Substitute Part Grouping Explanation

Substitution of the RG2012V-1051-C-T5 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 1.05 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (physical and electrical compatibility)
• Power rating: 0.125W (1/8W) (thermal and current handling capacity)
• Composition: Thin Film (electrical performance characteristics)
• Automotive qualification: AEC-Q200 (application requirement)
• Anti-sulfur coating: Present (environmental protection requirement)
• Temperature coefficient: ±5ppm/°C (thermal stability)
• Operating temperature range: -55°C ~ 155°C (environmental specification)

Allowable Variation Parameter:

• Tolerance: Substitute parts with equal or tighter (lower) tolerance values are functionally equivalent. The RG2012V-1051-C-T5 specifies ±0.25% tolerance. Substitute parts with ±0.1%, ±0.05%, or ±0.02% tolerance maintain full compatibility and provide enhanced precision capability.

All substitute parts listed maintain identical mechanical dimensions, termination count, RoHS compliance, and REACH status as the original component.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (RG2012V-1051-B-T5, RG2012V-1051-P-T1, RG2012V-1051-W-T1, and RG2012V-1051-W-T5) are direct functional equivalents to the RG2012V-1051-C-T5 for applications requiring 1.05 kOhms resistance in 0805 package format with automotive AEC-Q200 qualification.

Product Status Consideration: The original RG2012V-1051-C-T5 is classified as obsolete. All substitute parts carry active product status, ensuring continued availability and supply chain support.

Tolerance Selection:

• RG2012V-1051-B-T5 (±0.1% tolerance): Provides improved precision over the original ±0.25% specification while maintaining active status.
• RG2012V-1051-W-T5 (±0.05% tolerance): Offers enhanced precision with active status and highest inventory availability (1089 Pcs).
• RG2012V-1051-W-T1 (±0.05% tolerance): Equivalent precision to RG2012V-1051-W-T5 with active status.
• RG2012V-1051-P-T1 (±0.02% tolerance): Provides the highest precision specification available in this series.

All substitute parts maintain identical electrical performance characteristics, thermal specifications, and mechanical compatibility with the original component. Selection between substitutes depends on application-specific tolerance requirements and packaging format preferences (Tape & Reel format for all active alternatives).

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1051-B-T5, RG2012V-1051-P-T1, RG2012V-1051-W-T1, and RG2012V-1051-W-T5 be used as direct replacements for RG2012V-1051-C-T5?

A: Yes. All substitute parts are direct functional equivalents. They maintain identical resistance value (1.05 kOhms), power rating (0.125W), package format (0805), composition (thin film), automotive qualification (AEC-Q200), and operating specifications. The substitute parts feature equal or tighter tolerance specifications, which provide enhanced precision without compromising compatibility.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-1051-B-T5 specifies ±0.1% tolerance, RG2012V-1051-W-T5 and RG2012V-1051-W-T1 specify ±0.05% tolerance, and RG2012V-1051-P-T1 specifies ±0.02% tolerance. All other electrical and mechanical parameters remain identical. Tighter tolerance specifications provide greater precision for applications requiring closer resistance values.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts, including the original RG2012V-1051-C-T5 and all substitutes, share identical physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm). They are fully compatible with existing PCB layouts and assembly processes.

Q: What is the packaging format for the substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is the standard packaging for high-volume production applications. This format differs from the original part's packaging designation but maintains full electrical and mechanical compatibility.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur coating, matching the original component's automotive-grade specifications. All parts are ROHS3 compliant and REACH unaffected.

Q: Which substitute part should be selected for maximum precision?

A: RG2012V-1051-P-T1 provides the tightest tolerance specification at ±0.02%, compared to the original ±0.25%. This part is suitable for applications requiring the highest resistance accuracy. All substitute parts maintain identical temperature coefficient (±5ppm/°C) and operating temperature range (-55°C ~ 155°C).

Q: What is the current availability status of the substitute parts?

A: All substitute parts carry active product status with confirmed inventory: RG2012V-1051-B-T5 (806 Pcs), RG2012V-1051-P-T1 (741 Pcs), RG2012V-1051-W-T1 (722 Pcs), and RG2012V-1051-W-T5 (1089 Pcs). The original RG2012V-1051-C-T5 is obsolete with 1029 Pcs remaining in stock.
