Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-3090-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 309 Ohms
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur construction

Allowable Variation Parameters:

• Tolerance: Substitute parts with equal or tighter (lower) tolerance values are acceptable
• Product status: Active alternatives are preferred over obsolete status
• Packaging format: Tape & Reel (TR) is compatible with the original packaging specification

All substitute parts listed maintain identical mechanical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and electrical characteristics except for tolerance specifications, which are improved in the substitute options.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RG2012V-3090-P-T1

The RG2012V-3090-P-T1 offers the highest tolerance specification at ±0.02%, providing superior precision for applications requiring tight resistance accuracy. This part maintains full electrical and mechanical compatibility with the RG2012V-3090-C-T5 while offering active product status and current manufacturing availability.

Secondary Substitute: RG2012V-3090-W-T5

The RG2012V-3090-W-T5 provides ±0.05% tolerance with active status and represents a balanced alternative for applications where the original ±0.25% tolerance is acceptable but improved precision is beneficial. This part shares identical packaging specifications and automotive qualifications.

Tertiary Substitute: RG2012V-3090-B-T5

The RG2012V-3090-B-T5 delivers ±0.1% tolerance with active product status. This option is suitable for applications where moderate tolerance improvement over the original specification is required while maintaining cost efficiency.

Quaternary Substitute: RG2012V-3090-W-T1

The RG2012V-3090-W-T1 provides ±0.05% tolerance with active status. This part is functionally equivalent to RG2012V-3090-W-T5 with identical electrical specifications.

All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur construction, ensuring suitability for automotive and harsh environment applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-3090-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical resistance value (309 Ohms), power rating (0.125W), package format (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualifications (AEC-Q200). The substitutes differ only in tolerance specification, which is equal to or tighter than the original part.

Q: What is the primary advantage of using substitute parts over the original RG2012V-3090-C-T5?

A: The original part is classified as obsolete. All substitute parts carry active product status, ensuring continued manufacturing availability and supply chain reliability. Additionally, substitute parts offer improved tolerance specifications ranging from ±0.1% to ±0.02%, compared to the original ±0.25%.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All parts share identical mechanical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), maximum seated height (0.020" / 0.50mm), and 0805 (2012 Metric) package format. PCB footprints and assembly processes remain unchanged.

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

A: The RG2012V-3090-P-T1 offers the tightest tolerance at ±0.02%, providing the highest precision for applications requiring strict resistance accuracy.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, meeting automotive industry reliability and environmental standards.

Q: What is the difference between the T5 and T1 packaging designations?

A: Both designations refer to Tape & Reel (TR) packaging format. The suffix indicates different tape specifications within the TR packaging standard. Both are compatible with standard SMD assembly equipment.

Q: Can the RG2012V-3090-C-T5 be used interchangeably with substitute parts in existing designs?

A: Yes. The substitute parts are direct functional equivalents with identical electrical performance within their respective tolerance bands. No circuit redesign or validation is required for substitution.
