UWD0J101MCL1GS Equivalent & Substitute Parts

Part Overview

The UWD0J101MCL1GS is a 100 µF, 6.3 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Nichicon. This component operates across -55°C to 105°C with a rated lifetime of 2000 hours at 105°C and is designed for general purpose applications. The part is currently active in production with 1815 units in stock.

Equivalent and substitute parts are identified based on matching electrical characteristics (capacitance, voltage rating, ripple current capability, impedance) and mechanical compatibility (package type, mounting footprint, physical dimensions). Alternative parts may be selected when the primary part is unavailable, when design requirements permit higher voltage ratings, or when automotive-grade certifications are required.

Substitute Part Grouping Explanation

Substitution logic for the UWD0J101MCL1GS is based on the following criteria:

Upgrade Substitutes maintain identical capacitance (100 µF), tolerance (±20%), and mechanical compatibility while offering enhanced voltage ratings or automotive-grade certifications. These parts are direct functional upgrades with equal or superior electrical performance.

Similar Substitutes share the same capacitance and voltage rating but differ in physical dimensions, ripple current capability, or impedance characteristics. These require PCB footprint verification before implementation.

Parametric Equivalents match all critical electrical parameters and physical dimensions but may differ in series designation or minor performance characteristics.

Key parameters determining substitutability:

Capacitance value (100 µF fixed)
Voltage rating (6.3 V minimum; higher ratings acceptable)
Package type (Radial, Can - SMD required)
Case diameter (6.30mm preferred; 5.00mm acceptable with footprint verification)
Land size compatibility (6.60mm x 6.60mm or 5.30mm x 5.30mm)
Ripple current capability (minimum 115 mA @ 120 Hz)
Operating temperature range (-55°C ~ 105°C minimum)

Engineering Selection Recommendations

Direct Upgrade Path (Same Footprint, Enhanced Compliance)

UUD0J101MCL1GS is the primary upgrade substitute. It maintains identical electrical specifications (100 µF, 6.3 V, 2000 Hrs @ 105°C) and mechanical compatibility (6.30mm diameter, 6.60mm x 6.60mm land size) while adding AEC-Q200 automotive qualification. Height increases from 5.80mm to 6.10mm; verify clearance in confined spaces.

Higher Voltage Substitutes (Same Footprint)

UUD1A101MCL1GS (10 V) and UUD1C101MCL1GS (16 V) provide voltage margin for circuits operating near the 6.3 V rating limit. Both maintain identical capacitance, ripple current, impedance, and footprint. UWD1A101MCL1GS and UWD1C101MCL1GS offer equivalent performance in the general purpose series without automotive certification.

Reduced Footprint Alternatives (Smaller Case)

UCD0J101MCL6GS and UCL0J101MCL6GS use 5.00mm case diameter with 5.30mm x 5.30mm land size. These require PCB redesign but enable space optimization. UCD0J101MCL6GS includes AEC-Q200 certification. Both exhibit reduced ripple current capability (80–120 mA @ 120 Hz versus 115 mA) and higher impedance; verify circuit performance before substitution.

Avoid in New Designs

UWF0J101MCL1GB is obsolete with reduced lifetime (1000 Hrs @ 105°C) and significantly lower ripple current (57.5 mA @ 120 Hz). UWG0J101MCL1GB operates at 1000 Hrs @ 105°C, half the rated lifetime of the primary part.

Parametric Equivalent

UCL0J101MCL1GS matches all critical parameters with superior ripple current (150 mA @ 120 Hz) and lower impedance (260 mOhms). Identical footprint and dimensions enable direct substitution.

Frequently Asked Questions (FAQ)

Q: Can UUD0J101MCL1GS replace UWD0J101MCL1GS directly?

A: Yes. Both parts share 100 µF capacitance, 6.3 V rating, 2000 Hrs @ 105°C lifetime, and identical ripple current specifications. The UUD series adds AEC-Q200 automotive qualification. Height increases from 5.80mm to 6.10mm; confirm clearance in your PCB layout.

Q: What is the difference between UUD1A101MCL1GS (10 V) and the original 6.3 V part?

A: The 10 V variant provides higher voltage margin for the same capacitance and footprint. All other electrical parameters (ripple current, impedance, lifetime) remain identical. Use when circuit voltage may exceed 6.3 V or when design margin is required.

Q: Can I use UCD0J101MCL6GS in place of UWD0J101MCL1GS?

A: Electrical substitution is possible (100 µF, 6.3 V, 2000 Hrs @ 105°C), but mechanical redesign is required. The UCD part uses a smaller 5.00mm case diameter with 5.30mm x 5.30mm land size versus 6.30mm and 6.60mm x 6.60mm. Ripple current is reduced to 80 mA @ 120 Hz. Verify circuit performance and PCB layout compatibility.

Q: Why is UWF0J101MCL1GB listed as obsolete?

A: The UWF series has been discontinued. Additionally, it offers only 1000 Hrs @ 105°C lifetime (half the UWD0J101MCL1GS rating) and 57.5 mA ripple current capacity, making it unsuitable for new designs requiring 2000 Hrs reliability.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard for passive components. Parts bearing this rating (UUD series, UCD0J101MCL6GS, UWG0J101MCL1GB) meet automotive reliability and environmental stress testing requirements. Use AEC-Q200 parts in automotive applications or when enhanced reliability is specified.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance. Moisture Sensitivity Level is 1 (Unlimited) for most parts, indicating no special moisture handling is required during assembly.

Q: Which substitute offers the best electrical performance?

A: UCL0J101MCL1GS provides superior ripple current (150 mA @ 120 Hz) and lowest impedance (260 mOhms) while maintaining identical 100 µF, 6.3 V, 2000 Hrs @ 105°C specifications and footprint. It is the parametric equivalent with enhanced performance characteristics.
