Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity ALCOSWITCH 435640-3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPST)
• Current rating (60mA)
• Voltage rating (5VDC)
• Actuator type (Rocker)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Pitch spacing (0.100" / 2.54mm)
• Operating temperature range (-55°C to 105°C)
• Contact material and finish (Copper Alloy, Gold)

Direct Equivalent: Part number 5435640-3 maintains identical electrical and mechanical specifications while offering improved compliance status (RoHS3 Compliant vs. non-compliant) and Last Time Buy availability.

Similar Configuration: Part number 3-5435668-0 shares the same series, circuit type, current and voltage ratings, but differs in position count (10 vs. 5), actuator level (Flush/Recessed vs. Raised), height above board, and overall length. This part is suitable only when the 10-position configuration and flush actuator profile are compatible with the application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Electrical Equivalent):

Part number 5435640-3 is the primary substitute for the obsolete 435640-3. Both components share identical electrical ratings (60mA, 5VDC, SPST), mechanical dimensions (0.340" height, 0.580" length), and functional characteristics. The 5435640-3 offers superior compliance status with RoHS3 certification and is available under Last Time Buy status, providing a defined procurement window for design transitions.

For Alternative Configuration (Different Position Count):

Part number 3-5435668-0 is suitable only when application requirements accommodate a 10-position switch configuration instead of 5-position. This part features a flush/recessed actuator profile (0.290" height vs. 0.340") and includes tape seal and washable features. The increased length (1.080" vs. 0.580") requires PCB layout verification. This part is currently in active production status with RoHS3 compliance.

Compliance Considerations:

The original 435640-3 is RoHS non-compliant. Both substitute options (5435640-3 and 3-5435668-0) are RoHS3 compliant, supporting regulatory requirements for new designs and manufacturing environments with RoHS mandates.

Frequently Asked Questions (FAQ)

Q: Can 5435640-3 be used as a direct replacement for 435640-3?

A: Yes. The 5435640-3 maintains identical electrical specifications (60mA, 5VDC, SPST), mechanical dimensions, and functional performance. Both components are from the TE Connectivity ALCOSWITCH 7100 series with matching pitch, termination style, and contact materials. The primary differences are packaging format (Tube vs. Bulk) and compliance status (RoHS3 Compliant vs. non-compliant).

Q: What are the key differences between 435640-3 and 3-5435668-0?

A: The primary differences are position count (5 vs. 10), actuator profile (Raised vs. Flush/Recessed), height above board (0.340" vs. 0.290"), and overall length (0.580" vs. 1.080"). The 3-5435668-0 also includes washable capability and tape seal features. Electrical ratings and operating temperature ranges are identical. Substitution requires verification that the 10-position configuration and different physical profile are compatible with the application.

Q: Are there any packaging differences between the substitute parts?

A: Yes. The original 435640-3 is supplied in bulk packaging. Both substitute parts (5435640-3 and 3-5435668-0) are supplied in tube packaging. Tube packaging provides improved component protection and organization for automated assembly processes.

Q: What is the significance of the Last Time Buy status for 5435640-3?

A: Last Time Buy status indicates a defined final procurement window before the part transitions to end-of-life status. Designers should plan component procurement accordingly to ensure supply continuity for production requirements.

Q: Can 3-5435668-0 be used in applications requiring a 5-position switch?

A: No. The 3-5435668-0 is a 10-position switch and is not functionally equivalent for applications requiring 5-position configuration. Position count is a critical parameter that determines switch functionality and cannot be substituted without application redesign.

Q: Are all three parts compatible with the same PCB footprint?

A: The 435640-3 and 5435640-3 share identical dimensions and are footprint-compatible. The 3-5435668-0 has different dimensions (increased length and reduced height) and requires PCB layout verification before substitution.

Q: What compliance certifications apply to these parts?

A: The 435640-3 is RoHS non-compliant. Both 5435640-3 and 3-5435668-0 are RoHS3 compliant. All three parts are classified under ECCN EAR99 and share the same HTSUS code (8536.50.9065).
