Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTD75R0 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 75 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C minimum to 155°C minimum

Mechanical Compatibility Criteria:

• Package type: Axial through-hole
• Number of terminations: 2
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts may differ in physical dimensions (diameter and length) and packaging format (Tape & Reel vs. Cut Tape), provided all electrical specifications and compliance requirements are maintained.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RNF12FTD75R0, RNMF12FTD75R0, and CMF5575R000FKEB—meet the core electrical specifications for 75 Ohm ±1% metal film resistors at 0.5W power rating. All are Active status products and maintain ROHS3 compliance and REACH unaffected status.

RNF12FTD75R0 is the primary specification. It is available in Tape & Reel packaging with standard axial dimensions.

RNMF12FTD75R0 is a Stackpole Electronics Inc alternative from the RNMF (Mini) series, also in Tape & Reel format. This part features reduced physical dimensions (0.093" Dia x 0.250" L) compared to the RNF12FTD75R0, making it suitable for space-constrained PCB layouts while maintaining identical electrical performance.

CMF5575R000FKEB is a Vishay Dale alternative from the CMF series, supplied in Cut Tape format. This part offers the smallest physical footprint (0.090" Dia x 0.240" L) and an extended operating temperature range to -55°C ~ 175°C, with additional moisture-resistant features. The CMF series is appropriate for applications requiring enhanced environmental protection or higher temperature operation within the specified range.

Selection between these parts depends on PCB space availability, packaging logistics requirements, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can RNMF12FTD75R0 be used as a direct replacement for RNF12FTD75R0?

A: Yes. Both parts share identical electrical specifications: 75 Ohms ±1%, 0.5W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The primary difference is physical size; RNMF12FTD75R0 is a miniature variant with reduced diameter and length. Verify PCB footprint compatibility before substitution.

Q: What are the dimensional differences between these parts?

A: RNF12FTD75R0 measures 0.108" Dia x 0.344" L (2.75mm x 8.75mm). RNMF12FTD75R0 measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CMF5575R000FKEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). All are axial through-hole components with identical lead spacing relative to their body lengths.

Q: Does CMF5575R000FKEB offer any performance advantages?

A: CMF5575R000FKEB maintains all core electrical specifications and adds moisture-resistant features. Its operating temperature range extends to 175°C (versus 155°C for RNF and RNMF series), providing additional thermal margin in high-temperature applications. Physical dimensions are the smallest of the three options.

Q: Are there packaging format differences?

A: RNF12FTD75R0 and RNMF12FTD75R0 are supplied in Tape & Reel (TR) format. CMF5575R000FKEB is supplied in Cut Tape (CT) format. Select based on assembly equipment compatibility and procurement volume requirements.

Q: Do all parts meet compliance requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.
