Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD16RM0CK is determined by strict equivalence across the following critical parameters:

• Circuit configuration: Hexadecimal (16-position)
• Electrical specifications: 0.4VA at 20VAC/DC
• Mechanical interface: Through-hole mounting, 0.100" pitch
• Actuator mechanism: Rotary for tool actuation
• Contact system: Copper alloy with gold finish
• Environmental rating: -25°C to 85°C operating range
• Mechanical and electrical life: 20,000 steps minimum

The CD16RM0CB qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The CD16RM0CB is the direct substitute for the obsolete CD16RM0CK. Both components share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit design and PCB layout.

The CD16RM0CB offers two significant advantages: active product status ensures ongoing availability and manufacturer support, and ROHS3 compliance satisfies regulatory requirements for new designs and applications subject to RoHS directives. The CD16RM0CK, classified as RoHS non-compliant, is unsuitable for applications requiring regulatory compliance.

For new designs, the CD16RM0CB is the appropriate selection. For legacy system maintenance or field replacement of existing CD16RM0CK installations, the CD16RM0CB provides full functional compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are CD16RM0CK and CD16RM0CB electrically interchangeable?

A: Yes. Both components operate at 0.4VA, 20VAC/DC with identical 16-position hexadecimal configuration, contact materials, and electrical life ratings of 20,000 steps.

Q: What is the primary reason to substitute CD16RM0CK with CD16RM0CB?

A: The CD16RM0CK is obsolete. The CD16RM0CB is an active product with guaranteed supply availability. Additionally, CD16RM0CB meets ROHS3 compliance, while CD16RM0CK does not.

Q: Will CD16RM0CB fit the same PCB footprint as CD16RM0CK?

A: Yes. Both components have identical through-hole mounting specifications: 0.100" pitch, 0.168" height above board, and 0.315" length. No PCB redesign is required.

Q: Does packaging differ between these parts?

A: Yes. CD16RM0CK is supplied in bulk packaging, while CD16RM0CB is supplied in tube packaging. This does not affect component functionality or performance.

Q: Can CD16RM0CK be used in new designs?

A: No. The obsolete status and RoHS non-compliance of CD16RM0CK make it unsuitable for new product development. CD16RM0CB is the required selection for new designs.
