Substitute Part Grouping Explanation

Substitution of the 05083C102KAT2W is permissible with the 05085C102KAT2A based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 1000 pF (identical)
• Tolerance: ±10% (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 0508 (1220 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Physical Dimensions: 0.050" L x 0.079" W, 0.040" max thickness (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Differing Parameter (Upgrade):

• Voltage - Rated: 25V (main part) vs. 50V (substitute part)

The substitute part operates at a higher voltage rating, providing increased design margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 05083C102KAT2W and 05085C102KAT2A are active products from KYOCERA AVX with identical RoHS3 compliance and REACH unaffected status. The substitute part 05085C102KAT2A provides a higher voltage rating (50V vs. 25V) while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit voltage requirements and design margin considerations. Both parts are suitable for bypass and decoupling applications within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the 05085C102KAT2A (50V) replace the 05083C102KAT2W (25V)?

A: Yes. The substitute part maintains identical capacitance, tolerance, temperature coefficient, operating temperature range, package dimensions, and mounting type. The higher voltage rating provides additional design margin and does not affect performance in circuits operating at or below 25V.

Q: Are the physical dimensions identical between these parts?

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). They are mechanically interchangeable on PCB layouts.

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

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

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the primary difference between these two parts?

A: The rated voltage differs: 05083C102KAT2W is rated at 25V, while 05085C102KAT2A is rated at 50V. All other specifications remain identical.
