Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS45-B2GA331K-GKA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Voltage rating: 440VAC
• Temperature coefficient: B
• Operating temperature range: -25°C ~ 125°C
• Safety ratings: X1, Y2
• Mounting configuration: Through Hole, Radial Disc
• Lead spacing: 0.295" (7.50mm)
• RoHS compliance: ROHS3

Parts meeting all these criteria are classified as direct equivalents and may be used interchangeably in circuit designs without modification to PCB layouts or electrical schematics.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA331K-NKA be used as a direct replacement for CS45-B2GA331K-GKA?

A: Yes. Both parts are identical in capacitance (330 pF), voltage rating (440VAC), tolerance (±10%), temperature coefficient (B), operating temperature range (-25°C ~ 125°C), safety ratings (X1, Y2), and mechanical configuration (Through Hole, Radial Disc with 0.295" lead spacing). Direct substitution is possible without PCB or schematic modifications.

Q: Are there any differences in lead style or packaging between these parts?

A: No. Both parts feature formed leads with kinked style and are supplied in bulk packaging. The physical dimensions, lead spacing, and disc diameter are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CS45-B2GA331K-GKA and CS45-B2GA331K-NKA are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.23.0060) classifications.

Q: What determines substitution eligibility for this capacitor?

A: Substitution is determined by matching capacitance value, tolerance, voltage rating, temperature coefficient, operating temperature range, safety ratings, mounting type, package configuration, and lead spacing. All these parameters must be identical for parts to be considered direct equivalents.
