ADTSM25SV Equivalent & Substitute Parts

Part Overview

The ADTSM25SV is an active-status tactile switch manufactured by APEM Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) surface mount component. This switch is designed for applications requiring momentary contact actuation with a contact rating of 0.05A at 12VDC. The part is ROHS3 compliant and carries unlimited moisture sensitivity classification (MSL 1), making it suitable for standard industrial and consumer electronics applications. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADTSM25SV is determined by the following critical parameters:

• Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), and switch function (Off-Mom) must be identical
• Mechanical Compatibility: Surface mount mounting type, gull wing termination, 12.00mm x 12.00mm outline dimensions, and 0.35mm switch travel must match
• Environmental Compliance: Operating temperature range (-25°C ~ 70°C), RoHS3 compliance, and MSL 1 classification must be maintained
• Regulatory Status: Product must be active status with REACH unaffected and EAR99 ECCN classification

The substitute part TL3300AF160QSSDOME from E-Switch meets all critical electrical and mechanical parameters while maintaining full regulatory compliance. Variations in actuator height (7.30mm vs. 8.50mm), operating force (160gf vs. 320gf), and actuator type do not prevent substitution when PCB layout and application force requirements accommodate these differences.

Parameter Comparison

Engineering Selection Recommendations

Both the ADTSM25SV and TL3300AF160QSSDOME are active-status components with full ROHS3 compliance and REACH unaffected classification, meeting current regulatory requirements for industrial and consumer applications. The TL3300AF160QSSDOME offers higher inventory availability (2341 pcs vs. 973 pcs) and includes documented mechanical life specification (1,000,000 cycles), providing additional lifecycle data for design validation. Selection between these parts should be based on supply chain requirements, packaging preference (Tray vs. Tape & Reel), and application-specific force requirements, as the TL3300AF160QSSDOME operates at 160gf compared to the ADTSM25SV at 320gf.

Frequently Asked Questions (FAQ)

Q: Can the TL3300AF160QSSDOME directly replace the ADTSM25SV on existing PCBs?

A: Yes, provided the PCB layout accommodates the 7.30mm actuator height of the TL3300AF160QSSDOME versus the 8.50mm height of the ADTSM25SV. The identical 12.00mm x 12.00mm outline and gull wing termination ensure mechanical compatibility. Verify that the application does not require the higher 320gf operating force of the original part.

Q: What is the significance of the operating force difference (160gf vs. 320gf)?

A: Operating force determines the tactile feedback and actuation pressure required from the user. The ADTSM25SV requires 320gf (approximately 3.2N), while the TL3300AF160QSSDOME requires 160gf (approximately 1.6N). Applications sensitive to actuation force must account for this difference during design validation.

Q: Are there packaging considerations when substituting these parts?

A: The ADTSM25SV is supplied in Tray packaging, while the TL3300AF160QSSDOME is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and typically offers cost advantages for high-volume production. Tray packaging may be preferred for manual assembly or lower-volume applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are active-status products suitable for current design implementations.

Q: What is the significance of the stainless steel contact dome in the TL3300AF160QSSDOME?

A: The stainless steel contact dome is a material specification for the switch contact mechanism. This feature is documented in the TL3300AF160QSSDOME specification but does not affect electrical compatibility or substitution eligibility. It may provide enhanced corrosion resistance in specific environmental applications.
