Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-2492-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24.9 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• Anti-Sulfur feature
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Temperature coefficient: ±10ppm/°C or ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C or extended to -55°C ~ 175°C
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Active preferred over obsolete

Substitute parts must maintain electrical equivalence through identical resistance and tolerance specifications, or provide improved tolerance performance. Physical package dimensions and thermal characteristics must remain compatible with the original design footprint and thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications):

RG2012N-2492-B-T5 provides direct electrical equivalence to the RG2012N-2492-B-T1 with identical resistance, tolerance, power rating, and temperature coefficient. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk). This part is recommended for immediate substitution in new procurement activities.

Equivalent with Relaxed Temperature Coefficient:

RG2012P-2492-B-T5 maintains all critical electrical parameters with the exception of temperature coefficient (±25ppm/°C vs. ±10ppm/°C). This part is suitable for applications where the relaxed temperature coefficient specification does not compromise circuit performance. Active product status and high inventory availability support production continuity.

Upgraded Tolerance Performance:

RG2012N-2492-W-T1 and RG2012N-2492-W-T5 provide improved tolerance specification (±0.05% vs. ±0.1%) while maintaining all other electrical and thermal characteristics. These parts are suitable for designs requiring enhanced precision and are available in both bulk and tape & reel packaging formats.

Cross-Manufacturer Alternative:

TNPW080524K9BYEA (Vishay Dale) offers equivalent electrical specifications with enhanced power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). This part is suitable for applications requiring thermal margin or higher power dissipation capability. All parts maintain AEC-Q200 automotive qualification, anti-sulfur construction, and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2492-B-T5 be used as a direct replacement for RG2012N-2492-B-T1?

A: Yes. RG2012N-2492-B-T5 is electrically and mechanically equivalent. The difference is packaging format (Tape & Reel vs. Bulk) and product status (Active vs. Obsolete). Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

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

A: The primary difference is temperature coefficient specification. RG2012N series has ±10ppm/°C, while RG2012P series has ±25ppm/°C. Both maintain identical resistance, tolerance, and power ratings. Selection depends on circuit requirements for temperature stability.

Q: Are the W-series parts (RG2012N-2492-W-T1 and RG2012N-2492-W-T5) compatible with the original design?

A: Yes. The W-series parts provide improved tolerance (±0.05% vs. ±0.1%) and are mechanically and thermally compatible. The tighter tolerance represents an upgrade in precision performance. All other electrical and thermal specifications remain identical.

Q: What are the advantages of TNPW080524K9BYEA over Susumu equivalents?

A: TNPW080524K9BYEA offers higher power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). These features provide additional thermal margin and capability for higher power dissipation applications. Electrical specifications (resistance, tolerance, temperature coefficient) remain equivalent.

Q: Does packaging format (Bulk vs. Tape & Reel) affect electrical performance?

A: No. Packaging format does not affect electrical or thermal performance. The difference is in handling, storage, and assembly process compatibility. Bulk packaging is suitable for manual assembly or small-volume applications, while Tape & Reel format is standard for automated pick-and-place assembly.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts maintain automotive AEC-Q200 qualification, anti-sulfur construction, RoHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with automotive and high-reliability applications.
