PB1-3P2Y1CQ Equivalent & Substitute Parts

Part Overview

The PB1-3P2Y1CQ is a pushbutton switch manufactured by APEM Inc., featuring SPDT (Single Pole Double Throw) circuit configuration with a standard panel mount rear installation. This component is rated for 6A AC at 125V and 7A DC at 30V, with a round plunger actuator and PC pin termination. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs requiring compatible switching solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PB1-3P2Y1CQ is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Mounting type: Panel Mount, Rear
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia

Electrical Performance Parameters:

• AC voltage rating: minimum 125V
• DC voltage rating: minimum 30V
• AC current rating: minimum 6A
• DC current rating: minimum 7A

The substitute part E112LYCQE from C&K meets the mandatory mechanical and functional requirements. However, its electrical performance specifications differ from the original part, requiring evaluation based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

The E112LYCQE from C&K is mechanically and functionally compatible with the PB1-3P2Y1CQ for panel mount applications requiring SPDT momentary switching with round plunger actuation and PC pin termination. Both components are ROHS3 compliant and suitable for industrial control applications.

Selection of E112LYCQE is appropriate for applications where:

• AC current requirements do not exceed 4A
• DC current requirements do not exceed 4A
• Operating temperatures remain within -30°C to 75°C
• Electrical cycle life requirements do not exceed 40,000 cycles
• DC voltage margins of 2V below 30V are acceptable

Applications requiring the full electrical performance specifications of the original PB1-3P2Y1CQ (6A AC, 7A DC, 100,000 cycle life, 85°C upper temperature limit) should evaluate alternative suppliers for components meeting these higher performance thresholds.

Frequently Asked Questions (FAQ)

Q: Can E112LYCQE directly replace PB1-3P2Y1CQ in all applications?

A: E112LYCQE is mechanically and functionally compatible for panel mount installation. However, electrical performance differs. Substitution is valid only when application current requirements do not exceed 4A AC/DC, operating temperatures remain below 75°C, and cycle life requirements do not exceed 40,000 cycles.

Q: What are the key mechanical compatibility factors?

A: Both components share identical panel cutout dimensions (6.35mm circular), mounting configuration (panel mount rear), actuator type (round plunger), termination style (PC pin), and switch function (SPDT On-Mom). These parameters ensure mechanical interchangeability in panel installations.

Q: How do electrical ratings differ between these components?

A: The original PB1-3P2Y1CQ is rated for 6A AC and 7A DC at 125V AC and 30V DC respectively, with 100,000 cycle electrical life. The E112LYCQE is rated for 4A AC/DC at 125V AC and 28V DC, with 40,000 cycle electrical life. Applications must operate within E112LYCQE specifications for reliable performance.

Q: Are both components RoHS compliant?

A: Both PB1-3P2Y1CQ and E112LYCQE are ROHS3 compliant, meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What is the significance of product status differences?

A: PB1-3P2Y1CQ is obsolete and no longer manufactured by APEM Inc. E112LYCQE is active production from C&K, ensuring ongoing availability for new designs and system maintenance requiring compatible switching solutions.
