ESR25JZPJ302 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ302 is a 3 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package with 0.667W power rating. This component is rated for automotive applications under AEC-Q200 and features pulse withstanding capability. The part is currently in active production status with 1726 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ302 is determined by the following critical parameters:

• Resistance value: 3 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package type: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The identified substitute parts meet all these criteria. Power rating variations are acceptable within the constraints of the 1210 package footprint, provided the substitute part power rating is sufficient for the application circuit requirements.

Engineering Selection Recommendations

CRCW12103K00JNEA (Vishay Dale) is the primary substitute for new designs. This part maintains active production status, meets all electrical and mechanical specifications, and provides the highest inventory availability at 22,102 units. The reduced power rating of 0.5W versus the original 0.667W is acceptable provided circuit analysis confirms the application does not require the higher power dissipation capability.

ERJ-14YJ302U (Panasonic Electronic Components) is available as a secondary substitute with 50,681 units in stock. However, this part carries a "Not For New Designs" status, making it suitable only for legacy system maintenance or replacement applications where design changes are not feasible.

Frequently Asked Questions (FAQ)

Q: Can CRCW12103K00JNEA replace ESR25JZPJ302 in all applications?

A: CRCW12103K00JNEA is electrically and mechanically compatible with ESR25JZPJ302 for applications where the circuit power dissipation does not exceed 0.5W at the 3 kOhm resistance value. Circuit analysis is required to confirm power requirements.

Q: What is the significance of the power rating difference?

A: The ESR25JZPJ302 is rated for 0.667W while CRCW12103K00JNEA is rated for 0.5W. Both parts use the same 1210 package footprint. The substitute part has a lower power dissipation capability. Applications must not exceed 0.5W continuous power dissipation when using the substitute.

Q: Why is ERJ-14YJ302U marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. It remains available for existing product support and legacy system maintenance but should not be selected for new circuit designs.

Q: Are all substitute parts PCB footprint compatible?

A: Yes. All parts use the 1210 (3225 Metric) package with identical length and width dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm). Height variations are minimal (0.024" to 0.028") and do not affect standard PCB assembly processes.

Q: Do substitute parts maintain automotive AEC-Q200 compliance?

A: Yes. Both CRCW12103K00JNEA and ERJ-14YJ302U carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.
