EB2011G-CA Equivalent & Substitute Parts

Part Overview

The EB2011G-CA is an SPDT pushbutton switch manufactured by NKK Switches, rated for 0.4VA at 28V AC/DC. This panel-mount rear component features a circular 6.35mm diameter cutout, solder lug termination, and epoxy sealed terminals. The switch is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1977737-2 (TE Connectivity ALCOSWITCH Switches) qualifies as an equivalent based on the following criteria:

Matching Parameters:

• Circuit configuration: SPDT (identical)
• Switch function: On-Mom (identical)
• Mounting type: Panel Mount, Rear (identical)
• Termination style: Solder Lug (identical)
• Electrical life: 50,000 Cycles (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Regulatory classification: HTSUS 8536.50.9031 (identical)

Electrical Compatibility: The 1977737-2 operates at 60mA DC with 30V DC rating, which accommodates the EB2011G-CA's 0.4VA (approximately 14.3mA at 28V) requirement. The higher voltage and current ratings of the substitute provide operational margin within the same electrical class.

Mechanical Compatibility: Both switches employ solder lug termination and rear panel mounting configuration, enabling direct mechanical integration into existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011G-CA and 1977737-2 maintain active product status with ROHS3 compliance and identical electrical life ratings. The 1977737-2 provides extended operating temperature range (-20°C to 80°C versus -10°C to 70°C), which may be advantageous in applications requiring broader thermal performance. Current and voltage ratings of the substitute exceed the main part specifications, ensuring compatibility within the same electrical circuit class. Selection between these parts should be based on availability, lead time, and specific thermal or environmental requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 directly replace the EB2011G-CA in existing designs?

A: Yes. Both switches share identical SPDT circuit configuration, On-Mom function, panel mount rear configuration, and solder lug termination. The 1977737-2's higher current and voltage ratings are compatible with circuits designed for the EB2011G-CA.

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

A: The EB2011G-CA is rated for 0.4VA at 28V AC/DC. The 1977737-2 is rated for 60mA DC at 30V DC. The substitute's ratings exceed the main part, providing operational margin in DC applications.

Q: Are there mechanical compatibility concerns?

A: No. Both switches employ identical mounting type (Panel Mount, Rear), termination style (Solder Lug), and circuit configuration (SPDT). Mechanical integration is direct.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both are ROHS3 compliant and share the same HTSUS classification (8536.50.9031). Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part has better temperature performance?

A: The 1977737-2 operates across -20°C to 80°C, compared to the EB2011G-CA's -10°C to 70°C range. The substitute provides 10°C additional margin at both temperature extremes.

Q: Are there differences in mechanical life between these switches?

A: Mechanical life data is not provided for the 1977737-2. Both switches specify 50,000 electrical life cycles.
