Substitute Part Grouping Explanation

Substitution of the ESR03EZPJ164 is permissible with the ERJ-PA3J164V based on the following criteria:

Matching Parameters (Substitution Basis):

• Resistance value: 160 kOhms
• Tolerance: ±5%
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• Pulse Withstanding capability
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: The substitute part (ERJ-PA3J164V) is rated at 0.333W (1/3W), which exceeds the original 0.25W (1/4W) specification. Higher power ratings are acceptable substitutes as they provide equal or greater thermal dissipation capability within the same physical package.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-PA3J164V from Panasonic Electronic Components is a direct substitute for the ESR03EZPJ164 from Rohm Semiconductor. Both components maintain active product status and carry identical AEC-Q200 automotive qualification. The substitute part provides a higher power rating (0.333W versus 0.25W) within the same 0603 package footprint, which presents no compatibility issues for circuit design. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1). Selection between these parts should be based on availability, lead time, and supply chain requirements, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J164V replace ESR03EZPJ164 in existing designs? A: Yes. The substitute part is electrically and mechanically compatible. Identical resistance, tolerance, temperature coefficient, and operating temperature range ensure functional equivalence. The higher power rating of the substitute part does not create compatibility issues.

Q: Does the higher power rating (0.333W vs 0.25W) affect circuit performance? A: No. A higher power rating indicates greater thermal dissipation capability. The substitute part will perform identically to the original specification in all circuit applications designed for 0.25W operation.

Q: Are both parts suitable for automotive applications? A: Yes. Both ESR03EZPJ164 and ERJ-PA3J164V carry AEC-Q200 qualification and pulse withstanding capability, meeting automotive reliability standards.

Q: Is the 0603 package footprint identical between both parts? 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 (0.022" / 0.55mm). PCB layout and assembly processes require no modification.

Q: What is the difference in inventory availability? A: ESR03EZPJ164 has 704 units in stock, while ERJ-PA3J164V has 1978 units available. The substitute part offers greater supply availability.

Q: Are both parts RoHS compliant? A: Yes. Both components are ROHS3 compliant and carry identical moisture sensitivity level (MSL 1 - Unlimited), meeting environmental and regulatory requirements.
