EB2061-BC Equivalent & Substitute Parts

Part Overview

The EB2061-BC is a pushbutton switch manufactured by NKK Switches, classified as a DPDT (Double Pole Double Throw) standard panel mount switch with rear termination. It is rated for 3A AC at 125V and features a red round button actuator with solder lug termination and epoxy sealed terminals. The part is currently active in production with 891 units in stock.

Substitute parts are identified when equivalent electrical ratings, circuit configurations, and mechanical mounting specifications are maintained across different manufacturers. This ensures functional interchangeability in applications where the EB2061-BC may be unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

The MPS-203R from TE Connectivity ALCOSWITCH Switches qualifies as a direct substitute based on the following matched parameters:

• Circuit Configuration: Both parts are DPDT
• Current Rating: Both rated 3A AC
• Voltage Rating: Both rated 125V AC
• Switch Function: Both are On-Mom (momentary)
• Mounting Type: Both are Panel Mount, Rear
• Termination Style: Both use Solder Lug
• Electrical Life: Both rated 25,000 cycles
• RoHS Compliance: Both ROHS3 Compliant
• MSL Rating: Both MSL 1 (Unlimited)

These parameters define the substitution criteria for this product category. Parts matching all these specifications are electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2061-BC and MPS-203R are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Availability: Current inventory levels (EB2061-BC: 891 units; MPS-203R: 899 units)
• Operating Temperature Requirements: The MPS-203R supports a wider temperature range (-20°C ~ 80°C) compared to the EB2061-BC (-10°C ~ 70°C). Applications requiring operation below -10°C or above 70°C should specify the MPS-203R
• Regulatory Status: Both parts are ROHS3 compliant and carry EAR99 ECCN classification, suitable for equivalent regulatory environments
• Supply Chain Continuity: Either part may be selected as a primary or secondary source given equivalent electrical and mechanical characteristics

Frequently Asked Questions (FAQ)

Q: Can MPS-203R be used as a direct replacement for EB2061-BC?

A: Yes. Both parts share identical circuit configuration (DPDT), current rating (3A AC), voltage rating (125V AC), switch function (On-Mom), mounting type (Panel Mount, Rear), termination style (Solder Lug), and electrical life (25,000 cycles). They are electrically and mechanically interchangeable.

Q: What are the differences between these two parts?

A: The primary differences are operating temperature range (EB2061-BC: -10°C ~ 70°C; MPS-203R: -20°C ~ 80°C), mechanical life specification (EB2061-BC: 100,000 cycles; MPS-203R: not specified), and actuator design (EB2061-BC: round button; MPS-203R: plunger for cap). These differences do not affect electrical substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both EB2061-BC and MPS-203R are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should I select for applications with extreme temperature requirements?

A: The MPS-203R supports operation from -20°C to 80°C, providing a wider temperature envelope than the EB2061-BC (-10°C to 70°C). For applications requiring operation outside the EB2061-BC range, the MPS-203R is the appropriate selection.

Q: Do these parts require any design modifications for substitution?

A: No design modifications are required. Both parts use identical solder lug termination, panel mount rear configuration, and DPDT circuit topology. Direct substitution is possible without PCB or assembly changes.
