Key Parameters

Substitute Part Grouping Explanation

The substitute part 1977739-1 (TE Connectivity ALCOSWITCH Switches) qualifies as an equivalent based on the following matching parameters:

• Circuit configuration: Both parts are SPDT
• Switch function: Both are On-On configuration
• Current rating: Both rated 3A AC
• Voltage rating: Both rated 125V AC
• Mounting type: Both are panel mount, rear termination
• Termination style: Both use solder lug connections
• Electrical life: Both rated 25,000 cycles
• Compliance: Both are ROHS3 compliant with EAR99 ECCN classification

Substitution is valid when these core electrical and mechanical parameters are maintained across the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2065-CC and 1977739-1 meet the core electrical and mechanical requirements for SPDT pushbutton switch applications at 3A, 125V AC. Selection between these parts should be based on:

• Availability: EB2065-CC has 683 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-CC (-10°C ~ 70°C)
• Mechanical life specification: EB2065-CC specifies 100,000 cycles mechanical life; 1977739-1 does not provide this specification
• Compliance status: Both parts are ROHS3 compliant and carry EAR99 classification

Frequently Asked Questions (FAQ)

Q: Can 1977739-1 directly replace EB2065-CC in existing designs?

A: Yes, when the application requires SPDT on-on switching at 3A, 125V AC with solder lug termination and panel mount configuration. Both parts meet these electrical and mechanical specifications.

Q: What are the key differences between these parts?

A: The primary differences are operating temperature range (1977739-1 supports -20°C ~ 80°C versus EB2065-CC at -10°C ~ 70°C) and mechanical life specification (EB2065-CC specifies 100,000 cycles; 1977739-1 does not provide this value). Both maintain identical electrical ratings and termination style.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, have MSL rating of 1 (Unlimited), and share the same HTSUS code (8536.50.9033).

Q: What should be verified before substitution?

A: Confirm that the application circuit requires SPDT on-on configuration at 3A, 125V AC. Verify that the panel cutout dimensions and solder lug termination are compatible with the PCB or panel layout. If operating temperature range is critical, select based on the specific environmental requirements of the application.

Q: Are there any actuator or visual differences?

A: The EB2065-CC features a round button actuator with red color. The 1977739-1 uses a plunger-type actuator for cap mounting. These differences do not affect electrical substitution but may impact mechanical fit and user interface appearance.
