Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-124-D-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 120 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameter:

• Tolerance: The substitute part RG2012N-124-W-T1 features ±0.05% tolerance, which is tighter (more stringent) than the ±0.5% specification of the main part. Tighter tolerance specifications are electrically and mechanically compatible with applications designed for the original tolerance.

The identified substitute maintains all electrical characteristics, mechanical dimensions, thermal properties, and automotive qualification requirements while offering improved tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012N-124-D-T5 and RG2012N-124-W-T1 are active production components manufactured by Susumi with full automotive AEC-Q200 qualification. Both parts comply with ROHS3 requirements and carry unlimited moisture sensitivity rating (MSL 1).

The RG2012N-124-W-T1 substitute provides identical electrical performance and mechanical compatibility with the added benefit of tighter tolerance specification (±0.05% versus ±0.5%). This enhanced tolerance characteristic makes the substitute suitable for applications where the original part is unavailable or where improved precision is required without design modification.

Selection between these parts should be based on application tolerance requirements and component availability. The substitute part is directly interchangeable from a mechanical and thermal standpoint, with superior tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-124-W-T1 be used as a direct replacement for RG2012N-124-D-T5?

A: Yes. Both parts share identical resistance value (120 kOhms), package (0805), power rating (0.125W), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 qualification. The substitute features tighter tolerance (±0.05% versus ±0.5%), which is compatible with applications designed for the original part.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. RG2012N-124-D-T5 carries ±0.5% tolerance, while RG2012N-124-W-T1 carries ±0.05% tolerance. All other electrical, mechanical, and compliance characteristics are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0805 (2012 Metric) with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet automotive standards?

A: Yes. Both RG2012N-124-D-T5 and RG2012N-124-W-T1 carry AEC-Q200 automotive qualification and are ROHS3 compliant.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can the substitute part be used in high-precision applications?

A: The RG2012N-124-W-T1 substitute with ±0.05% tolerance is suitable for applications requiring higher precision than the original ±0.5% specification. The tighter tolerance provides improved accuracy for precision circuit designs.
