Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-242-W-T1 is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Resistance value: 2.4 kOhms
• Tolerance: ±0.05% (or tighter)
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200

Substitution Categories:

Direct Equivalents (Packaging Variant): Parts with identical electrical specifications but different packaging formats (Tape & Reel vs. Cut Tape). These maintain full functional compatibility.

Upgraded Equivalents (Enhanced Performance): Parts with tighter tolerance (±0.02%), lower temperature coefficient (±5ppm/°C or ±10ppm/°C), or improved specifications while maintaining all critical electrical parameters. These provide superior performance in the same footprint.

Similar Parts (Relaxed Tolerance): Parts with identical resistance, power rating, and package but with ±0.1% tolerance instead of ±0.05%. These are suitable only when tolerance relaxation is acceptable for the application.

Cross-Manufacturer Equivalents: Parts from alternative manufacturers (Panasonic, YAGEO) meeting identical electrical and mechanical specifications with AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent: RG2012P-242-W-T5 (Susumu) is the direct functional equivalent of RG2012P-242-W-T1, differing only in packaging format (Tape & Reel vs. Bulk). This part maintains identical electrical specifications and is currently in active production status with full AEC-Q200 automotive qualification.

Secondary Recommendations - Enhanced Performance Equivalents: RG2012N-242-W-T5 and RG2012V-242-W-T1/T5 (Susumu) provide improved temperature coefficient performance (±10ppm/°C and ±5ppm/°C respectively) while maintaining all critical electrical parameters. These parts are suitable for applications requiring superior thermal stability and are in active production.

RG2012V-242-P-T1 (Susumu) offers the tightest tolerance specification (±0.02%) with the lowest temperature coefficient (±5ppm/°C), providing maximum precision for demanding measurement and calibration circuits.

Cross-Manufacturer Alternatives: ERA-6ARW242V (Panasonic) provides equivalent electrical specifications with AEC-Q200 qualification and is available in high volume. This part is suitable for applications where multi-source qualification is required.

RT0805WRB072K4L (YAGEO) meets electrical specifications but lacks explicit AEC-Q200 automotive qualification in the provided data. Selection of this part requires verification of automotive compliance requirements for the specific application.

Tolerance Relaxation Option: RG2012P-242-B-T5 (Susumu) is suitable only when application requirements permit tolerance relaxation to ±0.1%. This part offers the highest inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-242-W-T5 be used as a direct replacement for RG2012P-242-W-T1?

A: Yes. RG2012P-242-W-T5 is electrically and mechanically identical to RG2012P-242-W-T1. The difference is packaging format: T1 denotes bulk packaging while T5 denotes Tape & Reel format. Both parts have identical electrical performance and AEC-Q200 qualification.

Q: What is the difference between RG2012N and RG2012V series?

A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C while RG2012V series has ±5ppm/°C. Both maintain the same 2.4 kOhms resistance, ±0.05% tolerance, and 0805 package. RG2012V provides superior thermal stability for precision applications.

Q: Can I use RG2012P-242-B-T5 (±0.1% tolerance) instead of the original ±0.05% part?

A: RG2012P-242-B-T5 is suitable only if your circuit design tolerates the relaxed ±0.1% tolerance specification. The original RG2012P-242-W-T1 specifies ±0.05% tolerance. Verify tolerance requirements in your application before substitution.

Q: What does the packaging designation (T1, T5, CT) mean?

A: T1 indicates bulk packaging, T5 indicates Tape & Reel format, and CT indicates Cut Tape & Digi-Reel format. These designations affect procurement and assembly processes but do not change electrical or mechanical specifications of the component itself.

Q: Is ERA-6ARW242V (Panasonic) fully compatible with the Susumu RG2012P-242-W-T1?

A: ERA-6ARW242V is electrically compatible with identical resistance, tolerance, power rating, and package specifications. Both parts carry AEC-Q200 automotive qualification. The maximum seated height differs slightly (0.024" vs. 0.020"), which is within typical PCB design tolerances for 0805 components.

Q: Why does RT0805WRB072K4L lack AEC-Q200 qualification in the data provided?

A: The provided data does not list AEC-Q200 qualification for the YAGEO RT0805WRB072K4L. Verification of automotive compliance requirements is necessary before selecting this part for automotive applications.

Q: Which substitute part offers the best temperature stability?

A: RG2012V-242-P-T1 and RG2012V-242-W-T1/T5 offer the lowest temperature coefficient at ±5ppm/°C, providing superior thermal stability compared to the original ±25ppm/°C specification. These parts are recommended for precision analog circuits and measurement applications.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all selected parts meet the minimum electrical specifications required by your circuit. However, maintaining consistency with a single part number throughout production is recommended for supply chain management and quality control.
