Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VJ0805Q2R7CFBAI is determined by the following critical parameters:

• Capacitance Value: 2.7 pF (exact match required)
• Tolerance: ±0.25pF (exact match required)
• Voltage Rating: 100V (minimum requirement; higher ratings are acceptable)
• Temperature Coefficient: C0G/NP0 (required for frequency stability)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly process compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The VJ0805D2R7CXBAR meets all substitution criteria and is classified as an active product from the same manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

The VJ0805D2R7CXBAR is the recommended substitute for the obsolete VJ0805Q2R7CFBAI. Both components are manufactured by Vishay Vitramon and share identical electrical specifications for capacitance, tolerance, voltage rating, and temperature coefficient. Physical dimensions and package specifications are identical, ensuring direct compatibility in existing PCB layouts.

The substitute part is currently in active production status with confirmed inventory availability (909 pcs), whereas the original part is obsolete. Both components maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and handling requirements.

The operating temperature range of the substitute part (-55°C ~ 125°C) is narrower than the original part (-55°C ~ 150°C). Applications requiring operation above 125°C must be evaluated against actual circuit requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can the VJ0805D2R7CXBAR be used as a direct replacement for the VJ0805Q2R7CFBAI?

A: Yes. Both parts share identical capacitance (2.7 pF), tolerance (±0.25pF), voltage rating (100V), temperature coefficient (C0G/NP0), and package dimensions (0805 / 2012 Metric). Physical and electrical compatibility is confirmed.

Q: What is the difference in operating temperature range between these parts?

A: The original VJ0805Q2R7CFBAI operates from -55°C to 150°C, while the substitute VJ0805D2R7CXBAR operates from -55°C to 125°C. Applications requiring sustained operation above 125°C should confirm circuit requirements before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the VJ0805Q2R7CFBAI and VJ0805D2R7CXBAR are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the availability status of each part?

A: The VJ0805Q2R7CFBAI is obsolete with 733 pcs in current stock. The VJ0805D2R7CXBAR is an active product with 909 pcs in current stock, ensuring long-term availability for production requirements.

Q: Are there any differences in physical dimensions or mounting requirements?

A: No. Both parts are 0805 (2012 Metric) surface-mount components with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum thickness (0.057" / 1.45mm). PCB footprints and assembly processes are identical.
