Equivalent & Substitute Parts for TRR01MZPJ1R2

Part Overview

The TRR01MZPJ1R2 is a 1.2 Ohm ±5% thick film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W) with anti-sulfur coating. Manufactured by Rohm Semiconductor, this component is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to ensure design continuity and supply chain reliability for new production runs and ongoing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TRR01MZPJ1R2 is determined by strict equivalence across the following parameters:

• Resistance value: 1.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.063W / 1/16W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS3 compliance (required for regulatory alignment)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

The two substitute parts listed below meet all these criteria and are sourced from active manufacturers with current production status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally equivalent to the TRR01MZPJ1R2 and meet all electrical and mechanical requirements for direct replacement.

AA0402JR-071R2L (YAGEO): This part is manufactured by YAGEO and carries AEC-Q200 automotive qualification. It features moisture-resistant thick film construction and maintains the required operating temperature range. The temperature coefficient of ±200 ppm/°C is tighter than the original part's -250/+500 ppm/°C specification, providing improved thermal stability. This part is available in Tape & Reel packaging and is actively produced.

CR0402-J/-1R2GLF (Bourns Inc.): This part is manufactured by Bourns Inc. and maintains identical electrical specifications to the original TRR01MZPJ1R2, including the temperature coefficient of -250/+500 ppm/°C. Physical dimensions and height specifications are equivalent. This part is available in Tape & Reel packaging and is actively produced with high inventory availability.

Both parts satisfy RoHS3 compliance and MSL Level 1 requirements. Selection between these substitutes should be based on supply chain availability, packaging preferences, and any specific automotive qualification requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can AA0402JR-071R2L and CR0402-J/-1R2GLF be used interchangeably with TRR01MZPJ1R2?

A: Yes. Both substitute parts match the critical electrical parameters (1.2 Ohms ±5%, 0.063W power rating) and mechanical specifications (0402 package, identical footprint dimensions). All three parts operate across the same temperature range (-55°C ~ 155°C) and meet RoHS3 compliance with MSL Level 1 rating.

Q: What is the difference in temperature coefficient between the substitute parts?

A: The AA0402JR-071R2L has a temperature coefficient of ±200 ppm/°C, which is tighter than both the original TRR01MZPJ1R2 and CR0402-J/-1R2GLF, which specify -250/+500 ppm/°C. For applications requiring minimal resistance drift over temperature, AA0402JR-071R2L provides superior performance.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in 0402 (1005 Metric) package with identical footprint dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). The AA0402JR-071R2L has a maximum seated height of 0.015" (0.37mm), while both TRR01MZPJ1R2 and CR0402-J/-1R2GLF have 0.016" (0.40mm). This minimal difference does not affect PCB assembly compatibility.

Q: Why is the original TRR01MZPJ1R2 marked as obsolete?

A: Rohm Semiconductor has discontinued the TRR series. The substitute parts from YAGEO and Bourns are actively manufactured and represent the current market standard for this resistance value and package specification.

Q: Do these substitute parts require any design modifications?

A: No. Both substitute parts are pin-compatible and footprint-compatible with the original TRR01MZPJ1R2. No PCB layout or schematic changes are required for direct substitution.
