Substitute Part Grouping Explanation

Substitute parts for the VZH331M1CTR-0810S are identified based on strict parametric equivalence. The following criteria determine substitution validity:

Primary Equivalence Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 5000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.315" Dia (8.00mm) and Height 0.413" (10.50mm) (exact match required)
• Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm) (exact match required)

Secondary Compatibility Parameters:

• Impedance: 170 mOhms (equivalent or lower acceptable)
• Ripple Current @ 100 kHz: 450 mA minimum (equal or higher acceptable)
• RoHS Compliance: ROHS3 Compliant (required)

The substitute part 865060353008 (Würth Elektronik WCAP-ASLL series) meets all primary equivalence parameters and demonstrates superior performance in secondary parameters, including higher ripple current capability (550 mA @ 100 kHz) and improved moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can 865060353008 be used as a direct replacement for VZH331M1CTR-0810S in existing PCB designs?

A: Yes. The 865060353008 is a direct parametric equivalent with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), physical dimensions (8.00mm diameter, 10.50mm height), and surface mount land size (8.30mm x 8.30mm). No PCB layout modifications are required.

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

A: The primary differences are manufacturer (SURGE versus Würth Elektronik) and ripple current performance. The 865060353008 provides higher ripple current capability at 100 kHz (550 mA versus 450 mA), representing a 22% performance improvement. The 865060353008 also specifies a superior moisture sensitivity level (MSL 1 - Unlimited). All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for high-frequency applications?

A: Both parts are rated for operation at 100 kHz with specified ripple current values. The 865060353008 demonstrates higher ripple current capacity (550 mA @ 100 kHz), making it more suitable for applications requiring sustained high-frequency ripple current. The VZH331M1CTR-0810S (450 mA @ 100 kHz) is suitable for standard high-frequency applications within its specified rating.

Q: Do these parts require different PCB footprints?

A: No. Both parts use identical surface mount land sizes (0.327" L x 0.327" W or 8.30mm x 8.30mm) and are packaged in Radial, Can - SMD format. PCB footprints are interchangeable.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates that actual capacitance values will fall within the range of 264 µF to 396 µF. Both parts share this tolerance specification, ensuring equivalent performance characteristics in applications where this tolerance level is acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes. Both VZH331M1CTR-0810S and 865060353008 are certified RoHS3 compliant, meeting regulatory requirements for hazardous substance restrictions in electronic components.

Q: What is the operational lifetime of these capacitors?

A: Both parts are rated for 5000 hours of operation at 105°C. This specification defines the expected service life under maximum temperature conditions. Actual operational lifetime extends significantly when operating at lower temperatures.

Q: Can these parts be used in applications requiring operation below -55°C or above 105°C?

A: No. Both parts are specified for operation within the -55°C to 105°C temperature range. Use outside this range is not supported and may result in component failure or performance degradation.
