PB400EEQX Equivalent & Substitute Parts

Part Overview

The PB400EEQX is a pushbutton switch manufactured by E-Switch, configured as a DPST (Double Pole Single Throw) standard through-hole component with right-angle mounting. This switch is rated for 3A DC at 30V and features a plunger actuator without marking. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical ratings, circuit configuration, mounting type, and termination style are maintained across the product series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the PB400 series maintain electrical and mechanical compatibility with the PB400EEQX based on the following criteria:

Critical Parameters for Substitution:

• Circuit configuration (DPST)
• Current rating (3A DC)
• Voltage rating (30V DC)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Switch function (Off-On)
• Operating temperature range (-5°C to 60°C)
• Electrical life (6,000 Cycles)

Variable Parameters (Non-Critical for Substitution):

• Actuator type (Plunger vs. Round Button)
• Actuator color
• Actuator marking

The PB400EEQR1BLK is classified as a manufacturer-recommended substitute because it maintains all critical electrical and mechanical parameters while differing only in actuator design and color, which do not affect circuit performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both PB400EEQX and PB400EEQR1BLK are Active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. Selection between these parts should be based on actuator form factor requirements:

• PB400EEQX is specified when a plunger-style actuator without color marking is required.
• PB400EEQR1BLK is specified when a round button actuator with black color is required.

Both parts share identical electrical ratings, circuit topology, mounting configuration, and environmental specifications. The choice between them does not affect circuit performance or PCB layout compatibility, only the physical actuator interface and user interaction characteristics.

Frequently Asked Questions (FAQ)

Q: Can PB400EEQR1BLK replace PB400EEQX in an existing design?

A: Yes. Both parts maintain identical electrical specifications (3A DC, 30V DC, DPST configuration), mounting type (Through Hole, Right Angle), and termination style (PC Pin). The difference is limited to actuator design and color, which do not affect circuit functionality or board-level compatibility.

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

A: The primary differences are actuator type (Plunger vs. Round Button) and actuator color (unspecified vs. Black). All electrical parameters, voltage/current ratings, circuit configuration, and environmental specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both PB400EEQX and PB400EEQR1BLK are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for these switches?

A: Both parts operate within -5°C to 60°C.

Q: What is the electrical life rating?

A: Both parts are rated for 6,000 electrical cycles.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Bulk packaging.
