Substitute Part Grouping Explanation

Substitution eligibility for the 2225AC683MAT1A\SB is determined by the following critical parameters:

• Capacitance Value: Must remain 0.068 µF (no deviation permitted)
• Package / Case: Must be 2225 (5763 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R for thermal stability characteristics
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: May be equal to or greater than 1000V (1kV)
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain RoHS3 compliance and REACH Unaffected status

The identified substitute part 2225SC683KAT1A meets all mandatory parameters while providing an upgraded voltage rating of 1500V (1.5kV) and improved tolerance of ±10%.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225AC683MAT1A\SB and 2225SC683KAT1A are Active products with full regulatory compliance. The substitute part 2225SC683KAT1A provides identical capacitance and package specifications with the following advantages:

• Higher voltage rating (1500V vs 1000V) provides increased design margin in high-voltage applications
• Tighter tolerance (±10% vs ±20%) improves circuit performance predictability
• Identical physical dimensions and thermal characteristics ensure direct mechanical and electrical compatibility
• Both parts maintain MSL 1 rating, eliminating moisture sensitivity concerns

Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for any application designed for the main part and offers enhanced performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can 2225SC683KAT1A replace 2225AC683MAT1A\SB in all applications?

A: Yes, provided the circuit design permits the higher voltage rating and improved tolerance. The substitute part meets or exceeds all electrical and mechanical specifications of the main part.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2225 (5763 Metric) package with dimensions of 0.225" L x 0.250" W (5.72mm x 6.35mm) and maximum thickness of 0.100" (2.54mm). PCB footprints are identical.

Q: What is the difference in voltage rating between these parts?

A: The main part is rated at 1000V (1kV), while the substitute is rated at 1500V (1.5kV). The higher rating in the substitute part provides additional voltage margin without changing physical size or capacitance value.

Q: Does the tolerance difference affect circuit performance?

A: The substitute part features ±10% tolerance compared to ±20% for the main part. This tighter tolerance may improve circuit performance in applications sensitive to capacitance variation, but both parts are suitable for general-purpose applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 2225AC683MAT1A\SB and 2225SC683KAT1A are ROHS3 Compliant with REACH Unaffected status.

Q: What is the packaging difference?

A: The main part uses standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Both are surface-mount compatible with identical electrical and mechanical characteristics.
