ADE05 Equivalent & Substitute Parts

Part Overview

The ADE05 is a DIP slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole single-throw (SPST) switch with 5 positions. The switch is rated for 100mA at 24VDC and features through-hole mounting with a standard slide actuator. The ADE05 is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across circuit topology, electrical ratings, and mechanical mounting characteristics.

Substitute Part Grouping Explanation

Substitution of the ADE05 is determined by strict equivalence across the following critical parameters: circuit configuration (SPST), number of positions (5), current rating (100mA minimum), voltage rating (24VDC minimum), mounting type (through hole), pitch (0.100"), termination style (PC pin), and actuator type (slide standard).

The substitute parts are grouped into two categories:

Direct Equivalent: Part 1825057-4 (TE Connectivity ALCOSWITCH Switches) maintains identical electrical and mechanical specifications to the ADE05, with the primary distinction being active product status and RoHS3 compliance. This part is the preferred direct replacement.

Compatible Substitutes: Parts 209-5MST (CTS Electrocomponents), SD05H0B (C&K), and SD05H1B (C&K) satisfy the core functional requirements of SPST 5-position 100mA slide switch configuration with through-hole mounting. These parts introduce variations in voltage rating, actuator height, contact material, body material, and mechanical life specifications, which must be evaluated against specific application requirements.

Engineering Selection Recommendations

Primary Recommendation: 1825057-4

The 1825057-4 is the direct equivalent replacement for the obsolete ADE05. This part maintains identical electrical specifications (100mA at 24VDC), mechanical configuration (5-position SPST through-hole with 0.100" pitch), and operating temperature range (-30°C to 85°C). The 1825057-4 carries active product status and RoHS3 compliance, eliminating regulatory and supply chain risks associated with the obsolete ADE05. Height above board differs by 0.004" (0.10mm), which is negligible for standard PCB applications. This part is suitable for direct substitution in new designs and production continuations.

Secondary Recommendations: SD05H1B and SD05H0B

The C&K SD05H1B and SD05H0B parts satisfy functional requirements for SPST 5-position 100mA slide switch applications. Both parts feature active product status and RoHS3 compliance. The SD05H1B maintains a raised actuator level consistent with the ADE05, while the SD05H0B features a flush, recessed actuator. Both parts offer extended mechanical and electrical life (2,000 cycles) compared to the ADE05 (1,000 cycles) and support expanded operating temperature range (-40°C to 85°C). Voltage rating is 25VDC, which exceeds the ADE05 requirement of 24VDC. Height above board is reduced to 0.178" (4.52mm), which may require PCB layout verification for clearance-sensitive applications. These parts are suitable for applications where C&K component qualification is acceptable and where extended lifecycle performance is beneficial.

Tertiary Recommendation: 209-5MST

The CTS Electrocomponents 209-5MST provides SPST 5-position 100mA slide switch functionality with active product status and RoHS3 compliance. This part features the lowest height above board (0.190" / 4.83mm) and extended electrical life (2,000 cycles). Voltage rating is 20VDC, which is below the ADE05 specification of 24VDC and requires application-level verification that circuit voltage does not exceed 20VDC. Contact material is beryllium copper rather than copper alloy. This part is suitable for applications with voltage constraints at or below 20VDC and where CTS component qualification is established.

Frequently Asked Questions (FAQ)

Q: Can the 1825057-4 be used as a direct drop-in replacement for the ADE05?

A: Yes. The 1825057-4 maintains identical electrical ratings (100mA at 24VDC), circuit configuration (SPST 5-position), mounting type (through-hole), pitch (0.100"), and termination style (PC pin). Height above board differs by 0.004" (0.10mm), which does not affect standard PCB applications. The 1825057-4 is the recommended direct replacement.

Q: What is the primary difference between the SD05H1B and SD05H0B?

A: The SD05H1B features a raised actuator level, while the SD05H0B features a flush, recessed actuator level. Both parts are otherwise identical in electrical specifications, mechanical life, and compliance status. Selection depends on actuator accessibility and PCB clearance requirements.

Q: Why does the 209-5MST have a lower voltage rating (20VDC) than the ADE05 (24VDC)?

A: The 209-5MST is manufactured by CTS Electrocomponents and is designed to different electrical specifications. This part is suitable only for applications where circuit voltage does not exceed 20VDC. Verification of application voltage requirements is necessary before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (1825057-4, 209-5MST, SD05H0B, and SD05H1B) carry RoHS3 compliance status. The ADE05 is RoHS non-compliant. Substitution to any of these parts satisfies RoHS regulatory requirements for new designs.

Q: What is the difference in mechanical life between the ADE05 and the C&K substitutes?

A: The ADE05 is rated for 1,000 mechanical cycles. The C&K parts (SD05H1B and SD05H0B) are rated for 2,000 mechanical cycles, providing extended lifecycle performance. The 209-5MST does not specify mechanical life.

Q: Do all substitute parts support the same operating temperature range as the ADE05?

A: The ADE05 operates from -30°C to 85°C. The substitute parts 209-5MST, SD05H0B, and SD05H1B operate from -40°C to 85°C, providing extended low-temperature performance. The 1825057-4 maintains the same -30°C to 85°C range as the ADE05.

Q: What packaging formats are available for the substitute parts?

A: All substitute parts are supplied in tube packaging. The ADE05 was supplied in bulk packaging. Tube packaging is standard for active DIP switch products and facilitates automated assembly processes.

Q: Can the substitute parts be used in applications requiring washable PCBs?

A: Yes. All substitute parts (1825057-4, 209-5MST, SD05H0B, and SD05H1B) are rated as washable, consistent with the ADE05 specification.

Q: What contact material is used in the substitute parts?

A: The 1825057-4 uses copper alloy contact material, matching the ADE05. The CTS 209-5MST and C&K SD05H1B and SD05H0B use beryllium copper contact material. Both materials are gold-finished and suitable for low-current switching applications.
