Equivalent & Substitute Parts for SH221M010ST

Part Overview

The Cornell Dubilier Electronics SH221M010ST is a 220 µF, 10 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing production and maintenance applications. The SH series has been superseded by active product lines offering improved performance characteristics and extended operational lifespans. Equivalent alternatives maintain the core electrical specifications while providing enhanced reliability through extended lifetime ratings and expanded operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SH221M010ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package: Radial, Can (exact match required)
• Mounting: Through Hole (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)

Secondary Compatibility Parameters:

• Operating Temperature Range: Minimum -40°C to maximum 105°C
• RoHS Compliance: ROHS3 Compliant
• Physical Dimensions: Compatible with 0.236" to 0.248" diameter and 0.433" to 0.480" height constraints

All identified substitute parts meet these criteria. Variations in ESR, ripple current ratings, impedance, and lifetime at temperature represent performance enhancements rather than compatibility restrictions.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SEK221M010ST

The Cornell Dubilier Electronics SEK221M010ST represents the direct upgrade path from the obsolete SH221M010ST. Both components share identical manufacturer lineage, ensuring design continuity and supply chain familiarity. The SEK series maintains all electrical specifications while extending the operating temperature range to -55°C ~ 105°C. Product status is active with 1076 units in stock, ensuring availability for immediate deployment.

Secondary Recommendation: EEU-EB1A221S

The Panasonic Electronic Components EEU-EB1A221S offers the highest lifetime rating at 5000 hours @ 105°C, representing a 150% improvement over the original SH221M010ST specification. This component is active in production with 9701 units available. The extended height of 12.20mm requires PCB layout verification but provides superior reliability for long-term applications.

Alternative Recommendation: EKZE100ELL221MF11D

The Chemi-Con EKZE100ELL221MF11D maintains identical physical dimensions to the SH221M010ST (6.30mm diameter, 11.00mm height) and is actively produced with 26003 units in inventory. This option provides the highest ripple current capacity at 405 mA @ 100 kHz and lowest impedance at 130 mOhms.

Obsolete Alternatives (Not Recommended for New Designs):

The Nichicon UHE1A221MED and UPW1A221MED are classified as obsolete and should not be selected for new production applications despite meeting electrical compatibility criteria.

Frequently Asked Questions (FAQ)

Q: Can the SH221M010ST be directly replaced with SEK221M010ST without PCB modification?

A: Yes. Both components share identical lead spacing (2.50mm), mounting type (through hole), and height (11.00mm). The SEK221M010ST diameter increases from 6.00mm to 6.30mm, which does not affect through-hole mounting compatibility. No PCB layout changes are required.

Q: What is the primary advantage of selecting EEU-EB1A221S over SEK221M010ST?

A: The EEU-EB1A221S provides 5000 hours lifetime @ 105°C compared to 2000 hours for SEK221M010ST, representing a 150% improvement in thermal endurance. The trade-off is a height increase from 11.00mm to 12.20mm, requiring verification of available PCB clearance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant certification, maintaining regulatory compliance with the original SH221M010ST.

Q: Why is EKZE100ELL221MF11D preferred over UHE1A221MED despite both being 220 µF 10 V?

A: EKZE100ELL221MF11D is actively produced with 26003 units in inventory, while UHE1A221MED is obsolete. For new designs and ongoing production, active components ensure long-term supply continuity and manufacturer support.

Q: Can operating temperature range differences affect component selection?

A: Operating temperature range differences do not restrict substitution eligibility. The SH221M010ST operates -40°C ~ 105°C. Substitute parts with extended ranges (-55°C ~ 105°C) provide additional capability without reducing compatibility. Selection should be based on actual application temperature requirements.

Q: What is the significance of ESR and impedance variations among substitute parts?

A: ESR and impedance variations affect ripple current handling and high-frequency performance but do not impact basic substitution compatibility. Lower impedance values (EKZE100ELL221MF11D at 130 mOhms) indicate superior high-frequency performance. Selection depends on specific circuit ripple current and frequency requirements.

Q: Are there any moisture sensitivity concerns with these substitute parts?

A: No. All substitute parts list Moisture Sensitivity Level as Not Applicable, indicating no special moisture handling requirements during storage or assembly.
