ERJ-S14F3573U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F3573U is a 357 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part is classified as Active product status and features anti-sulfur coating with AEC-Q200 automotive qualification. Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward alternative feature sets, or when inventory constraints require sourcing from alternative product lines within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F3573U is determined by strict equivalence across the following parameters: resistance value (357 kOhms), tolerance (±1%), power rating (0.5W), package type (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. All substitute parts listed maintain these core electrical and mechanical specifications. Differences in product status, feature enhancements (such as pulse withstanding capability), or series designation do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S14F3573U is the primary selection for new designs due to its Active product status and anti-sulfur feature set. ERJ-P14F3573U serves as the preferred substitute when pulse withstanding capability is required within the same electrical specification envelope; this part maintains Active status and full AEC-Q200 compliance. ERJ-14NF3573U is available as a secondary option with equivalent electrical and mechanical parameters but carries Not For New Designs status, making it suitable only for legacy system maintenance or replacement scenarios where design continuity is the priority.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F3573U replace ERJ-S14F3573U in automotive applications? A: Yes. Both parts meet identical electrical specifications (357 kOhms ±1%, 0.5W, ±100ppm/°C), operate across the same temperature range (-55°C ~ 155°C), are packaged in 1210 (3225 Metric), and carry AEC-Q200 automotive qualification. The pulse withstanding feature of ERJ-P14F3573U does not affect standard circuit operation.

Q: Why is ERJ-14NF3573U marked "Not For New Designs"? A: Product status reflects Panasonic's lifecycle management. ERJ-14NF3573U maintains full electrical and mechanical equivalence but is reserved for legacy system support. New designs should prioritize ERJ-S14F3573U or ERJ-P14F3573U.

Q: Are all three parts pin-compatible? A: Yes. All three parts use identical 1210 (3225 Metric) package with two terminations, 0.126" L x 0.098" W (3.20mm x 2.50mm) dimensions, and 0.028" (0.70mm) maximum seated height.

Q: What is the significance of anti-sulfur coating on ERJ-S14F3573U? A: Anti-sulfur coating protects the resistor element from sulfur-containing environmental contaminants. This feature is specified in the ERJ-S14F3573U but not listed for ERJ-14NF3573U or ERJ-P14F3573U. Selection should account for application environment requirements.

Q: Do all substitute parts comply with RoHS and REACH regulations? A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental compliance standards.
