Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity ALCOSWITCH 1825007-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: BCD Complement
• Number of positions: 10
• Current rating: 0.4VA
• Voltage rating: 20VAC/DC
• Actuator type: Rotary for Tool
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Pitch: 0.100" (2.54mm)
• Contact material: Copper Alloy
• Contact finish: Gold

The C&K CD10CM0SB meets all mandatory electrical and mechanical parameters required for direct substitution. Both components share identical circuit logic, switching capacity, voltage/current ratings, and physical mounting characteristics. Differences in height above board, length, and mechanical/electrical life ratings do not preclude substitution, as these represent performance enhancements or design refinements within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

The C&K CD10CM0SB is a direct functional equivalent to the TE Connectivity ALCOSWITCH 1825007-3 for applications requiring BCD complement 10-position rotary DIP switches with 0.4VA/20VAC/DC ratings and surface mount gull wing termination.

Product Status Consideration: The TE Connectivity 1825007-3 is classified as obsolete, while the C&K CD10CM0SB maintains active production status. This distinction is significant for long-term supply chain planning and component availability.

Compliance and Certification: The C&K CD10CM0SB carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in regulated markets. Both components share identical ECCN and HTSUS classifications, indicating equivalent export control and tariff treatment.

Physical Dimensions: The C&K CD10CM0SB features reduced height above board (0.168" versus 0.291") and shorter overall length (0.315" versus 0.394"), providing potential advantages for space-constrained PCB layouts. These dimensional differences do not affect electrical compatibility but may require PCB footprint verification for existing designs.

Performance Characteristics: The C&K CD10CM0SB provides extended mechanical and electrical life ratings (20,000 steps versus 10,000 steps), representing improved durability for high-cycle applications. Operating temperature range differs slightly (-25°C to 85°C versus -30°C to 85°C); applications requiring operation below -25°C require evaluation against specific environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the C&K CD10CM0SB be used as a direct replacement for the TE Connectivity 1825007-3 in existing designs?

A: Yes, the C&K CD10CM0SB is electrically and mechanically compatible for direct substitution. All critical parameters including circuit type, switching capacity, voltage/current ratings, actuator configuration, and termination style are identical. PCB footprint verification is required due to dimensional differences in height and length.

Q: What are the key differences between these two components?

A: The primary differences are: (1) Product status—the TE Connectivity part is obsolete while the C&K part is active; (2) Physical dimensions—the C&K part is more compact; (3) Mechanical and electrical life—the C&K part offers double the cycle rating; (4) Operating temperature minimum—the C&K part operates to -25°C versus -30°C; (5) Regulatory compliance—the C&K part carries current ROHS3 and REACH certifications.

Q: Are there any PCB layout considerations when switching from the TE Connectivity 1825007-3 to the C&K CD10CM0SB?

A: Yes. The C&K CD10CM0SB has a lower profile (0.168" versus 0.291" height) and shorter length (0.315" versus 0.394"). While the pitch and termination style remain identical, the reduced footprint may allow for tighter component spacing. Verify that the lower profile does not create clearance issues with adjacent components or enclosure constraints.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 1825007-3 packaging is listed as standard, while the C&K CD10CM0SB is supplied in tube packaging. Tube packaging is standard for surface mount components and does not affect component functionality or compatibility.

Q: Are both parts suitable for washable PCB assembly processes?

A: Yes, both components are rated as washable, confirming compatibility with aqueous and semi-aqueous cleaning processes commonly used in modern PCB manufacturing.

Q: What is the significance of the different mechanical and electrical life ratings?

A: The C&K CD10CM0SB provides 20,000 steps of mechanical and electrical life compared to 10,000 steps for the TE Connectivity part. This represents enhanced durability and extended component lifespan, particularly beneficial for applications with frequent switch actuation cycles.

Q: Do these components have identical moisture sensitivity levels?

A: Yes, both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are export control classifications identical for both parts?

A: Yes, both components share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, confirming equivalent export control and tariff treatment.
