Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-435802-9 is determined by compatibility across the following critical parameters:

Circuit Configuration: Both the main part and substitute maintain SPST (Single Pole Single Throw) circuit topology, ensuring functional equivalence in switching applications.

Current and Voltage Ratings: The substitute part must support the electrical load requirements of 25mA at 24VDC or higher ratings to ensure safe operation within the original application envelope.

Mounting Architecture: Through-hole mounting compatibility is maintained across substitute candidates to ensure mechanical fit within existing PCB designs.

Operating Temperature Range: The substitute must support the full operational temperature spectrum of -55°C to 105°C to guarantee performance across all environmental conditions.

Actuator Accessibility: While the main part features a raised piano actuator, substitute parts with alternative actuator configurations (standard or flush) remain functionally compatible provided the switching mechanism operates within the specified electrical parameters.

Position Count Flexibility: The main part specifies 9 positions; substitute parts with equal or greater position counts (10 positions) accommodate the original application requirements while providing additional configuration capacity.

Compliance Status: Active product status and current compliance certifications (RoHS3, REACH Unaffected) are preferred to ensure long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The 1-1825006-7 is identified as the manufacturer-recommended substitute for the obsolete 1-435802-9. This substitution is supported by the following engineering considerations:

Product Status Alignment: The 1-1825006-7 maintains active product status within the TE Connectivity ALCOSWITCH portfolio, ensuring continued availability, technical support, and supply chain stability compared to the obsolete 1-435802-9.

Regulatory Compliance: The substitute part achieves RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in industrial and commercial applications. The main part's RoHS non-compliant and REACH Affected designations present compliance constraints for new designs and procurement.

Circuit Equivalence: Both parts maintain identical SPST circuit configuration, preserving functional switching behavior across the application.

Mechanical Compatibility: Through-hole mounting is retained in the substitute part, supporting integration into existing PCB layouts. The transition from raised piano actuator to flush, recessed standard actuator represents a design modification that requires mechanical validation within the specific application context.

Position Capacity: The substitute part provides 10 positions compared to the original 9 positions, offering expanded configuration capability without reducing functional capacity.

Washability Retention: Both parts maintain washable design characteristics, supporting manufacturing processes requiring post-assembly cleaning.

Selection of the 1-1825006-7 as a substitute is appropriate for applications requiring active product status, current regulatory compliance, and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825006-7 directly replace the 1-435802-9 in existing designs?

A: The 1-1825006-7 maintains SPST circuit configuration and through-hole mounting, supporting functional substitution. The transition from raised piano actuator to flush, recessed standard actuator requires mechanical validation to confirm compatibility with existing actuator access and user interface requirements.

Q: What is the significance of the position count difference (9 vs. 10)?

A: The main part provides 9 selectable positions, while the substitute offers 10 positions. This difference does not prevent substitution; the additional position capacity in the substitute part accommodates the original application requirements while providing expanded configuration options.

Q: Are the electrical ratings equivalent between the two parts?

A: The main part specifies 25mA at 24VDC. The substitute part electrical ratings are not provided in the available documentation. Electrical parameter verification through the manufacturer's detailed datasheet is necessary to confirm rating equivalence or superiority.

Q: What are the compliance implications of switching from the 1-435802-9 to the 1-1825006-7?

A: The 1-435802-9 is RoHS non-compliant and REACH Affected. The 1-1825006-7 is RoHS3 compliant and REACH Unaffected. This transition aligns new designs and procurement with current regulatory frameworks, eliminating compliance constraints associated with the obsolete part.

Q: How do the actuator differences affect application suitability?

A: The main part features a raised piano actuator; the substitute uses a flush, recessed standard actuator. Raised actuators provide extended reach for manual operation, while flush actuators minimize profile and reduce accidental actuation risk. Application requirements determine which actuator configuration is appropriate.

Q: Is the substitute part available in the same packaging format?

A: The main part packaging is not specified in the available data. The substitute part is available in bulk packaging. Packaging format confirmation through the manufacturer is recommended for procurement planning.

Q: What is the mechanical life expectancy of the substitute part?

A: The substitute part mechanical life rating is not provided in the available documentation. Mechanical life specifications should be obtained from the manufacturer's datasheet to confirm durability equivalence with the original part's 7,000-cycle rating.
