Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ243 is determined by the following critical parameters:

• Resistance value: 24 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 or better required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The ERJ-PA3J243V 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 represents an acceptable over-specification that does not compromise circuit performance or reliability.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ243 and ERJ-PA3J243V are active production components with full AEC-Q200 automotive compliance and ROHS3 certification. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain continuity and manufacturer qualification status
• Cost considerations within procurement parameters
• Existing inventory management protocols

The ERJ-PA3J243V offers higher power dissipation capability (0.333W vs. 0.25W) while maintaining identical electrical and mechanical specifications, making it a direct functional equivalent for circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J243V replace ESR03EZPJ243 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive standards, share identical resistance, tolerance, temperature coefficient, and operating temperature range specifications, and are packaged in the same 0603 (1608 Metric) format with matching physical dimensions.

Q: What is the significance of the different power ratings (0.25W vs. 0.333W)?

A: The ERJ-PA3J243V has a higher power rating, which means it can dissipate more heat without exceeding its maximum operating temperature. This represents an over-specification relative to the ESR03EZPJ243 and does not create compatibility issues in circuit design.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum seated height of 0.022" (0.55mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ESR03EZPJ243 and ERJ-PA3J243V are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

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.
