ESR25JZPJ270 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ270 is a 27 Ohm ±5% thick film chip resistor rated at 0.667W (2/3W) in a 1210 (3225 Metric) surface mount package. Manufactured by Rohm Semiconductor, this component meets automotive AEC-Q200 qualification and features pulse withstanding capability. The part is currently active in production with 2534 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements allow for alternative manufacturers meeting identical electrical and mechanical specifications. The ESR25JZPJ270 has documented equivalents from Panasonic Electronic Components, Vishay Dale, and Stackpole Electronics Inc that maintain compatibility across key parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ270 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 Ohms
• Tolerance: ±5%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation: Power rating may vary within the following constraints: substitute parts rated at 0.5W (1/2W) or 0.75W (3/4W) are acceptable as these ratings exceed or match the minimum power dissipation requirements of the original 0.667W (2/3W) specification. Physical height variation resulting from different power ratings remains within acceptable assembly tolerances for the 1210 package footprint.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the ESR25JZPJ270 across the critical parameters that determine functional equivalence. Selection among available substitutes should be based on the following criteria:

For Active Production Designs: ERJ-P14J270U, CRCW121027R0JNEA, CRCW121027R0JNEAHP, and RMCF1210JT27R0 are all designated as Active products and are suitable for new design implementations. These parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance status.

For Designs Requiring Enhanced Power Dissipation: CRCW121027R0JNEAHP offers a 0.75W (3/4W) power rating, providing additional thermal margin compared to the original 0.667W (2/3W) specification. This part maintains all other electrical parameters and package dimensions within acceptable assembly tolerances.

For Legacy Design Support: ERJ-14YJ270U carries a "Not For New Designs" product status designation. This part remains electrically and mechanically equivalent but should not be selected for new production designs. It is suitable only for sustaining production of existing designs where component continuity is required.

Inventory Availability: CRCW121027R0JNEA (10,581 units), CRCW121027R0JNEAHP (11,754 units), and RMCF1210JT27R0 (10,669 units) offer substantial stock levels. ERJ-P14J270U provides the highest inventory availability at 20,362 units.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 0.5W (1/2W) rated resistor for the original 0.667W (2/3W) part?

A: No. The original ESR25JZPJ270 is rated at 0.667W (2/3W). Substitute parts must be rated at equal or higher power dissipation. Parts rated at 0.5W (1/2W) fall below the original specification and are not acceptable substitutes. Only CRCW121027R0JNEAHP at 0.75W (3/4W) provides adequate power rating elevation.

Q: What is the significance of the "Not For New Designs" status on ERJ-14YJ270U?

A: This designation indicates the part is in mature production phase with no active development or enhancement. While electrically and mechanically equivalent, it should not be selected for new product designs. It remains available for sustaining production of existing designs only.

Q: Are all substitute parts qualified to the same automotive standard?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification identical to the ESR25JZPJ270. All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does the height variation between substitute parts affect PCB assembly?

A: The ESR25JZPJ270 has a maximum seated height of 0.026" (0.65mm). Substitute parts range from 0.024" (0.60mm) to 0.028" (0.70mm). These variations remain within standard 1210 package assembly tolerances and do not require PCB layout modifications.

Q: Can I use CRCW121027R0JNEAHP as a direct replacement in all applications?

A: CRCW121027R0JNEAHP is electrically and mechanically equivalent with the exception of its higher 0.75W (3/4W) power rating. This elevated rating provides additional thermal margin and is acceptable in all applications where the original 0.667W (2/3W) part was specified. No circuit redesign is required.

Q: Which substitute part offers the best long-term availability?

A: ERJ-P14J270U from Panasonic Electronic Components currently maintains the highest inventory level at 20,362 units. All listed Active status parts (ERJ-P14J270U, CRCW121027R0JNEA, CRCW121027R0JNEAHP, RMCF1210JT27R0) are suitable for long-term production use.
