Engineering Selection Recommendations

Primary Substitute: 16YXF330MEFC8X11.5 (Rubycon)

The Rubycon 16YXF330MEFC8X11.5 is a direct electrical equivalent to the SURGE RZW331M1CBK-0811S. Both components meet ROHS3 compliance requirements and operate within the identical temperature range of -40°C to 105°C. The substitute part maintains all critical electrical specifications: 330 µF capacitance, ±20% tolerance, and 16 V rated voltage.

The Rubycon component is classified as "Not For New Designs," indicating it remains available for existing applications and legacy system support but is not recommended for new product development initiatives. The SURGE RZW331M1CBK-0811S, with active product status, is the preferred choice for new designs requiring this capacitance and voltage rating.

Both components are packaged as radial through-hole aluminum electrolytic capacitors with identical mechanical form factors, enabling direct board-level substitution without circuit redesign or PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 16YXF330MEFC8X11.5 be used as a direct replacement for the SURGE RZW331M1CBK-0811S?

A: Yes. Both components share identical electrical specifications: 330 µF capacitance, ±20% tolerance, 16 V rated voltage, and polar radial through-hole packaging. The mechanical dimensions are compatible for direct board-level substitution.

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

A: This designation indicates the Rubycon 16YXF330MEFC8X11.5 is available for replacement and repair applications but should not be selected for new product development. The SURGE RZW331M1CBK-0811S, with active status, is the appropriate choice for new designs.

Q: Are both parts RoHS compliant?

A: Yes. Both the SURGE RZW331M1CBK-0811S and Rubycon 16YXF330MEFC8X11.5 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching capacitance (330 µF), voltage rating (16 V), tolerance (±20%), polarization (polar), mounting type (through hole), package type (radial can), operating temperature range (-40°C to 105°C), and RoHS compliance status.

Q: Do the physical dimensions differ between these components?

A: The Rubycon part specifies dimensions of 0.315" diameter (8.00 mm) with 0.512" maximum seated height (13.00 mm) and 0.138" lead spacing (3.50 mm). The SURGE part does not provide dimensional specifications in the available data. Verify physical dimensions against your PCB layout requirements before final component selection.

Q: What is the ripple current rating for the substitute part?

A: The Rubycon 16YXF330MEFC8X11.5 is rated for 280 mA ripple current at 120 Hz (low frequency) and 400 mA ripple current at 100 kHz (high frequency). Confirm these ratings meet your circuit's ripple current requirements.
