Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ514 is determined by the following critical parameters: resistance value (510 kOhms), package type (0603), composition (thick film), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Tolerance and power rating variations are permitted within the constraints of the application circuit requirements. Temperature coefficient differences are acceptable provided the operating temperature envelope remains -55°C ~ 155°C or broader.

Two substitute parts meet these criteria:

ESR03EZPF5103 (Rohm Semiconductor): Identical resistance, package, composition, and temperature range. Tolerance upgraded to ±1% with temperature coefficient of ±100ppm/°C. Power rating remains 0.25W. Direct upgrade path for applications requiring tighter tolerance control.

ERJ-PA3J514V (Panasonic Electronic Components): Identical resistance, package, composition, and temperature range. Tolerance matches at ±5% with temperature coefficient of ±200ppm/°C. Power rating increased to 0.333W (1/3W). Functional equivalent with enhanced power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

ESR03EZPF5103 is selected when circuit design requires tolerance tightening from ±5% to ±1% without modifying power dissipation requirements. Both parts are manufactured by Rohm Semiconductor with identical AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. The reduced temperature coefficient (±100ppm/°C versus ±200ppm/°C) provides improved stability across the full operating temperature range.

ERJ-PA3J514V is selected when power dissipation margin must be increased from 0.25W to 0.333W while maintaining ±5% tolerance and ±200ppm/°C temperature coefficient. Panasonic Electronic Components manufacturing ensures equivalent AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Footprint and thermal characteristics remain compatible with 0603 package specifications.

Both substitute parts maintain full compatibility with the original ESR03EZPJ514 in terms of package dimensions, termination count, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF5103 be used as a direct replacement for ESR03EZPJ514?

A: Yes. Both parts share identical resistance (510 kOhms), package (0603), composition (thick film), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The ESR03EZPF5103 provides tighter tolerance (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C) with no footprint or thermal changes.

Q: Can ERJ-PA3J514V be used as a direct replacement for ESR03EZPJ514?

A: Yes. Both parts share identical resistance (510 kOhms), tolerance (±5%), package (0603), composition (thick film), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The ERJ-PA3J514V provides increased power rating (0.333W versus 0.25W) with no footprint changes.

Q: What are the key differences between the two substitute parts?

A: ESR03EZPF5103 offers improved tolerance and temperature stability (±1%, ±100ppm/°C) while maintaining 0.25W power rating. ERJ-PA3J514V maintains ±5% tolerance and ±200ppm/°C temperature coefficient but increases power rating to 0.333W. Both are manufactured by different suppliers (Rohm and Panasonic respectively) with equivalent automotive qualifications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use 0603 (1608 Metric) package with two terminations and identical physical dimensions (0.063" L x 0.031" W, height 0.022" maximum). No PCB layout modifications are required for substitution.

Q: Do all substitute parts meet automotive requirements?

A: Yes. ESR03EZPJ514, ESR03EZPF5103, and ERJ-PA3J514V all carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (unlimited) moisture sensitivity level rating.
