Substitute Part Grouping Explanation

Substitution eligibility for the 516D106M350PR6AE3 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 10 µF (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Axial, Can (exact match required)

Allowable Variation Parameters:

• Voltage rating: Substitute must be rated at 350 V or higher
• Tolerance: Substitute tolerance must be ±20% or tighter
• Operating temperature range: Substitute must support -25°C to 85°C minimum
• Lifetime rating: Substitute must provide 2000 hours at 85°C or greater
• RoHS compliance: Substitute must maintain ROHS3 compliance

The substitute part 106TTA450M meets all mandatory matching criteria and exceeds allowable variation parameters, qualifying it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 106TTA450M qualifies as a direct substitute for the obsolete 516D106M350PR6AE3 based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. The 450 V rating of the substitute provides a 100 V margin above the 350 V requirement, enhancing circuit reliability. Capacitance, tolerance, and temperature ratings are identical. Ripple current handling is superior in the substitute part.

Mechanical Compatibility: Both parts are axial, can-type aluminum electrolytic capacitors with through-hole mounting. Physical dimensions are comparable, with the substitute being marginally smaller (0.492" diameter vs. 0.512", and 0.984" length vs. 1.024"). This dimensional difference does not preclude direct substitution in standard through-hole PCB layouts.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Product Status: The substitute part 106TTA450M carries active product status with 5050 units in stock, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 106TTA450M be used as a direct replacement for the 516D106M350PR6AE3 in existing designs?

A: Yes. The substitute part matches all mandatory electrical and mechanical parameters: 10 µF capacitance, ±20% tolerance, polar configuration, through-hole mounting, and axial can package. The higher 450 V rating provides additional safety margin.

Q: What is the significance of the voltage rating difference (350 V vs. 450 V)?

A: The substitute's 450 V rating exceeds the original 350 V specification. In circuit applications, this provides a 100 V safety margin and does not create incompatibility. The capacitor will function identically in circuits designed for 350 V operation.

Q: Are the physical dimensions of the substitute compatible with existing PCB layouts?

A: The substitute dimensions (0.492" Dia x 0.984" L) are slightly smaller than the original (0.512" Dia x 1.024" L). This dimensional reduction is compatible with standard through-hole PCB designs and does not require layout modifications.

Q: Does the substitute part meet the same reliability specifications?

A: Yes. Both parts are rated for 2000 hours at 85°C and support the identical operating temperature range of -25°C to 85°C. The substitute's ripple current rating (90 mA @ 120 Hz) exceeds the original (85 mA @ 120 Hz), indicating equivalent or superior reliability.

Q: What is the ESR difference between the two parts?

A: The original part does not specify ESR. The substitute provides 41.447 Ohm ESR at 120 Hz. This specification indicates low equivalent series resistance, which is beneficial for ripple current handling and thermal performance in general-purpose applications.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance differences exist between the main part and substitute.

Q: What is the inventory status of the substitute part?

A: The 106TTA450M is in active production with 5050 units currently in stock, providing reliable long-term availability for production and replacement applications.
