Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity ALCOSWITCH 435802-7 are identified based on electrical and mechanical compatibility within the following parameter constraints:

Direct Electrical Equivalents maintain identical circuit configuration (SPST), current rating (25mA), voltage rating (24VDC), and mechanical specifications including actuator type, mounting configuration, and pitch spacing.

Functional Alternatives share the same circuit type (SPST), mounting methodology (through-hole), pitch specification (0.100"), and operating temperature range, but differ in position count, current/voltage ratings, or actuator design to accommodate alternative application requirements.

The substitution logic prioritizes:

• Circuit configuration (SPST maintained across all alternatives)
• Mounting type and pitch compatibility (through-hole, 0.100" pitch)
• Operating temperature range (-55°C to 105°C)
• Contact material and finish specifications
• RoHS and regulatory compliance status

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Electrical and Mechanical Equivalence):

The TE Connectivity ALCOSWITCH 5435802-7 serves as the direct equivalent to the obsolete 435802-7. Both parts maintain identical electrical specifications (SPST, 25mA, 24VDC), mechanical configuration (9-position piano actuator, through-hole right-angle mounting, 0.100" pitch), and performance characteristics (7,000-cycle life). The 5435802-7 carries Last Time Buy status and achieves ROHS3 compliance, providing a compliant path forward for designs currently utilizing the 435802-7. Packaging differs (tube versus bulk), but electrical and mechanical compatibility is complete.

For Functional Alternatives (Application-Dependent Substitution):

The TE Connectivity ALCOSWITCH 2-5435668-7 represents a functional alternative within the 7100 series, suitable for applications where design parameters permit deviation from the original specification. This part maintains SPST circuit configuration, through-hole mounting, 0.100" pitch, and identical operating temperature range. However, the 2-5435668-7 differs in position count (7 versus 9), current rating (60mA versus 25mA), voltage rating (5VDC versus 24VDC), actuator type (rocker versus piano), and lifecycle specifications (2,000 cycles versus 7,000 cycles). This alternative is appropriate only when the application operates at 5VDC with reduced position requirements and can accommodate lower cycle life ratings. The 2-5435668-7 is currently active in production and ROHS3 compliant.

Compliance Considerations:

Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that the original 435802-7 does not meet. Selection between 5435802-7 and 2-5435668-7 should prioritize electrical specification alignment with the target application before considering compliance advantages.

Frequently Asked Questions (FAQ)

Q: Can the 5435802-7 directly replace the 435802-7 in existing designs?

A: Yes. The 5435802-7 maintains identical electrical ratings (SPST, 25mA, 24VDC), mechanical configuration (9-position piano actuator, through-hole right-angle mounting, 0.100" pitch), and performance characteristics (7,000-cycle life). The parts are electrically and mechanically equivalent. Packaging differs (tube versus bulk), but this does not affect functional compatibility.

Q: What are the key differences between the 5435802-7 and 2-5435668-7?

A: The 5435802-7 is a direct electrical equivalent to the 435802-7, maintaining 9 positions, 25mA current rating, and 24VDC voltage rating. The 2-5435668-7 is a functional alternative with reduced position count (7), higher current capacity (60mA), lower voltage rating (5VDC), different actuator type (rocker), and lower cycle life (2,000 cycles). Selection depends on application requirements.

Q: Can the 2-5435668-7 be used in a 24VDC application?

A: No. The 2-5435668-7 is rated for 5VDC operation. Using this part in a 24VDC application exceeds its voltage specification and will result in component failure. The 5435802-7 is the appropriate choice for 24VDC applications.

Q: What is the significance of the Last Time Buy status for the 5435802-7?

A: Last Time Buy status indicates that TE Connectivity will discontinue production of the 5435802-7 after a specified date. Procurement planning should account for this status when establishing long-term supply strategies. Current inventory availability is 3,048 pieces.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both the 5435802-7 and 2-5435668-7 achieve ROHS3 compliance. The original 435802-7 is non-compliant. Designs requiring regulatory compliance should transition to either substitute part.

Q: Does the rocker actuator on the 2-5435668-7 affect PCB layout compatibility?

A: The 2-5435668-7 features a flush, recessed rocker actuator, whereas the 435802-7 and 5435802-7 feature raised piano actuators. Both maintain identical height above board (0.290" / 7.37mm) and pitch spacing (0.100" / 2.54mm). However, actuator geometry differs, which may affect user interface ergonomics and panel cutout design. Mechanical drawings should be reviewed for specific application requirements.

Q: What is the mechanical life difference between the 5435802-7 and 2-5435668-7?

A: The 5435802-7 is rated for 7,000 mechanical and electrical cycles, matching the original 435802-7. The 2-5435668-7 is rated for 2,000 cycles. Applications requiring extended cycle life should utilize the 5435802-7.

Q: Can the 2-5435668-7 be used in applications requiring 9 switch positions?

A: No. The 2-5435668-7 provides 7 positions, whereas the 435802-7 and 5435802-7 provide 9 positions. Applications requiring 9 independent switch positions must use the 5435802-7.

Q: What is the current inventory status for substitute parts?

A: The 5435802-7 has 3,048 pieces in stock (tube packaging). The 2-5435668-7 has 1,011 pieces in stock (tube packaging). The original 435802-7 has 1,040 pieces in stock (bulk packaging).
