Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7109MDAV2LE 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, Right Angle, Vertical)
• Actuator specifications (Standard Round, 6.86mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)
• Base product family (7109MD series)

The C&K 7109MDAV2RE meets all these criteria and qualifies as a direct substitute. The primary distinction between these components is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7109MDAV2RE is the direct substitute for the obsolete 7109MDAV2LE. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in panel-mount toggle switch applications requiring SPDT configuration at 5A/120V AC or 28V DC.

The 7109MDAV2RE offers the advantage of active product status, indicating ongoing manufacturer support and availability. Additionally, the substitute part achieves RoHS compliance, meeting current regulatory requirements for electronic component procurement in many jurisdictions. The REACH Affected status of the substitute reflects current regulatory classification and should be evaluated against specific procurement requirements.

Selection between these components should be based on regulatory compliance needs, supply chain availability, and system certification requirements. The electrical and mechanical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 7109MDAV2RE directly replace the 7109MDAV2LE in existing applications?

A: Yes. Both components are electrically and mechanically equivalent. The 7109MDAV2RE maintains identical current ratings (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting configuration (panel mount, right angle, vertical), actuator specifications, and termination style. Panel cutout dimensions and bushing thread specifications are identical, ensuring direct mechanical compatibility.

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

A: The 7109MDAV2LE is classified as obsolete, while the 7109MDAV2RE is an active product. The substitute part also achieves RoHS compliance, whereas the main part does not. These differences affect supply chain availability and regulatory compliance status rather than functional performance.

Q: Are there any compatibility concerns when substituting the 7109MDAV2RE for the 7109MDAV2LE?

A: No compatibility concerns exist from an electrical or mechanical standpoint. Both components feature identical SPDT circuit configuration, On-Mom switch function, and all specified parameters. Substitution is direct with no circuit modifications or mechanical adjustments required.

Q: What does the obsolete status of the 7109MDAV2LE mean for procurement?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this component. The 7109MDAV2RE, as an active product, represents the current equivalent offering from C&K and should be specified for new designs and ongoing procurement requirements.

Q: How do the RoHS compliance differences affect component selection?

A: RoHS compliance is a regulatory requirement in many markets and procurement specifications. The 7109MDAV2RE's RoHS compliance status makes it suitable for applications and regions with RoHS mandates, whereas the non-compliant 7109MDAV2LE may face restrictions in certain procurement contexts.
