Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF9102 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 91 kOhms (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 configuration: Axial through-hole (exact match required)
• Number of terminations: 2 (exact match required)

The RNMF14FTC91K0 manufactured by Stackpole Electronics Inc meets all substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC91K0 is a direct functional equivalent to the ERO-S2PHF9102 based on matching electrical specifications and axial package configuration. The substitute part offers the following advantages:

• Active product status with ongoing manufacturing availability
• ROHS3 compliance certification
• REACH unaffected status
• Extended upper operating temperature limit of 155°C versus 150°C
• Flame retardant coating and safety features in metal film construction

Physical dimensions show minor variation (0.070" diameter and 0.130" length versus 0.067" diameter and 0.126" length), which remains within typical PCB layout tolerances for axial through-hole components. Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC91K0 be used as a direct replacement for the ERO-S2PHF9102 in existing designs?

A: Yes. Both parts meet identical electrical specifications: 91 kOhms ±1% tolerance, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. The axial package configuration and two-termination design are identical. Minor physical dimension differences do not affect PCB mounting compatibility for standard through-hole layouts.

Q: What is the significance of the flame retardant coating on the RNMF14FTC91K0?

A: The flame retardant coating and safety features are additional material properties of the Stackpole RNMF series. These do not alter the electrical performance or substitution eligibility. They represent enhanced manufacturing specifications that do not conflict with the original design requirements.

Q: Are there compliance differences between the two parts?

A: The RNMF14FTC91K0 carries ROHS3 compliance and REACH unaffected status certifications. The ERO-S2PHF9102 compliance information was not provided in the original specifications. Both parts share identical ECCN and HTSUS classifications for export and tariff purposes.

Q: Does the extended temperature range of the RNMF14FTC91K0 affect substitution suitability?

A: No. The substitute part's upper operating temperature limit of 155°C exceeds the original part's 150°C specification. This represents equal or superior performance and does not compromise compatibility with designs specified for -55°C to 150°C operation.

Q: What packaging format is available for the RNMF14FTC91K0?

A: The substitute part is supplied in Cut Tape (CT) format, which is standard for automated assembly processes. The original part's packaging format was not specified in the available data.
