EB2011P-BF Equivalent & Substitute Parts
Part Overview
The EB2011P-BF 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 commonly used in control panels, industrial equipment, and consumer appliances requiring momentary switching functionality. Finding equivalent parts becomes necessary when managing inventory across multiple suppliers, addressing supply chain constraints, or standardizing component selections across product lines while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
The EB2011P-BF can be substituted with the 1977740-2 (TE Connectivity ALCOSWITCH Switches) based on the following critical parameters that define functional equivalence:
- Circuit Configuration: Both parts are SPDT switches
- Switch Function: Both operate as On-Mom (momentary) switches
- Current Rating: Both rated for 3A AC
- Voltage Rating: Both rated for 125V AC
- Mounting Type: Both are Panel Mount, Rear configuration
- Termination Style: Both use PC Pin termination
- Electrical Life: Both rated for 25,000 cycles
- Compliance: Both are ROHS3 Compliant with EAR99 ECCN classification
These parameters establish the substitution relationship as electrically and mechanically compatible for the intended application.

Engineering Selection Recommendations
Both the EB2011P-BF and 1977740-2 are active products with full ROHS3 compliance and identical electrical specifications for AC switching applications at 3A and 125V. Selection between these parts should be based on:
- Supply Availability: EB2011P-BF has 736 units in stock; 1977740-2 has 1031 units in stock
- Operating Temperature Requirements: The 1977740-2 supports an extended temperature range (-20°C ~ 80°C) compared to the EB2011P-BF (-10°C ~ 70°C), making it suitable for applications requiring broader thermal performance
- Mechanical Life Data: The EB2011P-BF specifies 100,000 mechanical cycles; the 1977740-2 does not provide this specification
- Regulatory Compliance: Both parts meet identical export control and tariff classifications
Frequently Asked Questions (FAQ)
Q: Can the 1977740-2 directly replace the EB2011P-BF in existing designs?
A: Yes. Both parts share identical electrical specifications (SPDT, 3A AC, 125V), switch function (On-Mom), mounting configuration (Panel Mount, Rear), and termination style (PC Pin). They are electrically and mechanically compatible for direct substitution in applications within the specified operating parameters.
Q: What are the key differences between these two parts?
A: The primary differences are operating temperature range (EB2011P-BF: -10°C ~ 70°C; 1977740-2: -20°C ~ 80°C) and mechanical life specification (EB2011P-BF: 100,000 cycles; 1977740-2: not specified). Both maintain identical electrical ratings and compliance certifications.
Q: Are there any packaging or inventory considerations?
A: Both parts are supplied in bulk packaging. Current inventory shows 736 units of EB2011P-BF and 1031 units of 1977740-2 available as new original stock.
Q: Do both parts meet the same regulatory requirements?
A: Yes. Both the EB2011P-BF and 1977740-2 are ROHS3 compliant, classified under ECCN EAR99, and share the same HTSUS code (8536.50.9031). Both have MSL rating of 1 (Unlimited).
Q: Which part should be selected for high-temperature applications?
A: The 1977740-2 is suitable for applications requiring operation up to 80°C, while the EB2011P-BF is rated to 70°C maximum. Application temperature requirements should determine the appropriate selection.
