Key Parameters

Substitute Part Grouping Explanation

The EB2011P-CH has one identified equivalent: the 1977740-2 manufactured by TE Connectivity ALCOSWITCH Switches. This substitution is valid based on the following matching parameters:

• Circuit Configuration: Both parts are SPDT switches
• Electrical Ratings: Both rated for 3A AC at 125V AC
• Switch Function: Both provide On-Mom (momentary) operation
• Mounting Configuration: Both are panel-mount with rear termination
• Termination Style: Both use PC Pin termination
• Electrical Life: Both rated for 25,000 cycles
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited)
• HTSUS Classification: Identical tariff code (8536.50.9031)

Parameter Comparison

Engineering Selection Recommendations

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

• Availability: The 1977740-2 has 1031 units in stock versus 720 units for the EB2011P-CH
• Temperature Operating Range: The 1977740-2 supports -20°C to 80°C, providing wider environmental tolerance compared to the EB2011P-CH range of -10°C to 70°C
• Supply Chain Continuity: Both manufacturers maintain active production status, ensuring long-term availability

No technical performance degradation occurs when substituting either part for the other in applications within the overlapping operating temperature range (-10°C to 70°C).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical ratings (3A, 125V AC), circuit configuration (SPDT), switch function (On-Mom), mounting type (panel mount, rear), and termination style (PC Pin). Direct substitution is valid for applications operating within -10°C to 70°C.

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

A: The primary differences are manufacturer identity and operating temperature range. The 1977740-2 supports -20°C to 80°C versus -10°C to 70°C for the EB2011P-CH. The 1977740-2 features tactile/audible feedback, while the EB2011P-CH has epoxy sealed terminals. Both provide identical electrical performance and compliance certifications.

Q: Are there mechanical compatibility concerns with panel cutout dimensions?

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

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and share the same ECCN (EAR99) and HTSUS classification (8536.50.9031).

Q: Which part should be selected for new designs?

A: Selection should be based on supply availability, required operating temperature range, and preferred actuator characteristics. For applications requiring extended temperature operation below -10°C or above 70°C, the 1977740-2 is the appropriate choice.
