ADP05 DIP Switch SPST Piano Actuator Equivalent & Substitute Parts

Part Overview

The ADP05 is a 5-position DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 25mA at 24VDC, featuring a piano actuator mechanism and through-hole right-angle mounting. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. The ADP05 maintains full functional compatibility with specified active alternatives while offering equivalent electrical and mechanical performance within defined parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADP05 is determined by strict equivalence across the following critical parameters: SPST circuit configuration, 5-position count, 25mA current rating, 24VDC voltage rating, piano actuator type, through-hole right-angle mounting, 0.100" pitch, and PC pin termination. All identified substitute parts maintain these core electrical and mechanical specifications. Substitutes are grouped into two categories: direct manufacturer equivalents from TE Connectivity ALCOSWITCH Switches (1-1571999-1) and cross-manufacturer alternatives from E-Switch (KAP1105E). Both substitute parts are classified as active products with current RoHS3 compliance, addressing the obsolescence status of the original ADP05 component.

Parameter Comparison

Engineering Selection Recommendations

1-1571999-1 (TE Connectivity ALCOSWITCH Switches)

The 1-1571999-1 represents the direct manufacturer equivalent within the TE Connectivity ALCOSWITCH Switches product line. This part maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements that the obsolete ADP05 does not satisfy. Selection of this substitute is appropriate for applications requiring continuity within the same manufacturer ecosystem and for designs subject to RoHS3 regulatory mandates.

KAP1105E (E-Switch)

The KAP1105E provides a cross-manufacturer substitute from E-Switch, maintaining full electrical and mechanical parameter equivalence to the ADP05. This part is classified as active with ROHS3 compliance and REACH unaffected status. The KAP1105E demonstrates extended mechanical and electrical life ratings (2,000 cycles versus 1,000 cycles) and an expanded operating temperature range (-40°C ~ 85°C versus -30°C ~ 85°C). Selection of this substitute is appropriate for applications requiring multi-source component availability and for designs benefiting from enhanced lifecycle performance specifications.

Both substitute parts satisfy the core functional requirements of the ADP05 and are suitable for direct replacement in new designs and production transitions from the obsolete component.

Frequently Asked Questions (FAQ)

Q: Can the 1-1571999-1 be used as a direct replacement for the ADP05 in existing designs?

A: Yes. The 1-1571999-1 maintains equivalent SPST circuit configuration, 5-position count, 25mA current rating, 24VDC voltage rating, piano actuator type, through-hole right-angle mounting, and 0.100" pitch specifications. The primary difference is product status transition from obsolete to active and RoHS3 compliance achievement.

Q: What are the physical differences between the ADP05 and KAP1105E?

A: The KAP1105E has a height above board of 0.402" (10.20mm) compared to the ADP05 at 0.294" (7.47mm). The KAP1105E length is 0.561" (14.25mm) versus the ADP05 at 0.578" (14.68mm). The KAP1105E uses Polybutylene Terephthalate (PBT) glass-filled body material and Phosphor Bronze contacts, while the ADP05 uses Polyphenylene Sulfide (PPS) body material and Copper Alloy contacts with gold finish. These dimensional and material differences require PCB layout verification prior to implementation.

Q: Are there washability differences between the substitute parts?

A: Yes. The ADP05 is specified as washable. The 1-1571999-1 washability is not specified in available documentation. The KAP1105E is specified as not washable. Applications requiring post-assembly washing processes must account for this parameter difference.

Q: What is the difference in mechanical and electrical life between the ADP05 and KAP1105E?

A: The ADP05 is rated for 1,000 mechanical and electrical cycles. The KAP1105E is rated for 2,000 mechanical and electrical cycles. This represents a 2x improvement in lifecycle performance for the E-Switch substitute.

Q: Which substitute part should be selected for RoHS3 compliant designs?

A: Both 1-1571999-1 and KAP1105E are ROHS3 compliant. The ADP05 is RoHS non-compliant. Selection between the two active substitutes depends on manufacturer preference, supply chain considerations, and physical dimension compatibility with existing PCB layouts.

Q: Is the operating temperature range difference between ADP05 and KAP1105E significant?

A: The ADP05 operates from -30°C to 85°C. The KAP1105E operates from -40°C to 85°C. The KAP1105E provides an additional 10°C of low-temperature capability. Applications operating below -30°C require the KAP1105E specification.

Q: What packaging format is supplied for each substitute part?

A: The 1-1571999-1 is supplied in tube packaging. The KAP1105E is supplied in tube packaging. Both formats are standard for DIP switch component distribution.
