EB2065-CE Equivalent & Substitute Parts

Part Overview

The EB2065-CE is an SPDT pushbutton switch manufactured by NKK Switches, rated for 3A at 125V AC. This panel-mount, rear-termination switch is designed for standard on-on switching applications with solder lug connections and epoxy sealed terminals. The part is currently active in production with 820 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configuration, and mechanical compatibility parameters are met, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2065-CE is determined by strict equivalence across the following parameters:

• Electrical Ratings: Current rating of 3A AC and voltage rating of 125V AC are mandatory for direct substitution
• Circuit Type: SPDT configuration is required; no alternative circuit types are acceptable
• Switch Function: On-on operation must be maintained
• Mounting Configuration: Panel mount, rear termination is required for mechanical compatibility
• Termination: Solder lug termination ensures PCB integration compatibility
• Compliance: RoHS3 compliance is required for regulatory alignment

The substitute part 1977739-1 meets all mandatory electrical and mechanical parameters, enabling direct substitution in applications requiring the EB2065-CE.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2065-CE and 1977739-1 are active production parts with ROHS3 compliance and identical electrical ratings. Selection between these parts should be based on:

• Supply Availability: EB2065-CE has 820 units in stock; 1977739-1 has 964 units in stock
• Operating Temperature Requirements: The 1977739-1 supports an extended temperature range (-20°C ~ 80°C) compared to the EB2065-CE (-10°C ~ 70°C), making it suitable for applications requiring broader thermal performance
• Mechanical Life Data: The EB2065-CE specifies 100,000 mechanical cycles; this parameter is not provided for 1977739-1
• Regulatory Compliance: Both parts meet ROHS3 and EAR99 export classification requirements

Frequently Asked Questions (FAQ)

Q: Can 1977739-1 be used as a direct replacement for EB2065-CE?

A: Yes. Both parts share identical electrical ratings (3A, 125V AC), SPDT circuit configuration, on-on switch function, panel mount rear termination, solder lug connections, and 25,000 cycle electrical life. All mandatory substitution parameters are equivalent.

Q: What are the differences between these parts?

A: The 1977739-1 offers an extended operating temperature range (-20°C ~ 80°C versus -10°C ~ 70°C). The EB2065-CE specifies 100,000 mechanical cycles; this specification is not provided for the 1977739-1. The EB2065-CE features a yellow actuator; the 1977739-1 actuator color is not specified.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, classified as EAR99, and share the same HTSUS code (8536.50.9033). Moisture sensitivity level is 1 (Unlimited) for both.

Q: Which part should be selected for high-temperature applications?

A: The 1977739-1 is suitable for applications requiring operation above 70°C, as it supports temperatures up to 80°C. The EB2065-CE is limited to 70°C maximum.

Q: Are the panel cutout dimensions compatible?

A: The EB2065-CE specifies a circular 6.35mm diameter panel cutout. Panel cutout dimensions for 1977739-1 are not provided in the available data.
