Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF5603 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 560 kOhms (exact match required)
• Tolerance: ±1% (precision class match)
• Power rating: 0.25W / 1/4W (thermal capability match)
• Composition: Metal Film (performance characteristics match)
• Temperature coefficient: ±50ppm/°C (stability match)
• Package: Axial through-hole (mechanical compatibility)
• Number of terminations: 2 (pin count match)

The RNMF14FTC560K from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute. Physical dimensions show minor variations within acceptable tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC560K is the qualified substitute for the obsolete ERO-S2PHF5603. Selection is based on:

• Electrical equivalence: All critical parameters (resistance, tolerance, power rating, temperature coefficient) are identical
• Active product status: The substitute is currently in active production, ensuring long-term availability
• Compliance certifications: ROHS3 compliance and REACH unaffected status provide regulatory alignment for modern applications
• Extended temperature range: The substitute operates to 155°C versus 150°C for the original, providing additional thermal margin
• Physical compatibility: Axial package dimensions are within acceptable tolerances for standard through-hole PCB layouts

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC560K be used as a direct replacement for ERO-S2PHF5603 in existing designs?

A: Yes. Both components share identical electrical specifications (560 kOhms, ±1%, 0.25W, ±50ppm/°C) and axial through-hole packaging. Physical dimensions differ by approximately 0.003" in diameter and 0.004" in length, which is within standard PCB hole tolerances.

Q: What is the difference between the two resistors?

A: The primary differences are manufacturer (Panasonic vs. Stackpole), product status (obsolete vs. active), and additional features on the substitute. The RNMF14FTC560K includes flame retardant coating and safety features, operates to 155°C (versus 150°C), and carries ROHS3 and REACH certifications.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both components use standard axial through-hole terminations and fit within conventional PCB hole spacing. The minor dimensional variations do not affect assembly or electrical performance.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The RNMF14FTC560K provides functional equivalence and is actively manufactured, making it the appropriate choice for new designs and replacements.

Q: Does the substitute meet modern regulatory requirements?

A: Yes. The RNMF14FTC560K is ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations for electronic components.
