Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-4872-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 48.7 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 rating
• Anti-Sulfur feature
• RoHS3 compliance
• Moisture Sensitivity Level: 1

Allowable Variation Parameters:

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

Substitute parts meeting these criteria provide direct functional equivalence with identical mechanical fit and electrical performance within specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer, Active Status):

RG2012N-4872-B-T5 provides direct substitution for the obsolete RG2012N-4872-B-T1. Both parts maintain identical electrical specifications, package dimensions, and automotive compliance. The primary difference is packaging format (Tape & Reel) and active product status, making this the preferred replacement for new designs and production continuity.

Upgraded Tolerance Alternative (Same Manufacturer, Active Status):

RG2012N-4872-W-T1 and RG2012N-4872-W-T5 offer tighter tolerance specification (±0.05% versus ±0.1%), providing enhanced precision for applications requiring improved resistance accuracy. These parts maintain all other electrical and mechanical parameters, with active product status ensuring long-term availability. Selection between T1 and T5 variants depends on packaging requirements.

Cross-Manufacturer Alternative (Extended Temperature Range):

TNPW080548K7BYEA from Vishay Dale provides functional equivalence with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). This part maintains ±0.1% tolerance, anti-sulfur construction, and AEC-Q200 automotive qualification. The increased power rating and temperature range support applications with higher thermal demands while maintaining mechanical compatibility in 0805 package format.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and automotive-grade reliability standards required for the original component application.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-4872-B-T5 directly replace RG2012N-4872-B-T1 in existing designs?

A: Yes. RG2012N-4872-B-T5 provides direct functional replacement with identical resistance value (48.7 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). The primary difference is packaging format (Tape & Reel) and active product status. Electrical performance and mechanical fit are equivalent.

Q: What is the difference between the W-series (RG2012N-4872-W-T1, RG2012N-4872-W-T5) and the B-series parts?

A: The W-series parts feature tighter tolerance specification (±0.05% versus ±0.1%). All other parameters including resistance value, power rating, package, temperature coefficient, and operating temperature range remain identical. Selection depends on application precision requirements.

Q: Is TNPW080548K7BYEA from Vishay Dale compatible with the original Susumu part?

A: TNPW080548K7BYEA provides functional equivalence with identical resistance value (48.7 kOhms), tolerance (±0.1%), package (0805), and temperature coefficient (±10ppm/°C). The part features enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). Mechanical fit is identical. Cross-manufacturer substitution is valid for applications within the original operating specifications.

Q: What does the T1 and T5 designation indicate in the part numbers?

A: The T1 and T5 designations indicate different packaging tape specifications within Tape & Reel format. Both provide identical electrical and mechanical performance. Selection depends on equipment compatibility with specific tape configurations.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed maintain automotive AEC-Q200 qualification, anti-sulfur construction, and ROHS3 compliance, ensuring compatibility with automotive and high-reliability applications.

Q: Can I use a higher power-rated part (TNPW080548K7BYEA at 0.26W) in place of the 0.125W original?

A: Yes. The TNPW080548K7BYEA with 0.26W power rating is suitable for applications originally specified for 0.125W. Higher power rating provides additional thermal margin and does not affect electrical performance or mechanical fit in 0805 package format.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
