Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F23R2U are qualified based on the following electrical and mechanical parameters:

• Resistance value: 23.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All substitute parts listed maintain identical electrical performance and mechanical compatibility with the main part number across these critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F23R2U (Panasonic ERJ-S14 series) is the primary specification for new designs. This part maintains active production status and includes anti-sulfur protection, making it suitable for long-term supply chain planning.

The ERJ-14NF23R2U (Panasonic ERJ-14N series) is electrically and mechanically identical but carries a "Not For New Designs" status. This part may be used for legacy system support or design revisions where existing inventory must be maintained, but should not be selected for new product development.

The RMCF1210FT23R2 (Stackpole Electronics) is an active production alternative from a different manufacturer. This part provides equivalent electrical performance and automotive qualification. Selection of this substitute is appropriate when primary source availability is constrained or when multi-source qualification is required for supply chain resilience.

All three parts satisfy identical compliance requirements including ROHS3 and AEC-Q200 automotive standards.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF23R2U be used as a direct replacement for ERJ-S14F23R2U?

A: Yes, from an electrical and mechanical standpoint. However, ERJ-14NF23R2U carries "Not For New Designs" status. Use this part only for legacy system maintenance or existing inventory management. For new product development, specify ERJ-S14F23R2U or RMCF1210FT23R2.

Q: What is the difference between ERJ-S14 and ERJ-14N series?

A: Both series are manufactured by Panasonic and share identical electrical specifications for this 23.2 Ohm value. The primary difference is product lifecycle status: ERJ-S14 is active production, while ERJ-14N is not recommended for new designs.

Q: Is RMCF1210FT23R2 from Stackpole Electronics fully compatible?

A: Yes. The RMCF1210FT23R2 matches all critical parameters: 23.2 Ohm resistance, ±1% tolerance, 0.5W power rating, 1210 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. It is suitable for direct substitution.

Q: Are there any anti-sulfur differences between these parts?

A: The ERJ-S14F23R2U explicitly includes anti-sulfur protection. The ERJ-14NF23R2U and RMCF1210FT23R2 specifications provided do not list anti-sulfur as a feature. If anti-sulfur protection is a design requirement, confirm this specification with the manufacturer before substitution.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm) and height (0.028" / 0.70mm maximum). No PCB layout modifications are required for substitution.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.
