ADE04S Equivalent & Substitute Parts

Part Overview

The ADE04S is a surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. It is a 4-position SPST slide switch rated for 100mA at 24VDC with a standard raised slide actuator and gold-plated copper alloy contacts. The ADE04S operates across a temperature range of -30°C to 85°C and features gull wing termination for surface mount applications.

The ADE04S is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where the original part is no longer manufactured or stocked.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADE04S is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPST)
• Number of positions (4)
• Current rating (100mA)
• Voltage rating (24VDC or higher)
• Actuator type (Slide, Standard)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Pitch (0.100" / 2.54mm)
• Contact finish (Gold)

Acceptable Variance Parameters:

• Height above board (within mechanical assembly constraints)
• Body material (functionally equivalent polymers)
• Operating temperature range (substitute must meet or exceed -30°C to 85°C)
• Mechanical and electrical life ratings (substitute must meet or exceed specified cycles)

Parts that deviate from primary criteria are classified as functional alternatives only and require design review before implementation.

Parameter Comparison

Engineering Selection Recommendations

1825058-7 (TE Connectivity ALCOSWITCH Switches)

The 1825058-7 is a direct equivalent to the ADE04S. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical specifications: 4-position SPST configuration, 100mA current rating, 24VDC voltage rating, and matching mechanical dimensions. The 1825058-7 is currently in active production status with 2,100 units in stock. The primary advantage is ROHS3 compliance, whereas the ADE04S is RoHS non-compliant. The 1825058-7 is the preferred direct replacement for new designs and production continuity.

219-4MST (CTS Electrocomponents)

The 219-4MST is a functional alternative with the following considerations:

The 219-4MST operates at 20VDC maximum, which is 4VDC lower than the ADE04S 24VDC rating. This part is suitable only for applications where the operating voltage does not exceed 20VDC. The 219-4MST features beryllium copper contacts instead of copper alloy, providing enhanced electrical performance with 2,000 electrical life cycles compared to 1,000 cycles for the ADE04S. The height above board is 0.170" (4.33mm), which is 0.049" lower than the ADE04S, requiring verification of PCB layout clearance. The 219-4MST is ROHS3 compliant and currently in active production with 2,324 units in stock. This part is suitable for applications operating at 20VDC or below where the reduced height profile is compatible with the mechanical design.

Frequently Asked Questions (FAQ)

Q: Can the 1825058-7 be used as a direct replacement for the ADE04S?

A: Yes. The 1825058-7 is a direct equivalent. Both parts share identical electrical ratings (100mA, 24VDC, SPST, 4-position), mechanical dimensions, and surface mount gull wing termination. The 1825058-7 is currently in active production and ROHS3 compliant, making it the preferred replacement for the obsolete ADE04S.

Q: What is the voltage limitation of the 219-4MST?

A: The 219-4MST is rated for 20VDC maximum, compared to the ADE04S 24VDC rating. The 219-4MST is suitable only for applications where the operating voltage does not exceed 20VDC. Exceeding this voltage rating voids the electrical specifications of the part.

Q: Does the 219-4MST fit in the same PCB footprint as the ADE04S?

A: The 219-4MST has a height above board of 0.170" (4.33mm), which is 0.049" lower than the ADE04S at 0.219" (5.55mm). The pitch and termination style are identical. PCB layout clearance must be verified before substitution, particularly for applications with height-constrained assemblies or overlying components.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1825058-7 and 219-4MST are ROHS3 compliant. The original ADE04S is RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is acceptable within their respective electrical ratings.

Q: What is the difference in contact material between the parts?

A: The ADE04S and 1825058-7 use copper alloy contacts. The 219-4MST uses beryllium copper contacts, which provide enhanced electrical performance and durability. The 219-4MST achieves 2,000 electrical life cycles compared to 1,000 cycles for the ADE04S and 1825058-7.

Q: Can the 219-4MST be used in a 24VDC application?

A: No. The 219-4MST is rated for 20VDC maximum. Operating this part at 24VDC exceeds its voltage specification and voids its electrical ratings. The 1825058-7 must be used for 24VDC applications.

Q: What is the operating temperature range for each part?

A: The ADE04S and 1825058-7 operate from -30°C to 85°C. The 219-4MST operates from -55°C to 85°C, providing a wider low-temperature operating range. For applications requiring operation below -30°C, the 219-4MST is suitable if the 20VDC voltage limitation is acceptable.

Q: Are all three parts washable?

A: Yes. The ADE04S, 1825058-7, and 219-4MST are all washable, supporting aqueous and semi-aqueous cleaning processes.
