VJ1206A2R2CXCMP Equivalent & Substitute Parts

Part Overview

The VJ1206A2R2CXCMP is a 2.2 pF ceramic capacitor manufactured by Vishay Vitramon in the VJ series. This surface mount multilayer ceramic capacitor (MLCC) operates at 200V rated voltage with C0G/NP0 temperature coefficient, suitable for general purpose applications requiring stable capacitance across temperature ranges from -55°C to 150°C. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are maintained while offering enhanced performance characteristics or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VJ1206A2R2CXCMP are identified based on the following criteria:

Maintained Parameters (Required for Substitution):

• Capacitance: 2.2 pF
• Tolerance: ±0.25pF
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 150°C
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Thickness (Max): 0.067" (1.70mm)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May be equal or higher than the original specification

The VJ1206A2R2CXEAC qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering an upgraded voltage rating of 500V, providing enhanced design margin for applications requiring higher voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the VJ1206A2R2CXCMP and VJ1206A2R2CXEAC are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating. The VJ1206A2R2CXEAC provides a higher voltage rating (500V versus 200V) while maintaining identical capacitance, tolerance, temperature coefficient, and physical package specifications. Selection between these parts depends on circuit voltage requirements. The substitute part is suitable for applications where the original 200V specification is adequate, as the higher voltage rating does not degrade performance in lower voltage applications. Both parts are manufactured by Vishay Vitramon and carry equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can VJ1206A2R2CXEAC replace VJ1206A2R2CXCMP in all applications?

A: Yes, provided the circuit voltage does not exceed 500V. The substitute part maintains identical capacitance (2.2 pF), tolerance (±0.25pF), temperature coefficient (C0G/NP0), and physical dimensions. The higher voltage rating of the substitute part does not affect performance in circuits operating at or below 200V.

Q: Are the physical packages identical?

A: Yes. Both parts use the 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.067" (1.70mm). They are pin-compatible and require no PCB layout modifications.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G (also designated NP0) indicates a temperature coefficient of 0 ppm/°C, meaning capacitance remains stable across the operating temperature range of -55°C to 150°C. Both parts maintain this specification.

Q: Are both parts RoHS compliant?

A: Yes. Both VJ1206A2R2CXCMP and VJ1206A2R2CXEAC are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), indicating no special moisture handling requirements during storage or assembly.

Q: What is the tolerance specification and how does it affect circuit design?

A: Both parts have a tolerance of ±0.25pF. For a 2.2 pF capacitor, this represents approximately ±11.4% tolerance, which is typical for ceramic capacitors in this value range and should be considered in circuit design calculations.
