Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-2940-C-T5 is determined by the following critical parameters that must remain constant across all alternatives:

Fixed Parameters (Non-Negotiable):

• Resistance value: 294 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Tolerance: The main part specifies ±0.25%. Substitute parts with equal or tighter (lower) tolerance values are functionally compatible, as they meet or exceed the original 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 active alternatives.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All four substitute parts are active products with current manufacturing status, providing supply chain continuity for the obsolete RG2012V-2940-C-T5. Selection among substitutes is based on tolerance requirements and packaging format:

RG2012V-2940-W-T5 and RG2012V-2940-W-T1 (±0.05% tolerance) provide the most direct functional upgrade with tighter tolerance specification while maintaining identical electrical and thermal characteristics. Both are suitable for applications requiring improved accuracy over the original ±0.25% specification.

RG2012V-2940-B-T5 (±0.1% tolerance) offers a mid-range tolerance improvement and is appropriate for applications where moderate precision enhancement is beneficial.

RG2012V-2940-P-T1 (±0.02% tolerance) provides the highest precision specification and is selected for applications demanding maximum accuracy and stability.

All substitutes maintain AEC-Q200 automotive qualification, anti-sulfur construction, RoHS3 compliance, and identical operating temperature range (-55°C ~ 155°C). Mechanical compatibility is assured through identical 0805 package dimensions and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-2940-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All substitute parts maintain identical resistance value (294 Ohms), power rating (0.125W), package format (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive certifications (AEC-Q200). The substitutes feature equal or improved tolerance specifications, making them functionally compatible.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-2940-W-T5 and RG2012V-2940-W-T1 offer ±0.05% tolerance, RG2012V-2940-B-T5 offers ±0.1% tolerance, and RG2012V-2940-P-T1 offers ±0.02% tolerance. All are tighter than the original ±0.25% specification.

Q: What does the "T5" and "T1" designation indicate?

A: The T5 and T1 designations refer to packaging format. Both indicate Tape & Reel (TR) packaging. The specific designation relates to reel configuration and tape specifications for automated assembly processes.

Q: Are all substitutes suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, meeting automotive reliability and environmental requirements identical to the original part.

Q: Can I use a substitute with tighter tolerance in place of the original?

A: Yes. A component with tighter tolerance (lower percentage value) exceeds the original specification and is fully compatible. For example, a ±0.05% part meets or exceeds any requirement specified for ±0.25%.

Q: Are there any mechanical compatibility concerns?

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

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All parts and substitutes carry this rating, ensuring no special storage or handling procedures are necessary.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant, maintaining environmental and regulatory compliance identical to the original part.
