Substitute Part Grouping Explanation

Substitution for the 08053C683KAT4P is determined by the following critical parameters:

Mandatory Matching Parameters:

Capacitance: 0.068 µF (exact match required)
Temperature Coefficient: X7R (ensures stable capacitance across operating temperature range)
Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
Mounting Type: Surface Mount, MLCC (assembly compatibility)
Operating Temperature Range: -55°C to 125°C (functional equivalence)

Allowable Variation Parameters:

Voltage - Rated: 25V or higher (higher voltage ratings provide design margin and are functionally compatible)
Tolerance: ±10% or tighter (±5% tolerance is acceptable as it meets or exceeds the original specification)

Substitute parts are grouped into two categories: direct equivalents (matching voltage rating) and upgrades (higher voltage rating with same or better tolerance).

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating - 25V):

C0805C683K3RAC7800 (KEMET) is the primary direct equivalent. It matches all critical parameters including 25V voltage rating and ±10% tolerance. This part is in active production status with ROHS3 compliance and MSL 1 rating, making it suitable for new designs and production applications.

C0805C683J3RAC7800 (KEMET) provides improved tolerance (±5%) at the same 25V rating. This tighter tolerance specification is functionally compatible and offers enhanced capacitance accuracy for applications requiring stricter component specifications.

Upgrade Options (Higher Voltage Rating):

KGM21NR71H683KT (KYOCERA AVX) provides a 50V rated upgrade with matching ±10% tolerance. This part maintains the original manufacturer (KYOCERA AVX) and is in active production with 58879 pieces in stock, offering the highest availability among all substitutes.

KGM21NR71H683JT (KYOCERA AVX) provides a 50V rated upgrade with improved ±5% tolerance. This combines the original manufacturer with enhanced tolerance specifications.

C0805C683K5RAC7800 (KEMET) provides a 50V rated upgrade with ±10% tolerance and active production status.

C0805C683J5RAC7800 (KEMET) provides a 50V rated upgrade with improved ±5% tolerance.

C0805C683K1RAC7800 (KEMET) provides a 100V rated upgrade with ±10% tolerance for applications requiring maximum voltage margin.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 125°C operating temperature range. Selection should prioritize active production status parts for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V or 100V rated capacitor in place of the 25V rated 08053C683KAT4P?

A: Yes. Higher voltage ratings are functionally compatible in circuits designed for 25V operation. The capacitor will operate safely with additional voltage margin. Physical dimensions remain identical across all substitute parts in the 0805 package.

Q: What is the difference between ±10% and ±5% tolerance specifications?

A: Tolerance defines the allowable deviation from the nominal 0.068 µF capacitance value. ±10% allows 0.0612 µF to 0.0748 µF, while ±5% allows 0.0646 µF to 0.0714 µF. Both are acceptable substitutes; ±5% provides tighter capacitance accuracy for precision applications.

Q: Are all substitute parts compatible with existing PCB layouts?

A: Yes. All substitute parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.01mm x 1.25mm). Thickness varies slightly (0.037" to 0.043" maximum), but this does not affect PCB assembly compatibility.

Q: Why is the 08053C683KAT4P discontinued?

A: The part is discontinued at DiGi Electronics. Multiple active production equivalents from KYOCERA AVX and KEMET are available as direct replacements or upgrades.

Q: Which substitute part offers the best availability?

A: KGM21NR71H683KT (KYOCERA AVX) offers the highest inventory with 58879 pieces in stock. This part provides a 50V upgrade with ±10% tolerance matching the original specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory specifications of the original part.
