Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1911-C-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 1.91 kOhms
Package type: 0805 (2012 Metric)
Power rating: 0.125W (1/8W) minimum
Operating temperature range: -55°C to 155°C minimum
Composition: Thin Film

Allowable Variations:

Tolerance: May be equal to or tighter (lower) than ±0.25%
Temperature coefficient: May be equal to or lower than ±25ppm/°C
Packaging format: Tape & Reel (TR) acceptable as functional equivalent to bulk packaging
Automotive qualification: AEC-Q200 maintained across all active substitutes

Upgrade vs. Direct Substitutes:

Upgrade substitutes from Susumu (RG series) provide tighter tolerance specifications (±0.1%, ±0.05%, ±0.02%) and improved temperature stability (±10ppm/°C, ±5ppm/°C) while maintaining identical resistance, package, power rating, and operating temperature range. These components are active products with higher inventory availability.

Direct substitutes from alternative manufacturers (TE Connectivity, YAGEO) maintain the same tolerance and electrical characteristics but may differ in packaging height, series designation, or feature set. The TE Connectivity 4-2176092-2 offers increased power rating (0.25W) while maintaining all other critical parameters.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The RT0805CRD071K91L from YAGEO provides electrical and mechanical equivalence to the RG2012P-1911-C-T5, matching tolerance (±0.25%), power rating (0.125W), temperature coefficient (±25ppm/°C), and package dimensions. This part is active and available in production quantities. Note that YAGEO RT series components do not carry AEC-Q200 automotive qualification.

For Automotive Applications Requiring AEC-Q200:

The RG2012P-1911-B-T5 from Susumu is the recommended direct substitute for automotive designs. This part maintains AEC-Q200 qualification, identical package and power rating, and improves tolerance to ±0.1% while retaining the same temperature coefficient (±25ppm/°C) as the original. This part is active with 6180 units in stock.

For Enhanced Precision Requirements:

When circuit design permits tighter tolerance specifications, the RG2012V series (RG2012V-1911-B-T5, RG2012V-1911-W-T1, RG2012V-1911-W-T5, RG2012V-1911-P-T1) offers superior temperature stability with temperature coefficients as low as ±5ppm/°C and tolerance values down to ±0.02%. All variants maintain AEC-Q200 qualification and 0805 package compatibility.

For Increased Power Dissipation:

The TE Connectivity 4-2176092-2 provides double the power rating (0.25W vs. 0.125W) in the same 0805 package footprint. This part is suitable for applications requiring higher thermal margin. However, this component does not carry AEC-Q200 certification and should be evaluated for non-automotive applications or where automotive qualification is not mandated.

Product Status Consideration:

All recommended substitutes are active products with current manufacturing support. The original RG2012P-1911-C-T5 is obsolete; transition to an active equivalent is necessary for new designs and long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-1911-C-T5 be replaced with any 1.91 kOhm 0805 resistor?

A: No. Substitution requires matching the 0.125W power rating, -55°C to 155°C operating temperature range, and thin film composition. For automotive applications, AEC-Q200 qualification is mandatory. Tolerance and temperature coefficient may be equal to or better than the original specification.

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 identical resistance, package, and power rating. The V series offers the best temperature stability for precision applications.

Q: Is the TE Connectivity 4-2176092-2 a suitable replacement for automotive use?

A: The 4-2176092-2 is electrically compatible (1.91 kΩ, ±0.1%, 0805 package) but does not carry AEC-Q200 automotive qualification. It is suitable for non-automotive applications or where automotive certification is not required. For automotive designs, use Susumu RG series parts with AEC-Q200 rating.

Q: Why does the YAGEO RT0805CRD071K91L lack AEC-Q200 certification?

A: YAGEO RT series components are commercial-grade thin film resistors. They meet the same electrical specifications as the original part but are not qualified to automotive reliability standards. Use this part only in non-automotive applications or where automotive qualification is not a design requirement.

Q: Can I use RG2012V-1911-P-T1 (±0.02% tolerance) as a drop-in replacement?

A: Yes. The RG2012V-1911-P-T1 is mechanically and electrically compatible with the RG2012P-1911-C-T5. The tighter tolerance (±0.02% vs. ±0.25%) and improved temperature coefficient (±5ppm/°C vs. ±25ppm/°C) provide enhanced performance. No circuit modifications are required.

Q: What is the difference between Tape & Reel (TR) and bulk packaging?

A: Tape & Reel packaging is the standard format for automated assembly processes. All listed substitute parts are available in Tape & Reel format, which is functionally equivalent to the original part's packaging for component selection purposes. Packaging format does not affect electrical performance.

Q: Does the increased power rating of the 4-2176092-2 (0.25W vs. 0.125W) affect circuit operation?

A: No. A higher power rating does not change electrical behavior. The 4-2176092-2 will operate identically to the original part in circuits designed for 0.125W dissipation. The higher rating provides additional thermal margin and reliability headroom in applications with variable power conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original RG2012P-1911-C-T5 is also ROHS3 compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) across all parts, indicating no special storage or handling requirements.

Q: Which substitute offers the best long-term availability?

A: The Susumu RG2012P-1911-B-T5 is recommended for long-term supply security. It is an active product with 6180 units in current inventory, carries AEC-Q200 automotive qualification, and is part of Susumu's established RG series production line. This part provides the most direct replacement path from the obsolete RG2012P-1911-C-T5.
