Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATDR1 is determined by the following critical parameters:

• Current Rating: 1A (exact match required)
• Voltage Rating: 600V AC minimum (600V AC / 300V DC acceptable)
• Fuse Class: CC (Class CC cartridge fuse specification)
• Response Time: Slow Blow characteristic
• Package / Case: 5AG, 10mm x 38mm (Midget) form factor
• ECCN Classification: EAR99 (export control alignment)
• HTSUS Code: 8536.10.0040 (tariff classification alignment)

The LP-CC-1 substitute part meets all critical substitution criteria through matching current rating, voltage rating, fuse class, response time, physical dimensions, and regulatory classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ATDR1 and LP-CC-1 maintain active product status and share identical ECCN and HTSUS classifications, ensuring regulatory alignment for procurement and export purposes. The LP-CC-1 substitute offers ROHS3 compliance, which may be advantageous for applications subject to RoHS requirements, whereas the ATDR1 remains non-compliant. Both parts are available in production quantities. Selection between these parts should be based on specific application requirements regarding RoHS compliance status and supply chain availability. The LP-CC-1 is supplied in bulk packaging, while the ATDR1 is supplied in box packaging; packaging format should be evaluated against inventory management and handling requirements.

Frequently Asked Questions (FAQ)

Q: What makes LP-CC-1 a valid substitute for ATDR1?

A: The LP-CC-1 matches the ATDR1 across all critical electrical parameters: 1A current rating, 600V AC voltage rating, CC fuse class, and slow blow response time. Both parts share identical ECCN and HTSUS classifications and maintain active product status.

Q: Are there physical dimension differences between ATDR1 and LP-CC-1?

A: The LP-CC-1 is specified as 5AG, 10mm x 38mm (Midget) form factor. The ATDR1 physical dimensions are not provided in the available technical data. Verification of physical compatibility with the intended fuse holder or mounting application is necessary before substitution.

Q: What is the difference in RoHS compliance between these parts?

A: The ATDR1 is RoHS non-compliant, while the LP-CC-1 is ROHS3 compliant. Applications subject to RoHS directives should specify the LP-CC-1. Applications without RoHS requirements may use either part.

Q: Do both parts have the same breaking capacity?

A: Breaking capacity is specified for the LP-CC-1 as 200kA AC and 20kA DC at rated voltage. Breaking capacity for the ATDR1 is not provided in the available technical data. Breaking capacity should be verified against application requirements before substitution.

Q: What packaging differences exist between these parts?

A: The ATDR1 is supplied in box packaging with 1187 pieces in stock. The LP-CC-1 is supplied in bulk packaging with 1115 pieces in stock. Packaging format selection should align with inventory management and handling procedures.

Q: Can LP-CC-1 be used in applications requiring DC voltage?

A: The LP-CC-1 is rated for 300 VDC. Applications requiring DC operation at this voltage level may use the LP-CC-1. The ATDR1 DC voltage rating is not specified and should be verified before DC application use.
