Substitute Part Grouping Explanation

Substitution of the 2SW270M is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 270 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• ESR: 9 mOhm (exact match required for electrical performance)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required for reliability)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory compliance)

The EEF-SX0D271ER from Panasonic Electronic Components meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D271ER be used as a direct replacement for the 2SW270M?

A: Yes. Both components have identical capacitance (270 µF), voltage rating (2 V), tolerance (±20%), ESR (9 mOhm), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and package dimensions (2917 / 7343 Metric). Direct PCB substitution is supported without design modification.

Q: Are there physical dimension differences between these parts?

A: The surface mount land size and length/width dimensions are identical (0.287" L x 0.169" W / 7.30mm x 4.30mm). The seated height differs: 2SW270M is 0.114" (2.90mm) maximum, while EEF-SX0D271ER is 0.079" (2.00mm) maximum. This difference does not affect PCB compatibility or electrical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 2SW270M and EEF-SX0D271ER are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in ripple current capability?

A: The 2SW270M supports 4.6 A @ 100 kHz, while the EEF-SX0D271ER supports 6.3 A @ 100 kHz. The substitute part provides higher ripple current capacity, making it suitable for applications with equal or lower ripple current demands.

Q: Why is the 2SW270M listed as obsolete?

A: The 2SW270M is no longer in active production. The EEF-SX0D271ER from Panasonic maintains active status and is the recommended equivalent for new designs and ongoing production requirements.
