TE Connectivity 1-435802-8 DIP Switch Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-435802-8 is a 7-position DIP switch with SPST circuit configuration, piano actuator, and 24VDC rated operation. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. The original part features through-hole, right-angle mounting with gold-plated copper alloy contacts rated for 25mA at 24VDC operation across an operating temperature range of -55°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-435802-8 is determined by the following critical parameters: circuit configuration (SPST), number of positions (7), mounting type (through hole), pitch spacing (0.100"), and washable design capability. These parameters establish the functional and mechanical compatibility baseline.

The substitute parts identified fall into two categories based on parameter alignment:

MFR Recommended Substitute (5-5435166-2): Maintains identical circuit configuration (SPST), position count (7), mounting type (through hole), and pitch (0.100"). This part differs in actuator type (rocker versus piano) and product status (active versus obsolete). The rocker actuator represents a functional alternative within the same series platform.

Similar Manufacturer Substitute (BD07): Maintains identical circuit configuration (SPST), position count (7), mounting type (through hole), and pitch (0.100"). This part differs in manufacturer (C&K versus TE Connectivity), actuator type (slide versus piano), voltage rating (5VDC versus 24VDC), current rating (100mA versus 25mA), and operating temperature range (-40°C to 85°C versus -55°C to 105°C).

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement:

The TE Connectivity 5-5435166-2 is the manufacturer-recommended substitute, classified as active product status. This part maintains the same series platform (7000), circuit configuration (SPST), position count (7), and through-hole mounting architecture. The transition from piano to rocker actuator represents a design evolution within the same product family. This substitute is appropriate for applications where manufacturer continuity and active product support are required.

For Extended Operating Temperature Range:

The original 1-435802-8 operates across -55°C to 105°C. The C&K BD07 operates across -40°C to 85°C, representing a narrower temperature envelope. Selection of BD07 is restricted to applications operating within the -40°C to 85°C range.

For RoHS Compliance Requirement:

The original 1-435802-8 is RoHS non-compliant. The C&K BD07 is ROHS3 compliant. Selection of BD07 is appropriate for applications requiring RoHS compliance certification.

For Voltage and Current Rating Alignment:

The original 1-435802-8 is rated 25mA at 24VDC. The C&K BD07 is rated 100mA at 5VDC. These ratings are not interchangeable. Selection of BD07 requires circuit-level verification that the application operates at 5VDC with current requirements not exceeding 100mA.

Frequently Asked Questions (FAQ)

Q: Can the 5-5435166-2 directly replace the 1-435802-8 in existing designs?

A: The 5-5435166-2 maintains functional equivalence in circuit configuration (SPST), position count (7), mounting type (through hole), and pitch spacing (0.100"). The actuator type differs (rocker versus piano), which affects user interface and actuation force characteristics. Physical board layout compatibility requires verification of the right-angle mounting specification on the original part versus standard through-hole mounting on the substitute.

Q: What are the electrical compatibility constraints for the BD07 substitute?

A: The BD07 operates at 5VDC with 100mA current rating, compared to the original part's 24VDC at 25mA specification. These parameters are not compatible with circuits designed for 24VDC operation. The BD07 is suitable only for applications operating at 5VDC with current requirements within the 100mA limit.

Q: Does the BD07 meet temperature range requirements for the original application?

A: The BD07 operates across -40°C to 85°C, compared to the original part's -55°C to 105°C range. Applications requiring operation below -40°C or above 85°C cannot use the BD07 substitute.

Q: What is the significance of the pitch parameter in DIP switch substitution?

A: Pitch (0.100" or 2.54mm) defines the center-to-center spacing between switch positions. All identified substitutes maintain this pitch specification, ensuring compatibility with PCB footprints designed for the original 1-435802-8.

Q: How does the washable feature apply to substitute selection?

A: All identified substitutes (5-5435166-2 and BD07) retain the washable design feature, maintaining compatibility with manufacturing processes that include aqueous cleaning stages.

Q: What packaging considerations apply to these substitutes?

A: The 5-5435166-2 is supplied in tube packaging. The BD07 is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.

Q: Are there mechanical life differences between the original and substitute parts?

A: The original 1-435802-8 specifies 7,000 mechanical cycles. The BD07 specifies 10,000 mechanical cycles, representing improved durability. The 5-5435166-2 does not specify mechanical life in the provided data.
