Equivalent & Substitute Parts for SH222M035ST

Part Overview

The SH222M035ST is a 2200 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 903 pieces currently in stock. The part is designed for general-purpose applications requiring through-hole mounting with a 0.295" (7.50 mm) lead spacing and 0.630" (16.00 mm) diameter can.

Due to the obsolete status of the SH222M035ST, identification of equivalent and substitute parts is necessary to ensure design continuity and procurement availability. Substitute parts maintain the same electrical specifications (2200 µF capacitance, 35 V rated voltage, ±20% tolerance) and mechanical form factor while offering active product status and improved availability.

Engineering Selection Recommendations

Upgrade Path (Recommended for New Designs):

The SEK222M035ST represents the direct upgrade from the obsolete SH222M035ST. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications (2200 µF, 35 V, ±20%, 100 mOhm ESR, 2000 Hrs @ 105°C). The SEK222M035ST is Active status with extended operating temperature range (-55°C to 105°C versus -40°C to 105°C). This part provides the highest compatibility with existing designs.

Extended Lifetime Options:

For applications requiring enhanced reliability, the 228KBM035M, 35YXJ2200M16X25, 35ZLH2200MEFC16X25, EEU-FR1V222, and EKYA350ELL222ML25S all offer 10000 Hrs lifetime @ 105°C compared to the original 2000 Hrs specification. These parts maintain identical capacitance, voltage, and tolerance ratings while providing extended operational life.

High-Availability Alternatives:

The 35ZLH2200MEFC16X25 (Rubycon) offers the highest inventory availability (167,914 pieces) among all substitutes. The 228CKE035M (Cornell Dubilier / Illinois Capacitor) provides 24,597 pieces in stock with Active status and identical electrical performance to the original part.

Compliance Verification:

All listed substitute parts are ROHS3 Compliant and carry Active or Upgrade product status. All parts maintain the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications as the original SH222M035ST.

Height Considerations:

The original SH222M035ST has a maximum seated height of 1.260" (32.00 mm). Substitute parts vary in height from 1.043" to 1.260". For PCB designs with height constraints, verify that the selected substitute part height does not exceed available clearance. The SEK222M035ST and 228KBM035M maintain the original 1.260" height specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different ESR (Equivalent Series Resistance)?

A: Yes. The original SH222M035ST specifies 100 mOhm ESR @ 120 Hz. Substitute parts from Cornell Dubilier / Illinois Capacitor series (228CKE035M, 228CKH035M, 228KBM035M) have ESR values of 120.6 mOhm to 121 mOhm @ 120 Hz. This variation is within acceptable electrical performance parameters for general-purpose and bypass/decoupling applications. Verify ESR compatibility with your specific circuit requirements before selection.

Q: What is the difference between 2000 Hrs and 10000 Hrs lifetime ratings?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches 20% of initial value. The original SH222M035ST specifies 2000 Hrs @ 105°C. Substitute parts offering 10000 Hrs @ 105°C provide extended reliability for long-term applications. Selection depends on application duty cycle and expected service life requirements.

Q: Are all substitute parts mechanically compatible with the original SH222M035ST?

A: All substitute parts maintain identical lead spacing (0.295" / 7.50 mm) and can diameter (0.630" / 16.00 mm), ensuring PCB footprint compatibility. However, seated height varies from 1.043" to 1.260". Verify that your PCB design accommodates the selected substitute part height to avoid mechanical interference with adjacent components or enclosure constraints.

Q: Which substitute part offers the best availability?

A: The 35ZLH2200MEFC16X25 (Rubycon) offers the highest inventory availability with 167,914 pieces in stock. The 228CKE035M (Cornell Dubilier / Illinois Capacitor) provides 24,597 pieces. Both parts are Active status with ROHS3 compliance and identical electrical specifications to the original part.

Q: Can I substitute the SH222M035ST with a part from a different manufacturer?

A: Yes. All listed substitute parts maintain identical capacitance (2200 µF), voltage rating (35 V), tolerance (±20%), lead spacing (0.295"), can diameter (0.630"), and mounting type (through-hole radial). Substitute parts from Rubycon, Panasonic Electronic Components, and Chemi-Con are electrically and mechanically compatible. Verify compliance requirements and performance specifications for your specific application before selection.

Q: What does "Active" product status mean compared to "Obsolete"?

A: Active status indicates the part is currently manufactured and available for procurement. Obsolete status indicates the part is no longer manufactured and available only from existing inventory. The SH222M035ST is Obsolete with 903 pieces remaining in stock. All listed substitute parts are Active status, ensuring long-term procurement availability and design continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant, matching the compliance status of the original SH222M035ST. All parts carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.
