Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESR18EZPJ1R8 is permissible when the following conditions are met:

The substitute part must maintain identical resistance value (1.8 Ohms) and package configuration (1206/3216 Metric). The substitute must support the same power rating (0.5W) and operating temperature range (-55°C to 155°C). The substitute must retain AEC-Q200 automotive qualification and ROHS3 compliance. Tolerance may be improved (tightened) from ±5% to ±1% without affecting circuit compatibility, as this represents enhanced accuracy. Temperature coefficient may be improved from ±200ppm/°C to ±100ppm/°C without affecting circuit compatibility.

The identified substitute ESR18EZPF1R80 meets all these criteria through improved tolerance and temperature coefficient specifications while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPJ1R8 and ESR18EZPF1R80 are active production components from Rohm Semiconductor with full AEC-Q200 automotive qualification and ROHS3 compliance. The ESR18EZPJ1R8 is suitable for applications where ±5% tolerance meets circuit requirements. The ESR18EZPF1R80 provides improved tolerance specification (±1%) and superior temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it appropriate for precision-critical applications or designs requiring tighter resistance stability across temperature variations. Both components share identical package geometry, power rating, and operating temperature range, ensuring direct mechanical and thermal compatibility in 1206 footprint designs.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF1R80 directly replace ESR18EZPJ1R8 in existing designs?

A: Yes. The substitute maintains identical resistance value, package configuration, power rating, and operating temperature range. The improved tolerance and temperature coefficient of the substitute do not create compatibility issues in circuits designed for the original part.

Q: What is the primary difference between these two parts?

A: The ESR18EZPF1R80 features ±1% tolerance compared to ±5% tolerance in the ESR18EZPJ1R8, and a temperature coefficient of ±100ppm/°C versus ±200ppm/°C. These represent performance enhancements rather than functional changes.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 qualification and are rated for automotive use across the -55°C to 155°C operating temperature range.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L × 0.063" W (3.20mm × 1.60mm) and maximum seated height of 0.026" (0.65mm).

Q: What is the moisture sensitivity level for both parts?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
