SPA101M0EB Equivalent & Substitute Parts Reference

Part Overview

The SPA101M0EB is a 100 µF, 2.5 V aluminum polymer surface mount capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 2917 (7343 Metric) package. This component is classified as obsolete, indicating discontinued production and limited availability for new procurement. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 1000 hours at 105°C and an equivalent series resistance (ESR) of 9 mOhm.

Due to its obsolete status, identification of equivalent substitute parts is necessary for ongoing design support, maintenance, and production continuity. Substitute components must maintain electrical compatibility across capacitance, voltage rating, ESR, and physical package dimensions while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPA101M0EB is based on the following electrical and mechanical compatibility criteria:

Primary Matching Criteria:

• Capacitance value of 100 µF (exact match required)
• Polymer dielectric type (material consistency)
• Package / Case designation 2917 (7343 Metric) (physical footprint compatibility)
• Surface mount mounting type (assembly process compatibility)
• ESR of 9 mOhm (electrical performance equivalence)

Allowable Parameter Variations:

• Voltage rating may be equal to or greater than 2.5 V (higher voltage rating provides design margin)
• Tolerance of ±20% or tighter (equal tolerance acceptable)
• Operating temperature range may be equal to or wider than -40°C ~ 105°C
• Lifetime at 105°C may be equal to or greater than 1000 hours (improved reliability acceptable)
• Ripple current capability may be equal to or greater than 3 A @ 100 kHz

Compliance Requirements:

• RoHS3 compliance maintained
• ECCN and HTSUS classifications consistent with original part

The substitute parts identified (EEF-SX0G101ER and EEF-SX0G101R) are manufactured by Panasonic Electronic Components and satisfy all primary matching criteria while offering enhanced electrical performance characteristics.

Engineering Selection Recommendations

For Active Production and New Designs:

The EEF-SX0G101ER is the recommended substitute for the obsolete SPA101M0EB. This part is classified as Active product status, ensuring ongoing availability and manufacturing support. It meets all primary electrical and mechanical compatibility requirements while providing enhanced performance characteristics: higher voltage rating (4 V vs. 2.5 V), extended lifetime (2000 hours vs. 1000 hours at 105°C), and increased ripple current capability (6.3 A vs. 3 A @ 100 kHz). The part maintains ROHS3 compliance and is supplied in standard Tape & Reel packaging suitable for automated assembly processes.

For Legacy System Support and Maintenance:

The EEF-SX0G101R provides an alternative substitute option with identical electrical specifications to the EEF-SX0G101ER. However, this part carries a "Not For New Designs" product status designation, indicating that while currently available, it is not recommended for incorporation into new product designs. This part is suitable for field replacement and maintenance applications where existing inventory or design compatibility requires its use. Tape & Reel packaging is available.

Compliance and Regulatory Considerations:

Both substitute parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications as the original SPA101M0EB, ensuring regulatory equivalence for procurement and export documentation purposes.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0G101ER be used as a direct replacement for the SPA101M0EB in existing circuit designs?

A: Yes. The EEF-SX0G101ER is electrically and mechanically compatible with the SPA101M0EB. Both components share identical capacitance (100 µF), tolerance (±20%), ESR (9 mOhm), and package dimensions (2917 / 7343 Metric). The higher voltage rating (4 V vs. 2.5 V) and extended lifetime (2000 hours vs. 1000 hours at 105°C) of the substitute part provide additional design margin and reliability without affecting circuit functionality.

Q: What is the difference between the EEF-SX0G101ER and EEF-SX0G101R?

A: Both parts are manufactured by Panasonic and share identical electrical specifications: 100 µF capacitance, 4 V voltage rating, 9 mOhm ESR, 2000-hour lifetime at 105°C, and 2917 (7343 Metric) package. The primary distinction is product status: EEF-SX0G101ER is classified as Active, while EEF-SX0G101R is classified as Not For New Designs. For new product development, the EEF-SX0G101ER is the preferred choice due to its active status and assured long-term availability.

Q: Are there any physical dimension differences between the main part and substitute parts?

A: The length and width dimensions are identical across all three parts: 0.287" L x 0.169" W (7.30 mm x 4.30 mm). The seated height of the substitute parts is slightly greater: 0.079" (2.00 mm) for both Panasonic parts compared to 0.071" (1.80 mm) for the CDE original. This 0.008" (0.20 mm) difference is within typical PCB assembly tolerances and does not affect mounting compatibility or circuit board layout.

Q: Does the higher voltage rating of the substitute parts affect circuit performance?

A: No. A capacitor with a higher voltage rating than required by the circuit operates identically to one with the exact rated voltage. The 4 V rating of the substitute parts (versus 2.5 V for the original) provides additional design margin and does not alter capacitance, ESR, or ripple current handling characteristics. The capacitor will function correctly in any circuit designed for 2.5 V operation.

Q: What is the significance of the increased ripple current rating in the EEF-SX0G101ER?

A: The EEF-SX0G101ER supports 6.3 A ripple current at 100 kHz, compared to 3 A for the original SPA101M0EB. This enhanced capability indicates improved thermal performance and lower internal heating under AC current stress. In applications where the original part operates near its ripple current limit, the substitute part provides additional operational margin and extended service life.

Q: Are both substitute parts available in the same packaging format as the original?

A: The original SPA101M0EB packaging format is not specified in the available data. Both substitute parts (EEF-SX0G101ER and EEF-SX0G101R) are supplied in Tape & Reel (TR) format, which is the standard packaging for surface mount components in automated assembly environments. This packaging is compatible with standard pick-and-place equipment and reflow soldering processes.

Q: What is the operating temperature range difference, and does it matter?

A: The substitute parts operate across -55°C to 105°C, compared to -40°C to 105°C for the original part. The extended lower temperature limit (-55°C vs. -40°C) provides additional margin for applications exposed to cold environments. The upper temperature limit (105°C) remains identical. This expanded range does not affect performance in applications designed for the original -40°C to 105°C specification.

Q: Are there any compliance or regulatory differences between the parts?

A: No. All three parts carry identical regulatory classifications: ROHS3 Compliant, ECCN EAR99, and HTSUS 8532.22.0020. The substitute parts also carry REACH Unaffected status. These designations ensure equivalent regulatory treatment for procurement, documentation, and export purposes.
