Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERO-S2PHF11R0 is determined by strict equivalence across the following parameters:

• Resistance value: 11 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)

Two substitute parts meet these criteria and are classified as follows:

Direct Manufacturer Substitute: RNMF14FTC11R0 (Stackpole Electronics Inc) — Active product status with identical electrical specifications and axial packaging.

Similar Manufacturer Substitute: CMF5011R000FHEB (Vishay Dale) — Active product status with identical electrical specifications and axial packaging, featuring extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the ERO-S2PHF11R0. Selection between them is based on product availability, compliance status, and operational environment:

RNMF14FTC11R0 (Stackpole Electronics Inc): This part is the primary direct substitute, offering active product status with ROHS3 compliance. The operating temperature range extends to 155°C, providing a 5°C margin above the original specification. Physical dimensions are within acceptable tolerance for standard through-hole PCB layouts. Packaging is available in Cut Tape format.

CMF5011R000FHEB (Vishay Dale): This part provides the widest operating temperature range (-55°C ~ 175°C), offering a 25°C margin above the original specification. ROHS3 compliance is confirmed. Physical dimensions are slightly different, with reduced diameter (0.065" vs. 0.067") and increased length (0.150" vs. 0.126"). Packaging is available in Tape & Reel format. REACH status is listed as affected, requiring verification for applications subject to REACH regulations.

Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC11R0 and CMF5011R000FHEB be used interchangeably with ERO-S2PHF11R0?

A: Both parts meet the electrical specifications (11 Ohms, ±1%, 0.25W, metal film, ±50ppm/°C). Physical dimensions differ slightly; verify PCB layout clearances before substitution, particularly for the CMF5011R000FHEB due to its increased axial length.

Q: What is the significance of the different operating temperature ranges?

A: The ERO-S2PHF11R0 operates to 150°C. RNMF14FTC11R0 extends to 155°C and CMF5011R000FHEB to 175°C. Both substitutes maintain the specified tolerance and temperature coefficient within their respective ranges. Selection depends on the application's maximum operating temperature requirement.

Q: Are there packaging format differences I should consider?

A: RNMF14FTC11R0 is supplied in Cut Tape (CT) format. CMF5011R000FHEB is supplied in Tape & Reel (TR) format. Both are standard through-hole axial packages suitable for manual or automated assembly. Verify your procurement and assembly processes support the selected packaging format.

Q: What compliance certifications apply to these substitutes?

A: Both RNMF14FTC11R0 and CMF5011R000FHEB are ROHS3 compliant. CMF5011R000FHEB carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications with the original part.

Q: How do physical dimensions affect PCB design?

A: The ERO-S2PHF11R0 measures 0.067" diameter × 0.126" length. RNMF14FTC11R0 is 0.070" diameter × 0.130" length (minimal difference). CMF5011R000FHEB is 0.065" diameter × 0.150" length (shorter diameter, longer axial length). Verify hole spacing and component clearances on your PCB layout before final substitution.

Q: What is the difference between "Direct Manufacturer" and "Similar Manufacturer" classifications?

A: Direct Manufacturer substitutes (RNMF14FTC11R0) are from the same product family lineage with minimal dimensional variation. Similar Manufacturer substitutes (CMF5011R000FHEB) meet all electrical and functional requirements but may have different dimensional characteristics or feature sets. Both are valid engineering substitutes based on the specified parameters.
