ADP02S Equivalent & Substitute Parts

Part Overview

The ADP02S is a surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. It is a single-pole, single-throw (SPST) switch with 2 positions, rated for 25mA at 24VDC, featuring a piano actuator and gold-plated copper alloy contacts. The ADP02S is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADP02S is determined by strict compatibility across the following parameters:

Critical Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (2)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Surface Mount, Right Angle)
• Termination style (Gull Wing)
• Pitch (0.100" / 2.54mm)

Allowable Variation Parameters:

• Current rating: The substitute part may exceed the original rating (25mA minimum required)
• Operating temperature range: The substitute may provide an extended range
• Electrical life cycles: The substitute may exceed the original specification
• Product status: Active substitutes are preferred for obsolete parts
• Compliance certifications: RoHS and REACH status may differ

The CTS Electrocomponents 193-2MS meets all critical matching parameters and provides enhanced electrical performance characteristics, making it a direct functional substitute for the ADP02S.

Parameter Comparison

Engineering Selection Recommendations

The CTS Electrocomponents 193-2MS is a direct functional substitute for the obsolete TE Connectivity ADP02S. Both components share identical circuit topology, voltage rating, actuator configuration, and PCB footprint characteristics.

Substitution Basis:

The 193-2MS provides enhanced electrical performance with a current rating of 50mA compared to the ADP02S 25mA rating, ensuring compatibility with applications designed for the original part. The substitute maintains the same 24VDC voltage specification and piano actuator interface.

Compliance Advantage:

The 193-2MS holds active product status with RoHS3 compliance, whereas the ADP02S is obsolete and RoHS non-compliant. For new designs or production continuity, the 193-2MS is the appropriate selection.

Mechanical Compatibility:

The 193-2MS exhibits a slightly increased height above board (0.359" versus 0.303") and extended electrical life rating (7,000 cycles versus 1,000 cycles). These characteristics do not preclude substitution in standard applications but require verification of available PCB clearance in space-constrained designs.

Temperature Performance:

The 193-2MS provides an extended lower operating temperature limit of -40°C compared to the ADP02S -30°C specification, offering improved performance in cold environment applications.

Frequently Asked Questions (FAQ)

Q: Can the 193-2MS be used as a direct replacement for the ADP02S in existing designs?

A: Yes. The 193-2MS maintains identical circuit configuration (SPST), voltage rating (24VDC), actuator type (piano), mounting style (surface mount, right angle), termination (gull wing), and pitch (0.100"). The increased current rating (50mA) and electrical life (7,000 cycles) provide enhanced performance margins.

Q: What is the primary difference between these two parts?

A: The ADP02S is an obsolete component with a 25mA current rating and 1,000 cycle electrical life. The 193-2MS is an active product with a 50mA current rating, 7,000 cycle electrical life, and RoHS3 compliance. Both share the same functional interface and PCB footprint.

Q: Are there mechanical compatibility concerns with the 193-2MS?

A: The 193-2MS has a height above board of 0.359" compared to the ADP02S 0.303". Designs with minimal vertical clearance above the switch location require verification that the additional 0.056" height does not create interference with overlying components or enclosure features.

Q: Does the 193-2MS meet current regulatory requirements?

A: Yes. The 193-2MS is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The ADP02S is RoHS non-compliant and obsolete.

Q: What is the packaging format for the 193-2MS?

A: The 193-2MS is supplied in tube packaging, whereas the ADP02S packaging format is not specified in available documentation.

Q: Can the 193-2MS handle higher current applications than the ADP02S?

A: The 193-2MS is rated for 50mA at 24VDC, compared to the ADP02S 25mA rating. Applications requiring current levels between 25mA and 50mA at 24VDC are within the 193-2MS specification. Applications exceeding 50mA require alternative component selection.
