0402ZD103MAT4A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 0402ZD103MAT4A is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX in 0402 (1005 Metric) surface mount package. This component operates at 10V rated voltage with X5R temperature coefficient and ±20% capacitance tolerance. The part is currently active in production with 1100 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when design requirements allow for improved specifications (higher voltage rating or tighter tolerance), or when alternative manufacturers' components meet the electrical and mechanical requirements of the application.

Engineering Selection Recommendations

For Active Production Designs:

Select from KYOCERA AVX parts with Active product status: 0402YD103KAT2A, 0402ZD103KAT2A, KGM05AR51E103KH, or KGM05AR51E103MH. These components maintain full manufacturing support and are recommended for new designs.

The 0402YD103KAT2A offers improved specifications with 16V rating and ±10% tolerance while maintaining Active status and high inventory availability (61499 units).

The 0402ZD103KAT2A provides equivalent voltage rating to the original part with tighter ±10% tolerance and Active product status.

The KGM05AR51E103KH and KGM05AR51E103MH provide elevated voltage margin at 25V, suitable for applications requiring additional design headroom.

For Legacy or Existing Designs:

The Murata GRM155R61A103KA01D and GRM155R61C103KA01D are electrically compatible but carry "Not For New Designs" status. These parts remain available in inventory but should not be selected for new product development. Use only when maintaining existing designs or when supply constraints require legacy component selection.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0402YD103KAT2A for 0402ZD103MAT4A?

A: Yes. The 0402YD103KAT2A is a direct substitute with identical capacitance (10000 pF), package (0402), and temperature coefficient (X5R). The higher voltage rating (16V vs. 10V) and tighter tolerance (±10% vs. ±20%) represent improvements. Physical dimensions remain compatible.

Q: What is the difference between ±10% and ±20% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 10000 pF capacitance value. ±20% allows deviation from 8000 pF to 12000 pF. ±10% allows deviation from 9000 pF to 11000 pF. Applications requiring tighter capacitance control should specify ±10% parts.

Q: Why would I choose a 25V rated capacitor instead of 10V?

A: Higher voltage ratings provide design margin and improve component reliability under transient voltage conditions. The KGM05AR51E103KH (25V) and KGM05AR51E103MH (25V) are suitable when circuit design allows for elevated voltage specifications without cost or space constraints.

Q: Are Murata GRM parts compatible with KYOCERA AVX parts?

A: Yes, electrically and mechanically. Both manufacturers produce 0402 (1005 Metric) ceramic capacitors with identical X5R characteristics and operating temperature ranges. However, Murata GRM155R61A103KA01D and GRM155R61C103KA01D carry "Not For New Designs" status and should be used only for legacy design maintenance.

Q: What does "Not For New Designs" mean?

A: This product status indicates the manufacturer is discontinuing or has discontinued active support for the component. Existing inventory may be available, but the part should not be selected for new product development. Use KYOCERA AVX Active parts for new designs.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes, provided all parts meet the circuit's voltage and tolerance requirements. All listed substitutes share identical 0402 package dimensions, surface mount characteristics, and X5R temperature coefficient, enabling direct PCB footprint compatibility.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard industrial conditions indefinitely.
