EB2011P-CB Equivalent & Substitute Parts

Part Overview

The EB2011P-CB is an active SPDT pushbutton switch manufactured by NKK Switches, designed for panel mount rear installation with a 3A AC rating at 125V. This component is used in applications requiring standard pushbutton switching with momentary on-off functionality. Substitute parts are identified when equivalent electrical ratings, circuit configurations, and mechanical mounting specifications are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2011P-CB is determined by strict equivalence in the following parameters:

• Circuit Type: SPDT configuration required
• Electrical Ratings: 3A AC at 125V minimum
• Switch Function: Momentary (On-Mom) operation
• Mounting Configuration: Panel mount, rear installation with PC pin termination
• Electrical Life: 25,000 cycles minimum
• Compliance: ROHS3 compliance and active product status

The substitute part 1977740-2 (TE Connectivity ALCOSWITCH Switches) meets all mandatory substitution criteria. Differences in mechanical life specification, operating temperature range, and actuator design do not preclude substitution when electrical and functional parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011P-CB and 1977740-2 are active products with ROHS3 compliance and equivalent electrical specifications. Selection between these parts should be based on:

• Availability: EB2011P-CB has 1043 units in stock; 1977740-2 has 1031 units in stock
• Operating Environment: The 1977740-2 supports an extended temperature range (-20°C to 80°C) compared to the EB2011P-CB (-10°C to 70°C). Applications requiring operation below -10°C or above 70°C require the 1977740-2
• Mechanical Life: EB2011P-CB specifies 100,000 mechanical cycles; 1977740-2 does not specify this parameter. For applications with high mechanical cycling requirements, the EB2011P-CB may be preferred
• Compliance Status: Both parts maintain ROHS3 compliance. REACH status differs (EB2011P-CB: REACH Unaffected; 1977740-2: Vendor Undefined); verify REACH requirements for your application jurisdiction

Frequently Asked Questions (FAQ)

Q: Can 1977740-2 directly replace EB2011P-CB in existing designs?

A: Yes, provided the operating temperature range of the application falls within -20°C to 80°C. Both parts share identical electrical ratings (3A, 125V AC), SPDT circuit configuration, momentary function, and PC pin termination. Panel mount rear installation is equivalent.

Q: What is the difference in actuator design between these parts?

A: EB2011P-CB features a round button actuator with white color. 1977740-2 uses a plunger-type actuator. Both are functionally equivalent for SPDT momentary switching. Verify panel cutout compatibility; EB2011P-CB specifies circular 6.35mm diameter cutout; 1977740-2 does not specify panel cutout dimensions.

Q: Are there electrical performance differences?

A: No. Both parts are rated for 3A AC at 125V with 25,000 electrical life cycles. The EB2011P-CB specifies 100,000 mechanical life cycles; the 1977740-2 does not provide this specification.

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

A: The 1977740-2 supports operation to -20°C, compared to -10°C for the EB2011P-CB. For applications below -10°C, use 1977740-2.

Q: Are both parts RoHS compliant?

A: Yes. Both EB2011P-CB and 1977740-2 are ROHS3 compliant. Verify REACH compliance requirements with your supply chain; EB2011P-CB is REACH Unaffected, while 1977740-2 is listed as Vendor Undefined.
