Engineering Selection Recommendations

FSM2JART (TE Connectivity ALCOSWITCH): This direct substitute offers identical actuator height (4.30mm) and outline dimensions (6.00mm x 6.00mm) to the EVQ-22704M. The FSM2JART provides enhanced contact rating (0.05A @ 12VDC), extended mechanical life (100,000 cycles), and wider operating temperature range (-35°C ~ 105°C). ROHS3 compliance and active product status ensure long-term availability and supply chain stability.

TL59F260Q (E-Switch): This substitute maintains the 4.30mm actuator height matching the EVQ-22704M. Outline dimensions are marginally larger (6.20mm x 6.20mm). The TL59F260Q delivers improved contact rating (0.05A @ 12VDC) and doubled mechanical life (100,000 cycles). ROHS3 compliance and active status support ongoing design requirements. MSL rating of 1 (Unlimited) matches the original part.

TL59CF260Q (E-Switch): This option features an 8.00mm actuator height, representing a significant dimensional difference from the EVQ-22704M's 4.30mm height. Outline dimensions are 6.20mm x 6.20mm. The TL59CF260Q provides the same electrical enhancements as TL59F260Q (0.05A @ 12VDC, 100,000 cycles) with ROHS3 compliance and active product status. Selection of this variant requires PCB layout verification to accommodate the increased actuator height.

Frequently Asked Questions (FAQ)

Q: Can FSM2JART directly replace EVQ-22704M without PCB modifications?

A: Yes. FSM2JART maintains identical actuator height (4.30mm) and outline dimensions (6.00mm x 6.00mm) as EVQ-22704M, enabling direct footprint compatibility on existing PCB layouts.

Q: What is the primary difference between TL59F260Q and TL59CF260Q?

A: The actuator height differs: TL59F260Q is 4.30mm (matching EVQ-22704M), while TL59CF260Q is 8.00mm. Both share identical electrical specifications and outline dimensions (6.20mm x 6.20mm). Selection depends on available PCB clearance above the switch.

Q: Are all substitute parts RoHS compliant?

A: Yes. FSM2JART, TL59F260Q, and TL59CF260Q are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: How do contact ratings compare between the original and substitutes?

A: EVQ-22704M is rated 0.02A @ 15VDC. All three substitutes are rated 0.05A @ 12VDC, providing higher current capacity. Applications operating at the original 15VDC specification must confirm compatibility with the substitute's 12VDC rating.

Q: What is the mechanical life improvement in substitute parts?

A: EVQ-22704M specifies 50,000 cycles. FSM2JART, TL59F260Q, and TL59CF260Q all provide 100,000 cycles, doubling the mechanical life expectancy.

Q: Are there packaging differences between the main part and substitutes?

A: EVQ-22704M is supplied in Cut Tape (CT) packaging. FSM2JART, TL59F260Q, and TL59CF260Q are supplied in Tape & Box (TB) packaging, which may affect procurement and handling procedures.

Q: Which substitute offers the widest operating temperature range?

A: FSM2JART provides -35°C ~ 105°C, the widest range among all options. EVQ-22704M, TL59F260Q, and TL59CF260Q are limited to -20°C ~ 70°C.
