Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for optical sensors focuses strictly on matching the following key parameters: sensing method (Through-Beam), mounting type (Chassis Mount), package/case, output configuration, sensing distance, response time, operating temperature range, RoHS and MSL compliance, ECCN, and HTSUS codes. Only parts with fully-defined values for these parameters are considered for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Substitution of PM-T44 can be considered with PM-T45 primarily based on part status and compliance. PM-T44 is classified as obsolete, whereas PM-T45 is active. Both parts are RoHS compliant with an MSL rating of 1 (Unlimited), and both conform to ECCN EAR99 and HTSUS 8543.70.9860. Only products with matching compliance and certifications should be selected in regulated applications.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for substituting optical sensors in this product category? A: Sensing method, mounting type, package/case, output configuration, sensing distance, response time, operating temperature, RoHS and MSL compliance, ECCN, and HTSUS must all be matched.

Q2: Is PM-T45 compatible with chassis mount installations originally designed for PM-T44? A: Both PM-T44 and PM-T45 specify chassis mount as the mounting type. Package format for both parts is “Module, Wire Leads,” ensuring compatibility in chassis mount configurations.

Q3: Does the difference in sensing distance affect substitute selection? A: Sensing distance is a defined electrical parameter; PM-T44 is rated for 0.197" (5mm) and PM-T45 for 0.236" (6mm). Selection must account for the provided values.

Q4: Are the output configurations between PM-T44 and PM-T45 interchangeable? A: PM-T44 features NPN - Dark-ON/Light-ON - Selectable output configuration, while PM-T45 provides NPN - Open Collector output. Only listed output configurations should be considered for interchangeability.

Q5: What compliance certificates should be referenced when selecting a substitute optical sensor? A: RoHS (and ROHS3 where specified), Moisture Sensitivity Level (MSL), ECCN EAR99, and HTSUS 8543.70.9860 are referenced for substitute product selection.
