ERJ-S14J274U Equivalent & Substitute Parts

Part Overview

The ERJ-S14J274U is a 270 kOhms ±5% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part is rated for automotive applications under AEC-Q200 and features anti-sulfur protection. The product is currently active and available in high volume inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative manufacturers, or when supply chain optimization requires component standardization across production batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14J274U is determined by strict equivalence across the following parameters:

• Resistance value: 270 kOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3

All identified substitute parts meet these electrical and mechanical requirements. Differences in product status, manufacturer, and physical dimensions (height) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S14J274U (Primary Selection): Active product status with anti-sulfur protection. Recommended for new designs and ongoing production requiring Panasonic sourcing.

CRCW1210270KJNEA (Preferred Alternative): Active product status from Vishay Dale with higher inventory availability (16,446 pcs). Functionally equivalent with 0.004" lower seated height. Suitable for designs requiring multi-source qualification or Vishay component standardization.

ERJ-14YJ274U (Legacy Alternative): Marked as "Not For New Designs" by manufacturer. Functionally equivalent but should be used only for legacy product support or when primary alternatives are unavailable. Higher inventory (9,103 pcs) may support obsolescence mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14YJ274U be used in new designs? A: No. This part is designated "Not For New Designs" by Panasonic. Use ERJ-S14J274U or CRCW1210270KJNEA for new product development.

Q: Are all three parts mechanically interchangeable on the PCB? A: Yes. All parts use the 1210 (3225 Metric) package with identical footprints. The height difference between ERJ-S14J274U/ERJ-14YJ274U (0.70mm) and CRCW1210270KJNEA (0.60mm) does not affect PCB assembly compatibility.

Q: Do all substitute parts meet automotive AEC-Q200 requirements? A: Yes. All three parts carry AEC-Q200 certification and are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: What is the difference between ERJ-S14J274U and ERJ-14YJ274U? A: Both are Panasonic 270 kOhms ±5% 1210 resistors with identical electrical specifications. The primary difference is product status: ERJ-S14J274U is active for new designs, while ERJ-14YJ274U is obsolete for new designs. ERJ-S14J274U includes anti-sulfur protection.

Q: Are all parts RoHS3 compliant? A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which part should be selected for supply chain redundancy? A: CRCW1210270KJNEA from Vishay Dale provides cross-manufacturer qualification. Combined with ERJ-S14J274U from Panasonic, this dual-source strategy ensures supply continuity while maintaining full electrical and mechanical equivalence.
