APDS-9103-L22 Equivalent & Substitute Parts

Part Overview

The APDS-9103-L22 is a reflective optical sensor manufactured by Broadcom Limited, designed for proximity detection applications requiring a 0.394" (10mm) sensing distance. This component features a phototransistor output configuration with through-hole radial packaging. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy product support, and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APDS-9103-L22 is determined by the following critical parameters:

• Sensing Method: Reflective optical detection capability
• Manufacturer: Broadcom Limited (same manufacturer ensures design compatibility)
• Output Type: Phototransistor or photodiode configuration
• Sensing Distance: Functional proximity range (0.394" / 10mm primary specification)
• Current Ratings: Collector current (Ic) and forward current (If) capacity
• Response Time: Signal detection speed in microseconds
• Operating Temperature Range: -25°C to 85°C minimum requirement
• Compliance: REACH Unaffected status

The HSDL-9100-021 qualifies as a manufacturer-recommended substitute based on shared reflective sensing methodology, identical manufacturer origin, and compatible electrical performance within the specified operating envelope.

Engineering Selection Recommendations

The HSDL-9100-021 is designated as the manufacturer-recommended substitute for the obsolete APDS-9103-L22. Selection of this alternative is supported by the following factors:

• Active Product Status: The HSDL-9100-021 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both components maintain REACH Unaffected status. The substitute achieves ROHS3 Compliant certification, exceeding the compliance profile of the original part.
• Electrical Performance: The substitute provides enhanced current capacity (100 mA vs. 20 mA collector current), supporting applications with higher power requirements.
• Temperature Range Extension: Operating temperature range extends to -40°C, providing broader environmental compatibility.
• Manufacturer Continuity: Both components originate from Broadcom Limited, ensuring design philosophy and quality standards alignment.

Substitution requires evaluation of mounting type transition (through-hole to surface mount) and sensing distance reduction (10mm to 5mm), which necessitate circuit board redesign and application-specific validation.

Frequently Asked Questions (FAQ)

Q: Why is the APDS-9103-L22 being discontinued? A: The APDS-9103-L22 is classified as obsolete. The HSDL-9100-021 represents Broadcom Limited's current-generation reflective optical sensor technology.

Q: What is the primary difference between these two sensors? A: The main differences are sensing distance (10mm vs. 5mm), output type (phototransistor vs. photodiode), mounting configuration (through-hole radial vs. surface mount 4-SMD), and current capacity (20 mA vs. 100 mA collector current).

Q: Can the HSDL-9100-021 be used as a direct pin-for-pin replacement? A: No. The HSDL-9100-021 uses surface mount 4-SMD packaging, while the APDS-9103-L22 uses through-hole radial packaging. Circuit board redesign is required.

Q: Does the reduced sensing distance (5mm vs. 10mm) affect application compatibility? A: Sensing distance reduction must be evaluated against specific application requirements. Proximity detection applications with object detection ranges exceeding 5mm require alternative solutions.

Q: Are both components RoHS compliant? A: The HSDL-9100-021 is ROHS3 Compliant. The APDS-9103-L22 RoHS status is not specified in available documentation.

Q: What is the response time difference? A: The APDS-9103-L22 has response times of 3µs and 4µs, while the HSDL-9100-021 has response times of 6µs. This difference may impact high-speed detection applications.

Q: Are both components REACH compliant? A: Both components maintain REACH Unaffected status, indicating compliance with REACH regulatory requirements.
