Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF7502 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 75 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 substitute part RNMF14FTC75K0 from Stackpole Electronics Inc meets all these criteria. Physical dimensions show minor variation within acceptable tolerances for through-hole mounting applications. The substitute maintains identical electrical specifications and is compatible with existing PCB layouts designed for axial resistor footprints.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC75K0 serves as a direct functional equivalent to the obsolete ERO-S2PHF7502. Selection of the substitute is supported by the following factors:

• Electrical specifications are identical across all critical parameters: resistance, tolerance, power rating, temperature coefficient, and operating temperature range
• The substitute maintains active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance of the substitute aligns with current regulatory requirements for electronic component procurement
• Physical dimensions show minor variation (0.003" diameter increase, 0.004" length increase) that remains within standard through-hole PCB design tolerances
• Both components feature identical axial package configuration and two-terminal construction, enabling direct mechanical and electrical substitution on existing circuit boards

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC75K0 be used as a direct replacement for ERO-S2PHF7502 in existing designs?

A: Yes. Both components share identical electrical specifications (75 kOhms ±1%, 0.25W, ±50ppm/°C, metal film construction) and axial package configuration. Minor physical dimension differences fall within standard through-hole mounting tolerances and do not affect PCB compatibility.

Q: What is the difference in operating temperature range between these parts?

A: The ERO-S2PHF7502 operates from -55°C to 150°C, while the RNMF14FTC75K0 operates from -55°C to 155°C. The substitute provides a 5°C extended upper temperature limit, making it suitable for applications requiring the original part's temperature range and beyond.

Q: Why is the ERO-S2PHF7502 listed as obsolete?

A: Panasonic has discontinued this component. The RNMF14FTC75K0 from Stackpole Electronics Inc is an active product offering equivalent electrical and mechanical functionality for new designs and legacy system support.

Q: Are there compliance differences between the two parts?

A: The RNMF14FTC75K0 carries ROHS3 compliance certification, while the ERO-S2PHF7502 does not specify RoHS status. Both components are classified under the same HTSUS code (8533.21.0090) and ECCN (EAR99).

Q: Do the physical dimension differences affect PCB layout?

A: No. The dimensional variations (0.003" diameter, 0.004" length) are minor and remain within standard axial resistor footprint tolerances used in PCB design. Both components are compatible with identical through-hole mounting patterns.
