Substitute Part Grouping Explanation

Substitute parts for the 7109MD9AV2LE are identified based on electrical and mechanical parameter equivalence within the C&K 7000 series toggle switch family. The substitution criteria are strictly limited to the following parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator specifications (Standard Round, 6.86mm length, Brass Chrome Plated)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Features (Epoxy Sealed Terminals)

Parts meeting all these criteria are classified as direct substitutes. Variations in product status and compliance certifications do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 7109MD9AV2RE serves as a direct functional equivalent to the 7109MD9AV2LE. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and equivalent performance in circuit applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 7109MD9AV2LE is obsolete, while the 7109MD9AV2RE maintains active production status. The 7109MD9AV2RE is RoHS Compliant and REACH Affected, whereas the 7109MD9AV2LE is RoHS non-compliant and REACH Unaffected. Selection between these parts should be based on regulatory requirements applicable to the end application and system design timeline.

Frequently Asked Questions (FAQ)
