2.5SW220M Equivalent & Substitute Parts

Part Overview

The Rubycon 2.5SW220M is a 220 µF, 2.5 V aluminum polymer capacitor in 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The part delivers 9 mOhm ESR with 2000 hours lifetime rating at 105°C, suitable for general-purpose applications requiring compact form factor and low impedance characteristics.

Substitute Part Grouping Explanation

Substitution of the 2.5SW220M is determined by strict equivalence across the following parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Package type: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The Panasonic EEF-SX0E221E7 meets all substitution criteria. Variations in ESR, ripple current capacity, and height do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-SX0E221E7 is a direct substitute for the obsolete Rubycon 2.5SW220M. Both components maintain identical electrical specifications for capacitance, voltage rating, tolerance, and thermal lifetime. Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for current production environments.

The EEF-SX0E221E7 offers improved performance characteristics: lower ESR (7 mOhm versus 9 mOhm) and higher ripple current capacity (7 A versus 4.6 A at 100 kHz). The substitute component features reduced seated height (2.00 mm versus 2.90 mm), which may provide layout advantages in space-constrained applications. Active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E221E7 be used as a direct replacement for the 2.5SW220M?

A: Yes. Both components share identical capacitance (220 µF), voltage rating (2.5 V), package type (2917 Metric), tolerance (±20%), operating temperature range (-55°C to 105°C), and thermal lifetime (2000 Hrs @ 105°C). Footprint compatibility is confirmed through matching surface mount land size (7.30 mm × 4.30 mm).

Q: What are the differences between these two parts?

A: The primary differences are ESR (7 mOhm for Panasonic versus 9 mOhm for Rubycon), ripple current capacity (7 A versus 4.6 A at 100 kHz), and seated height (2.00 mm versus 2.90 mm). The Panasonic part offers superior electrical performance and reduced height. The Rubycon part is obsolete; the Panasonic part is active.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.

Q: Will the reduced height of the EEF-SX0E221E7 affect PCB assembly?

A: No. The reduced seated height (2.00 mm versus 2.90 mm) is a favorable characteristic that may improve clearance in constrained layouts. The footprint and land pattern remain identical.

Q: Is the EEF-SX0E221E7 available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, while the original part number does not specify packaging format in the provided data. Both are surface mount components with identical land patterns suitable for automated assembly.
