TRR03EZPJ272 Equivalent & Substitute Parts

Part Overview

The TRR03EZPJ272 is a 2.7 kOhms ±5% 0.1W chip resistor in 0603 (1608 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 product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the TRR03EZPJ272 is determined by strict equivalence in the following parameters:

• Resistance value: 2.7 kOhms (exact match required)
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance
• MSL 1 rating

Tolerance, composition (thick film vs. thin film), and temperature coefficient may vary within acceptable substitution criteria. Automotive AEC-Q200 certification is an enhancement feature available in substitute parts but not required for functional equivalence.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the TRR03EZPJ272 and meet the core substitution criteria. Selection should be based on product availability and application requirements:

AT0603DRE072K7L (YAGEO) provides the tightest tolerance specification at ±0.5% with thin film construction and the lowest temperature coefficient at ±50ppm/°C. This part includes automotive AEC-Q200 certification and moisture resistance features.

ERJ-S03F2701V (Panasonic) offers ±1% tolerance with thick film composition and ±100ppm/°C temperature coefficient. Automotive AEC-Q200 certification is included.

ERJ-S03J272V (Panasonic) matches the original tolerance specification at ±5% with thick film composition and ±200ppm/°C temperature coefficient, maintaining the closest electrical characteristics to the TRR03EZPJ272. Automotive AEC-Q200 certification is included.

All substitute parts are active products with confirmed inventory availability and full ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can AT0603DRE072K7L replace TRR03EZPJ272 directly?

A: Yes. Both parts share identical resistance value, power rating, package, operating temperature range, and compliance certifications. The AT0603DRE072K7L features improved tolerance (±0.5% vs. ±5%) and lower temperature coefficient, making it a direct functional substitute.

Q: What is the difference between thick film and thin film composition in these resistors?

A: Composition differences affect temperature coefficient and tolerance capabilities. Thin film resistors (AT0603DRE072K7L) typically achieve tighter tolerances and lower temperature coefficients. Thick film resistors (ERJ-S03F2701V, ERJ-S03J272V) match the original TRR03EZPJ272 composition. Both compositions are suitable for the 0603 package and specified operating range.

Q: Are all substitute parts automotive-qualified?

A: Yes. All three substitute parts carry AEC-Q200 automotive qualification, which exceeds the original TRR03EZPJ272 specification and provides additional reliability assurance.

Q: Can I use these substitutes in high-temperature applications?

A: All parts operate across -55°C to 155°C. For applications requiring operation at the upper temperature limit, ERJ-S03J272V maintains the original temperature coefficient specification (±200ppm/°C), while AT0603DRE072K7L and ERJ-S03F2701V offer improved stability with lower temperature coefficients.

Q: What is MSL 1 rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture precautions required. All listed parts carry MSL 1 rating, ensuring compatibility with standard storage and handling procedures.
