• Active Product Status: The ATC-15 is currently in active production with confirmed inventory availability (754 pcs new original in stock), providing reliable long-term sourcing
• Electrical Specifications: The 15 A current rating and 32 V DC voltage rating of the ATC-15 align with the functional requirements of the AT-15 specification
• Package Compatibility: The ATC-15 utilizes the standard Blade, ATO/ATC package format, compatible with existing holder assemblies

Frequently Asked Questions (FAQ)

Q: Why is the AT-15 no longer available? A: The AT-15 is classified as obsolete by the manufacturer. The ATC-15 has been designated as the active replacement, offering equivalent electrical and mechanical specifications with current production support.

Q: What are the key compatibility factors between AT-15 and ATC-15? A: Both parts share the same 15 A current rating, blade fuse package type (ATO/ATC), manufacturer origin, and regulatory compliance status. The ATC-15 specifies 32 V DC voltage rating and fast-blow response time, meeting the functional requirements of the original AT-15.

Q: Can the ATC-15 be used as a direct replacement? A: The ATC-15 is the manufacturer-recommended substitute. Both parts utilize the same blade fuse holder interface and share identical electrical protection characteristics. The ATC-15 is available in bulk packaging and is currently in active production.

Q: Are there any compliance differences between the two parts? A: No. Both the AT-15 and ATC-15 maintain RoHS compliance and share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, ensuring regulatory alignment for import, export, and use applications.

Q: What is the physical size of the ATC-15? A: The ATC-15 measures 0.760" L x 0.207" W x 0.492" H (19.30mm x 5.25mm x 12.50mm), conforming to standard automotive blade fuse dimensions.
