Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESR03EZPJ7R5 are qualified based on the following criteria:

Direct Substitutes maintain identical electrical specifications: 7.5 Ohm resistance, ±5% tolerance, 0603 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive rating.

Similar Substitutes share the same resistance value, tolerance, package, composition, temperature coefficient, operating range, and automotive rating, but may differ in power rating or specific application features (such as current sense capability versus pulse withstanding).

All substitute candidates must comply with ROHS3, maintain MSL 1 rating, and be supplied in Tape & Reel packaging to ensure compatibility with automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

ERJ-PA3J7R5V qualifies as a direct substitute for the ESR03EZPJ7R5. Both parts share identical resistance, tolerance, package, composition, temperature coefficient, operating range, and AEC-Q200 rating. The ERJ-PA3J7R5V offers higher power dissipation capability (0.333W versus 0.25W), which provides additional thermal margin in applications where the original specification permits. Both parts maintain ROHS3 compliance and MSL 1 rating. This substitute is suitable for direct replacement in designs where the increased power rating does not create thermal or layout constraints.

ERJ-3BQJ7R5V qualifies as a similar substitute with matching electrical and mechanical parameters. The primary distinction is the application-specific feature designation: current sense capability versus pulse withstanding. Both parts maintain identical resistance, tolerance, package, composition, temperature coefficient, operating range, and AEC-Q200 rating. The ERJ-3BQJ7R5V matches the original 0.25W power rating exactly. Selection of this substitute depends on circuit application requirements and whether current sense or pulse withstanding characteristics are functionally necessary for the design.

All three parts are active products with established supply availability and full automotive compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J7R5V replace ESR03EZPJ7R5 in any application?

A: ERJ-PA3J7R5V is electrically and mechanically compatible with ESR03EZPJ7R5 for applications where the circuit design permits a 0.333W power rating. The higher power rating does not create incompatibility; it provides additional thermal headroom. Both parts are AEC-Q200 rated, share identical resistance and tolerance specifications, and use the same 0603 package. Substitution is valid when the original design does not require the specific pulse withstanding feature designation.

Q: What is the difference between pulse withstanding and current sense features?

A: Pulse withstanding and current sense are application-specific feature designations provided by manufacturers. Both ESR03EZPJ7R5 and ERJ-3BQJ7R5V are thick film 0603 resistors with identical electrical parameters. The feature designation indicates the resistor's optimized performance characteristics for specific circuit applications. Selection between these parts depends on whether the circuit application requires one feature over the other.

Q: Are all three parts suitable for automotive applications?

A: Yes. ESR03EZPJ7R5, ERJ-PA3J7R5V, and ERJ-3BQJ7R5V all carry AEC-Q200 automotive qualification. All three parts comply with ROHS3 environmental standards and maintain MSL 1 moisture sensitivity rating. All are supplied in Tape & Reel packaging suitable for automated assembly in automotive manufacturing environments.

Q: Does the 0603 package dimension differ between manufacturers?

A: No. The 0603 (1608 Metric) package is a standardized industry specification. ESR03EZPJ7R5, ERJ-PA3J7R5V, and ERJ-3BQJ7R5V all conform to identical package dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). All parts have two terminations and are mechanically interchangeable on PCB layouts designed for 0603 resistors.

Q: What is the temperature coefficient significance for these parts?

A: All three parts share ±200ppm/°C temperature coefficient and operate across -55°C to 155°C. This specification indicates the resistor's resistance change per degree Celsius within the operating range. Identical temperature coefficients ensure consistent circuit performance across the full automotive temperature range for all three substitute options.
