RG2012N-112-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012N-112-D-T5 is a 1.1 kOhms ±0.5% 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 features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and available in high volume inventory. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate enhanced tolerance specifications.

Substitute Part Grouping Explanation

Substitution of the RG2012N-112-D-T5 is permissible with parts that maintain identical electrical and mechanical specifications across the following critical parameters:

• Resistance value: 1.1 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitute parts (ERA-6ARB112V and ERA-6ARW112V) satisfy all mandatory compatibility criteria. These Panasonic Electronic Components parts offer enhanced tolerance specifications (±0.1% and ±0.05% respectively) compared to the primary part's ±0.5% tolerance, representing functional upgrades within the same package and electrical class.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full AEC-Q200 automotive qualification and ROHS3 compliance. The RG2012N-112-D-T5 serves as the baseline specification with ±0.5% tolerance. The ERA-6ARB112V provides a tolerance upgrade to ±0.1%, and the ERA-6ARW112V offers the highest precision at ±0.05% tolerance. Selection between these parts depends on circuit tolerance requirements and application specifications. All substitute parts are electrically and mechanically compatible within the 0805 package format, with seated height differences of 0.004" (0.10mm) maximum between the primary part and substitutes. This minor dimensional variance remains within standard PCB assembly tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARB112V and ERA-6ARW112V be used interchangeably with RG2012N-112-D-T5?

A: Yes. Both Panasonic parts are direct substitutes. They maintain identical resistance value, power rating, package format, temperature coefficient, operating temperature range, and automotive qualification. The primary differences are enhanced tolerance specifications (±0.1% and ±0.05% respectively versus ±0.5%).

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

A: Tolerance defines the acceptable deviation from the nominal 1.1 kOhms resistance value. The RG2012N-112-D-T5 allows ±0.5% deviation (±5.5 Ohms), ERA-6ARB112V allows ±0.1% deviation (±1.1 Ohms), and ERA-6ARW112V allows ±0.05% deviation (±0.55 Ohms). Applications requiring tighter resistance control benefit from the lower tolerance substitutes.

Q: Are there package compatibility concerns?

A: All three parts use the 0805 (2012 Metric) package. The seated height difference is 0.004" (0.10mm), with the Susumu part at 0.020" maximum and Panasonic parts at 0.024" maximum. This variance is within standard PCB assembly specifications for 0805 components and does not affect board-level compatibility.

Q: Do all parts meet automotive standards?

A: Yes. All three parts carry AEC-Q200 qualification, confirming suitability for automotive applications. All are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity rating?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts available in the same packaging format?

A: Yes. All three parts are supplied in Tape & Reel (TR) format, enabling compatibility with standard automated assembly processes.
