ERO-S2PHF1000 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF1000 is a 100 Ohm ±1% 1/4W axial metal film through-hole resistor manufactured by Panasonic Electronic Components. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF1000 is determined by strict alignment of the following parameters:

• Resistance value: 100 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 (exact match required)
• Number of terminations: 2 (exact match required)

Both identified substitute parts meet all mandatory electrical and mechanical criteria. Physical dimensions show minor variations within acceptable tolerances for axial through-hole mounting. Operating temperature ranges exceed the original specification, providing enhanced thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Both RNMF14FTC100R and CMF50100R00FHEB are active production components that satisfy all electrical and mechanical substitution criteria for the obsolete ERO-S2PHF1000.

RNMF14FTC100R (Stackpole Electronics Inc) provides direct functional equivalence with flame retardant coating and safety features. This part maintains the closest dimensional profile and extends the operating temperature range to 155°C.

CMF50100R00FHEB (Vishay Dale) offers the widest operating temperature range (-55°C ~ 175°C) and includes moisture-resistant properties in addition to flame retardant coating. Both substitute parts carry ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

Selection between these two substitutes should be based on supply chain availability, packaging format requirements (both available in Cut Tape), and specific application thermal demands.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC100R or CMF50100R00FHEB be used as direct replacements for ERO-S2PHF1000?

A: Yes. Both parts match the mandatory electrical specifications (100 Ohms, ±1%, 0.25W, metal film composition, ±50ppm/°C temperature coefficient) and mechanical package type (axial, 2 terminations). Physical dimensions show minor variations acceptable for through-hole mounting applications.

Q: What is the difference between the two substitute parts?

A: Both meet substitution criteria. RNMF14FTC100R operates to 155°C; CMF50100R00FHEB operates to 175°C and includes moisture-resistant properties. CMF50100R00FHEB has a longer axial length (0.150" vs 0.130").

Q: Are there packaging considerations when switching to substitute parts?

A: Both substitutes are supplied in Cut Tape (CT) packaging. Verify compatibility with your assembly equipment and handling procedures. Physical dimensions show minor variations; confirm PCB layout accommodates the dimensional differences, particularly the axial length of CMF50100R00FHEB.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both RNMF14FTC100R and CMF50100R00FHEB are ROHS3 compliant and REACH unaffected, supporting current regulatory requirements for electronic component procurement.

Q: Why is the ERO-S2PHF1000 listed as obsolete?

A: Panasonic has discontinued this product line. Active production alternatives with equivalent specifications are available from Stackpole Electronics Inc and Vishay Dale to support ongoing design and maintenance requirements.
