Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SWZ330MR09 are identified based on the following critical parameters that determine functional equivalence:

• Capacitance Value: 330 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• ESR: 9 mOhm (exact match required for electrical performance)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required for reliability)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Type: Aluminum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Voltage rating tolerance is permitted within the following constraint: substitute parts must have a rated voltage equal to or greater than the original 2 V specification to maintain or exceed electrical safety margins.

Parameter Comparison

Engineering Selection Recommendations

EEF-SX0E331ER (Panasonic Electronic Components) qualifies as a direct manufacturer substitute. This part maintains all critical electrical parameters identical to the 2SWZ330MR09 while offering a higher voltage rating of 2.5 V, which provides additional electrical safety margin. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification. Higher ripple current capability (6.3 A @ 100 kHz versus 3 A @ 100 kHz) represents an enhanced performance characteristic.

MPL337M0DG19TRX0 (Manyue) qualifies as a parametric equivalent substitute. This part matches all critical electrical and mechanical parameters of the original 2SWZ330MR09, including identical voltage rating of 2 V, ESR, lifetime rating, and package dimensions. The part is in active production status with ROHS3 compliance and REACH unaffected certification. Physical height dimension is identical at 0.075" (1.90mm).

Both substitute parts are suitable for direct replacement in applications where the 2SWZ330MR09 is specified, provided that component procurement and supply chain requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0E331ER be used as a direct replacement for 2SWZ330MR09?

A: Yes. The EEF-SX0E331ER maintains identical capacitance, ESR, lifetime rating, operating temperature range, and package dimensions. The higher voltage rating (2.5 V versus 2 V) is compatible with applications designed for 2 V operation and provides additional electrical margin.

Q: Can MPL337M0DG19TRX0 be used as a direct replacement for 2SWZ330MR09?

A: Yes. The MPL337M0DG19TRX0 matches all critical parameters including capacitance, voltage rating, ESR, lifetime rating, operating temperature range, and package dimensions. Physical dimensions are identical.

Q: Are there physical dimension differences between the substitute parts?

A: The EEF-SX0E331ER has a maximum seated height of 0.079" (2.00mm) compared to 0.075" (1.90mm) for both the 2SWZ330MR09 and MPL337M0DG19TRX0. This 0.004" (0.10mm) difference must be evaluated against PCB assembly clearance requirements.

Q: What is the difference in ripple current capability?

A: The 2SWZ330MR09 and MPL337M0DG19TRX0 are rated for 3 A @ 100 kHz ripple current. The EEF-SX0E331ER is rated for 6.3 A @ 100 kHz, representing enhanced ripple current handling capability suitable for higher frequency switching applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
