Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-1823-B-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 182 kOhms
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Operating temperature range: Must encompass -55°C ~ 155°C minimum
• Temperature coefficient: ±10ppm/°C
• Packaging format: Tape & Reel (TR) acceptable for obsolete part replacement

Substitute parts are grouped into two categories: direct equivalents (identical electrical specifications) and upgrades (improved tolerance or power rating while maintaining all other critical parameters).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications):

RG2012N-1823-B-T5 is the direct equivalent to RG2012N-1823-B-T1. Both components share identical electrical parameters: 182 kOhms resistance, ±0.1% tolerance, 0.125W power rating, and ±10ppm/°C temperature coefficient. The primary difference is packaging format (Tape & Reel versus bulk). RG2012N-1823-B-T5 maintains active product status and full AEC-Q200 automotive qualification.

Upgraded Alternatives (Improved Tolerance):

RG2012N-1823-W-T1 and RG2012N-1823-W-T5 provide tighter tolerance specification (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. Both are active Susumu products with full AEC-Q200 compliance. Selection between T1 and T5 variants depends on packaging requirements (bulk versus Tape & Reel).

Cross-Manufacturer Alternative (Enhanced Power Rating):

TNPW0805182KBYEA (Vishay Dale) offers increased power dissipation capability (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This component maintains ±0.1% tolerance, AEC-Q200 qualification, and anti-sulfur construction. The higher power rating accommodates applications with greater thermal stress while preserving all critical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-1823-B-T5 be used as a direct replacement for RG2012N-1823-B-T1?

A: Yes. RG2012N-1823-B-T5 is electrically and mechanically identical to RG2012N-1823-B-T1. Both components specify 182 kOhms ±0.1%, 0.125W power rating, 0805 package, and AEC-Q200 qualification. The difference is packaging format (Tape & Reel versus bulk). Electrical performance and circuit compatibility are equivalent.

Q: What is the advantage of selecting RG2012N-1823-W-T1 or RG2012N-1823-W-T5?

A: These variants provide ±0.05% tolerance compared to ±0.1% in the original part. This tighter tolerance reduces resistor value variation in precision circuits. All other parameters remain identical, including power rating, package, and temperature coefficient. Selection is appropriate for applications requiring improved accuracy.

Q: When should TNPW0805182KBYEA be selected over Susumu alternatives?

A: TNPW0805182KBYEA is selected when circuit design requires higher power dissipation (0.26W versus 0.125W) or extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The component maintains ±0.1% tolerance and AEC-Q200 qualification. Physical dimensions remain compatible with 0805 package footprints.

Q: Are all substitute parts RoHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitute parts are ROHS3 compliant and carry AEC-Q200 automotive qualification. Moisture Sensitivity Level is 1 (Unlimited) for all components, indicating no special handling requirements during storage or assembly.

Q: What is the difference between T1 and T5 packaging designations?

A: T1 and T5 designations indicate different tape reel specifications within Tape & Reel (TR) packaging format. Both are suitable for automated assembly processes. Selection depends on equipment compatibility and procurement specifications. Electrical and mechanical performance are identical between T1 and T5 variants.

Q: Can the 0805 package dimension (2.00mm x 1.25mm) accommodate all substitute parts on existing PCB layouts?

A: Yes. All substitute parts conform to 0805 (2012 Metric) package dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm). Maximum seated height is 0.020" (0.50mm) for Susumu parts and 0.022" (0.55mm) for TNPW0805182KBYEA. These dimensions are within standard 0805 package tolerance and compatible with existing PCB footprints.
