UCS2C101MHD6 Equivalent & Substitute Parts

Part Overview

The UCS2C101MHD6 is a 100 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 10000 hours at 105°C. Substitute parts are necessary when higher voltage ratings, extended operational lifetime, or specific compliance requirements are required for circuit redesign or component availability optimization.

Substitute Part Grouping Explanation

Substitution of the UCS2C101MHD6 is determined by the following criteria:

Electrical Compatibility: All substitute parts maintain identical capacitance (100 µF) and tolerance (±20%). Voltage rating substitution follows the principle that higher voltage-rated capacitors can replace lower voltage-rated units in the same physical package, provided mechanical fit and thermal characteristics remain compatible.

Mechanical Compatibility: All substitute parts share identical lead spacing (7.50mm), case diameter (16.00mm), and maximum seated height (21.50mm), ensuring direct through-hole mounting compatibility on existing PCB layouts.

Thermal and Lifetime Characteristics: Substitute parts are grouped by rated lifetime at 105°C (10000 hours or 12000 hours) and ripple current specifications at standard frequencies (120 Hz and 100 kHz).

Compliance and Certification: Substitute parts are evaluated based on RoHS status, REACH compliance, and application-specific certifications such as AEC-Q200 for automotive use.

Engineering Selection Recommendations

UCS2D101MHD (Nichicon, 200 V): Direct upgrade within the same UCS series. Maintains identical thermal lifetime (10000 hours at 105°C) and ripple current specifications. Voltage rating increased from 160 V to 200 V. REACH Unaffected status. Suitable for applications requiring higher voltage margin without extended lifetime requirements.

UCY2D101MHD3 (Nichicon, 200 V): Series upgrade from UCS to UCY with extended lifetime (12000 hours at 105°C). Voltage rating 200 V. REACH Affected status. Appropriate for designs requiring improved thermal endurance and compliance with REACH regulations.

UCY2E101MHD (Nichicon, 250 V): Series upgrade from UCS to UCY with extended lifetime (12000 hours at 105°C). Voltage rating increased to 250 V. Ripple current specifications marginally increased (715 mA @ 120 Hz, 1.43 A @ 100 kHz). REACH Affected status. Suitable for high-voltage applications with extended operational lifetime requirements.

EKXJ251ELL101ML20S (Chemi-Con, 250 V): Cross-manufacturer substitute from Chemi-Con KXJ series. Voltage rating 250 V with 10000-hour lifetime at 105°C. AEC-Q200 automotive qualification. REACH Unaffected status. Ripple current at 120 Hz reduced to 635 mA. Appropriate for automotive applications requiring AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can UCS2D101MHD replace UCS2C101MHD6 directly? A: Yes. Both parts share identical capacitance (100 µF), tolerance (±20%), lead spacing (7.50mm), case diameter (16.00mm), and maximum height (21.50mm). The voltage rating increases from 160 V to 200 V, which is a direct upgrade compatible with existing PCB layouts.

Q: What is the difference between UCS and UCY series? A: The UCY series provides extended lifetime (12000 hours at 105°C) compared to the UCS series (10000 hours at 105°C). Both series maintain identical physical dimensions and mounting characteristics.

Q: Is EKXJ251ELL101ML20S suitable for non-automotive applications? A: Yes. The EKXJ251ELL101ML20S meets ROHS3 compliance and shares identical physical dimensions with the main part. The AEC-Q200 automotive qualification does not restrict use in general purpose applications. However, ripple current at 120 Hz is specified at 635 mA, which is lower than the main part (710 mA).

Q: What does REACH Affected status mean? A: REACH Affected indicates the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This status requires compliance verification for applications in regulated markets. REACH Unaffected parts are not subject to these restrictions.

Q: Can a 250 V rated capacitor replace a 160 V rated capacitor? A: Yes. Higher voltage-rated capacitors can replace lower voltage-rated units in the same physical package. The 250 V rating provides additional voltage margin and is electrically compatible with circuits designed for 160 V operation.
