axial package configuration with similar dimensions. MFR-25FRF52-2K21 measures 0.094" Dia x 0.248" L. Substitute parts measure 0.098" Dia x 0.256" L (MRS25000C2211FRP00 and SFR2500002211FR500) or 0.091" Dia x 0.248" L (YR1B2K21CC). These minor variations are within standard PCB layout tolerances for axial component placement.

Q: Are all parts RoHS compliant?

A: Yes. MFR-25FRF52-2K21, MRS25000C2211FRP00, SFR2500002211FR500, and YR1B2K21CC are all RoHS compliant, meeting ROHS3 or equivalent standards.

Q: Which substitute offers the best long-term stability?

A: YR1B2K21CC provides the best resistance stability with ±15ppm/°C temperature coefficient and ±0.1% tolerance specification. This part is recommended for applications requiring minimal resistance drift across operating temperature ranges.
