ERJ-S14F9530U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F9530U is a 953 Ohm ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and AEC-Q200 automotive qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9530U is determined by strict equivalence across the following parameters:

• Resistance value: 953 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF9530U meets all electrical and mechanical requirements for direct substitution. While the ERJ-14N series is designated as "Not For New Designs," it remains electrically and mechanically equivalent and is suitable for replacement applications where existing inventory or supply availability justifies its use.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9530U is the preferred selection for new designs due to its active production status and anti-sulfur feature. The ERJ-14NF9530U provides electrical and mechanical equivalence and is suitable for replacement or retrofit applications where supply of the primary part is constrained.

Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting the same regulatory and reliability standards. Selection between these parts should be based on availability, lead time requirements, and design phase considerations rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9530U be used as a direct replacement for ERJ-S14F9530U?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, temperature coefficient, and operating temperature range. Both carry AEC-Q200 qualification and ROHS3 compliance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9530U?

A: This designation indicates the ERJ-14N series is in mature production phase with no planned enhancements. It remains fully functional and qualified for use in replacement or retrofit applications. New designs should prioritize the ERJ-S14F9530U (active status) for long-term supply assurance.

Q: Are there package compatibility concerns 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 (0.028", 0.70mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet automotive standards?

A: Yes. Both the ERJ-S14F9530U and ERJ-14NF9530U carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

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

A: The ERJ-S14 series represents the current generation with active production status and anti-sulfur coating. The ERJ-14N series is a previous generation maintained in production for replacement applications. Both series meet identical electrical specifications for the 953 Ohm ±1% 0.5W 1210 package configuration.
