Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-6491-W-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 6.49 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory compliance)

Allowable Variation Parameters:

• Tolerance: ±0.05% or tighter (lower tolerance values are acceptable upgrades)
• Temperature coefficient: ±25ppm/°C or lower (lower values indicate improved stability)
• Packaging format: Tape & Reel (TR) acceptable as alternative to standard packaging
• Manufacturer: Susumu or equivalent qualified manufacturers

Substitute parts are grouped into two categories: direct equivalents from Susumu RG series with identical or improved specifications, and similar parts from alternative manufacturers meeting the same electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Susumu RG Series Substitutes (Recommended Primary Options):

The RG2012P-6491-W-T1 can be directly replaced with active Susumu RG series parts maintaining identical electrical specifications. RG2012P-6491-W-T5 provides the same tolerance and temperature coefficient with Tape & Reel packaging and active product status. RG2012N-6491-W-T1 and RG2012V-6491-W-T1 offer improved temperature coefficient performance (±10ppm/°C and ±5ppm/°C respectively) while maintaining ±0.05% tolerance, providing enhanced thermal stability. RG2012V-6491-P-T1 delivers the tightest tolerance specification (±0.02%) with superior temperature coefficient (±5ppm/°C) for applications requiring maximum precision.

All Susumu RG series substitutes maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical package dimensions. Selection between these options depends on application requirements for tolerance and temperature stability.

Alternative Manufacturer Option:

ERA-6AEB6491V from Panasonic Electronic Components provides electrical compatibility with identical resistance, power rating, and package specifications. This part carries AEC-Q200 qualification and ROHS3 compliance. The tolerance specification is ±0.1%, which is wider than the original ±0.05%, and temperature coefficient is ±25ppm/°C. This part is suitable for applications where tolerance relaxation is acceptable and alternative manufacturer sourcing is required.

Product Status Consideration:

The original RG2012P-6491-W-T1 is obsolete. All recommended substitutes carry active product status, ensuring continued availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-6491-W-T1 replace RG2012P-6491-W-T1 in my design?

A: Yes. RG2012V-6491-W-T1 is electrically and mechanically compatible. Both parts share identical resistance (6.49 kOhms), tolerance (±0.05%), power rating (0.125W), and 0805 package. RG2012V-6491-W-T1 offers improved temperature coefficient (±5ppm/°C versus ±25ppm/°C), providing superior thermal stability. The primary difference is packaging format (Tape & Reel versus standard) and active product status.

Q: What is the difference between RG2012N-6491-W-T1 and RG2012V-6491-W-T1?

A: Both parts are electrically compatible with the original RG2012P-6491-W-T1. The key difference is temperature coefficient: RG2012N-6491-W-T1 has ±10ppm/°C while RG2012V-6491-W-T1 has ±5ppm/°C. RG2012V-6491-W-T1 provides superior temperature stability. Both maintain ±0.05% tolerance and 0.125W power rating in 0805 package.

Q: Is ERA-6AEB6491V from Panasonic a suitable substitute?

A: ERA-6AEB6491V is mechanically and electrically compatible for the core specifications: 6.49 kOhms resistance, 0.125W power rating, 0805 package, and AEC-Q200 qualification. However, tolerance is ±0.1% compared to the original ±0.05%, representing a wider tolerance band. This part is suitable when alternative manufacturer sourcing is required and tolerance relaxation is acceptable for the application.

Q: What does the "T1" and "T5" designation mean in the part number?

A: The suffix designates packaging format. T1 indicates standard packaging, while T5 indicates Tape & Reel (TR) format. Both formats contain identical components; the difference is in delivery and handling configuration. Tape & Reel format is standard for high-volume manufacturing and automated assembly.

Q: Are all substitute parts ROHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitute parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, matching the original RG2012P-6491-W-T1 specifications. This ensures regulatory compliance and automotive reliability standards are preserved across all substitutes.

Q: Can I use RG2012V-6491-P-T1 if my application requires ±0.05% tolerance?

A: Yes. RG2012V-6491-P-T1 has ±0.02% tolerance, which is tighter than the required ±0.05%. Tighter tolerance specifications are acceptable substitutes for applications requiring ±0.05% or looser tolerance. This part provides enhanced precision with superior temperature coefficient (±5ppm/°C).

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts maintain the identical operating temperature range of -55°C to 155°C, matching the original RG2012P-6491-W-T1 specification.
