Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF2202 is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 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)
• Number of terminations: 2 (exact match required)

The RNMF14FTC22K0 manufactured by Stackpole Electronics Inc meets all critical electrical and mechanical parameters required for direct substitution. This part maintains identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. Physical dimensions are within acceptable tolerance for axial package types. The substitute part carries active product status and includes additional features such as flame retardant coating and safety certification.

Engineering Selection Recommendations

The RNMF14FTC22K0 is the direct substitute for the ERO-S2PHF2202. Selection is based on the following factors:

• All critical electrical parameters match exactly: resistance, tolerance, power rating, temperature coefficient, and composition
• Operating temperature range of the substitute (-55°C ~ 155°C) exceeds the original part specification (-55°C ~ 150°C), providing extended thermal capability
• The substitute part maintains active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status of the substitute part satisfy modern regulatory requirements
• Physical dimensions of the axial package are compatible with existing PCB layouts designed for the original component
• Flame retardant coating and safety features of the substitute part provide additional performance characteristics

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC22K0 be used as a direct replacement for the ERO-S2PHF2202?

A: Yes. The RNMF14FTC22K0 meets all critical electrical and mechanical specifications required for direct substitution. Resistance, tolerance, power rating, temperature coefficient, and axial package configuration are identical. Physical dimensions are within acceptable tolerance for axial through-hole components.

Q: What is the difference in operating temperature range between these parts?

A: The ERO-S2PHF2202 operates from -55°C to 150°C. The RNMF14FTC22K0 operates from -55°C to 155°C. The substitute part provides 5°C additional upper temperature capability, which is beneficial for applications requiring extended thermal performance.

Q: Are there compliance differences between the original and substitute part?

A: The RNMF14FTC22K0 is ROHS3 compliant and REACH unaffected. Compliance status for the original ERO-S2PHF2202 is not specified in available documentation. The substitute part satisfies current regulatory requirements for electronic components.

Q: Does the flame retardant coating on the RNMF14FTC22K0 affect electrical performance?

A: No. The flame retardant coating is a safety feature that does not alter the electrical characteristics specified in the parameter comparison table. All electrical parameters remain identical to the original part.

Q: Are the physical dimensions compatible with existing PCB designs?

A: Yes. Both parts use axial package configuration with two terminations. The ERO-S2PHF2202 measures 0.067" Dia x 0.126" L (1.70mm x 3.20mm). The RNMF14FTC22K0 measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm). These dimensional variations are within acceptable tolerance for axial through-hole component placement and do not require PCB redesign.
