Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG3216V-6491-C-T5 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 6.49 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (physical and electrical compatibility)
• Power rating: 0.25W (1/4W) (thermal and electrical performance)
• Composition: Thin Film (electrical characteristics and stability)
• Temperature coefficient: ±5ppm/°C (thermal stability)
• Operating temperature range: -55°C ~ 155°C (environmental performance)
• Automotive AEC-Q200 rating (quality and reliability standards)
• Anti-sulfur construction (environmental resistance)

Variable Parameter (Substitution Basis):

• Tolerance: The substitute parts offer improved tolerance specifications (±0.1%, ±0.05%, ±0.02%) compared to the original ±0.25%. These represent performance upgrades while maintaining full backward compatibility.

All substitute parts are active products with current manufacturing status, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RG3216V-6491-P-T1

The RG3216V-6491-P-T1 offers the highest tolerance specification at ±0.02%, providing superior precision for applications requiring tight resistance value control. This part maintains full electrical and mechanical compatibility with the obsolete RG3216V-6491-C-T5 while delivering enhanced performance. Active product status ensures long-term availability and supply chain reliability.

Secondary Recommendation: RG3216V-6491-W-T1

The RG3216V-6491-W-T1 provides ±0.05% tolerance, representing a balanced upgrade path for applications where moderate precision improvement is required. This part is suitable for general-purpose automotive applications while maintaining all AEC-Q200 and anti-sulfur specifications.

Tertiary Recommendation: RG3216V-6491-B-T5

The RG3216V-6491-B-T5 delivers ±0.1% tolerance, offering a cost-effective upgrade from the obsolete part. This option is appropriate for applications where the original ±0.25% tolerance was acceptable but improved performance is desired.

All three substitute parts are manufactured by Susumu, maintain identical electrical characteristics (temperature coefficient, operating temperature range), and carry equivalent automotive-grade certifications. Selection among these alternatives depends on application-specific tolerance requirements and performance specifications.

Frequently Asked Questions (FAQ)

Q: Can RG3216V-6491-P-T1, RG3216V-6491-B-T5, or RG3216V-6491-W-T1 be used as direct replacements for RG3216V-6491-C-T5?

A: Yes. All three substitute parts are direct replacements. They share identical resistance values (6.49 kOhms), package dimensions (1206/3216 Metric), power ratings (0.25W), and thermal characteristics. The substitute parts feature improved tolerance specifications, which represent performance enhancements rather than compatibility issues.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG3216V-6491-P-T1 offers ±0.02% tolerance, RG3216V-6491-W-T1 offers ±0.05% tolerance, and RG3216V-6491-B-T5 offers ±0.1% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance, matching the specifications of the original part.

Q: What packaging formats are available for the substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The original RG3216V-6491-C-T5 was supplied in bulk packaging.

Q: Do the substitute parts have the same temperature coefficient?

A: Yes. All substitute parts maintain the ±5ppm/°C temperature coefficient and -55°C ~ 155°C operating temperature range of the original part.

Q: Why is the original part listed as obsolete?

A: The RG3216V-6491-C-T5 is obsolete, but the substitute parts (RG3216V-6491-P-T1, RG3216V-6491-B-T5, RG3216V-6491-W-T1) are active products with current manufacturing status, ensuring continued availability and supply chain support.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably within the same design. However, design specifications should account for the tolerance of the selected part.
