Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Same Manufacturer):

The Susumu RG series provides direct upgrades with improved specifications while maintaining identical package geometry and thermal characteristics. RG2012P-1910-B-T5 and RG2012P-1910-W-T5 offer tighter tolerance specifications (±0.1% and ±0.05% respectively) with identical temperature coefficient (±25ppm/°C) and active product status. These are recommended for applications requiring enhanced precision without thermal performance changes.

RG2012N and RG2012V series variants provide superior temperature stability with reduced temperature coefficients (±10ppm/°C and ±5ppm/°C respectively). RG2012V-1910-P-T1 delivers the tightest tolerance specification (±0.02%) combined with the lowest temperature coefficient (±5ppm/°C), suitable for precision analog circuits and measurement applications.

Secondary Substitutes (Cross-Manufacturer Alternatives):

RT0805CRD07191RL (YAGEO) provides electrical and mechanical equivalence with identical tolerance (±0.25%), power rating (0.125W), and temperature coefficient (±25ppm/°C). This part maintains full compatibility with the original specification and is suitable for direct replacement in non-critical applications.

5-2176091-1 (TE Connectivity) offers increased power rating (0.25W versus 0.125W) with improved tolerance (±0.1%) and identical temperature coefficient (±25ppm/°C). This part is applicable in applications where thermal margin enhancement is beneficial, though the increased package height (0.65mm versus 0.50mm) requires verification of PCB layout clearance.

Compliance Considerations:

All Susumu RG series substitutes maintain AEC-Q200 automotive qualification and anti-sulfur coating. YAGEO RT0805CRD07191RL provides ROHS3 compliance without automotive certification. TE Connectivity 5-2176091-1 provides ROHS3 compliance with undefined REACH status. Selection should align with application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-1910-B-T5 directly replace RG2012P-1910-C-T5?

A: Yes. RG2012P-1910-B-T5 is a direct substitute with improved tolerance specification (±0.1% versus ±0.25%). Both parts share identical resistance value (191 Ohms), power rating (0.125W), package format (0805), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The tighter tolerance provides enhanced precision without performance degradation.

Q: What is the difference between RG2012P, RG2012N, and RG2012V series?

A: The primary difference is temperature coefficient specification. RG2012P series maintains ±25ppm/°C, RG2012N series provides ±10ppm/°C, and RG2012V series delivers ±5ppm/°C. All three series share identical resistance, power rating, package format, and operating temperature range. Selection depends on thermal stability requirements of the application.

Q: Is TE Connectivity 5-2176091-1 compatible with the original part?

A: 5-2176091-1 is mechanically and electrically compatible with identical resistance (191 Ohms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and operating temperature range. The increased power rating (0.25W versus 0.125W) and package height (0.65mm versus 0.50mm) require verification of PCB layout clearance and thermal design margins.

Q: Can YAGEO RT0805CRD07191RL be used in automotive applications?

A: RT0805CRD07191RL provides ROHS3 compliance and identical electrical specifications to the original part. However, it lacks AEC-Q200 automotive certification. Use in automotive applications requires design review and customer approval if AEC-Q200 qualification is a contractual or regulatory requirement.

Q: What tolerance specification should be selected for precision analog circuits?

A: RG2012V-1910-P-T1 provides the tightest tolerance (±0.02%) combined with the lowest temperature coefficient (±5ppm/°C), making it optimal for precision analog applications. RG2012V-1910-W-T1 and RG2012V-1910-W-T5 offer ±0.05% tolerance with ±5ppm/°C temperature coefficient as alternative precision options.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. Susumu RG series parts maintain full AEC-Q200 automotive qualification. YAGEO RT0805CRD07191RL and TE Connectivity 5-2176091-1 provide ROHS3 compliance; however, TE Connectivity REACH status is listed as vendor undefined.

Q: What is the impact of selecting a higher power-rated part?

A: TE Connectivity 5-2176091-1 provides 0.25W (1/4W) rating versus the original 0.125W (1/8W). Higher power rating increases thermal margin and component robustness. The increased package height (0.65mm versus 0.50mm) requires PCB layout verification to ensure clearance with adjacent components and solder joint integrity.
