• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RG2012V-3161-P-T1 qualifies as a direct substitute because it maintains identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is product status (active versus obsolete) and packaging format, with the substitute available in Tape & Reel configuration for production environments.

Parameter Comparison

Engineering Selection Recommendations

The RG2012V-3161-P-T1 is the direct functional equivalent for the obsolete RG2012N-3161-P-T1. Both components are manufactured by Susumu and maintain identical electrical performance specifications, mechanical compatibility, and automotive qualification standards. The substitute part is currently in active production status, ensuring long-term availability and supply chain reliability.

The RG2012V-3161-P-T1 offers an improved temperature coefficient of ±5ppm/°C compared to the main part's ±10ppm/°C, providing enhanced temperature stability without compromising any other electrical or mechanical parameters. This enhancement is compatible with all applications designed for the original part.

Both components satisfy ROHS3 compliance and REACH regulatory requirements. The substitute is supplied in Tape & Reel packaging, which is standard for production assembly environments. No design modifications, PCB layout changes, or requalification testing are required when transitioning from RG2012N-3161-P-T1 to RG2012V-3161-P-T1.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-3161-P-T1 be used as a direct replacement for RG2012N-3161-P-T1 in existing designs?

A: Yes. The RG2012V-3161-P-T1 is electrically and mechanically identical to the RG2012N-3161-P-T1. Both components have the same resistance value (3.16 kOhms), tolerance (±0.02%), power rating (0.125W), package dimensions (0805), and AEC-Q200 automotive qualification. No design changes are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The RG2012N-3161-P-T1 is obsolete, while the RG2012V-3161-P-T1 is active production. The substitute is supplied in Tape & Reel packaging. Additionally, the RG2012V-3161-P-T1 features a superior temperature coefficient of ±5ppm/°C versus ±10ppm/°C for the original part.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and rated for AEC-Q200 automotive applications. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.

Q: Will the improved temperature coefficient of the substitute part affect circuit performance?

A: The improved temperature coefficient of ±5ppm/°C in the RG2012V-3161-P-T1 provides better temperature stability compared to the original ±10ppm/°C specification. This enhancement is fully compatible with all applications designed for the original part and will not cause any adverse effects.

Q: Is the 0805 package dimension identical between both parts?

A: Yes. Both the RG2012N-3161-P-T1 and RG2012V-3161-P-T1 use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). PCB footprints are fully compatible.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -55°C to 155°C, ensuring consistent performance in automotive and industrial environments.
