ESR03EZPJ684 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ684 is a 680 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability and 0.25W power dissipation. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical characteristics, mechanical compatibility, and automotive qualification requirements are met across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ684 is determined by the following criteria:

• Resistance value must be 680 kOhms
• Tolerance must be ±5%
• Package must be 0603 (1608 Metric)
• Composition must be thick film
• Temperature coefficient must be ±200ppm/°C
• Operating temperature range must be -55°C ~ 155°C
• Automotive AEC-Q200 qualification is required
• RoHS3 compliance is required

The ERJ-PA3J684V from Panasonic Electronic Components meets all substitution criteria. The primary difference is power rating: the substitute part is rated at 0.333W (1/3W) compared to 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 ESR03EZPJ684, as it provides equal or greater thermal capability within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ684 and ERJ-PA3J684V are active production parts with identical AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on application power dissipation requirements and supply chain availability. The Panasonic ERJ-PA3J684V provides higher power handling capability within the same 0603 package, making it suitable for applications where thermal margin is a consideration. Both parts maintain equivalent electrical performance across the specified operating temperature range and are suitable for direct substitution in automotive circuit designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J684V replace ESR03EZPJ684 in existing designs?

A: Yes. Both parts share identical resistance, tolerance, package, composition, temperature coefficient, and operating temperature range. The higher power rating of the ERJ-PA3J684V (0.333W vs 0.25W) does not restrict compatibility and provides additional thermal capability.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.022", 0.55mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ESR03EZPJ684 and ERJ-PA3J684V carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this standard.

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

A: The power rating indicates maximum continuous power dissipation capability. The ERJ-PA3J684V's higher 0.333W rating provides greater thermal headroom than the ESR03EZPJ684's 0.25W rating. Applications designed for 0.25W operation are fully compatible with the higher-rated substitute part.

Q: Are RoHS and REACH compliance identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.
