VJ0603Q2R2DFBAI Equivalent & Substitute Parts

Part Overview

The VJ0603Q2R2DFBAI is a 2.2 pF ceramic capacitor manufactured by Vishay Vitramon, rated for 100V operation with C0G/NP0 temperature coefficient characteristics. This component is designed for RF, microwave, and high-frequency applications requiring high Q and low loss performance in a compact 0603 (1608 Metric) surface mount package.

The VJ0603Q2R2DFBAI is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VJ0603Q2R2DFBAI is determined by the following critical parameters:

• Capacitance value: 2.2 pF
• Tolerance: ±0.5pF
• Voltage rating: 100V minimum
• Temperature coefficient: C0G or NP0
• Package: 0603 (1608 Metric) surface mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The VJ0603D2R2DXBAP meets all substitution criteria and is classified as an active product from the same manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

The VJ0603D2R2DXBAP is the direct substitute for the obsolete VJ0603Q2R2DFBAI. Both components are manufactured by Vishay Vitramon and share identical electrical specifications: 2.2 pF capacitance, ±0.5pF tolerance, 100V voltage rating, and C0G/NP0 temperature coefficient.

The substitute part maintains full mechanical compatibility with the 0603 (1608 Metric) package footprint and is ROHS3 compliant with MSL 1 rating. The VJ0603D2R2DXBAP is currently in active production status, ensuring long-term availability and supply chain continuity.

The operating temperature range of the substitute extends to -55°C ~ 125°C, which covers the lower end of the original part's -55°C ~ 150°C range. For applications requiring operation above 125°C, design verification is necessary.

Frequently Asked Questions (FAQ)

Q: Can the VJ0603D2R2DXBAP be used as a direct replacement for the VJ0603Q2R2DFBAI?

A: Yes. Both parts share identical capacitance (2.2 pF), tolerance (±0.5pF), voltage rating (100V), temperature coefficient (C0G/NP0), and package dimensions (0603 / 1608 Metric). Electrical and mechanical compatibility is confirmed.

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

A: The original VJ0603Q2R2DFBAI operates from -55°C to 150°C, while the substitute VJ0603D2R2DXBAP operates from -55°C to 125°C. For applications requiring sustained operation above 125°C, the temperature specification difference must be evaluated against actual circuit requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the VJ0603Q2R2DFBAI and VJ0603D2R2DXBAP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the physical size difference between these capacitors?

A: Both parts use the 0603 (1608 Metric) package with identical length and width (0.063" L x 0.031" W / 1.60mm x 0.80mm). Maximum thickness differs slightly: 0.036" (0.92mm) for the original versus 0.037" (0.94mm) for the substitute. This 0.01mm difference is within standard PCB assembly tolerances.

Q: Why is the original part obsolete?

A: The VJ0603Q2R2DFBAI is classified as obsolete by the manufacturer. The VJ0603D2R2DXBAP from the VJ HIFREQ series represents the current active product line for this capacitance value and package configuration.
