0603J0630331FCT Equivalent & Substitute Parts

Part Overview

The 0603J0630331FCT is a 330 pF ceramic capacitor manufactured by Knowles Syfer, rated at 63V with C0G/NP0 temperature coefficient and ±1% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 0603 package format is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when design requirements allow for higher voltage ratings or alternative manufacturers while maintaining identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J0630331FCT is determined by the following criteria:

Required Matching Parameters:

• Capacitance: 330 pF (exact match)
• Tolerance: ±1% (exact match)
• Temperature Coefficient: C0G or NP0 (equivalent specifications)
• Package / Case: 0603 (1608 Metric) (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)

Allowable Variation:

• Voltage Rating: May be equal to or greater than 63V (uprating permitted)
• Manufacturer: Alternative qualified manufacturers acceptable
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats interchangeable in production environments

The identified substitute parts meet all required matching parameters and represent voltage uprating options, which are electrically compatible with circuits designed for the original 63V specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the 0603J0630331FCT based on the following criteria:

0603J1000331FCT (Knowles Syfer): This part maintains manufacturer continuity with the original specification while providing a 100V voltage rating. The uprated voltage specification is compatible with 63V circuit designs and offers enhanced margin for transient voltage conditions. ROHS3 compliance and MSL 1 rating match the original part exactly.

KGM15ACG2A331FT (KYOCERA AVX): This part represents a cross-manufacturer substitute from KYOCERA AVX, a qualified alternative source. The 100V voltage rating and identical capacitance, tolerance, and temperature coefficient specifications ensure functional compatibility. ROHS3 compliance and MSL 1 rating are maintained. The KGM series designation indicates C0G dielectric material consistency.

Both substitute parts are active production items with established supply availability and full compliance certifications. Selection between substitutes may be determined by supply chain requirements, packaging format preferences (Tape & Reel versus Cut Tape), or inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 0603J1000331FCT or KGM15ACG2A331FT be used in place of 0603J0630331FCT?

A: Yes. Both substitute parts maintain identical capacitance (330 pF), tolerance (±1%), temperature coefficient (C0G/NP0), package format (0603), and operating temperature range (-55°C to 125°C). The higher voltage ratings (100V) are compatible with circuits designed for 63V operation.

Q: What is the significance of the voltage rating difference?

A: The substitute parts are rated for 100V, compared to the original 63V rating. In circuit applications, this represents a voltage uprating and is electrically compatible. The higher voltage rating does not affect capacitance value or temperature stability. Circuits designed for 63V operation will function correctly with 100V-rated capacitors.

Q: Are there physical dimension differences between these parts?

A: All three parts conform to the 0603 (1608 Metric) package standard. The KGM15ACG2A331FT has a maximum thickness of 0.035" (0.90mm) compared to 0.031" (0.80mm) for the Knowles Syfer parts. This thickness variation remains within standard 0603 package tolerances and does not affect PCB assembly compatibility.

Q: What packaging formats are available?

A: The 0603J0630331FCT and 0603J1000331FCT are supplied in Tape & Reel (TR) format. The KGM15ACG2A331FT is available in Cut Tape (CT) and Digi-Reel® format. Both formats are suitable for automated assembly processes.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity level rating, meeting current environmental and reliability standards.
