E301J1V4LE2 Equivalent & Substitute Parts

Part Overview

The E301J1V4LE2 is a rocker switch manufactured by C&K, featuring a 3PDT (three-pole, double-throw) circuit configuration rated for 5A at 125V AC/DC operation. This through-hole mounted switch is designed for On-On switching applications with a concave black actuator and sealed flux protection. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the E301J1V4LE2 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be 3PDT
• Switch Function: Must be On-On
• Current Rating: Must be 5A (AC/DC)
• Voltage Rating - AC: Must be 125V
• Voltage Rating - DC: Must be 28V
• Mounting Type: Must be Through Hole
• Actuator Type: Must be Concave (Standard V)
• Actuator Color: Must be Black
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must be -30°C to 85°C
• Electrical Life: Must be 30,000 Cycles
• Base Product Number: Must be E301J

The E301J1V4RE2 meets all substitution criteria as a direct equivalent from the same manufacturer and product series.

Parameter Comparison

Engineering Selection Recommendations

The E301J1V4RE2 is the direct functional equivalent for the obsolete E301J1V4LE2. Both parts share identical electrical specifications, mechanical configuration, and regulatory certifications. The primary distinction is product status: E301J1V4LE2 is obsolete while E301J1V4RE2 is active and currently available in inventory.

For new designs or component replenishment, E301J1V4RE2 is the appropriate selection. Both parts maintain cULus approval and ROHS3 compliance, ensuring regulatory continuity. The substitute part is available in bulk packaging with documented panel cutout dimensions (Rectangular - 17.96mm x 10.62mm), supporting standard PCB integration practices.

Frequently Asked Questions (FAQ)

Q: Can E301J1V4RE2 be used as a direct replacement for E301J1V4LE2?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, mounting type, actuator characteristics, and operating temperature range. The substitute is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. E301J1V4LE2 is obsolete; E301J1V4RE2 is active. Both parts meet identical electrical and mechanical specifications. E301J1V4RE2 includes documented panel cutout dimensions and is available in bulk packaging.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical regulatory approvals (cULus), RoHS3 compliance status, and export classifications (EAR99). Moisture sensitivity levels and HTSUS codes are identical.

Q: What are the critical parameters for substitution?

A: Substitution requires equivalence in circuit configuration (3PDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (125V AC / 28V DC), mounting type (Through Hole), actuator type and color (Concave Standard V / Black), termination style (PC Pin), and operating temperature range (-30°C to 85°C).

Q: Is packaging a consideration for substitution?

A: Packaging format does not affect electrical or mechanical compatibility. E301J1V4LE2 packaging is unspecified; E301J1V4RE2 is supplied in bulk. Both are suitable for through-hole PCB assembly.
