PB1-3PYCB Equivalent & Substitute Parts

Part Overview

The PB1-3PYCB is a pushbutton switch manufactured by APEM Inc., featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 20V. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch is designed for panel mount rear installation with a standard round plunger actuator and PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PB1-3PYCB is determined by strict alignment of the following critical parameters:

• Circuit configuration must be SPDT
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must support minimum 20V AC and 20V DC
• Mounting type must be Panel Mount, Rear
• Termination style must be PC Pin
• Panel cutout dimensions must be Circular - 6.35mm Dia
• RoHS3 compliance required

The E112LYCBE from C&K meets all substitution criteria across these parameters, enabling direct functional replacement in applications requiring the PB1-3PYCB specification.

Parameter Comparison

Engineering Selection Recommendations

The E112LYCBE serves as a direct functional equivalent to the obsolete PB1-3PYCB. Both components maintain identical electrical specifications (SPDT circuit, 0.4VA, 20V AC/DC), mechanical interface (Panel Mount Rear, PC Pin termination, 6.35mm circular cutout), and regulatory compliance (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The E112LYCBE is currently in active production status, ensuring supply chain continuity and availability for replacement and new applications. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating equivalent handling and storage requirements.

Differences in operating temperature range (-30°C ~ 75°C for E112LYCBE versus -30°C ~ 85°C for PB1-3PYCB) and electrical life (40,000 cycles versus 100,000 cycles) should be evaluated against specific application requirements. Applications operating above 75°C or requiring extended cycle life beyond 40,000 cycles may require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the E112LYCBE directly replace the PB1-3PYCB in existing designs?

A: Yes. Both components share identical circuit configuration (SPDT), current rating (0.4VA AC/DC), voltage ratings (20V), mounting interface (Panel Mount Rear), termination style (PC Pin), and panel cutout dimensions (6.35mm circular). Physical and electrical compatibility is confirmed.

Q: What are the key differences between these components?

A: Operating temperature range differs (E112LYCBE: -30°C ~ 75°C; PB1-3PYCB: -30°C ~ 85°C) and electrical life differs (E112LYCBE: 40,000 cycles; PB1-3PYCB: 100,000 cycles). Applications must confirm these parameters are acceptable for their specific operating environment and duty cycle.

Q: Why is the PB1-3PYCB listed as obsolete?

A: The PB1-3PYCB is no longer in active production. The E112LYCBE from C&K provides equivalent functionality with active manufacturing status, ensuring long-term supply availability.

Q: Are there packaging differences between these components?

A: The PB1-3PYCB is supplied with standard packaging, while the E112LYCBE is supplied in bulk packaging. Both are suitable for PCB assembly and panel mount applications.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level is 1 (Unlimited) for both.
