Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1241-P-T1 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 1.24 kOhms
• Tolerance: ±0.02%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RG2012V-1241-P-T1 qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product status (active versus obsolete) and packaging format (Tape & Reel versus standard packaging), with the substitute offering improved temperature coefficient performance (±5ppm/°C versus ±25ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

The RG2012V-1241-P-T1 is the direct active equivalent for the obsolete RG2012P-1241-P-T1. Both components are manufactured by Susumu and maintain identical electrical and mechanical specifications, including resistance value, tolerance, power rating, package dimensions, and automotive AEC-Q200 qualification.

The substitute part offers superior temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), which provides enhanced stability across the full operating temperature range of -55°C to 155°C. This improvement does not introduce any compatibility concerns and represents a performance enhancement for precision applications.

Both parts comply with ROHS3 requirements and carry MSL 1 moisture sensitivity rating, ensuring equivalent handling and storage protocols. The primary operational difference is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for active production components and offers advantages for automated assembly processes.

Selection of the RG2012V-1241-P-T1 is appropriate for all applications previously specified for the RG2012P-1241-P-T1, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-1241-P-T1 be used as a direct replacement for the RG2012P-1241-P-T1?

A: Yes. Both components share identical resistance value (1.24 kOhms), tolerance (±0.02%), power rating (0.125W), package (0805), composition (thin film), and automotive AEC-Q200 qualification. Mechanical dimensions and environmental operating ranges are equivalent. The substitute is electrically and mechanically interchangeable.

Q: What is the difference between the two parts?

A: The RG2012V-1241-P-T1 is the active production equivalent of the obsolete RG2012P-1241-P-T1. The substitute offers improved temperature coefficient (±5ppm/°C versus ±25ppm/°C) and is supplied in Tape & Reel packaging. All other specifications remain identical.

Q: Does the improved temperature coefficient of the substitute part affect circuit design?

A: No. The tighter temperature coefficient of the RG2012V-1241-P-T1 represents a performance improvement that maintains backward compatibility. Circuits designed for the original part will function identically with the substitute, with enhanced temperature stability as an additional benefit.

Q: Are there any packaging considerations when switching to the substitute?

A: The RG2012V-1241-P-T1 is supplied in Tape & Reel (TR) format, which is standard for active production components. This packaging is compatible with automated pick-and-place assembly equipment. If manual assembly or alternative packaging is required, this should be confirmed with the supplier.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the RG2012P-1241-P-T1 and RG2012V-1241-P-T1 are ROHS3 compliant, carry AEC-Q200 automotive qualification, and have MSL 1 moisture sensitivity rating. Compliance and handling requirements are identical.

Q: Is the substitute part currently available?

A: The RG2012V-1241-P-T1 is classified as active product status with documented inventory availability. The original RG2012P-1241-P-T1 is obsolete, making the substitute the recommended source for ongoing supply.
