Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94HAB16 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a component to function as a direct substitute:

• Hexadecimal circuit configuration (16-position rotary mechanism)
• 100mA current rating at 50VDC voltage specification
• Rotary tool-actuated mechanism with flush, recessed actuator level
• Through-hole mounting with PC pin termination
• 0.100" (2.54mm) pitch spacing
• 0.225" (5.72mm) height above board
• Sealed construction with gold-plated copper alloy contacts
• Operating temperature range of -40°C to 85°C
• Mechanical life rating of 10,000 cycles

Substitute parts must maintain identical electrical performance, physical footprint, and environmental specifications to ensure direct interchangeability without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The 94HAB16T serves as a direct electrical and mechanical equivalent to the obsolete 94HAB16. Both components are manufactured by Grayhill Inc. within the 94H series and maintain identical specifications across all critical functional parameters.

The primary distinction between these parts is product status and packaging configuration. The 94HAB16 is classified as obsolete, while the 94HAB16T maintains active production status. This status difference ensures long-term component availability and supply chain continuity for new designs and production requirements.

Both components satisfy ROHS3 compliance requirements and carry REACH unaffected status, confirming regulatory alignment for industrial and commercial applications. The identical electrical ratings, mechanical life specifications, and environmental operating ranges ensure functional interchangeability without modification to circuit design or board layout.

For applications currently utilizing the 94HAB16, transition to the 94HAB16T is supported by complete parameter equivalence. The only consideration is packaging format: the 94HAB16T is supplied in tube packaging, whereas the original part may have been supplied in alternative packaging configurations.
