RG2012V-391-C-T5 Equivalent & Substitute Parts

Part Overview

The RG2012V-391-C-T5 is a 390 Ohms ±0.25% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. This component features anti-sulfur coating and automotive AEC-Q200 qualification, suitable for high-reliability applications requiring precision resistance values across extended temperature ranges from -55°C to 155°C.

The RG2012V-391-C-T5 is classified as obsolete. Equivalent and substitute parts with active product status are available to maintain design continuity and ensure supply chain availability. Substitute components maintain identical resistance values, package dimensions, power ratings, and automotive qualification while offering improved tolerance specifications or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-391-C-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 390 Ohms (exact match required)
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height - Seated (Max): 0.020" (0.50mm)
• RoHS and REACH compliance status

Variable Parameters Allowing Substitution:

• Tolerance specification (tighter tolerances are acceptable upgrades)
• Packaging configuration (Tape & Reel vs. alternative formats)
• Product status (Active substitutes for Obsolete)

All substitute parts listed maintain identical electrical performance characteristics and mechanical compatibility with the original RG2012V-391-C-T5 specification.

Parameter Comparison

Engineering Selection Recommendations

RG2012V-391-B-T5 (±0.1% Tolerance)

This substitute provides improved tolerance specification (±0.1% versus ±0.25%) while maintaining all electrical and mechanical parameters. Product status is Active, ensuring continued availability. This component is suitable for applications requiring tighter resistance tolerance than the original specification.

RG2012V-391-P-T1 (±0.02% Tolerance)

This substitute offers the highest tolerance specification (±0.02%) among available alternatives. Product status is Active. This component is appropriate for precision measurement and calibration circuits where minimal resistance variation is critical.

RG2012V-391-W-T1 (±0.05% Tolerance)

This substitute provides intermediate tolerance specification (±0.05%) with Active product status. Packaging is configured as Tape & Reel (TR). This component balances tolerance performance with standard packaging configurations.

RG2012V-391-W-T5 (±0.05% Tolerance)

This substitute matches the tolerance specification of RG2012V-391-W-T1 (±0.05%) with Active product status. Packaging is configured as Tape & Reel (TR). This component provides equivalent performance characteristics with alternative packaging designation.

All substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur coating, ROHS3 compliance, and REACH unaffected status. Selection among substitutes depends on tolerance requirements and packaging configuration preferences for the specific application.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-391-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical resistance value (390 Ohms), power rating (0.125W), package type (0805), physical dimensions, temperature coefficient, operating temperature range, and automotive AEC-Q200 qualification. Direct replacement is mechanically and electrically compatible.

Q: What is the primary difference between the main part and substitute parts?

A: The RG2012V-391-C-T5 is classified as Obsolete with ±0.25% tolerance. All substitute parts have Active product status with improved or equivalent tolerance specifications (±0.1%, ±0.05%, or ±0.02%).

Q: Does tolerance improvement affect circuit performance?

A: Tighter tolerance specifications reduce resistance variation across the component population. Circuits designed for ±0.25% tolerance will function with tighter tolerance substitutes. Applications requiring specific tolerance bands should select substitutes matching or exceeding the original specification.

Q: Are packaging configurations interchangeable?

A: The RG2012V-391-C-T5 packaging format is not explicitly specified in the main part data. All substitute parts are available in Tape & Reel (TR) packaging. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Do all substitutes maintain automotive qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, anti-sulfur coating, and identical operating temperature range (-55°C to 155°C).

Q: Are there compliance differences between the main part and substitutes?

A: No. All parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Which substitute should be selected for new designs?

A: For new designs, select from Active product status parts based on tolerance requirements. RG2012V-391-W-T5 (±0.05%) provides balanced performance. RG2012V-391-P-T1 (±0.02%) is appropriate for precision applications. RG2012V-391-B-T5 (±0.1%) offers cost-effective performance for standard tolerance requirements.
