Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-621-C-T5 is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Resistance value: 620 Ohms
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height - Seated (Max): 0.020" (0.50mm)
• Compliance: ROHS3, REACH Unaffected, AEC-Q200

Variable Parameter (Allows Substitution):

• Tolerance: The RG2012V-621-C-T5 specifies ±0.25% tolerance. Substitute parts with equal or tighter (lower) tolerance values are electrically compatible and functionally superior for precision applications.

All substitute parts listed maintain identical electrical performance, mechanical compatibility, and automotive qualification while offering improved tolerance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Transition):

The RG2012V-621-C-T5 is obsolete. All four substitute parts are active products manufactured by Susumu and maintain full electrical and mechanical compatibility. Selection among substitutes depends on tolerance requirements:

RG2012V-621-W-T5 or RG2012V-621-W-T1 (±0.05% Tolerance)

• Recommended for applications where the original ±0.25% tolerance is acceptable but improved precision is beneficial
• Both parts offer tighter tolerance than the main part while maintaining identical electrical characteristics
• RG2012V-621-W-T5 and RG2012V-621-W-T1 differ only in tape reel configuration (T5 vs T1)

RG2012V-621-B-T5 (±0.1% Tolerance)

• Suitable for applications requiring intermediate precision between ±0.25% and ±0.05%
• Provides measurable tolerance improvement over the obsolete part

RG2012V-621-P-T1 (±0.02% Tolerance)

• Specified for high-precision applications demanding the tightest tolerance available
• Highest inventory availability (1125 Pcs)
• Recommended for new designs where precision is a critical design parameter

All substitute parts carry identical AEC-Q200 automotive qualification, anti-sulfur coating, ROHS3 compliance, and operating temperature range. Physical footprint and mounting characteristics are identical across all parts, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-621-C-T5 be replaced with any of the listed substitute parts?

A: Yes. All substitute parts are direct replacements. They maintain identical resistance value (620 Ohms), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating range (-55°C to 155°C), and automotive qualification (AEC-Q200). The substitutes offer equal or superior tolerance specifications.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification and product status. RG2012V-621-B-T5 offers ±0.1% tolerance, RG2012V-621-W-T5 and RG2012V-621-W-T1 offer ±0.05% tolerance, and RG2012V-621-P-T1 offers ±0.02% tolerance. All are active products with full inventory availability.

Q: Are there physical or dimensional differences between the main part and substitutes?

A: No. All parts share identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm). PCB footprint and mounting requirements are identical.

Q: Does tighter tolerance affect circuit performance?

A: Tighter tolerance specifications provide improved precision and reduced resistance variation across temperature and time. Circuits designed for ±0.25% tolerance operate correctly with parts specified at ±0.1%, ±0.05%, or ±0.02% tolerance. No circuit redesign is required.

Q: What is the difference between T5 and T1 tape reel configurations?

A: T5 and T1 designations refer to different tape reel specifications for automated assembly. Both configurations contain identical electrical components. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, anti-sulfur coating, and are rated for -55°C to 155°C operating temperature range, identical to the main part.

Q: Is the RG2012V-621-C-T5 still available?

A: The RG2012V-621-C-T5 is classified as obsolete. However, 754 pieces remain in current inventory. For new production and long-term supply assurance, transition to active substitute parts is recommended.

Q: Which substitute part should be selected for new designs?

A: For new designs, RG2012V-621-P-T1 is recommended due to highest inventory availability (1125 Pcs), active product status, and superior ±0.02% tolerance specification. This part provides maximum precision and supply chain continuity.
