Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-6490-C-T5 is determined by the following critical parameters that must remain constant across all alternatives:

Fixed Parameters (Non-Negotiable):

• Resistance value: 649 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur coating
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Tolerance: The main part specifies ±0.25%. Substitute parts with tighter (lower) tolerance values are electrically and mechanically compatible, as they represent improved precision grades of the same resistor family.

All four substitute parts maintain identical electrical and mechanical specifications except for tolerance ratings, which range from ±0.1% to ±0.02%, representing precision upgrades suitable for applications requiring higher accuracy.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All four substitute parts are direct functional equivalents of the RG2012V-6490-C-T5 and are suitable for replacement in applications where the original part is no longer available. Selection among the substitutes depends on application tolerance requirements:

RG2012V-6490-W-T5 (±0.05% tolerance, 879 Pcs in stock): Recommended for general automotive applications requiring improved accuracy over the original ±0.25% specification. This part offers the highest inventory availability and represents a balanced upgrade in precision.

RG2012V-6490-W-T1 (±0.05% tolerance, 696 Pcs in stock): Functionally equivalent to RG2012V-6490-W-T5 with identical tolerance specification. Selection between these two variants depends on tape reel configuration requirements specific to assembly processes.

RG2012V-6490-B-T5 (±0.1% tolerance, 682 Pcs in stock): Suitable for applications requiring moderate precision improvement. Offers tighter tolerance than the original part while maintaining cost efficiency.

RG2012V-6490-P-T1 (±0.02% tolerance, 677 Pcs in stock): Specified for precision-critical automotive circuits requiring the highest accuracy grade. This part represents the maximum tolerance specification available within the RG2012V-6490 series.

All substitute parts maintain identical AEC-Q200 automotive qualification, anti-sulfur coating, RoHS3 compliance, and unlimited moisture sensitivity rating. Mechanical and thermal characteristics remain unchanged across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-6490-C-T5 be directly replaced with any of the substitute parts?

A: Yes. All four substitute parts are direct replacements. They maintain identical resistance value (649 Ohms), package size (0805), power rating (0.125W), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The only difference is tolerance specification, which is tighter (more precise) in all substitutes.

Q: What does tolerance mean in the context of these resistors?

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 649 Ohm specification. The original part allows ±0.25% deviation (approximately ±1.62 Ohms). Substitute parts offer tighter tolerances: ±0.1% (±0.649 Ohms), ±0.05% (±0.325 Ohms), and ±0.02% (±0.130 Ohms). Tighter tolerance means higher precision and more predictable circuit behavior.

Q: Are there any mechanical differences between the main part and substitutes?

A: No. All parts share identical mechanical specifications: 0805 (2012 Metric) package, 0.079" length × 0.049" width (2.00mm × 1.25mm), maximum seated height of 0.020" (0.50mm), and two terminations. They are mechanically interchangeable on PCBs designed for the original part.

Q: Why is the original part classified as obsolete?

A: The RG2012V-6490-C-T5 is no longer in active production. However, four active alternatives from the same RG series with identical core specifications are available as direct replacements.

Q: Do all substitute parts carry the same automotive certifications?

A: Yes. All substitute parts maintain AEC-Q200 qualification, anti-sulfur coating, RoHS3 compliance, and MSL rating of 1 (Unlimited). They are fully qualified for automotive applications.

Q: What is the difference between RG2012V-6490-W-T1 and RG2012V-6490-W-T5?

A: Both parts have identical electrical specifications (649 Ohms ±0.05% tolerance). The difference is in packaging configuration: T1 and T5 designations refer to different tape reel specifications. Selection depends on assembly equipment compatibility and tape reel format requirements.

Q: Which substitute should I select for a new design?

A: For new designs, RG2012V-6490-W-T5 is recommended due to highest inventory availability (879 Pcs), active product status, and ±0.05% tolerance that provides precision improvement over the original specification while maintaining cost efficiency. For precision-critical applications, RG2012V-6490-P-T1 offers the tightest tolerance (±0.02%).

Q: Are all parts RoHS3 compliant?

A: Yes. The main part and all four substitutes are ROHS3 compliant, meeting environmental and regulatory requirements for electronic components.
