TE Connectivity 4-435640-3 DIP Switch Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-435640-3 is a 12-position rocker actuator DIP switch with SPST circuit configuration, rated for 60mA at 5VDC. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement planning. The part features sealed construction, gold-plated copper alloy contacts, and through-hole PC pin termination suitable for applications requiring multi-position switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4-435640-3 is determined by the following critical parameters: circuit configuration (SPST), number of positions (12), current rating (60mA minimum), voltage rating (5VDC minimum), mounting type (through hole), pitch spacing (0.100"), and actuator type compatibility. Parts meeting these core electrical and mechanical specifications are classified as direct equivalents or functional substitutes.

The substitute parts identified fall into two categories:

Manufacturer Recommended Equivalent (MFR): The 4-5435640-1 maintains identical electrical ratings, circuit configuration, and mounting characteristics while differing in position count (10 vs. 12 positions) and product status (Last Time Buy vs. Obsolete).

Similar Manufacturer Alternative: The CTS Electrocomponents 206-12ST provides equivalent position count (12) and mounting configuration but operates at different voltage (24VDC vs. 5VDC) and current (50mA vs. 60mA) ratings with slide actuator type instead of rocker.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical and Mechanical Compatibility:

The 4-5435640-1 (TE Connectivity ALCOSWITCH) is the manufacturer-recommended equivalent. This part maintains identical voltage (5VDC) and current (60mA) ratings, rocker actuator configuration, and through-hole PC pin termination. The primary difference is a reduction from 12 to 10 positions. This part carries Last Time Buy status and is ROHS3 compliant, providing regulatory advantage over the obsolete 4-435640-3. Current inventory availability is significantly higher (6,467 units vs. 635 units).

For Applications Requiring 12-Position Configuration:

The CTS Electrocomponents 206-12ST maintains the 12-position count and through-hole mounting but introduces three critical differences: voltage rating of 24VDC (vs. 5VDC), current rating of 50mA (vs. 60mA), and slide actuator type (vs. rocker). This part is suitable only for applications where the circuit operates at 24VDC and the 50mA current rating is sufficient. The 206-12ST offers extended electrical life (10,000 cycles vs. 2,000 cycles) and active product status with ROHS3 compliance.

Selection between these substitutes depends on whether the application circuit can accommodate position count reduction (4-5435640-1) or voltage/current/actuator type changes (206-12ST).

Frequently Asked Questions (FAQ)

Q: Can the 4-5435640-1 directly replace the 4-435640-3 in all applications?

A: The 4-5435640-1 provides direct electrical and mechanical compatibility for applications requiring 10 or fewer switch positions. If the design requires all 12 positions to be functional, this substitute is not suitable. Both parts share identical voltage (5VDC), current (60mA), actuator type (rocker), and mounting specifications.

Q: What are the key differences between the rocker actuator (4-435640-3, 4-5435640-1) and slide actuator (206-12ST)?

A: Rocker and slide actuators differ in mechanical operation and user interface. Rocker actuators toggle between two positions with a rocking motion, while slide actuators move linearly. The 206-12ST slide actuator also operates at 24VDC rather than 5VDC, making it incompatible with circuits designed for the 5VDC rocker switches.

Q: Is the 206-12ST suitable as a substitute if my application operates at 5VDC?

A: No. The 206-12ST is rated for 24VDC operation. Using this part in a 5VDC circuit will result in improper switch function and potential component failure. Voltage rating is a critical parameter that cannot be overridden.

Q: What is the significance of the "Last Time Buy" status for the 4-5435640-1?

A: Last Time Buy status indicates that TE Connectivity will continue to supply this part for a limited period before discontinuation. Procurement planning should account for this status when selecting this as a long-term solution. The 206-12ST, with Active status, offers indefinite availability.

Q: How do the mechanical life ratings compare between these parts?

A: The 4-435640-3 and 4-5435640-1 both specify 2,000 mechanical cycles. The 206-12ST does not provide a mechanical life specification in the available data. The 206-12ST does specify 10,000 electrical cycles compared to 2,000 for the TE Connectivity parts.

Q: Are there packaging differences between these substitutes?

A: The 4-435640-3 packaging is not specified in the available data. The 4-5435640-1 is supplied in Tube packaging. The 206-12ST is also supplied in Tube packaging. Packaging format should be verified against procurement and assembly requirements.

Q: What compliance certifications apply to each part?

A: The 4-435640-3 (obsolete) has RoHS status listed as Not Applicable. Both the 4-5435640-1 and 206-12ST are ROHS3 compliant. For new designs or applications with regulatory requirements, the ROHS3-compliant parts are preferred.
