Substitute Part Grouping Explanation

Substitution eligibility for the 05086D105MAT2A is determined by the following criteria:

• Capacitance Value: Must be 1 µF (exact match required)
• Package Form Factor: Must be 0508 (1220 Metric) with identical physical dimensions
• Temperature Coefficient: Must be X5R for consistent performance across operating temperature range
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must meet or exceed 6.3V minimum requirement
• Tolerance: Tolerance of ±10% or tighter is acceptable (±20% is the baseline)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 0508ZD105KAT2A meets all substitution criteria with an upgraded voltage rating of 10V and improved tolerance specification of ±10%.

Parameter Comparison

Engineering Selection Recommendations

The 0508ZD105KAT2A is a direct functional substitute for the 05086D105MAT2A. Both parts maintain Active product status and full ROHS3 compliance. The substitute part provides electrical advantages through higher voltage rating (10V versus 6.3V) and improved capacitance tolerance (±10% versus ±20%), while maintaining identical physical dimensions, temperature coefficient, and operating temperature range. The packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may affect procurement and assembly processes but does not impact electrical or mechanical compatibility. Selection between these parts should be based on packaging availability, procurement lead times, and inventory requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 0508ZD105KAT2A replace the 05086D105MAT2A in existing designs?

A: Yes. The substitute part maintains identical capacitance value, package dimensions, temperature coefficient, and operating temperature range. The higher voltage rating and tighter tolerance represent performance improvements with no negative impact on circuit compatibility.

Q: What is the significance of the voltage rating difference?

A: The 05086D105MAT2A is rated at 6.3V, while the 0508ZD105KAT2A is rated at 10V. In applications where the circuit voltage does not exceed 6.3V, both parts are functionally equivalent. The higher voltage rating of the substitute part provides additional safety margin and does not degrade performance in lower-voltage applications.

Q: Does the tolerance difference affect circuit performance?

A: The 0508ZD105KAT2A has ±10% tolerance compared to ±20% for the 05086D105MAT2A. Tighter tolerance means more precise capacitance values. For bypass and decoupling applications, this represents an improvement. If the original design requires ±20% tolerance specifically, the substitute's ±10% tolerance remains acceptable as it falls within the original specification range.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0508 (1220 Metric) package with dimensions of 0.049" L × 0.079" W and maximum thickness of 0.037" (0.94mm). They are mechanically interchangeable on PCB layouts.

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

A: Tape & Reel (TR) is continuous reel packaging for automated assembly. Cut Tape (CT) & Digi-Reel® is pre-cut tape format. Both are suitable for surface mount assembly but may differ in handling, storage, and pick-and-place equipment compatibility. Verify packaging compatibility with your assembly process before procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both the 05086D105MAT2A and 0508ZD105KAT2A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory requirements.
