SQCSVA300JAT1A Equivalent & Substitute Parts

Part Overview

The SQCSVA300JAT1A is a 30 pF ±5% 250V ceramic capacitor manufactured by KYOCERA AVX in 0603 (1608 Metric) surface mount package. This component is designed for RF, microwave, and high-frequency applications requiring high Q and low loss characteristics. The part is currently obsolete, making identification of compatible substitute components essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SQCSVA300JAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 30 pF (exact match required)
• Tolerance: ±5% (acceptable range for electrical equivalence)
• Voltage Rating: 250V (minimum requirement; higher ratings are acceptable)
• Package / Case: 0603 (1608 Metric) (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount, MLCC (assembly process compatibility)
• Operating Temperature Range: -55°C ~ 125°C (functional temperature envelope)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The substitute part 600S300JT250XT manufactured by American Technical Ceramics meets all critical substitution criteria. While the substitute features a C0G/NP0 temperature coefficient (superior stability compared to the Type A coefficient of the original part) and enhanced performance characteristics (Ultra Low ESR), these represent functional improvements rather than deviations from the substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

The 600S300JT250XT from American Technical Ceramics is a direct functional substitute for the obsolete SQCSVA300JAT1A. Both components meet identical electrical specifications for capacitance, tolerance, voltage rating, and operating temperature range. Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent handling and storage requirements.

The substitute part is currently in active production status, providing supply chain continuity and availability advantages over the obsolete original part. The marginal increase in maximum thickness (0.035" versus 0.030") is within typical PCB assembly tolerances for 0603 packages and does not present mechanical compatibility issues for standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 600S300JT250XT be used as a direct replacement for the SQCSVA300JAT1A in existing designs?

A: Yes. Both components share identical capacitance (30 pF), tolerance (±5%), voltage rating (250V), package (0603), and operating temperature range (-55°C ~ 125°C). The substitute is physically and electrically compatible with the original part's PCB footprint and assembly requirements.

Q: What is the difference between Type A and C0G/NP0 temperature coefficients?

A: Type A temperature coefficient exhibits greater capacitance variation across the operating temperature range compared to C0G/NP0. The substitute's C0G/NP0 coefficient provides superior temperature stability, which represents a functional improvement for RF and high-frequency applications.

Q: Does the thickness difference between the two parts affect assembly compatibility?

A: No. The substitute's maximum thickness of 0.035" (0.89mm) versus the original's 0.030" (0.76mm) remains within standard 0603 package specifications and does not impact surface mount assembly processes or PCB clearance requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the SQCSVA300JAT1A and 600S300JT250XT are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity level for both parts?

A: Both components carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.
