Substitute Part Grouping Explanation

Substitution eligibility for the CS45-B2GA151K-GKA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 150 pF
• Tolerance: ±10%
• Voltage rating: 440VAC
• Temperature coefficient: B
• Operating temperature range: -25°C ~ 125°C
• Safety ratings: X1, Y2
• Mounting type: Through Hole
• Package configuration: Radial, Disc
• Lead spacing: 0.295" (7.50mm)
• RoHS compliance: ROHS3 Compliant

The identified substitute part maintains complete electrical and mechanical equivalence. The only difference is packaging format: the main part is supplied in bulk packaging, while the substitute is supplied in Tape & Box (TB) format. Both parts are manufactured by TDK Corporation within the CS45 series and carry identical product status and certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CS45-B2GA151K-GKA and CS45-B2GA151K-NKA are active production parts manufactured by TDK Corporation with identical electrical specifications and safety certifications. Selection between these parts is determined by packaging requirements and inventory availability:

• CS45-B2GA151K-GKA: Select for applications requiring bulk packaging format with current inventory of 1115 units.
• CS45-B2GA151K-NKA: Select for applications requiring Tape & Box (TB) packaging format with current inventory of 1719 units.

Both parts meet ROHS3 compliance requirements and carry X1, Y2 safety ratings suitable for safety-critical applications. No functional or performance differences exist between these parts.

Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA151K-NKA be used as a direct replacement for CS45-B2GA151K-GKA?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Box). PCB assembly and circuit performance are unaffected by this packaging difference.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status and X1, Y2 safety ratings. No additional testing or qualification is required when substituting between these parts.

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling, storage, and automated assembly processes. Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Box (TB) packaging is optimized for automated pick-and-place assembly equipment. Electrical performance and reliability are not affected by packaging format.

Q: Can these parts be used interchangeably in high-voltage safety applications?

A: Yes. Both parts carry identical X1, Y2 safety ratings and 440VAC voltage rating. They are fully interchangeable in safety-critical applications without re-qualification.

Q: What determines whether a part can substitute for the CS45-B2GA151K-GKA?

A: Substitution requires exact equivalence in capacitance (150 pF), tolerance (±10%), voltage rating (440VAC), temperature coefficient (B), operating temperature range (-25°C ~ 125°C), safety ratings (X1, Y2), mounting type (Through Hole), package configuration (Radial, Disc), and lead spacing (0.295" / 7.50mm). Packaging format is not a substitution barrier.
