ADPA02S DIP Switch SPST Piano Actuator Equivalent & Substitute Parts

Part Overview

The ADPA02S is a surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This component is a single-pole single-throw (SPST) switch with 2 positions, piano actuator, and a rated capacity of 25mA at 24VDC. The part is classified as obsolete, making identification of active equivalent components necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical performance and mechanical compatibility within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADPA02S is based on electrical and mechanical parameter alignment within the ADPA series. The substitute part 4-1571999-2 maintains compatibility through the following critical parameters:

• Circuit Configuration: Both parts are SPST switches
• Number of Positions: Both provide 2-position switching
• Actuator Type: Both utilize piano actuators with raised actuator levels
• Mounting Type: Both are surface mount configurations
• Series Designation: Both belong to the ADPA series
• Washability: Both parts are washable
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)

The substitute part 4-1571999-2 is an active product, whereas the ADPA02S is obsolete. This substitution enables continued component availability for applications requiring SPST 2-position DIP switches with piano actuators in surface mount configurations.

Parameter Comparison

Engineering Selection Recommendations

The ADPA02S is classified as obsolete and is no longer in active production. The substitute part 4-1571999-2 is the recommended equivalent for new designs and replacement applications. This substitute maintains functional equivalence through identical circuit configuration, position count, actuator type, and mounting methodology.

The substitute part 4-1571999-2 provides improved regulatory compliance, achieving ROHS3 compliance status compared to the non-compliant status of the original ADPA02S. Both parts maintain REACH Unaffected status and EAR99 export classification.

Selection of the substitute part 4-1571999-2 is appropriate for applications requiring SPST 2-position DIP switches with piano actuators in surface mount configurations where active product availability and regulatory compliance are required.

Frequently Asked Questions (FAQ)

Q: Can the 4-1571999-2 directly replace the ADPA02S in existing designs?

A: The 4-1571999-2 maintains electrical and mechanical compatibility with the ADPA02S through identical circuit configuration (SPST), position count (2), actuator type (piano), and surface mount mounting methodology. Both parts are washable and share the same moisture sensitivity level. The substitute is suitable for direct replacement in applications where the original part specifications are met.

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

A: The ADPA02S is obsolete, while the 4-1571999-2 is an active product. Additionally, the 4-1571999-2 achieves ROHS3 compliance, whereas the ADPA02S is RoHS non-compliant. Both parts are functionally equivalent within the specified electrical and mechanical parameters.

Q: Are there packaging differences between the ADPA02S and 4-1571999-2?

A: The ADPA02S is supplied with dash packaging, while the 4-1571999-2 is supplied in tube packaging. This difference affects handling and storage but does not impact electrical or mechanical performance.

Q: What electrical parameters must be matched for substitution?

A: Critical electrical parameters for substitution include circuit configuration (SPST), number of positions (2), and contact material (copper alloy with gold finish). Both parts operate within the same voltage and current specifications for the ADPA series.

Q: Are both parts suitable for washable applications?

A: Yes, both the ADPA02S and 4-1571999-2 are rated as washable components, maintaining functionality after cleaning processes.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that both parts have no moisture sensitivity restrictions and do not require special moisture control handling during storage or assembly.
