Substitute Part Grouping Explanation

Substitution of the 170M3810 is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitutes:

• Current Rating: 63A (exact match required)
• Voltage Rating: 700VAC (exact match required)
• Fuse Type: Square (exact match required)
• Package / Case: Rectangular, Blade (exact match required)
• Physical Dimensions: 2.717" L x 1.772" W x 2.283" H (exact match required)
• Breaking Capacity: 200kA (exact match required)
• Melting I²t: 120 (exact match required)
• Approval Certifications: CSA, UR (must be maintained)

The 170M3810D meets all substitution criteria as a direct equivalent. The primary distinction is product status: 170M3810 is obsolete, while 170M3810D is active and available for procurement.
