ESR25JZPJ240 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ240 is a 24 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. Rated for 0.667W (2/3W) power dissipation with automotive AEC-Q200 qualification and pulse withstanding capability, this component operates across -55°C to 155°C. The part is currently active in production. Substitute parts may be required due to inventory constraints, manufacturing discontinuation of specific series, or design optimization for alternative performance characteristics within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (24 Ohms), tolerance (±5%), package type (1210 / 3225 Metric), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 compliance. Power rating represents a critical design parameter; substitute parts rated at 0.5W (1/2W) are electrically compatible but operate at reduced thermal margin compared to the 0.667W (2/3W) main part. All substitute candidates maintain identical electrical performance within the specified tolerance and temperature range while meeting the same automotive qualification standard.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-P14J240U (Panasonic), CRCW121024R0JNEA (Vishay Dale), or RMCF1210JT24R0 (Stackpole Electronics Inc). All three maintain full electrical equivalence to the ESR25JZPJ240 and carry AEC-Q200 automotive qualification with ROHS3 compliance. The ERJ-14YJ240U carries a "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where design continuity is required.

Power rating differences (0.5W versus 0.667W) do not affect electrical compatibility but impact thermal performance in high-dissipation applications. The CRCW121024R0JNEA offers the lowest seated height (0.024"), which may provide advantages in space-constrained PCB layouts. All substitute parts are qualified to the same temperature range and maintain identical resistance tolerance and temperature coefficient specifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J240U, CRCW121024R0JNEA, RMCF1210JT24R0, and ERJ-14YJ240U be used interchangeably with ESR25JZPJ240?

A: Yes, all four parts are electrically equivalent. They share identical resistance (24 Ohms), tolerance (±5%), package (1210), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). All carry AEC-Q200 automotive qualification. The primary difference is power rating: the main part is rated 0.667W while the substitutes are rated 0.5W. In applications where thermal margin is not critical, the lower power-rated parts function identically.

Q: What is the significance of the power rating difference between 0.667W and 0.5W?

A: Power rating indicates maximum continuous power dissipation before thermal damage occurs. The 0.5W-rated substitutes have lower thermal capacity than the 0.667W main part. In circuits where resistor power dissipation remains below 0.5W, this difference is not operationally significant. For applications approaching or exceeding 0.5W dissipation, the 0.667W main part provides additional thermal margin.

Q: Why is ERJ-14YJ240U marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. It remains available for existing inventory and legacy system support. For new designs, select from the three Active-status alternatives: ERJ-P14J240U, CRCW121024R0JNEA, or RMCF1210JT24R0.

Q: Are there package or height considerations when substituting these parts?

A: All parts use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm). Seated height varies slightly: ESR25JZPJ240 (0.026"), CRCW121024R0JNEA (0.024"), ERJ-P14J240U and ERJ-14YJ240U (0.028"), and RMCF1210JT24R0 (0.028"). These height variations are within typical PCB assembly tolerances and do not affect mechanical compatibility or solderability.

Q: Do all substitute parts meet automotive and compliance requirements?

A: Yes. All parts listed carry AEC-Q200 automotive qualification, ROHS3 compliance, and REACH Unaffected status. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
