Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94HBB16 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (hexadecimal/16-position), current rating (100mA), and voltage rating (50VDC) must be identical. These parameters define the electrical load capacity and switching capability of the component.

Mechanical Parameters: Actuator type (rotary with shaft), mounting method (through-hole), pitch spacing (0.100"), and height above board (0.495") must match to ensure physical compatibility with existing PCB layouts and mechanical assemblies.

Environmental & Reliability Parameters: Operating temperature range (-40°C to 85°C), sealed construction, and mechanical life rating (10,000 cycles) establish functional equivalence for the intended application environment.

Material & Finish Specifications: Contact material (copper alloy) and contact finish (gold) ensure electrical performance and long-term reliability characteristics.

Compliance Standards: RoHS3 compliance status must be maintained for regulatory equivalence.

The 94HBB16T qualifies as a direct substitute based on complete alignment with all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The 94HBB16T is the direct functional equivalent of the 94HBB16 and qualifies as a complete substitute for all electrical, mechanical, and environmental applications.

Product Status Consideration: The 94HBB16 is classified as Obsolete, while the 94HBB16T maintains Active product status. This distinction is significant for long-term supply chain planning and component lifecycle management. Selection of the 94HBB16T ensures access to current manufacturing processes, quality assurance protocols, and ongoing supplier support.

Compliance & Certification Equivalence: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and export classification (EAR99). No regulatory or compliance barriers exist for substitution.

Packaging Consideration: The 94HBB16T is supplied in Tube packaging, whereas the original 94HBB16 was supplied in bulk packaging. Tube packaging provides improved component protection during storage and handling, with no impact on electrical or mechanical performance.

Inventory & Availability: The 94HBB16T demonstrates significantly higher inventory availability (5,666 pieces in stock) compared to the obsolete 94HBB16 (874 pieces in stock), supporting immediate procurement for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 94HBB16T be used as a direct replacement for the 94HBB16 in existing designs?

A: Yes. The 94HBB16T is electrically and mechanically identical to the 94HBB16 across all specified parameters. No design modifications are required.
