PM-Y44P-C3 Equivalent & Substitute Parts

Part Overview

The PM-Y44P-C3 is an optical sensor module manufactured by Panasonic Industrial Automation Sales, designed for through-beam sensing applications with a 0.197" (5mm) sensing distance. This slot-type sensor features PNP output with selectable Dark-ON/Light-ON functionality, wire leads, and chassis mount configuration. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-Y44P-C3 is determined by the following critical parameters:

• Sensing Method: Through-beam optical sensing capability
• Output Configuration: PNP output type
• Mounting Type: Chassis mount with wire leads
• Response Time: 20µs performance specification
• Regulatory Compliance: RoHS compliance status

The PM-Y45-P-C3 qualifies as a substitute based on matching sensing method (through-beam), output type (PNP), mounting configuration (chassis mount with wire leads), and response time capability (20µs available). While the sensing distance differs (0.236" versus 0.197"), both operate within the through-beam optical sensor category with compatible electrical and mechanical interfaces.

Engineering Selection Recommendations

The PM-Y45-P-C3 is the designated substitute for the obsolete PM-Y44P-C3. Selection of this substitute is supported by:

• Product Status: The PM-Y45-P-C3 maintains active product status, ensuring continued availability and supply chain reliability
• Regulatory Compliance: Both parts meet RoHS requirements; the substitute achieves ROHS3 compliance, meeting current environmental standards
• Electrical Compatibility: Matching collector current specification (15 mA maximum) and response time capability (20µs) ensure functional equivalence in through-beam sensing applications
• Mechanical Interface: Both parts feature chassis mount configuration with wire leads, supporting direct integration into existing mechanical assemblies

The primary design consideration is the increased sensing distance of the PM-Y45-P-C3 (0.236" versus 0.197"), which may require validation in applications with tight spatial constraints or specific gap requirements.

Frequently Asked Questions (FAQ)

Q: Can the PM-Y45-P-C3 directly replace the PM-Y44P-C3 in all applications?

A: The PM-Y45-P-C3 is electrically and mechanically compatible as a substitute. However, the increased sensing distance (6mm versus 5mm) must be evaluated for your specific application geometry. If your system requires the exact 5mm sensing distance, physical validation is necessary.

Q: What is the difference between Dark-ON/Light-ON selectable and Open Collector output?

A: The PM-Y44P-C3 offers selectable output logic (Dark-ON or Light-ON), while the PM-Y45-P-C3 provides PNP Open Collector output. Both are PNP configurations; the substitute does not include the selectable logic feature. Verify your application's output logic requirement before substitution.

Q: Are there packaging differences between these parts?

A: Both parts use module packaging with wire leads and chassis mount configuration. The PM-Y44P-C3 specifies slot-type packaging, while the PM-Y45-P-C3 uses standard module packaging. Physical form factor should be verified against your mechanical assembly requirements.

Q: Why is the PM-Y44P-C3 listed as obsolete?

A: The PM-Y44P-C3 has reached end-of-life status. The PM-Y45-P-C3 represents the active product line continuation from Panasonic Industrial Automation Sales for through-beam optical sensing in this category.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The PM-Y44P-C3 is RoHS Compliant, and the PM-Y45-P-C3 achieves ROHS3 Compliant status, meeting current regulatory requirements for electronic components.
