TE Connectivity ALCOSWITCH 435802-9 DIP Switch Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 435802-9 is an 8-position DIP switch with SPST circuit configuration, rated for 25mA at 24VDC. This through-hole, right-angle mounted component features a piano actuator and gold-plated copper alloy contacts suitable for industrial control and switching applications. The part is currently in active production status with 1089 pieces available in inventory.

Identification of equivalent and substitute parts becomes necessary when the primary part reaches end-of-life status, when supply constraints occur, or when design requirements mandate compliance with updated regulatory standards such as RoHS3.

Key Parameters

Substitute Part Grouping Explanation

Substitution of DIP switches is determined by electrical and mechanical parameter equivalence. The following parameters must remain identical for direct substitution:

• Circuit configuration (SPST)
• Number of positions (8)
• Current rating (25mA)
• Voltage rating (24VDC)
• Actuator type and level (Piano, Raised)
• Mounting type and orientation (Through Hole, Right Angle)
• Pitch spacing (0.100" / 2.54mm)
• Contact material and finish (Copper Alloy, Gold)
• Operating temperature range (-55°C to 105°C)
• Mechanical and electrical life ratings (7,000 Cycles)
• Height above board (0.290" / 7.37mm)
• Body material (Polyester PET, Glass Filled)
• Termination style (PC Pin)

The substitute part 5435802-9 meets all electrical and mechanical parameter requirements for direct substitution with the primary part 435802-9. Both components are manufactured by TE Connectivity ALCOSWITCH and belong to the 7000 series product line.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (435802-9): The 435802-9 is suitable for applications where RoHS non-compliance is acceptable and active production status is required. This part maintains full availability with 1089 pieces in current inventory. Selection of this part is appropriate for new designs with extended production timelines or applications operating in non-regulated markets.

Substitute Part Selection (5435802-9): The 5435802-9 provides complete electrical and mechanical equivalence to the primary part while offering ROHS3 compliance. This substitute is designated as Last Time Buy, indicating limited future availability. The 5435802-9 is the appropriate selection for applications requiring RoHS3 regulatory compliance, including European Union markets and industries subject to environmental regulations. With 3300 pieces in inventory, this part provides adequate supply for near-term requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Both parts share identical electrical performance, mechanical dimensions, and functional characteristics. Selection between them depends on regulatory compliance requirements and production timeline considerations rather than technical performance factors.

Frequently Asked Questions (FAQ)

Q: Can the 5435802-9 be used as a direct replacement for the 435802-9 in existing designs?

A: Yes. The 5435802-9 provides complete electrical and mechanical equivalence. All functional parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and dimensional specifications are identical. Direct substitution on printed circuit boards is possible without design modification.

Q: What is the primary difference between these two parts?

A: The primary differences are regulatory compliance status and product lifecycle stage. The 435802-9 is RoHS non-compliant and in active production. The 5435802-9 is ROHS3 compliant and designated as Last Time Buy. Electrical and mechanical performance are identical.

Q: Which part should be selected for new product designs?

A: For new designs intended for markets subject to RoHS3 regulations, the 5435802-9 is the appropriate selection. For applications in non-regulated markets or where RoHS compliance is not required, either part is functionally suitable. Consider long-term supply availability when making this decision.

Q: Are there packaging differences between these parts?

A: No. Both parts are supplied in tube packaging. Handling, storage, and installation procedures are identical.

Q: What does the Last Time Buy status mean for the 5435802-9?

A: Last Time Buy indicates that TE Connectivity will discontinue production of this part after a specified date. Existing inventory of 3300 pieces represents the final available supply. After depletion, this part number will no longer be available from the manufacturer.

Q: Are the mechanical life and electrical life ratings identical?

A: Yes. Both parts are rated for 7,000 mechanical cycles and 7,000 electrical cycles. Operating temperature range is identical at -55°C to 105°C for both components.

Q: What is the significance of the MSL rating difference?

A: The 435802-9 lists MSL as Not Applicable, while the 5435802-9 has MSL 1 (Unlimited). This indicates the 5435802-9 has no moisture sensitivity constraints during storage and handling. For standard industrial applications, this difference has no practical impact on component performance or reliability.
