2SWZ270MR06 Equivalent & Substitute Parts

Part Overview

The 2SWZ270MR06 is a 270 µF, 2 V aluminum polymer surface mount capacitor manufactured by Rubycon in the PC-CON and SWZ series. This component is designed for general purpose applications requiring low equivalent series resistance and stable performance across extended temperature ranges. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 2SWZ270MR06 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 type: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (exact match or better required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match or better required)
• RoHS compliance: ROHS3 Compliant (required)

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

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0D271ER is a direct functional equivalent to the 2SWZ270MR06 for applications requiring 270 µF, 2 V aluminum polymer capacitors in 2917 package format. Both components meet ROHS3 compliance requirements and share identical electrical specifications for capacitance, voltage rating, tolerance, and lifetime rating.

The EEF-SX0D271ER offers the advantage of active product status with established supply chain availability. The substitute part exhibits higher ripple current capability (6.3 A versus 4.6 A at 100 kHz) and slightly elevated ESR (9 mOhm versus 6 mOhm), which are acceptable variations within the polymer capacitor technology class and do not compromise functional equivalence for general purpose applications.

Physical dimensions are compatible, with maximum seated height differing by 0.004" (0.10 mm), which remains within typical PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D271ER be used as a direct replacement for the 2SWZ270MR06 in existing designs?

A: Yes. Both components share identical capacitance (270 µF), voltage rating (2 V), tolerance (±20%), package type (2917), and operating temperature range (-55°C to 105°C). PCB footprints and land patterns are compatible.

Q: What is the significance of the ESR difference between the two parts?

A: The 2SWZ270MR06 specifies 6 mOhm ESR while the EEF-SX0D271ER specifies 9 mOhm ESR. This 3 mOhm difference is within normal manufacturing variation for aluminum polymer capacitors and does not affect general purpose application performance.

Q: Are there packaging differences between these parts?

A: Both components use the 2917 (7343 Metric) package with surface mount configuration. Maximum seated height differs by 0.004" (0.10 mm), which is negligible for standard PCB assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The EEF-SX0D271ER is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original 2SWZ270MR06.

Q: Why is the 2SWZ270MR06 listed as obsolete?

A: Rubycon has discontinued this part number. The EEF-SX0D271ER from Panasonic remains in active production and provides equivalent functionality for new designs and production support.
