EB2011P-CE Equivalent & Substitute Parts

Part Overview

The EB2011P-CE is an SPDT pushbutton switch manufactured by NKK Switches, rated for 3A at 125V AC. This panel-mount, rear-termination switch features a yellow round button actuator with epoxy sealed PC pin terminals. The product is Active status with 991 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configuration, and mechanical mounting specifications align with the original component, enabling direct replacement in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

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

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

The substitute part 1977740-2 (TE Connectivity ALCOSWITCH Switches) meets all mandatory electrical parameters and mechanical mounting requirements, qualifying it as a direct equivalent for component replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011P-CE and 1977740-2 are Active status products with ROHS3 compliance and EAR99 ECCN classification. Selection between these components should be based on:

• Inventory Availability: EB2011P-CE has 991 units in stock; 1977740-2 has 1031 units in stock
• Compliance Requirements: Both parts satisfy ROHS3 and MSL 1 (Unlimited) moisture sensitivity specifications
• Operating Environment: The 1977740-2 supports an extended temperature range (-20°C ~ 80°C) compared to the EB2011P-CE (-10°C ~ 70°C), providing additional thermal margin for applications operating at temperature extremes
• Mechanical Life: The EB2011P-CE specifies 100,000 mechanical cycles; the 1977740-2 specification is not provided in available data

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical ratings (3A, 125V AC, SPDT), switch function (On-Mom), mounting configuration (Panel Mount, Rear), and termination style (PC Pin). Electrical life specifications are equivalent at 25,000 cycles. No circuit redesign is required.

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

A: The primary differences are actuator design (EB2011P-CE uses a round button; 1977740-2 uses a plunger for cap), operating temperature range (1977740-2 extends to -20°C and +80°C versus -10°C to +70°C), and mechanical life specification (EB2011P-CE specifies 100,000 cycles; 1977740-2 data not provided). Both feature identical electrical performance and compliance status.

Q: Are there any panel cutout dimension differences?

A: The EB2011P-CE specifies a circular 6.35mm diameter panel cutout. The 1977740-2 panel cutout dimensions are not provided in available specifications. Physical verification is necessary before installation if panel modifications have already been completed.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EB2011P-CE and 1977740-2 are ROHS3 compliant, carry EAR99 ECCN classification, and maintain MSL 1 (Unlimited) moisture sensitivity level. REACH status differs: EB2011P-CE is REACH Unaffected; 1977740-2 is Vendor Undefined.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard operating conditions within -10°C to +70°C, either part is suitable. For applications requiring extended temperature operation or higher mechanical cycle counts, verify the 1977740-2 mechanical life specification with the manufacturer before design commitment.
