Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD5620-002 are qualified based on the following critical parameters:

Wavelength Matching: All substitute parts operate at 935nm, identical to the main part, ensuring compatibility with existing optical system designs and infrared transmission characteristics.

Output Configuration: All substitutes feature open collector logic output, maintaining electrical interface compatibility with existing circuit designs.

Functional Classification: All substitutes are classified as photo detectors with logic output, preserving the functional role within optical sensing applications.

Temperature Operating Range: Substitute parts must support the operating temperature envelope of the main part. The OPL820-OC matches the exact range (-40°C ~ 100°C), while OPL800-OC and OPL801-OC provide extended range capability (-55°C ~ 110°C), which is compatible for applications within the original specification.

Compliance Standards: All substitutes maintain RoHS3 compliance and MSL Level 1 rating, meeting regulatory and environmental requirements equivalent to the main part.

Package Consideration: Substitute parts utilize TO-18 small packages, which differ from the TO-46-3 lens top metal can of the main part. This represents a mechanical form factor change requiring PCB layout and mechanical mounting evaluation.

Parameter Comparison

Engineering Selection Recommendations

OPL820-OC is the primary substitute for direct replacement applications. This part maintains identical operating temperature range (-40°C ~ 100°C) and open collector output configuration. The TO-18 small package requires mechanical redesign but provides active product status with ROHS3 compliance and unlimited MSL rating. This substitute is suitable for applications where the original temperature specification is a design constraint.

OPL800-OC serves as an alternative substitute with extended temperature capability (-55°C ~ 110°C). The expanded operating range accommodates applications requiring operation beyond the original SD5620-002 specification. This part maintains open collector output and active product status. The TO-18 small package requires mechanical evaluation identical to OPL820-OC.

OPL801-OC is functionally equivalent to OPL800-OC with one critical distinction: the output is configured as open collector inverter rather than standard open collector. This inverted logic output creates a functional difference requiring circuit-level evaluation. Selection of OPL801-OC is appropriate only when inverted logic output is required by the application design.

All three substitutes are active products with current manufacturing support, ROHS3 compliance, and unlimited MSL ratings, providing supply chain continuity for the obsolete SD5620-002.

Frequently Asked Questions (FAQ)

Q: Can OPL800-OC, OPL801-OC, and OPL820-OC be used interchangeably with SD5620-002?

A: OPL800-OC and OPL820-OC are functionally interchangeable from an electrical standpoint, both featuring 935nm wavelength, open collector output, and identical MSL/RoHS compliance. OPL801-OC differs due to its inverted logic output configuration. All three require mechanical redesign due to package form factor change from TO-46-3 to TO-18 small.

Q: What is the primary difference between OPL820-OC and OPL800-OC?

A: The operating temperature range differs. OPL820-OC matches the SD5620-002 specification (-40°C ~ 100°C), while OPL800-OC provides extended range (-55°C ~ 110°C). Both maintain identical wavelength, output type, and compliance ratings.

Q: Why does OPL801-OC have different output characteristics?

A: OPL801-OC features open collector inverter output, which inverts the logic state compared to standard open collector configuration. This functional difference requires circuit evaluation to determine compatibility with existing designs.

Q: Are package changes significant for substitution?

A: Yes. The TO-46-3 lens top metal can differs mechanically from the TO-18 small package used by all substitutes. PCB layout, mounting hardware, and optical alignment require evaluation during implementation.

Q: Do all substitutes meet the same compliance requirements as SD5620-002?

A: All substitutes maintain RoHS3 compliance and MSL Level 1 (Unlimited) rating, meeting or exceeding the original part's compliance profile. All are active products with current manufacturing support.

Q: Which substitute should be selected for new designs?

A: OPL820-OC is recommended for designs requiring temperature range matching the original specification. OPL800-OC is suitable when extended temperature capability provides design margin. OPL801-OC is selected only when inverted logic output is required by circuit design.
