TRR01MZPJ304 Equivalent & Substitute Parts

Part Overview

The TRR01MZPJ304 is a 300 kOhms ±5% 0.063W, 1/16W Chip Resistor in 0402 (1005 Metric) package manufactured by Rohm Semiconductor. This thick film, anti-sulfur resistor operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently obsolete, making equivalent and substitute components necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (300 kOhms), tolerance (±5%), package format (0402), composition (thick film), and anti-sulfur feature. Parts are grouped into two categories:

Direct Equivalents maintain all electrical and mechanical specifications of the original part. These include SFR01MZPJ304 (Rohm Semiconductor) and AF0402JR-07300KL (YAGEO), both offering identical resistance, tolerance, power rating, and package dimensions.

Upgrade Substitutes provide enhanced specifications while maintaining core compatibility. ERJ-S02F3003X and ERJ-S02J304X (Panasonic Electronic Components) offer improved tolerance (±1% for ERJ-S02F3003X) and higher power rating (0.1W, 1/10W) compared to the original 0.063W specification, with identical resistance and package format.

Engineering Selection Recommendations

For direct replacement of the obsolete TRR01MZPJ304, SFR01MZPJ304 (Rohm Semiconductor) is the primary equivalent, maintaining identical electrical and mechanical specifications while offering active product status and AEC-Q200 automotive qualification. AF0402JR-07300KL (YAGEO) provides an alternative direct equivalent with active status, AEC-Q200 compliance, and a lower temperature coefficient (±100ppm/°C).

For applications requiring enhanced performance margins, ERJ-S02F3003X and ERJ-S02J304X (Panasonic Electronic Components) offer higher power ratings (0.1W versus 0.063W) within the same 0402 package footprint. ERJ-S02F3003X additionally provides tighter tolerance (±1% versus ±5%), suitable for precision circuit requirements. All substitute options maintain ROHS3 compliance, MSL 1 rating, and anti-sulfur thick film construction.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ304 be used as a direct replacement for TRR01MZPJ304?

A: Yes. SFR01MZPJ304 maintains identical resistance (300 kOhms), tolerance (±5%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). Both are anti-sulfur thick film resistors with ROHS3 compliance and MSL 1 rating. SFR01MZPJ304 is currently active and includes AEC-Q200 automotive qualification.

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

A: Direct equivalents (SFR01MZPJ304, AF0402JR-07300KL) replicate all specifications of the original part. Upgrade substitutes (ERJ-S02F3003X, ERJ-S02J304X) provide enhanced specifications—higher power rating (0.1W) and, for ERJ-S02F3003X, tighter tolerance (±1%)—while maintaining the same resistance value and 0402 package.

Q: Are all substitute parts compatible with the original 0402 footprint?

A: Yes. All listed substitutes use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W). Physical board layout compatibility is maintained across all options.

Q: Which substitute offers the best performance upgrade?

A: ERJ-S02F3003X provides the most significant upgrade with ±1% tolerance (versus ±5%) and 0.1W power rating (versus 0.063W), while maintaining the same 300 kOhms resistance and 0402 package. This part is suitable for precision applications requiring tighter resistance tolerance.

Q: Do all substitutes meet automotive standards?

A: SFR01MZPJ304, AF0402JR-07300KL, ERJ-S02F3003X, and ERJ-S02J304X all carry AEC-Q200 automotive qualification. The original TRR01MZPJ304 does not list AEC-Q200 compliance.

Q: What is the temperature coefficient difference between substitutes?

A: TRR01MZPJ304, SFR01MZPJ304, ERJ-S02F3003X, and ERJ-S02J304X specify ±200ppm/°C. AF0402JR-07300KL offers a lower temperature coefficient of ±100ppm/°C, providing better stability across the -55°C to 155°C operating range.
