ESR25JZPJ274 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ274 is a 270 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 1107 units available in stock.

Substitute parts are necessary when the primary component becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified manufacturers is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ274 is determined by the following critical parameters:

• Resistance value: 270 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package: 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 substitute parts listed below meet all these criteria. Power rating variations are permitted when the substitute part maintains equal or greater power handling capability within the same package footprint, as the electrical performance and thermal characteristics remain compatible with the original design intent.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210270KJNEA (Vishay Dale) is the primary substitute for new designs. This part maintains active production status, meets all electrical and mechanical specifications, and provides equivalent AEC-Q200 automotive qualification. The reduced power rating (0.5W versus 0.667W) is acceptable for applications where the original design margin permits, as both parts share identical package dimensions and thermal characteristics within the 1210 footprint.

ERJ-14YJ274U (Panasonic Electronic Components) is available as a secondary substitute but carries a "Not For New Designs" status. This designation indicates the manufacturer is phasing out this product line. Use of this part should be limited to legacy design support or situations where existing inventory must be maintained. The slightly increased seated height (0.028" versus 0.026") remains within acceptable PCB assembly tolerances for the 1210 package.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210270KJNEA be used as a direct replacement for ESR25JZPJ274?

A: Yes. Both parts share identical resistance (270 kOhms), tolerance (±5%), package (1210), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive rating. The power rating difference (0.5W versus 0.667W) does not prevent substitution when circuit design margins accommodate the lower rating.

Q: What is the significance of the "Not For New Designs" status on ERJ-14YJ274U?

A: This status indicates Panasonic has discontinued active development and is transitioning away from this product line. While the part remains functionally equivalent and available in current inventory (9103 units), it should not be selected for new product designs. Existing designs using this part may continue to source it during the transition period, but long-term availability is not guaranteed.

Q: Are there physical compatibility concerns between these substitute parts?

A: All three parts use the 1210 (3225 Metric) package with identical length and width dimensions (0.126" x 0.098"). Seated heights vary slightly: ESR25JZPJ274 at 0.026", CRCW1210270KJNEA at 0.024", and ERJ-14YJ274U at 0.028". These variations fall within standard PCB assembly tolerances and do not create compatibility issues.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, carry MSL 1 (unlimited moisture sensitivity level), and hold AEC-Q200 automotive qualification. Regulatory and environmental compliance is equivalent across all options.

Q: What should guide the selection between CRCW1210270KJNEA and ERJ-14YJ274U?

A: For new designs, select CRCW1210270KJNEA due to its active production status and long-term availability assurance. For legacy design support or when existing Panasonic inventory must be utilized, ERJ-14YJ274U remains functionally qualified despite its discontinued status.
