SD5610-001 Equivalent & Substitute Parts

Part Overview

The SD5610-001 is an optical sensor manufactured by Honeywell Sensing and Productivity Solutions, designed as a 935nm photo detector with logic output in a TO-46-3 Lens Top Metal Can package. This component functions as an optoschmitt detector with open collector output configuration. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, redesign, and procurement planning. Substitute parts must maintain functional equivalence in wavelength, output type, and electrical performance while accommodating package form factor differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD5610-001 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Wavelength: 935nm (infrared detection band)
• Output Type: Open Collector logic output
• Type Classification: Photo Detector with Logic Output
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Acceptable Variation Parameters:

• Package / Case: Substitutes in TO-18 small package are acceptable where circuit board layout permits, as both TO-46-3 and TO-18 are hermetic metal can packages with compatible pinout configurations for this sensor class
• Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges (-55°C ~ 110°C or -40°C ~ 100°C) are functionally compatible

Non-Substitutable Parameters:

• Wavelength deviation from 935nm
• Output type changes (Open Collector to other types)
• Moisture Sensitivity Level changes

All three substitute parts (OPL800-OC, OPL801-OC, OPL820-OC) meet these critical matching criteria. OPL801-OC contains an inverter function and requires logic inversion consideration in circuit design.

Parameter Comparison

Engineering Selection Recommendations

OPL800-OC Selection Criteria: OPL800-OC is a direct functional equivalent with non-inverted open collector output. This part maintains identical logic output behavior to the SD5610-001 without requiring circuit modifications. Extended operating temperature range (-55°C ~ 110°C) provides broader environmental coverage. Active product status ensures long-term availability. ROHS3 compliance exceeds the original RoHS requirement. Package transition from TO-46-3 to TO-18 requires PCB layout verification but maintains hermetic metal can construction.

OPL801-OC Selection Criteria: OPL801-OC provides equivalent wavelength and package specifications with inverter output logic. This part requires circuit-level logic inversion accommodation in the receiving circuit. Selection is appropriate only when logic inversion is functionally acceptable or when existing circuit design already incorporates inversion logic. Extended temperature range and active status match OPL800-OC advantages.

OPL820-OC Selection Criteria: OPL820-OC provides non-inverted open collector output with operating temperature range identical to the SD5610-001 (-40°C ~ 100°C). This part offers the closest thermal specification match. Active product status and ROHS3 compliance support long-term deployment. Package transition to TO-18 requires identical PCB layout considerations as OPL800-OC.

All three substitutes carry active product status, ensuring procurement viability and technical support availability. All meet current RoHS3 compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can OPL801-OC be used as a direct replacement for SD5610-001 without circuit modifications?

A: No. OPL801-OC contains an inverter function that inverts the logic output compared to SD5610-001. Direct substitution requires circuit-level logic inversion accommodation. OPL800-OC or OPL820-OC are direct functional replacements without logic inversion requirements.

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

A: Both parts provide identical non-inverted open collector output at 935nm wavelength. The primary difference is operating temperature range: OPL800-OC operates -55°C ~ 110°C, while OPL820-OC operates -40°C ~ 100°C. OPL820-OC matches the original SD5610-001 temperature specification exactly.

Q: Is package transition from TO-46-3 to TO-18 acceptable?

A: Package transition is acceptable from an electrical and functional standpoint. Both are hermetic metal can packages with compatible sensor configurations. PCB layout verification is required to confirm mechanical fit, lead spacing, and optical window alignment in the application circuit board.

Q: Are all substitute parts RoHS compliant?

A: Yes. SD5610-001 is RoHS Compliant. All three substitute parts (OPL800-OC, OPL801-OC, OPL820-OC) are ROHS3 Compliant, which represents an enhanced compliance standard.

Q: Why is SD5610-001 classified as obsolete?

A: Product status reflects manufacturer discontinuation. Substitute parts from TT Electronics / Optek Technology Photologic® series provide equivalent functionality with active product status, ensuring continued availability and technical support.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These components do not require special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Can these optical sensors be used interchangeably in all applications?

A: Functional interchangeability is determined by wavelength (935nm), output type (Open Collector), and logic polarity requirements. OPL801-OC requires logic inversion accommodation. Package transition requires mechanical verification. All parts maintain identical MSL and RoHS compliance.
