0402YA2R0BAT2A Equivalent & Substitute Parts

Part Overview

The 0402YA2R0BAT2A is a 2 pF ceramic capacitor manufactured by KYOCERA AVX with a rated voltage of 16V, C0G/NP0 temperature coefficient, and 0402 (1005 Metric) surface mount package. This part is actively produced and widely used in general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. Substitute parts are necessary when higher voltage ratings are required for circuit protection, when preferred manufacturers are unavailable, or when design specifications call for enhanced performance characteristics such as tighter tolerances or lower ESL.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0402YA2R0BAT2A is determined by strict equivalence in the following parameters:

• Capacitance value: 2 pF (exact match required)
• Tolerance: ±0.1pF or tighter (±0.05pF acceptable)
• Temperature coefficient: C0G/NP0 (mandatory for stability)
• Package: 0402 (1005 Metric) surface mount (physical and electrical compatibility)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• Voltage rating: 16V minimum (higher ratings provide design margin and are acceptable)
• RoHS3 compliance and MSL 1 rating (environmental and handling compatibility)

All substitute parts listed maintain identical physical dimensions, mounting characteristics, and electrical performance within the specified operating envelope. Voltage rating upgrades from 16V to 50V represent design improvements that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

For active production designs, select from parts with Active product status: 0402YA2R0BAT2A (original 16V specification), 04025A2R0BAT2A (KYOCERA AVX 50V upgrade), C0402C209B5GAC7867 (KEMET 50V), or CQ0402ARNPO9BN2R0 (YAGEO 50V with tighter ±0.05pF tolerance).

Parts designated "Not For New Designs" (C1005C0G1H020B050BA from TDK and GRM1555C1H2R0BA01D from Murata) are suitable for legacy system maintenance and repair applications only. These parts maintain full electrical and mechanical compatibility but should not be specified for new circuit designs.

All listed substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 16V original part?

A: Yes. A 50V rated capacitor is a direct substitute for a 16V application. Higher voltage ratings provide additional design margin and do not affect circuit performance when the capacitance, tolerance, temperature coefficient, and package remain identical.

Q: What is the difference between ±0.1pF and ±0.05pF tolerance?

A: Both tolerances are acceptable substitutes. The ±0.05pF tolerance (CQ0402ARNPO9BN2R0) provides tighter capacitance control, which may be beneficial in precision RF or timing circuits. For general-purpose applications, ±0.1pF tolerance is sufficient.

Q: Are parts marked "Not For New Designs" unsuitable for my application?

A: Parts with "Not For New Designs" status are electrically and mechanically equivalent and function identically in existing circuits. This designation indicates the manufacturer has discontinued active development. These parts are appropriate for repair, maintenance, and legacy system support. For new designs, prioritize parts with Active status.

Q: Does the 0402 package dimension vary between manufacturers?

A: No. The 0402 (1005 Metric) package is a standardized industry specification: 0.039" L × 0.020" W (1.00mm × 0.50mm) with maximum thickness of 0.022" (0.55mm). All listed parts conform to this standard and are mechanically interchangeable.

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

A: C0G and NP0 designations are equivalent and indicate zero temperature coefficient. Capacitance remains stable across the -55°C to 125°C operating range, making these parts suitable for applications requiring predictable performance across temperature variations.
