Part Overview
The ESR01MZPJ181 is a 180 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0402 (1005 Metric) package format. Rated for 0.2W (1/5W) power dissipation with automotive AEC-Q200 qualification and pulse withstanding capability, this component operates across -55°C to 155°C. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and design optimization across multiple manufacturer sources while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitute parts for the ESR01MZPJ181 are qualified based on strict electrical and mechanical parameter matching. All substitute components maintain identical resistance value (180 Ohms), tolerance (±5%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive AEC-Q200 certification, pulse withstanding capability, RoHS3 compliance, and MSL 1 rating.
The primary substitution criterion is equivalence across these parameters. Three substitute parts meet these requirements:
CRCW0402180RJNEDHP (Vishay Dale) and RCS0402180RJNED (Vishay Dale) both maintain 0.2W (1/5W) power rating, matching the main part exactly. ERJ-PA2J181X (Panasonic Electronic Components) provides a higher power rating of 0.25W (1/4W), which is functionally compatible for applications designed around the 0.2W specification due to increased thermal margin.

Engineering Selection Recommendations
All substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements. Selection between the main part and substitutes is based on availability, supply chain considerations, and manufacturer preference within the design organization.
CRCW0402180RJNEDHP and RCS0402180RJNED are direct electrical and mechanical equivalents to ESR01MZPJ181, both from Vishay Dale with identical 0.2W power rating. These parts are interchangeable without circuit redesign or thermal analysis modifications.
ERJ-PA2J181X from Panasonic Electronic Components provides a 0.25W (1/4W) power rating, offering increased thermal headroom compared to the 0.2W specification. This higher power rating is compatible with circuits designed for 0.2W operation and may be selected when thermal margin optimization is beneficial. All other electrical and mechanical parameters remain equivalent.
All four parts carry AEC-Q200 automotive qualification, pulse withstanding capability, and identical temperature coefficient and operating range specifications, supporting direct substitution in automotive and industrial applications.
Frequently Asked Questions (FAQ)
Q: Can ERJ-PA2J181X be used as a direct substitute for ESR01MZPJ181?
A: Yes. ERJ-PA2J181X maintains identical resistance (180 Ohms), tolerance (±5%), package (0402), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), AEC-Q200 rating, and pulse withstanding capability. The higher power rating (0.25W vs 0.2W) provides additional thermal margin and does not restrict substitution in applications designed for 0.2W operation.
Q: Are CRCW0402180RJNEDHP and RCS0402180RJNED interchangeable with ESR01MZPJ181?
A: Yes. Both Vishay Dale parts are complete electrical and mechanical equivalents with matching 0.2W power rating, 180 Ohm resistance, ±5% tolerance, 0402 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 certification, and pulse withstanding features.
Q: What are the key parameters that determine substitution compatibility?
A: Substitution compatibility is determined by resistance value (180 Ohms), tolerance (±5%), power rating (0.2W minimum), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, and pulse withstanding capability. All substitute parts match these parameters.
Q: Do all substitute parts meet automotive and compliance requirements?
A: Yes. All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity level, matching the main part specifications.
Q: Can these parts be used interchangeably on the same PCB assembly?
A: Yes. All parts share identical 0402 (1005 Metric) package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), height (0.016" / 0.40mm maximum), and two-termination configuration, supporting direct PCB footprint compatibility and assembly process interchangeability.
