Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7109SYV3LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Features (Epoxy Sealed Terminals)

The C&K 7109SYV3RE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7109SYV3RE is the direct equivalent for the obsolete 7109SYV3LE. Both components share identical electrical ratings, mechanical dimensions, and functional specifications. The 7109SYV3RE offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The 7109SYV3RE achieves RoHS compliance, whereas the 7109SYV3LE does not. For applications subject to RoHS directives or environmental regulations, the 7109SYV3RE is the appropriate selection. Both parts carry the same ECCN classification (EAR99) and HTSUS code (8536.50.9065), indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 7109SYV3RE directly replace the 7109SYV3LE in existing designs?

A: Yes. The 7109SYV3RE maintains identical electrical specifications (5A at 120V AC / 28V DC), mechanical dimensions (6.35mm circular cutout, 1/4-40 bushing thread), and functional characteristics (SPDT, On-Mom configuration). No design modifications are required for direct substitution.

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

A: The 7109SYV3LE is obsolete, while the 7109SYV3RE is an active product. Additionally, the 7109SYV3RE is RoHS compliant, whereas the 7109SYV3LE is not. All other specifications are equivalent.

Q: Are there any panel cutout or mounting considerations when switching from 7109SYV3LE to 7109SYV3RE?

A: No. Both parts require identical panel cutout dimensions (circular, 6.35mm diameter) and use the same bushing thread specification (1/4-40). Mechanical installation is identical.

Q: Does the 7109SYV3RE meet RoHS requirements?

A: Yes. The 7109SYV3RE is RoHS compliant. If your application requires RoHS compliance, this part satisfies that requirement, whereas the 7109SYV3LE does not.

Q: Are the electrical life ratings the same?

A: Yes. Both the 7109SYV3LE and 7109SYV3RE are rated for 40,000 electrical cycles, ensuring equivalent operational longevity.
