Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ155 is determined by the following critical parameters:

Resistance value must be 1.5 MOhms with ±5% tolerance. Package must be 0603 (1608 Metric) to ensure PCB footprint compatibility. Temperature coefficient must be ±200ppm/°C. Operating temperature range must span -55°C ~ 155°C. Automotive AEC-Q200 rating is required. Composition must be thick film. RoHS3 compliance and MSL 1 rating must be maintained.

The substitute part ERJ-PA3J155V from Panasonic Electronic Components meets all these criteria. The power rating differential (0.333W versus 0.25W) represents an upgrade in thermal capability and does not restrict substitution in applications designed for the original 0.25W specification.

Parameter Comparison

Engineering Selection Recommendations

Both ESR03EZPJ155 and ERJ-PA3J155V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on manufacturer availability, supply chain requirements, or design documentation specifications. The ERJ-PA3J155V provides higher power dissipation capability (0.333W versus 0.25W) while maintaining identical electrical performance in all other parameters. Both components are suitable for direct substitution in automotive applications requiring 1.5 MOhms resistance with ±5% tolerance in 0603 package format.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J155V replace ESR03EZPJ155 in existing designs? A: Yes. Both parts share identical resistance, tolerance, temperature coefficient, operating temperature range, package dimensions, and automotive AEC-Q200 rating. The higher power rating of the Panasonic part does not create compatibility issues.

Q: Are there package footprint differences between these parts? A: No. Both components use 0603 (1608 Metric) package with identical dimensions of 0.063" L x 0.031" W and maximum seated height of 0.022" (0.55mm).

Q: Do both parts meet automotive qualification requirements? A: Yes. Both ESR03EZPJ155 and ERJ-PA3J155V carry AEC-Q200 automotive rating and are ROHS3 compliant with MSL 1 moisture sensitivity level.

Q: What is the significance of the power rating difference? A: The ERJ-PA3J155V is rated at 0.333W (1/3W) compared to the ESR03EZPJ155 at 0.25W (1/4W). This represents increased thermal capability and does not restrict use in applications designed for the lower power specification.

Q: Are the temperature coefficients identical? A: Yes. Both parts have a temperature coefficient of ±200ppm/°C and operate across the identical temperature range of -55°C ~ 155°C.
