C&K 7101J50AV2ME2 Rocker Switch SPDT 5A 120V - Equivalent & Substitute Parts

Part Overview

The C&K 7101J50AV2ME2 is a through-hole rocker switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part operates in On-On mode with a concave black actuator and epoxy-sealed PC pin terminals. The product is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC minimum)
• Voltage rating (120V AC / 28V DC minimum)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator type and color (Concave, Black)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)

Substitute parts are grouped into two categories:

Direct Substitute (Active Product): C&K 7101J50AV2SE2 maintains identical electrical and mechanical specifications with active product status and improved compliance documentation.

Similar Substitutes (Alternative Manufacturers): E-Switch parts 300AWSP1J5M7QE, 300SP1J5BLKM7QE, and 300SP1J5BLKM7RE meet core electrical and mechanical requirements but present variations in electrical life cycles and voltage ratings that require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C&K 7101J50AV2SE2

The C&K 7101J50AV2SE2 is the direct active-product equivalent. It maintains identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration, and operating temperature range. Both parts share the same base product number (7101J) and feature epoxy-sealed PC pin terminals. The 7101J50AV2SE2 carries active product status with RoHS compliance, making it the preferred choice for direct replacement in existing designs.

Secondary Options: E-Switch 300 Series

E-Switch alternatives provide functional equivalence with documented trade-offs:

• 300AWSP1J5M7QE: Maintains full electrical specifications (5A, 120V AC, 28V DC) with added IP67 ingress protection. Electrical life is reduced to 30,000 cycles compared to the original 100,000 cycles. Suitable for applications requiring environmental sealing where cycle life requirements are lower.

• 300SP1J5BLKM7QE: Meets electrical specifications (5A, 120V AC, 28V DC) with 40,000-cycle electrical life. Appropriate for moderate-duty applications where the reduced cycle count is acceptable.

• 300SP1J5BLKM7RE: Operates at reduced voltage and current ratings (0.4VA at 20V AC/DC). This part is suitable only for low-power signal switching applications and is not recommended for the original 5A/120V application.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 300AWSP1J5M7QE replace the C&K 7101J50AV2ME2 in all applications?

A: The 300AWSP1J5M7QE maintains electrical equivalence (5A, 120V AC, 28V DC) and mechanical compatibility. However, its electrical life rating of 30,000 cycles is lower than the original 100,000 cycles. Applications requiring high-cycle switching should use the C&K 7101J50AV2SE2 or 300SP1J5BLKM7QE instead.

Q: What is the difference between the E-Switch 300SP1J5BLKM7QE and 300SP1J5BLKM7RE?

A: Both parts share identical mechanical configuration and actuator specifications. The critical difference is voltage and current rating: 300SP1J5BLKM7QE is rated for 5A at 120V AC/28V DC, while 300SP1J5BLKM7RE is rated for 0.4VA at 20V AC/DC. The 300SP1J5BLKM7RE is not suitable for applications requiring 5A switching capacity.

Q: Is the C&K 7101J50AV2SE2 a direct pin-for-pin replacement?

A: Yes. The 7101J50AV2SE2 shares identical mounting type (through-hole, right-angle, vertical), termination style (PC pin), and panel cutout dimensions with the obsolete 7101J50AV2ME2. No PCB modifications are required.

Q: Why do the E-Switch parts have lower electrical life ratings?

A: Electrical life is determined by switch design and contact material specifications. The E-Switch 300 series uses different contact materials optimized for different performance characteristics, resulting in lower cycle ratings. Application requirements should determine whether this trade-off is acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. The C&K 7101J50AV2SE2 is RoHS compliant, and all E-Switch alternatives are RoHS3 compliant. All parts meet current environmental compliance requirements.

Q: Which substitute offers the best environmental protection?

A: The E-Switch 300AWSP1J5M7QE provides IP67 ingress protection (dust tight, waterproof), making it suitable for applications requiring environmental sealing. The other alternatives do not specify ingress protection ratings.
