LT053D105MAT2X Equivalent & Substitute Parts

Part Overview

The LT053D105MAT2X is a 1 µF ±20% 25V ceramic capacitor in X5R temperature coefficient, 0805 (2012 Metric) package manufactured by KYOCERA AVX. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The X5R temperature coefficient and 0805 form factor are standard specifications for general-purpose bypass and decoupling applications across consumer and industrial electronics.

Substitute Part Grouping Explanation

Substitution for the LT053D105MAT2X is determined by strict equivalence across the following parameters:

Capacitance: 1 µF (exact match required)
Voltage Rating: 25V (exact match required)
Temperature Coefficient: X5R (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature: -55°C ~ 85°C (exact match required)
Moisture Sensitivity: MSL 1 (Unlimited) (exact match required)

Tolerance variations (±20% vs. ±10%) are permitted substitutions when the tighter tolerance does not create design conflicts. Physical dimensions (thickness) may vary within the 0805 package specification without affecting electrical performance or PCB assembly compatibility.

Engineering Selection Recommendations

Direct Equivalents (±20% Tolerance)

C0805C105M3PAC7800 (KEMET) and CC0805MKX5R8BB105 (YAGEO) are active production parts with identical electrical specifications to the LT053D105MAT2X. Both are ROHS3 compliant and carry MSL 1 rating. KEMET part is available in Cut Tape packaging; YAGEO part is available in Tape & Reel. Selection between these two depends on packaging requirements and supply chain availability.

Tighter Tolerance Alternatives (±10% Tolerance)

CL21A105KACLNNC (Samsung Electro-Mechanics) and CGB4B3X5R1E105K055AB (TDK Corporation) provide ±10% tolerance, which is a functional upgrade from the original ±20% specification. Both maintain identical voltage, temperature coefficient, and operating temperature range. CL21A105KACLNNC is active production; CGB4B3X5R1E105K055AB is obsolete. CL21A105KACLNNC is the preferred choice for new designs requiring tighter tolerance control.

Low-Profile Option

CGB4B3X5R1E105M055AB (TDK Corporation, ±20% tolerance) offers the lowest profile at 0.022" (0.55mm) thickness compared to the original 0.037" (0.95mm). This part is obsolete but remains available in inventory. Use only if PCB height constraints require the reduced thickness.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LT053D105MAT2X with a part having ±10% tolerance instead of ±20%?

A: Yes. A tighter tolerance (±10%) is a functional upgrade and does not create compatibility issues. The capacitor will perform within the original design specifications while providing improved accuracy. CL21A105KACLNNC is an active production part with ±10% tolerance suitable for this application.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package and are surface-mount MLCCs. Physical thickness varies between 0.022" and 0.057", but all values fall within the 0805 package specification and will assemble on standard PCB footprints. Verify PCB height clearance if space constraints exist.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) is supplied in smaller quantities on individual tape strips, suitable for low-volume assembly or prototyping. Tape & Reel (TR) is supplied on continuous reels for high-volume automated assembly. Select based on production volume and assembly equipment capability.

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts remain available through existing inventory but are no longer manufactured. For new designs and long-term production, select active production parts: C0805C105M3PAC7800 (KEMET), CC0805MKX5R8BB105 (YAGEO), or CL21A105KACLNNC (Samsung Electro-Mechanics).

Q: Does MSL 1 rating apply to all substitute parts?

A: Yes. All listed substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part. No special moisture control measures are required during storage or assembly.

Q: Can I use a 50V or higher voltage-rated capacitor as a substitute?

A: No. Substitution requires exact voltage rating match at 25V. Using a higher voltage rating introduces unnecessary cost and may affect circuit performance due to different dielectric characteristics.
