ESR25JZPJ301 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ301 is a 300 Ohms ±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 with 1085 units in stock. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESR25JZPJ301 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 300 Ohms
• Tolerance: ±5%
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Number of terminations: 2

Compliance & Ratings (Must Match):

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1

Power Rating Consideration: The ESR25JZPJ301 is rated at 0.667W (2/3W). Substitute parts rated at 0.5W (1/2W) are electrically compatible and mechanically interchangeable within the same package footprint. The lower power rating of substitute parts does not affect compatibility in applications where the original 0.667W rating is not fully utilized.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

ERJ-P14J301U (Panasonic Electronic Components) and RMCF1210JT300R (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain active product status, full AEC-Q200 automotive qualification, ROHS3 compliance, and identical electrical specifications. These parts are suitable for new designs and ongoing production applications.

CRCW1210300RJNEA (Vishay Dale) is also an active product with equivalent specifications and qualifications, offering an additional sourcing option.

Secondary Substitute (Legacy Status):

ERJ-14YJ301U (Panasonic Electronic Components) is designated "Not For New Designs" and should be used only for replacement or repair of existing assemblies where continuity with legacy components is required.

Power Rating Consideration:

All substitute parts are rated at 0.5W (1/2W), compared to the original 0.667W (2/3W) rating of the ESR25JZPJ301. This lower rating is acceptable for applications where the actual power dissipation does not exceed 0.5W. Circuit design review is necessary to confirm power dissipation requirements before substitution.

Height Variation:

Substitute parts exhibit minor height variations (0.024" to 0.028" seated height) compared to the original 0.026". These variations remain within typical PCB assembly tolerances and do not affect mechanical compatibility in standard 1210 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J301U replace ESR25JZPJ301 in automotive applications?

A: Yes. ERJ-P14J301U maintains identical electrical specifications (300 Ohms ±5%, ±200ppm/°C, -55°C to 155°C), AEC-Q200 automotive qualification, and 1210 package compatibility. The lower 0.5W power rating is acceptable if circuit power dissipation does not exceed this limit.

Q: What is the difference between the 0.667W and 0.5W power ratings?

A: The ESR25JZPJ301 is rated for 0.667W continuous power dissipation, while substitute parts are rated for 0.5W. Substitution is valid only when actual circuit power dissipation remains below 0.5W. Applications requiring the full 0.667W rating must use the original part or equivalent higher-power alternatives.

Q: Are all substitute parts suitable for new designs?

A: ERJ-P14J301U, CRCW1210300RJNEA, and RMCF1210JT300R are active products suitable for new designs. ERJ-14YJ301U is marked "Not For New Designs" and should be reserved for legacy system support only.

Q: Do the height variations of substitute parts affect PCB assembly?

A: No. Height variations (0.024" to 0.028") are within standard PCB assembly tolerances for 1210 package components and do not affect placement, soldering, or mechanical fit.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original ESR25JZPJ301 specifications.

Q: Which substitute offers the best inventory availability?

A: ERJ-14YJ301U (Panasonic) has the highest inventory at 91,128 units. RMCF1210JT300R (Stackpole) offers 28,918 units, and ERJ-P14J301U (Panasonic) has 22,130 units. CRCW1210300RJNEA (Vishay Dale) has 5,158 units available.
