Grayhill 94HAB08 Rotary DIP Switch Octal - Equivalent & Substitute Parts

Part Overview

The Grayhill 94HAB08 is an octal rotary DIP switch designed for through-hole mounting applications requiring tool actuation. This component features 8 positions with a 100mA current rating at 50VDC, sealed construction, and gold-plated copper alloy contacts. The 94HAB08 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The substitute part 94HAB08T provides functional continuity with identical electrical and mechanical specifications while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 94HAB08 with the 94HAB08T is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications in the following key areas:

• Circuit Configuration: Both are octal (8-position) switches
• Electrical Ratings: 100mA current and 50VDC voltage ratings are identical
• Actuator Mechanism: Both use rotary tool actuation with flush, recessed actuator level
• Contact System: Copper alloy contacts with gold finish in both parts
• Physical Dimensions: Height above board (0.225"), length (0.390"), and pitch (0.100") are identical
• Mounting and Termination: Through-hole mounting with PC pin termination in both parts
• Environmental Specifications: Operating temperature range (-40°C to 85°C) and mechanical life (10,000 cycles) are identical
• Compliance: Both parts are ROHS3 compliant with MSL 1 rating

The primary distinction is product status: 94HAB08 is obsolete while 94HAB08T is active. The secondary distinction is packaging: 94HAB08T is supplied in tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The 94HAB08T is the direct active equivalent for the obsolete 94HAB08. Selection of 94HAB08T is appropriate for all applications currently using or specifying the 94HAB08 due to complete electrical and mechanical parameter equivalence.

Product Status Consideration: The 94HAB08 is obsolete. The 94HAB08T maintains active product status with Grayhill Inc., ensuring continued availability and supply chain reliability for new designs and production continuity.

Compliance Alignment: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 rating. No compliance-related design modifications are required when transitioning from 94HAB08 to 94HAB08T.

Packaging Difference: The 94HAB08T is supplied in tube packaging, whereas the 94HAB08 was supplied in bulk packaging. This packaging difference does not affect electrical or mechanical performance and is a standard industry practice for active product lines.

Frequently Asked Questions (FAQ)

Q: Can the 94HAB08T directly replace the 94HAB08 in existing designs?
