Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ433 is determined by the following critical parameters:

• Resistance value: 43 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-PA3J433V 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 equal or superior performance in the same physical package and maintains all other critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ433 and ERJ-PA3J433V are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. The ERJ-PA3J433V is suitable as a direct substitute due to identical electrical specifications, package dimensions, and automotive ratings. The increased power dissipation capability (0.333W vs. 0.25W) of the Panasonic part does not create compatibility issues and may provide additional design margin in thermal-constrained applications. Both components maintain identical temperature coefficient and operating temperature range specifications required for automotive environments.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J433V replace ESR03EZPJ433 in production?

A: Yes. The ERJ-PA3J433V meets all critical substitution parameters including resistance value, tolerance, package dimensions, composition, temperature coefficient, operating temperature range, and AEC-Q200 automotive rating.

Q: What is the difference in power rating between these parts?

A: The ESR03EZPJ433 is rated at 0.25W (1/4W) while the ERJ-PA3J433V is rated at 0.333W (1/3W). The higher power rating of the substitute part does not affect compatibility and provides equal or superior thermal performance in the same 0603 package.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C, meeting automotive reliability standards.

Q: Do package dimensions differ between these parts?

A: No. Both parts use the 0603 (1608 Metric) package with identical physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm).

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and identical REACH and ECCN classifications.
