2SXB220M Equivalent & Substitute Parts

Part Overview

The 2SXB220M is a 220 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part is designed for general-purpose applications requiring low equivalent series resistance and stable performance across extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SXB220M is determined by the following critical parameters:

• Capacitance Value: Must be 220 µF (exact match required)
• Package / Case: Must be 2917 (7343 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount to maintain PCB layout compatibility
• Type: Aluminum Polymer construction ensures equivalent electrical characteristics
• Operating Temperature Range: Must support -55°C ~ 105°C minimum
• Voltage Rating: Must be equal to or greater than 2 V to ensure safe operation
• RoHS Compliance: Must maintain ROHS3 compliance for regulatory alignment

The EEF-CX0G221R from Panasonic Electronic Components meets all substitution criteria. While it features a higher voltage rating (4 V) and slightly elevated ESR (15 mOhm), these parameters remain within acceptable tolerance for general-purpose applications and represent an upgrade in voltage headroom without compromising form factor or thermal performance.

Engineering Selection Recommendations

The EEF-CX0G221R is the qualified substitute for the obsolete 2SXB220M. Selection is supported by the following factors:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain stability.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Mechanical Compatibility: Identical package dimensions and surface mount configuration enable direct PCB layout substitution without redesign.
• Electrical Compatibility: Matching capacitance, operating temperature range, and thermal lifetime ensure functional equivalence in general-purpose applications.
• Performance Enhancement: The higher voltage rating (4 V vs. 2 V) and increased ripple current capability (5.1 A vs. 3 A) provide design margin without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G221R be used as a direct replacement for the 2SXB220M?

A: Yes. Both parts share identical capacitance (220 µF), package (2917 / 7343 Metric), mounting type (Surface Mount), and operating temperature range (-55°C ~ 105°C). The substitute part features a higher voltage rating and improved ripple current handling, making it suitable for direct substitution in general-purpose applications.

Q: What is the significance of the voltage rating difference (2 V vs. 4 V)?

A: The substitute part's higher voltage rating (4 V) provides additional design margin and does not create incompatibility. In applications where the original 2 V rating was sufficient, the 4 V rated component will operate safely with reduced stress on the dielectric material.

Q: Are there any differences in thermal performance between these parts?

A: Both parts specify identical thermal lifetime (2000 Hrs @ 105°C) and operating temperature range (-55°C ~ 105°C). The substitute part's slightly higher ESR (15 mOhm vs. 13 mOhm) represents a minor increase in internal heat generation but remains within acceptable limits for general-purpose applications.

Q: Will the substitute part fit the existing PCB layout?

A: Yes. The EEF-CX0G221R maintains identical physical dimensions (0.287" L x 0.169" W / 7.30mm x 4.30mm) and height (0.075" / 1.90mm), ensuring compatibility with existing surface mount land patterns and assembly processes.

Q: What certifications and compliance standards apply to both parts?

A: Both the 2SXB220M and EEF-CX0G221R are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8532.22.0020, maintaining regulatory alignment for international distribution.
