CD10RM0CK Equivalent & Substitute Parts

Part Overview

The CD10RM0CK is a rotary DIP switch manufactured by C&K, designed for tool actuator applications with BCD circuit configuration. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design requirements. The CD10RM0CK provides 10-position switching capability with 0.4VA current rating at 20VAC/DC, suitable for applications requiring sealed, washable switching mechanisms.

Key Parameters

Substitute Part Grouping Explanation

The CD10RM0CB qualifies as a direct substitute for the CD10RM0CK based on the following critical parameters:

• Circuit configuration: Both use BCD circuit type
• Position count: Both provide 10-position switching
• Electrical ratings: Identical 0.4VA at 20VAC/DC
• Actuator specification: Both feature rotary tool actuator with flush, recessed level
• Mechanical interface: Matching through-hole mounting, 0.100" pitch, PC pin termination
• Physical dimensions: Identical height (0.168"), length (0.315"), and body material (PPS)
• Contact system: Copper alloy with gold finish in both parts
• Environmental performance: Matching operating temperature range (-25°C to 85°C) and life ratings (20,000 steps mechanical and electrical)

The primary distinction is product status: CD10RM0CK is obsolete while CD10RM0CB is active, with improved RoHS compliance (ROHS3 Compliant versus non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The CD10RM0CB is the appropriate selection for new designs and procurement activities. This part maintains complete electrical and mechanical compatibility with the obsolete CD10RM0CK while offering active product status and ROHS3 compliance. The transition from non-compliant to ROHS3 compliant status aligns with current regulatory requirements for electronic component manufacturing and distribution.

Both parts share identical functional specifications, dimensional characteristics, and performance ratings, ensuring direct substitution without circuit redesign or mechanical modification. The CD10RM0CB's active status provides assured long-term availability and supply chain stability compared to the obsolete CD10RM0CK.

Frequently Asked Questions (FAQ)

Q: Can CD10RM0CB replace CD10RM0CK in existing designs?

A: Yes. The CD10RM0CB provides identical electrical ratings (0.4VA at 20VAC/DC), mechanical configuration (10-position BCD rotary through-hole), and physical dimensions (0.168" height, 0.315" length). No circuit modifications or PCB layout changes are required.

Q: What is the difference in packaging between these parts?

A: CD10RM0CK is supplied with unspecified packaging (-), while CD10RM0CB is packaged in tubes. Tube packaging is standard for active production parts and does not affect component functionality or performance.

Q: Why is RoHS compliance different between these parts?

A: CD10RM0CK is RoHS non-compliant due to its obsolete status, while CD10RM0CB meets ROHS3 compliance standards. For applications subject to RoHS regulations or customer requirements, CD10RM0CB is the required selection.

Q: Are the mechanical life and electrical life ratings identical?

A: Yes. Both parts are rated for 20,000 steps of mechanical life and 20,000 steps of electrical life, providing equivalent durability and operational longevity.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -25°C to 85°C, supporting equivalent thermal performance in industrial and commercial applications.

Q: Are both parts washable?

A: Yes. Both CD10RM0CK and CD10RM0CB feature process-sealed construction and are washable, suitable for applications requiring cleaning or exposure to moisture.
