106SML050MD5 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The 106SML050MD5 is a 10 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SML series. This surface mount device is designed for general purpose applications requiring stable capacitance performance across extended operating temperatures from -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. The part is currently in active product status with RoHS3 compliance and REACH unaffected classification.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or inventory depletion. The following equivalent components maintain the critical electrical and mechanical parameters required for direct functional replacement in surface mount applications.

Engineering Selection Recommendations

Primary Selection: VE-100M1HTR-0505S (SURGE)

The VE-100M1HTR-0505S is the preferred substitute for the 106SML050MD5. This part maintains active product status, ensuring continued availability and manufacturer support. It meets all electrical and mechanical equivalence criteria with identical capacitance, voltage rating, temperature range, and lifetime specifications. The surface mount package and land size are fully compatible with existing PCB designs. RoHS3 compliance and REACH unaffected status satisfy regulatory requirements. Cut Tape packaging provides flexibility for production environments.

Secondary Selection: UWR1H100MCL1GB (Nichicon)

The UWR1H100MCL1GB provides full electrical and mechanical equivalence to the 106SML050MD5 across all critical parameters. However, this part carries obsolete product status, indicating discontinued manufacturing and potential future supply unavailability. Selection of this substitute should be limited to applications where existing inventory is available and long-term supply is not a requirement. Tape & Reel packaging is suitable for automated assembly processes. All compliance certifications match the primary part.

Ripple Current Consideration:

The 106SML050MD5 specifies 41 mA ripple current at 120 Hz. The VE-100M1HTR-0505S provides 35 mA and the UWR1H100MCL1GB provides 33 mA at the same frequency. These values remain within acceptable operating parameters for general purpose applications. Applications requiring maximum ripple current handling should prioritize the primary part or confirm ripple current specifications against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the VE-100M1HTR-0505S be used as a direct replacement for the 106SML050MD5 without PCB modifications?

A: Yes. The VE-100M1HTR-0505S maintains identical mechanical dimensions, surface mount land size, and electrical specifications. No PCB layout changes are required for direct substitution.

Q: Why is the UWR1H100MCL1GB listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production of this part. While existing inventory may be available, future supply cannot be guaranteed. This classification affects long-term component sourcing strategy.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging (UWR1H100MCL1GB) is supplied on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging (VE-100M1HTR-0505S) is supplied as individual tape segments, appropriate for lower-volume or mixed-component production runs.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 106SML050MD5, UWR1H100MCL1GB, and VE-100M1HTR-0505S are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. Components with this rating can be stored indefinitely under normal conditions without special humidity control or pre-reflow baking procedures.

Q: Can I use these capacitors in high-ripple-current applications?

A: The ripple current ratings differ among the three parts: 106SML050MD5 (41 mA), VE-100M1HTR-0505S (35 mA), and UWR1H100MCL1GB (33 mA) at 120 Hz. Verify that the selected substitute meets the specific ripple current requirements of your application circuit.

Q: Are there any temperature derating considerations?

A: All three parts operate across the identical temperature range of -40°C to 85°C with 2000-hour lifetime at 85°C. No derating adjustments are required when substituting between these parts within this temperature envelope.
