Substitute Part Grouping Explanation

Substitution of the 6SW180M is based on strict equivalence across the following critical parameters:

• Capacitance Value: 180 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The Panasonic EEF-CX0J181R meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CX0J181R is the qualified substitute for the obsolete Rubycon 6SW180M. Both components meet identical electrical and mechanical specifications for the core substitution parameters: capacitance, voltage rating, tolerance, package type, operating temperature range, and lifetime rating. Both components carry ROHS3 compliance and REACH unaffected status.

The EEF-CX0J181R offers the additional advantage of active product status, ensuring continued availability and supply chain support. The substitute part exhibits higher ripple current capability (5.1 A versus 4.6 A at 100 kHz) and a lower seated height (1.90 mm versus 2.90 mm), which may provide benefits in space-constrained applications. The ESR specification of the substitute (15 mOhm) is higher than the original part (9 mOhm), but both values remain within acceptable ranges for general-purpose applications at the specified voltage and capacitance ratings.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J181R be used as a direct replacement for the 6SW180M on existing PCBs?

A: Yes. Both components share identical package dimensions (2917/7343 Metric) and surface mount land patterns (0.287" L x 0.169" W / 7.30 mm x 4.30 mm). The substitute part has a lower seated height (1.90 mm versus 2.90 mm), which presents no compatibility issues for standard PCB assembly.

Q: Are there any electrical performance differences between these parts?

A: The core electrical specifications—capacitance, voltage rating, tolerance, and operating temperature range—are identical. The substitute part has higher ESR (15 mOhm versus 9 mOhm) and higher ripple current capability (5.1 A versus 4.6 A at 100 kHz). These differences do not affect substitution validity for general-purpose applications.

Q: Why is the original part listed as obsolete?

A: The Rubycon 6SW180M is classified as obsolete by the manufacturer. The Panasonic EEF-CX0J181R is an active product with confirmed ongoing availability, making it the appropriate choice for new designs and ongoing production support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 6SW180M and EEF-CX0J181R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the difference in packaging between these parts?

A: The 6SW180M is supplied in standard packaging, while the EEF-CX0J181R is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility.
