EG1390B Equivalent & Substitute Parts

Part Overview

The EG1390B is a slide switch manufactured by E-Switch, featuring DPDT (Double Pole Double Throw) configuration with 300mA DC current rating at 4V. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part is surface-mounted with gull wing termination, designed for low-voltage switching applications requiring reliable on-on functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EG1390B is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain identical switching topology
• Switch Function: Must be On-On for equivalent operational behavior
• Current Rating: Must support minimum 300mA DC
• Voltage Rating: Must support minimum 4V DC operation
• Mounting Type: Must be Surface Mount for PCB compatibility
• Termination Style: Must be Gull Wing for footprint compatibility
• Actuator Length: Must be 2.00mm for mechanical fit
• RoHS Compliance: Must meet ROHS3 requirements for regulatory alignment

The JS202011SCQN from C&K meets all substitution criteria. While it features a higher voltage rating (6V) and extended temperature range (-40°C to 85°C), these represent performance enhancements rather than incompatibilities. The substitute maintains identical current rating, circuit configuration, mounting method, and termination style.

Parameter Comparison

Engineering Selection Recommendations

The JS202011SCQN is the designated substitute for the obsolete EG1390B. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring regulatory alignment for current manufacturing standards.

The substitute provides enhanced performance characteristics: higher voltage rating (6V versus 4V) and extended operating temperature range (-40°C to 85°C versus -10°C to 60°C). These improvements ensure compatibility with a broader range of application environments without compromising the original design intent.

The JS202011SCQN is actively manufactured and maintained in production inventory, providing supply chain continuity for applications previously dependent on the EG1390B.

Frequently Asked Questions (FAQ)

Q: Can the JS202011SCQN directly replace the EG1390B in existing designs?

A: Yes. Both components share identical circuit configuration (DPDT), current rating (300mA DC), mounting type (Surface Mount), termination style (Gull Wing), and actuator length (2.00mm). The substitute's higher voltage rating and extended temperature range do not create incompatibility with designs specified for 4V operation.

Q: What is the difference in switch travel between these parts?

A: The EG1390B has 1.50mm switch travel, while the JS202011SCQN has 2.00mm. This difference affects actuator engagement characteristics but does not prevent functional substitution in standard on-on switching applications.

Q: Are there packaging differences between the main part and substitute?

A: The EG1390B is supplied as standard packaging. The JS202011SCQN is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual assembly and automated pick-and-place operations.

Q: Does the substitute meet the same compliance requirements?

A: Yes. Both the EG1390B and JS202011SCQN are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8536.50.9050.

Q: What is the electrical life difference, and does it affect substitution?

A: The EG1390B specifies 10,000 electrical cycles, while the JS202011SCQN specifies 5,000 cycles. Applications requiring cycle counts exceeding 5,000 should evaluate this parameter against actual operational requirements.
