Parameter Comparison

Engineering Selection Recommendations

The 3FTH98020 is the direct substitute for the obsolete 3FTL68020. Both components are manufactured by MEC Switches within the Multimec® 3 series and share identical electrical and mechanical specifications across all critical parameters.

The 3FTH98020 offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended operating temperature range (-40°C to 160°C versus -40°C to 115°C) provides broader thermal operating envelope
• ROHS3 compliance maintained
• Identical contact rating, circuit configuration, and mechanical characteristics
• Through-hole PCB mounting compatibility preserved
• IP67 ingress protection and sealed construction maintained

For applications operating within the original temperature specification of -40°C to 115°C, the 3FTH98020 provides direct functional and physical replacement. For applications requiring extended temperature operation up to 160°C, the 3FTH98020 offers enhanced thermal capability.

Frequently Asked Questions (FAQ)

Q: Can the 3FTH98020 directly replace the 3FTL68020 in existing designs?
