EB2065-CH Equivalent & Substitute Parts

Part Overview

The EB2065-CH 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 1046 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configuration, and mechanical compatibility parameters align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

The EB2065-CH has one identified substitute: 1977739-1 from TE Connectivity ALCOSWITCH Switches. This substitution is valid based on the following alignment of critical parameters:

• Circuit Configuration: Both parts are SPDT with on-on switching function
• Electrical Ratings: Both rated 3A AC at 125V AC
• Mounting & Termination: Both feature panel mount, rear configuration with solder lug termination
• Electrical Life: Both rated for 25,000 cycles
• Compliance: Both are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity)
• HTSUS Classification: Identical tariff code (8536.50.9033)

Substitution is permissible where these core electrical and mechanical parameters match, regardless of differences in actuator type, color, or mechanical life specifications not shared between parts.

Parameter Comparison

Engineering Selection Recommendations

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

• Availability: EB2065-CH has 1046 units in stock; 1977739-1 has 964 units in stock
• Operating Temperature Range: The 1977739-1 supports an extended temperature range (-20°C to 80°C) compared to the EB2065-CH (-10°C to 70°C). Select 1977739-1 for applications requiring operation below -10°C or above 70°C
• Regulatory Status: Both parts carry identical ECCN and HTSUS classifications, with no trade compliance barriers to substitution
• Mechanical Life: The EB2065-CH specifies 100,000 mechanical cycles; the 1977739-1 does not provide this specification. For applications with high mechanical cycling requirements, the EB2065-CH may be preferred

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical SPDT circuit configuration, 3A/125V AC ratings, panel mount rear termination, solder lug connections, and 25,000 cycle electrical life. The parts are electrically and mechanically compatible for standard switching applications.

Q: What are the key differences between these parts?

A: The primary differences are operating temperature range (1977739-1 extends to -20°C and 80°C versus EB2065-CH at -10°C to 70°C), mechanical life specification (EB2065-CH specifies 100,000 cycles; 1977739-1 does not), and actuator design (EB2065-CH uses a round button; 1977739-1 uses a plunger for cap). Electrical performance and ratings are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8536.50.9033) classifications.

Q: Which part should I select for low-temperature applications?

A: The 1977739-1 supports operation down to -20°C, making it suitable for applications requiring temperatures below -10°C. The EB2065-CH is limited to -10°C minimum.

Q: Do these parts require any PCB layout modifications for substitution?

A: Both parts feature identical panel mount, rear termination with solder lug connections. No PCB layout changes are required for direct substitution.
