Substitute Part Grouping Explanation

The CD45-B2GA151K-NKA is classified as a parametric equivalent to the CD45-B2GA151K-GKA. Substitution is valid based on the following criteria:

• Identical capacitance value: 150 pF
• Identical tolerance: ±10%
• Identical voltage rating: 440VAC
• Identical temperature coefficient: B
• Identical operating temperature range: -25°C to 85°C
• Identical safety ratings: X1, Y1
• Identical mounting type: Through Hole
• Identical package configuration: Radial, Disc
• Identical physical dimensions and lead spacing
• Identical lead style: Formed Leads - Kinked
• Both parts are ROHS3 compliant
• Both parts maintain MSL rating of 1 (Unlimited)

The substitution is based strictly on electrical performance and mechanical compatibility. Both parts are manufactured by TDK Corporation within the same CD series.

Parameter Comparison

Both parts meet identical electrical specifications and safety certifications (X1, Y1 ratings) required for safety-critical applications. No performance differentiation exists between these parts for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can CD45-B2GA151K-NKA be used as a direct replacement for CD45-B2GA151K-GKA?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance, voltage rating, temperature coefficient, operating temperature range, safety ratings, and physical dimensions. Direct substitution is valid without circuit redesign.

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

A: No. Both parts are ROHS3 compliant and carry identical MSL ratings of 1 (Unlimited). Both maintain X1, Y1 safety certifications required for high-voltage applications.

Q: What determines the substitution validity between these two parts?

A: Substitution is valid based on matching electrical parameters (150 pF capacitance, ±10% tolerance, 440VAC rating, B temperature coefficient) and mechanical specifications (Through Hole mounting, Radial Disc package, identical lead spacing and dimensions).

Q: Are there any lead time or availability considerations?

A: The CD45-B2GA151K-NKA has higher current inventory availability. Selection should consider project lead time requirements and supply chain planning.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical lead spacing (0.394" / 10.00mm), lead style (Formed Leads - Kinked), and physical dimensions ensure interchangeable PCB placement and soldering without modification to board layouts or assembly procedures.
