ADF06ST Equivalent & Substitute Parts

Part Overview

The ADF06ST is a DIP slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 6-position SPST surface mount component with a 25mA current rating at 24VDC. This switch features a standard slide actuator with flush, recessed actuation level and gold-plated copper alloy contacts. The ADF06ST is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADF06ST are identified based on electrical and mechanical compatibility within the DIP switch category. The primary substitution criteria are:

Electrical Parameters: Circuit configuration (SPST), number of positions (6), current rating capability, and voltage rating must support the original application requirements.

Mechanical Parameters: Surface mount mounting type, gull wing termination style, 0.100" pitch spacing, and actuator type (slide standard) ensure physical and functional compatibility with existing PCB layouts.

Operational Parameters: Operating temperature range and washable feature compatibility determine suitability for equivalent environmental conditions.

Two substitute parts meet these criteria with varying degrees of parameter alignment:

2-1825059-9 provides direct electrical and mechanical equivalence to the ADF06ST with identical ratings and features, differing only in product status (active versus obsolete) and RoHS compliance level.

219-6LPST provides functional substitution with higher current and electrical life ratings, suitable for applications where the original 25mA specification can accommodate higher capacity, though with minor dimensional and material variations.

Parameter Comparison

Engineering Selection Recommendations

2-1825059-9 (Primary Substitute)

The 2-1825059-9 is the direct equivalent substitute for the ADF06ST. Both components share identical electrical specifications (25mA at 24VDC), mechanical configuration (6-position SPST, surface mount, gull wing termination), and operational parameters (1,000 cycle life, -30°C to 85°C operating range). The 2-1825059-9 is manufactured by the same supplier (TE Connectivity ALCOSWITCH Switches) within the same ADF series. The primary distinction is product status: the 2-1825059-9 is active with ROHS3 compliance, whereas the ADF06ST is obsolete and RoHS non-compliant. For applications requiring RoHS compliance or long-term component availability, the 2-1825059-9 is the appropriate selection.

219-6LPST (Secondary Substitute)

The 219-6LPST is a functional substitute suitable for applications where the original 25mA current specification can accommodate higher capacity. This CTS Electrocomponents part provides 100mA current rating and 2,000 cycle electrical life, exceeding the ADF06ST performance envelope. The 219-6LPST maintains mechanical compatibility (6-position SPST, surface mount, gull wing termination, 0.100" pitch) and operates across an extended temperature range (-55°C to 85°C). The voltage rating is 20VDC, which is lower than the ADF06ST 24VDC specification. The 219-6LPST is ROHS3 compliant and active. Selection of this part is appropriate when higher current capacity and extended electrical life are beneficial to the application and the 20VDC rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 2-1825059-9 be used as a direct replacement for the ADF06ST without circuit modification?

A: Yes. The 2-1825059-9 provides identical electrical and mechanical specifications to the ADF06ST. Both components are 6-position SPST switches rated at 25mA and 24VDC with surface mount gull wing termination and 0.100" pitch. No circuit modification is required for substitution.

Q: What is the primary difference between the ADF06ST and 2-1825059-9?

A: The ADF06ST is obsolete and RoHS non-compliant, while the 2-1825059-9 is an active product with ROHS3 compliance. Both components are electrically and mechanically identical.

Q: Can the 219-6LPST replace the ADF06ST in all applications?

A: The 219-6LPST provides functional substitution with higher current capacity (100mA versus 25mA) and extended electrical life (2,000 cycles versus 1,000 cycles). However, the voltage rating is 20VDC compared to the ADF06ST 24VDC specification. Substitution is appropriate only when the application voltage does not exceed 20VDC and the higher current capacity is acceptable or beneficial.

Q: Are there packaging differences between these substitute parts?

A: The ADF06ST packaging is listed as standard, while both 2-1825059-9 and 219-6LPST are supplied in tube packaging. Tube packaging is standard for DIP switch distribution and does not affect component functionality or PCB assembly compatibility.

Q: What is the mechanical life specification for these switches?

A: The ADF06ST specifies 1,000 mechanical cycles. The 2-1825059-9 also specifies 1,000 mechanical cycles. The 219-6LPST does not provide a mechanical life specification in the available data.

Q: Do all three parts meet washable switch requirements?

A: Yes. The ADF06ST, 2-1825059-9, and 219-6LPST are all rated as washable switches, suitable for applications requiring post-assembly cleaning processes.

Q: What is the height difference between the ADF06ST and 219-6LPST?

A: The ADF06ST has a height above board of 0.177" (4.50mm), while the 219-6LPST is 0.160" (4.06mm). This 0.017" (0.44mm) difference is minimal and does not typically affect PCB layout compatibility for standard surface mount applications.

Q: Are all three parts RoHS compliant?

A: The ADF06ST is RoHS non-compliant. Both the 2-1825059-9 and 219-6LPST are ROHS3 compliant. For applications subject to RoHS requirements, either substitute part is appropriate.
