Parameter Comparison

Engineering Selection Recommendations

The RG2012V-1240-P-T1 is a direct functional equivalent to the RG2012P-1240-P-T1. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The substitute part is manufactured by the same supplier (Susumu) within the same RG series.

The RG2012V-1240-P-T1 offers an engineering advantage through improved temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), resulting in superior stability across the operating temperature range. This enhanced performance characteristic does not compromise compatibility and represents a beneficial upgrade path.

The RG2012V-1240-P-T1 maintains active product status with confirmed inventory availability, whereas the RG2012P-1240-P-T1 is obsolete. Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. The substitute part is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-1240-P-T1 be used as a direct replacement for the RG2012P-1240-P-T1?

A: Yes. The RG2012V-1240-P-T1 is a direct functional equivalent. Both components have identical resistance (124 Ohms), tolerance (±0.02%), power rating (0.125W), package type (0805), and all compliance certifications. Physical dimensions and termination count are identical, enabling direct substitution in existing designs and PCB layouts.

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

A: The primary differences are product status and temperature coefficient. The RG2012P-1240-P-T1 is obsolete with a temperature coefficient of ±25ppm/°C. The RG2012V-1240-P-T1 is active with an improved temperature coefficient of ±5ppm/°C, providing superior thermal stability. The substitute part is supplied in Tape & Reel packaging.

Q: Are there any compatibility concerns with PCB assembly?

A: No compatibility concerns exist. Both parts use the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 0.020" maximum height). They are compatible with standard surface mount assembly equipment and processes. The substitute part's Tape & Reel packaging is standard for automated pick-and-place operations.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RG2012P-1240-P-T1 and RG2012V-1240-P-T1 carry AEC-Q200 automotive qualification. Both are ROHS3 compliant and REACH unaffected. Both maintain Moisture Sensitivity Level 1 (unlimited shelf life). Compliance certifications are identical.

Q: What is the temperature coefficient difference, and does it matter for my application?

A: The RG2012V-1240-P-T1 has a temperature coefficient of ±5ppm/°C compared to ±25ppm/°C for the RG2012P-1240-P-T1. This means the substitute part's resistance value changes less with temperature variations. For applications operating across the full -55°C to 155°C range, the substitute provides improved stability and accuracy. Both parts operate across the identical temperature range.

Q: Is the substitute part currently available?

A: Yes. The RG2012V-1240-P-T1 is classified as active product status with 696 pieces in stock. The RG2012P-1240-P-T1 is obsolete but has 1092 pieces in current inventory.

Q: Can I use the RG2012V-1240-P-T1 in new designs?

A: Yes. The RG2012V-1240-P-T1 is the recommended choice for new designs. It is active product status, offers superior temperature coefficient performance, and maintains all required automotive and compliance certifications. It is suitable for both new development and replacement of obsolete inventory.
