ERJ-S14F2263U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2263U is a 226 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, designed for automotive and industrial applications requiring high reliability in harsh environments. The part is currently in active production status with 1124 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward alternative feature sets such as pulse withstanding capability, or when legacy series parts require transition to current production lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2263U is determined by strict equivalence across the following parameters:

• Resistance value: 226 kOhms (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 qualified substitutes maintain identical electrical and mechanical specifications. Differences in product status, series designation, and specific feature enhancements (such as anti-sulfur or pulse withstanding capability) do not affect functional interchangeability in applications where the core parameters are met.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S14F2263U (Primary Part): Active production status with anti-sulfur feature. Recommended for new designs requiring enhanced corrosion resistance in automotive environments.

ERJ-P14F2263U (Preferred Substitute): Active production status with pulse withstanding capability. Suitable for applications requiring transient overvoltage protection. Highest inventory availability (15498 units). Recommended as primary substitute for new designs.

ERJ-14NF2263U (Legacy Substitute): Marked as "Not For New Designs." Acceptable only for legacy system maintenance or replacement in existing production lines where design freeze conditions apply. Highest inventory level (12305 units) may support high-volume legacy applications.

All three parts maintain identical core electrical and mechanical specifications, ensuring direct functional interchangeability. Selection between active parts (ERJ-S14F2263U and ERJ-P14F2263U) should be based on application-specific requirements for anti-sulfur or pulse withstanding features.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F2263U replace ERJ-S14F2263U in automotive applications?

A: Yes. Both parts meet identical electrical specifications (226 kOhms ±1%, 0.5W, 1210 package) and carry AEC-Q200 automotive qualification. The ERJ-P14F2263U adds pulse withstanding capability, which does not conflict with applications designed for the ERJ-S14F2263U. The primary difference is the anti-sulfur feature in ERJ-S14F2263U versus pulse withstanding in ERJ-P14F2263U.

Q: Is ERJ-14NF2263U suitable for new product designs?

A: No. ERJ-14NF2263U carries "Not For New Designs" status. This part is reserved for legacy system support and replacement applications only. For new designs, use ERJ-S14F2263U or ERJ-P14F2263U.

Q: Do all three parts use the same 1210 package footprint?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and maximum seated height (0.028" / 0.70mm). PCB footprints are interchangeable.

Q: What is the difference between anti-sulfur and pulse withstanding features?

A: Anti-sulfur coating (ERJ-S14F2263U) protects against sulfur-induced corrosion in harsh automotive environments. Pulse withstanding (ERJ-P14F2263U) provides transient overvoltage protection. These are distinct features addressing different environmental or electrical stress conditions. Application requirements determine which feature is necessary.

Q: Are all three parts RoHS3 compliant?

A: Yes. ERJ-S14F2263U, ERJ-14NF2263U, and ERJ-P14F2263U are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.
