TRR18EZPJ2R2 Equivalent & Substitute Parts

Part Overview

The TRR18EZPJ2R2 is a 2.2 Ohm ±5% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Rohm Semiconductor. This thick film resistor features anti-sulfur construction and operates across -55°C to 155°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specific resistance value and power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TRR18EZPJ2R2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part AA1206JR-072R2L from YAGEO meets all these core electrical and mechanical requirements. Additional features such as automotive AEC-Q200 qualification and moisture resistance in the substitute represent enhanced capabilities that do not compromise compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AA1206JR-072R2L from YAGEO is a direct functional equivalent to the obsolete TRR18EZPJ2R2. Both parts satisfy identical electrical specifications: 2.2 Ohm resistance, ±5% tolerance, 0.25W power rating, and 1206 package format. Both maintain ROHS3 compliance and MSL 1 rating.

The YAGEO substitute offers superior product availability due to active manufacturing status, compared to the obsolete Rohm part. The AA1206JR-072R2L includes automotive AEC-Q200 qualification and enhanced moisture resistance, which provide additional reliability margins without altering the core electrical performance required for standard applications.

The temperature coefficient of the YAGEO part (±200ppm/°C) is tighter than the original (±400ppm/°C), representing improved stability across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can AA1206JR-072R2L replace TRR18EZPJ2R2 in existing designs?

A: Yes. Both parts share identical resistance (2.2 Ohms), tolerance (±5%), power rating (0.25W), and 1206 package dimensions. Electrical and mechanical compatibility is complete.

Q: What is the difference in temperature coefficient between these parts?

A: The TRR18EZPJ2R2 has ±400ppm/°C while the AA1206JR-072R2L has ±200ppm/°C. The substitute exhibits tighter temperature stability, which is advantageous for precision applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the TRR18EZPJ2R2 and AA1206JR-072R2L are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why does the substitute have AEC-Q200 qualification?

A: AEC-Q200 is an automotive reliability standard. The YAGEO part meets this specification, providing additional qualification for automotive and high-reliability applications. This does not affect compatibility with non-automotive designs.

Q: Are there packaging differences between these parts?

A: Both parts use 1206 (3216 Metric) package format. The AA1206JR-072R2L is supplied in Tape & Reel (TR) packaging. Physical dimensions and footprint are equivalent for PCB assembly.
