2SXB100M Equivalent & Substitute Parts

Part Overview

The 2SXB100M is a 100 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C, making it suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SXB100M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Aluminum Polymer (exact match required)

Allowable Parameter Variations:

• Voltage Rating: May be equal to or greater than 2 V (higher voltage ratings provide backward compatibility)
• ESR: May be equal to or lower than 13 mOhm (lower ESR is acceptable and often beneficial)
• Lifetime @ Temperature: May be equal to or greater than 2000 Hrs @ 105°C
• Operating Temperature Range: Must encompass or match -55°C ~ 105°C

The substitute part EEF-SX0G101R meets all mandatory matching criteria and provides improved electrical characteristics through reduced ESR (9 mOhm versus 13 mOhm) and higher voltage rating (4 V versus 2 V).

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0G101R (Panasonic Electronic Components) is a direct functional substitute for the obsolete 2SXB100M. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The substitute part provides improved electrical performance through lower ESR (9 mOhm versus 13 mOhm) and higher voltage rating (4 V versus 2 V), making it suitable for direct replacement in applications originally designed for the 2SXB100M. The higher voltage rating ensures compatibility with circuits operating at or below 2 V.

The EEF-SX0G101R carries a product status of "Not For New Designs," indicating it is suitable for replacement and maintenance applications but may not be recommended for new product development. For new designs, consultation with component suppliers for current-generation alternatives is advised.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0G101R replace the 2SXB100M in existing designs?

A: Yes. The EEF-SX0G101R is electrically and mechanically compatible. It matches the 100 µF capacitance, ±20% tolerance, 2917 package, and surface mount configuration. The higher 4 V rating and lower 9 mOhm ESR provide improved performance margins.

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

A: The substitute part's 4 V rating is higher than the original 2 V specification. In capacitor applications, a higher voltage rating does not affect operation at lower voltages and provides additional safety margin. The component will function correctly in circuits designed for 2 V operation.

Q: Are there physical dimension differences between these parts?

A: Both components use the 2917 (7343 Metric) package with identical land sizes (0.287" L x 0.169" W / 7.30mm x 4.30mm). The seated height of the substitute is 0.079" (2.00mm) versus 0.075" (1.90mm) for the original, a negligible difference that does not affect PCB layout or assembly.

Q: What does "Not For New Designs" mean for the substitute part?

A: This status indicates the EEF-SX0G101R is available for replacement and maintenance of existing products but may have limited long-term availability. For new product development, current-generation alternatives should be evaluated.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2SXB100M and EEF-SX0G101R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
