Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HOA0901-012 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Sensing method: Through-Beam architecture
• Output configuration: NPN open collector topology
• Mounting type: Through hole PCB mount
• Package form factor: PCB mount physical compatibility
• Sensing distance: Nominal 3.2mm range (±0.1mm tolerance acceptable)

Secondary Compatibility Criteria:

• Voltage supply range: Minimum 4.5V support required
• Current consumption: ≤7.5 mA acceptable
• Response time: ≤100ns acceptable
• Operating temperature: Minimum -40°C to 70°C coverage
• RoHS compliance status

The OPB471L11 manufactured by TT Electronics / Optek Technology satisfies all primary and secondary compatibility criteria, with sensing distance of 0.125" (3.18mm), which falls within acceptable tolerance of the original 3.2mm specification.

OPB471L11 Substitution Assessment:

The OPB471L11 is classified as an active product with current manufacturing status, providing supply chain continuity for applications previously utilizing the obsolete HOA0901-012. This substitute demonstrates full parameter compatibility across all critical electrical and mechanical specifications.

The OPB471L11 offers enhanced performance characteristics including faster response time (50ns versus 100ns) and extended operating temperature range (-40°C to 85°C versus -40°C to 70°C). The wider voltage supply range (4.5V to 16V) provides additional design flexibility compared to the original 4.5V to 5.5V specification.

Both components maintain identical RoHS compliance status and MSL ratings, supporting equivalent environmental and reliability requirements. The through-hole PCB mount form factor and NPN open collector output configuration ensure direct functional equivalence in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the OPB471L11 directly replace the HOA0901-012 in existing PCB designs?

A: Yes. The OPB471L11 maintains identical mounting type (through hole), package form factor (PCB mount), output configuration (NPN open collector), and sensing distance specification (3.18mm versus 3.2mm). No PCB layout modifications are required.

Q: What is the sensing distance tolerance between these components?

A: The HOA0901-012 specifies 0.126" (3.2mm) and the OPB471L11 specifies 0.125" (3.18mm). The difference of 0.02mm falls within standard optical sensor manufacturing tolerances and does not impact functional compatibility in through-beam applications.

Q: Are there voltage supply compatibility concerns?

A: No. The HOA0901-012 operates at 4.5V to 5.5V, while the OPB471L11 operates at 4.5V to 16V. Existing power supply designs for the original component will operate within the substitute's voltage range without modification.

Q: Does the OPB471L11 meet the same compliance requirements?

A: Yes. Both components are RoHS compliant and carry MSL rating 1 (Unlimited). The OPB471L11 holds ROHS3 certification, which represents current compliance standards.

Q: What is the current consumption difference?

A: The HOA0901-012 draws 7 mA while the OPB471L11 draws 7.5 mA. This 0.5 mA difference is negligible in most circuit designs and does not require power supply recalculation.

Q: Is the faster response time of the OPB471L11 a concern?

A: No. The OPB471L11 response time of 50ns is faster than the original 100ns specification. Faster response times do not create compatibility issues in applications designed for the original component.
