Equivalent & Substitute Parts for 6SXB22M

Part Overview

The 6SXB22M is a 22 µF, 6.3 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 production and maintenance applications. The part delivers 13 mOhm equivalent series resistance with a 2000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring low ESR performance in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SXB22M is determined by the following critical parameters:

• Capacitance Value: Must be 22 µF (exact match required)
• Package Footprint: Must be 2917 (7343 Metric) for mechanical compatibility
• Voltage Rating: Must be equal to or greater than 6.3 V
• Type: Aluminum polymer construction required
• Mounting: Surface mount configuration required
• Compliance: RoHS3 compliance maintained

The substitute part EEF-CX1C220R meets these criteria with identical capacitance, package, and mounting specifications. The higher voltage rating (16 V) provides design margin while maintaining the same physical footprint and electrical category.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX1C220R from Panasonic Electronic Components serves as a direct substitute for the obsolete 6SXB22M. Both components maintain ROHS3 compliance and identical mechanical compatibility through the 2917 (7343 Metric) package specification. The substitute part carries a higher voltage rating (16 V versus 6.3 V), which provides additional design margin in applications operating at or below the original 6.3 V specification. The ESR differential (40 mOhm versus 13 mOhm) should be evaluated in ripple-current-sensitive applications; however, the substitute's ripple current rating (3.2 A @ 100 kHz) exceeds the original specification (3 A @ 100 kHz), offsetting the higher ESR in most general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX1C220R replace the 6SXB22M in existing designs?

A: Yes. Both parts share identical capacitance (22 µF), package footprint (2917 / 7343 Metric), mounting type (surface mount), and operating temperature range (-55°C ~ 105°C). The substitute's higher voltage rating (16 V) is compatible with circuits designed for 6.3 V operation.

Q: What is the difference in ESR between these parts?

A: The 6SXB22M has 13 mOhm ESR, while the EEF-CX1C220R has 40 mOhm ESR. In applications where low ESR is critical for ripple current handling or thermal performance, this difference should be evaluated against the substitute's ripple current capability (3.2 A @ 100 kHz versus 3 A @ 100 kHz).

Q: Are both parts RoHS compliant?

A: Yes. Both the 6SXB22M and EEF-CX1C220R are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Will the substitute fit the same PCB footprint?

A: Yes. Both parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) and 0.075" maximum seated height (1.90 mm). No PCB layout modifications are required.

Q: What is the product status of the substitute part?

A: The EEF-CX1C220R is classified as "Not For New Designs." While suitable for replacement in existing applications, new designs should consider current-generation alternatives from the manufacturer's active product portfolio.
