Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 05085C102MAT2W is determined by the following critical parameters:

• Capacitance Value: Must be 1000 pF (no deviation permitted)
• Voltage Rating: Must be 50V or higher
• Temperature Coefficient: Must be X7R
• Package Configuration: Must be 0508 (1220 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 05085C102KAT2A meets all these criteria. The primary difference is tolerance specification: the main part carries ±20% tolerance, while the substitute carries ±10% tolerance. This represents an upgrade in tolerance performance while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both 05085C102MAT2W and 05085C102KAT2A are active production components with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on tolerance requirements for the specific application:

• 05085C102MAT2W (±20% tolerance): Suitable for general-purpose bypass and decoupling applications where wider tolerance bands are acceptable.
• 05085C102KAT2A (±10% tolerance): Suitable for applications requiring tighter capacitance tolerance control. This part provides improved tolerance performance while maintaining identical electrical ratings, package dimensions, and compliance certifications.

Both parts are manufactured by KYOCERA AVX using identical package geometry, thermal characteristics, and low ESL reverse geometry design. Interchangeability is confirmed at the mechanical and electrical interface level.

Frequently Asked Questions (FAQ)

Q: Can 05085C102KAT2A replace 05085C102MAT2W in existing designs?

A: Yes. The substitute part maintains identical capacitance value, voltage rating, temperature coefficient, package configuration, and operating temperature range. The primary difference is improved tolerance (±10% vs ±20%), which represents a direct upgrade in performance specification.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts use the 0508 (1220 Metric) package with identical dimensions: 0.050" L x 0.079" W (1.27mm x 2.00mm) and maximum thickness of 0.040" (1.02mm). PCB footprints and assembly processes are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both 05085C102MAT2W and 05085C102KAT2A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Compliance certifications are equivalent.

Q: What is the significance of the tolerance difference?

A: Tolerance specifies the allowable deviation from the nominal 1000 pF capacitance value. The ±20% tolerance allows values between 800 pF and 1200 pF, while ±10% tolerance allows values between 900 pF and 1100 pF. Applications requiring tighter capacitance control should specify the ±10% part.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
