Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1608V-3740-C-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 374 Ohms
• Package / Case: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

Variable Parameter (Tolerance Grade):

• Tolerance: Substitute parts offer tighter tolerance grades (±0.1%, ±0.05%, ±0.02%) compared to the original ±0.25% specification. Tighter tolerances are electrically compatible with applications designed for ±0.25% tolerance.

All substitute parts listed maintain identical mechanical dimensions, thermal characteristics, and automotive qualification ratings. Substitution is valid for direct board-level replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RG1608V-3740-B-T5

The RG1608V-3740-W-T1 provides ±0.05% tolerance with the highest inventory availability (1109 Pcs in stock). This part is suitable for applications requiring enhanced precision while maintaining full compatibility with the original design specifications. Active product status ensures long-term supply continuity.

Tertiary Substitute: RG1608V-3740-P-T1

The RG1608V-3740-P-T1 delivers the tightest tolerance grade at ±0.02% with active product status and strong inventory levels (822 Pcs in stock). This part is appropriate for precision measurement circuits or applications where maximum resistance accuracy is required within the 374 Ohms specification.

All substitute parts maintain identical mechanical fit, thermal performance, and automotive qualification ratings. Selection among substitutes depends on tolerance requirements and supply chain preferences. No circuit modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can RG1608V-3740-B-T5, RG1608V-3740-W-T1, and RG1608V-3740-P-T1 be used interchangeably with RG1608V-3740-C-T5?

A: Yes. All substitute parts maintain identical resistance values (374 Ohms), package dimensions (0603 / 1608 Metric), power ratings (0.1W), and automotive AEC-Q200 qualifications. The substitute parts offer tighter tolerance grades, which are electrically compatible with applications designed for the original ±0.25% tolerance specification. Direct board-level replacement is valid without circuit redesign.

Q: What is the difference between the tolerance grades of the substitute parts?

A: The substitute parts differ only in tolerance specification: RG1608V-3740-B-T5 offers ±0.1%, RG1608V-3740-W-T1 offers ±0.05%, and RG1608V-3740-P-T1 offers ±0.02%. All other electrical and mechanical parameters remain identical. Tighter tolerance grades provide improved resistance accuracy and are suitable for precision applications.

Q: Are all substitute parts available in the same packaging format?

A: The main part RG1608V-3740-C-T5 is supplied in standard packaging. All substitute parts (RG1608V-3740-B-T5, RG1608V-3740-W-T1, RG1608V-3740-P-T1) are supplied in Tape & Reel (TR) format, which is the standard packaging for high-volume production environments.

Q: Do the substitute parts maintain the same temperature coefficient and operating temperature range?

A: Yes. All substitute parts maintain the identical temperature coefficient of ±5ppm/°C and operating temperature range of -55°C to 155°C. Thermal performance characteristics are unchanged across all substitute options.

Q: Are all substitute parts RoHS3 compliant and MSL 1 rated?

A: Yes. All substitute parts (RG1608V-3740-B-T5, RG1608V-3740-W-T1, RG1608V-3740-P-T1) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original part.

Q: Why is the original RG1608V-3740-C-T5 classified as obsolete?

A: The RG1608V-3740-C-T5 is classified as obsolete, indicating discontinued production. The listed substitute parts with active product status provide equivalent functionality with improved tolerance specifications and assured long-term supply availability.

Q: Which substitute part should be selected for new designs?

A: For new designs, any of the three active substitute parts (RG1608V-3740-B-T5, RG1608V-3740-W-T1, or RG1608V-3740-P-T1) is appropriate. Selection depends on tolerance requirements and supply chain preferences. All parts maintain identical mechanical and thermal characteristics suitable for automotive applications.
