Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-394-B-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 390 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 rating
• Anti-Sulfur construction
• 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 or higher maximum
• Temperature coefficient: ±10ppm/°C

Substitute parts are grouped into two categories: direct equivalents (matching all electrical specifications) and upgrades (enhanced tolerance or power rating specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications):

RG2012N-394-B-T5 is the direct equivalent to RG2012N-394-B-T1. Both components share identical electrical specifications: 390 kOhms resistance, ±0.1% tolerance, 0.125W power rating, and ±10ppm/°C temperature coefficient. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. RG2012N-394-B-T5 is recommended as the primary replacement for obsolete RG2012N-394-B-T1 applications.

Upgraded Specifications (Enhanced Tolerance):

RG2012N-394-W-T1 and RG2012N-394-W-T5 offer tighter tolerance specifications (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. These Susumu components are suitable for applications requiring higher precision resistor values. Both are available in Tape & Reel packaging and carry active product status.

Alternative Manufacturer (Enhanced Power Rating):

TNPW0805390KBYEA from Vishay Dale provides a higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). This component maintains ±0.1% tolerance and all automotive AEC-Q200 certifications. The increased power dissipation capability and higher maximum operating temperature make this suitable for applications with elevated thermal requirements.

All substitute parts maintain mechanical compatibility through identical 0805 (2012 Metric) package dimensions, anti-sulfur construction, AEC-Q200 automotive qualification, and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-394-B-T5 be used as a direct replacement for RG2012N-394-B-T1?

A: Yes. RG2012N-394-B-T5 is electrically and mechanically identical to RG2012N-394-B-T1. Both components have 390 kOhms resistance, ±0.1% tolerance, 0.125W power rating, and identical package dimensions. The difference is packaging format and product status (active versus obsolete).

Q: What is the difference between the Susumu RG2012N-394-W series and the RG2012N-394-B series?

A: The primary difference is tolerance specification. The RG2012N-394-W series offers ±0.05% tolerance, while the RG2012N-394-B series offers ±0.1% tolerance. All other electrical and mechanical parameters remain identical. Selection depends on circuit precision requirements.

Q: Is the Vishay Dale TNPW0805390KBYEA compatible with the original RG2012N-394-B-T1?

A: TNPW0805390KBYEA is mechanically and electrically compatible for most applications. It shares the same 0805 package, 390 kOhms resistance, ±0.1% tolerance, and AEC-Q200 automotive rating. The key differences are higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). These enhancements make it suitable for higher thermal stress environments.

Q: Are all substitute parts available in Tape & Reel packaging?

A: RG2012N-394-B-T5, RG2012N-394-W-T1, RG2012N-394-W-T5, and TNPW0805390KBYEA are all supplied in Tape & Reel (TR) packaging. The original RG2012N-394-B-T1 was supplied in bulk packaging.

Q: Do all substitute parts meet automotive AEC-Q200 requirements?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification and anti-sulfur construction, maintaining compliance with automotive industry standards.

Q: What is the significance of the temperature coefficient specification?

A: The ±10ppm/°C temperature coefficient indicates the resistor's resistance change per degree Celsius across the operating temperature range. All listed parts share this specification, ensuring consistent thermal performance characteristics.

Q: Can the higher power-rated TNPW0805390KBYEA be used in place of the 0.125W rated RG2012N-394-B-T1?

A: Yes. A higher power-rated component can be substituted in applications designed for lower power dissipation. The 0.26W rating of TNPW0805390KBYEA provides additional thermal margin and is mechanically compatible with the 0805 package footprint.
