Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMXL-150 is limited to components that maintain strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Non-Negotiable):

• Current Rating: 150 A
• Voltage Rating - DC: 125 V
• Breaking Capacity @ Rated Voltage: 3 kA
• DC Cold Resistance: 0.00033 Ohms

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Bolt Mount
• Package / Case: Auto Link
• Physical Dimensions: 0.630" L x 0.472" W x 0.335" H (16.00 mm x 12.00 mm x 8.50 mm)

Compliance Parameters (Non-Negotiable):

• Approval Agency: cURus, UL
• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -40°C to 105°C

Only components matching all parameters across these three categories are classified as direct substitutes. Series designation differences (AMXL versus AMX) do not affect substitution eligibility when all electrical, mechanical, and compliance specifications are identical.
