Substitute Part Grouping Explanation

Substitute parts for the TRR01MZPJ4R7 are qualified based on the following electrical and mechanical parameters:

Resistance value: 4.7 Ohms (exact match required)
Tolerance: ±5% (exact match required)
Power rating: 0.063W / 1/16W (exact match required)
Package: 0402 (1005 Metric) (exact match required)
Composition: Thick Film (exact match required)
Features: Anti-Sulfur coating (required)
Operating temperature range: -55°C ~ 155°C (minimum requirement)
RoHS3 compliance (required for regulatory alignment)
Moisture Sensitivity Level 1 (required)

Substitutes must maintain identical electrical performance and physical footprint compatibility. Temperature coefficient and height variations within specified tolerances are acceptable provided all other parameters remain equivalent.

Engineering Selection Recommendations

SFR01MZPJ4R7 (Rohm Semiconductor) is the primary substitute for TRR01MZPJ4R7. Both parts are manufactured by Rohm Semiconductor and share identical electrical specifications and physical dimensions. The SFR01MZPJ4R7 maintains active product status, ensuring long-term availability and supply chain stability. This part is the direct functional equivalent with no performance trade-offs.

AF0402JR-074R7L (YAGEO) is a secondary substitute suitable for applications requiring automotive-grade qualification. This part meets AEC-Q200 automotive standards and maintains all core electrical parameters. The temperature coefficient specification (±200 ppm/°C) is tighter than the original part, providing improved stability. Physical height is marginally reduced (0.37mm vs 0.40mm), which remains within standard PCB assembly tolerances for 0402 packages. This part is appropriate for automotive and high-reliability applications.

Both substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature ranges. Selection between substitutes depends on application requirements: standard industrial applications favor SFR01MZPJ4R7, while automotive or high-reliability designs benefit from AF0402JR-074R7L.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ4R7 be used as a direct replacement for TRR01MZPJ4R7?

A: Yes. Both parts share identical resistance (4.7 Ohms), tolerance (±5%), power rating (0.063W), package (0402), composition (thick film), anti-sulfur features, operating temperature range (-55°C ~ 155°C), and RoHS3 compliance. The SFR01MZPJ4R7 is the direct functional equivalent with active product status.

Q: What is the difference between SFR01MZPJ4R7 and AF0402JR-074R7L?

A: Both parts meet the core electrical requirements. AF0402JR-074R7L includes automotive AEC-Q200 qualification and features a tighter temperature coefficient (±200 ppm/°C vs -250/+500 ppm/°C). Physical height is 0.37mm versus 0.40mm, a difference within standard PCB assembly tolerances. AF0402JR-074R7L is preferred for automotive and high-reliability applications.

Q: Are there any PCB layout considerations when substituting these parts?

A: All three parts use the 0402 (1005 Metric) package with identical footprints. Height variation between TRR01MZPJ4R7 / SFR01MZPJ4R7 (0.40mm) and AF0402JR-074R7L (0.37mm) is negligible for standard PCB assembly processes and does not require layout modifications.

Q: Do these substitutes maintain the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute should be selected for new designs?

A: SFR01MZPJ4R7 is recommended for standard applications due to identical specifications and active manufacturer support. AF0402JR-074R7L is recommended for automotive, aerospace, or high-reliability applications requiring AEC-Q200 qualification.
