ADE12 DIP Switch SPST 12 Position Equivalent & Substitute Parts

Part Overview

The ADE12 is a 12-position DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole single-throw (SPST) switch with slide actuator operation. This component is rated for 100mA at 24VDC and is designed for through-hole mounting on printed circuit boards.

The ADE12 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADE12 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 12
• Current rating: 100mA minimum
• Voltage rating: 24VDC minimum
• Mounting type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Washable capability: Yes

Substitute Categories:

Direct Equivalent (1-1825057-0): TE Connectivity ALCOSWITCH Switches part manufactured within the same product family (ADE series). This part maintains identical electrical specifications and mechanical form factor. Product status is Active, providing current availability and supply chain support.

Similar Substitute (SD12H0B): C&K manufactured DIP switch meeting all critical electrical parameters with minor mechanical variations. Voltage rating of 25VDC exceeds the 24VDC requirement. Operating temperature range extends to -40°C. Mechanical and electrical life ratings are doubled (2,000 cycles versus 1,000 cycles). Actuator level differs (flush/recessed versus raised). Product status is Active.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 1-1825057-0 is the primary substitute for the obsolete ADE12. Both parts are manufactured by TE Connectivity within the ADE product family, ensuring design continuity and mechanical compatibility. The 1-1825057-0 carries Active product status with current manufacturing support. This part is ROHS3 compliant, meeting modern regulatory requirements. Electrical specifications are equivalent within the ADE series design parameters. Packaging is provided in Tape & Reel format, suitable for automated assembly processes.

For Alternative Substitution:

The SD12H0B from C&K provides a functional alternative when the direct equivalent is unavailable. This part meets all critical electrical parameters: 100mA current rating, 25VDC voltage rating (exceeding the 24VDC requirement), SPST configuration, and 12-position design. The SD12H0B is Active status with established supply availability. ROHS3 compliance and REACH compliance status are confirmed. Mechanical life and electrical life ratings are doubled (2,000 cycles), providing enhanced durability. Physical differences include flush/recessed actuator level (versus raised on ADE12) and reduced height above board (0.178" versus 0.232"). Packaging is provided in Tube format.

Compliance Considerations:

The ADE12 is RoHS non-compliant. Both substitute parts (1-1825057-0 and SD12H0B) are ROHS3 compliant. Design specifications must accommodate this regulatory transition if required by application standards or customer requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825057-0 be used as a direct drop-in replacement for the ADE12?

A: Yes. The 1-1825057-0 is manufactured by the same supplier (TE Connectivity ALCOSWITCH) within the same ADE product series. Both parts share identical circuit configuration (SPST), position count (12), mounting type (through hole), pitch (0.100"), and termination style (PC Pin). The 1-1825057-0 is Active status with current production support.

Q: What are the key differences between the ADE12 and SD12H0B?

A: Both parts are functionally equivalent for SPST 12-position DIP switch applications at 100mA. The SD12H0B has a higher voltage rating (25VDC versus 24VDC), extended operating temperature range (-40°C to 85°C versus -30°C to 85°C), and doubled mechanical/electrical life ratings (2,000 cycles versus 1,000 cycles). The SD12H0B has a flush/recessed actuator level and lower profile (0.178" versus 0.232" height). The SD12H0B is manufactured by C&K rather than TE Connectivity.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 1-1825057-0 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. The SD12H0B is supplied in Tube packaging. The original ADE12 is supplied in bulk. Packaging selection depends on assembly process requirements and production volume.

Q: Do the substitute parts meet RoHS requirements?

A: Yes. Both the 1-1825057-0 and SD12H0B are ROHS3 compliant. The original ADE12 is RoHS non-compliant. If RoHS compliance is required for the application, either substitute part satisfies this requirement.

Q: Can the SD12H0B be used in applications designed for the ADE12?

A: Yes, with mechanical verification. The SD12H0B meets all electrical requirements (100mA, 25VDC minimum, SPST, 12-position, through-hole, 0.100" pitch, PC pin termination). The primary consideration is the reduced height above board (0.178" versus 0.232") and flush/recessed actuator level. PCB layout and actuator access must be verified to confirm compatibility with the original design.

Q: What is the inventory status of these substitute parts?

A: The 1-1825057-0 has 1,025 pieces in stock (Active status). The SD12H0B has 952 pieces in stock (Active status). The original ADE12 has 1,126 pieces in stock but is Obsolete status with no future production planned.

Q: Are there any compliance or certification differences?

A: The ADE12 is RoHS non-compliant and REACH Unaffected. The 1-1825057-0 is ROHS3 compliant with Vendor Undefined REACH status. The SD12H0B is ROHS3 compliant and REACH Unaffected. All three parts carry EAR99 ECCN classification and identical HTSUS codes (8536.50.9065).
