Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM-K44P-C3 is determined by the following critical parameters:

Sensing method compatibility: Both the main part and substitute must operate as through-beam optical sensors.

Output configuration: The substitute must support PNP output with open collector topology to maintain circuit compatibility.

Response time: The substitute response time of 20µs or 80µs remains within acceptable operational windows for the target application class.

Operating temperature range: The substitute must maintain the -25°C ~ 55°C operating envelope.

Mounting configuration: Chassis mount compatibility with module and wire lead packaging ensures mechanical fit.

Regulatory compliance: RoHS and ECCN classifications must align with the original component specifications.

The PM-K45-P-C3 meets these substitution criteria as an active product within the Panasonic PM-series optical sensor family, offering enhanced sensing distance capability while maintaining core functional and electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The PM-K45-P-C3 is classified as an active product, ensuring ongoing availability and manufacturing support compared to the obsolete PM-K44P-C3. Both components maintain identical ECCN (EAR99) and HTSUS classifications, confirming regulatory alignment for export and trade purposes.

The PM-K45-P-C3 demonstrates enhanced RoHS compliance status (ROHS3) relative to the original component, meeting current environmental and material restriction standards. Moisture sensitivity levels remain equivalent at MSL 1 (Unlimited), indicating identical handling and storage requirements.

The sensing distance differential of 0.039" (1mm) between the two models reflects the primary design evolution within the PM-series family. The substitute's extended sensing range accommodates applications requiring increased detection margins while maintaining identical response time performance at 20µs.

Frequently Asked Questions (FAQ)

Q: Can the PM-K45-P-C3 directly replace the PM-K44P-C3 in existing installations?

A: Direct mechanical and electrical substitution is supported. The PM-K45-P-C3 maintains chassis mount compatibility and PNP output configuration. The increased sensing distance (6mm versus 5mm) may require mechanical repositioning depending on application geometry. Verify that the extended sensing range does not introduce false detection conditions in the target installation environment.

Q: What is the significance of the sensing distance difference between these models?

A: The PM-K45-P-C3 provides 0.236" (6mm) sensing distance compared to the PM-K44P-C3 at 0.197" (5mm). This 1mm extension allows detection of objects at greater distances, providing design flexibility for applications with variable object positioning or increased tolerance requirements.

Q: Are the response time specifications equivalent?

A: The PM-K44P-C3 specifies a single response time of 20µs. The PM-K45-P-C3 offers dual response time options at 20µs and 80µs. Applications requiring the faster 20µs response can operate identically to the original component. The 80µs option provides alternative timing for systems with different switching requirements.

Q: How do the output configurations differ between these models?

A: The PM-K44P-C3 features selectable Dark-ON/Light-ON output modes within a single PNP configuration. The PM-K45-P-C3 implements PNP output with open collector topology. Both configurations maintain PNP output compatibility for circuit integration. Verify that the specific output mode requirements of the application are satisfied by the substitute's open collector implementation.

Q: What are the packaging and mounting considerations?

A: Both models utilize module packaging with wire leads and chassis mount configuration. The PM-K44P-C3 specifies slot-type packaging, while the PM-K45-P-C3 provides standard module packaging. Mechanical fit verification is required if the original slot-type form factor is critical to the installation design.

Q: Are there any compliance or certification differences?

A: Both components maintain EAR99 ECCN and 8543.70.9860 HTSUS classifications. The PM-K45-P-C3 demonstrates ROHS3 compliance compared to RoHS compliance for the original component, reflecting current environmental standards. Moisture sensitivity levels remain identical at MSL 1 (Unlimited).
