ESR01MZPJ182 Equivalent & Substitute Parts

Part Overview

The ESR01MZPJ182 is a 1.8 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0402 (1005 Metric) package format. This component is rated for 0.2W (1/5W) power dissipation and meets automotive AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 8081 pieces available in inventory. Substitute parts are identified when equivalent electrical characteristics, mechanical dimensions, and automotive compliance ratings are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESR01MZPJ182 are qualified based on the following criteria:

Electrical Parameters: Resistance value of 1.8 kOhms, tolerance of ±5%, and temperature coefficient of ±200ppm/°C must be maintained.

Power Rating: Parts must support minimum 0.2W (1/5W) power dissipation. Parts with higher power ratings (0.25W / 1/4W) are acceptable as they provide equivalent or superior thermal performance.

Package Compatibility: 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and height (0.016" / 0.40mm maximum seated height).

Automotive Compliance: AEC-Q200 qualification is required for all substitutes.

Environmental Standards: ROHS3 compliance and MSL 1 rating must be maintained.

Composition: Thick film construction is required.

Three substitute parts meet all specified criteria across manufacturers Vishay Dale and Panasonic Electronic Components.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed maintain identical electrical specifications, package dimensions, and automotive compliance ratings. Selection between ESR01MZPJ182 and its substitutes should be based on:

Inventory Availability: RCS04021K80JNED (Vishay Dale, RCS e3 series) offers the highest inventory level at 5792 pieces. CRCW04021K80JNEDHP (Vishay Dale, CRCW-HP series) provides 5725 pieces. Both represent viable alternatives to the primary part's 8081-piece stock.

Power Rating Consideration: ERJ-PA2J182X (Panasonic, ERJ-PA2 series) features a 0.25W (1/4W) power rating, exceeding the 0.2W specification of the primary part. This higher rating provides additional thermal margin in applications where power dissipation approaches component limits.

Series Continuity: All parts maintain active production status and ROHS3 compliance with MSL 1 rating, ensuring long-term availability and environmental standard adherence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA2J182X be used as a direct substitute despite its higher 0.25W power rating?

A: Yes. The 0.25W (1/4W) rating of ERJ-PA2J182X exceeds the 0.2W requirement of ESR01MZPJ182. Higher power ratings provide equivalent or superior thermal performance in the same physical package and do not create compatibility issues in circuits designed for the lower rating.

Q: Are all substitute parts identical in physical dimensions?

A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable on PCBs designed for 0402 components.

Q: Do all substitutes maintain automotive qualification?

A: Yes. All listed substitute parts carry AEC-Q200 qualification and pulse withstanding capability, meeting the same automotive reliability standards as the primary ESR01MZPJ182 part.

Q: What is the significance of the different series designations (ESR, CRCW-HP, ERJ-PA2, RCS e3)?

A: Series designations identify manufacturer product lines and internal construction variations. Despite different series names, all parts meet identical electrical specifications, tolerance, temperature coefficient, and package requirements, making them functionally equivalent for circuit applications.

Q: Are there differences in temperature coefficient performance between substitutes?

A: No. All parts, including the primary ESR01MZPJ182, maintain a temperature coefficient of ±200ppm/°C and operate across the identical -55°C ~ 155°C temperature range.

Q: Which substitute offers the best inventory position?

A: RCS04021K80JNED provides 5792 pieces in stock, representing the highest available inventory among substitute options. CRCW04021K80JNEDHP follows with 5725 pieces.
