2.5SW270M Equivalent & Substitute Parts

Part Overview

The 2.5SW270M is a 270 µF, 2.5 V aluminum polymer capacitor manufactured by Rubycon in the PC-CON and SW series. This surface mount component is designed for general purpose applications requiring compact form factor and low equivalent series resistance. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance requirements. The 2917 (7343 Metric) package provides a standardized footprint for surface mount assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2.5SW270M is determined by strict equivalence across the following parameters: capacitance value (270 µF), voltage rating (2.5 V), tolerance (±20%), package type (2917/7343 Metric), and mounting configuration (surface mount). The substitute part must maintain identical electrical ratings and physical footprint to ensure direct replacement without circuit redesign or PCB modification. Compliance certifications (RoHS3, REACH) and operating temperature range (-55°C to 105°C) are additional qualifying criteria. The identified substitute meets all these requirements while offering improved performance characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0E271E7 (Panasonic) is a direct functional equivalent to the 2.5SW270M. Both components share identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Rubycon part. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The Panasonic substitute offers improved electrical performance with lower ESR (7 mOhm versus 9 mOhm) and higher ripple current capability (7 A versus 4.6 A at 100 kHz). The reduced seated height (2.00 mm versus 2.90 mm) may provide additional design flexibility in space-constrained applications. The identical 2917 (7343 Metric) package ensures PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E271E7 be used as a direct replacement for the 2.5SW270M?

A: Yes. Both components share identical capacitance (270 µF), voltage rating (2.5 V), tolerance (±20%), package type (2917/7343 Metric), and operating temperature range (-55°C to 105°C). The substitute meets all electrical and mechanical requirements for direct substitution without circuit redesign.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Rubycon versus Panasonic), product status (obsolete versus active), and performance characteristics. The Panasonic substitute features lower ESR (7 mOhm versus 9 mOhm), higher ripple current rating (7 A versus 4.6 A at 100 kHz), and reduced seated height (2.00 mm versus 2.90 mm). These represent performance improvements rather than compatibility issues.

Q: Are there any PCB layout considerations when switching to the EEF-SX0E271E7?

A: No layout modifications are required. Both parts use the identical 2917 (7343 Metric) package with matching surface mount land size (0.287" L x 0.169" W / 7.30 mm x 4.30 mm). The reduced height of the substitute part does not affect PCB assembly compatibility.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. The EEF-SX0E271E7 is ROHS3 compliant and REACH unaffected, matching the compliance status of the 2.5SW270M. Both components satisfy equivalent regulatory standards.

Q: Why is the 2.5SW270M listed as obsolete?

A: Rubycon has discontinued this part number. The EEF-SX0E271E7 from Panasonic provides equivalent functionality with active production status, ensuring continued availability for new designs and replacement inventory.
