LT024D105MAT2C Equivalent & Substitute Parts

Part Overview

The LT024D105MAT2C is a 1 µF ±20% 4V ceramic capacitor in X5R temperature coefficient, manufactured by KYOCERA AVX in 0402 (1005 Metric) surface mount package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing production and repair applications. The X5R temperature coefficient provides stable capacitance across the -55°C to 85°C operating range, making it suitable for general-purpose applications requiring low-profile surface mount solutions.

Substitute Part Grouping Explanation

Substitution for the LT024D105MAT2C is determined by the following critical parameters:

Direct Equivalents maintain identical electrical specifications: 1 µF capacitance, ±20% tolerance, 4V rated voltage, X5R temperature coefficient, and 0402 package format. These parts are functionally interchangeable without circuit redesign.

Upgraded Substitutes increase the rated voltage rating (10V, 16V, or 25V) while maintaining 1 µF capacitance and X5R temperature coefficient. These provide enhanced voltage margin and are backward-compatible in applications where the original 4V rating is sufficient. Upgraded parts may feature improved tolerance specifications (±10% instead of ±20%).

Packaging Variants include different distribution formats (Cut Tape, Tape & Reel) that do not affect electrical performance but influence procurement and assembly processes.

Engineering Selection Recommendations

Direct Equivalent Selection: CGB2T1X5R0G105M022BC is the primary substitute for LT024D105MAT2C. This TDK part maintains identical electrical specifications (1 µF, ±20%, 4V, X5R) and 0402 package format. The part is currently in Active product status, ensuring long-term availability. The reduced thickness (0.009" vs. 0.014") provides design flexibility for space-constrained applications. RoHS3 compliance and REACH Unaffected status align with modern manufacturing requirements.

Alternative Direct Equivalent: CGB2A3X5R0G105M033BB provides equivalent electrical performance with Cut Tape and Digi-Reel packaging options. Slightly reduced thickness (0.013") offers marginal space savings compared to the original part.

Upgraded Voltage Options: For applications requiring enhanced voltage margin, CGB2A1X5R1A105M033BC (10V) or CGB2A1X5R1C105M033BC (16V) maintain ±20% tolerance matching the original specification while providing higher voltage ratings. These upgrades are backward-compatible in circuits designed for 4V operation.

Tolerance Upgrade Path: CGB2A3X5R0G105K033BB offers improved ±10% tolerance at 4V rating, suitable for applications requiring tighter capacitance control without voltage rating changes.

All substitute parts share MSL 1 (Unlimited) moisture sensitivity, identical operating temperature range (-55°C to 85°C), and equivalent ECCN/HTSUS classifications with the original part.

Frequently Asked Questions (FAQ)

Q: Can CGB2T1X5R0G105M022BC directly replace LT024D105MAT2C without circuit modification?

A: Yes. Both parts specify 1 µF ±20% at 4V with X5R temperature coefficient in 0402 package. Electrical performance is identical. The reduced thickness of CGB2T1X5R0G105M022BC (0.009" vs. 0.014") is a physical advantage with no negative impact on circuit function.

Q: What is the difference between direct equivalents and upgraded substitutes?

A: Direct equivalents (CGB2A3X5R0G105M033BB, CGB2T1X5R0G105M022BC) maintain the original 4V voltage rating and ±20% tolerance. Upgraded substitutes increase voltage rating to 10V, 16V, or 25V while maintaining 1 µF capacitance. Upgraded parts are backward-compatible in 4V circuits but occupy the same 0402 footprint.

Q: Are all substitute parts RoHS compliant?

A: All TDK substitute parts listed are RoHS3 Compliant. The original KYOCERA AVX part (LT024D105MAT2C) shows REACH Unaffected status. All substitutes maintain REACH Unaffected classification.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects procurement and assembly logistics only. Electrical specifications remain identical regardless of distribution format. Select based on production volume and assembly equipment compatibility.

Q: Which substitute offers the best long-term availability?

A: CGB2T1X5R0G105M022BC carries Active product status, indicating ongoing manufacturing and distribution support. Parts marked Obsolete may face future availability constraints.

Q: Can I use a 10V or 16V rated capacitor in place of the 4V original?

A: Yes, for backward compatibility. Higher voltage-rated capacitors (CGB2A1X5R1A105M033BC at 10V, CGB2A1X5R1C105M033BC at 16V) are electrically suitable for circuits designed for 4V operation. The higher voltage rating provides additional safety margin without affecting circuit performance.
