TRR01MZPJ184 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ184 is a 180 kOhms ±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 part is currently obsolete. Due to its discontinued status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure supply chain reliability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: resistance value (180 kOhms), tolerance (±5%), package format (0402), composition (thick film), anti-sulfur feature, operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). Substitute parts are grouped into two categories:

Direct Equivalents: Parts that match all electrical and mechanical specifications of the original TRR01MZPJ184, including power rating (0.063W), tolerance (±5%), and temperature coefficient (±200ppm/°C). These parts are pin-compatible and functionally identical.

Upgrade Substitutes: Parts that exceed the original specifications in power rating (0.1W vs. 0.063W) or tolerance (±1% vs. ±5%), while maintaining all other critical parameters. These parts provide enhanced performance margins and are backward-compatible with the original design.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): SFR01MZPJ184 from Rohm Semiconductor is the primary direct equivalent. It maintains all electrical and mechanical specifications of the TRR01MZPJ184 while offering active product status and AEC-Q200 automotive qualification. AA0402JR-07180KL from YAGEO provides an alternative direct equivalent with active status, AEC-Q200 qualification, and moisture-resistant features, though with a slightly lower temperature coefficient (±150ppm/°C vs. ±200ppm/°C).

For Enhanced Performance (Upgrade Substitutes): ERJ-S02J184X and ERJ-S02F1803X from Panasonic Electronic Components both offer increased power rating (0.1W vs. 0.063W), providing additional thermal margin. ERJ-S02F1803X further improves tolerance to ±1%, suitable for applications requiring tighter resistance control. Both parts carry AEC-Q200 qualification and active product status.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the required anti-sulfur coating. Selection should be based on application requirements for power dissipation margin, tolerance precision, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ184 be used as a direct replacement for TRR01MZPJ184? A: Yes. SFR01MZPJ184 matches all critical electrical and mechanical parameters: 180 kOhms ±5%, 0.063W power rating, 0402 package, ±200ppm/°C temperature coefficient, and anti-sulfur composition. The primary difference is product status (active vs. obsolete) and the addition of AEC-Q200 automotive qualification.

Q: What is the difference between direct equivalents and upgrade substitutes? A: Direct equivalents (SFR01MZPJ184, AA0402JR-07180KL) maintain identical power ratings and tolerances. Upgrade substitutes (ERJ-S02J184X, ERJ-S02F1803X) provide higher power ratings (0.1W) and/or tighter tolerances (±1%), offering enhanced performance margins while remaining functionally compatible.

Q: Are all substitute parts qualified for automotive applications? A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification. The original TRR01MZPJ184 does not specify AEC-Q200 qualification.

Q: Does the 0402 package remain the same across all substitutes? A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W). Physical board layout compatibility is maintained.

Q: Can ERJ-S02F1803X (±1% tolerance) be used in place of TRR01MZPJ184 (±5% tolerance)? A: Yes. The ±1% tolerance is tighter than the original ±5% specification, making it a valid upgrade substitute. Applications requiring the original ±5% tolerance will function correctly with ±1% parts.

Q: What is the impact of the temperature coefficient difference in AA0402JR-07180KL? A: AA0402JR-07180KL has a temperature coefficient of ±150ppm/°C compared to the original ±200ppm/°C. This represents improved temperature stability and is suitable for all applications designed for the original part.
