SPSX271M02R-6 Equivalent & Substitute Parts

Part Overview

The SPSX271M02R-6 is a 270 µF, 2 V aluminum-polymer capacitor manufactured by Cornell Dubilier Electronics (CDE) in a 2917 (7343 Metric) surface mount package. This component is classified as obsolete product status. Due to the obsolete status and limited availability of the original part, identifying equivalent and substitute parts is necessary to ensure design continuity and maintain production schedules without requiring complete circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPSX271M02R-6 is determined by the following critical parameters:

• Capacitance Value: Must be 270 µF ±20% tolerance
• Package/Form Factor: Must be 2917 (7343 Metric) surface mount to ensure mechanical compatibility
• Voltage Rating: Substitute must meet or exceed the 2 V rated voltage requirement
• Type: Aluminum-polymer capacitor construction required
• Operating Temperature Range: Must support the -40°C ~ 105°C operational envelope or equivalent

The EEF-SX0E271E7 (Panasonic Electronic Components) meets these substitution criteria while providing enhanced performance characteristics. This part maintains identical capacitance and package specifications while offering higher voltage rating, lower ESR, and extended lifetime rating.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0E271E7 is the designated substitute for the obsolete SPSX271M02R-6. Both parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity. The Panasonic part offers superior thermal stability (2000 Hrs @ 105°C versus 1000 Hrs) and operates across an extended temperature range (-55°C to 105°C). The part is currently in active production status with confirmed inventory availability (1206 pieces in stock), providing supply chain security for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E271E7 be used as a direct replacement for the SPSX271M02R-6? A: Yes. Both parts share identical capacitance (270 µF), tolerance (±20%), and package specification (2917 / 7343 Metric). The Panasonic part operates at a higher voltage rating (2.5 V versus 2 V), which is backward-compatible with the original circuit design.

Q: Are there physical dimension differences between the two parts? A: The parts have identical length and width (0.287" L x 0.169" W / 7.30mm x 4.30mm). The height difference is minimal: SPSX271M02R-6 measures 0.083" (2.10mm) seated height, while EEF-SX0E271E7 measures 0.079" (2.00mm). Both are compatible with the same PCB footprint.

Q: What is the significance of the lower ESR in the substitute part? A: The EEF-SX0E271E7 has a slightly higher ESR (7 mOhm versus 6 mOhm), which represents a negligible 1 mOhm difference. This maintains equivalent performance in most circuit applications.

Q: Why is the ripple current specification higher for the EEF-SX0E271E7? A: The Panasonic part is rated for 7 A ripple current at 100 kHz, compared to 3.5 A for the CDE part. This provides additional design margin and thermal headroom for high-frequency switching applications.

Q: What is the lead time and availability status? A: The EEF-SX0E271E7 is in active production status with 1206 pieces currently available in stock, providing immediate availability for procurement.
