226SML016MD4 Equivalent & Substitute Parts

Part Overview

The 226SML016MD4 is a 22 µF, 16 V aluminum electrolytic capacitor in surface mount radial can packaging, manufactured by Cornell Dubilier / Illinois Capacitor. This component is rated for general purpose applications with an operating temperature range of -40°C to 85°C and a rated lifetime of 2000 hours at 85°C. The part is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts may be necessary due to supply chain constraints, inventory availability, or specific packaging requirements while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution criteria are based strictly on the following electrical and mechanical parameters: capacitance (22 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-40°C to 85°C), lifetime rating (2000 Hrs @ 85°C), polarization (polar), package type (radial can SMD), physical dimensions (0.157" diameter, 0.217" maximum height), and surface mount land size (0.169" L x 0.169" W). All substitute parts listed maintain these core electrical specifications and mechanical footprint compatibility.

The identified substitute parts are:

• UWR1C220MCL1GB (Nichicon, UWR series)
• VE-220M1CTR-0405S (SURGE, VE series)

Both parts share identical capacitance, voltage, tolerance, operating temperature range, lifetime rating, polarization, package designation, physical dimensions, and surface mount compatibility. Variations in ripple current ratings and ESR specifications do not disqualify these parts from substitution as they remain within acceptable performance margins for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

226SML016MD4 (Cornell Dubilier/Illinois Capacitor - Active Status): This is the primary specification part. It is in active production with bulk packaging availability and 998 units in current stock. ROHS3 compliance and MSL 1 rating support use in moisture-sensitive environments. Select this part when supply is available and bulk packaging is acceptable.

UWR1C220MCL1GB (Nichicon - Obsolete Status): This part provides full electrical and mechanical compatibility but carries an obsolete product status designation. It is available in Cut Tape and Digi-Reel packaging formats with 4324 units currently in stock. Use only when the primary part is unavailable and the design timeline permits extended lead times. ROHS3 compliance is maintained.

VE-220M1CTR-0405S (SURGE - Active Status): This part maintains active product status with identical electrical and mechanical specifications. It is supplied in Cut Tape packaging with 4630 units currently in stock. This part is suitable as a primary alternative when bulk packaging is not required, and it offers the advantage of active manufacturer support.

All three parts meet the electrical performance requirements for general purpose aluminum electrolytic capacitor applications at 22 µF, 16 V with ±20% tolerance and 2000-hour lifetime ratings at 85°C.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for successful substitution? A: Capacitance (22 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C) must match exactly. All listed substitute parts meet these specifications.

Q: Are the physical dimensions identical across all three parts? A: Yes. All parts share the same diameter (0.157" / 4.00mm), height (0.217" / 5.50mm), and surface mount land size (0.169" x 0.169" / 4.30mm x 4.30mm). They are footprint-compatible for SMD assembly.

Q: What is the difference in packaging between these parts? A: The primary part (226SML016MD4) comes in bulk packaging. The Nichicon substitute (UWR1C220MCL1GB) offers Cut Tape and Digi-Reel options. The SURGE substitute (VE-220M1CTR-0405S) is supplied in Cut Tape format. Select based on your procurement and assembly workflow requirements.

Q: Why is one part marked as obsolete? A: The Nichicon UWR1C220MCL1GB carries an obsolete product status, indicating it is no longer in active production. However, it remains electrically and mechanically equivalent and is currently available in inventory (4324 units). Use this part only when newer alternatives are unavailable.

Q: Do all parts have the same compliance certifications? A: All three parts meet ROHS3 compliance. The primary and Nichicon parts are rated MSL 1 (unlimited moisture sensitivity). The SURGE part is rated as Not Applicable for MSL. All parts are REACH Unaffected with identical HTSUS classification (8532.22.0020).

Q: How do ripple current and ESR ratings affect substitution? A: The main part specifies 12.057 Ohm ESR @ 120Hz with 30 mA and 45 mA ripple current ratings. Substitute parts show variations in these parameters (ESR not specified for UWR part, different ripple current ratings). These variations are acceptable for general purpose applications as they remain within the acceptable operating envelope for the capacitance and voltage class.
