TE Connectivity 2-435640-9 DIP Switch SPST Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-435640-9 is an SPST DIP switch with rocker actuator rated for 60mA at 5VDC. This component is classified as Active product status and is designed for through-hole mounting applications requiring low-voltage switching control. The 2-position configuration with raised rocker actuator provides manual circuit control in compact form factor. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges, or when design requirements necessitate alternative voltage ratings, actuator types, or position configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 2-435640-9 is based on the following critical parameters: circuit configuration (SPST), mounting type (through hole), pitch spacing (0.100 inches), and termination style (PC pin). All identified substitute parts maintain SPST circuit topology and through-hole mounting compatibility.

Substitutes are grouped into two categories based on allowed parameter variations:

Category 1: Same Voltage Rating (5VDC) with Position Variation The TE Connectivity 3-5435640-7 maintains the 5VDC voltage specification and rocker actuator type but differs in position count (6 positions versus 2 positions). This substitute is applicable when circuit design requires multiple independent switching channels within the same footprint class.

Category 2: Alternate Voltage Rating (24VDC) with Actuator Type Variation The CTS Electrocomponents 208-2 and E-Switch KAS1102E operate at 24VDC with slide actuators instead of rocker actuators. These substitutes are applicable when system voltage requirements differ from the original 5VDC specification. Current ratings vary: CTS 208-2 is rated 50mA, and E-Switch KAS1102E is rated 25mA, both lower than the original 60mA specification.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 3-5435640-7 (6-Position Variant) This substitute is directly compatible with the original 2-435640-9 when circuit design requires expansion to 6 independent switching positions while maintaining 5VDC operation. The 3-5435640-7 provides ROHS3 compliance and sealed construction with washable features, addressing environmental durability requirements not present in the original part. Operating temperature range remains -55°C to 105°C. Selection of this substitute is appropriate for designs requiring regulatory compliance upgrade or enhanced environmental protection.

CTS Electrocomponents 208-2 (24VDC Slide Actuator) This substitute operates at 24VDC with slide actuator configuration and 50mA current rating. The 208-2 is applicable in systems where 24VDC supply voltage is standard and rocker actuator operation is not required. Operating temperature range is reduced to -55°C to 85°C. ROHS3 compliance is provided. Selection of this substitute requires verification that 24VDC system voltage and 50mA current rating are compatible with circuit requirements.

E-Switch KAS1102E (24VDC Slide Actuator) This substitute operates at 24VDC with slide actuator configuration and 25mA current rating. The KAS1102E is applicable in systems where 24VDC supply voltage is standard and lower current switching is acceptable. Operating temperature range is -40°C to 85°C. ROHS3 compliance and gold contact finish are provided. Selection of this substitute requires verification that 24VDC system voltage and 25mA current rating are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-5435640-7 be used as a direct replacement for the 2-435640-9?

A: The 3-5435640-7 maintains electrical compatibility at 5VDC with identical current rating (60mA) and operating temperature range (-55°C to 105°C). However, the 3-5435640-7 provides 6 positions instead of 2 positions, resulting in a longer package length (0.680 inches versus 0.280 inches). Direct substitution is possible only if circuit board layout accommodates the increased length and if the additional switching positions do not conflict with circuit design.

Q: What are the key differences between rocker and slide actuators?

A: The original 2-435640-9 features a rocker actuator, while the CTS 208-2 and E-Switch KAS1102E feature slide actuators. Rocker actuators provide pivoting motion, while slide actuators provide linear motion. Actuator type selection depends on user interface requirements and available panel space. Height above board differs: rocker actuators on the original part measure 0.340 inches, while the E-Switch slide actuator measures 0.275 inches.

Q: Can I use the CTS 208-2 or E-Switch KAS1102E in a 5VDC circuit?

A: No. Both the CTS 208-2 and E-Switch KAS1102E are rated for 24VDC operation. Using these parts in a 5VDC circuit will result in improper switch operation. These substitutes are applicable only in systems with 24VDC supply voltage.

Q: What is the impact of current rating differences among substitute parts?

A: The original 2-435640-9 is rated for 60mA. The CTS 208-2 is rated for 50mA, and the E-Switch KAS1102E is rated for 25mA. Current rating represents the maximum continuous current the switch contacts can safely carry. Selection of a substitute with lower current rating requires verification that circuit load current does not exceed the substitute part's rating. Exceeding current rating will result in contact degradation and premature failure.

Q: Are all substitute parts RoHS compliant?

A: The original 2-435640-9 is RoHS non-compliant. All three substitute parts (TE Connectivity 3-5435640-7, CTS 208-2, and E-Switch KAS1102E) are ROHS3 compliant. Selection of a RoHS-compliant substitute is required for applications subject to RoHS regulatory requirements.

Q: What is the operating temperature range difference between substitute parts?

A: The original 2-435640-9 and TE Connectivity 3-5435640-7 both operate from -55°C to 105°C. The CTS 208-2 operates from -55°C to 85°C. The E-Switch KAS1102E operates from -40°C to 85°C. Selection of a substitute with a narrower temperature range requires verification that the application environment remains within the specified limits.

Q: Do all substitute parts use the same pitch spacing?

A: Yes. All parts, including the original 2-435640-9 and all three substitutes, use 0.100-inch (2.54mm) pitch spacing with through-hole PC pin termination. This ensures mechanical compatibility with standard DIP switch footprints on printed circuit boards.
