ESR18EZPJ200 Equivalent & Substitute Parts

Part Overview

The ESR18EZPJ200 is a 20 Ohms ±5% 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, package dimensions, and automotive qualification requirements.

Substitute Part Grouping Explanation

Substitution of the ESR18EZPJ200 is determined by the following critical parameters: resistance value (20 Ohms), package type (1206), automotive qualification (AEC-Q200), and operating temperature range (-55°C ~ 155°C). Tolerance and power rating variations are permitted within the constraints of circuit design requirements. The substitute parts are grouped into two categories:

Upgrade Category: Parts with improved tolerance (±1%) or increased power rating (0.667W or 0.75W) that maintain or exceed the original specifications.

Direct Equivalent Category: Parts with matching tolerance (±5%) and power rating (0.5W) that provide functional equivalence with potential minor dimensional variations.

All substitute parts maintain the same 1206 package footprint, AEC-Q200 automotive rating, ROHS3 compliance, and operating temperature range as the main part.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full AEC-Q200 automotive qualification with ROHS3 compliance. Selection between the main part and substitutes depends on circuit-specific requirements:

The ESR18EZPF20R0 (Rohm Semiconductor) provides improved tolerance specification (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C) while maintaining identical power rating and package dimensions.

The ERJ-P08J200V (Panasonic Electronic Components) offers increased power dissipation capability (0.667W versus 0.5W) with matching tolerance and temperature coefficient, suitable for applications requiring higher thermal margin.

The SR1206JR-7W20RL (YAGEO) provides direct functional equivalence with matching tolerance and power rating, with minor length dimension variation (3.10mm versus 3.20mm) that remains within 1206 package specification.

The CRCW120620R0JNEAHP (Vishay Dale) delivers the highest power rating (0.75W) among substitutes while maintaining tolerance and temperature coefficient specifications, with length dimension matching the YAGEO part.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF20R0 be used as a direct replacement for ESR18EZPJ200?

A: Yes. Both parts share identical resistance (20 Ohms), power rating (0.5W), package (1206), and operating temperature range (-55°C ~ 155°C). The ESR18EZPF20R0 provides improved tolerance (±1% versus ±5%) and lower temperature coefficient, making it a superior upgrade option.

Q: What is the difference between the 0.5W and 0.667W power ratings?

A: Power rating indicates maximum continuous power dissipation capability. The ERJ-P08J200V at 0.667W provides approximately 33% greater thermal headroom than the 0.5W rated parts. Selection depends on circuit current and thermal design requirements.

Q: Are there dimensional compatibility concerns with the substitute parts?

A: All substitute parts conform to the 1206 (3216 Metric) package standard. Minor length variations exist (3.10mm versus 3.20mm), but both dimensions fall within 1206 package specification and are compatible with standard PCB footprints. Height variations (0.65mm to 0.70mm) are negligible for typical assembly processes.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and ROHS3 compliance, matching the original ESR18EZPJ200 specifications.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient (±100ppm/°C versus ±200ppm/°C) indicates resistance value drift over temperature. Lower values provide better stability. The ESR18EZPF20R0 and SR1206JR-7W20RL offer superior temperature stability compared to the main part and other substitutes.
