Equivalent & Substitute Parts for 2SWZ330M1.9X7.3

Part Overview

The 2SWZ330M1.9X7.3 is a 330 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the PC-CON and SWZ series. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product roadmap. The part is housed in a 2917 (7343 Metric) surface mount package with a maximum seated height of 1.90mm and operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Due to its obsolescence status, identifying parametrically equivalent alternatives is essential for design continuity and supply chain management. Substitute parts must maintain identical electrical characteristics and physical dimensions to ensure direct replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MPL337M0DG19TRX0 be used as a direct replacement for 2SWZ330M1.9X7.3 without circuit modification?

A: Yes. Both parts are parametrically identical across all specified electrical and mechanical parameters, including capacitance, voltage rating, ESR, operating temperature range, and physical dimensions. No circuit redesign is required.

Q: What is the significance of the "Not For New Designs" status on the Rubycon part?

A: This designation indicates the manufacturer has discontinued active development and support for this product line. The Manyue equivalent, with Active status, provides assured long-term availability and supply continuity.

Q: Are the physical dimensions and package footprints identical?

A: Yes. Both parts use the 2917 (7343 Metric) package with identical dimensions of 7.30mm length, 4.30mm width, and 1.90mm maximum seated height. PCB land patterns and assembly processes remain unchanged.

Q: Do both parts meet the same compliance and moisture sensitivity requirements?

A: Yes. Both components are ROHS3 compliant and rated at MSL 3 (168 Hours), ensuring compatibility with standard surface mount assembly and storage protocols.

Q: Is there any difference in ESR or thermal performance between these parts?

A: No. Both parts specify 9 mOhm ESR and 2000 hours lifetime at 105°C, ensuring identical thermal and electrical performance characteristics.
