Package type: 0805 (2012 Metric) (exact match required)
Operating temperature range: -55°C to 155°C (minimum requirement)
Composition: Thin Film (required for performance characteristics)

Allowable Variation Parameters:

Tolerance: Can be equal or tighter (±0.1% or better)
Power rating: Can be equal or higher (0.125W or greater)
Temperature coefficient: Can be equal or lower in absolute value (±25ppm/°C or better)

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications, Active Status):

RG2012P-1650-B-T5 is the primary direct equivalent. It maintains identical electrical specifications (165 Ω, ±0.1%, 0.125W, ±25ppm/°C) and automotive AEC-Q200 qualification. The only difference is packaging format (Tape & Reel versus bulk), which does not affect electrical performance. This part is active and recommended for direct replacement in production environments.

ERA-6AEB1650V from Panasonic is an alternative direct equivalent with identical electrical specifications and AEC-Q200 qualification. It provides supply diversification from a different manufacturer while maintaining full compatibility.

Upgraded Alternatives (Enhanced Specifications):

RG2012N-1650-B-T5 offers improved temperature coefficient (±10ppm/°C versus ±25ppm/°C) while maintaining all other specifications. This upgrade is suitable for applications requiring better temperature stability.

RG2012V-1650-B-T5 provides the best temperature coefficient performance (±5ppm/°C) within the ±0.1% tolerance class, enabling superior long-term stability in temperature-sensitive circuits.

RG2012N-1650-W-T1 and RG2012P-1650-W-T5 offer tighter tolerance (±0.05%) for precision applications requiring reduced resistance variation.

RG2012V-1650-P-T1 provides the tightest tolerance specification (±0.02%) combined with the lowest temperature coefficient (±5ppm/°C), representing the highest precision option within the 0805 package format.

Alternative with Higher Power Rating:

4-2176091-5 from TE Connectivity provides double the power rating (0.25W versus 0.125W) in the same 0805 package. This part is suitable for applications requiring increased power dissipation capability. Note: This part does not carry AEC-Q200 automotive qualification and is RoHS non-compliant, limiting its use to non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-1650-B-T5 be used as a direct replacement for RG2012P-1650-B-T1?

A: Yes. RG2012P-1650-B-T5 is a direct functional equivalent with identical electrical specifications (165 Ω, ±0.1%, 0.125W, ±25ppm/°C) and AEC-Q200 automotive qualification. The difference in packaging format (Tape & Reel versus bulk) does not affect electrical performance or circuit compatibility.

Q: What is the difference between Susumu RG series variants (P, N, V)?

A: The letter designation indicates temperature coefficient performance. RG2012P series has ±25ppm/°C, RG2012N series has ±10ppm/°C, and RG2012V series has ±5ppm/°C. All maintain the same 165 Ω resistance and 0.125W power rating when specified with identical tolerance codes.

Q: Can I use RG2012V-1650-P-T1 in place of RG2012P-1650-B-T1?

A: Yes. RG2012V-1650-P-T1 is a compatible upgrade with tighter tolerance (±0.02% versus ±0.1%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). The enhanced specifications ensure full backward compatibility while providing improved performance characteristics.

Q: Is 4-2176091-5 suitable for automotive applications?

A: No. While 4-2176091-5 maintains the same 165 Ω resistance and ±0.1% tolerance, it lacks AEC-Q200 automotive qualification and is RoHS non-compliant. This part is restricted to non-automotive applications. For automotive use, select from Susumu RG series or Panasonic ERA-6AEB1650V.

Q: What is the significance of the packaging designation (T1 versus T5)?

A: T1 and T5 designations refer to tape reel specifications and packaging formats. Both are functionally equivalent in terms of electrical performance. Selection depends on manufacturing process requirements and supply chain logistics rather than circuit functionality.

Q: Can I substitute ERA-6AEB1650V for the obsolete RG2012P-1650-B-T1?

A: Yes. ERA-6AEB1650V from Panasonic provides identical electrical specifications (165 Ω, ±0.1%, 0.125W, ±25ppm/°C) and AEC-Q200 automotive qualification. This substitution enables supply continuity from an alternative manufacturer while maintaining full circuit compatibility.

Q: Why would I choose a higher tolerance part like RG2012N-1650-W-T1 (±0.05%) over the original specification (±0.1%)?

A: Tighter tolerance specifications reduce resistance variation across the production batch, improving circuit accuracy and performance consistency. Applications requiring precision analog circuits, reference networks, or measurement instrumentation benefit from tighter tolerance parts. The trade-off is typically higher component cost.

Q: Are all substitute parts ROHS3 compliant?

A: No. Most Susumu RG series and Panasonic ERA-6AEB1650V parts are ROHS3 compliant. However, 4-2176091-5 from TE Connectivity is RoHS non-compliant. Verify compliance requirements for your specific application before selection.
