08055C103JAT2M Equivalent & Substitute Parts

Part Overview

The 08055C103JAT2M is a 10000 pF ±5% 50V ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient in 0805 (2012 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 10000 pF capacitance, ±5% tolerance, 50V rated voltage, X7R temperature coefficient, and -55°C ~ 125°C operating temperature range. These parts are interchangeable within the same circuit application and occupy the same 0805 package footprint.

Upgrade Substitutes increase the rated voltage above 50V while maintaining all other electrical parameters. These parts provide enhanced voltage margin and are mechanically compatible with the 0805 footprint, though thickness may vary. Upgrade substitutes are suitable for applications where higher voltage rating provides design flexibility.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and surface mount MLCC mounting type.

Engineering Selection Recommendations

Direct Substitutes (50V Rating): Parts KGM21NR71H103JM, KGM21NR71H103JT, 0805B103J500CT, 0805J0500103JXT, C0805C103J5RAC7800, VJ0805Y103JXACW1BC, and VJ0805Y103JXAPW1BC are electrically and mechanically equivalent to the primary part. All maintain Active product status and ROHS3 compliance. Selection among these options depends on packaging format availability (Tape & Reel or Cut Tape) and thickness constraints within the PCB assembly process.

Upgrade Substitutes (Higher Voltage Rating): Parts KGM21NR72A103JT (100V) and KGM21AR72D103JU (200V) provide increased voltage margin while maintaining identical capacitance, tolerance, and temperature coefficient. The 100V variant (KGM21NR72A103JT) offers minimal thickness increase (0.039"). The 200V variant (KGM21AR72D103JU) exhibits increased thickness (0.057") and should be evaluated for PCB assembly clearance compatibility.

All substitute parts are ROHS3 compliant with MSL 1 rating, suitable for unlimited moisture exposure conditions.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A capacitor with higher voltage rating (100V or 200V) is electrically compatible with a 50V application. The capacitor will operate within its rated specifications. Verify PCB assembly clearance, as higher voltage ratings may result in increased component thickness.

Q: What is the difference between direct substitutes and upgrade substitutes? A: Direct substitutes maintain identical 50V voltage rating and are pin-for-pin compatible with no design modifications. Upgrade substitutes provide 100V or 200V ratings, offering enhanced voltage margin for applications requiring additional safety factor or future design flexibility.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, meeting the same environmental and regulatory standards as the primary part.

Q: Does component thickness affect PCB assembly? A: Component thickness may impact PCB assembly processes, particularly in high-density layouts or applications with height constraints. Verify thickness compatibility with your specific PCB design. Direct substitutes range from 0.035" to 0.051" thickness. Upgrade substitutes with 200V rating reach 0.057" maximum thickness.

Q: Can I interchange between different manufacturers? A: Yes. All substitute parts maintain identical electrical specifications (10000 pF, ±5%, X7R, -55°C ~ 125°C) and 0805 package footprint. Cross-manufacturer substitution is supported provided packaging format and thickness requirements are met.

Q: What packaging formats are available? A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) formats. Verify packaging availability with your component supplier based on procurement volume and assembly requirements.
