Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94HBB16RA is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: Hexadecimal (16-position)
• Current rating: 100mA
• Voltage rating: 50VDC
• Actuator type: Rotary with shaft
• Mounting configuration: Through hole, right angle
• Pitch spacing: 0.100" (2.54mm)
• Contact material and finish: Copper alloy with gold plating
• Operating temperature range: -40°C to 85°C
• Mechanical life: 10,000 cycles
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part 94HBB16RAT maintains identical electrical and mechanical specifications to the main part. The primary distinction is product status classification and packaging format. The 94HBB16RAT is classified as active product status, ensuring ongoing manufacturer support and availability. Packaging differs between the two parts, with the substitute supplied in tube format compared to the main part's standard packaging.

Parameter Comparison

Engineering Selection Recommendations

The 94HBB16RAT is a direct functional equivalent to the 94HBB16RA. Both components share identical electrical ratings, mechanical specifications, and compliance certifications. The primary distinction is product lifecycle status: the 94HBB16RA is classified as obsolete, while the 94HBB16RAT maintains active product status with Grayhill Inc.

For new designs or ongoing production requiring hexadecimal rotary DIP switches with 100mA/50VDC ratings and through-hole right-angle mounting, the 94HBB16RAT is the appropriate selection. This part ensures manufacturer support, documented availability, and compliance with ROHS3 and REACH requirements.

For existing applications currently using the 94HBB16RA, direct substitution with the 94HBB16RAT is electrically and mechanically compatible. No circuit modifications or PCB layout changes are required. Packaging format differs (tube versus standard), which may affect procurement and handling procedures but does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 94HBB16RAT directly replace the 94HBB16RA in existing designs?

A: Yes. The 94HBB16RAT is electrically and mechanically identical to the 94HBB16RA. All electrical parameters, mechanical dimensions, mounting configuration, and compliance certifications are equivalent. Direct substitution requires no circuit or PCB modifications.

Q: What is the difference between the 94HBB16RA and 94HBB16RAT?

A: The components are functionally identical. The 94HBB16RA is classified as obsolete product status, while the 94HBB16RAT is active. The 94HBB16RAT is supplied in tube packaging, whereas the 94HBB16RA uses standard packaging. These differences do not affect electrical or mechanical performance.

Q: Why is the 94HBB16RA classified as obsolete?

A: Product status classifications reflect manufacturer lifecycle decisions. The obsolete designation indicates that Grayhill Inc. no longer actively produces or supports the 94HBB16RA. The 94HBB16RAT remains the active equivalent within the 94H series.

Q: Are there any compatibility concerns when substituting the 94HBB16RAT for the 94HBB16RA?

A: No compatibility concerns exist. Both parts maintain identical specifications across all critical parameters: 16-position hexadecimal configuration, 100mA current rating, 50VDC voltage rating, rotary shaft actuator, through-hole right-angle mounting, 0.100" pitch, copper alloy gold-plated contacts, -40°C to 85°C operating range, and 10,000-cycle mechanical life. ROHS3 and REACH compliance status is identical.

Q: Does packaging format affect component performance?

A: No. Packaging format (tube versus standard) affects procurement, storage, and handling procedures but does not impact electrical performance, mechanical specifications, or functional characteristics. The internal component design and specifications remain identical.

Q: What compliance certifications apply to both parts?

A: Both the 94HBB16RA and 94HBB16RAT are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (unlimited). Both parts carry EAR99 ECCN classification and HTSUS code 8536.50.9065.
