ERJ-S14J182U Equivalent & Substitute Parts

Part Overview

The ERJ-S14J182U is a 1.8 kOhms ±5% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is currently in active product status with 1111 pieces in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative feature sets such as pulse withstanding capability, or when sourcing from alternative manufacturers is required for supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14J182U is determined by the following parameters:

Resistance value: 1.8 kOhms
Tolerance: ±5%
Power rating: 0.5W (1/2W)
Package: 1210 (3225 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C ~ 155°C
Automotive rating: AEC-Q200
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1

All substitute parts listed meet these core electrical and mechanical parameters. Variations exist in product status, feature enhancements (such as pulse withstanding capability), and manufacturer identity. Physical dimensions remain consistent across all listed substitutes with minor variations in maximum seated height.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S14J182U, ERJ-P14J182U, ERJ-T14J182U, or CRCW12101K80JNEA. All four parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

ERJ-P14J182U and ERJ-T14J182U offer pulse withstanding capability as an enhanced feature over the base ERJ-S14J182U specification. This feature provides additional robustness in applications subject to transient voltage events.

CRCW12101K80JNEA from Vishay Dale provides cross-manufacturer equivalence with identical electrical parameters and automotive certification. This option supports supply chain diversification.

ERJ-14YJ182U carries a "Not For New Designs" status and should be used only in legacy design maintenance or when existing inventory must be consumed in production continuation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J182U or ERJ-T14J182U be used as direct replacements for ERJ-S14J182U?

A: Yes. Both parts meet all core electrical and mechanical parameters: 1.8 kOhms ±5%, 0.5W power rating, 1210 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive rating. The pulse withstanding feature is an enhancement that does not affect compatibility in standard applications.

Q: What is the difference between ERJ-S14J182U and ERJ-14YJ182U?

A: Both parts are electrically and mechanically identical. The primary difference is product status: ERJ-S14J182U is Active, while ERJ-14YJ182U is marked "Not For New Designs." ERJ-14YJ182U should not be selected for new product development.

Q: Can CRCW12101K80JNEA from Vishay Dale replace the Panasonic ERJ-S14J182U?

A: Yes. The Vishay Dale CRCW12101K80JNEA meets all specified electrical parameters, package requirements, and automotive certifications. The maximum seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the Panasonic part, which is a favorable variation for PCB assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part has the highest inventory availability?

A: ERJ-14YJ182U has the highest inventory at 15,733 pieces. However, due to its "Not For New Designs" status, ERJ-P14J182U (14,195 pieces) is the recommended high-availability alternative for active designs.
