Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

EEU-EB2W100, EEU-EE2W100, EEU-EE2W100U (Panasonic): Preferred for continuity with original manufacturer. All ROHS3 compliant and REACH unaffected.
450BXC10MEFC12.5X16, 450BXC10MEFC12.5X20, 450LLE10MEFC12.5X20 (Rubycon): Extended lifetime options with ROHS3 compliance.
106CKE450M (Cornell Dubilier / Illinois Capacitor): Alternative manufacturer with ROHS3 compliance.
UCS2W100MHD (Nichicon): Active status with ROHS3 compliance.

Obsolete Status Parts (Replacement Only):

EKXG451ELL100MK20S (Chemi-Con): Obsolete status; use only for direct replacement in existing designs.
UCA2W100MHD (Nichicon): Obsolete status; use only for direct replacement in existing designs.

All listed parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component deployment.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ECA-2WHG100 with any of the listed parts? A: Yes, all listed parts are electrically and mechanically interchangeable. They share identical capacitance (10 µF), tolerance (±20%), voltage rating (450 V), lead spacing (5.00mm), and radial can package format. Height variations within the specified range (0.709" to 0.866") are compatible with standard through-hole PCB layouts.

Q: What is the difference between Active and Obsolete status parts? A: Active status parts are currently manufactured and available for new designs. Obsolete status parts are no longer in production but may be available from inventory. Use obsolete parts only for direct replacement in existing equipment or when Active alternatives are unavailable.

Q: Does extended lifetime affect electrical performance? A: No. Extended lifetime ratings (5000 Hrs, 8000 Hrs, 10000 Hrs, 12000 Hrs, 20000 Hrs) indicate longer operational durability at 105°C but do not change the core electrical specifications. Capacitance, voltage rating, and tolerance remain identical across all substitute parts.

Q: Are there height restrictions for PCB mounting? A: Height variations range from 0.709" (18.00mm) to 0.866" (22.00mm). Verify PCB clearance specifications before selecting parts with different heights. The 450BXC10MEFC12.5X16 has the smallest height (0.709"), while most alternatives match the original 0.866" specification.

Q: Which substitute offers the best ripple current performance? A: The EKXG451ELL100MK20S provides the highest ripple current at 180 mA @ 120 Hz. However, this part is obsolete. Among Active status parts, the EEU-EE2W100 and 450LLE10MEFC12.5X20 offer 171.5 mA and 135 mA respectively at 120 Hz.

Q: Are all parts ROHS3 compliant? A: Yes, all listed parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and deployment.
