ERJ-S14F9311U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F9311U is a 9.31 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 807 units available in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components with equivalent electrical and mechanical characteristics. The ERJ-S14F9311U has documented substitute availability within the Panasonic ERJ series and cross-manufacturer alternatives that maintain identical electrical specifications and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9311U is determined by strict equivalence across the following parameters:

• Resistance value: 9.31 kOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF9311U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. This part maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both components are manufactured by Panasonic Electronic Components and share the same AEC-Q200 automotive qualification and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9311U is the preferred selection for new designs due to its Active product status. This designation indicates ongoing manufacturer support, continued production, and long-term availability assurance.

The ERJ-14NF9311U is classified as Not For New Designs, reflecting its transition toward obsolescence within the Panasonic product portfolio. However, this substitute maintains complete electrical and mechanical equivalence with the primary part. Selection of the ERJ-14NF9311U is appropriate for:

• Existing production lines requiring component replenishment
• Design revisions of established products where component qualification has been completed
• Applications where inventory availability takes priority over long-term product lifecycle support

Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. The choice between these two Panasonic variants should be based on product lifecycle requirements and inventory strategy rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF9311U be used as a direct replacement for the ERJ-S14F9311U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and maintain identical electrical specifications, tolerance, power rating, and operating temperature range. The primary distinction is product lifecycle status, not electrical performance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9311U?

A: This designation indicates that Panasonic is transitioning this part toward end-of-life. While the component remains available and fully functional, new product designs should prioritize the Active-status ERJ-S14F9311U to ensure long-term supply chain stability and manufacturer support.

Q: Are the physical dimensions and PCB footprints identical between these two parts?

A: Yes. Both components use the 1210 (3225 Metric) package format 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 footprints are interchangeable.

Q: Do both parts require the same moisture handling procedures?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: What compliance certifications apply to both parts?

A: Both the ERJ-S14F9311U and ERJ-14NF9311U are ROHS3 Compliant and REACH Unaffected. Both carry AEC-Q200 automotive qualification. The ERJ-S14F9311U includes additional anti-sulfur protection.
