EB2061P-CA Equivalent & Substitute Parts

Part Overview

The EB2061P-CA is an active DPDT pushbutton switch manufactured by NKK Switches, rated for 3A at 125V AC. This panel-mount rear component features a round black button actuator with PC pin termination and epoxy sealed terminals. The switch is designed for standard on-momentary applications requiring 100,000 mechanical cycles and 25,000 electrical cycles. Substitute parts are identified when equivalent electrical ratings, circuit configuration, mounting type, and termination style are maintained across the product lifecycle and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both EB2061P-CA and 1977740-4 meet the core electrical and mechanical requirements for DPDT pushbutton switch applications at 3A/125V AC. Selection between these parts should be based on:

• Product availability and lead time requirements
• Operating temperature range: The 1977740-4 supports -20°C to 80°C versus -10°C to 70°C for the EB2061P-CA
• Mechanical life specification: The EB2061P-CA specifies 100,000 mechanical cycles; the 1977740-4 does not provide this specification
• Both parts maintain ROHS3 compliance and identical electrical life ratings of 25,000 cycles
• Both are classified under identical HTSUS and ECCN codes

Frequently Asked Questions (FAQ)

Q: What makes 1977740-4 a valid substitute for EB2061P-CA?

A: Both parts share identical circuit configuration (DPDT), current rating (3A AC), voltage rating (125V AC), switch function (on-momentary), mounting type (panel mount, rear), termination style (PC pin), and electrical life (25,000 cycles). These parameters define functional equivalence for this switch category.

Q: Are there differences in operating temperature ranges?

A: Yes. The EB2061P-CA operates from -10°C to 70°C, while the 1977740-4 operates from -20°C to 80°C. Selection should account for the specific application temperature requirements.

Q: What is the significance of mechanical life specifications?

A: The EB2061P-CA specifies 100,000 mechanical cycles. The 1977740-4 does not provide a mechanical life specification in the available data. Applications requiring documented mechanical life performance should reference the EB2061P-CA specification.

Q: Are both parts RoHS compliant?

A: Yes. Both EB2061P-CA and 1977740-4 are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability is determined by circuit configuration, electrical ratings, mounting type, and termination style. Both parts match these core parameters. Physical dimensions and actuator design differences should be verified against specific PCB layout and panel cutout requirements before implementation.
