Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following electrical and mechanical parameters: resistance value (127 Ohms), package size (0805), composition (Thin Film), power rating, operating temperature range, and automotive qualification (AEC-Q200). The substitutes are categorized into two groups:

Upgrade Substitutes: Eight Susumu parts from the same RG series offering improved tolerance specifications (±0.02%, ±0.05%, ±0.1%) and enhanced temperature coefficients (±5ppm/°C, ±10ppm/°C, ±25ppm/°C) while maintaining identical resistance, power rating, package size, and AEC-Q200 qualification.

Direct Substitutes: Two parts from alternative manufacturers (TE Connectivity and YAGEO) matching the key electrical parameters. The 3-2176091-4 provides higher power rating (0.25W) with ±0.1% tolerance. The RT0805CRD07127RL maintains identical ±0.25% tolerance and ±25ppm/°C temperature coefficient.

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: The eight Susumu RG series parts (RG2012N-1270-B-T5, RG2012N-1270-W-T1, RG2012P-1270-B-T5, RG2012P-1270-W-T5, RG2012V-1270-B-T5, RG2012V-1270-P-T1, RG2012V-1270-W-T1, RG2012V-1270-W-T5) maintain the Anti-Sulfur and Automotive AEC-Q200 qualification required for automotive environments. All eight parts are Active status and ROHS3 Compliant.

For Direct Tolerance Match: The RT0805CRD07127RL from YAGEO provides identical ±0.25% tolerance and ±25ppm/°C temperature coefficient as the original part. This part is Active status, ROHS3 Compliant, and suitable for non-automotive applications where AEC-Q200 qualification is not required.

For Enhanced Stability: The RG2012V series parts (RG2012V-1270-B-T5, RG2012V-1270-P-T1, RG2012V-1270-W-T1, RG2012V-1270-W-T5) offer ±5ppm/°C temperature coefficient, providing improved performance in temperature-sensitive circuits while maintaining AEC-Q200 qualification.

For Higher Power Rating: The 3-2176091-4 from TE Connectivity provides 0.25W power rating with ±0.1% tolerance, suitable for applications requiring higher power dissipation. This part is Active status and ROHS3 Compliant but does not include AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting RG2012P-1270-C-T5?
A: Resistance value (127 Ohms), tolerance, power rating (0.125W minimum), package size (0805), temperature coefficient, and operating temperature range (-55°C ~ 155°C) must be considered. For automotive applications, AEC-Q200 qualification and Anti-Sulfur features are required.

Q: Can I use a substitute with tighter tolerance than ±0.25%?
A: Tighter tolerance specifications (±0.02%, ±0.05%, ±0.1%) provide equal or better performance and are compatible substitutes for the ±0.25% original part.

Q: Are all substitute parts mechanically compatible?
A: All listed substitutes use 0805 (2012 Metric) package with 0.079" L x 0.049" W (2.00mm x 1.25mm) dimensions and 2 terminations, ensuring mechanical compatibility. The 3-2176091-4 has 0.026" height versus 0.020" for other parts.

Q: Which substitutes maintain AEC-Q200 qualification?
A: The eight Susumu RG series parts (RG2012N-1270-B-T5, RG2012N-1270-W-T1, RG2012P-1270-B-T5, RG2012P-1270-W-T5, RG2012V-1270-B-T5, RG2012V-1270-P-T1, RG2012V-1270-W-T1, RG2012V-1270-W-T5) carry AEC-Q200 ratings. The 3-2176091-4 and RT0805CRD07127RL do not include this qualification.

Q: What is the difference between temperature coefficients?
A: The original part has ±25ppm/°C. Substitutes offer ±5ppm/°C (RG2012V series), ±10ppm/°C (RG2012N series), or ±25ppm/°C (RG2012P series, 3-2176091-4, RT0805CRD07127RL). Lower temperature coefficient values indicate better resistance stability across temperature variations.

Q: Are all parts RoHS compliant?
A: All listed parts are ROHS3 Compliant and carry Moisture Sensitivity Level (MSL) 1 (Unlimited) rating.
