Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1825008-2 is determined by equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: Hexadecimal (16-position capability)
• Number of positions: 16
• Actuator type: Rotary with shaft mechanism
• Mounting configuration: Through-hole technology
• Series family: DR series compatibility

Functional Compatibility Criteria: The substitute part must maintain identical position count and rotary selection logic to ensure direct replacement without circuit redesign. Through-hole mounting compatibility is required for PCB integration without mechanical modification. The raised actuator level specification ensures consistent operator interface and accessibility.

Compliance Considerations: While the main part carries obsolete status with RoHS non-compliance and REACH-affected designation, substitute parts may offer improved compliance posture. However, substitution decisions must account for existing system certifications and regulatory requirements applicable to the end application.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status Advantage: The substitute part 1825008-8 maintains active product status within the TE Connectivity ALCOSWITCH DR series, ensuring continued availability and manufacturing support. The obsolete classification of the main part 1-1825008-2 creates supply chain risk and limits access to replacement inventory beyond existing stock levels.

Compliance Improvement: The substitute part achieves ROHS3 compliance and REACH unaffected status, compared to the non-compliant and REACH-affected designation of the main part. This compliance posture aligns with current regulatory requirements in electronics manufacturing and may be mandatory for applications subject to RoHS Directive 2011/65/EU or REACH Regulation (EC) 1907/2006.

Electrical and Mechanical Specifications: The substitute part provides documented electrical ratings (0.4VA at 20VAC/DC), mechanical life (20,000 steps), and electrical life (20,000 steps) specifications. These parameters enable precise application matching and reliability assessment. The gold-plated copper alloy contacts support low-signal switching applications with enhanced contact reliability.

Mounting Configuration: The substitute part specifies right-angle through-hole mounting with PC pin termination at 0.100" (2.54mm) pitch. This configuration is standard for DIP switch applications and compatible with conventional PCB layouts. The documented height above board (0.413") and length (0.394") enable mechanical clearance verification.

Temperature Operating Range: The substitute part operates across -30°C to 85°C, providing thermal performance suitable for industrial and commercial applications. This range accommodates standard operating environments without thermal derating.

Frequently Asked Questions (FAQ)

Q: Can the 1825008-8 directly replace the 1-1825008-2 without PCB modification?

A: The substitute part maintains identical hexadecimal 16-position rotary selection logic and through-hole mounting technology. The right-angle mounting configuration and standard 0.100" pitch are compatible with conventional DIP switch PCB layouts. Physical dimensions and actuator interface remain consistent with the original design. No circuit redesign is required for functional substitution.

Q: What is the significance of the obsolete status for the main part?

A: Obsolete classification indicates that TE Connectivity has discontinued manufacturing and support for part 1-1825008-2. Existing inventory of 861 pieces represents finite supply. The substitute part 1825008-8 carries active status, ensuring long-term availability, manufacturing support, and access to replacement stock for system maintenance and field repairs.

Q: How do the electrical ratings of the substitute part affect application suitability?

A: The substitute part is rated for 0.4VA at 20VAC/DC maximum. Applications requiring switching of signals or loads exceeding these ratings require alternative component selection. The 20VAC/DC rating accommodates standard logic-level and low-power switching applications. Verification of actual circuit voltage and current requirements against these specifications is necessary during design review.

Q: What is the impact of RoHS and REACH compliance differences?

A: The main part carries RoHS non-compliance and REACH-affected designation, indicating presence of restricted substances or substances of very high concern. The substitute part achieves ROHS3 compliance and REACH unaffected status, eliminating regulatory restrictions in jurisdictions enforcing these directives. Applications subject to RoHS Directive 2011/65/EU or REACH Regulation (EC) 1907/2006 require the compliant substitute part.

Q: Are the mechanical and electrical life specifications of the substitute part adequate for the intended application?

A: The substitute part specifies 20,000 steps for both mechanical and electrical life. This rating defines the number of complete rotary cycles the switch can perform while maintaining specified electrical performance. Application duty cycle analysis is required to determine if this life rating meets system requirements. High-frequency switching applications or extended service life requirements may necessitate component life assessment.

Q: What packaging format is provided for the substitute part?

A: The substitute part 1825008-8 is supplied in tube packaging. This format is standard for DIP switch distribution and accommodates both manual and automated assembly processes. Tube packaging provides component protection during storage and handling while enabling efficient inventory management.

Q: How do the contact materials differ between the main and substitute parts?

A: The substitute part specifies copper alloy contacts with gold finish. Gold plating provides corrosion resistance and stable contact resistance over extended service life, particularly beneficial for low-signal switching applications. The main part contact material is not documented, limiting direct comparison. The gold-plated copper alloy contacts of the substitute part represent industry-standard contact technology for DIP switches.
