Substitute Part Grouping Explanation

Substitution eligibility for the CD45-B2GA101K-GKA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 100 pF (exact match required)
• Voltage Rating: 440VAC (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: B (exact match required)
• Safety Ratings: X1, Y1 (exact match required)
• Mounting Configuration: Through Hole, Radial, Disc package with kinked formed leads
• Regulatory Compliance: ROHS3 Compliant

The identified substitute part CD45-B2GA101K-NKA maintains identical electrical specifications and mechanical form factor, differing only in packaging designation and inventory source within the same TDK CD series product line.

Parameter Comparison

Engineering Selection Recommendations

Both CD45-B2GA101K-GKA and CD45-B2GA101K-NKA are active production parts from TDK Corporation with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and procurement source. The CD45-B2GA101K-NKA offers higher current inventory (7093 units) compared to the GKA variant (1032 units), providing supply chain flexibility. Both parts maintain ROHS3 compliance and are suitable for safety-critical applications requiring X1, Y1 ratings in 440VAC circuits.

Frequently Asked Questions (FAQ)

Q: Can CD45-B2GA101K-NKA be used as a direct replacement for CD45-B2GA101K-GKA?

A: Yes. Both parts are electrically and mechanically identical, with matching capacitance (100 pF), voltage rating (440VAC), tolerance (±10%), temperature coefficient (B), safety ratings (X1, Y1), and physical dimensions. The difference lies only in packaging designation and inventory source.

Q: What determines substitution eligibility for this capacitor?

A: Substitution requires exact equivalence in capacitance value, voltage rating, tolerance, temperature coefficient, safety ratings, and physical form factor. Any deviation in these parameters disqualifies a part from substitution.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8532.23.0060) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

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 through-hole mounting configuration ensure direct PCB compatibility without layout modifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -25°C to 85°C, with temperature coefficient B providing stable capacitance performance within this range.
