Substitute Part Grouping Explanation

The 94HAB08WT qualifies as a direct substitute for the 94HAB08W based on identical electrical and mechanical parameters. Substitution criteria are determined by the following parameters:

• Circuit Configuration: Both parts are octal configuration
• Number of Positions: Both provide 8 positions
• Current Rating: Both rated at 100mA
• Voltage Rating: Both rated at 50VDC
• Actuator Type: Both feature rotary tool actuator
• Mounting Type: Both are surface mount
• Termination Style: Both use gull wing termination
• Pitch: Both maintain 0.100" (2.54mm) pitch
• Height Above Board: Both measure 0.225" (5.72mm)
• Contact Material and Finish: Both use copper alloy with gold plating
• Operating Temperature Range: Both operate -40°C to 85°C
• Mechanical Life: Both rated for 10,000 cycles
• Sealed and Washable Features: Both are sealed and washable

The primary distinction between these parts is product status and packaging. The 94HAB08W is obsolete, while the 94HAB08WT maintains active product status with tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The 94HAB08WT is the appropriate selection for applications currently using or specifying the 94HAB08W. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 94HAB08WT offers the advantage of active product status, ensuring continued availability and manufacturing support. For new designs and production continuity, the 94HAB08WT should be specified in place of the obsolete 94HAB08W. Both parts maintain identical electrical performance, mechanical characteristics, and environmental ratings, ensuring functional equivalence in all applications.

Frequently Asked Questions (FAQ)

Q: Can the 94HAB08WT directly replace the 94HAB08W in existing designs?
