TE Connectivity ALCOSWITCH 435640-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 435640-6 is a DIP rocker switch with SPST (Single Pole Single Throw) configuration, rated for 60mA at 5VDC. This 9-position through-hole component features a raised rocker actuator with gold-plated copper alloy contacts and operates across an industrial temperature range of -55°C to 105°C. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity ALCOSWITCH 435640-6 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: SPST
• Current rating: 60mA
• Voltage rating: 5VDC

Mechanical Parameters (Non-Negotiable):

• Actuator type: Rocker
• Mounting type: Through Hole
• Termination style: PC Pin
• Pitch: 0.100" (2.54mm)
• Operating temperature range: -55°C to 105°C
• Contact material: Copper Alloy
• Contact finish: Gold

Position-Dependent Substitution: The number of positions (9 for the main part) is a critical parameter. Parts with identical position counts are direct substitutes. Parts with different position counts (such as 7-position variants) are functional alternatives only when circuit design accommodates the reduced position count.

Engineering Selection Recommendations

Direct Substitution: 5435640-6

The TE Connectivity ALCOSWITCH 5435640-6 is the primary equivalent for the obsolete 435640-6. This part maintains identical electrical specifications (SPST, 60mA, 5VDC), mechanical configuration (9 positions, rocker actuator, through-hole mounting), and physical dimensions (0.980" length, 0.340" height). The 5435640-6 carries Last Time Buy status and is ROHS3 compliant, providing regulatory alignment for new designs. Packaging is supplied in tube format. This substitution requires no circuit redesign or PCB layout modification.

Functional Alternative: 5435640-1

The TE Connectivity ALCOSWITCH 5435640-1 is a 7-position variant within the same 7100 series. All electrical parameters (SPST, 60mA, 5VDC) and mechanical characteristics (rocker actuator, through-hole mounting, PC pin termination) remain identical to the main part. The primary difference is the reduced position count (7 versus 9) and corresponding shorter length (0.780" versus 0.980"). This part is suitable only when circuit design accommodates the 7-position configuration. The 5435640-1 also carries Last Time Buy status and ROHS3 compliance.

Both substitute parts are manufactured by TE Connectivity ALCOSWITCH and share the same series designation (7100), ensuring design continuity within the product family.

Frequently Asked Questions (FAQ)

Q: Can the 5435640-6 be used as a direct replacement for the 435640-6?

A: Yes. The 5435640-6 is electrically and mechanically identical to the 435640-6. Both are 9-position SPST rocker switches rated for 60mA at 5VDC with identical through-hole mounting, pitch, and physical dimensions. No circuit or PCB modifications are required.

Q: What is the difference between the 5435640-6 and 5435640-1?

A: The primary difference is the number of positions: the 5435640-6 has 9 positions while the 5435640-1 has 7 positions. This results in a length difference of 0.200" (5.08mm). All other electrical and mechanical parameters are identical. The 5435640-1 is suitable only if the circuit design accommodates a 7-position switch.

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

A: The main part (435640-6) does not specify RoHS status. Both substitute parts (5435640-6 and 5435640-1) are ROHS3 compliant. For applications requiring RoHS compliance, the substitute parts are preferred.

Q: What is the packaging difference between the main part and substitutes?

A: The main part packaging is not specified. Both substitute parts are supplied in tube packaging, which is standard for DIP switch components.

Q: Can the 5435640-1 be used if only 7 positions are needed?

A: Yes, provided the circuit design is configured for 7 positions. The 5435640-1 maintains all electrical specifications (SPST, 60mA, 5VDC) and mechanical characteristics (rocker actuator, through-hole mounting) of the main part. The reduced length (0.780" versus 0.980") may provide PCB layout advantages in space-constrained applications.

Q: What is the product status of the substitute parts?

A: Both 5435640-6 and 5435640-1 carry Last Time Buy status, indicating limited future availability. Procurement planning should account for this status when selecting components for long-term production requirements.

Q: Are the operating temperature ranges identical across all three parts?

A: Yes. The main part (435640-6) and both substitutes (5435640-6 and 5435640-1) operate across the same temperature range of -55°C to 105°C.
