Substitute Part Grouping Explanation

The HTB18L-N3A5AB qualifies as a substitute for the HTF18L-N2B5AA based on the following critical parameters that define functional equivalence:

Matching Parameters:

• Manufacturer: SICK, Inc. (same manufacturer ensures design compatibility)
• Category: Optical Sensors (identical sensor class)
• Output Configuration: NPN (identical electrical output type)
• Light Source: Red Laser Diode (655nm) (identical detection wavelength)
• Connection Method: Connector, M8 (identical physical interface)
• Ingress Protection: IP67 (identical environmental sealing)
• Voltage - Supply: 10V ~ 30V (identical power supply range)
• Operating Temperature: -30°C ~ 55°C (TA) (identical thermal operating range)
• Series: SureSense (same product family)

Allowable Variation:

• Sensing Distance: HTB18L-N3A5AB provides 1.181" ~ 11.811" (30mm ~ 300mm), which encompasses the original 1.575" ~ 11.811" (40mm ~ 300mm) range with extended minimum detection capability

The HTB18L-N3A5AB is classified as Active product status, ensuring ongoing availability and support compared to the obsolete HTF18L-N2B5AA.

Parameter Comparison

Engineering Selection Recommendations

The HTB18L-N3A5AB is the designated substitute for the obsolete HTF18L-N2B5AA. Selection of this substitute is supported by:

• Product Status: The HTB18L-N3A5AB maintains Active status, ensuring continued manufacturing support, availability, and technical documentation from SICK, Inc.
• Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. The HTB18L-N3A5AB carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.
• Functional Equivalence: All critical electrical and mechanical parameters align, with the substitute providing extended minimum sensing distance capability (30mm versus 40mm), which represents an enhancement rather than a limitation.
• Interface Compatibility: M8 connector interface and identical voltage supply range ensure direct integration into existing system designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the HTB18L-N3A5AB directly replace the HTF18L-N2B5AA in existing installations?

A: Yes. Both sensors share identical output configuration (NPN), power supply requirements (10V ~ 30V), M8 connector interface, and operating temperature range (-30°C ~ 55°C). The substitute provides equivalent functionality with extended sensing range capability.

Q: What is the difference in sensing distance between these two models?

A: The HTF18L-N2B5AA operates at 40mm to 300mm sensing distance, while the HTB18L-N3A5AB operates at 30mm to 300mm. The substitute extends the minimum detection range by 10mm, providing greater flexibility for close-proximity applications.

Q: Are there packaging differences between these components?

A: The HTF18L-N2B5AA packaging is not specified in available documentation. The HTB18L-N3A5AB is supplied in Bulk packaging. Both utilize identical M8 connector interface for field installation.

Q: Does the HTB18L-N3A5AB include adjustment capability?

A: Yes. The HTB18L-N3A5AB features adjustable potentiometer-based sensing distance calibration, allowing field optimization for specific application requirements. This adjustment capability is not documented for the original HTF18L-N2B5AA.

Q: What compliance certifications apply to the substitute part?

A: The HTB18L-N3A5AB carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory standards. Both components share identical ECCN and HTSUS classifications for export and tariff purposes.
