PM-Y54P Equivalent & Substitute Parts

Part Overview

The PM-Y54P is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type module with selectable PNP dark-ON/light-ON output configuration. This component operates at a 0.197" (5mm) sensing distance and is classified as an unamplified optical sensor with wire lead connections for chassis mounting applications.

The PM-Y54P is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new design implementations where this sensing distance and output configuration are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-Y54P is evaluated based on the following critical parameters that define functional equivalence:

Sensing Method: Through-beam operation is the primary functional requirement. Substitute parts must maintain this detection principle.

Output Configuration: PNP output with open collector topology is essential for circuit compatibility. The PM-Y54P features selectable dark-ON/light-ON functionality; substitute parts must support PNP output.

Sensing Distance: The 0.197" (5mm) sensing distance is a key mechanical and optical specification. Substitute parts with different sensing distances (such as 0.236" / 6mm) represent a different product category and require application re-evaluation.

Response Time: The 20µs response time establishes the switching speed requirement. Substitute parts must meet or exceed this performance.

Operating Temperature Range: The -25°C ~ 55°C operating range defines environmental suitability. Substitute parts must support this temperature envelope.

Electrical Ratings: Maximum collector current (15 mA), forward current (50 mA), and collector-emitter breakdown voltage (30 V) establish load-driving capability and circuit protection requirements.

Mounting and Packaging: Chassis mount configuration with wire leads and slot-type module form factor are mechanical constraints.

The PM-Y45-P is listed as a substitute part. However, this part exhibits a different sensing distance (0.236" / 6mm versus 0.197" / 5mm), which represents a functional difference requiring application-specific evaluation rather than direct equivalence.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PM-Y54P is obsolete, making the PM-Y45-P the active alternative from Panasonic Industrial Automation Sales. The PM-Y45-P maintains active product status with current inventory availability (78,868 pcs), ensuring supply chain continuity.

Compliance and Certifications: Both parts are RoHS compliant. The PM-Y45-P carries ROHS3 Compliant status, representing current regulatory alignment. Both parts share identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications, confirming equivalent regulatory treatment.

Functional Differences: The primary distinction between these parts is the sensing distance specification. The PM-Y54P operates at 0.197" (5mm), while the PM-Y45-P operates at 0.236" (6mm). This 0.039" (1mm) difference in sensing distance represents a distinct optical and mechanical design and must be evaluated against specific application requirements.

Output Configuration: Both parts feature PNP output with open collector topology. The PM-Y54P includes selectable dark-ON/light-ON functionality, while the PM-Y45-P specifies PNP - Open Collector output. Circuit compatibility depends on whether the application requires the selectable output mode of the PM-Y54P.

Electrical and Thermal Performance: Both parts share identical response time (20µs primary specification), operating temperature range (-25°C ~ 55°C), and mounting configuration. The PM-Y45-P supports dual response time options (20µs, 80µs), providing additional flexibility.

Frequently Asked Questions (FAQ)

Q: Can the PM-Y45-P directly replace the PM-Y54P in existing applications?

A: Direct replacement depends on sensing distance tolerance. The PM-Y45-P operates at 0.236" (6mm) versus the PM-Y54P at 0.197" (5mm). If the application slot width and object detection position accommodate the 1mm difference, substitution is feasible. If the slot width is precisely 5mm or the detection position is critical, the sensing distance difference may prevent direct substitution.

Q: Are the electrical characteristics compatible between these parts?

A: Both parts feature PNP output with open collector configuration and share identical response time (20µs) and operating temperature range (-25°C ~ 55°C). Circuit-level compatibility is established for standard PNP sensor applications. The PM-Y54P's selectable dark-ON/light-ON feature should be verified against the PM-Y45-P's fixed output configuration for specific logic requirements.

Q: What is the significance of the different response time specifications for the PM-Y45-P?

A: The PM-Y45-P lists response time as 20µs, 80µs, indicating dual-mode operation or selectable response characteristics. The PM-Y54P specifies 20µs. Both parts meet the 20µs requirement, ensuring compatibility for applications requiring this switching speed.

Q: Are both parts RoHS compliant?

A: Yes. The PM-Y54P is RoHS Compliant, and the PM-Y45-P is ROHS3 Compliant. Both meet current RoHS regulatory requirements. The ROHS3 designation on the PM-Y45-P reflects current compliance standards.

Q: What packaging differences exist between these parts?

A: Both parts are supplied as modules with wire leads for chassis mounting. The PM-Y54P specifies slot-type module configuration, while the PM-Y45-P specifies module configuration without explicit slot-type designation. Physical form factor compatibility should be confirmed for mechanical fit in existing mounting structures.

Q: Is the PM-Y45-P available for immediate procurement?

A: The PM-Y45-P is listed as active product status with 78,868 pcs new original in stock, indicating current availability. The PM-Y54P is obsolete with no ongoing production.
