Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-394-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 390 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Automotive AEC-Q200 rating (exact match required)
• RoHS3 compliance (exact match required)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter (lower) than ±0.25%
• Power rating: Can be equal to or higher than 0.125W
• Operating temperature range: Can be equal to or wider than -55°C ~ 155°C
• Packaging format: Tape & Reel (TR) acceptable for equivalent function

All substitute parts listed maintain identical resistance, package, composition, temperature coefficient, and automotive qualification. Tolerance improvements and power rating increases represent upgrades that maintain full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-394-B-T5, RG2012N-394-W-T5, and RG2012N-394-W-T1 are direct Susumu equivalents with improved tolerance specifications. All three maintain identical resistance, package, composition, temperature coefficient, and automotive AEC-Q200 qualification. These parts are currently in active production status, ensuring long-term availability and supply chain continuity. The RG2012N-394-B-T5 offers ±0.1% tolerance, while both RG2012N-394-W-T5 and RG2012N-394-W-T1 provide ±0.05% tolerance, representing tighter tolerance upgrades suitable for precision circuit applications.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805390KBYEA from Vishay Dale provides an alternative from a different manufacturer while maintaining all critical electrical and mechanical parameters. This part features a higher power rating of 0.26W and an extended operating temperature range to 175°C. The TNPW0805390KBYEA includes moisture-resistant coating in addition to anti-sulfur protection. This component is suitable for applications requiring enhanced thermal performance or extended temperature operation within automotive environments.

Selection Criteria:

• For direct Susumu product line continuity: Select RG2012N-394-B-T5 or RG2012N-394-W-T1/W-T5
• For enhanced thermal margin: Select TNPW0805390KBYEA
• For tightest tolerance requirement: Select RG2012N-394-W-T1 or RG2012N-394-W-T5
• All substitutes maintain full compliance with RoHS3, REACH, and automotive AEC-Q200 requirements

Frequently Asked Questions (FAQ)

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

A: Yes. The RG2012N-394-B-T5 maintains identical resistance (390 kOhms), package (0805), composition (thin film), temperature coefficient (±10ppm/°C), and automotive AEC-Q200 qualification. The tolerance is improved from ±0.25% to ±0.1%, which is a tighter specification that maintains backward compatibility.

Q: What is the difference between RG2012N-394-W-T5 and RG2012N-394-W-T1?

A: Both parts are identical in all electrical and mechanical specifications. The difference is in packaging format: RG2012N-394-W-T5 uses Tape & Reel (TR) packaging with one reel configuration, while RG2012N-394-W-T1 uses Tape & Reel (TR) packaging with a different reel configuration. Both provide ±0.05% tolerance and are suitable for automated assembly processes.

Q: Why does TNPW0805390KBYEA have a higher power rating (0.26W vs 0.125W)?

A: The TNPW0805390KBYEA from Vishay Dale is rated for 0.26W power dissipation, which is higher than the original 0.125W specification. This higher power rating does not affect substitution compatibility; it represents an upgrade that provides additional thermal margin in applications where power dissipation approaches the original specification limit.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts—RG2012N-394-B-T5, RG2012N-394-W-T5, RG2012N-394-W-T1, and TNPW0805390KBYEA—carry automotive AEC-Q200 qualification and are suitable for automotive applications.

Q: What is the physical compatibility of these parts in existing PCB designs?

A: All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). The TNPW0805390KBYEA has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for Susumu parts, which remains within standard PCB assembly tolerances and does not require design modification.

Q: Is the RG2012N-394-C-T5 still available for procurement?

A: The RG2012N-394-C-T5 is classified as obsolete. Active production alternatives include RG2012N-394-B-T5, RG2012N-394-W-T5, RG2012N-394-W-T1, and TNPW0805390KBYEA, all of which are in active production status and available for new designs and ongoing procurement.

Q: Can tolerance be relaxed when substituting with a tighter tolerance part?

A: Yes. Substituting with a tighter tolerance part (lower tolerance value) is fully compatible. For example, using RG2012N-394-W-T1 (±0.05%) in place of RG2012N-394-C-T5 (±0.25%) provides improved accuracy without affecting circuit functionality or requiring design changes.

Q: What is the operating temperature difference between substitutes?

A: The RG2012N-394-C-T5, RG2012N-394-B-T5, RG2012N-394-W-T5, and RG2012N-394-W-T1 operate from -55°C to 155°C. The TNPW0805390KBYEA extends the upper limit to 175°C, providing 20°C additional thermal headroom for high-temperature automotive applications.
