ERO-S2PHF9103 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF9103 is a 910 kOhms ±1% 0.25W through-hole resistor with axial metal film construction manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The metal film composition provides stable performance across the operating temperature range of -55°C to 150°C with a temperature coefficient of ±50ppm/°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF9103 is determined by the following critical parameters:

• Resistance Value: 910 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: Minimum -55°C to 150°C (substitute must meet or exceed this range)

The RNMF14FTC910K from Stackpole Electronics Inc meets all substitution criteria. This part maintains identical electrical specifications and package configuration while offering enhanced features including flame retardant coating and an extended upper operating temperature limit of 155°C.

Engineering Selection Recommendations

The RNMF14FTC910K is the qualified substitute for the obsolete ERO-S2PHF9103. Selection is based on:

• Electrical Equivalence: Identical resistance, tolerance, power rating, temperature coefficient, and composition specifications ensure direct functional replacement.
• Product Status: The substitute is an active product with established supply chain availability, addressing the obsolescence of the original part.
• Compliance: The RNMF14FTC910K carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.
• Thermal Performance: The extended upper operating temperature of 155°C provides additional thermal margin compared to the original 150°C specification.
• Physical Compatibility: Dimensional differences (0.070" Dia x 0.130" L versus 0.067" Dia x 0.126" L) are within typical PCB layout tolerances for axial through-hole components.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC910K be used as a direct replacement for the ERO-S2PHF9103?

A: Yes. Both parts share identical electrical specifications: 910 kOhms ±1% at 0.25W with ±50ppm/°C temperature coefficient and metal film construction. The axial package configuration is compatible with existing PCB designs.

Q: What are the physical dimension differences between these parts?

A: The ERO-S2PHF9103 measures 0.067" Dia x 0.126" L (1.70mm x 3.20mm), while the RNMF14FTC910K measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm). These differences are minimal and do not affect standard through-hole PCB layouts.

Q: Does the RNMF14FTC910K offer any performance advantages?

A: The substitute provides an extended upper operating temperature limit of 155°C compared to 150°C for the original part, and includes flame retardant coating with safety features. Both parts maintain the same temperature coefficient and tolerance specifications.

Q: What is the compliance status of the substitute part?

A: The RNMF14FTC910K is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Is the RNMF14FTC910K currently available?

A: Yes. The substitute is an active product with established supply chain availability, unlike the obsolete ERO-S2PHF9103.
