EB2061P-CG Equivalent & Substitute Parts

Part Overview

The EB2061P-CG is an active DPDT pushbutton switch manufactured by NKK Switches, rated for 3A at 125V AC. This panel-mount rear component features a round blue button actuator with PC pin termination and epoxy sealed terminals. The switch is designed for standard on-momentary applications with 100,000 mechanical cycles and 25,000 electrical cycles. Finding equivalent substitute parts is necessary to ensure supply chain continuity, manage inventory across multiple suppliers, and maintain design flexibility in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2061P-CG is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be DPDT
• Current rating must be 3A (AC)
• Voltage rating must be 125V AC
• Switch function must be On-Mom
• Mounting type must be Panel Mount, Rear
• Termination style must be PC Pin
• Electrical life must meet or exceed 25,000 cycles
• RoHS3 compliance is required
• Product status must be Active

The substitute part 1977740-4 (TE Connectivity ALCOSWITCH Switches) meets all mandatory electrical and mechanical parameters for direct substitution in the EB2061P-CG application.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2061P-CG and 1977740-4 are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supplier relationship and pricing terms
• Operating temperature requirements (1977740-4 supports -20°C ~ 80°C versus EB2061P-CG at -10°C ~ 70°C)
• Mechanical life specifications (EB2061P-CG specifies 100,000 cycles; 1977740-4 does not specify mechanical life in available data)

Both parts carry EAR99 export classification and are subject to identical HTSUS tariff codes, making them equivalent for regulatory and compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can 1977740-4 be used as a direct replacement for EB2061P-CG?

A: Yes. Both parts share identical electrical ratings (3A, 125V AC, DPDT), switch function (On-Mom), mounting configuration (Panel Mount, Rear), and termination style (PC Pin). Both are ROHS3 compliant and active products with 25,000 electrical cycle ratings.

Q: What are the differences between these two parts?

A: The primary differences are operating temperature range (1977740-4 extends to -20°C and 80°C versus EB2061P-CG at -10°C to 70°C) and mechanical life specification (EB2061P-CG specifies 100,000 cycles; 1977740-4 does not provide this specification). Actuator design differs (round button versus plunger for cap), and feature sets vary (epoxy sealed terminals versus tactile/audible feedback).

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS codes (8536.50.9031). Both have MSL rating of 1 (Unlimited).

Q: Which part should be selected for extreme temperature applications?

A: The 1977740-4 supports a wider operating temperature range (-20°C ~ 80°C) compared to the EB2061P-CG (-10°C ~ 70°C). Selection depends on specific application temperature requirements.

Q: Are inventory levels a consideration?

A: Yes. Current inventory shows 752 pcs of EB2061P-CG and 844 pcs of 1977740-4 in stock. Availability may influence selection based on project timelines and volume requirements.
