0201YA3R9BAT2A Equivalent & Substitute Parts

Part Overview

The 0201YA3R9BAT2A is a 3.9 pF ceramic capacitor manufactured by KYOCERA AVX, rated at 16V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained while offering alternative voltage ratings or manufacturer options.

Substitute Part Grouping Explanation

Substitution eligibility for the 0201YA3R9BAT2A is determined by the following criteria:

Mandatory Matching Parameters:

Capacitance: 3.9 pF
Tolerance: ±0.1pF
Temperature Coefficient: C0G, NP0
Package / Case: 0201 (0603 Metric)
Physical Dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C ~ 125°C

Allowable Variation:

Voltage Rating: Substitute parts may have equal or higher voltage ratings than the original 16V specification. Higher voltage ratings provide additional design margin and are electrically compatible in applications designed for 16V operation.

Compliance Requirements:

RoHS3 Compliance: Required
MSL Rating: 1 (Unlimited) or equivalent

Four substitute parts meet these criteria, offered by three manufacturers: KYOCERA AVX, YAGEO, and Murata Electronics.

Compliance Status: All substitute parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can a 25V or 50V rated capacitor replace a 16V rated capacitor? A: Yes. Higher voltage ratings are electrically compatible in 16V applications. The capacitor will operate within its design specifications with additional voltage margin. Physical dimensions and electrical characteristics (capacitance, tolerance, temperature coefficient) remain identical.

Q: Are all substitute parts pin-compatible with the original 0201YA3R9BAT2A? A: Yes. All substitute parts use the identical 0201 (0603 Metric) package with matching physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum thickness (0.013" / 0.33mm). Surface mount assembly compatibility is maintained.

Q: What is the significance of C0G/NP0 temperature coefficient? A: C0G and NP0 designations indicate zero temperature coefficient ceramic dielectric material. Capacitance remains stable across the -55°C to 125°C operating temperature range, with negligible drift. This characteristic is maintained across all substitute parts.

Q: Do all parts meet the same moisture sensitivity requirements? A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake requirements. Handling and storage procedures are identical.

Q: Which substitute offers the best inventory availability? A: Murata Electronics GRM0335C1E3R9BA01D offers the highest stock level at 85,103 units, followed by KYOCERA AVX KGM03ACG1E3R9BH at 36,353 units.
