Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ624 is determined by the following critical parameters:

• Resistance value: 620 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package: 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 or better required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ERJ-PA3J624V from Panasonic Electronic Components meets all substitution criteria. While the power rating differs (0.333W vs 0.25W), the higher power rating of the substitute part provides equivalent or superior performance in applications designed for the original 0.25W specification, maintaining full compatibility with circuit requirements and thermal management constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ624 and ERJ-PA3J624V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability and supply chain requirements. The Panasonic ERJ-PA3J624V offers higher inventory availability (5180 units vs 688 units) and increased power dissipation capability (0.333W vs 0.25W) while maintaining identical electrical specifications, package dimensions, and environmental ratings. Both components are suitable for direct substitution in automotive and industrial applications requiring 620 kOhms ±5% thick film resistors in 0603 package format.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J624V replace ESR03EZPJ624 in existing designs?

A: Yes. The ERJ-PA3J624V is a direct substitute. Both parts share identical resistance (620 kOhms), tolerance (±5%), package (0603), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The higher power rating (0.333W vs 0.25W) of the substitute part does not create compatibility issues in circuits designed for 0.25W operation.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0603 (1608 Metric) package with identical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet automotive standards?

A: Yes. Both ESR03EZPJ624 and ERJ-PA3J624V carry AEC-Q200 qualification and are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting automotive and industrial reliability requirements.

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

A: The ERJ-PA3J624V power rating of 0.333W (1/3W) exceeds the ESR03EZPJ624 specification of 0.25W (1/4W). In applications designed for the lower power rating, the substitute part will operate at lower thermal stress, improving reliability and component lifespan without affecting electrical performance.

Q: Are temperature coefficients identical?

A: Yes. Both parts specify ±200ppm/°C temperature coefficient and operate across the identical temperature range of -55°C ~ 155°C, ensuring equivalent frequency stability and thermal performance characteristics.
