ADP05S Equivalent & Substitute Parts

Part Overview

The ADP05S is a DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 5-position SPST (Single Pole Single Throw) surface mount component with piano actuator. The device is rated for 25mA at 24VDC and features a raised piano actuator with gold-plated copper alloy contacts. The ADP05S is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADP05S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPST)
• Number of positions (5)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Surface Mount, Right Angle)
• Pitch (0.100" / 2.54mm)
• Termination style (Gull Wing)

Secondary Compatibility Criteria:

• Current rating (minimum 25mA required)
• Contact finish (Gold)
• Operating temperature range (must encompass or exceed -30°C ~ 85°C)
• Moisture sensitivity level (MSL 1)

The substitute parts listed below satisfy all primary compatibility criteria. Variations in secondary parameters are noted in the comparison table and must be evaluated against specific application requirements.

Engineering Selection Recommendations

1-1571999-2 (TE Connectivity ALCOSWITCH Switches)

The 1-1571999-2 is an active product from the same manufacturer and series as the ADP05S. This part maintains functional equivalence across all primary compatibility criteria. The 1-1571999-2 achieves ROHS3 compliance, addressing regulatory requirements that the obsolete ADP05S does not meet. This part is the preferred direct replacement for new designs requiring TE Connectivity ALCOSWITCH technology. Inventory availability is confirmed at 902 pieces.

193-5MS (CTS Electrocomponents)

The 193-5MS is an active product from an alternative manufacturer that satisfies all primary compatibility criteria. This part provides a higher current rating (50mA versus 25mA), supporting applications with increased current demands. The 193-5MS features an extended operating temperature range (-40°C ~ 85°C) and superior electrical life rating (7,000 cycles versus 1,000 cycles). ROHS3 compliance is achieved. The 193-5MS is suitable for applications where higher performance margins and extended operational life are required. Inventory availability is confirmed at 889 pieces. The 193-5MS is not washable, which may restrict use in applications requiring post-assembly cleaning processes.

Frequently Asked Questions (FAQ)

Q: Can the 1-1571999-2 be used as a direct replacement for the ADP05S?

A: The 1-1571999-2 satisfies all primary compatibility criteria for the ADP05S, including circuit configuration, position count, voltage rating, actuator type, mounting configuration, pitch, and termination style. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches within the same product series. The 1-1571999-2 is classified as active and achieves ROHS3 compliance. Direct substitution is supported for applications within the specified electrical and mechanical parameters.

Q: What are the key differences between the 1-1571999-2 and 193-5MS?

A: The 1-1571999-2 is manufactured by TE Connectivity ALCOSWITCH Switches, while the 193-5MS is manufactured by CTS Electrocomponents. The 193-5MS provides a higher current rating (50mA versus unspecified for 1-1571999-2), an extended operating temperature range (-40°C ~ 85°C versus unspecified for 1-1571999-2), and superior electrical life (7,000 cycles versus unspecified for 1-1571999-2). The 1-1571999-2 is washable; the 193-5MS is not. Both parts achieve ROHS3 compliance and MSL 1 moisture sensitivity rating.

Q: Is the 193-5MS suitable for applications requiring washability?

A: No. The 193-5MS is specified as not washable, while the ADP05S and 1-1571999-2 are both washable. Applications requiring post-assembly cleaning processes must use the 1-1571999-2 or confirm that the 193-5MS meets alternative cleaning requirements.

Q: What is the impact of the height difference between the ADP05S and 193-5MS?

A: The ADP05S has a height above board of 0.303" (7.70mm), while the 193-5MS measures 0.359" (9.12mm). This 0.056" (2.42mm) difference may affect PCB layout, component clearance, and enclosure fit. Applications with height constraints must verify that the 193-5MS accommodates the increased profile.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1-1571999-2 and 193-5MS are ROHS3 compliant. The original ADP05S is RoHS non-compliant. Designs requiring RoHS compliance must transition to either substitute part.

Q: What is the electrical life difference between the ADP05S and substitute parts?

A: The ADP05S is rated for 1,000 electrical cycles. The 193-5MS is rated for 7,000 electrical cycles, providing a 7-fold improvement in cycle life. The 1-1571999-2 electrical life rating is not specified. Applications requiring extended operational life should consider the 193-5MS.

Q: Can the 193-5MS handle higher current than the ADP05S?

A: Yes. The 193-5MS is rated for 50mA, compared to the ADP05S rating of 25mA. The 193-5MS supports applications requiring double the current capacity. The 1-1571999-2 current rating is not specified.

Q: What is the REACH compliance status of these parts?

A: The ADP05S is REACH Unaffected. The 193-5MS is REACH Unaffected. The 1-1571999-2 REACH status is listed as Vendor Undefined. Applications subject to REACH regulations should confirm compliance requirements with the manufacturer for the 1-1571999-2.
