ADF10S DIP Switch Equivalent & Substitute Parts

Part Overview

The ADF10S is a 10-position surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This component is a single-pole single-throw (SPST) slide-actuated switch rated for 25mA at 24VDC, designed for applications requiring multiple independent switching positions in a compact surface mount package. The ADF10S carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADF10S is determined by strict alignment with the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 10
• Mounting type: Surface Mount
• Actuator type: Slide (Standard)
• Actuator level: Flush, Recessed
• Pitch: 0.100" (2.54mm)
• Termination style: Gull Wing

Electrical Operating Range:

• Current rating must equal or exceed 25mA
• Voltage rating must equal or exceed 24VDC
• Operating temperature range must encompass -30°C to 85°C

Physical Compatibility:

• Height above board must not exceed 0.177" (4.50mm) to ensure PCB layout compatibility
• Length and overall footprint must accommodate existing board designs

The substitute parts identified below satisfy these core parameters while offering improvements in product status and regulatory compliance.

Engineering Selection Recommendations

4-1825059-9 (TE Connectivity ALCOSWITCH)

This substitute is manufactured by the same original equipment manufacturer as the ADF10S and maintains the same series designation (ADF). The part carries active product status and achieves RoHS3 compliance, addressing regulatory requirements for new designs and production. The 4-1825059-9 is available in Tape & Reel packaging, suitable for automated assembly processes. Specific electrical ratings are not provided in available documentation; verification against application requirements is necessary before selection.

219-10LPST (CTS Electrocomponents)

This substitute provides enhanced electrical performance with a 100mA current rating, exceeding the ADF10S specification of 25mA. The voltage rating of 20VDC is lower than the ADF10S 24VDC specification; this part is suitable only for applications operating at or below 20VDC. The 219-10LPST offers an extended operating temperature range (-55°C to 85°C) and doubled electrical life (2,000 cycles versus 1,000 cycles). RoHS3 compliance and active product status support long-term availability. Physical dimensions are compatible with ADF10S footprints, with a lower profile (0.160" versus 0.177" height). This part is packaged in Tube format.

Frequently Asked Questions (FAQ)

Q: Can the 4-1825059-9 directly replace the ADF10S in existing designs?

A: The 4-1825059-9 shares the same manufacturer, series, and core mechanical specifications as the ADF10S. Both are 10-position SPST surface mount DIP switches with flush recessed actuators, 0.100" pitch, and gull wing termination. The 4-1825059-9 is the recommended direct replacement for obsolete ADF10S inventory. Electrical ratings for the 4-1825059-9 are not fully specified; confirmation against application requirements is necessary.

Q: What are the voltage and current limitations when using the 219-10LPST as a substitute?

A: The 219-10LPST is rated for 100mA at 20VDC. Applications requiring 24VDC operation cannot use this part. Applications requiring current above 100mA cannot use this part. The 219-10LPST is suitable only for circuits operating at 20VDC or lower with current demands up to 100mA.

Q: Are there physical compatibility concerns with the 219-10LPST?

A: The 219-10LPST has a height above board of 0.160" compared to the ADF10S at 0.177". This lower profile is compatible with existing PCB layouts designed for the ADF10S. The pitch (0.100"), termination style (gull wing), and overall footprint are compatible. The 219-10LPST length is 1.058" versus the ADF10S at 1.078", a negligible difference for layout purposes.

Q: What is the difference in packaging between these parts?

A: The ADF10S is supplied in bulk packaging. The 4-1825059-9 is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The 219-10LPST is supplied in Tube packaging. Packaging selection depends on production volume and assembly process requirements.

Q: Do both substitutes meet RoHS compliance requirements?

A: Yes. Both the 4-1825059-9 and 219-10LPST carry RoHS3 compliance status. The original ADF10S is RoHS non-compliant. For new designs or production requiring RoHS compliance, either substitute is acceptable from a regulatory standpoint.

Q: What is the mechanical life difference between these parts?

A: The ADF10S specifies 1,000 mechanical cycles. The 219-10LPST specifies 2,000 electrical cycles. The 4-1825059-9 does not provide mechanical life specification in available documentation. For applications with high cycle count requirements, the 219-10LPST offers extended cycle life.

Q: Can these parts be used interchangeably in the same circuit?

A: Interchangeability depends on specific application requirements. All three parts share the same circuit configuration (SPST), position count (10), mounting type (surface mount), and actuator characteristics. Electrical requirements (voltage and current) must be verified against each part's ratings. The 219-10LPST voltage limitation (20VDC maximum) excludes it from 24VDC applications. The 4-1825059-9 is the preferred direct replacement when electrical ratings are not a constraint.
