Equivalent & Substitute Parts for 1111Y5000330FUT

Part Overview

The 1111Y5000330FUT is a 33 pF ceramic capacitor rated at 500V with C0G/NP0 temperature coefficient, manufactured by Knowles Syfer under the FlexiCap™ series. This surface mount MLCC (multilayer ceramic capacitor) is designed for RF, microwave, and high-frequency applications requiring low loss and ultra-low ESR characteristics. The part is currently obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 1111Y5000330FUT is determined by strict equivalence across the following parameters:

• Capacitance value: 33 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500V (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package designation: 1111 (2828 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.110" L × 0.110" W × 0.070" max thickness (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The substitute part 1111Y5000330FQT meets all these criteria and is manufactured by the same supplier (Knowles Syfer) under the same FlexiCap™ series designation.
