Substitute Part Grouping Explanation

Substitution for the 08053C103KA72A is determined by the following criteria:

Mandatory Parameters (Must Match):

Capacitance: 10000 pF
Temperature Coefficient: X7R
Package / Case: 0805 (2012 Metric)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C to 125°C
Moisture Sensitivity Level: MSL 1

Flexible Parameters (May Vary):

Voltage Rating: Substitute parts rated at 50V, 100V, or 250V are acceptable as they exceed the original 25V specification
Tolerance: ±5% or ±10% are acceptable
Product Status: Active status preferred over obsolete
RoHS Compliance: ROHS3 compliant variants are preferred

Substitute parts are grouped by voltage rating, as this is the primary differentiator among available alternatives while maintaining all other critical electrical and mechanical specifications.

Engineering Selection Recommendations

For RoHS3 Compliance and Active Product Status:

The 50V rated variants 08055C103KAQ2A, 08055C103KAT2M, and 08055C103KAT2P are recommended as primary substitutes. These parts maintain identical capacitance, tolerance, temperature coefficient, and package specifications while offering active product status and ROHS3 compliance. The 50V rating provides adequate voltage margin for applications originally designed for 25V operation.

The 100V rated variant 08051C103KAT2P offers higher voltage headroom and ROHS3 compliance for applications requiring additional voltage margin.

The 250V rated variant 0805PC103KAT2A provides maximum voltage rating with ROHS3 compliance and is suitable for applications with elevated voltage requirements or future design flexibility.

For Tolerance Considerations:

The 08055C103JAT2M variant offers ±5% tolerance with 50V rating and ROHS3 compliance, providing tighter capacitance tolerance than the original ±10% specification.

For Non-Compliance Scenarios:

If RoHS compliance is not a requirement, the 50V rated variants 08055C103KA12A, 08055C103KA72A, 08055C103KAJ2A, and 08055C103KAJ4A remain available with active product status.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 25V original part?

A: Yes. The 50V rated substitute parts are electrically compatible. Higher voltage ratings provide additional safety margin and do not degrade performance in circuits designed for lower voltages. All 50V variants maintain the same capacitance, tolerance, temperature coefficient, and package specifications.

Q: What is the difference between the multiple 50V variants?

A: The 50V variants differ in packaging format (Tape & Reel vs. standard), RoHS compliance status, and REACH status. Electrically and mechanically, they are equivalent. Selection depends on procurement requirements and compliance certifications needed for your application.

Q: Is the ±5% tolerance variant compatible with designs specified for ±10%?

A: Yes. The 08055C103JAT2M with ±5% tolerance is a direct substitute and provides tighter capacitance tolerance than the original specification, making it suitable for applications requiring improved accuracy.

Q: What is the physical size difference between the original and substitute parts?

A: All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.01mm x 1.25mm). The 250V variant has a maximum thickness of 0.051" (1.30mm) compared to 0.037" (0.94mm) for lower voltage ratings. Verify PCB clearance for the 250V variant in space-constrained layouts.

Q: Why is the original part obsolete?

A: The 08053C103KA72A is classified as obsolete. Multiple active alternatives with improved compliance certifications are available to support design continuity and procurement requirements.

Q: Which substitute should I choose for new designs?

A: For new designs, select from the ROHS3 compliant variants: 08055C103KAQ2A, 08055C103KAT2M, 08055C103KAT2P (50V), 08051C103KAT2P (100V), or 0805PC103KAT2A (250V). These parts offer active product status and compliance with current environmental regulations.
