Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-392-P-T1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.9 kOhms
• Tolerance: ±0.02%
• Power rating: 0.125W (1/8W)
• Package type: 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 level: 1 (Unlimited)

The RG2012V-392-P-T1 qualifies as a direct substitute based on complete alignment with all mandatory parameters. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging format (bulk versus tape & reel), neither of which affects electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RG2012V-392-P-T1 is the direct functional equivalent of the RG2012P-392-P-T1. Both components are manufactured by Susumu and share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The substitute part is currently in active production status, ensuring long-term supply availability compared to the obsolete main part number.

The RG2012V-392-P-T1 exhibits superior temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), providing enhanced stability across the full operating temperature range. This characteristic represents an improvement in precision without introducing any compatibility concerns.

Both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for automotive and high-reliability applications. The packaging difference (tape & reel versus bulk) reflects standard industry distribution practices and does not affect component performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-392-P-T1 be used as a direct replacement for the RG2012P-392-P-T1 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including resistance, tolerance, power rating, package dimensions, and operating temperature range. The substitute part is fully compatible with existing PCB layouts and assembly processes.

Q: What is the significance of the different temperature coefficients?

A: The RG2012V-392-P-T1 exhibits a temperature coefficient of ±5ppm/°C compared to ±25ppm/°C for the RG2012P-392-P-T1. This represents superior temperature stability in the substitute part, resulting in more consistent resistance values across the -55°C to 155°C operating range. This improvement does not create compatibility issues and may enhance circuit performance.

Q: Does the tape & reel packaging of the substitute part affect component quality or performance?

A: No. Tape & reel packaging is a standard distribution format that does not alter component electrical characteristics, mechanical properties, or reliability. The packaging format reflects manufacturing and logistics practices only.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the RG2012P-392-P-T1 and RG2012V-392-P-T1 carry AEC-Q200 automotive qualification and anti-sulfur coating, confirming suitability for automotive-grade applications requiring high reliability and environmental resistance.

Q: What is the practical implication of the RG2012P-392-P-T1 being obsolete?

A: The obsolete status indicates that the main part number is no longer in active production. The RG2012V-392-P-T1 substitute ensures continued availability of functionally equivalent components for new production runs, design revisions, and field replacements.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1). Regulatory and environmental certifications are equivalent across both part numbers.
