ESR03EZPJ754 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ754 is a 750 kOhms ±5% thick film chip resistor in 0603 (1608 Metric) package rated for 0.25W (1/4W) power dissipation. This component is designed for automotive applications and meets AEC-Q200 qualification with pulse withstanding capability. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

The ERJ-PA3J754V from Panasonic Electronic Components qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 750 kOhms
• Identical tolerance: ±5%
• Identical package: 0603 (1608 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical RoHS compliance: ROHS3
• Identical moisture sensitivity level: MSL 1

The primary difference is the power rating: the substitute part is rated for 0.333W (1/3W) versus the main part's 0.25W (1/4W). This higher power rating in the substitute part does not restrict its use in applications designed for the lower-rated component, as it provides equal or greater thermal capability within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ754 and ERJ-PA3J754V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERJ-PA3J754V is suitable for direct substitution in applications originally designed for the ESR03EZPJ754. The higher power rating of the Panasonic part (0.333W versus 0.25W) provides additional thermal margin without affecting electrical performance or physical compatibility. Both components maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications. Selection between these parts should be based on availability, supply chain requirements, and procurement preferences, as electrical and mechanical performance are equivalent within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J754V replace ESR03EZPJ754 in existing designs?

A: Yes. The ERJ-PA3J754V is electrically and mechanically equivalent. Both parts share identical resistance (750 kOhms), tolerance (±5%), package (0603), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating of the substitute part does not create compatibility issues.

Q: What is the significance of the different power ratings?

A: The ESR03EZPJ754 is rated for 0.25W (1/4W) and the ERJ-PA3J754V for 0.333W (1/3W). In substitution, the higher-rated part can safely replace the lower-rated part without thermal or electrical concerns. Power rating indicates maximum continuous dissipation capability; a higher rating provides additional margin.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ESR03EZPJ754 and ERJ-PA3J754V carry AEC-Q200 qualification, confirming suitability for automotive use. Both are ROHS3 compliant and have MSL 1 (unlimited) moisture sensitivity ratings.

Q: Do these parts have identical physical dimensions?

A: Yes. Both components are packaged in 0603 (1608 Metric) with identical length (0.063" / 1.60mm), width (0.031" / 0.80mm), and maximum seated height (0.022" / 0.55mm). They are footprint-compatible for PCB assembly.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts have a temperature coefficient of ±200ppm/°C, meaning resistance changes by a maximum of 200 parts per million for each degree Celsius change in operating temperature. This specification ensures predictable performance across the -55°C to 155°C operating range.
