PM-Y44-C3 Equivalent & Substitute Parts

Part Overview

The PM-Y44-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 NPN-output sensor features selectable Dark-ON/Light-ON operation and is housed in a slot-type module with wire leads for chassis mounting. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

The PM-Y45-C3 qualifies as a substitute for the PM-Y44-C3 based on the following alignment of critical parameters:

Shared Functional Characteristics:

• Sensing method: Through-Beam (both models)
• Output configuration: NPN-based (both models)
• Mounting type: Chassis Mount (both models)
• Package type: Module with Wire Leads (both models)
• Response time: 20µs (both models support this specification)
• Moisture sensitivity: MSL 1 (Unlimited) (both models)
• RoHS compliance: Both models meet environmental standards

Substitution Basis: The PM-Y45-C3 operates within compatible electrical parameters and maintains the same sensing methodology. The primary difference is an increased sensing distance of 0.236" (6mm) versus the original 0.197" (5mm), which represents a functional enhancement rather than a limitation. Both sensors are NPN-output through-beam modules suitable for slot-type mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The PM-Y45-C3 is the designated substitute for the obsolete PM-Y44-C3. Selection of the PM-Y45-C3 is supported by:

• Product Status Alignment: The PM-Y45-C3 is an active product with current manufacturing support, whereas the PM-Y44-C3 is obsolete and subject to supply discontinuation.
• Compliance Standards: Both components meet RoHS requirements. The PM-Y45-C3 achieves ROHS3 compliance, representing current regulatory alignment.
• Electrical Compatibility: Both sensors maintain NPN output configuration and 15 mA maximum collector current, ensuring circuit-level compatibility in most applications.
• Sensing Methodology: Both employ through-beam sensing with identical response time at 20µs, preserving detection performance characteristics.
• Physical Mounting: Both utilize chassis mount configuration with wire lead modules, supporting equivalent mechanical integration.

The increased sensing distance of the PM-Y45-C3 (6mm versus 5mm) provides extended detection range, which is operationally beneficial in most slot-type sensing applications.

Frequently Asked Questions (FAQ)

Q: Can the PM-Y45-C3 directly replace the PM-Y44-C3 in existing designs?

A: Yes. Both sensors share NPN output configuration, through-beam sensing methodology, 15 mA collector current rating, 20µs response time, and chassis mount packaging. The PM-Y45-C3 provides equivalent electrical and mechanical compatibility.

Q: What is the primary difference between these two models?

A: The sensing distance differs: PM-Y44-C3 operates at 0.197" (5mm), while PM-Y45-C3 operates at 0.236" (6mm). This represents an extended detection range in the substitute model.

Q: Does the output configuration difference affect substitution?

A: The PM-Y44-C3 features selectable Dark-ON/Light-ON operation, while the PM-Y45-C3 provides NPN Open Collector output. Both are NPN-based configurations. Circuit design must account for the PM-Y45-C3's fixed open collector output rather than selectable operation.

Q: Are there supply voltage differences?

A: The PM-Y45-C3 specifies 5V ~ 24V supply voltage range with documented operating temperature of -25°C ~ 55°C. The PM-Y44-C3 does not provide these specifications in available documentation. Verify supply voltage compatibility with your system design.

Q: Is the PM-Y45-C3 available in the same packaging?

A: Both use Module with Wire Leads packaging for chassis mounting. The PM-Y45-C3 is supplied in Bulk packaging, whereas the PM-Y44-C3 packaging type is not specified. Both support equivalent mechanical integration.

Q: What is the inventory status of these components?

A: PM-Y44-C3 inventory shows 1071 pieces available as new original stock. PM-Y45-C3 shows 924 pieces available as new original stock. Both are currently in stock.
