ESR10EZPJ303 Equivalent & Substitute Parts

Part Overview

The ESR10EZPJ303 is a 30 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 0805 (2012 Metric) package. This component is rated for 0.4W power dissipation and meets automotive AEC-Q200 qualification with pulse withstanding capability. The part is currently in active production status with 938 units available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits higher-rated alternatives that maintain electrical and mechanical compatibility within the same package footprint.

Substitute Part Grouping Explanation

Substitution of the ESR10EZPJ303 with the ERJ-P06J303V is permissible based on the following alignment of critical parameters:

• Resistance Value: Both parts are 30 kOhms with ±5% tolerance
• Package Footprint: Both use 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm)
• Composition & Features: Both are thick film resistors with AEC-Q200 automotive qualification and pulse withstanding capability
• Temperature Coefficient: Both specify ±200ppm/°C
• Operating Temperature Range: Both rated -55°C ~ 155°C
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited)

The ERJ-P06J303V provides a higher power rating (0.5W vs. 0.4W), which represents an upgrade path for applications requiring additional thermal margin without changing the electrical or mechanical interface.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-P06J303V qualifies as a direct substitute for the ESR10EZPJ303 in applications where the following conditions are met:

• PCB layout accommodates the maximum seated height of 0.028" (0.70mm) for the substitute part
• Circuit design does not impose restrictions on power dissipation capability above 0.4W
• Procurement prioritizes component availability and supply chain resilience

Both parts maintain identical electrical performance within the specified tolerance and temperature operating range. Both carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are preserved across the substitution.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-P06J303V be used as a direct replacement for the ESR10EZPJ303 on existing PCBs?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical land pattern dimensions. The maximum seated height difference (0.028" vs. 0.026") is negligible for standard PCB assembly processes and does not affect mechanical clearance in typical applications.

Q: What is the primary difference between these two parts?

A: The ERJ-P06J303V has a higher power rating (0.5W vs. 0.4W). All other electrical parameters—resistance, tolerance, temperature coefficient, and operating temperature range—are identical. This makes the Panasonic part suitable for applications requiring additional thermal margin.

Q: Are both parts automotive qualified?

A: Yes. Both the ESR10EZPJ303 and ERJ-P06J303V carry AEC-Q200 automotive qualification and meet ROHS3 compliance requirements.

Q: Does the higher power rating of the ERJ-P06J303V affect circuit performance?

A: No. Power rating is a thermal specification that defines the maximum power the resistor can safely dissipate. A higher rating does not change the electrical behavior of the component in the circuit. The resistance value, tolerance, and temperature coefficient remain identical.

Q: Are there any package or footprint considerations when substituting?

A: Both parts use the 0805 (2012 Metric) package with identical land pattern dimensions (2.00mm x 1.25mm). The seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not require design changes.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
