Substitute Part Grouping Explanation

Substitution of the RG2012P-2800-B-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Resistance value: 280 Ohms (exact match required)
Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
Power rating: 0.125W minimum (1/8W or higher acceptable)
Composition: Thin Film (electrical performance characteristics)
Operating temperature range: -55°C ~ 155°C minimum (environmental suitability)

Acceptable Variation Parameters:

Tolerance: ±0.1% or tighter (±0.05%, ±0.02% acceptable as upgrades)
Temperature coefficient: ±25ppm/°C or lower (±10ppm/°C, ±5ppm/°C acceptable as upgrades)
Packaging format: Tape & Reel (TR) acceptable for manufacturing environments
Automotive qualification: AEC-Q200 maintained across all Susumu alternatives

Non-Substitutable Parameters:

Resistance value deviation
Package size reduction below 0805
Power rating below 0.125W
Operating temperature range narrower than specified

Substitute parts are grouped into two categories: direct equivalents (matching all primary specifications) and upgrades (improved tolerance or temperature coefficient performance while maintaining core functionality).

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-2800-B-T5 is the direct active equivalent to RG2012P-2800-B-T1. Both parts share identical electrical specifications (280 Ω, ±0.1% tolerance, 0.125W, ±25ppm/°C temperature coefficient) and maintain Susumu RG series continuity with AEC-Q200 automotive qualification. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard). This part is the recommended first choice for direct replacement.

Upgraded Alternatives (Improved Performance):

Susumu RG series upgrades offer enhanced performance characteristics while maintaining core compatibility:

RG2012V-2800-B-T5: Improves temperature coefficient to ±5ppm/°C while maintaining ±0.1% tolerance and 0.125W rating
RG2012N-2800-B-T5: Improves temperature coefficient to ±10ppm/°C while maintaining ±0.1% tolerance and 0.125W rating
RG2012V-2800-W-T1, RG2012V-2800-W-T5, RG2012N-2800-W-T1, RG2012P-2800-W-T5: Improve tolerance to ±0.05% with varying temperature coefficients

All Susumu alternatives maintain AEC-Q200 automotive qualification, ROHS3 compliance, and -55°C ~ 155°C operating temperature range.

Cross-Manufacturer Alternatives:

ERA-6AEB2800V (Panasonic): Provides functional equivalence with identical electrical specifications (280 Ω, ±0.1%, 0.125W, ±25ppm/°C). Maintains AEC-Q200 qualification and ROHS3 compliance. Highest inventory availability (10,925 units). Suitable for applications where manufacturer diversity is required.

6-2176091-6 (TE Connectivity): Provides electrical equivalence with increased power rating (0.25W vs. 0.125W). Maintains ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for applications requiring higher power dissipation margin. Note: This part lacks explicit AEC-Q200 certification in provided specifications.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2800-B-T5 be used as a direct replacement for RG2012P-2800-B-T1?

A: Yes. RG2012P-2800-B-T5 is the direct active equivalent. Both parts share identical resistance (280 Ω), tolerance (±0.1%), power rating (0.125W), temperature coefficient (±25ppm/°C), package (0805), and AEC-Q200 automotive qualification. The only difference is product status and packaging format.

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 resistance, tolerance, power rating, and package specifications. Selection depends on thermal stability requirements.

Q: Can I use RG2012V-2800-P-T1 (±0.02% tolerance) instead of RG2012P-2800-B-T1 (±0.1% tolerance)?

A: Yes. RG2012V-2800-P-T1 provides tighter tolerance (±0.02% vs. ±0.1%), which is a performance upgrade. All other critical parameters (280 Ω resistance, 0.125W power, 0805 package, -55°C ~ 155°C operating range, AEC-Q200 qualification) are maintained or improved.

Q: Is the TE Connectivity 6-2176091-6 suitable for my application?

A: 6-2176091-6 is electrically equivalent for resistance, tolerance, and temperature coefficient. However, it has a higher power rating (0.25W vs. 0.125W). This part is suitable if your circuit can accommodate the slightly larger physical dimensions (0.026" height vs. 0.020" maximum). Verify board layout compatibility before selection.

Q: Why does ERA-6AEB2800V have significantly higher inventory?

A: ERA-6AEB2800V is a Panasonic product with broader market distribution and higher production volume. It maintains identical electrical specifications and AEC-Q200 qualification to the original Susumu part, making it a viable alternative when Susumu inventory is constrained.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original RG2012P-2800-B-T1 specification.

Q: What is the significance of the T1 and T5 suffixes in Susumu part numbers?

A: The suffix indicates packaging format. T1 represents standard packaging, while T5 represents Tape & Reel (TR) format. Both formats contain identical components; the difference is in delivery and handling method for manufacturing environments.

Q: Can I substitute based on tolerance alone?

A: No. Tolerance is one of several critical parameters. Resistance value, power rating, package size, and operating temperature range must all match or exceed original specifications. Tolerance upgrades (tighter values) are acceptable only when all other parameters remain compatible.
