ADE02S Equivalent & Substitute Parts

Part Overview

The ADE02S is a surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This component is a single-pole, single-throw (SPST) switch with a 2-position slide actuator, rated for 100mA at 24VDC operation. The ADE02S is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADE02S is determined by strict electrical and mechanical compatibility across the following parameters:

Primary Electrical Criteria:

• Circuit configuration (SPST)
• Number of positions (2)
• Current rating (100mA minimum)
• Voltage rating (24VDC or higher)

Primary Mechanical Criteria:

• Actuator type (Slide, Standard)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Pitch (0.100" / 2.54mm)

Secondary Compatibility Factors:

• Operating temperature range compatibility
• Contact material and finish
• Washability
• Moisture sensitivity level

Two substitute parts meet the core electrical and mechanical requirements for the ADE02S: the TE Connectivity 1825058-1 and the CTS Electrocomponents 219-2MST. Both components maintain identical circuit configuration, position count, current rating, actuator type, mounting type, termination style, and pitch specifications.

Parameter Comparison

Engineering Selection Recommendations

1825058-1 (TE Connectivity ALCOSWITCH Switches)

The 1825058-1 is the primary substitute for the ADE02S. This component is manufactured by the same supplier and maintains identical electrical specifications (100mA, 24VDC) and mechanical form factor. The 1825058-1 is classified as Active product status, ensuring ongoing availability and supply chain continuity. The component achieves ROHS3 compliance, addressing regulatory requirements that the obsolete ADE02S does not meet. Physical dimensions are nearly identical, with mounting height differing by only 0.002" (0.05mm), ensuring compatibility with existing PCB layouts. Both components share identical operating temperature range, pitch, and termination specifications.

219-2MST (CTS Electrocomponents)

The 219-2MST is a secondary substitute option from an alternative manufacturer. This component maintains identical circuit configuration, position count, current rating, actuator type, mounting type, termination style, and pitch. The 219-2MST is classified as Active product status. The component achieves ROHS3 compliance. The voltage rating of 20VDC is lower than the ADE02S specification of 24VDC; this component is suitable only for applications operating at 20VDC or below. The 219-2MST provides an extended operating temperature range (-55°C ~ 85°C) and increased electrical life (2,000 cycles versus 1,000 cycles). Physical dimensions differ, with reduced mounting height (0.170" versus 0.219") and shorter overall length (0.258" versus 0.278"), requiring PCB layout verification. Contact material is Beryllium Copper rather than Copper Alloy.

Frequently Asked Questions (FAQ)

Q: Can the 1825058-1 be used as a direct replacement for the ADE02S?

A: Yes. The 1825058-1 maintains identical electrical ratings (100mA, 24VDC), circuit configuration (SPST), position count (2), actuator type (Slide Standard), mounting type (Surface Mount), termination style (Gull Wing), and pitch (0.100"). Physical dimensions are nearly identical. The component is manufactured by the same supplier and is classified as Active product status.

Q: What is the primary limitation of the 219-2MST as a substitute?

A: The 219-2MST has a voltage rating of 20VDC, which is lower than the ADE02S specification of 24VDC. This component is suitable only for applications operating at 20VDC or below. Additionally, physical dimensions differ, requiring PCB layout verification before implementation.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1825058-1 and 219-2MST are ROHS3 compliant. The original ADE02S is RoHS non-compliant, making either substitute preferable for applications subject to RoHS regulatory requirements.

Q: Do the substitute parts have the same moisture sensitivity level as the ADE02S?

A: Yes. All three components, including both substitutes, have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions.

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

A: The 1825058-1 is supplied in Bulk packaging. The 219-2MST is supplied in Tube packaging. The original ADE02S was supplied with standard packaging designation.

Q: Can the 219-2MST be used in applications requiring 24VDC operation?

A: No. The 219-2MST is rated for 20VDC maximum. Use of this component in 24VDC applications exceeds its voltage specification and is not permitted.

Q: How do the mechanical life specifications compare?

A: The ADE02S specifies 1,000 mechanical cycles. The 1825058-1 also specifies 1,000 mechanical cycles. The 219-2MST does not provide a mechanical life specification in the available data.

Q: Are there differences in contact material between the substitutes?

A: Yes. The ADE02S and 1825058-1 both use Copper Alloy contact material with gold finish. The 219-2MST uses Beryllium Copper contact material with gold finish. Both contact materials are suitable for the specified electrical ratings.

Q: What is the impact of the different mounting heights on PCB design?

A: The ADE02S has a mounting height of 0.219" (5.55mm). The 1825058-1 has a mounting height of 0.217" (5.50mm), a difference of 0.002" (0.05mm), which is negligible for most applications. The 219-2MST has a mounting height of 0.170" (4.33mm), a significant reduction requiring PCB layout verification to ensure clearance compatibility with surrounding components.
