SPA101M04R

Part Overview

The SPA101M04R is a 100 µF, 4 V aluminum polymer capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 2917 (7343 Metric) surface mount package. This component is classified as Obsolete, making identification of suitable substitutes necessary for ongoing production and maintenance applications. The part delivers 1000 hours of operating life at 105°C with 9 mOhm equivalent series resistance and is rated for 3 A ripple current at 100 kHz.

Substitute Part Grouping Explanation

Direct substitution of the SPA101M04R is determined by the following critical parameters that must be preserved:

Capacitance: 100 µF (exact match required)
Voltage Rating: 4 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: 2917 (7343 Metric) surface mount (exact match required)
ESR: 9 mOhm (exact match required)
RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

Two substitutes from Panasonic Electronic Components meet all substitution criteria: EEF-SX0G101ER and EEF-SX0G101R. Both are Panasonic SP-Cap SX series polymer capacitors with identical electrical specifications to the main part across all critical parameters.

Engineering Selection Recommendations

Primary Recommendation: EEF-SX0G101ER

The Panasonic EEF-SX0G101ER is the preferred substitute. This component carries Active product status, ensuring continued availability and manufacturer support. It meets all electrical equivalence criteria with identical capacitance, voltage rating, tolerance, and ESR specifications. The part delivers enhanced performance characteristics with 2000 hours lifetime at 105°C and 6.3 A ripple current capacity at 100 kHz, both exceeding the original SPA101M04R specifications. Operating temperature range extends to -55°C, providing broader application flexibility. ROHS3 compliance and Tape & Reel packaging with 7147 pieces in stock support production continuity.

Alternative Substitute: EEF-SX0G101R

The Panasonic EEF-SX0G101R meets all critical electrical specifications and achieves identical package compatibility. However, this part carries Not For New Designs status, limiting its application to legacy or maintenance scenarios. The component maintains ROHS3 compliance and comparable performance enhancements over the original part, with 3679 pieces available in inventory. This option is suitable for direct replacement in existing designs but should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101ER and EEF-SX0G101R be used interchangeably with SPA101M04R?

A: Both Panasonic parts meet identical electrical specifications for capacitance, voltage rating, tolerance, and ESR. Package dimensions are compatible within the 2917 (7343 Metric) footprint, with a maximum seated height difference of 0.004" (0.10 mm) that does not impact board assembly or thermal design. Selection depends on product status requirements: EEF-SX0G101ER for new designs and EEF-SX0G101R for legacy applications only.

Q: What are the key differences between the main part and the substitutes?

A: The Panasonic substitutes provide improved reliability with 2000-hour lifetime versus 1000 hours for the original part. Operating temperature range is extended to -55°C minimum. EEF-SX0G101ER offers enhanced ripple current capacity at 6.3 A compared to 3 A in the SPA101M04R. Electrical parameters—capacitance, voltage, tolerance, and ESR—remain identical across all parts.

Q: Why is the SPA101M04R classified as Obsolete?

A: Obsolete status indicates discontinued production by the manufacturer. Panasonic equivalents with Active status are available to support ongoing production needs and provide superior performance characteristics.

Q: Are there any mounting or assembly considerations when substituting these parts?

A: All parts utilize identical 2917 (7343 Metric) surface mount packaging with compatible land patterns. The 0.004" height difference between SPA101M04R and Panasonic substitutes does not require design changes to printed circuit board layouts or assembly processes.

Q: Which substitute should be selected for new product designs?

A: EEF-SX0G101ER must be selected for new designs due to Active product status. EEF-SX0G101R carries Not For New Designs classification and is reserved for maintenance and repair of existing products.
