Grayhill 94HAB10 Rotary DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 94HAB10 is a rotary DIP switch featuring BCD encoding with 10 positions, designed for through-hole mounting applications requiring tool actuation. This component operates at 100mA and 50VDC, with sealed construction and gold-plated copper alloy contacts. The 94HAB10 is classified as obsolete, necessitating identification of active equivalent parts to ensure continued design support and procurement availability. The substitute part 94HAB10T maintains identical electrical and mechanical specifications while offering active product status and improved inventory availability.

Key Parameters

Substitute Part Grouping Explanation

The 94HAB10T qualifies as a direct equivalent substitute based on identical electrical and mechanical parameters. Substitution logic is determined by the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Circuit encoding: BCD
• Position count: 10
• Current rating: 100mA
• Voltage rating: 50VDC

Mechanical Parameters (Must Match Exactly):

• Actuator type: Rotary for Tool
• Mounting method: Through Hole
• Pin pitch: 0.100" (2.54mm)
• Height above board: 0.225" (5.72mm)
• Contact material and finish: Copper Alloy with Gold plating

Environmental & Compliance Parameters (Must Match or Exceed):

• Operating temperature range: -40°C to 85°C
• Mechanical life: 10,000 cycles
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The 94HAB10T maintains 100% parameter alignment with the 94HAB10, differing only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The 94HAB10T is the direct equivalent substitute for the obsolete 94HAB10. Selection is based on the following engineering criteria:

Product Status Consideration: The 94HAB10 is classified as obsolete, creating supply chain risk for new designs and production continuity. The 94HAB10T maintains active product status with Grayhill Inc., ensuring long-term availability and manufacturing support.

Compliance Alignment: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, satisfying regulatory requirements without modification to procurement or documentation procedures.

Functional Equivalence: All electrical parameters (BCD encoding, 10-position configuration, 100mA current rating, 50VDC voltage rating) and mechanical parameters (through-hole mounting, 0.100" pitch, 0.225" height, rotary tool actuator) are identical, enabling direct PCB footprint compatibility and circuit functionality without design revision.

Inventory and Packaging: The 94HAB10T offers significantly higher inventory availability (3,516 pieces vs. 725 pieces) and tube packaging, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 94HAB10T be used as a direct replacement for the 94HAB10 without PCB modification?

A: Yes. The 94HAB10T is electrically and mechanically identical to the 94HAB10. Pin pitch (0.100"), height above board (0.225"), mounting type (through-hole), and all electrical specifications match exactly. No PCB layout changes are required.

Q: What is the difference between the 94HAB10 and 94HAB10T?

A: The primary differences are product status and packaging. The 94HAB10 is obsolete with standard packaging, while the 94HAB10T is active with tube packaging. All functional and electrical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, EAR99 export classification, and moisture sensitivity level (MSL 1). Regulatory documentation and procurement standards remain unchanged.

Q: What is the mechanical life specification, and does it apply to both parts?

A: Both parts are rated for 10,000 mechanical cycles. This specification defines the expected operational life under normal switching conditions and applies identically to both the 94HAB10 and 94HAB10T.

Q: Does the tube packaging of the 94HAB10T affect compatibility?

A: No. Tube packaging is a distribution format only and does not affect electrical or mechanical compatibility. The component itself remains identical. Tube packaging may provide advantages for automated assembly processes.

Q: What operating temperature range is supported?

A: Both parts operate across -40°C to 85°C. This range applies to all electrical and mechanical specifications without derating.

Q: Is the 94HAB10T washable like the original part?

A: Yes. The 94HAB10T maintains the sealed construction and washable feature of the 94HAB10, supporting standard PCB cleaning processes.
