Substitute Part Grouping Explanation

Substitution of the ESR10EZPJ1R3 is permissible when the following conditions are met:

The substitute part must maintain identical resistance value of 1.3 Ohms. The substitute part must be compatible with the 0805 (2012 Metric) package footprint. The substitute part must support the same power rating of 0.4W, 2/5W. The substitute part must retain automotive AEC-Q200 qualification. The substitute part must maintain the same operating temperature range of -55°C ~ 155°C. The substitute part must be thick film composition. The substitute part must comply with ROHS3 and maintain MSL 1 rating.

Tolerance may be improved from ±5% to ±1% without affecting circuit compatibility, provided the design does not depend on the original tolerance specification. Temperature coefficient may be improved from ±200ppm/°C to ±100ppm/°C without affecting circuit performance.

Engineering Selection Recommendations

The ESR10EZPF1R30 serves as a direct substitute for the ESR10EZPJ1R3 with enhanced specifications. Both parts maintain active production status and full AEC-Q200 automotive qualification. The substitute part offers improved tolerance of ±1% compared to the original ±5%, along with a superior temperature coefficient of ±100ppm/°C versus ±200ppm/°C. These improvements do not introduce compatibility issues and are fully backward compatible with designs specified for the ESR10EZPJ1R3. Both parts comply with ROHS3 requirements and maintain identical MSL 1 rating. Selection between these parts should be based on tolerance requirements of the specific application and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ESR10EZPF1R30 be used as a direct replacement for ESR10EZPJ1R3?

A: Yes. Both parts share identical resistance value, power rating, package footprint, operating temperature range, and automotive qualification. The substitute part features improved tolerance and temperature coefficient specifications.

Q: Are there any footprint or mounting differences between these parts?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.026" (0.65mm). PCB layout and assembly processes remain unchanged.

Q: What is the significance of the tolerance difference?

A: The ESR10EZPJ1R3 carries ±5% tolerance while ESR10EZPF1R30 carries ±1% tolerance. The tighter tolerance of the substitute part provides greater resistance value accuracy. Applications requiring strict resistance specifications benefit from the improved tolerance.

Q: Do both parts meet automotive standards?

A: Yes. Both parts carry AEC-Q200 qualification and are suitable for automotive applications. Both comply with ROHS3 requirements and maintain MSL 1 rating.

Q: Is the temperature coefficient difference significant?

A: The ESR10EZPJ1R3 has a temperature coefficient of ±200ppm/°C while ESR10EZPF1R30 has ±100ppm/°C. The substitute part exhibits lower resistance drift across the operating temperature range of -55°C ~ 155°C, providing improved stability in temperature-sensitive applications.
