Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3-435640-6 is determined by strict equivalence across the following critical parameters: circuit configuration (SPST), current rating (60mA), voltage rating (5VDC), actuator type (rocker), mounting method (through hole), contact material and finish (copper alloy with gold plating), operating temperature range (-55°C to 105°C), and mechanical/electrical life specifications (2,000 cycles). Position count, physical dimensions, and packaging format are secondary considerations that may vary depending on application requirements.

The substitute parts identified fall into two categories:

Direct Equivalent: Parts maintaining identical electrical and mechanical specifications with improved compliance status.

Functional Alternative: Parts sharing core electrical parameters but differing in position count, requiring application-level verification of compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-5435640-6

The 3-5435640-6 is the direct functional equivalent of the obsolete 3-435640-6. Both parts maintain identical electrical specifications (SPST, 60mA, 5VDC), mechanical configuration (5-position rocker, through-hole mounting), and physical dimensions. The 3-5435640-6 offers superior compliance status with ROHS3 certification and Last Time Buy availability, providing a clear migration path for designs currently using the obsolete part. This substitute requires no circuit or layout modifications.

Secondary Alternative: 5435640-5

The 5435640-5 shares all core electrical and mechanical parameters with the main part but provides 8 positions instead of 5. This part is currently in active production status with full ROHS3 compliance. Selection of this alternative is appropriate only when application requirements accommodate the increased position count and physical length (0.880" versus 0.580"). The 8-position configuration does not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 3-5435640-6 be used as a direct replacement for the 3-435640-6 without circuit modifications?

A: Yes. The 3-5435640-6 maintains identical electrical ratings (60mA, 5VDC, SPST), physical dimensions, mounting configuration, and contact specifications. No circuit or PCB layout changes are required.

Q: What is the primary difference between the 3-435640-6 and 3-5435640-6?

A: The primary differences are product status and regulatory compliance. The 3-435640-6 is obsolete and RoHS non-compliant, while the 3-5435640-6 is Last Time Buy status with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: When should the 5435640-5 be considered instead of the 3-5435640-6?

A: The 5435640-5 should be selected when the application requires 8 switch positions rather than 5. This part is in active production and fully compliant. The increased length (0.880" versus 0.580") must be verified against PCB layout constraints.

Q: Are there packaging differences between these substitutes?

A: The 3-435640-6 packaging format is not specified. The 3-5435640-6 and 5435640-5 are supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the washable feature, and does it apply to all substitutes?

A: The washable feature indicates the component can withstand aqueous cleaning processes. The 3-435640-6 and 3-5435640-6 are both washable. The 5435640-5 does not specify this feature.

Q: Are all three parts RoHS compliant?

A: No. The 3-435640-6 is RoHS non-compliant. Both the 3-5435640-6 and 5435640-5 are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: What is the mechanical life specification, and is it consistent across all parts?

A: All three parts specify 2,000 mechanical cycles and 2,000 electrical cycles, indicating identical durability and switching life under rated conditions.
