Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF3001 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 3 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: minimum -55°C, maximum ≥150°C
• Package: Axial through-hole
• Number of terminations: 2

The RNMF14FTC3K00 from Stackpole Electronics Inc meets all substitution criteria. This part maintains identical electrical specifications while offering enhanced features including flame retardant coating and safety-rated construction. The operating temperature range extends to 155°C, exceeding the original specification. Physical dimensions show minor variation (0.070" Dia x 0.130" L versus 0.067" Dia x 0.126" L), which remains within acceptable tolerance for axial through-hole component placement in standard PCB designs.

Engineering Selection Recommendations

The RNMF14FTC3K00 is the direct substitute for the ERO-S2PHF3001. Selection is based on the following factors:

• Electrical equivalence across all critical parameters (resistance, tolerance, power rating, temperature coefficient)
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components
• Extended operating temperature range (155°C maximum) providing additional thermal margin
• Flame retardant coating and safety-rated construction offering enhanced reliability characteristics
• Axial package compatibility with existing PCB designs and assembly processes

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC3K00 be used as a direct replacement for the ERO-S2PHF3001 in existing designs?

A: Yes. Both components share identical electrical specifications (3 kOhms, ±1%, 0.25W, ±50ppm/°C) and axial through-hole packaging. The substitute part meets or exceeds all performance requirements of the original component.

Q: What is the significance of the flame retardant coating on the RNMF14FTC3K00?

A: The flame retardant coating and safety-rated construction are additional features of the substitute part. These do not affect electrical performance but provide enhanced safety characteristics suitable for applications requiring higher reliability standards.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variation exists. The ERO-S2PHF3001 measures 0.067" Dia x 0.126" L, while the RNMF14FTC3K00 measures 0.070" Dia x 0.130" L. These differences are within acceptable tolerance for standard axial through-hole component placement and do not require PCB redesign.

Q: What compliance certifications apply to the substitute part?

A: The RNMF14FTC3K00 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution and use in regulated markets.

Q: Why is the original ERO-S2PHF3001 classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The RNMF14FTC3K00 remains in active production, ensuring availability for new designs and ongoing support of legacy applications.
