ERJ-S14F2741U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2741U is a 2.74 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 665 units available in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative sourcing, or when supply chain optimization requires qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2741U is determined by strict equivalence across the following parameters:

• Resistance value: 2.74 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All qualified substitutes must match these parameters without deviation. Substitute parts are grouped by manufacturer and product status to facilitate sourcing decisions.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ERJ-S14F2741U

The ERJ-S14F2741U maintains active product status and is the specified component for new designs. This part includes anti-sulfur protection and is recommended for applications requiring the latest manufacturing process and long-term availability assurance.

Secondary Selection: CRCW12102K74FKEA

The CRCW12102K74FKEA from Vishay Dale is an active product that meets all electrical and mechanical specifications. This part is suitable as a direct substitute when Panasonic supply is constrained. The seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the primary part; this difference is within standard PCB assembly tolerances and does not affect functional performance.

Tertiary Selection: ERJ-14NF2741U

The ERJ-14NF2741U is designated "Not For New Designs" and should be used only for legacy system maintenance or repair applications where design continuity is required. This part carries the same electrical specifications but is subject to discontinuation planning.

Frequently Asked Questions (FAQ)

Q: Can CRCW12102K74FKEA be used as a direct replacement for ERJ-S14F2741U?

A: Yes. Both parts meet identical electrical specifications (2.74 kOhms ±1%, 0.5W, ±100ppm/°C, -55°C ~ 155°C) and package requirements (1210 / 3225 Metric). Both are AEC-Q200 qualified and ROHS3 compliant. The 0.004" (0.10mm) difference in seated height is within standard PCB assembly tolerances.

Q: Why is ERJ-14NF2741U marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent, it should not be selected for new product designs due to potential future discontinuation. It remains suitable for maintenance and repair of existing systems.

Q: Are all three parts interchangeable in automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. They are electrically and mechanically interchangeable for automotive circuit applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What is the significance of the anti-sulfur feature on ERJ-S14F2741U?

A: The anti-sulfur protection on the ERJ-S14F2741U provides enhanced reliability in environments with sulfur-containing contaminants. This feature is specific to the Panasonic ERJ-S14 series and is not present on the ERJ-14NF or CRCW alternatives. For applications in high-sulfur environments, the ERJ-S14F2741U is the preferred choice.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All three parts meet AEC-Q200 qualification and carry identical electrical specifications. Selection should be based on supply availability, product status (active vs. not for new designs), and specific environmental requirements such as sulfur exposure.
