Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-111-W-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 110 Ohms (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Tolerance: ±0.05% or tighter (equal or better tolerance acceptable)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider range acceptable)

Secondary Compatibility Factors:

• Temperature coefficient: ±25ppm/°C or better (lower values indicate improved stability)
• Automotive qualification: AEC-Q200 preferred for automotive applications
• RoHS and REACH compliance: ROHS3 Compliant and REACH Unaffected (maintained across all substitutes)
• Moisture sensitivity: MSL 1 (Unlimited) maintained

Substitute parts are grouped into two categories: direct equivalents (identical specifications) and upgrades (enhanced performance characteristics such as improved temperature coefficient or tighter tolerance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-111-W-T5 is the direct equivalent to RG2012P-111-W-T1. Both parts share identical electrical specifications (110 Ohms ±0.05%, ±25ppm/°C temperature coefficient) and automotive AEC-Q200 qualification. The primary difference is product status: RG2012P-111-W-T5 is active with higher inventory availability (1100 pcs vs. 735 pcs). This part is suitable for direct replacement in existing designs without modification.

Enhanced Performance Substitutes (Improved Specifications):

RG2012N-111-W-T5, RG2012V-111-P-T1, RG2012V-111-W-T1, and RG2012V-111-W-T5 offer improved temperature coefficient performance (±10ppm/°C or ±5ppm/°C) compared to the original ±25ppm/°C specification. RG2012V-111-P-T1 additionally provides tighter tolerance (±0.02% vs. ±0.05%). All Susumu RG series substitutes maintain anti-sulfur coating and AEC-Q200 automotive qualification. These parts are suitable for applications requiring enhanced thermal stability and precision.

Cross-Manufacturer Alternative:

RT0805WRB07110RL (YAGEO) provides functional equivalence with identical resistance, tolerance, power rating, and package specifications. Temperature coefficient is ±10ppm/°C. This part lacks anti-sulfur coating and automotive AEC-Q200 features present in Susumu parts. Selection of this alternative is appropriate for non-automotive applications or where cross-manufacturer sourcing is required.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-111-W-T5 be used as a direct replacement for RG2012P-111-W-T1?

A: Yes. RG2012P-111-W-T5 is a direct equivalent with identical electrical specifications (110 Ohms ±0.05%, 0.125W, ±25ppm/°C temperature coefficient) and package (0805). Both parts feature anti-sulfur coating and AEC-Q200 automotive qualification. The primary difference is product status and packaging format.

Q: What is the difference between RG2012P-111-W-T1 and RG2012V-111-W-T1?

A: Both parts share identical resistance (110 Ohms), tolerance (±0.05%), power rating (0.125W), and package (0805). The key difference is temperature coefficient: RG2012P-111-W-T1 has ±25ppm/°C while RG2012V-111-W-T1 has ±5ppm/°C. RG2012V-111-W-T1 provides superior thermal stability. Both maintain anti-sulfur coating and AEC-Q200 qualification.

Q: Is RT0805WRB07110RL suitable for automotive applications?

A: RT0805WRB07110RL meets the core electrical requirements (110 Ohms ±0.05%, 0.125W, 0805 package) but lacks anti-sulfur coating and automotive AEC-Q200 qualification present in Susumu RG series parts. For automotive applications requiring AEC-Q200 compliance, Susumu RG series substitutes are recommended.

Q: What does the packaging designation (T1 vs. T5) indicate?

A: The T1 and T5 designations refer to packaging format and tape configuration. Both formats contain identical electrical components in the same 0805 package. Selection between T1 and T5 depends on assembly equipment compatibility and supply chain requirements rather than electrical performance.

Q: Can RG2012V-111-P-T1 be used in place of RG2012P-111-W-T1?

A: Yes. RG2012V-111-P-T1 is compatible with enhanced specifications: 110 Ohms ±0.02% tolerance (tighter than ±0.05%), 0.125W power rating, 0805 package, and ±5ppm/°C temperature coefficient (improved from ±25ppm/°C). All other parameters including anti-sulfur coating and AEC-Q200 qualification are maintained. This part is suitable for applications requiring higher precision and thermal stability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RG2012P-111-W-T5, RG2012N-111-W-T5, RG2012V-111-P-T1, RG2012V-111-W-T1, RG2012V-111-W-T5, and RT0805WRB07110RL) are ROHS3 compliant and REACH unaffected, maintaining environmental compliance requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts including the original RG2012P-111-W-T1 and all substitutes have MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage and handling.
