RG2012N-2102-C-T5 Equivalent & Substitute Parts

Part Overview

The RG2012N-2102-C-T5 is a 21 kOhm ±0.25% 0.125W thin film chip resistor in 0805 package manufactured by Susumu. This component is currently marked as Obsolete in product status. Due to the obsolete status, engineers must identify suitable substitute parts to ensure design continuity, support existing products, and maintain production without disruption.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed maintain identical resistance value (21 kOhms), package size (0805), composition (Thin Film), temperature coefficient (±10ppm/°C), and automotive qualification (AEC-Q200). These parameters ensure mechanical fit and baseline electrical compatibility.

The substitutes are differentiated by tolerance specification:

• RG2012N-2102-B-T5: ±0.1% tolerance
• RG2012N-2102-W-T1: ±0.05% tolerance
• RG2012N-2102-W-T5: ±0.05% tolerance
• TNPW080521K0BYEA: ±0.1% tolerance

All listed substitutes offer tighter tolerance than the original ±0.25% specification. All substitutes meet or exceed the original power rating, with TNPW080521K0BYEA rated at 0.26W.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are marked as Active product status and are ROHS3 Compliant with AEC-Q200 automotive qualification. All parts carry MSL 1 (Unlimited) moisture sensitivity rating and are REACH Unaffected.

RG2012N-2102-B-T5 offers ±0.1% tolerance with identical power rating and operating temperature range within the same Susumu RG series.

RG2012N-2102-W-T1 and RG2012N-2102-W-T5 provide ±0.05% tolerance within the same series, both with Active status and equivalent mechanical dimensions.

TNPW080521K0BYEA from Vishay Dale provides ±0.1% tolerance with 0.26W power rating and extended operating temperature range (-55°C ~ 175°C). This part includes additional Moisture Resistant feature.

All substitutes maintain the same 0805 package dimensions (2.00mm x 1.25mm) and 2-terminal configuration.

Frequently Asked Questions (FAQ)

Q: Can these substitutes directly replace RG2012N-2102-C-T5 without circuit redesign?
A: All listed substitutes maintain identical resistance value, package size, and terminal count. The tighter tolerance specifications are within the original ±0.25% envelope.

Q: How does tolerance difference affect substitution compatibility?
A: All substitutes provide tighter tolerance (±0.1% or ±0.05%) than the original ±0.25%. The tighter tolerance falls within the original specification range.

Q: Are the mechanical dimensions identical across all parts?
A: All parts share 0805 (2012 Metric) package with 0.079" L x 0.049" W (2.00mm x 1.25mm) dimensions. Height varies between 0.020" (0.50mm) and 0.022" (0.55mm) for TNPW080521K0BYEA.

Q: Do all substitutes maintain the same automotive qualification?
A: All parts carry AEC-Q200 automotive qualification and Anti-Sulfur features.

Q: What is the difference between the Susumu RG series substitutes?
A: RG2012N-2102-B-T5 offers ±0.1% tolerance, while RG2012N-2102-W-T1 and RG2012N-2102-W-T5 provide ±0.05% tolerance. Operating temperature range and power rating remain identical across the series.

Q: How does TNPW080521K0BYEA differ from Susumu parts?
A: TNPW080521K0BYEA provides 0.26W power rating, extended operating temperature range (-55°C ~ 175°C), and additional Moisture Resistant feature compared to the Susumu parts.
