ERJ-S14F9763U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F9763U is a 976 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 with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit selection from qualified alternatives meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9763U is determined by strict equivalence across the following parameters:

• Resistance value: 976 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
• Physical dimensions and termination count

The ERJ-14NF9763U qualifies as a direct substitute based on matching all electrical specifications and package requirements. Differences in product status and compliance certifications are noted but do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9763U is the preferred selection for new designs due to active product status and ROHS3 compliance. This part meets current regulatory requirements and benefits from ongoing manufacturer support.

The ERJ-14NF9763U provides electrical and mechanical equivalence and is suitable for legacy system maintenance or replacement applications where RoHS compliance is not a design requirement. This part carries a "Not For New Designs" status, indicating it is maintained for existing applications but not recommended for new product development.

Selection between these parts should be based on compliance requirements of the target application and design phase (new development versus legacy support).

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9763U be used as a direct replacement for ERJ-S14F9763U in new automotive designs?

A: Electrical and mechanical specifications are identical. However, ERJ-14NF9763U carries "Not For New Designs" status and is RoHS non-compliant. For new automotive designs, ERJ-S14F9763U is the specified choice.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum seated height of 0.028" (0.70mm). PCB layout and assembly processes require no modification.

Q: What is the significance of the anti-sulfur feature on ERJ-S14F9763U?

A: The anti-sulfur coating on ERJ-S14F9763U provides enhanced corrosion resistance in harsh environments. ERJ-14NF9763U does not specify this feature.

Q: Do both parts meet AEC-Q200 automotive qualification?

A: Yes. Both ERJ-S14F9763U and ERJ-14NF9763U carry AEC-Q200 qualification, meeting automotive reliability standards for temperature cycling, humidity, and mechanical stress.

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

A: These represent different product generations from Panasonic. ERJ-S14 is the current active series. ERJ-14N is a legacy series maintained for existing applications but not recommended for new designs.
