Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF3603 is determined by strict equivalence across the following critical parameters:

• Resistance value: 360 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 RNMF14FTC360K from Stackpole Electronics Inc meets all these requirements and qualifies as a direct substitute. Both parts maintain identical electrical specifications and package footprints suitable for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC360K is the qualified substitute for the obsolete ERO-S2PHF3603. Selection is based on the following factors:

• All critical electrical parameters match exactly: resistance, tolerance, power rating, temperature coefficient, and operating temperature range
• Both components use identical metal film construction and axial package configuration
• The RNMF14FTC360K maintains active product status, ensuring long-term availability and supply chain continuity
• The substitute offers ROHS3 compliance and flame retardant coating with safety features, providing enhanced environmental and safety compliance
• Physical dimensions are within acceptable tolerance for standard PCB through-hole mounting applications
• The operating temperature range of the substitute (-55°C to 155°C) exceeds the original specification, providing additional thermal margin

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC360K be used as a direct replacement for the ERO-S2PHF3603?

A: Yes. Both components share identical electrical specifications (360 kOhms, ±1%, 0.25W, ±50ppm/°C) and axial package configuration. The substitute is suitable for direct PCB substitution in existing designs.

Q: What are the physical dimension differences between these parts?

A: The ERO-S2PHF3603 measures 0.067" diameter by 0.126" length, while the RNMF14FTC360K measures 0.070" diameter by 0.130" length. These minor differences are within standard PCB through-hole tolerances and do not affect mounting compatibility.

Q: Does the RNMF14FTC360K offer any additional benefits?

A: The substitute includes flame retardant coating and safety features. It is ROHS3 compliant and REACH unaffected, providing enhanced environmental compliance compared to the obsolete original part.

Q: Are there any temperature range considerations?

A: The RNMF14FTC360K operates from -55°C to 155°C, compared to the original -55°C to 150°C specification. This provides an additional 5°C of upper temperature margin, suitable for applications requiring extended thermal performance.

Q: What is the availability status of the substitute?

A: The RNMF14FTC360K is classified as active product status with 2826 pieces in stock, ensuring reliable supply chain availability for production and repair applications.
