Substitute Part Grouping Explanation

Substitution eligibility for the MF0207FRE52-121R is determined by strict equivalence across the following parameters:

• Resistance value: 121 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Package configuration: Axial through hole (exact match required)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The MRS25000C1210FRP00 manufactured by Vishay Beyschlag/Draloric/BC Components meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the MF0207FRE52-121R and MRS25000C1210FRP00 are active production components with identical electrical and mechanical specifications. Selection between these parts is based on:

• Procurement availability and lead time requirements
• Supplier inventory status and supply chain preferences
• Packaging format: MF0207FRE52-121R is supplied in Tape & Reel (TR) format; MRS25000C1210FRP00 is supplied in Cut Tape (CT) format
• Regulatory compliance: Both components satisfy ROHS3 and REACH requirements for applications requiring environmental compliance

Frequently Asked Questions (FAQ)

Q: Can MRS25000C1210FRP00 be used as a direct replacement for MF0207FRE52-121R?

A: Yes. Both components share identical electrical specifications (121 Ohms ±1%, 0.6W, ±50ppm/°C, -55°C ~ 155°C), metal film composition, axial package configuration, and regulatory compliance status. The components are mechanically and electrically interchangeable.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components; packaging selection depends on assembly methodology and order quantity requirements.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. MF0207FRE52-121R has a diameter of 0.094" (2.40mm) and length of 0.248" (6.30mm). MRS25000C1210FRP00 has a diameter of 0.098" (2.50mm) and length of 0.256" (6.50mm). These variations are within standard axial resistor tolerances and do not affect electrical performance or mechanical fit in standard through-hole applications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both MF0207FRE52-121R and MRS25000C1210FRP00 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the temperature coefficient specification and why is it important?

A: Both components have a temperature coefficient of ±50ppm/°C, meaning the resistance value changes by a maximum of 50 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision applications requiring stable resistance values across the operating temperature range of -55°C to 155°C.
