Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAC75R0 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Package type: Axial through-hole (exact match required)
• Compliance: ROHS3 Compliant (minimum requirement)

Physical dimensions and packaging format (Tape & Box vs. Cut Tape) do not affect electrical substitutability. Operating temperature range variations within or exceeding the specified -55°C ~ 155°C are acceptable provided the substitute meets or exceeds this range.

Engineering Selection Recommendations

All three parts meet the core electrical requirements for 75 Ohm ±1% 1/4W metal film axial resistor applications. Selection between RNF14FAC75R0, RNMF14FTC75R0, and CMF5075R000FHEB depends on specific application constraints:

RNMF14FTC75R0 is a direct Stackpole Electronics Inc substitute with identical electrical specifications and operating temperature range. The RNMF series represents a miniaturized variant with reduced physical dimensions (0.070" Dia x 0.130" L versus 0.093" Dia x 0.250" L), suitable for space-constrained PCB layouts. Both Stackpole parts maintain ROHS3 compliance and identical temperature coefficient performance.

CMF5075R000FHEB from Vishay Dale provides an extended operating temperature range (-55°C ~ 175°C) and includes moisture-resistant features beyond the base flame retardant coating. This part is suitable for applications requiring enhanced environmental protection. Physical dimensions fall between the standard and miniaturized variants.

All substitute parts are Active status products with established supply availability and ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC75R0 be used as a direct replacement for RNF14FAC75R0?

A: Yes. Both parts share identical electrical specifications: 75 Ohms ±1%, 0.25W power rating, ±50ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The primary difference is physical size; RNMF14FTC75R0 is a miniaturized variant. Substitution is valid provided PCB layout accommodates the smaller dimensions (0.070" Dia x 0.130" L).

Q: What are the dimensional differences between substitute parts?

A: RNF14FAC75R0 measures 0.093" Dia x 0.250" L. RNMF14FTC75R0 measures 0.070" Dia x 0.130" L (miniaturized). CMF5075R000FHEB measures 0.065" Dia x 0.150" L. Smaller dimensions may require PCB footprint verification before substitution.

Q: Does CMF5075R000FHEB offer advantages over Stackpole parts?

A: CMF5075R000FHEB extends the operating temperature range to -55°C ~ 175°C (versus -55°C ~ 155°C) and includes moisture-resistant features. These characteristics are beneficial for high-temperature or humid environments. Electrical performance remains equivalent across all three parts.

Q: Are packaging format differences (Tape & Box vs. Cut Tape) significant?

A: Packaging format affects supply chain logistics and handling but does not impact electrical or mechanical substitutability. Tape & Box (TB) and Cut Tape (CT) formats contain identical components; selection depends on assembly process requirements and inventory management practices.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. RNF14FAC75R0, RNMF14FTC75R0, and CMF5075R000FHEB are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
