EB2011P-CC Equivalent & Substitute Parts

Part Overview

The EB2011P-CC is an SPDT pushbutton switch manufactured by NKK Switches, rated for 3A at 125V AC with panel mount rear termination. This component is designed for standard switching applications requiring momentary on-off functionality with PC pin termination and epoxy sealed terminals. The part is currently active in production with 868 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configuration, and mechanical mounting compatibility are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2011P-CC is determined by the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw) — must match exactly
• Current Rating: 3A AC — must meet or exceed this specification
• Voltage Rating: 125V AC — must meet or exceed this specification
• Switch Function: On-Mom (momentary) — must match exactly
• Mounting Type: Panel Mount, Rear — must match exactly
• Termination Style: PC Pin — must match exactly
• Electrical Life: Minimum 25,000 cycles — must meet or exceed
• RoHS Compliance: ROHS3 Compliant — required for regulatory alignment
• Product Status: Active — ensures ongoing availability and support

The substitute part 1977740-2 (TE Connectivity ALCOSWITCH Switches) meets all critical electrical and mechanical parameters required for direct substitution in applications using the EB2011P-CC.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011P-CC and 1977740-2 are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Availability: EB2011P-CC has 868 units in stock; 1977740-2 has 1031 units in stock
• Temperature Operating Range: The 1977740-2 provides an extended operating range (-20°C ~ 80°C) compared to the EB2011P-CC (-10°C ~ 70°C), making it suitable for applications requiring broader thermal performance
• Regulatory Status: Both parts maintain equivalent compliance certifications (ROHS3, EAR99, HTSUS 8536.50.9031)
• Actuator Design: EB2011P-CC features a round button actuator; 1977740-2 uses a plunger-type actuator, which may affect ergonomic or panel integration considerations

Frequently Asked Questions (FAQ)

Q: Can 1977740-2 directly replace EB2011P-CC 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. Physical panel cutout compatibility should be verified during integration.

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

A: The primary differences are: (1) Operating temperature range — 1977740-2 extends to -20°C ~ 80°C versus EB2011P-CC at -10°C ~ 70°C; (2) Actuator type — EB2011P-CC uses a round button while 1977740-2 uses a plunger design; (3) Mechanical life data — EB2011P-CC specifies 100,000 cycles while 1977740-2 does not provide this specification.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS code (8536.50.9031). Moisture sensitivity levels are identical (MSL 1 — Unlimited).

Q: Which part should be selected for high-temperature applications?

A: The 1977740-2 is suitable for applications requiring operation above 70°C, as it is rated to 80°C maximum. The EB2011P-CC is limited to 70°C maximum operating temperature.

Q: Are panel cutout dimensions compatible?

A: The EB2011P-CC specifies a circular 6.35mm diameter panel cutout. The 1977740-2 does not provide panel cutout dimension data in the available specifications. Physical verification is required before substitution in existing panel assemblies.
