ERJ-S14F3163U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F3163U is a 316 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 1113 units available in stock.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F3163U is determined by strict equivalence across the following critical parameters:

• Resistance value: 316 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-14NF3163U meets all substitution criteria and is qualified as a direct equivalent. While the ERJ-14NF3163U carries a "Not For New Designs" status, it remains electrically and mechanically interchangeable with the primary part for existing applications and maintenance scenarios.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F3163U is the preferred selection for new designs due to its active production status and anti-sulfur feature set. The ERJ-14NF3163U serves as a qualified substitute for existing applications, maintenance, and repair scenarios where supply of the primary part is unavailable. Both parts carry identical electrical specifications, mechanical dimensions, and automotive compliance certifications, ensuring direct interchangeability at the circuit level.

For new product development, the ERJ-S14F3163U should be specified. For legacy system support or supply chain contingency, the ERJ-14NF3163U is acceptable provided the application does not require new design qualification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3163U be used as a direct replacement for ERJ-S14F3163U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical parameters (316 kOhms ±1%, 0.5W), and use the same 1210 package. The primary difference is product status; ERJ-14NF3163U is not recommended for new designs but remains fully qualified for existing applications.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF3163U?

A: This designation indicates the manufacturer is transitioning the part to end-of-life. It remains available and fully functional but should not be selected for new product development. Existing designs using this part may continue without modification.

Q: Are there dimensional differences between these parts?

A: No. 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).

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

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

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

A: The series designation reflects different product generations within Panasonic's resistor portfolio. The ERJ-S14 series represents the current active generation, while ERJ-14N represents a previous generation. Electrical and mechanical specifications remain equivalent for the specified part numbers.
