Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-3012-B-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 30.1 kOhms (exact match required)
• Tolerance: ±0.1% or tighter (±0.05% acceptable as upgrade)
• Package: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (higher ratings acceptable)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C or better (tighter tolerance acceptable)
• Operating temperature range: -55°C ~ 155°C minimum coverage required
• Automotive qualification: AEC-Q200 (required for equivalent substitution)
• RoHS compliance: ROHS3 Compliant (required)

Packaging Consideration: The main part RG2012N-3012-B-T1 is supplied in bulk packaging. Direct equivalents and substitutes are available in Tape & Reel (TR) packaging, which is the standard production format for active components.

Substitution Categories:

1. Direct Equivalents – Identical electrical and mechanical specifications with different packaging or temperature coefficient variants
2. Upgrades – Enhanced tolerance (±0.05% vs ±0.1%) or higher power rating (0.26W vs 0.125W) while maintaining all other critical parameters

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Equivalent Functionality):

RG2012N-3012-B-T5 is the primary direct equivalent. This Susumu component maintains identical electrical specifications (30.1 kΩ ±0.1%, 0.125W, ±10ppm/°C) and mechanical form factor. The part is active and available in standard Tape & Reel packaging. Selection of this part ensures continuity with the original design without performance modification.

For Tolerance-Enhanced Applications:

RG2012N-3012-W-T1 and RG2012N-3012-W-T5 provide tighter tolerance (±0.05% vs ±0.1%) while maintaining all other specifications. These upgrades are suitable for applications requiring improved resistance accuracy. Both parts are active and available from Susumu with identical temperature coefficient and operating range.

For Extended Temperature Range and Higher Power Margin:

TNPW080530K1BYEA and TNPW080530K1BYEN (Vishay Dale) offer 0.26W power rating (vs 0.125W) and extended operating temperature to 175°C (vs 155°C). These parts maintain ±0.1% tolerance and ±10ppm/°C temperature coefficient. Selection is appropriate for applications with thermal margin requirements or higher ambient temperature exposure.

Consideration for RG2012P-3012-B-T5:

This Susumu variant has relaxed temperature coefficient (±25ppm/°C vs ±10ppm/°C). Use only when temperature stability requirements are less stringent than the original specification.

Compliance and Availability:

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. All parts are currently active in production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-3012-B-T5 be used as a direct replacement for RG2012N-3012-B-T1?

A: Yes. RG2012N-3012-B-T5 is electrically and mechanically identical to the obsolete RG2012N-3012-B-T1. The primary difference is packaging format (Tape & Reel vs bulk). Both parts have 30.1 kΩ ±0.1% resistance, 0.125W power rating, ±10ppm/°C temperature coefficient, and -55°C to 155°C operating range. This is the recommended direct equivalent.

Q: What is the difference between RG2012N and RG2012P series?

A: The RG2012N series has ±10ppm/°C temperature coefficient, while RG2012P series has ±25ppm/°C. For applications requiring the original ±10ppm/°C specification, use RG2012N variants. RG2012P is acceptable only when relaxed temperature stability is permitted by design requirements.

Q: Are the Vishay Dale TNPW parts suitable replacements?

A: TNPW080530K1BYEA and TNPW080530K1BYEN are functionally compatible substitutes with enhanced specifications. They provide higher power rating (0.26W vs 0.125W) and extended temperature range (-55°C to 175°C vs -55°C to 155°C). Resistance, tolerance, and temperature coefficient match the original. These parts are suitable when thermal margin or higher temperature operation is required.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and bulk packaging formats contain identical components. Packaging affects only handling, storage, and assembly processes. Electrical and mechanical specifications remain unchanged.

Q: Can I use ±0.05% tolerance parts (RG2012N-3012-W series) as replacements?

A: Yes. Tighter tolerance (±0.05%) is a performance upgrade and is compatible with designs specified for ±0.1%. The part will meet or exceed the original tolerance requirement. Use when improved resistance accuracy benefits the application.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, matching the original component. All parts are ROHS3 compliant and have MSL 1 rating.

Q: What is the maximum operating temperature for each part?

A: RG2012N-3012-B-T1, RG2012N-3012-B-T5, RG2012P-3012-B-T5, RG2012N-3012-W-T1, and RG2012N-3012-W-T5 operate to 155°C. TNPW080530K1BYEA and TNPW080530K1BYEN operate to 175°C. Select based on application thermal requirements.

Q: Is moisture sensitivity a concern for these parts?

A: No. All parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard handling and storage practices apply.
