Substitute Part Grouping Explanation

Substitution of the 20C10X38SC is permissible with part number 002625011, also manufactured by Altech Corporation. The substitution is valid based on the following critical parameters:

• Current Rating: Both parts are rated for 20A
• Voltage Rating: The main part operates at 600VAC; the substitute operates at 600VAC/700VDC, providing equivalent or superior voltage capability
• Physical Form Factor: Both are cartridge fuses with 10x38mm dimensions, ensuring mechanical compatibility with existing fuse holders
• Manufacturer: Both parts are from Altech Corporation, ensuring consistent quality and performance standards

The substitute part 002625011 belongs to the CH 10x38 series and provides equivalent protection characteristics while offering dual voltage rating capability (600VAC/700VDC).

Parameter Comparison

Engineering Selection Recommendations

Selection between the main part 20C10X38SC and substitute 002625011 should be based on application voltage requirements and inventory availability:

• For 600VAC applications: Both parts are suitable. The 20C10X38SC is the primary specification; 002625011 serves as a direct substitute.
• For applications requiring DC capability: The 002625011 (600VAC/700VDC rating) provides additional operational flexibility beyond the main part specification.
• For inventory management: The main part has higher stock availability (924 units vs. 745 units). Selection should prioritize availability based on project timeline requirements.

Both parts maintain identical mechanical compatibility with standard 10x38mm fuse holders and provide equivalent 20A overcurrent protection performance.

Frequently Asked Questions (FAQ)

Q: Can 002625011 be used as a direct replacement for 20C10X38SC?

A: Yes. Both parts share identical current ratings (20A), voltage ratings (600VAC), and physical dimensions (10x38mm cartridge form factor). The substitute part offers additional 700VDC capability, making it suitable for the same 600VAC applications.

Q: What is the difference between the two part numbers?

A: The primary difference is the voltage rating specification. The 20C10X38SC is rated for 600VAC only, while 002625011 is rated for 600VAC/700VDC. Both deliver 20A protection in identical 10x38mm cartridge packages.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts are 10x38mm cartridge fuses and are mechanically compatible with standard fuse holders designed for this form factor.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For 600VAC-only circuits, either part is acceptable. For applications that may require DC operation or future flexibility, 002625011 provides broader voltage capability.

Q: Is there a difference in fuse response time or breaking capacity?

A: Both parts are classified as 5AG cartridge fuses from Altech Corporation. The provided specifications confirm identical current ratings and form factors. Detailed breaking capacity and response time characteristics are determined by the 5AG classification standard.
