EB2011P-BG Equivalent & Substitute Parts

Part Overview

The EB2011P-BG 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 specified for standard switching applications requiring momentary on-off functionality with epoxy sealed terminals and a circular 6.35mm panel cutout. Finding equivalent substitute parts is necessary to ensure supply chain continuity, manage inventory across multiple suppliers, and maintain design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2011P-BG is determined by strict alignment of the following electrical and mechanical parameters:

• Circuit Configuration: Must be SPDT (Single Pole Double Throw)
• Switch Function: Must be On-Mom (momentary contact)
• Current Rating: Must support minimum 3A AC
• Voltage Rating: Must support minimum 125V AC
• Mounting Type: Must be Panel Mount, Rear
• Termination Style: Must be PC Pin
• Electrical Life: Must meet or exceed 25,000 cycles
• Compliance: Must maintain ROHS3 compliance and EAR99 classification

The substitute part 1977740-2 (TE Connectivity ALCOSWITCH Switches) meets all mandatory electrical parameters and maintains equivalent compliance certifications, making it a valid substitute within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011P-BG and 1977740-2 are active products with confirmed ROHS3 compliance and EAR99 classification. The substitute part 1977740-2 maintains electrical equivalence across all critical parameters: SPDT circuit, 3A AC at 125V, momentary function, PC pin termination, and 25,000 cycle electrical life. The substitute's operating temperature range (-20°C to 80°C) exceeds the primary part's specification (-10°C to 70°C), providing additional thermal margin. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings and identical HTSUS classification, confirming regulatory and supply chain compatibility. Selection between these parts should be based on availability, lead time, and procurement cost, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can 1977740-2 be used as a direct replacement for EB2011P-BG in existing designs?

A: Yes. Both parts share identical SPDT circuit configuration, 3A AC at 125V electrical ratings, momentary switch function, panel mount rear installation, and PC pin termination. Electrical life specifications are equivalent at 25,000 cycles. Physical panel cutout compatibility should be verified during integration, as the substitute's panel cutout dimensions are not specified in available data.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (NKK Switches vs. TE Connectivity ALCOSWITCH), actuator design (round button vs. plunger for cap), and operating temperature range (EB2011P-BG: -10°C to 70°C; 1977740-2: -20°C to 80°C). The substitute provides wider thermal operating range and tactile/audible feedback. Electrical and mechanical specifications remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both EB2011P-BG and 1977740-2 are ROHS3 compliant and carry EAR99 export classification with identical HTSUS code 8536.50.9031.

Q: What is the mechanical life difference between these parts?

A: Mechanical life data is provided only for the primary part EB2011P-BG (100,000 cycles). Mechanical life for 1977740-2 is not specified in available documentation. Both parts specify 25,000 cycles electrical life, which is the controlling parameter for switching applications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The substitute part 1977740-2 supports operation to 80°C, compared to the primary part's 70°C maximum. For applications requiring sustained operation above 70°C, the substitute provides additional thermal margin within its specified range.
