Equivalent & Substitute Parts for 05085C103MAT2A

Part Overview

The 05085C103MAT2A is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 50V with X7R temperature coefficient and 0508 (1220 Metric) package configuration. This component is actively produced and widely used in bypass and decoupling applications. Substitute parts become necessary due to supply constraints, inventory availability, or specific tolerance and compliance requirements in production environments.

Substitute Part Grouping Explanation

Substitution eligibility for the 05085C103MAT2A is determined by strict equivalence in the following parameters:

• Capacitance value: 10000 pF (exact match required)
• Voltage rating: 50V (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package / Case: 0508 (1220 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS and REACH compliance status (ROHS3 Compliant, REACH Unaffected)

Tolerance variations (±20% vs ±10%) and minor dimensional differences within the 0508 package specification do not disqualify substitution. Moisture sensitivity level remains constant at MSL 1 across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

05085C103KAT2A (KYOCERA AVX Upgrade): This substitute offers tighter tolerance specification (±10% vs ±20%) while maintaining identical electrical and mechanical parameters. Both parts are Active status products from the same manufacturer, ensuring consistent supply chain reliability and identical package geometry. Selection of this upgrade is appropriate for applications requiring improved capacitance accuracy without design modification.

LLL215R71H103MA11L (Murata Electronics Direct): This substitute meets all core electrical specifications and compliance requirements. However, this part carries Last Time Buy status, indicating discontinued production. Dimensional variations exist: length is 0.049" (1.25mm) versus 0.050" (1.27mm), and thickness is significantly reduced at 0.020" (0.50mm) versus 0.040" (1.02mm). These dimensional differences remain within 0508 package classification but require verification for PCB layout compatibility, particularly in space-constrained applications. Selection is limited to inventory depletion scenarios or applications where reduced thickness provides design advantage.

Frequently Asked Questions (FAQ)

Q: Can 05085C103KAT2A directly replace 05085C103MAT2A without design changes?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical ratings, temperature coefficient, package designation, and physical dimensions. The tolerance improvement (±10% vs ±20%) represents a specification upgrade with no compatibility concerns.

Q: Is LLL215R71H103MA11L suitable for all applications using 05085C103MAT2A?

A: Electrical compatibility is confirmed. However, dimensional differences must be evaluated: the Murata part is 0.001" shorter in length and 0.020" thinner. PCB layout verification is required to confirm clearance and mechanical fit, particularly in high-density assemblies or applications with height constraints.

Q: What is the significance of Last Time Buy status for LLL215R71H103MA11L?

A: Last Time Buy indicates the manufacturer has discontinued this product line. Existing inventory is available but future procurement is not possible. This part should be selected only when current stock is sufficient for project requirements or when inventory depletion is acceptable.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts carry ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects capacitance accuracy within specified limits. The ±10% tolerance of 05085C103KAT2A provides tighter control around the 10000 pF nominal value. Applications sensitive to capacitance variation should specify the tighter tolerance part; general bypass and decoupling applications typically accept ±20% tolerance.
