Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7301SY9V4LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 3PDT
• Current rating: 5A AC/DC
• Voltage ratings: 120V AC / 28V DC
• Switch function: On-On
• Mounting type: Through Hole
• Termination style: PC Pin
• Actuator specifications: Standard Round, 10.67mm length
• Operating temperature range: -30°C to 85°C
• Electrical life: 100,000 cycles
• Base product series: 7000 series

The C&K 7301SY9V4RE meets all electrical and mechanical parameters required for direct substitution. Both parts share identical circuit topology, current/voltage ratings, mounting configuration, and actuator geometry. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 7301SY9V4RE is the direct functional equivalent to the 7301SY9V4LE. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts is determined by regulatory and supply considerations:

The 7301SY9V4LE is obsolete and should not be selected for new designs or production. The 7301SY9V4RE is the active production part within the 7000 series platform and is recommended for all applications requiring 3PDT toggle switch functionality at 5A / 120V AC specifications.

The 7301SY9V4RE carries RoHS compliance certification, making it suitable for applications subject to RoHS directives. The part is REACH affected, indicating compliance with REACH chemical substance regulations. These certifications align with current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 7301SY9V4RE directly replace the 7301SY9V4LE in existing designs?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC / 28V DC, 3PDT), mechanical configuration (through-hole mounting, PC pin termination), and actuator specifications (standard round, 10.67mm). No circuit modifications or PCB redesign is required.
