Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD16CM0CB is determined by electrical and mechanical compatibility across the following critical parameters:

• Circuit configuration (Hexadecimal Complement)
• Number of positions (16)
• Electrical ratings (0.4VA, 20VAC/DC)
• Actuator type and actuation method (Rotary for Tool)
• Contact material and finish (Copper Alloy, Gold)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life (20,000 Steps)
• Compliance certifications (ROHS3, REACH Unaffected)

The primary difference between the main part and its substitute lies in the mounting technology and termination style. The CD16CM0CB uses through-hole mounting with PC pins, while the substitute CD16CM0SB uses surface-mount technology with gull-wing termination. Both parts maintain identical electrical performance, circuit logic, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CD16CM0CB and CD16CM0SB are active production parts from C&K with identical electrical specifications and compliance certifications. Selection between these parts is determined by PCB assembly technology and design requirements.

The CD16CM0CB through-hole variant is suitable for applications using traditional wave soldering or manual assembly processes, or where mechanical robustness and rework accessibility are prioritized. The CD16CM0SB surface-mount variant is appropriate for high-volume automated assembly lines and designs requiring compact board layouts.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications. The identical mechanical life (20,000 steps) and electrical life (20,000 steps) ratings confirm functional equivalence for configuration and control applications.

Frequently Asked Questions (FAQ)

Q: Can CD16CM0SB replace CD16CM0CB in an existing design?

A: Electrical and functional replacement is possible only if the PCB design accommodates surface-mount technology. The CD16CM0SB requires gull-wing footprint pads instead of through-hole vias. PCB layout redesign is necessary.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts operate at 0.4VA, 20VAC/DC with identical circuit logic (Hexadecimal Complement, 16 positions), contact materials, and environmental ratings.

Q: What is the difference in mounting technology?

A: CD16CM0CB uses through-hole PC pins for insertion into plated vias. CD16CM0SB uses surface-mount gull-wing leads soldered directly to PCB pads. These are mutually exclusive mounting methods.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the mechanical life expectancy?

A: Both parts are rated for 20,000 mechanical steps and 20,000 electrical steps, suitable for configuration applications with periodic adjustment.

Q: Are there inventory considerations for substitution?

A: CD16CM0SB has higher current inventory (4,963 pcs) compared to CD16CM0CB (1,077 pcs). Availability may influence selection for high-volume production.
