Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERO-S2PHF1501 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 1.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W, 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)

The identified substitute parts meet all critical electrical specifications and maintain mechanical compatibility with the original design. Physical dimensions may vary within acceptable tolerances for axial through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are actively manufactured and available in production quantities, addressing the obsolescence status of the ERO-S2PHF1501. The RNMF14FTC1K50 from Stackpole Electronics Inc and CMF501K5000FHEB from Vishay Dale meet all specified electrical and mechanical requirements.

The RNMF14FTC1K50 provides ROHS3 compliance and flame retardant coating with an extended operating temperature range to 155°C. The CMF501K5000FHEB offers ROHS3 compliance, flame retardant coating, moisture resistant construction, and the highest operating temperature range at 175°C. Both parts carry REACH Unaffected status.

Selection between these substitutes depends on application-specific requirements regarding temperature extremes and environmental exposure. For applications operating within the original -55°C to 150°C range, either substitute is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC1K50 or CMF501K5000FHEB be used as direct replacements for ERO-S2PHF1501?

A: Yes. Both parts match the critical electrical specifications (1.5 kOhms, ±1% tolerance, 0.25W power rating, metal film composition, ±50ppm/°C temperature coefficient) and mechanical package type (axial, 2 terminations). Physical dimensions vary slightly but remain compatible with standard axial through-hole mounting.

Q: What is the difference between the two substitute parts?

A: Both meet core electrical requirements. The CMF501K5000FHEB extends the operating temperature range to 175°C and includes moisture resistant construction, compared to the RNMF14FTC1K50 which operates to 155°C. Both include flame retardant coating and ROHS3 compliance.

Q: Are there packaging differences between the main part and substitutes?

A: The main part is specified as standard axial packaging. Substitutes are supplied in Cut Tape (CT) packaging format. Both formats are compatible with standard axial through-hole assembly processes.

Q: Do the substitute parts meet regulatory compliance requirements?

A: Both RNMF14FTC1K50 and CMF501K5000FHEB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Which substitute should be selected for high-temperature applications?

A: The CMF501K5000FHEB supports operation to 175°C, providing the widest temperature margin above the original specification of 150°C.
