KYOCERA AVX 0508ZD105MAT2A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 0508ZD105MAT2A is a 1 µF ceramic capacitor rated at 10V with X5R temperature coefficient, designed for surface mount applications in the 0508 (1220 Metric) package. This multilayer ceramic capacitor (MLCC) is specified for bypass and decoupling applications with low ESL characteristics achieved through reverse geometry design. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic assemblies requiring stable capacitance across operating temperatures from -55°C to 85°C.

Substitute parts are identified when equivalent electrical performance can be maintained while accommodating supply chain variations, packaging preferences, or tolerance requirements within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0508ZD105MAT2A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 1 µF (no deviation)
• Voltage Rating: Must be 10V or higher (equal or greater rating acceptable)
• Temperature Coefficient: Must be X5R (ensures stable capacitance across -55°C to 85°C)
• Package / Case: Must be 0508 (1220 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.049" L x 0.079" W footprint and 0.037" maximum thickness
• Compliance: Must maintain ROHS3 and MSL 1 ratings

The substitute part 0508ZD105KAT2A meets all critical parameters with one modification: tolerance is tightened from ±20% to ±10%, representing an upgrade in capacitance accuracy. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), but electrical and mechanical specifications remain fully compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the 0508ZD105MAT2A and 0508ZD105KAT2A are active production parts from KYOCERA AVX with full ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on:

0508ZD105MAT2A is appropriate when standard ±20% tolerance meets circuit requirements and Tape & Reel packaging is preferred for high-volume automated assembly.

0508ZD105KAT2A is appropriate when tighter ±10% capacitance tolerance is required for improved circuit performance or when Cut Tape & Digi-Reel® packaging aligns with procurement and assembly workflows. The tighter tolerance represents an upgrade path with no electrical or mechanical compromise.

Both parts are suitable for bypass and decoupling applications across the full -55°C to 85°C operating range. Footprint compatibility is guaranteed, and no circuit redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can 0508ZD105KAT2A be used as a direct replacement for 0508ZD105MAT2A?

A: Yes. Both parts share identical capacitance (1 µF), voltage rating (10V), temperature coefficient (X5R), package (0508), and physical dimensions. The substitute has tighter tolerance (±10% versus ±20%), which is an improvement. No circuit modifications are required.

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

A: Tape & Reel (TR) is continuous reel packaging for high-speed automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® is pre-cut tape with individual component sections, suitable for lower-volume assembly or manual handling. Both formats contain identical components; packaging choice depends on assembly equipment and volume requirements.

Q: Does the ±10% tolerance of 0508ZD105KAT2A affect circuit compatibility?

A: No. Tighter tolerance (±10%) is a specification upgrade that improves capacitance accuracy without affecting electrical performance or compatibility. If the original design accepted ±20% tolerance, it will accept ±10% tolerance.

Q: Are both parts RoHS compliant?

A: Yes. Both 0508ZD105MAT2A and 0508ZD105KAT2A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for unrestricted storage and assembly environments.

Q: Can these parts be used interchangeably in bypass and decoupling applications?

A: Yes. Both parts are specified for bypass and decoupling applications with identical X5R temperature stability across -55°C to 85°C. Electrical performance is equivalent within their respective tolerance bands.
