• Automotive Rating: AEC-Q200 (exact match required)
• Anti-Sulfur feature (exact match required)
• RoHS3 Compliance (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

Parameters Allowed to Improve:

• Tolerance: May decrease (improve) from ±0.25% to ±0.1% or ±0.05%
• Power Rating: May increase from 0.125W to higher values
• Operating Temperature Range: May extend to higher maximum temperatures
• Product Status: Active status preferred over obsolete

All substitute parts listed maintain identical mechanical dimensions, termination count, and regulatory compliance while offering equal or superior electrical performance.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-1403-B-T5, RG2012N-1403-W-T1, and RG2012N-1403-W-T5 are direct Susumu equivalents maintaining identical electrical specifications while offering improved tolerance performance. All three parts are active products with AEC-Q200 automotive qualification and anti-sulfur construction. The RG2012N-1403-W-T1 and RG2012N-1403-W-T5 provide the highest tolerance specification at ±0.05%, suitable for precision applications. The RG2012N-1403-B-T5 offers ±0.1% tolerance as an intermediate option. All Susumu substitutes maintain the same 0.125W power rating and -55°C ~ 155°C operating temperature range.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805140KBYEA from Vishay Dale provides an alternative from a different manufacturer while maintaining all critical compatibility parameters. This part offers enhanced power rating capability at 0.26W and extended operating temperature range to 175°C. The ±0.1% tolerance and AEC-Q200 rating ensure automotive application compatibility. The TNPW0805140KBYEA is suitable for applications requiring higher thermal headroom or extended temperature operation.

Selection Criteria:

• For direct Susumu product line continuation: Select RG2012N-1403-W-T5 (highest inventory, ±0.05% tolerance, active status)
• For tolerance-critical applications: Select RG2012N-1403-W-T1 or RG2012N-1403-W-T5 (±0.05% tolerance)
• For cross-manufacturer compatibility: Select TNPW0805140KBYEA (Vishay Dale, extended temperature range)
• For cost-optimized selection with acceptable tolerance: Select RG2012N-1403-B-T5 (±0.1% tolerance)

All substitute parts are RoHS3 compliant with MSL 1 rating and maintain identical mechanical footprint and electrical characteristics required for direct PCB replacement.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-1403-C-T5 be replaced with any of the listed substitutes?

A: Yes. All listed substitutes maintain identical resistance value (140 kOhms), package type (0805), composition (thin film), temperature coefficient (±10ppm/°C), AEC-Q200 rating, anti-sulfur construction, and RoHS3 compliance. The substitutes offer equal or improved tolerance specifications and are electrically and mechanically compatible for direct PCB replacement.

Q: What is the difference between the Susumu RG substitutes?

A: The three Susumu RG substitutes differ in tolerance specification: RG2012N-1403-B-T5 provides ±0.1% tolerance, while RG2012N-1403-W-T1 and RG2012N-1403-W-T5 provide ±0.05% tolerance. All three maintain identical power rating (0.125W), operating temperature range (-55°C ~ 155°C), and automotive qualification. The primary difference is tolerance performance, with the W-series parts offering superior precision.

Q: How does the Vishay Dale TNPW0805140KBYEA differ from the Susumu options?

A: The TNPW0805140KBYEA offers two key enhancements: increased power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). Tolerance is ±0.1%, matching the RG2012N-1403-B-T5. All other electrical and mechanical parameters remain compatible. The higher power rating provides additional thermal margin in applications with higher current or power dissipation requirements.

Q: Are all substitutes available in the same packaging format?

A: The original RG2012N-1403-C-T5 is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The physical component dimensions and footprint remain identical across all parts, ensuring direct PCB compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs, select from the active product options: RG2012N-1403-W-T5 (Susumu, ±0.05% tolerance, highest inventory) or TNPW0805140KBYEA (Vishay Dale, extended temperature range). Both are active products with full AEC-Q200 automotive qualification. Selection depends on tolerance requirements and thermal operating conditions of the specific application.

Q: Is the tolerance improvement from ±0.25% to ±0.05% significant for circuit operation?

A: Tolerance improvement is application-dependent. For precision analog circuits, voltage dividers, or reference networks, the reduction from ±0.25% to ±0.05% tolerance provides four-fold improvement in resistor accuracy. For general-purpose applications with wide tolerance budgets, the improvement may not be critical. Evaluate circuit design requirements to determine if tolerance upgrade is necessary.

Q: Can the TNPW0805140KBYEA be used in applications designed for the RG2012N-1403-C-T5?

A: Yes. The TNPW0805140KBYEA maintains all critical electrical parameters (140 kOhms, ±10ppm/°C, AEC-Q200, anti-sulfur, thin film) and identical package dimensions. The enhanced power rating (0.26W) and extended temperature range (to 175°C) provide additional design margin without compromising compatibility. Direct substitution is electrically and mechanically valid.
