Substitute Part Grouping Explanation

Substitute parts are categorized into two groups based on electrical and mechanical compatibility:

Upgrade Substitutes maintain identical resistance (243 Ohms), package (0805), power rating (0.125W or higher), operating temperature range (-55°C ~ 155°C), composition (Thin Film), and AEC-Q200 automotive qualification. These parts offer improved tolerance (±0.1%, ±0.05%, ±0.02%) and/or superior temperature coefficient (±10ppm/°C, ±5ppm/°C) compared to the original ±0.25% and ±25ppm/°C specifications.

Direct Substitutes match core electrical parameters including resistance (243 Ohms), package (0805), and composition (Thin Film), with equivalent or improved tolerance (±0.25%, ±0.1%) and temperature coefficient (±25ppm/°C). The 6-2176091-0 provides higher power rating (0.25W) while RT0805CRD07243RL maintains identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C).

Key parameters determining substitutability: Resistance value, tolerance, power rating, package size, temperature coefficient, operating temperature range, composition type, and AEC-Q200 qualification for automotive applications.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification and Anti-Sulfur features, the Susumu RG series upgrade substitutes (RG2012N-2430-B-T5, RG2012P-2430-B-T5, RG2012P-2430-W-T5, RG2012V-2430-B-T5, RG2012V-2430-P-T1, RG2012V-2430-W-T1, RG2012V-2430-W-T5, RG2012N-2430-W-T1) maintain identical package dimensions, operating temperature range, and automotive qualification status while providing improved tolerance and temperature coefficient performance. All listed parts carry Active product status and ROHS3 Compliant certification.

The 6-2176091-0 from TE Connectivity and RT0805CRD07243RL from YAGEO offer Active product status with ROHS3 compliance but do not include AEC-Q200 ratings or Anti-Sulfur features. The 6-2176091-0 provides higher power rating (0.25W) with slightly increased height (0.65mm vs 0.50mm). The RT0805CRD07243RL matches the original tolerance specification (±0.25%) and temperature coefficient (±25ppm/°C).

Frequently Asked Questions (FAQ)

What parameters must match for direct substitution?
Resistance value (243 Ohms), package size (0805), power rating (≥0.125W), and operating temperature range (-55°C ~ 155°C) must match. For automotive applications, AEC-Q200 qualification is required.

Can parts with tighter tolerance replace ±0.25% tolerance parts?
Parts with ±0.1%, ±0.05%, or ±0.02% tolerance provide equivalent or superior resistance accuracy compared to ±0.25% specifications.

Are there package dimension differences among substitutes?
All substitutes maintain 0805 (2012 Metric) package with 2.00mm x 1.25mm dimensions. Height varies from 0.50mm (Susumu RG series) to 0.65mm (6-2176091-0) to 0.60mm (RT0805CRD07243RL).

Which substitutes maintain AEC-Q200 automotive qualification?
The Susumu RG2012N, RG2012P, and RG2012V series parts carry AEC-Q200 ratings and Anti-Sulfur features. The 6-2176091-0 and RT0805CRD07243RL do not include AEC-Q200 qualification.

How does temperature coefficient affect substitution compatibility?
Parts with ±10ppm/°C or ±5ppm/°C temperature coefficients provide improved stability compared to the original ±25ppm/°C specification across the -55°C ~ 155°C operating range.
