TRR01MZPJ752 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ752 is a 7.5 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 classified as obsolete. Due to its discontinued status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Resistance Value: Must be 7.5 kOhms
Package Type: Must be 0402 (1005 Metric)
Composition: Must be Thick Film
Anti-Sulfur Feature: Required for environmental compatibility
Operating Temperature Range: Must support -55°C ~ 155°C minimum
RoHS Compliance: ROHS3 Compliant required

Substitute parts are grouped into two categories:

Direct Equivalents maintain all electrical and mechanical specifications identical to the original part, differing only in manufacturer or product status (active vs. obsolete).

Upgrade Substitutes provide enhanced specifications (improved tolerance or higher power rating) while maintaining compatibility with the original design requirements. These parts can be used as drop-in replacements with performance benefits.

Engineering Selection Recommendations

SFR01MZPJ752 (Rohm Semiconductor) is the primary direct equivalent. It maintains identical electrical specifications and package format while offering active product status and AEC-Q200 automotive qualification. This part is recommended as the first choice for direct replacement.

AF0402JR-077K5L (YAGEO) provides direct equivalence with improved temperature coefficient performance (±100ppm/°C vs. ±200ppm/°C). Active status and AEC-Q200 qualification make this suitable for applications requiring tighter temperature stability.

ERJ-S02F7501X (Panasonic Electronic Components) is an upgrade substitute offering ±1% tolerance and 0.1W power rating. This part is suitable for designs where improved tolerance and power margin are beneficial, with full AEC-Q200 compliance.

ERJ-S02J752X (Panasonic Electronic Components) is an upgrade substitute maintaining ±5% tolerance while providing 0.1W power rating. This part offers increased power headroom with active status and AEC-Q200 qualification.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ752 be used as a direct replacement for TRR01MZPJ752?

A: Yes. SFR01MZPJ752 maintains identical resistance, tolerance, power rating, package, and operating temperature range. The primary difference is active product status and AEC-Q200 automotive qualification, making it a suitable direct replacement.

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

A: Direct equivalents (SFR01MZPJ752, AF0402JR-077K5L) match all original specifications. Upgrade substitutes (ERJ-S02F7501X, ERJ-S02J752X) provide enhanced tolerance or power rating while maintaining package and resistance compatibility.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, providing enhanced reliability assurance compared to the original obsolete part.

Q: Can ERJ-S02F7501X (±1% tolerance) be used in place of TRR01MZPJ752 (±5% tolerance)?

A: Yes. The ±1% tolerance is tighter than the original ±5% specification, making it compatible with any design accepting the original part. The improved tolerance provides additional design margin.

Q: What is the impact of using ERJ-S02J752X with 0.1W rating instead of 0.063W?

A: The higher power rating (0.1W vs. 0.063W) provides additional thermal margin and is fully compatible. No design modifications are required; the part operates within the same package footprint and temperature range.

Q: Are all parts in the same 0402 package footprint?

A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical land pattern dimensions (0.039" L x 0.020" W), ensuring direct PCB compatibility without layout changes.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited) rating, identical to the original part, requiring no special moisture control during storage or handling.
