Substitute Part Grouping Explanation

Substitution eligibility for the 94HAB16RA is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (hexadecimal), position count (16), current rating (100mA), and voltage rating (50VDC) must be identical. These parameters define the functional electrical behavior and load-handling capability of the switch.

Mechanical Parameters: Actuator type (rotary for tool), mounting configuration (through-hole, right-angle), and physical dimensions (height, pitch, length) must match to ensure PCB compatibility and mechanical fit without redesign.

Environmental & Compliance Parameters: Operating temperature range (-40°C to 85°C), sealed construction, washability, RoHS3 compliance, and REACH status must be maintained to preserve system reliability and regulatory conformance.

Contact Specifications: Copper alloy contact material with gold finish ensures consistent electrical performance and corrosion resistance across substitute parts.

Substitute parts within this grouping differ only in packaging format and product status, not in functional or mechanical specifications.

Engineering Selection Recommendations

The 94HAB16RAT is a direct functional equivalent to the 94HAB16RA. Both parts are manufactured by Grayhill Inc. within the 94H series and share identical electrical, mechanical, and environmental specifications.

Primary Advantage: The 94HAB16RAT carries an active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The 94HAB16RA is obsolete and subject to inventory depletion.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current and future applications.

Packaging Consideration: The 94HAB16RAT is supplied in tube packaging, which is standard for active production components. The original 94HAB16RA packaging format is not specified in available data. Tube packaging does not affect functional performance or PCB integration.

Design Integration: No PCB layout modifications, schematic changes, or mechanical redesign are required when transitioning from 94HAB16RA to 94HAB16RAT. Direct substitution is supported at the component level.

Frequently Asked Questions (FAQ)

Q: Can the 94HAB16RAT be used as a direct replacement for the 94HAB16RA without PCB modifications?

A: Yes. The 94HAB16RAT is electrically and mechanically identical to the 94HAB16RA. All critical parameters including pin pitch (0.100"), height (0.400"), electrical ratings (100mA, 50VDC), and functional specifications match exactly. No PCB layout changes are required.

Q: What is the difference between the 94HAB16RA and 94HAB16RAT?

A: The primary differences are product status and packaging. The 94HAB16RA is obsolete; the 94HAB16RAT is active production. The 94HAB16RAT is supplied in tube packaging. All functional and mechanical specifications are identical.

Q: Why is the 94HAB16RA listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number. The 94HAB16RAT represents the current active equivalent within the same product family.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate at 100mA, 50VDC with identical contact materials (copper alloy, gold finish), temperature range (-40°C to 85°C), and mechanical life (10,000 cycles). Electrical performance is equivalent.

Q: Does tube packaging affect component reliability or performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tube packaging is a standard distribution method for active production components and provides equivalent protection during storage and handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 94HAB16RA and 94HAB16RAT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I mix 94HAB16RA and 94HAB16RAT components in the same production batch?

A: Yes. Since both parts are functionally and mechanically identical, they can be used interchangeably within the same assembly without affecting performance or reliability.
