RZW331M1CBK-0811S Equivalent & Substitute Parts

Part Overview

The RZW331M1CBK-0811S is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by SURGE in radial, can package configuration. This component is rated for 7000 hours at 105°C operating temperature and is designed for general-purpose applications requiring through-hole mounting. The part maintains active product status and is ROHS3 compliant.

Substitute parts become necessary when the primary manufacturer part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternative sources. The RZW331M1CBK-0811S has one identified parametric equivalent that meets the core electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RZW331M1CBK-0811S is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 7000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.138" (3.50mm) (exact match required)
• Size / Dimension: 0.315" Dia (8.00mm) (exact match required)
• Height - Seated (Max): 0.512" (13.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

The identified substitute part 16YXF330MEFC8X11.5 manufactured by Rubycon meets all primary substitution criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

RZW331M1CBK-0811S (Primary Selection)

The RZW331M1CBK-0811S maintains active product status and is the preferred selection for new designs. This part is manufactured by SURGE and carries ROHS3 compliance certification. The component exhibits lower impedance (130 mOhms) and higher ripple current capability at 100 kHz (640 mA), providing superior performance characteristics for high-frequency applications.

16YXF330MEFC8X11.5 (Substitute Selection)

The 16YXF330MEFC8X11.5 manufactured by Rubycon is classified as "Not For New Designs" and functions as a parametric equivalent for existing designs or legacy system support. This part maintains identical electrical and mechanical specifications across all primary substitution criteria and carries ROHS3 compliance. The substitute exhibits higher impedance (250 mOhms) and lower ripple current capability at 100 kHz (400 mA). Selection of this substitute is appropriate only when the primary part is unavailable and the application does not require the enhanced ripple current performance of the primary part.

Frequently Asked Questions (FAQ)

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

A: No. The 16YXF330MEFC8X11.5 carries a "Not For New Designs" product status designation. While it meets all primary electrical and mechanical specifications, new designs should utilize the RZW331M1CBK-0811S, which maintains active product status.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance characteristics. The RZW331M1CBK-0811S has lower impedance (130 mOhms versus 250 mOhms) and higher ripple current capability at 100 kHz (640 mA versus 400 mA). Both parts share identical capacitance, voltage rating, tolerance, lifetime rating, temperature range, and physical dimensions.

Q: Are both parts physically interchangeable on a PCB?

A: Yes. Both parts feature identical lead spacing (0.138" / 3.50mm), can diameter (0.315" / 8.00mm), and maximum seated height (0.512" / 13.00mm). Through-hole mounting footprints are identical.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the RZW331M1CBK-0811S and 16YXF330MEFC8X11.5 are ROHS3 compliant.

Q: Which part should be selected for high-ripple-current applications?

A: The RZW331M1CBK-0811S is the appropriate selection for applications requiring high ripple current performance, as it provides 640 mA ripple current capability at 100 kHz compared to 400 mA for the substitute part.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 105°C with a rated lifetime of 7000 hours at 105°C.
