Substitute Part Grouping Explanation

Substitution for the ERO-S2PHF1603 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 160 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Package configuration: Axial through-hole
• Number of terminations: 2

The RNMF14FTC160K from Stackpole Electronics Inc meets all these criteria. Both parts are metal film axial resistors with identical electrical specifications and compatible physical dimensions within standard PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC160K is the direct substitute for the ERO-S2PHF1603 based on electrical equivalence and active product status. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status support modern regulatory requirements
• Flame retardant coating and safety features provide enhanced reliability
• Operating temperature range extends to 155°C, exceeding the original specification of 150°C
• Physical dimensions (0.070" Dia x 0.130" L) are within standard PCB assembly tolerances relative to the original (0.067" Dia x 0.126" L)

Selection of the RNMF14FTC160K eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with applications designed for the ERO-S2PHF1603.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC160K be used as a direct replacement for the ERO-S2PHF1603?

A: Yes. Both parts are 160 kOhms ±1% metal film axial resistors with 0.25W power rating and ±50ppm/°C temperature coefficient. Electrical specifications are identical. Physical dimensions are within standard PCB assembly tolerances.

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

A: The ERO-S2PHF1603 measures 0.067" Dia x 0.126" L (1.70mm x 3.20mm). The RNMF14FTC160K measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm). The difference is approximately 0.003" in diameter and 0.004" in length, which does not affect standard PCB footprint compatibility.

Q: Why is the ERO-S2PHF1603 listed as obsolete?

A: The ERO series represents a legacy product line from Panasonic Electronic Components. The RNMF14FTC160K from Stackpole Electronics Inc is an active product that provides equivalent functionality with modern compliance certifications.

Q: Does the RNMF14FTC160K meet current regulatory requirements?

A: Yes. The RNMF14FTC160K is ROHS3 compliant and REACH unaffected, supporting current regulatory standards for electronic components.

Q: Are there any temperature range differences?

A: The ERO-S2PHF1603 operates from -55°C to 150°C. The RNMF14FTC160K operates from -55°C to 155°C. The substitute part extends the upper operating temperature by 5°C, providing additional thermal margin.
