Substitute Part Grouping Explanation

Substitution for the UCA2G100MPD is determined by the following critical parameters: capacitance (10 µF), voltage rating (400 V minimum), tolerance (±20%), polarization (polar), package type (radial can), mounting type (through hole), and lead spacing (5.00 mm). Parts are grouped into three categories based on their relationship to the original specification:

Direct Equivalents maintain identical electrical and mechanical specifications, differing only in packaging format or minor product status changes.

Manufacturer Recommended Substitutes offer equivalent performance with enhanced specifications (higher ripple current capability or extended operating temperature range) while maintaining the same footprint and electrical characteristics.

Upgrade Options provide higher voltage ratings or extended lifetime ratings, suitable for applications requiring improved performance margins or reliability enhancements.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): UCA2G100MPD1TD is the direct equivalent in cut tape packaging. UCS2G100MPD from Nichicon is an active alternative with extended operating temperature range (-40°C minimum). Both maintain 400 V rating and 10 µF capacitance with ROHS3 compliance.

For Enhanced Performance: UCY2W100MPD and UCYW6100MPD offer higher voltage ratings (450 V and 420 V respectively) with extended lifetime (12,000 hours) and wider operating temperature range (-40°C to 105°C). These are suitable for applications requiring improved reliability margins.

For Multi-Source Availability: 106KFM400M (Cornell Dubilier), 400BXC10MEFC10X20 (Rubycon), EEU-ED2G100 (Panasonic), and ESU106M400AH4AA (KEMET) provide equivalent 10 µF, 400 V specifications with active product status and ROHS3 compliance. All maintain through-hole radial can package with 5.00 mm lead spacing.

For Higher Voltage Applications: 420BXC10MEFC10X20 and 450BXC10MEFC10X20 from Rubycon provide 420 V and 450 V ratings respectively, maintaining 10 µF capacitance and 10,000-hour lifetime at 105°C.

Frequently Asked Questions (FAQ)

Q: Can UCA2G100MPD be replaced with a 400 V rated capacitor from a different manufacturer? A: Yes. Any capacitor meeting the following criteria is electrically compatible: 10 µF capacitance, 400 V minimum voltage rating, ±20% tolerance, polar configuration, radial can package, through-hole mounting, and 5.00 mm lead spacing. Candidates include 106KFM400M, 400BXC10MEFC10X20, EEU-ED2G100, and ESU106M400AH4AA.

Q: What is the difference between direct equivalents and upgrade options? A: Direct equivalents (UCA2G100MPD1TD, UCS2G100MPD) maintain the original 400 V specification. Upgrade options (UCY2W100MPD at 450 V, UCYW6100MPD at 420 V) provide higher voltage ratings and extended lifetime, suitable for applications requiring additional performance margin.

Q: Are there height restrictions when substituting this capacitor? A: The original UCA2G100MPD has a maximum seated height of 0.846" (21.50 mm). Substitutes from Rubycon (400BXC10MEFC10X20, 420BXC10MEFC10X20, 450BXC10MEFC10X20) and Cornell Dubilier (106KFM400M) have maximum heights of 0.866" (22.00 mm). EEU-ED2G100 from Panasonic is shorter at 0.787" (20.00 mm). Verify PCB layout clearance before selection.

Q: Which substitutes are recommended for new designs? A: UCS2G100MPD, UCY2W100MPD, UCYW6100MPD, 106KFM400M, 400BXC10MEFC10X20, EEU-ED2G100, ESU106M400AH4AA, 420BXC10MEFC10X20, and 450BXC10MEFC10X20 all have active product status and are suitable for new designs.

Q: Does packaging format affect electrical performance? A: No. UCA2G100MPD (bulk) and UCA2G100MPD1TD (cut tape) are electrically identical. Packaging format affects only procurement and handling logistics, not component performance.

Q: What compliance certifications apply to these substitutes? A: All listed substitutes are ROHS3 compliant. REACH status varies: most are REACH Unaffected; UCY2W100MPD and UCYW6100MPD are REACH Affected. Verify compliance requirements for your application before final selection.
