SD5410-003 Equivalent & Substitute Parts Reference

Part Overview

The SD5410-003 is a phototransistor optical sensor manufactured by Honeywell Sensing and Productivity Solutions, housed in a TO-46-3 metal can package with top view orientation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across an extended temperature range of -55°C to 125°C and features a 12° viewing angle with maximum collector current of 8 mA and 150 mW power dissipation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD5410-003 is determined by the following criteria:

Electrical Parameters: Substitute parts must maintain voltage breakdown rating of 30 V minimum, support collector current requirements, and operate within the specified dark current parameters. The maximum power dissipation of 150 mW establishes thermal design constraints.

Mechanical & Optical Parameters: Through-hole mounting type is required for direct PCB compatibility. Top view orientation is mandatory for optical axis alignment. Viewing angle variations are acceptable within application-specific tolerances.

Environmental & Compliance: Operating temperature range must encompass the -55°C to 125°C specification or be verified as compatible with the application's actual operating envelope. RoHS compliance status ensures regulatory alignment.

Package Considerations: While the original SD5410-003 uses TO-46-3 metal can packaging, substitute parts in alternative through-hole packages (TO-206AA, TO-18-3) are acceptable provided mechanical mounting and thermal characteristics are verified for the specific application.

The three identified substitute parts (MTD8600N4-T, OP830SL, VEMT2020X01) meet core electrical and optical sensor classification criteria but present distinct trade-offs in current capacity, temperature range, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

MTD8600N4-T (Marktech Optoelectronics): This substitute meets the 30 V voltage requirement and provides enhanced current capacity (50 mA vs. 8 mA). The TO-206AA/TO-18-3 metal can package maintains through-hole compatibility. However, the operating temperature range (-30°C to 100°C) does not extend to the -55°C lower limit of the original part. This substitute is suitable for applications operating within the -30°C to 100°C envelope. Active product status ensures long-term availability.

OP830SL (TT Electronics/Optek Technology): This substitute provides the widest operating temperature range (-65°C to 125°C), exceeding the original specification at the lower end. However, the voltage breakdown rating is limited to 15 V, which is below the 30 V specification of the SD5410-003. This voltage limitation restricts use to circuits designed for 15 V maximum operation. The TO-206AA/TO-18-3 metal can package maintains through-hole compatibility. Dark current is elevated at 1 µA. Active product status and ROHS3 compliance are confirmed.

VEMT2020X01 (Vishay Semiconductor Opto Division): This substitute features automotive-grade qualification (AEC-Q101) and active product status. However, it employs surface-mount packaging (2-SMD, Gull Wing) rather than through-hole, requiring PCB redesign for direct substitution. The operating temperature range (-40°C to 100°C) does not meet the -55°C lower limit. Maximum power dissipation is reduced to 100 mW. This option is applicable only when PCB layout modifications are feasible and operating temperature requirements are within -40°C to 100°C.

Primary Recommendation: For direct through-hole replacement with maintained voltage specifications, MTD8600N4-T is the preferred substitute, provided the application operates within -30°C to 100°C. For extended low-temperature operation, OP830SL accommodates -65°C operation but requires circuit verification for 15 V voltage rating compatibility.

Frequently Asked Questions (FAQ)

Q: Can MTD8600N4-T directly replace SD5410-003 in all applications?

A: MTD8600N4-T provides electrical and package compatibility for applications operating between -30°C and 100°C. Applications requiring operation below -30°C require alternative selection or thermal management verification.

Q: Why is OP830SL listed as a substitute if its voltage rating is only 15 V?

A: OP830SL is included as a substitute for circuit designs that operate at 15 V or below. The 15 V limitation restricts its use to lower-voltage applications. Circuits designed for the full 30 V capability of SD5410-003 cannot use OP830SL without redesign.

Q: Is VEMT2020X01 a viable substitute for through-hole PCB designs?

A: VEMT2020X01 requires surface-mount assembly and cannot be directly installed in through-hole footprints designed for SD5410-003. PCB redesign is necessary. Additionally, its operating temperature range (-40°C to 100°C) does not extend to -55°C.

Q: What are the key differences in current capacity between these parts?

A: SD5410-003 supports maximum collector current of 8 mA. All three substitutes (MTD8600N4-T, OP830SL, VEMT2020X01) support 50 mA maximum collector current. Applications designed for 8 mA operation are compatible with higher-capacity substitutes; however, circuit current-limiting design must be verified.

Q: Are all substitute parts RoHS compliant?

A: Yes. SD5410-003 is RoHS Compliant. MTD8600N4-T, OP830SL, and VEMT2020X01 are all ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the impact of viewing angle differences?

A: SD5410-003 specifies 12° viewing angle. MTD8600N4-T provides 24°, and VEMT2020X01 provides 30°. Wider viewing angles increase optical field of view. Applications with narrow optical requirements may require optical design verification when substituting with wider-angle parts.

Q: Can I use OP830SL in a -55°C environment?

A: OP830SL operates to -65°C, exceeding the -55°C requirement. However, the 15 V voltage rating must be verified as compatible with circuit design before selection.

Q: What inventory status should I consider for procurement?

A: SD5410-003 is obsolete (1055 pcs available). Active substitutes are: MTD8600N4-T (828 pcs), OP830SL (2889 pcs), and VEMT2020X01 (5540 pcs). Active product status ensures long-term availability for MTD8600N4-T, OP830SL, and VEMT2020X01.
