SDP8014-301 Equivalent & Substitute Parts

Part Overview

The SDP8014-301 is a 935nm optical sensor manufactured by Honeywell Sensing and Productivity Solutions, classified as a photo detector with logic output and open collector configuration. The device features a radial 3-lead side view package and operates across the temperature range of -40°C to 85°C. This part is currently listed as obsolete, making identification of functionally equivalent substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the SDP8014-301 is determined by the following critical parameters: wavelength (935nm), sensor type (photo detector with logic output), output configuration (open collector), and operating temperature range (-40°C to 85°C). All substitute parts must maintain these core electrical specifications. Package configuration variations are permitted where mechanical integration allows, provided the lead count and functional pinout remain compatible. RoHS and REACH compliance status must be maintained or exceed the original specification.

The substitute parts are grouped into two primary categories based on package type: radial side-view configurations and 3-SIP side-view configurations. Within each category, parts are further differentiated by output type (open collector versus push-pull), though only open collector variants provide direct functional equivalence to the SDP8014-301.

Engineering Selection Recommendations

Primary Substitute: OPL550-OCA

The OPL550-OCA from TT Electronics / Optek Technology provides the closest functional match to the SDP8014-301. Both parts operate at 935nm wavelength, feature open collector output configuration, and maintain identical operating temperature specifications (-40°C to 85°C). The OPL550-OCA holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Inventory availability is substantial at 1,387 pieces.

Secondary Substitute: OPL551-OCA

The OPL551-OCA serves as an alternative where open collector inverter logic is acceptable within system design. This part maintains all critical electrical parameters including wavelength, temperature range, and compliance certifications. The inverter output characteristic must be evaluated against circuit requirements. Inventory availability is 970 pieces.

Package-Specific Alternative: OPL561-OC

For applications where 3-SIP package configuration is mechanically compatible, the OPL561-OC provides equivalent electrical performance with open collector inverter output. This part is actively manufactured with 702 pieces in stock.

All recommended substitutes maintain REACH unaffected status and MSL 1 (unlimited) moisture sensitivity rating, matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can OPL530 directly replace the SDP8014-301?

A: OPL530 operates at the same wavelength (935nm) and temperature range but features NPN output rather than open collector. Direct substitution requires circuit redesign to accommodate the different output configuration. This part is suitable only if system design permits NPN logic integration.

Q: What is the difference between OPL550-OCA and OPL551-OCA?

A: Both parts feature open collector output and identical electrical specifications. The primary distinction is the inverter characteristic of OPL551-OCA, which inverts the logic signal compared to OPL550-OCA. Selection depends on whether the application requires inverted or non-inverted logic output.

Q: Are package differences between radial and 3-SIP configurations significant?

A: Package configuration affects mechanical integration and PCB layout. Radial packages (OPL550-OCA, OPL551-OCA) differ from 3-SIP packages (OPL561-OC) in lead arrangement and mounting orientation. Verify mechanical compatibility with existing circuit board designs before substitution.

Q: Does the SDP8014-301 obsolescence affect substitute availability?

A: All recommended substitutes are active products from TT Electronics / Optek Technology with substantial inventory levels (702 to 4,804 pieces), ensuring reliable long-term supply. The Honeywell part's obsolete status does not impact substitute component availability.

Q: Are all substitutes RoHS and REACH compliant?

A: All recommended substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting or exceeding the original SDP8014-301 regulatory requirements.
