5TTP 5 Equivalent & Substitute Parts

Part Overview

The 5TTP 5 is a 5A 125VAC glass cartridge fuse with slow-blow response characteristics, designed for through-hole mounting in 5mm x 20mm form factor applications. This part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and component procurement. The substitute part maintains identical electrical and mechanical specifications while offering improved compliance status and active product availability.

Key Parameters

Substitute Part Grouping Explanation

The 5TTP 5-R qualifies as a direct substitute for the 5TTP 5 based on the following critical parameters:

• Current Rating: Identical at 5 A
• Voltage Rating (AC): Identical at 125 V
• Fuse Type: Identical cartridge glass construction
• Response Time: Identical slow-blow characteristic
• Package / Case: Identical 5mm x 20mm (Axial) form factor
• Mounting Type: Identical through-hole configuration
• Breaking Capacity: Identical 10 kA rating
• Melting I²t: Identical value of 157
• Operating Temperature Range: Identical -55°C to 125°C
• DC Cold Resistance: Identical 0.02 Ohms

The substitution is based on complete electrical and mechanical parameter equivalence. Both parts are manufactured by Bel Fuse Inc. within the same 5TTP series.

Parameter Comparison

Engineering Selection Recommendations

The 5TTP 5-R is the appropriate substitute for the obsolete 5TTP 5. Selection is based on:

• Complete electrical parameter equivalence across all critical specifications
• Identical mechanical form factor and mounting configuration
