Key Parameters

Substitute Part Grouping Explanation

Substitution for the TRR10EZPJ2R2 is determined by strict equivalence in the following parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2

Substitute parts are grouped into two categories:

Direct Equivalent (RCS2012J2R2CS): Matches all critical electrical and mechanical parameters with identical power rating (0.125W) and active product status.

Similar Substitutes (CRCW08052R20JQTB, CRGS0805J2R2): Meet core substitution criteria but differ in specific attributes such as power rating, automotive qualification, or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RCS2012J2R2CS (Samsung Electro-Mechanics): This is the primary direct equivalent. It maintains identical electrical specifications (2.2 Ohms ±5%, 0.125W) and mechanical compatibility with the TRR10EZPJ2R2. The part is active in production, ROHS3 compliant, and offers superior temperature coefficient performance (±300ppm/°C versus ±400ppm/°C). Packaging is tape and reel format with 1058 units in stock.

CRCW08052R20JQTB (Vishay Dale): This substitute meets core electrical and mechanical requirements with identical resistance, tolerance, and power rating. It includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade components. However, it is RoHS non-compliant and REACH affected, which may restrict use in certain regulatory environments. Height is reduced to 0.020" (0.50mm), which may affect PCB layout compatibility.

CRGS0805J2R2 (TE Connectivity): This substitute provides higher power dissipation capability (0.5W versus 0.125W) in the same 0805 package footprint, offering design margin for thermal performance. It is RoHS compliant with pulse withstanding features. The higher power rating makes it suitable for applications requiring enhanced thermal headroom, though it may not be necessary for direct replacement in standard applications.

Frequently Asked Questions (FAQ)

Q: Can RCS2012J2R2CS directly replace TRR10EZPJ2R2 without circuit modification?

A: Yes. RCS2012J2R2CS is a direct equivalent with matching resistance (2.2 Ohms), tolerance (±5%), power rating (0.125W), and package (0805). Both operate across -55°C to 155°C with identical mechanical dimensions and termination count.

Q: What is the difference between the substitute parts listed?

A: RCS2012J2R2CS matches all specifications of the original part. CRCW08052R20JQTB adds automotive AEC-Q200 qualification but is RoHS non-compliant. CRGS0805J2R2 provides higher power rating (0.5W) in the same package, offering thermal margin but exceeding the original specification.

Q: Are there height differences that affect PCB assembly?

A: Yes. CRCW08052R20JQTB has a maximum seated height of 0.020" (0.50mm), compared to 0.026" (0.65mm) for the original and other substitutes. This 0.006" difference may impact PCB layout, solder reflow profiles, or component placement in space-constrained designs.

Q: Which substitute is recommended for RoHS-compliant applications?

A: Both RCS2012J2R2CS and CRGS0805J2R2 are RoHS compliant. CRCW08052R20JQTB is RoHS non-compliant and should not be used in applications requiring RoHS certification.

Q: Does temperature coefficient affect substitution suitability?

A: Temperature coefficient differences are minor. RCS2012J2R2CS offers ±300ppm/°C versus ±400ppm/°C for the original and other substitutes. This 100ppm/°C improvement provides better stability across the -55°C to 155°C operating range but does not prevent substitution in standard applications.

Q: Can CRGS0805J2R2 be used as a direct replacement despite higher power rating?

A: Yes. Higher power rating does not prevent substitution. CRGS0805J2R2 maintains identical resistance, tolerance, package, and operating temperature range. The 0.5W rating provides additional thermal margin without affecting electrical performance in circuits designed for 0.125W operation.
