Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select SEK220M160ST (CDE) as the primary direct replacement. This part maintains the 160 V rating, 22 µF capacitance, and ±20% tolerance of the original SH220M160ST while offering active product status. The SEK series provides an extended operating temperature range (-40°C to 105°C) compared to the original (-25°C to 105°C), with reduced height (16.00 mm vs. 20.00 mm), improving PCB space efficiency. Both parts are ROHS3 compliant.

For High-Availability Replacement (160 V Rating):

Select 226CKE160MLN (CDE/Illinois Capacitor) when maximum inventory availability is required. This part offers the highest stock level (19,941 pieces) with identical electrical specifications to the original. The reduced height (14.00 mm) provides additional PCB clearance. Applications requiring bypass and decoupling functions benefit from the higher ripple current ratings (150 mA @ 120 Hz, 270 mA @ 100 kHz).

For Extended Lifetime Applications (160 V Rating):

Select EEU-ED2C220 (Panasonic) for applications requiring enhanced reliability. This part extends the lifetime to 8000 hours @ 105°C (compared to 2000 hours in the original), with significantly higher ripple current capacity (200 mA @ 120 Hz, 500 mA @ 100 kHz). The part maintains the 160 V rating and 22 µF capacitance with ROHS3 compliance and unlimited moisture sensitivity level.

For Voltage-Upgraded Applications (200 V or 250 V Rating):

Select EEU-EB2D220 (Panasonic, 200 V) or EEU-ED2E220 (Panasonic, 250 V) when circuit design permits higher voltage ratings. These upgrades provide extended lifetime (5000 or 8000 hours @ 105°C) and improved ripple current handling while maintaining the same 22 µF capacitance and ±20% tolerance. The 200 V and 250 V ratings offer additional safety margin in applications with voltage transients or design headroom requirements.

For Extended Temperature Range:

Select EKXG251ELL220MJ20S (Chemi-Con, 250 V) when operating temperature range must extend to -40°C. This part combines the widest temperature specification (-40°C to 105°C) with 250 V rating, 8000-hour lifetime, and active product status. The KXG series is ROHS3 compliant and REACH unaffected.

All recommended substitutes maintain through-hole mounting, 5.00 mm lead spacing, 10.00 mm diameter, radial can package, and ROHS3 compliance required for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q1: Can I use a 200 V or 250 V rated capacitor in place of the 160 V SH220M160ST?

A: Yes. Higher voltage-rated capacitors are electrically compatible with circuits designed for lower voltage ratings. The 200 V and 250 V variants (EEU-EB2D220, EEU-ED2D220, EEU-ED2E220, EKXG251ELL220MJ20S) provide additional voltage margin and are suitable direct substitutes. Physical dimensions remain identical (10.00 mm diameter, 5.00 mm lead spacing), ensuring PCB compatibility.

Q2: What is the difference between the SEK220M160ST and the original SH220M160ST?

A: Both parts share identical electrical specifications (22 µF, 160 V, ±20% tolerance, 2000 Hrs @ 105°C). The SEK220M160ST offers active product status (vs. obsolete), extended operating temperature range (-40°C to 105°C vs. -25°C to 105°C), and reduced height (16.00 mm vs. 20.00 mm). The SEK series is the recommended direct replacement from CDE.

Q3: Why do some substitute parts have different heights?

A: Height variation (14.00 mm to 22.00 mm) reflects different internal construction and lifetime ratings. Parts with extended lifetime (5000 or 8000 hours @ 105°C) typically require larger form factors. Height differences are acceptable provided PCB clearance permits. The 226CKE160MLN offers the most compact height (14.00 mm) while maintaining 2000-hour lifetime.

Q4: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions. The original SH220M160ST is also ROHS3 compliant.

Q5: Which substitute offers the best ripple current performance?

A: The EEU-ED2C220 (Panasonic) provides the highest ripple current capacity at 200 mA @ 120 Hz and 500 mA @ 100 kHz, combined with 8000-hour lifetime at 160 V rating. For 250 V applications, the EEU-ED2E220 delivers 224 mA @ 120 Hz and 560 mA @ 100 kHz.

Q6: Can I substitute the UPW2C220MPD for the SH220M160ST?

A: The UPW2C220MPD is electrically compatible (22 µF, 160 V, ±20% tolerance) with identical ripple current specifications. However, this part is also obsolete. While 912 pieces are in stock, active-status alternatives (SEK220M160ST, 226CKE160MLN, EEU-ED2C220) are preferred for long-term supply chain reliability.

Q7: What is the ESR (Equivalent Series Resistance) of the substitute parts?

A: The original SH220M160ST specifies 9.04 Ohm @ 120 Hz. The SEK220M160ST provides 9.05 Ohm @ 120 Hz (nearly identical). The 226CKE160MLN specifies 11.304 Ohm @ 120 Hz. Panasonic parts (EEU series) do not publish ESR values in the provided specifications. ESR variations are acceptable provided ripple current and thermal performance meet application requirements.

Q8: Which substitute has the highest inventory availability?

A: The 226CKE160MLN (CDE/Illinois Capacitor) offers the highest inventory with 19,941 pieces in stock, compared to 951 pieces of the original SH220M160ST. This part is recommended for applications requiring immediate availability and long-term supply security.

Q9: Do all substitutes maintain the same lead spacing and diameter?

A: Yes. All substitute parts maintain 5.00 mm lead spacing and 10.00 mm diameter, ensuring direct PCB footprint compatibility. Height variations do not affect lead spacing or diameter.

Q10: What is the difference between EEU-EB2C220 and EEU-ED2C220?

A: Both are Panasonic 22 µF, 160 V, ±20% tolerance parts. The EEU-EB2C220 (EB-A series) provides 5000-hour lifetime with 258.5 mA @ 120 Hz ripple current. The EEU-ED2C220 (ED-A series) provides 8000-hour lifetime with 200 mA @ 120 Hz ripple current. Selection depends on whether extended lifetime or higher ripple current capacity is prioritized.
