Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-3403-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 340 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: minimum 0.125W (equal or higher acceptable)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• Anti-sulfur construction (exact match required)
• RoHS3 compliance (exact match required)

Tolerance Substitution Logic: The RG2012N-3403-C-T5 specifies ±0.25% tolerance. Substitute parts with equal or tighter (lower) tolerance values are functionally equivalent and directly interchangeable. Parts with tighter tolerance specifications (±0.1% or ±0.05%) provide enhanced precision performance while maintaining full backward compatibility.

Operating Temperature Range: The main part operates from -55°C to 155°C. Substitute parts with equal or extended upper temperature limits are acceptable.

Packaging Format: All substitute parts are supplied in Tape & Reel (TR) format, which is compatible with automated assembly processes equivalent to the original packaging specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-3403-B-T5, RG2012N-3403-W-T5, and RG2012N-3403-W-T1 are direct substitutes manufactured by Susumu within the same RG series. All three parts maintain identical electrical and mechanical specifications to the main part with the exception of tolerance specifications. These parts are currently in active production status, ensuring long-term availability and supply chain continuity.

RG2012N-3403-B-T5 provides ±0.1% tolerance, representing a one-step improvement in precision over the original ±0.25% specification while maintaining identical power rating and package dimensions.

RG2012N-3403-W-T5 and RG2012N-3403-W-T1 both provide ±0.05% tolerance, representing the highest precision option within the Susumu RG series. Both variants are functionally equivalent with identical electrical performance characteristics. The distinction between these two parts relates to packaging tape specifications (T5 versus T1 reel formats), which do not affect component performance or compatibility.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805340KBYEA manufactured by Vishay Dale provides an alternative source for 340 kOhms 0805 thin film resistors with AEC-Q200 automotive qualification. This part features ±0.1% tolerance and an enhanced power rating of 0.26W, providing additional thermal margin compared to the 0.125W specification of the original part. The operating temperature range extends to 175°C, exceeding the original -55°C to 155°C specification. Moisture-resistant construction is included as an additional feature. All other critical parameters including resistance value, package type, temperature coefficient, and automotive ratings remain equivalent.

Procurement Guidance:

For applications requiring direct replacement with identical specifications, RG2012N-3403-B-T5 is recommended as the primary substitute, offering improved tolerance performance while maintaining all other original specifications.

For applications where enhanced precision is beneficial, RG2012N-3403-W-T5 or RG2012N-3403-W-T1 provide ±0.05% tolerance performance.

For applications requiring cross-manufacturer sourcing or enhanced thermal performance, TNPW0805340KBYEA provides equivalent functionality with additional performance margin.

All substitute parts maintain full compliance with automotive AEC-Q200 standards, RoHS3 regulations, and anti-sulfur construction requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-3403-B-T5 be used as a direct replacement for RG2012N-3403-C-T5?

A: Yes. The RG2012N-3403-B-T5 is a direct substitute. Both parts share identical resistance (340 kOhms), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The RG2012N-3403-B-T5 provides tighter tolerance (±0.1% versus ±0.25%), which represents improved precision performance and maintains full backward compatibility.

Q: What is the difference between RG2012N-3403-W-T5 and RG2012N-3403-W-T1?

A: Both parts are electrically and mechanically identical with 340 kOhms resistance, ±0.05% tolerance, 0.125W power rating, and 0805 package. The designation difference (T5 versus T1) refers to the tape reel format used for packaging and automated assembly. Both formats are compatible with standard pick-and-place equipment. Selection between these variants depends on existing assembly line tape specifications and inventory management practices.

Q: Is TNPW0805340KBYEA compatible with the original RG2012N-3403-C-T5?

A: Yes. The TNPW0805340KBYEA is compatible as a substitute. Both parts share 340 kOhms resistance, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The Vishay Dale part provides enhanced specifications including ±0.1% tolerance (tighter than the original ±0.25%), 0.26W power rating (higher than the original 0.125W), and extended operating temperature to 175°C (versus 155°C). These enhancements provide additional performance margin without compromising compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RG2012N-3403-B-T5, RG2012N-3403-W-T5, RG2012N-3403-W-T1, and TNPW0805340KBYEA) are RoHS3 compliant, matching the compliance status of the original RG2012N-3403-C-T5.

Q: Can these 0805 resistors be used in applications requiring higher power dissipation?

A: The original RG2012N-3403-C-T5 is rated for 0.125W power dissipation. The Susumu substitutes (RG2012N-3403-B-T5, RG2012N-3403-W-T5, RG2012N-3403-W-T1) maintain this 0.125W rating. The Vishay Dale TNPW0805340KBYEA provides a higher 0.26W rating, suitable for applications requiring increased thermal performance. For applications exceeding these power specifications, larger package sizes must be evaluated.

Q: What is the moisture sensitivity level for these resistors?

A: All listed parts, including the original and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these parts suitable for automotive applications?

A: Yes. All parts including the original RG2012N-3403-C-T5 and all substitutes carry AEC-Q200 automotive qualification, confirming suitability for automotive applications. Anti-sulfur construction is included in all variants, providing protection against sulfur-containing environments common in automotive applications.

Q: What is the physical size difference between the main part and substitutes?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height is 0.020" (0.50mm) for Susumu parts and 0.022" (0.55mm) for the Vishay Dale part. These minimal height differences do not affect PCB layout or assembly compatibility.
