TRR01MZPJ185 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ185 is a 1.8 MOhms ±5% thick film chip resistor in 0402 (1005 Metric) package rated for 0.063W (1/16W) power dissipation. Manufactured by Rohm Semiconductor, this component features anti-sulfur construction and operates across -55°C to 155°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the TRR01MZPJ185 is determined by strict equivalence across the following parameters:

Resistance value: 1.8 MOhms
Tolerance: ±5%
Power rating: 0.063W (1/16W)
Package: 0402 (1005 Metric)
Composition: Thick Film
Operating temperature range: -55°C to 155°C
Moisture Sensitivity Level: 1 (Unlimited)
Number of terminations: 2

All substitute parts listed meet these core electrical and mechanical requirements. Variations in temperature coefficient (±150ppm/°C vs ±200ppm/°C), additional features (Automotive AEC-Q200 certification, moisture resistance), and compliance status (RoHS, REACH) are secondary considerations that do not affect functional substitutability for standard applications.

Engineering Selection Recommendations

For applications requiring RoHS3 compliance, select from: SFR01MZPJ185 (Rohm Semiconductor), AA0402JR-071M8L (YAGEO), CRCW04021M80JNED (Vishay Dale), or RMCF0402JT1M80 (Stackpole Electronics Inc). All four parts are active products with full compliance documentation.

For applications requiring REACH compliance, exclude CRCW04021M80JNTD. This part is REACH Affected and RoHS non-compliant.

SFR01MZPJ185 provides direct manufacturer continuity from Rohm Semiconductor with identical electrical specifications and temperature coefficient to the original TRR01MZPJ185.

AA0402JR-071M8L offers a tighter temperature coefficient (±150ppm/°C) compared to the original specification (±200ppm/°C), providing improved stability in temperature-sensitive applications.

CRCW04021M80JNED and RMCF0402JT1M80 are functionally equivalent alternatives from established manufacturers with active product status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for TRR01MZPJ185?

A: Yes. All listed substitute parts meet the core electrical and mechanical requirements: 1.8 MOhms resistance, ±5% tolerance, 0.063W power rating, 0402 package, thick film composition, and -55°C to 155°C operating range. Physical dimensions and termination count are identical.

Q: What is the difference between the substitute parts?

A: Differences exist in manufacturer, product status (all substitutes are active vs. the original obsolete status), compliance certifications, and temperature coefficient. AA0402JR-071M8L has a ±150ppm/°C temperature coefficient versus ±200ppm/°C for other parts. CRCW04021M80JNTD is RoHS non-compliant and REACH Affected, distinguishing it from other options.

Q: Does the temperature coefficient difference matter?

A: Temperature coefficient affects resistance stability across temperature variations. The ±150ppm/°C specification of AA0402JR-071M8L provides tighter tolerance tracking than ±200ppm/°C. For applications with strict temperature stability requirements, AA0402JR-071M8L is preferable. For standard applications, both specifications are functionally equivalent.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in 0402 (1005 Metric) package with identical physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm). Height variations are minimal (0.015" to 0.016" seated maximum), within standard PCB assembly tolerances.

Q: Which substitute should I choose for automotive applications?

A: SFR01MZPJ185, AA0402JR-071M8L, CRCW04021M80JNED, and RMCF0402JT1M80 all carry Automotive AEC-Q200 certification. CRCW04021M80JNTD also carries AEC-Q200 but lacks RoHS3 compliance. For automotive use with full compliance requirements, select from the first four options.

Q: What is the inventory status of these parts?

A: SFR01MZPJ185 has the highest inventory (11,122 pcs), followed by CRCW04021M80JNED (17,538 pcs). RMCF0402JT1M80 has 7,903 pcs, AA0402JR-071M8L has 794 pcs, and CRCW04021M80JNTD has 756 pcs available.
