RG2012P-123-W-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-123-W-T5 is a 12 kOhms ±0.05% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and is designed for automotive applications with AEC-Q200 qualification. The part features anti-sulfur construction and operates across the temperature range of -55°C to 155°C. The RG2012P-123-W-T5 maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the RG2012P-123-W-T5 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 12 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Thin Film (exact match required)

Mechanical Specifications:

• Package format: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)

Environmental & Compliance:

• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-6ARW123V from Panasonic Electronic Components qualifies as a direct substitute based on matching all critical electrical, mechanical, and compliance parameters. Variations in temperature coefficient (±10ppm/°C versus ±25ppm/°C) and maximum seated height (0.024" versus 0.020") do not disqualify substitution, as these parameters remain within acceptable tolerances for the 0805 package format and do not affect functional equivalence in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012P-123-W-T5 and ERA-6ARW123V maintain Active product status and satisfy identical compliance requirements for automotive applications. Selection between these components should be based on:

Supply Chain Availability: The ERA-6ARW123V currently maintains higher inventory levels (3,940 pieces) compared to the RG2012P-123-W-T5 (974 pieces), supporting procurement timelines and production scheduling.

Automotive Qualification: Both components carry AEC-Q200 certification, confirming suitability for automotive-grade applications with equivalent reliability standards.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component sourcing.

Thermal Performance: The ERA-6ARW123V exhibits superior temperature coefficient performance (±10ppm/°C) compared to the RG2012P-123-W-T5 (±25ppm/°C), providing enhanced stability across the full operating temperature range. This characteristic may be advantageous in precision measurement or high-stability circuit applications.

Physical Clearance: The ERA-6ARW123V maximum seated height of 0.024" (0.60mm) exceeds the RG2012P-123-W-T5 height of 0.020" (0.50mm) by 0.004" (0.10mm). PCB layout verification is required to confirm clearance compatibility in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6ARW123V directly replace the RG2012P-123-W-T5 in existing designs?

A: Yes. Both components share identical electrical specifications (12 kOhms ±0.05%, 0.125W), package format (0805), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Physical dimensions are equivalent (0.079" L x 0.049" W). PCB layout verification is required only to confirm the 0.004" (0.10mm) difference in maximum seated height does not create clearance conflicts.

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

A: The ERA-6ARW123V temperature coefficient of ±10ppm/°C is superior to the RG2012P-123-W-T5 coefficient of ±25ppm/°C. This means the ERA-6ARW123V resistance value remains more stable across temperature variations. For applications requiring high precision or operating across the full -55°C ~ 155°C range, the ERA-6ARW123V provides enhanced performance. For standard applications, both coefficients are acceptable.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG2012P-123-W-T5 and ERA-6ARW123V carry AEC-Q200 automotive qualification, confirming compliance with automotive reliability and quality standards. Both are suitable for automotive-grade circuit designs.

Q: What packaging format is used for these components?

A: Both components are supplied in 0805 (2012 Metric) surface mount package format on Tape & Reel (TR) packaging. This format is standard for automated PCB assembly processes.

Q: Are there any moisture sensitivity concerns with these parts?

A: No. Both components carry Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Q: How do the RoHS and REACH compliance statuses compare?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for component sourcing in regulated markets.
