Substitute Part Grouping Explanation

Substitute parts for the ERO-S2PHF1101 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 1.1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Number of terminations: 2

Both substitute parts meet these core requirements. The RNMF14FTC1K10 and CMF501K1000FHEB maintain identical electrical specifications while offering active product status and enhanced environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both RNMF14FTC1K10 and CMF501K1000FHEB are suitable substitutes for the obsolete ERO-S2PHF1101. Selection between them depends on application-specific requirements:

The RNMF14FTC1K10 from Stackpole Electronics Inc maintains the closest dimensional profile to the original part and carries ROHS3 compliance with REACH unaffected status. This part is actively manufactured with 23,944 units in stock.

The CMF501K1000FHEB from Vishay Dale offers an extended operating temperature range to 175°C and includes moisture-resistant features in addition to flame retardant coating. This part also carries ROHS3 compliance and REACH unaffected status, with 1,496 units in stock.

Both parts are classified as active products with current manufacturing support, addressing the obsolescence of the original ERO-S2PHF1101.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC1K10 and CMF501K1000FHEB be used interchangeably with ERO-S2PHF1101?

A: Yes. Both substitute parts maintain identical electrical specifications: 1.1 kOhms resistance, ±1% tolerance, 0.25W power rating, and ±50ppm/°C temperature coefficient. All three parts use metal film composition in axial through-hole packages with two terminations.

Q: What are the dimensional differences between the substitute parts?

A: The ERO-S2PHF1101 measures 0.067" diameter by 0.126" length. The RNMF14FTC1K10 is 0.070" diameter by 0.130" length, and the CMF501K1000FHEB is 0.065" diameter by 0.150" length. These minor variations are within typical PCB layout tolerances for axial through-hole components.

Q: Which substitute part has the wider operating temperature range?

A: The CMF501K1000FHEB operates from -55°C to 175°C, compared to the RNMF14FTC1K10 range of -55°C to 155°C. The original ERO-S2PHF1101 operates to 150°C. Selection depends on application thermal requirements.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both RNMF14FTC1K10 and CMF501K1000FHEB are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What is the difference in packaging between the parts?

A: All three parts use axial through-hole packaging. The RNMF14FTC1K10 is supplied in cut tape format with 23,944 units in stock. The CMF501K1000FHEB is also supplied in cut tape format with 1,496 units in stock.
