Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-1021-C-T5 is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 1.02 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Power rating: 0.125W (1/8W) (thermal design compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Features: Anti-Sulfur, Automotive AEC-Q200 (environmental and reliability standards)
• Temperature Coefficient: ±5ppm/°C (thermal stability)
• Operating Temperature Range: -55°C ~ 155°C (application environment compatibility)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower tolerance value) than the original ±0.25% specification
• Product Status: Active alternatives are preferred over obsolete status
• Packaging format: Tape & Reel (TR) is acceptable for the obsolete bulk format

All substitute parts listed maintain identical electrical performance specifications and physical dimensions while offering improved tolerance grades and active product status.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are direct functional equivalents to the RG2012V-1021-C-T5 and are suitable for replacement in applications requiring 1.02 kOhms ±0.25% thin film resistors in 0805 package format.

Selection Criteria Based on Product Status and Compliance:

The RG2012V-1021-C-T5 is classified as obsolete. All substitute parts listed carry active product status, ensuring continued availability and supply chain support. Each substitute maintains full ROHS3 compliance, AEC-Q200 automotive qualification, and identical thermal and mechanical specifications.

Tolerance Grade Considerations:

Substitute parts offer tolerance grades tighter than the original specification:

• RG2012V-1021-B-T5: ±0.1% tolerance (tighter than ±0.25%)
• RG2012V-1021-W-T5: ±0.05% tolerance (tighter than ±0.25%)
• RG2012V-1021-W-T1: ±0.05% tolerance (tighter than ±0.25%)
• RG2012V-1021-P-T1: ±0.02% tolerance (tighter than ±0.25%)

Tighter tolerance grades are electrically compatible with applications designed for ±0.25% tolerance and provide enhanced precision for circuits requiring improved accuracy.

Packaging Format:

The original part is supplied in bulk format. All substitute parts are supplied in Tape & Reel (TR) packaging, which is the current industry standard for automated assembly processes and provides equivalent component quality and reliability.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1021-B-T5, RG2012V-1021-P-T1, RG2012V-1021-W-T1, and RG2012V-1021-W-T5 be used interchangeably with RG2012V-1021-C-T5?

A: Yes. All substitute parts maintain identical resistance value (1.02 kOhms), power rating (0.125W), package format (0805), composition (thin film), temperature coefficient (±5ppm/°C), and operating temperature range (-55°C to 155°C). The substitute parts offer tighter tolerance specifications, which are compatible with applications designed for the original ±0.25% tolerance.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance grade and packaging reel type. RG2012V-1021-P-T1 offers the tightest tolerance at ±0.02%, followed by RG2012V-1021-W-T1 and RG2012V-1021-W-T5 at ±0.05%, and RG2012V-1021-B-T5 at ±0.1%. All other electrical and mechanical parameters are identical.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, meeting the same reliability and environmental standards as the original part.

Q: What is the difference between Tape & Reel (TR) packaging and bulk packaging?

A: Tape & Reel packaging is the current industry standard for automated surface mount assembly. Components are supplied on continuous carrier tape wound on reels, enabling high-speed automated placement. Bulk packaging is an older format. Tape & Reel packaging provides equivalent component quality and reliability while supporting modern manufacturing processes.

Q: Can I use a substitute part with tighter tolerance in place of the original?

A: Yes. A component with tighter tolerance (lower tolerance value) is electrically compatible with applications designed for looser tolerance specifications. For example, a ±0.02% part can replace a ±0.25% specification without circuit performance degradation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant and meet current environmental and regulatory requirements.

Q: What is the MSL rating for these parts?

A: All parts, including the original and all substitutes, carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity limitations for storage and handling.
