Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2.5SWZ270MR06 is determined by the following critical parameters:

• Capacitance Value: 270 µF (exact match required)
• Voltage Rating: 2.5 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Type: Aluminum Polymer (exact match required for electrical characteristics)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (minimum requirement)

The Panasonic EEF-SX0E271E7 meets all substitution criteria. While minor variations exist in ESR (7 mOhm vs. 6 mOhm), ripple current rating (7 A vs. 4.6 A @ 100 kHz), and maximum seated height (2.00 mm vs. 1.90 mm), these differences remain within acceptable engineering tolerances for general-purpose applications and do not compromise functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-SX0E271E7 is a direct functional substitute for the obsolete Rubycon 2.5SWZ270MR06. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Panasonic part is currently in active production status with higher inventory availability (1206 pcs vs. 638 pcs), ensuring supply chain continuity. The substitute part offers improved ripple current handling (7 A vs. 4.6 A @ 100 kHz), which provides additional design margin in high-frequency applications. The marginal increase in ESR (1 mOhm) and seated height (0.10 mm) does not impact PCB layout or electrical performance for general-purpose applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E271E7 be used as a direct replacement on existing PCBs designed for the 2.5SWZ270MR06?

A: Yes. Both parts share identical package dimensions (2917 / 7343 Metric), surface mount land size (7.30 mm × 4.30 mm), and electrical specifications (270 µF, 2.5 V, ±20% tolerance). The 0.10 mm difference in maximum seated height (1.90 mm vs. 2.00 mm) does not affect PCB assembly or clearance in standard designs.

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

A: The Panasonic substitute has 7 mOhm ESR compared to 6 mOhm for the Rubycon original. This 1 mOhm increase is negligible for general-purpose applications and does not materially affect voltage ripple, thermal performance, or circuit stability within the specified operating conditions.

Q: Why does the Panasonic part have a higher ripple current rating?

A: The EEF-SX0E271E7 is rated for 7 A ripple current at 100 kHz, compared to 4.6 A for the 2.5SWZ270MR06. This represents improved performance in the substitute part and provides additional design margin for high-frequency switching applications without introducing compatibility issues.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. Regulatory and export compliance requirements are equivalent.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute part?

A: The provided data specifies MSL 3 (168 Hours) for the Rubycon original. Equivalent MSL information for the Panasonic EEF-SX0E271E7 was not included in the substitute part specifications provided.
