Substitute Part Grouping Explanation

Substitution for the BQ014D0102K is determined by the following critical parameters:

Primary Substitution Criteria:

Capacitance value: 1000 pF (exact match required)
Dielectric material: Polyester, Metallized (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial (exact match required)
Voltage rating: Minimum 63V DC (equal or higher acceptable)
Tolerance: ±10% or tighter (±5% acceptable as upgrade)
Operating temperature: -55°C minimum and 100°C minimum (equal or wider range acceptable)

Direct Equivalent: The MMK5102K63J01L4BULK from KEMET meets all primary criteria with identical electrical specifications and compatible physical dimensions, making it a direct replacement.

Upgrade Substitutes: Parts from Cornell Dubilier Electronics (CDE) series 168 and 185 offer enhanced specifications including higher voltage ratings (100V or 400V DC), tighter tolerance (±5%), and extended operating temperature range (-55°C to 125°C). These upgrades maintain full backward compatibility while providing improved performance margins.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Specifications): Select MMK5102K63J01L4BULK from KEMET. This part maintains identical electrical and thermal specifications while offering active product status and ROHS3 compliance. The minimal dimensional variation (7.20mm vs 7.50mm length) is within acceptable PCB layout tolerances for through-hole applications.

For Enhanced Performance (Upgraded Specifications): Cornell Dubilier Electronics 168 and 185 series parts provide superior specifications suitable for applications requiring improved reliability margins. The 100V DC rated parts (168102J100A-F, 185102J100RAA-F, 185102J100RAB-F, 168102K100A-F, 185102K100RAB-F) offer 37% higher voltage rating with tighter tolerance and extended temperature range. The 400V DC rated parts (168102J400A-F, 185102J400RAA-F, 185102J400RAB-F) are appropriate for high-voltage circuit applications.
