Key Parameters

Substitute Part Grouping Explanation

The CD45-B2GA101K-NKA qualifies as a direct substitute for the CD70-B2GA101KYNKA based on the following critical parameters:

• Identical capacitance value: 100 pF
• Identical tolerance: ±10%
• Identical voltage rating: 440VAC
• Identical temperature coefficient: B
• Identical safety ratings: X1, Y1
• Identical mounting type: Through Hole
• Identical package type: Radial, Disc
• Identical lead style: Formed Leads - Kinked
• Identical RoHS compliance: ROHS3 Compliant

Substitution is valid when these core electrical and mechanical parameters remain unchanged. Physical dimensions may vary within acceptable tolerances for board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CD70-B2GA101KYNKA and CD45-B2GA101K-NKA are active production parts from TDK Corporation with ROHS3 compliance. Selection between these parts should be based on:

• Operating temperature requirements: The CD70-B2GA101KYNKA supports -25°C to 105°C, while the CD45-B2GA101K-NKA supports -25°C to 85°C. Applications requiring operation above 85°C must use the CD70-B2GA101KYNKA.
• Physical space constraints: The CD45-B2GA101K-NKA has a smaller diameter (6.50mm vs 7.00mm) and height (10.50mm vs 11.00mm), making it suitable for compact board layouts where the CD70-B2GA101KYNKA cannot fit.
• Inventory availability: The CD45-B2GA101K-NKA has higher stock availability (7093 units vs 1056 units).

Both parts maintain identical electrical performance, safety ratings, and lead spacing for PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CD45-B2GA101K-NKA replace the CD70-B2GA101KYNKA in all applications?

A: The CD45-B2GA101K-NKA can replace the CD70-B2GA101KYNKA in applications where the operating temperature does not exceed 85°C. If your application requires operation above 85°C, the CD70-B2GA101KYNKA must be used.

Q: Are the lead spacings compatible between these two parts?

A: Yes. Both parts have identical lead spacing of 0.394" (10.00mm), ensuring PCB footprint compatibility.

Q: What is the difference in physical size between these capacitors?

A: The CD45-B2GA101K-NKA is slightly smaller with a diameter of 6.50mm and height of 10.50mm, compared to the CD70-B2GA101KYNKA at 7.00mm diameter and 11.00mm height. Both fit standard radial disc capacitor footprints.

Q: Do both parts meet the same safety and compliance standards?

A: Yes. Both parts carry X1, Y1 safety ratings, are ROHS3 compliant, and are classified under ECCN EAR99 with identical HTSUS codes.

Q: Which part should I select for new designs?

A: Selection depends on your specific operating temperature range and available board space. For applications operating above 85°C, use the CD70-B2GA101KYNKA. For space-constrained designs operating at or below 85°C, the CD45-B2GA101K-NKA is suitable.
