Substitute Part Grouping Explanation

Substitution for the SH6R8M350ST is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Product category classification as aluminum electrolytic capacitor
• RoHS3 compliance requirement
• MSL rating compatibility (MSL 1 or equivalent)
• ECCN and HTSUS code alignment (EAR99, 8532.22.0020)
• Through-hole or radial mounting compatibility
• Active product status for ongoing availability

The identified substitute part, 400AX6.8MEFC8X10.8 from Rubycon, meets these substitution parameters. This part is classified as active product status, ensuring continued availability and supply chain support. Both parts share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Engineering Selection Recommendations

Substitution Basis:

The 400AX6.8MEFC8X10.8 from Rubycon qualifies as a functional substitute for the obsolete SH6R8M350ST based on the following engineering factors:

1. Regulatory Compliance: Both parts maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications, ensuring equivalent regulatory treatment for procurement and export purposes.

2. Product Availability: The substitute part holds active product status with significantly higher inventory availability (8980 Pcs vs. 805 Pcs), providing superior supply chain continuity and reducing obsolescence risk.

3. Component Category Alignment: Both parts are classified as aluminum electrolytic capacitors with radial, can-style packaging suitable for through-hole mounting applications.

4. Environmental Specifications: The substitute part operates within the -40°C to 105°C temperature range with 2000-hour lifetime rating at 105°C, supporting general industrial and commercial applications.

Selection of the substitute part is appropriate when the original SH6R8M350ST inventory is depleted or when long-term supply assurance is required for production continuity.

Frequently Asked Questions (FAQ)

Q1: What makes the 400AX6.8MEFC8X10.8 a suitable substitute for the SH6R8M350ST?

A: Both parts are aluminum electrolytic capacitors with ROHS3 compliance and identical regulatory classifications (ECCN EAR99, HTSUS 8532.22.0020). The substitute part is active product status, ensuring ongoing availability compared to the obsolete main part.

Q2: Are there electrical parameter differences between these parts?

A: The substitute part specifies 6.8 µF capacitance at 400 V rated voltage with ±20% tolerance. Detailed electrical specifications for the main part were not provided in the input parameters. Electrical compatibility must be verified against circuit design requirements.

Q3: What is the physical form factor of the substitute part?

A: The 400AX6.8MEFC8X10.8 is a radial, can-style aluminum electrolytic capacitor with through-hole mounting. Lead spacing is 0.138" (3.50mm), body diameter is 0.315" (8.00mm), and maximum seated height is 0.484" (12.30mm).

Q4: Does the substitute part have the same moisture sensitivity level?

A: The main part has MSL rating of 1 (Unlimited). The substitute part lists MSL as Not Applicable, which is standard for through-hole radial capacitors. This indicates equivalent or superior moisture handling characteristics.

Q5: What is the operational lifetime of the substitute part?

A: The 400AX6.8MEFC8X10.8 is rated for 2000 hours at 105°C operating temperature, with operating range of -40°C to 105°C. This specification supports general industrial applications requiring standard electrolytic capacitor performance.

Q6: Is the substitute part suitable for direct PCB replacement?

A: The substitute part uses through-hole radial mounting with 0.138" (3.50mm) lead spacing. Direct replacement is possible if the original PCB layout accommodates radial, can-style through-hole components with these lead spacing dimensions.
