TRR01MZPJ270 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ270 is a 27 Ohm ±5% 1/16W (0.063W) 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 design support and production continuity. The TRR series has been superseded by active product lines offering improved specifications and automotive qualification.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (27 Ohms), package type (0402), composition (Thick Film), anti-sulfur feature, operating temperature range (-55°C ~ 155°C), and RoHS3 compliance. Tolerance and power rating variations are permitted within the substitute categories defined below.

Direct Equivalents maintain identical tolerance (±5%) and power rating (0.063W) specifications.

Upgrade Substitutes provide enhanced specifications including higher tolerance accuracy (±1%) and increased power rating (0.1W), suitable for applications requiring improved performance margins.

Engineering Selection Recommendations

For Direct Replacement: SFR01MZPJ270 (Rohm Semiconductor) is the primary equivalent, maintaining identical electrical specifications while offering active product status and AEC-Q200 automotive qualification. This part is sourced in higher inventory volumes (10,837 pcs) compared to the obsolete TRR01MZPJ270.

For Cross-Manufacturer Equivalence: AF0402JR-0727RL (YAGEO) provides direct electrical equivalence with improved temperature coefficient performance (±100ppm/°C vs ±200ppm/°C) and active status with AEC-Q200 qualification.

For Enhanced Performance: ERJ-S02F27R0X (Panasonic) offers upgraded tolerance (±1%) and increased power rating (0.1W) while maintaining all other specifications. ERJ-S02J270X (Panasonic) provides increased power rating (0.1W) with original tolerance (±5%), suitable for applications requiring additional thermal margin without tolerance tightening.

All substitute parts maintain 0402 package compatibility, anti-sulfur composition, operating temperature range, RoHS3 compliance, and MSL 1 rating. Selection should be based on design requirements for tolerance accuracy, power dissipation margin, and preferred supplier qualification status.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ270 be used as a direct replacement for TRR01MZPJ270?

A: Yes. SFR01MZPJ270 maintains identical resistance (27 Ohms), tolerance (±5%), power rating (0.063W), package (0402), composition (Thick Film), and operating temperature range (-55°C ~ 155°C). The primary difference is active product status and AEC-Q200 automotive qualification, making it a superior choice for new designs and production continuity.

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

A: Direct equivalents (SFR01MZPJ270, AF0402JR-0727RL) match the original 0.063W power rating and ±5% tolerance. Upgrade substitutes (ERJ-S02F27R0X, ERJ-S02J270X) provide higher power ratings (0.1W) and/or tighter tolerance (±1%), offering improved performance margins for applications requiring enhanced specifications.

Q: Are all substitute parts qualified for automotive applications?

A: SFR01MZPJ270, AF0402JR-0727RL, ERJ-S02F27R0X, and ERJ-S02J270X all carry AEC-Q200 automotive qualification. The original TRR01MZPJ270 does not have this certification.

Q: Does package compatibility require any PCB layout modifications?

A: No. All listed parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm). No PCB layout changes are required for substitution.

Q: What is the inventory status for each substitute?

A: SFR01MZPJ270 has the highest availability (10,837 pcs), followed by AF0402JR-0727RL (1,050 pcs), ERJ-S02F27R0X (967 pcs), and ERJ-S02J270X (758 pcs). The original TRR01MZPJ270 shows 841 pcs in stock but is obsolete.
