Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFR-25FRE52-100R is determined by the following critical parameters:

• Resistance value: 100 Ohms (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 (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Physical dimensions: 0.094" Dia x 0.248" L (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The MFR-25FBF52-100R qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts maintain the same component specifications and are suitable for identical circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MFR-25FRE52-100R and MFR-25FBF52-100R are Active status components manufactured by YAGEO within the MFR series. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

The MFR-25FBF52-100R serves as a functional equivalent for applications where Bulk packaging is acceptable. The primary technical distinction is the temperature coefficient specification: the main part specifies ±50ppm/°C while the substitute specifies ±100ppm/°C. This difference is within acceptable tolerances for standard circuit applications operating within the -55°C to 155°C range.

Selection between these parts should be based on procurement requirements, packaging format compatibility with assembly processes, and inventory availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-100R replace MFR-25FRE52-100R in production assembly?

A: Yes. Both parts are electrically and mechanically identical 100 Ohms ±1% metal film axial resistors with 0.25W power rating. The difference is packaging format: Tape & Reel versus Bulk. Compatibility depends on whether your assembly equipment can process Bulk packaging.

Q: What is the significance of the temperature coefficient difference (±50ppm/°C vs ±100ppm/°C)?

A: The temperature coefficient indicates resistance value drift over temperature. The main part (±50ppm/°C) exhibits lower drift than the substitute (±100ppm/°C). For most standard applications, both specifications are acceptable. Applications requiring precision temperature stability should specify the main part.

Q: Are both parts RoHS compliant?

A: Yes. Both MFR-25FRE52-100R and MFR-25FBF52-100R are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards.

Q: What packaging format should I select?

A: Tape & Reel (TR) packaging is standard for automated assembly lines. Bulk packaging is suitable for manual assembly or applications where reel compatibility is not required. Select based on your assembly process requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.094" diameter by 0.248" length (2.40mm x 6.30mm) and are axial configuration with 2 terminations. They are mechanically interchangeable on PCBs.
