TRR01MZPJ560 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ560 is a 56 Ohm ±5% 1/16W (0.063W) thick film chip resistor in 0402 (1005 Metric) package manufactured by Rohm Semiconductor. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing production and design requirements. The TRR series has been superseded by active alternatives that maintain electrical compatibility while offering improved availability and automotive qualification.

Substitute Part Grouping Explanation

Substitution for the TRR01MZPJ560 is determined by strict equivalence across the following parameters: resistance value (56 Ohms), tolerance (±5%), package format (0402), composition (thick film), operating temperature range (-55°C to 155°C), and environmental compliance (RoHS3, MSL 1). Substitute parts are grouped into two categories:

Direct Equivalents: Parts maintaining identical electrical specifications and power rating (0.063W, 1/16W) with active product status and improved availability.

Upgrade Alternatives: Parts with enhanced specifications (higher power rating or tighter tolerance) that provide superior performance margins while maintaining full backward compatibility with the original design requirements.

Engineering Selection Recommendations

SFR01MZPJ560 is the primary direct equivalent, manufactured by Rohm Semiconductor with identical electrical specifications to the TRR01MZPJ560. This part maintains the same series lineage, power rating, and tolerance while offering active product status and AEC-Q200 automotive qualification. Selection of this part eliminates obsolescence risk with minimal design impact.

AF0402JR-0756RL (YAGEO) provides direct electrical equivalence with improved temperature coefficient performance (±100ppm/°C versus ±200ppm/°C). This part carries AEC-Q200 qualification and active status, suitable for applications requiring enhanced thermal stability.

ERJ-S02F56R0X and ERJ-S02J560X (Panasonic) represent upgrade alternatives with increased power rating (0.1W versus 0.063W). ERJ-S02F56R0X offers tighter tolerance (±1%), while ERJ-S02J560X maintains ±5% tolerance. Both provide superior thermal headroom and AEC-Q200 qualification for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ560 be used as a direct replacement for TRR01MZPJ560?

A: Yes. SFR01MZPJ560 maintains identical resistance (56 Ohms), tolerance (±5%), power rating (0.063W), package (0402), operating temperature range (-55°C to 155°C), and composition (thick film anti-sulfur). The primary difference is active product status and AEC-Q200 automotive qualification.

Q: What is the difference between direct equivalents and upgrade alternatives?

A: Direct equivalents (SFR01MZPJ560, AF0402JR-0756RL) maintain the original 0.063W power rating and ±5% tolerance. Upgrade alternatives (ERJ-S02F56R0X, ERJ-S02J560X) provide higher power rating (0.1W), offering increased thermal margin. Upgrades are backward compatible but occupy the same 0402 package footprint.

Q: Are all substitute parts RoHS3 compliant?

A: SFR01MZPJ560, AF0402JR-0756RL, ERJ-S02F56R0X, and ERJ-S02J560X are all ROHS3 compliant. The original TRR01MZPJ560 is also ROHS3 compliant.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L × 0.020" W, 1.00mm × 0.50mm). No PCB redesign is required.

Q: Which substitute part offers the best thermal performance?

A: ERJ-S02F56R0X and ERJ-S02J560X provide the highest thermal margin with 0.1W power rating (versus 0.063W original). ERJ-S02F56R0X additionally offers ±1% tolerance for applications requiring tighter resistance control.

Q: Are all substitute parts automotive qualified?

A: SFR01MZPJ560, AF0402JR-0756RL, ERJ-S02F56R0X, and ERJ-S02J560X all carry AEC-Q200 automotive qualification. The original TRR01MZPJ560 does not list AEC-Q200 qualification.
