PB1-3PYZN Equivalent & Substitute Parts
Part Overview
The PB1-3PYZN is a pushbutton switch manufactured by APEM Inc., classified as SPDT (Single Pole Double Throw) with a current rating of 0.4VA at 20V AC/DC. This component features a standard panel mount configuration with rear termination using solder lugs and a circular 6.35mm panel cutout. The product is currently obsolete, with 981 pieces available in new original stock. Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation
Substitution eligibility for the PB1-3PYZN is determined by strict alignment of the following critical parameters:
- Circuit configuration: SPDT
- Current rating: 0.4VA (AC/DC)
- Voltage rating: 20V AC and 20V DC
- Mounting type: Panel Mount, Rear
- Panel cutout dimensions: Circular 6.35mm diameter
- Termination style: Solder Lug
- RoHS compliance: ROHS3 Compliant
The E112SYZBE manufactured by C&K meets all mandatory electrical and mechanical parameters required for direct substitution. Both parts share identical circuit topology, voltage and current ratings, mounting configuration, and panel interface specifications.

Engineering Selection Recommendations
The E112SYZBE serves as a direct functional equivalent to the PB1-3PYZN for applications requiring SPDT pushbutton switch functionality at 0.4VA and 20V ratings. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.
The E112SYZBE maintains active product status with 731 pieces in new original stock, providing supply continuity for the obsolete PB1-3PYZN. The substitute part operates within a slightly reduced temperature range (-30°C to 75°C versus -30°C to 85°C) and specifies 40,000 electrical cycles versus 100,000 cycles for the original part. These differences are within acceptable tolerances for equivalent component selection in standard panel-mount switch applications.
Frequently Asked Questions (FAQ)
Q: Can the E112SYZBE directly replace the PB1-3PYZN in existing designs?
A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), mounting type (Panel Mount, Rear), and panel cutout dimensions (6.35mm circular). Solder lug termination and actuator specifications are identical, enabling direct substitution without circuit modification.
Q: What are the differences between these two parts?
A: The E112SYZBE operates within a reduced temperature range (-30°C to 75°C versus -30°C to 85°C) and specifies 40,000 electrical cycles compared to 100,000 cycles for the PB1-3PYZN. The E112SYZBE includes process sealing as an additional feature. These differences do not affect compatibility for standard panel-mount switch applications.
Q: Why is the PB1-3PYZN listed as obsolete?
A: The PB1-3PYZN has been discontinued by APEM Inc. The E112SYZBE from C&K maintains active production status and provides equivalent functionality for new designs and replacement applications.
Q: Are both parts RoHS and REACH compliant?
A: Yes. Both the PB1-3PYZN and E112SYZBE are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
Q: What packaging options are available?
A: The PB1-3PYZN is available in standard packaging. The E112SYZBE is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
