Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF2703 is determined by strict equivalence across the following critical parameters:

• Resistance value: 270 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Package configuration: Axial through-hole
• Operating temperature range: Minimum -55°C to 150°C or higher

The RNMF14FTC270K from Stackpole Electronics Inc meets all substitution criteria. This part maintains identical electrical specifications and package form factor, with an extended upper operating temperature limit of 155°C, providing additional thermal margin. The substitute is currently in active production status with high inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC270K is the direct substitute for the obsolete ERO-S2PHF2703. Selection is based on the following factors:

• Electrical equivalence across all critical parameters (resistance, tolerance, power rating, temperature coefficient)
• Active production status ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Extended operating temperature range providing additional design margin
• Flame retardant coating and safety features in the substitute part offer enhanced reliability characteristics
• Identical axial package configuration enabling direct mechanical and electrical substitution without circuit board redesign

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC270K be used as a direct replacement for the ERO-S2PHF2703?

A: Yes. Both parts share identical resistance value, tolerance, power rating, temperature coefficient, and axial package configuration. The substitute meets or exceeds all electrical and mechanical requirements of the original part.

Q: What is the difference in physical dimensions between these parts?

A: The ERO-S2PHF2703 measures 0.067" diameter × 0.126" length (1.70mm × 3.20mm). The RNMF14FTC270K measures 0.070" diameter × 0.130" length (1.78mm × 3.30mm). These dimensional differences are within typical axial resistor tolerances and do not affect circuit board layout compatibility for standard through-hole applications.

Q: Why is the original part listed as obsolete?

A: The ERO-S2PHF2703 has been discontinued by Panasonic Electronic Components. The RNMF14FTC270K from Stackpole Electronics Inc is an active production equivalent that provides continued availability for this resistance value and specification class.

Q: Are there compliance differences between the two parts?

A: The substitute part carries ROHS3 compliance and REACH unaffected status certifications. The original part specifications do not document these compliance statuses. Both parts carry the same ECCN and HTSUS classifications.

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

A: The RNMF14FTC270K includes flame retardant coating and safety features as standard characteristics. These features enhance reliability in applications subject to thermal stress or safety-critical requirements, while maintaining full electrical equivalence to the original part.
