Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF5602 is determined by strict equivalence across the following parameters:

• Resistance value: 56 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Termination count: 2 (exact match required)

The RNMF14FTC56K0 manufactured by Stackpole Electronics Inc satisfies all substitution criteria. This part maintains identical electrical specifications and compatible physical dimensions within acceptable tolerances for direct circuit board replacement.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC56K0 is the qualified substitute for the obsolete ERO-S2PHF5602. Selection is based on the following factors:

• All critical electrical parameters match exactly: resistance, tolerance, power rating, temperature coefficient, and operating temperature range
• Physical dimensions are compatible within standard PCB assembly tolerances
• The substitute part is in active production status, ensuring long-term availability
• ROHS3 compliance and REACH unaffected status provide regulatory alignment for modern manufacturing environments
• The substitute includes flame retardant coating and safety features, offering enhanced material properties compared to the original part

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC56K0 be used as a direct replacement for the ERO-S2PHF5602?

A: Yes. Both parts share identical electrical specifications (56 kOhms ±1%, 0.25W, ±50ppm/°C, metal film composition) and compatible axial package dimensions. Physical size differences (0.003" diameter and 0.004" length) fall within standard PCB assembly tolerances and do not affect circuit functionality.

Q: What is the primary reason for substitution?

A: The ERO-S2PHF5602 is classified as obsolete. The RNMF14FTC56K0 provides equivalent electrical performance with active production status and improved regulatory compliance.

Q: Are there any operational differences between these parts?

A: The operating temperature range of the substitute extends to 155°C compared to 150°C for the original part. This represents an improvement. Both parts maintain the same temperature coefficient and tolerance specifications across their respective operating ranges.

Q: Does the flame retardant coating on the substitute affect circuit performance?

A: No. The flame retardant coating is a material enhancement that does not alter electrical characteristics, resistance value, tolerance, or temperature coefficient. It provides additional safety properties without affecting circuit operation.

Q: Are there packaging or lead compatibility concerns?

A: Both parts use standard axial through-hole configuration with two terminations. Lead spacing and diameter differences are minimal and compatible with standard PCB hole patterns designed for 1/4W axial resistors.
