ERO-S2PHF6203 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF6203 is a 620 kOhms ±1% 0.25W axial metal film through-hole resistor manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production, maintenance, and repair applications. Substitute parts must maintain identical electrical specifications and compatible physical dimensions to ensure direct board-level replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF6203 is determined by strict equivalence across the following parameters:

• Resistance value: 620 kOhms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (required for performance equivalence)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Package: Axial through-hole configuration
• Number of terminations: 2

The RNMF14FTC620K from Stackpole Electronics Inc meets all mandatory electrical parameters and maintains compatible physical dimensions within acceptable manufacturing tolerances for axial resistor packages.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC620K is a direct functional equivalent for the obsolete ERO-S2PHF6203. Both components share identical electrical specifications: 620 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Physical dimensions are within acceptable tolerances for axial through-hole resistor packages, permitting direct board-level substitution without layout modification.

The RNMF14FTC620K offers additional advantages: active product status ensures ongoing availability, ROHS3 compliance supports modern manufacturing standards, and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 150°C) provides broader environmental compatibility. The flame retardant coating and safety features of the RNMF series do not compromise electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC620K be used as a direct replacement for the ERO-S2PHF6203?

A: Yes. Both components meet identical electrical specifications: 620 kOhms ±1%, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Physical dimensions are compatible for axial through-hole mounting.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. The ERO-S2PHF6203 measures 0.067" diameter × 0.126" length; the RNMF14FTC620K measures 0.070" diameter × 0.130" length. These differences do not affect board-level compatibility for standard PCB layouts.

Q: Does the flame retardant coating on the RNMF14FTC620K affect electrical performance?

A: No. The flame retardant coating is a physical feature that does not alter the electrical characteristics of the metal film resistor. Resistance value, tolerance, temperature coefficient, and power rating remain unchanged.

Q: What is the significance of the ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the RNMF14FTC620K meets current environmental and hazardous substance restrictions, supporting compliance with modern manufacturing and regulatory standards. The original ERO-S2PHF6203 does not specify RoHS status.

Q: Is the extended operating temperature range of the RNMF14FTC620K (-55°C ~ 155°C) a concern?

A: No. The extended upper temperature limit of 155°C versus 150°C represents an advantage, providing broader environmental compatibility without compromising performance within the original specification range.

Q: Can these parts be used interchangeably in all applications?

A: Yes, provided the application operates within the overlapping temperature range (-55°C ~ 150°C). Both components are functionally equivalent for all standard resistive applications requiring 620 kOhms ±1% at 0.25W.
