ERJ-S14F9761U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F9761U is a 9.76 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 product status with 1067 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components from alternative product series. The ERJ-14NF9761U represents a functionally equivalent alternative from Panasonic's automotive-grade resistor portfolio, though it carries a "Not For New Designs" status designation.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9761U is determined by strict equivalence across the following parameters:

• Resistance value: 9.76 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package format: 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)

The ERJ-14NF9761U from Panasonic Electronic Components meets all electrical and mechanical parameters specified above. This part is classified as a direct functional equivalent despite its "Not For New Designs" status, which reflects manufacturing lifecycle positioning rather than technical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9761U is the preferred selection for new designs due to its Active product status and ongoing manufacturing support from Panasonic Electronic Components. This part carries full automotive AEC-Q200 qualification and anti-sulfur protection, making it suitable for harsh automotive environments.

The ERJ-14NF9761U serves as a functional equivalent for applications requiring component replacement or inventory supplementation. Although designated "Not For New Designs," this part maintains identical electrical specifications, mechanical compatibility, and compliance certifications. Selection of the substitute should be based on availability constraints or design revision requirements rather than technical performance differences.

Both parts comply with ROHS3 regulations, carry unlimited moisture sensitivity rating (MSL 1), and operate across the full -55°C to 155°C temperature range. Substitution between these parts does not require circuit redesign or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9761U be used as a direct replacement for ERJ-S14F9761U in existing designs?

A: Yes. Both parts share identical resistance value (9.76 kOhms), tolerance (±1%), power rating (0.5W), package format (1210), and AEC-Q200 automotive qualification. Electrical and mechanical compatibility is complete.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9761U?

A: This designation indicates the part is in the mature or declining phase of its product lifecycle. Panasonic continues to manufacture and support this component, but recommends the ERJ-S14F9761U for new product development. Existing applications using ERJ-14NF9761U may continue without modification.

Q: Are there differences in anti-sulfur protection between these parts?

A: The ERJ-S14F9761U explicitly includes anti-sulfur protection in its specification. The ERJ-14NF9761U specification does not list this feature. For applications in high-sulfur environments, the ERJ-S14F9761U is the specified choice.

Q: Do both parts meet the same temperature coefficient specification?

A: Yes. Both parts maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range, ensuring equivalent frequency stability and thermal performance.

Q: Is the 1210 package footprint identical between both 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). PCB layout and assembly processes require no modification.

Q: Which part should be selected for automotive applications?

A: Both parts carry AEC-Q200 automotive qualification and are suitable for automotive use. The ERJ-S14F9761U is recommended for new automotive designs. The ERJ-14NF9761U may be used for production continuity or replacement scenarios in existing automotive applications.
