Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HOA1888-013 is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Sensing distance: 0.472" (12mm)
• Sensing method: Through-Beam
• Package type: Module, Slotted
• Operating temperature range: -40°C ~ 85°C
• Unamplified output type
• RoHS compliance status

Secondary Compatibility Criteria:

• Current ratings (DC Forward and Collector maximum values)
• Voltage breakdown specifications
• Response time characteristics
• Mounting configuration

The HOA1888-011 qualifies as a substitute part because it maintains identical sensing distance, through-beam sensing method, slotted module packaging, operating temperature range, and unamplified output type. Both components are manufactured by Honeywell and share the same RoHS compliance status. Differences in output configuration (phototransistor versus photodarlington), response time, voltage breakdown rating, and mounting type (snap-in versus surface mount) must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HOA1888-013 and HOA1888-011 are obsolete products from Honeywell Sensing and Productivity Solutions. Selection between these components must account for the following documented differences:

Output Configuration Difference: The HOA1888-013 features photodarlington output, while the HOA1888-011 provides phototransistor output. These output types exhibit different electrical characteristics and switching behavior. Photodarlington outputs provide higher current gain, whereas phototransistor outputs offer faster response times.

Response Time Difference: The HOA1888-011 demonstrates a response time of 15µs compared to the HOA1888-013's 75µs. This five-fold improvement in response time may be critical for applications requiring rapid optical detection cycles.

Voltage Breakdown Rating Difference: The HOA1888-011 supports a maximum collector-emitter breakdown voltage of 30V, compared to 15V for the HOA1888-013. This higher voltage rating provides additional design margin in circuits operating at elevated voltages.

Mounting Configuration Difference: The HOA1888-013 uses surface mount configuration, while the HOA1888-011 employs snap-in mounting. Physical installation requirements and PCB layout compatibility must be verified before substitution.

Both components maintain identical sensing distance, through-beam sensing method, slotted module packaging, operating temperature range, current ratings, and RoHS compliance status. Selection should be based on specific application requirements regarding output type, response time, voltage tolerance, and mechanical mounting constraints.

Frequently Asked Questions (FAQ)

Q: Can the HOA1888-011 directly replace the HOA1888-013 in all applications?

A: Direct replacement is not guaranteed without application-specific verification. While both components share identical sensing distance, through-beam method, and operating temperature range, they differ in output configuration (phototransistor versus photodarlington), response time (15µs versus 75µs), voltage breakdown rating (30V versus 15V), and mounting type (snap-in versus surface mount). Circuit design, signal processing requirements, and mechanical constraints must be evaluated.

Q: What is the primary functional difference between photodarlington and phototransistor outputs?

A: Photodarlington output provides higher current gain and sensitivity, making it suitable for applications requiring strong signal amplification. Phototransistor output offers faster response time and is appropriate for applications demanding rapid optical detection cycles. The HOA1888-011's 15µs response time is significantly faster than the HOA1888-013's 75µs response time.

Q: Are both parts RoHS compliant?

A: Yes, both the HOA1888-013 and HOA1888-011 are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What are the mounting compatibility considerations?

A: The HOA1888-013 is configured for surface mount installation, while the HOA1888-011 uses snap-in mounting. These mounting types require different mechanical interfaces and PCB layouts. Substitution requires verification that the target application's mechanical design accommodates the alternative mounting configuration.

Q: Do both parts operate across the same temperature range?

A: Yes, both components operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: What current ratings apply to both components?

A: Both the HOA1888-013 and HOA1888-011 share identical maximum current specifications: DC Forward current (If) of 50 mA and Collector current (Ic) of 30 mA. Circuit design must account for these current limitations regardless of which component is selected.
