Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VJ0805Q2R2DXCAC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2.2 pF (exact match required)
• Tolerance: ±0.5pF (exact match required)
• Voltage rating: 200V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (required for frequency stability)
• Package: 0805 (2012 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount, MLCC (assembly compatibility)
• Operating temperature range: Must support -55°C minimum and 150°C maximum
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The VJ0805D2R2DXCAT meets all substitution criteria as an active product alternative with identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The VJ0805D2R2DXCAT is the manufacturer-recommended substitute for the obsolete VJ0805Q2R2DXCAC. Both components are manufactured by Vishay Vitramon and maintain identical electrical and mechanical specifications across all critical parameters: capacitance, tolerance, voltage rating, temperature coefficient, package configuration, and compliance certifications.

The substitute part is currently in active production status with confirmed inventory availability, ensuring reliable supply chain access. Both components carry ROHS3 compliance and MSL 1 rating, meeting regulatory and environmental requirements for modern electronics manufacturing.

The operating temperature range difference (-55°C to 125°C for the substitute versus -55°C to 150°C for the original) represents the only specification variance. Applications requiring operation above 125°C must evaluate this limitation against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can VJ0805D2R2DXCAT be used as a direct replacement for VJ0805Q2R2DXCAC?

A: Yes. Both components share identical capacitance (2.2 pF), tolerance (±0.5pF), voltage rating (200V), temperature coefficient (C0G/NP0), and 0805 package configuration. The substitute is the manufacturer-recommended alternative for the obsolete original part.

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

A: The original part operates from -55°C to 150°C, while the substitute operates from -55°C to 125°C. Applications requiring sustained operation above 125°C must assess whether this reduced upper temperature limit affects circuit performance.

Q: Are both parts RoHS compliant?

A: Yes. Both VJ0805Q2R2DXCAC and VJ0805D2R2DXCAT are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both components use the 0805 (2012 Metric) package with identical physical dimensions: 2.00mm length, 1.25mm width, and 1.45mm maximum thickness. PCB footprints are directly compatible.

Q: Why is the original part listed as obsolete?

A: The VJ0805Q2R2DXCAC has been discontinued by the manufacturer. The VJ0805D2R2DXCAT represents the active production equivalent and is the recommended path for new designs and component replenishment.
