ERJ-S14F2702U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2702U is a 27 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2702U is determined by strict equivalence across the following critical parameters:

• Resistance value: 27 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 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

The ERJ-14NF2702U meets all substitution criteria. While the ERJ-14N series is designated "Not For New Designs," it maintains complete electrical and mechanical compatibility with the ERJ-S14F2702U. The primary distinction is the absence of anti-sulfur coating in the ERJ-14NF variant; however, both parts satisfy AEC-Q200 automotive requirements and identical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F2702U is the preferred selection for new designs due to its active production status and anti-sulfur coating feature, which provides enhanced reliability in corrosive environments.

The ERJ-14NF2702U is electrically and mechanically equivalent and remains suitable for existing designs, maintenance applications, or situations where supply of the primary part is constrained. The "Not For New Designs" designation reflects Panasonic's product lifecycle management rather than performance limitations. Both parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance.

Selection between these parts should be based on design phase (new vs. existing), supply availability, and environmental exposure requirements. Both parts are interchangeable at the circuit level when electrical specifications and package dimensions are the controlling factors.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2702U be used as a direct replacement for ERJ-S14F2702U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across identical temperature ranges (-55°C ~ 155°C), and maintain the same electrical specifications (27 kOhms ±1%, 0.5W). The primary difference is the anti-sulfur coating present in the ERJ-S14F2702U. For applications where sulfur exposure is not a concern, the ERJ-14NF2702U provides full functional equivalence.

Q: Why is ERJ-14NF2702U marked "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this part to end-of-life status and recommends the ERJ-S14F2702U for new product development. However, the part remains available and fully functional for existing designs and replacement applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both 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 of 0.028" (0.70mm). They are mechanically interchangeable on PCBs designed for either part.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both ERJ-S14F2702U and ERJ-14NF2702U carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of the anti-sulfur coating in the ERJ-S14F2702U?

A: The anti-sulfur coating provides protection against sulfur-containing contaminants in the environment, which can degrade component performance over time. This feature is particularly valuable in industrial and automotive applications with potential exposure to sulfur compounds. The ERJ-14NF2702U lacks this coating but remains suitable for controlled environments.
