ESR03EZPJ623 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ623 is a 62 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and meets automotive AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 888 units available in inventory. Substitute parts are identified when equivalent electrical characteristics, mechanical compatibility, and automotive compliance ratings are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ623 is determined by strict equivalence across the following parameters:

• Resistance value: 62 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive compliance: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The ERJ-PA3J623V from Panasonic Electronic Components meets all these criteria. The primary difference is the power rating: the substitute part is rated for 0.333W (1/3W) compared to the main part's 0.25W (1/4W). This represents a higher power capability, which is acceptable in substitution scenarios where the original specification does not require the lower power rating as a limiting factor.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ623 and ERJ-PA3J623V are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. The ERJ-PA3J623V provides equivalent electrical performance with increased power dissipation capability (0.333W versus 0.25W). Selection between these parts should be based on supply chain availability and design margin requirements. The higher power rating of the Panasonic part does not introduce incompatibility with circuits designed for the Rohm specification, as it represents a superset of the original performance envelope.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J623V replace ESR03EZPJ623 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, maintain identical resistance value (62 kOhms), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). The ERJ-PA3J623V has a higher power rating (0.333W vs 0.25W), which does not create compatibility issues.

Q: Are the physical dimensions identical?

A: Yes. 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: What is the significance of the power rating difference?

A: The ERJ-PA3J623V's higher power rating (0.333W) indicates greater thermal dissipation capability. This does not affect electrical performance in circuits designed for the 0.25W specification and provides additional design margin in applications with variable power conditions.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both ESR03EZPJ623 and ERJ-PA3J623V are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and HTSUS code 8533.21.0030.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
