ERJ-S14F9310U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F9310U is a 931 Ohm ±1% thick film chip resistor rated at 0.5W (1/2W) in a 1210 (3225 Metric) package. This component is manufactured by Panasonic Electronic Components and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 643 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit the use of functionally equivalent alternatives from the same or different manufacturers. The ERJ-S14F9310U has one direct substitute available: ERJ-14NF9310U, which shares identical electrical specifications but differs in product lifecycle status and anti-sulfur feature availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9310U is determined by strict equivalence across the following critical parameters:

• Resistance value: 931 Ohms
• 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-14NF9310U meets all these criteria and is classified as a direct substitute. This part maintains identical electrical and mechanical specifications, with the primary distinction being its product lifecycle status (Not For New Designs) and the absence of anti-sulfur protection compared to the ERJ-S14F9310U.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9310U is the preferred choice for new designs due to its active product status and anti-sulfur protection feature, which provides enhanced reliability in harsh automotive environments. The ERJ-14NF9310U serves as a functional equivalent for applications where anti-sulfur protection is not a design requirement and where the higher available inventory (12,569 units) addresses supply chain needs.

Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for automotive circuit applications. Selection between these parts should be based on design specifications regarding sulfur resistance requirements and product lifecycle considerations for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9310U be used as a direct replacement for ERJ-S14F9310U in automotive applications?

A: Yes, the ERJ-14NF9310U is electrically and mechanically equivalent to the ERJ-S14F9310U. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. The primary difference is the absence of anti-sulfur protection in the ERJ-14NF9310U and its Not For New Designs status.

Q: What is the significance of the anti-sulfur feature in the ERJ-S14F9310U?

A: The anti-sulfur protection in the ERJ-S14F9310U provides enhanced resistance to sulfur-containing environments, which can occur in certain automotive and industrial applications. This feature is not present in the ERJ-14NF9310U.

Q: Are both parts suitable for the same temperature range?

A: Yes, both the ERJ-S14F9310U and ERJ-14NF9310U operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C.

Q: What does "Not For New Designs" mean for the ERJ-14NF9310U?

A: This status indicates that while the ERJ-14NF9310U remains available and functional, Panasonic recommends using the ERJ-S14F9310U for new product designs. The substitute part may have limited long-term availability or support.

Q: Do both parts meet automotive qualification standards?

A: Yes, both the ERJ-S14F9310U and ERJ-14NF9310U carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry reliability and environmental standards.

Q: Is the 1210 package compatible with standard PCB assembly equipment?

A: Yes, the 1210 (3225 Metric) package is a standard surface-mount package size compatible with conventional PCB assembly equipment and processes.
