Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF82R0 is determined by strict equivalence across the following parameters:

• Resistance Value: 82 Ohms (exact match required)
• Tolerance: ±1% (maintains precision specifications)
• Power Rating: 0.25W / 1/4W (electrical stress rating)
• Composition: Metal Film (electrical performance characteristics)
• Temperature Coefficient: ±50ppm/°C (thermal stability)
• Package Configuration: Axial Through Hole (mechanical and PCB compatibility)
• Termination Count: 2 (circuit interface requirement)

The RNMF14FTC82R0 from Stackpole Electronics Inc satisfies all substitution criteria. Physical dimensions show minor variation (0.070" Dia x 0.130" L versus 0.067" Dia x 0.126" L), which remains within acceptable tolerances for axial component placement in standard through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC82R0 qualifies as a direct functional substitute for the ERO-S2PHF82R0 based on electrical parameter equivalence. The substitute component is currently in active production status, ensuring supply chain continuity and availability. The RNMF14FTC82R0 carries ROHS3 compliance certification, meeting modern regulatory requirements for electronic component manufacturing.

Physical dimensions of the substitute show minor increases (0.003" in diameter, 0.004" in length), which do not impact standard through-hole PCB layouts. The operating temperature range of the substitute (-55°C to 155°C) exceeds the original specification (-55°C to 150°C), providing additional thermal margin.

Selection of the RNMF14FTC82R0 is supported by product availability (18,630 units in stock versus 1,023 for the original) and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC82R0 be used as a direct replacement for the ERO-S2PHF82R0?

A: Yes. Both components share identical electrical specifications: 82 Ohms, ±1% tolerance, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Both are configured as 2-termination axial through-hole components suitable for standard PCB applications.

Q: What are the physical differences between these components?

A: The RNMF14FTC82R0 has slightly larger dimensions: 0.070" diameter (versus 0.067") and 0.130" length (versus 0.126"). These differences are within acceptable tolerances for axial component placement and do not affect circuit performance or PCB compatibility.

Q: Does the substitute component meet current compliance standards?

A: The RNMF14FTC82R0 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. The original ERO-S2PHF82R0 compliance status is not specified in available documentation.

Q: What is the temperature operating range difference?

A: The ERO-S2PHF82R0 operates from -55°C to 150°C. The RNMF14FTC82R0 operates from -55°C to 155°C, providing an additional 5°C of upper temperature margin.

Q: Are there any packaging differences?

A: The ERO-S2PHF82R0 is supplied in standard packaging. The RNMF14FTC82R0 is available in Cut Tape (CT) packaging, which is standard for active production components and facilitates automated assembly processes.

Q: Why is the original component listed as obsolete?

A: The ERO-S2PHF82R0 is classified as obsolete by Panasonic Electronic Components, indicating discontinued production. The RNMF14FTC82R0 remains in active production, ensuring long-term availability and supply chain stability.
