Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94HFB16WRT is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: Hexadecimal (16 positions)
• Current rating: 100mA
• Voltage rating: 50VDC
• Contact material and finish: Copper alloy with gold plating

Mechanical Equivalence Requirements:

• Actuator type: Rotary for tool actuation
• Mounting configuration: Surface mount with gull wing termination
• Pitch spacing: 0.100" (2.54mm)
• Height above board: 0.225" (5.72mm)
• Body material: Plastic construction

Compliance and Environmental Requirements:

• RoHS3 compliance
• Operating temperature range: -40°C to 85°C
• Mechanical life: 10,000 cycles minimum
• Sealed construction with washable capability

The primary variable among equivalent parts is packaging format (Tape & Reel versus Tube), which does not affect functional performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 94HAB16WT is a direct functional equivalent to the 94HFB16WRT. Both parts are manufactured by Grayhill Inc. within the 94H series and share identical electrical ratings, mechanical dimensions, contact specifications, and environmental compliance certifications.

Selection between these parts should be based on packaging and inventory requirements:

94HFB16WRT is supplied in Tape & Reel format, suitable for automated assembly processes and high-volume production environments.

94HAB16WT is supplied in Tube packaging, suitable for manual assembly, lower-volume applications, or when tape-and-reel packaging is not required.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical performance characteristics across all specified electrical and mechanical parameters. Product status is Active for both variants, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can 94HAB16WT be used as a direct replacement for 94HFB16WRT on a PCB assembly?

A: Yes. Both parts are electrically and mechanically identical. They feature the same gull wing termination, 0.100" pitch spacing, 0.225" height above board, and all electrical specifications. The only difference is packaging format (Tube versus Tape & Reel), which does not affect board-level performance or compatibility.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Tube packaging contains loose components and is typically used for manual assembly, lower-volume runs, or component storage. Both formats contain the same component with identical specifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 94HFB16WRT and 94HAB16WT are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on hexadecimal circuit configuration (16 positions), 100mA current rating, 50VDC voltage rating, copper alloy contacts with gold finish, and sealed construction. Any deviation from these parameters disqualifies a part as a direct substitute.

Q: Can these parts be used in applications requiring washable assembly processes?

A: Yes. Both parts feature sealed construction with washable capability, allowing use in manufacturing processes that include aqueous or semi-aqueous cleaning steps.

Q: What is the mechanical life specification for these rotary DIP switches?

A: Both parts are rated for 10,000 mechanical cycles, representing the number of complete rotational actuations the switch can withstand while maintaining specified electrical performance.
