SPA221M0EB Equivalent & Substitute Parts Reference

Part Overview

The SPA221M0EB is a 220 µF, 2.5 V aluminum polymer capacitor manufactured by Cornell Dubilier Electronics in a 2917 (7343 Metric) surface mount package. The product is currently obsolete, requiring identification of functionally equivalent alternatives for ongoing applications. Equivalent substitutes must maintain the same capacitance, voltage rating, and physical footprint while meeting or exceeding performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following criteria:

Mandatory Parameters (Must Match Exactly):

• Capacitance: 220 µF
• Voltage Rating: 2.5 V
• Tolerance: ±20%
• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount

Performance Parameters (Equal or Better):

• ESR (Equivalent Series Resistance): 7 mΩ or lower
• Lifetime @ 105°C: 1000 Hours or greater
• Operating Temperature Range: Must encompass or exceed -40°C to 105°C
• Ripple Current Capability: 3.5 A @ 100 kHz or greater

Compliance Requirements:

• RoHS3 Compliant

All substitute parts listed in this reference maintain the mandatory parameters. Performance variations in ESR, lifetime, and ripple current are documented in the parameter comparison table for engineering selection.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitutes (Actively Manufactured):

EEF-SX0E221E7 is the recommended direct substitute for the obsolete SPA221M0EB. This part provides identical capacitance, voltage, tolerance, and ESR specifications with superior performance characteristics including extended lifetime (2000 hours at 105°C versus 1000 hours) and increased ripple current capability (7 A versus 3.5 A at 100 kHz). The operating temperature range extends to -55°C, providing broader environmental coverage than the original part. Panasonic Electronic Components maintains active production status with ROHS3 compliance and REACH unaffected status.

Alternative Substitutes (Active Production):

EEF-SX0E221ER and EEF-SX0E221R provide functionally equivalent substitution with 9 mΩ ESR (versus 7 mΩ in the primary substitute and original). Both maintain 2000-hour lifetime at 105°C and support extended temperature operation to -55°C. EEF-SX0E221ER specifies 6.3 A ripple current at 100 kHz. These alternatives are suitable where slightly elevated ESR is acceptable within circuit design tolerances.

Secondary Alternative (Limited Performance):

EEF-CX0E221R provides electrical equivalence with higher ESR (15 mΩ) and reduced ripple current capability (5.1 A at 100 kHz). This substitute is appropriate only where circuit design accommodates elevated ESR and lower ripple current characteristics. All active Panasonic substitutes are ROHS3 compliant and in production status.

Frequently Asked Questions (FAQ)

Q: Can EEF-CX0E221R directly replace SPA221M0EB in any circuit?

A: EEF-CX0E221R maintains mandatory electrical parameters (220 µF, 2.5 V, ±20% tolerance) and physical footprint compatibility. However, the 15 mΩ ESR specification is substantially higher than the original 7 mΩ ESR. Circuit application determines acceptable ESR tolerance. High-frequency ripple current applications benefit from lower ESR; the 5.1 A specification at 100 kHz versus the original 3.5 A must be evaluated against circuit ripple current requirements.

Q: What are the physical compatibility considerations?

A: All substitute parts use the identical 2917 (7343 Metric) surface mount package with the same land pattern (0.287" L x 0.169" W). Height varies between 1.90 mm and 2.00 mm among substitutes, compared to 2.80 mm for the original SPA221M0EB. The reduced height offers board layout advantages and is mechanically compatible with standard board clearance specifications for this package class.

Q: How do temperature operating ranges affect substitution?

A: The original SPA221M0EB operates from -40°C to 105°C. All Panasonic substitutes extend the lower temperature limit to -55°C while maintaining the 105°C upper limit. This expanded range provides superior performance in applications subject to lower temperature extremes. For standard -40°C to 105°C operation, all substitutes exceed the original specification.

Q: What is the significance of longer lifetime specifications in substitute parts?

A: The SPA221M0EB specifies 1000 hours lifetime at 105°C. All Panasonic substitutes specify 2000 hours at 105°C, indicating extended functional life under elevated temperature stress. This doubled rating reflects improvements in polymer capacitor technology and provides longer service intervals for reliability-critical applications.

Q: Are there any compliance differences between substitutes?

A: All parts including SPA221M0EB are ROHS3 compliant. Panasonic substitutes additionally specify REACH unaffected status. Compliance positions these parts favorably for regulated manufacturing and export applications. The original part's obsolete status does not affect compliance certification for previously manufactured inventory.

Q: Which substitute offers the best direct performance match?

A: EEF-SX0E221E7 provides the closest technical alignment to SPA221M0EB with identical 7 mΩ ESR and superior performance in lifetime and ripple current specifications. The part is in active production with full Panasonic support and documentation availability.
