Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ430 is determined by the following critical parameters:

• Resistance value: 43 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Package type: 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 Qualification: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ERJ-PA3J430V qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The power rating difference (0.333W vs 0.25W) represents a higher capability and does not restrict substitution in applications designed for the original 0.25W specification.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-PA3J430V from Panasonic Electronic Components is a qualified direct substitute for the ESR03EZPJ430. Both components maintain identical electrical specifications, package dimensions, and automotive compliance certifications. The substitute part carries AEC-Q200 qualification and ROHS3 compliance, meeting all regulatory and quality requirements of the original specification.

The higher power rating of the ERJ-PA3J430V (0.333W versus 0.25W) provides additional thermal margin in applications and does not introduce compatibility issues when substituting into designs specified for the original 0.25W component. Both parts are actively produced and widely available through authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-PA3J430V replace the ESR03EZPJ430 in automotive applications?

A: Yes. Both components carry AEC-Q200 qualification and are designed for automotive use. All critical electrical parameters, package dimensions, and operating temperature ranges are identical.

Q: Does the higher power rating of the ERJ-PA3J430V affect compatibility?

A: No. A higher power rating does not restrict substitution. The ERJ-PA3J430V can safely operate in any application designed for the 0.25W ESR03EZPJ430 without performance degradation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 0603 (1608 Metric) package with identical length (0.063"), width (0.031"), and maximum seated height (0.022"). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ESR03EZPJ430 and ERJ-PA3J430V are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited).

Q: What is the temperature coefficient specification for both parts?

A: Both components have a temperature coefficient of ±200ppm/°C and operate across the identical temperature range of -55°C to 155°C.
