Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-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: 0805 (2012 Metric) (physical and electrical compatibility)
• Power rating: 0.125W (1/8W) (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 rating: AEC-Q200 (qualification standard)
• Anti-sulfur construction (reliability feature)

Allowable Variation Parameter:

• Tolerance: Substitute parts with equal or tighter (lower) tolerance values are acceptable. The main part specifies ±0.25%; substitutes with ±0.1%, ±0.05%, or ±0.02% tolerance are electrically and mechanically compatible.

All substitute parts listed maintain identical electrical performance in the resistance value, power dissipation, and thermal characteristics while offering improved tolerance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All four substitute parts are direct functional equivalents to the RG2012V-6491-C-T5 and are suitable for replacement in applications where the original part is no longer available. Selection among the substitutes is based on tolerance requirements and product availability:

RG2012V-6491-B-T5 (±0.1% Tolerance)

• Recommended for applications requiring improved tolerance performance over the original ±0.25% specification
• Active product status ensures long-term availability
• Inventory: 1031 Pcs

RG2012V-6491-P-T1 (±0.02% Tolerance)

• Recommended for precision applications requiring the tightest tolerance specification
• Highest accuracy thin film resistor among available substitutes
• Active product status with established supply chain
• Inventory: 740 Pcs

RG2012V-6491-W-T1 (±0.05% Tolerance)

• Recommended for applications requiring moderate tolerance improvement with standard tape & reel packaging
• Active product status
• Inventory: 759 Pcs

RG2012V-6491-W-T5 (±0.05% Tolerance)

• Recommended for applications requiring moderate tolerance improvement
• Highest inventory availability among substitutes
• Active product status
• Inventory: 991 Pcs

All substitutes maintain identical electrical performance, thermal characteristics, automotive qualification, and compliance certifications. Selection should be based on specific tolerance requirements of the application circuit and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-6491-B-T5, RG2012V-6491-P-T1, RG2012V-6491-W-T1, and RG2012V-6491-W-T5 be used interchangeably with RG2012V-6491-C-T5?

A: Yes. All substitute parts are electrically and mechanically compatible. They share identical resistance values (6.49 kOhms), power ratings (0.125W), package dimensions (0805), thermal coefficients (±5ppm/°C), operating temperature ranges (-55°C ~ 155°C), and automotive qualifications (AEC-Q200). The substitutes offer equal or improved tolerance specifications.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-6491-B-T5 offers ±0.1% tolerance, RG2012V-6491-W-T1 and RG2012V-6491-W-T5 offer ±0.05% tolerance, and RG2012V-6491-P-T1 offers ±0.02% tolerance. All other electrical and mechanical parameters are identical.

Q: Why are the substitute parts listed as "Active" while the original is "Obsolete"?

A: The RG2012V-6491-C-T5 has been discontinued by the manufacturer. The substitute parts represent the current active alternatives in the Susumu RG series that maintain the same electrical specifications and package format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the original part.

Q: Can I use a substitute part with tighter tolerance in place of the original?

A: Yes. Tighter tolerance specifications are fully compatible and represent an upgrade in performance. A component with ±0.1%, ±0.05%, or ±0.02% tolerance will perform identically to or better than the original ±0.25% specification in any circuit application.

Q: What is the moisture sensitivity level for all parts?

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

Q: Are the substitute parts suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, making them suitable for automotive and harsh environment applications.
