Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-8252-B-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 82.5 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 rating
• Anti-Sulfur feature
• RoHS3 compliance
• Moisture Sensitivity Level 1

Variable Parameters Allowing Substitution:

• Tolerance: ±0.1% (main part) to ±0.05% (upgrade options)
• Power Rating: 0.125W (main part) to 0.26W (upgrade option)
• Temperature Coefficient: ±10ppm/°C (main part) to ±25ppm/°C (similar option)
• Operating Temperature Range: -55°C ~ 155°C (main part) to -55°C ~ 175°C (upgrade option)
• Packaging format: Bulk to Tape & Reel (TR)
• Product Status: Obsolete (main part) to Active (all substitutes)

Substitutes are grouped into three categories: Direct equivalents (identical electrical specifications with different packaging), upgrades (improved tolerance or power rating), and similar parts (minor parameter variations within acceptable ranges).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended for Drop-In Replacement):

RG2012N-8252-B-T5 provides identical electrical and mechanical specifications to the RG2012N-8252-B-T1, with the primary difference being packaging format (Tape & Reel versus bulk). This part maintains active product status with Susumu, ensuring long-term availability and supply chain stability. Selection of this part requires no circuit re-evaluation.

Upgrade Options (Enhanced Performance):

RG2012N-8252-W-T1 and RG2012N-8252-W-T5 offer improved tolerance specification (±0.05% versus ±0.1%), providing tighter resistance accuracy for precision circuit applications. Both parts maintain identical power rating, temperature coefficient, and operating temperature range. These upgrades are suitable for designs requiring enhanced tolerance performance without thermal or power dissipation modifications.

Alternative Manufacturer Option (Cross-Manufacturer Substitute):

TNPW080582K5BYEA (Vishay Dale) provides equivalent resistance and tolerance with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This part introduces cross-manufacturer sourcing capability while maintaining AEC-Q200 automotive qualification and RoHS3 compliance. The increased power rating accommodates higher dissipation environments without package size change.

Similar Part (Tolerance Trade-off):

RG2012P-8252-B-T5 maintains identical resistance, tolerance, and power rating with a higher temperature coefficient specification (±25ppm/°C versus ±10ppm/°C). This part is suitable for applications where temperature coefficient drift is not a critical design parameter. The significantly higher inventory level (11,514 pieces) provides immediate availability advantage.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-8252-B-T5 be used as a direct replacement for RG2012N-8252-B-T1?

A: Yes. RG2012N-8252-B-T5 is electrically and mechanically identical to the main part. The only difference is packaging format (Tape & Reel versus bulk). No circuit modifications are required for substitution.

Q: What is the advantage of selecting RG2012N-8252-W-T1 or RG2012N-8252-W-T5 over the direct equivalent?

A: These parts offer improved tolerance specification (±0.05% versus ±0.1%), resulting in tighter resistance accuracy. Selection is appropriate for precision analog circuits, reference networks, or measurement applications where tolerance performance directly impacts circuit accuracy.

Q: Is TNPW080582K5BYEA compatible with the original design?

A: TNPW080582K5BYEA is compatible from an electrical and mechanical standpoint. The part maintains 82.5 kOhms resistance, ±0.1% tolerance, 0805 package, and AEC-Q200 qualification. The increased power rating (0.26W) and extended temperature range (-55°C ~ 175°C) represent performance enhancements. Cross-manufacturer sourcing may require supply chain qualification per your procurement standards.

Q: What is the significance of the packaging designation (T1 versus T5)?

A: T1 and T5 designations refer to packaging format and reel specifications. T1 typically indicates standard packaging, while T5 indicates Tape & Reel format. Both formats contain identical components; packaging selection depends on assembly process requirements and inventory management practices.

Q: Why does RG2012P-8252-B-T5 have a different temperature coefficient (±25ppm/°C)?

A: The RG2012P series represents a different product line within Susumu's resistor portfolio. The higher temperature coefficient reflects different thin film construction or material composition. This part is suitable for applications where temperature coefficient stability is not a critical design requirement.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed maintain automotive AEC-Q200 qualification, ensuring compliance with automotive reliability and quality standards. All parts are RoHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited shelf life).

Q: Can I use RG2012P-8252-B-T5 in a precision measurement circuit?

A: RG2012P-8252-B-T5 maintains ±0.1% tolerance matching the original part. However, the higher temperature coefficient (±25ppm/°C versus ±10ppm/°C) may introduce greater resistance drift across temperature variations. For precision measurement applications sensitive to temperature-induced drift, RG2012N-8252-W-T1 or RG2012N-8252-W-T5 are preferred selections.

Q: What inventory considerations should guide part selection?

A: RG2012P-8252-B-T5 offers the highest inventory availability (11,514 pieces), providing immediate procurement advantage. RG2012N-8252-W-T5 (875 pieces) and RG2012N-8252-B-T5 (770 pieces) provide adequate stock for standard production volumes. TNPW080582K5BYEA (772 pieces) offers cross-manufacturer sourcing with comparable availability.
