SH222M016ST Equivalent & Substitute Parts Reference

Part Overview

The SH222M016ST is a 2200 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 1039 units available in current inventory. The part is designed for general-purpose applications requiring through-hole mounting with a rated lifetime of 2000 hours at 105°C.

Substitute Part Grouping Explanation

Substitution eligibility for the SH222M016ST is determined by strict adherence to the following parameters:

Critical Matching Parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required for PCB footprint compatibility)

Important Compatibility Parameters:

Operating Temperature Range: Must support -40°C to 105°C minimum
RoHS Compliance: ROHS3 Compliant status required
Lifetime @ 105°C: Substitute parts should meet or exceed 2000 hours; extended lifetimes (5000, 6000, or 10000 hours) provide improved reliability margins

Physical Dimensions:

Diameter: 0.492" to 0.512" (12.50mm to 13.00mm) — minor variations acceptable within can package standards
Height: 0.827" to 1.043" (21.00mm to 26.50mm) — variations acceptable provided PCB clearance is verified

All substitute parts listed meet these critical parameters and are sourced from active manufacturers with current production status and full inventory availability.

Engineering Selection Recommendations

Primary Recommendation: SEK222M016ST (Cornell Dubilier Electronics)

The SEK222M016ST is the direct active-production upgrade from the obsolete SH222M016ST. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications (2200 µF, 16 V, ±20%, 2000 Hrs @ 105°C, 120 mOhm ESR). The SEK series extends the operating temperature range to -55°C to 105°C, providing enhanced cold-temperature performance. Physical dimensions differ slightly (21.00 mm height versus 25.00 mm), requiring PCB layout verification. With 8959 units in inventory and active product status, this part ensures design continuity and manufacturer support.

Secondary Recommendations for Extended Reliability:

For applications requiring extended component lifetime, the following active parts provide 10000-hour ratings at 105°C:

16ZLH2200MEFC12.5X20 (Rubycon): 10000-hour lifetime, 17 mOhm impedance, 11537 units in stock. Compact 22.00 mm height.
EEU-FR1C222 (Panasonic Electronic Components): 10000-hour lifetime, 18 mOhm impedance, 1148 units in stock. Compact 22.00 mm height.
EKYB160ELL222MK20S (Chemi-Con): 10000-hour lifetime, 27 mOhm impedance, 2330 units in stock. Compact 21.50 mm height.

Considerations for Height-Constrained Designs:

Parts with reduced height (21.00 mm to 21.50 mm) include SEK222M016ST, EKYA160ELL222MK20S, EKYB160ELL222MK20S, and EKZH160ELL222MK20S. These accommodate space-limited PCB layouts while maintaining full electrical compatibility.

Considerations for Height-Accommodating Designs:

The EKZE160ELL222MK25S (Chemi-Con) matches the original SH222M016ST height of 26.50 mm, minimizing PCB redesign requirements. This part provides 5000-hour lifetime and 18 mOhm impedance with 4600 units in inventory.

Compliance Status:

All substitute parts are ROHS3 compliant and sourced from manufacturers with active production status. All parts support the -40°C to 105°C operating temperature range required by the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the SH222M016ST?

A: All listed substitute parts meet the critical electrical and mechanical parameters: 2200 µF capacitance, 16 V rating, ±20% tolerance, polar configuration, through-hole mounting, radial can package, and 5.00 mm lead spacing. However, physical height variations (21.00 mm to 26.50 mm) require verification of PCB clearance and component placement. The SEK222M016ST is the recommended direct upgrade from the same manufacturer.

Q: What is the difference between ESR and impedance values listed in the comparison table?

A: ESR (Equivalent Series Resistance) and impedance are related but distinct parameters. The SH222M016ST specifies 120 mOhm ESR at 120 Hz. Substitute parts list impedance values measured at different frequencies (typically 100 kHz or higher). These values are not directly comparable; impedance varies with frequency. For applications sensitive to ESR at low frequencies, consult detailed datasheets for frequency-specific measurements.

Q: Why do some substitute parts have longer lifetimes (10000 hours) than the original (2000 hours)?

A: Extended lifetime ratings reflect improved capacitor design and materials in modern production. A 10000-hour rating at 105°C indicates the part will maintain specified performance for a longer operational period under thermal stress. This provides enhanced reliability margins for critical applications. Parts with extended lifetimes are suitable for direct substitution and offer improved long-term performance.

Q: Are there any restrictions on mixing substitute parts from different manufacturers in the same circuit?

A: No electrical restrictions exist for using substitute parts from different manufacturers (Rubycon, Panasonic, Chemi-Con) in the same circuit, provided all parts meet the specified 2200 µF, 16 V, ±20% parameters. However, for production consistency and supply chain management, using parts from a single manufacturer is recommended when possible.

Q: How do I verify PCB compatibility when the substitute part height differs from the original?

A: Measure the available vertical clearance above the component mounting location on your PCB. Compare this clearance to the maximum seated height of the substitute part. The SH222M016ST has a maximum height of 25.00 mm. Substitute parts range from 21.00 mm to 26.50 mm. If the substitute part height exceeds available clearance, select an alternative from the list with reduced height, or verify that adjacent components do not create interference.

Q: What is the significance of the different impedance values among substitute parts?

A: Impedance values (17 mOhm to 41 mOhm) reflect the internal resistance characteristics of each capacitor design. Lower impedance values (17 mOhm) indicate better high-frequency performance and lower voltage ripple. For general-purpose applications, impedance differences within this range are not critical. For high-frequency or high-ripple-current applications, parts with lower impedance (16ZLH2200MEFC12.5X20, EEU-FR1C222, EKZH160ELL222MK20S) are preferred.

Q: Is the SEK222M016ST truly equivalent to the SH222M016ST?

A: The SEK222M016ST is the active-production equivalent from Cornell Dubilier Electronics. Both parts share identical capacitance (2200 µF), voltage (16 V), tolerance (±20%), ESR (120 mOhm), and lifetime (2000 Hrs @ 105°C). The SEK series extends the operating temperature range to -55°C (versus -40°C for SH series), providing enhanced cold-temperature capability. Physical height is reduced from 25.00 mm to 21.00 mm, requiring PCB verification. This is the recommended direct replacement.

Q: Can I use a substitute part with a higher voltage rating (e.g., 25 V instead of 16 V)?

A: No. All substitute parts listed are specified at exactly 16 V. Using a higher-voltage-rated capacitor would alter circuit performance and is not a valid substitution. Voltage rating must match exactly.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets European Union regulations restricting hazardous materials including lead, cadmium, and mercury. All substitute parts listed are ROHS3 compliant, ensuring regulatory compliance for products sold in regulated markets. This is a mandatory requirement for most commercial and industrial applications.
