Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0508YC102MAT2A is determined by the following critical parameters:

• Capacitance Value: Must remain 1000 pF (no tolerance for deviation)
• Package / Case: Must be 0508 (1220 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R for thermal stability equivalence
• Operating Temperature Range: Must support -55°C ~ 125°C
• Voltage Rating: May be equal to or greater than 16V (uprating is acceptable)
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitute part 05085C102KAT2A meets all mandatory parameters while providing an upgraded voltage rating (50V) and improved tolerance (±10%), making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The 05085C102KAT2A serves as a direct substitute for the 0508YC102MAT2A in bypass and decoupling applications. Both parts maintain identical mechanical compatibility, thermal performance, and regulatory compliance. The substitute part provides enhanced electrical specifications through increased voltage rating (50V versus 16V) and improved capacitance tolerance (±10% versus ±20%), making it suitable for circuits where the original 16V rating is adequate. Both parts are ROHS3 compliant with MSL 1 rating and maintain the same low ESL reverse geometry design. Selection between these parts depends on circuit voltage requirements and tolerance specifications rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can 05085C102KAT2A replace 0508YC102MAT2A in all applications?

A: Yes, provided the circuit voltage rating does not exceed 50V. The substitute part's higher voltage rating and tighter tolerance make it electrically compatible with any application designed for the original part.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0508 (1220 Metric) package with identical length (0.050" / 1.27mm), width (0.079" / 2.00mm), and maximum thickness (0.040" / 1.02mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the significance of the ±10% tolerance improvement in the substitute part?

A: The tighter tolerance in 05085C102KAT2A (±10% versus ±20%) provides improved capacitance accuracy. This is beneficial in precision circuits where capacitance value stability is critical, though both parts meet the same X7R temperature coefficient specification.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: What does "Low ESL (Reverse Geometry)" mean for these parts?

A: Low ESL (Equivalent Series Inductance) design reduces parasitic inductance, improving high-frequency performance in bypass and decoupling applications. Reverse geometry refers to the internal electrode configuration that achieves this characteristic. Both parts incorporate this feature identically.
