Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 435626-2 is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPST)
• Current rating (25mA minimum)
• Voltage rating (24VDC)
• Mounting type (Through Hole)
• Contact material and finish (Copper Alloy with Gold plating)
• Pitch specification (0.100" / 2.54mm)
• Termination style (PC Pin)

Substitute Categories:

Direct Equivalent (5-435626-2): This part maintains identical electrical specifications, circuit configuration, and mounting characteristics as the main part. It differs only in cosmetic designation and RoHS compliance status, making it a direct functional replacement within the same product series.

Manufacturer Recommended Alternative (1825006-9): This part is classified as the manufacturer-recommended substitute. While it maintains the same electrical ratings (25mA, 24VDC, SPST), it introduces design differences including actuator type (Slide instead of Rocker), position count (6 instead of 5), and product series (GDS instead of 7000). This part carries Active product status and full RoHS3 compliance, making it suitable for new designs and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Form Factor and Function):

Select part number 5-435626-2 when the application requires identical physical and electrical characteristics to the original 435626-2. This direct equivalent maintains the 5-position rocker actuator configuration and operates within the same electrical parameters. Both parts are classified as obsolete; however, 5-435626-2 carries ROHS3 compliance certification, providing regulatory advantage for systems requiring environmental compliance documentation.

For New Designs and Long-Term Availability:

Select part number 1825006-9 when designing new systems or when long-term component availability is a requirement. This part carries Active product status from TE Connectivity, ensuring continued manufacturing and supply chain support. The 1825006-9 is fully ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The part operates at identical electrical ratings (25mA, 24VDC, SPST) and maintains through-hole mounting with PC pin termination.

Design Considerations for 1825006-9 Substitution:

The 1825006-9 introduces the following differences that require circuit board layout evaluation:

• Actuator type changes from rocker to slide (standard), affecting user interface and PCB footprint
• Position count increases from 5 to 6, requiring verification that the application logic accommodates the additional position
• Operating temperature range narrows from -55°C to 105°C to -30°C to 85°C; verify application temperature requirements
• Mechanical and electrical life ratings decrease from 7,000 cycles to 1,000 cycles; assess application duty cycle requirements
• Height above board reduces from 0.290" (7.37mm) to 0.114" (2.90mm), providing improved board density
• Washable feature is enabled on 1825006-9, supporting advanced manufacturing processes

Frequently Asked Questions (FAQ)

Q: Can 5-435626-2 be used as a direct replacement for 435626-2 in existing assemblies?

A: Yes. The 5-435626-2 maintains identical electrical specifications (25mA, 24VDC, SPST), circuit configuration, number of positions (5), actuator type (rocker), and mounting characteristics (through-hole, PC pin termination). Physical dimensions and performance parameters are equivalent. The primary difference is RoHS3 compliance certification on the 5-435626-2.

Q: What are the key differences between 435626-2 and the recommended alternative 1825006-9?

A: The 1825006-9 differs in the following aspects: actuator type (slide instead of rocker), number of positions (6 instead of 5), product series (GDS instead of 7000), operating temperature range (-30°C to 85°C instead of -55°C to 105°C), mechanical life (1,000 cycles instead of 7,000 cycles), and electrical life (1,000 cycles instead of 7,000 cycles). Electrical ratings (25mA, 24VDC, SPST) and mounting type (through-hole) remain identical.

Q: Is the 1825006-9 suitable for applications requiring the full -55°C to 105°C temperature range?

A: No. The 1825006-9 operates within -30°C to 85°C. Applications requiring operation at temperatures below -30°C or above 85°C must retain the original 435626-2 or 5-435626-2 parts. Verify application temperature requirements before substitution.

Q: Does the change from rocker to slide actuator on the 1825006-9 affect PCB layout?

A: Yes. The actuator type change from rocker to slide requires PCB footprint verification. Additionally, the height above board decreases from 0.290" (7.37mm) to 0.114" (2.90mm), and the position count increases from 5 to 6. Physical layout and user interface considerations must be evaluated during design transition.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 5-435626-2 and 1825006-9 carry ROHS3 compliance certification. The original 435626-2 is marked as "Not applicable" for RoHS status. The substitute parts provide regulatory compliance advantage for systems requiring environmental certification.

Q: What is the mechanical life difference between the main part and the recommended alternative?

A: The 435626-2 and 5-435626-2 are rated for 7,000 mechanical cycles, while the 1825006-9 is rated for 1,000 mechanical cycles. Applications with high switching frequency must evaluate whether the reduced cycle rating of 1825006-9 meets operational requirements.

Q: Can the 1825006-9 be used in applications where the original part operates at 7,000 cycles?

A: The 1825006-9 is rated for 1,000 mechanical and electrical cycles. Applications requiring 7,000 cycles must retain the original 435626-2 or 5-435626-2. Duty cycle analysis is required to determine if the reduced rating is acceptable for the specific application.

Q: What is the product status difference, and why does it matter?

A: The 435626-2 and 5-435626-2 are classified as Obsolete, indicating discontinued manufacturing. The 1825006-9 is classified as Active, indicating current production and ongoing supply chain support. For new designs and long-term availability, the Active status of 1825006-9 provides supply chain security.

Q: Does the 1825006-9 washable feature affect compatibility?

A: The 1825006-9 includes a washable feature with tape seal, while the 435626-2 is not washable. This feature enables advanced manufacturing processes such as aqueous cleaning. For existing assemblies not requiring washable components, this difference is not a compatibility concern.
