Substitute Part Grouping Explanation

Substitution of the 2SWZ330MR05 is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (minimum requirement)
• Type: Aluminum Polymer (exact match required)

The EEF-SX0D331XE from Panasonic Electronic Components meets all critical substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The EEF-SX0D331XE is the qualified substitute for the 2SWZ330MR05. Selection is based on the following factors:

• Product Status: The EEF-SX0D331XE is classified as active, ensuring continued availability and manufacturing support, whereas the 2SWZ330MR05 is obsolete.
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component procurement.
• Electrical Equivalence: Both parts share identical capacitance, voltage rating, tolerance, and operating temperature specifications, ensuring functional compatibility in circuit applications.
• Physical Compatibility: Both parts use the 2917 (7343 Metric) package with identical land sizes, enabling direct PCB footprint compatibility.

The EEF-SX0D331XE demonstrates superior ripple current handling (7.5 A @ 100 kHz versus 4.6 A @ 100 kHz) and slightly higher ESR (6 mOhm versus 4.5 mOhm), representing acceptable trade-offs for applications requiring the 330 µF, 2 V specification.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D331XE be used as a direct replacement for the 2SWZ330MR05?

A: Yes. Both parts share identical electrical specifications (330 µF, 2 V, ±20% tolerance), identical package dimensions (2917 / 7343 Metric), and identical land sizes. Physical and electrical compatibility is confirmed.

Q: What is the difference in height between these two parts?

A: The 2SWZ330MR05 has a maximum seated height of 0.075" (1.90mm), while the EEF-SX0D331XE has a maximum seated height of 0.079" (2.00mm). This 0.004" (0.10mm) difference is within typical PCB assembly tolerances and does not affect compatibility.

Q: Why does the EEF-SX0D331XE have higher ripple current rating?

A: The ripple current rating reflects the thermal and electrical design characteristics of each manufacturer's polymer capacitor formulation. The EEF-SX0D331XE specification of 7.5 A @ 100 kHz versus 4.6 A @ 100 kHz indicates enhanced performance capability in the Panasonic design.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for electronic component use.

Q: What is the significance of the product status difference?

A: The 2SWZ330MR05 is classified as obsolete, indicating discontinued manufacturing and limited availability. The EEF-SX0D331XE is active, ensuring ongoing production, supply chain stability, and long-term design support.
