LTR-5576DH Equivalent & Substitute Parts

Part Overview

The LTR-5576DH is a phototransistor optical sensor manufactured by Lite-On Inc., designed for side view radial applications with through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The LTR-5576DH operates within a collector-emitter breakdown voltage of 30 V maximum and supports a maximum collector current of 1 mA, with dark current specifications of 100 nA maximum. Identifying compatible alternatives ensures design flexibility and supply chain reliability for applications requiring this sensor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTR-5576DH is determined by strict equivalence across the following critical parameters:

• Voltage - Collector Emitter Breakdown (Max): 30 V
• Current - Collector (Ic) (Max): 1 mA
• Current - Dark (Id) (Max): 100 nA
• Power - Max: 100 mW
• Mounting Type: Through Hole
• Orientation: Side View
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: Radial, 3 Lead, Side View

The LTR-5576D qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction is product status: LTR-5576D is active and available, whereas LTR-5576DH is obsolete. Both components share identical electrical ratings, thermal operating range, and physical packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The LTR-5576D is the direct equivalent for the obsolete LTR-5576DH. Selection of LTR-5576D is supported by:

• Complete electrical parameter equivalence across all specified ratings
• Identical mechanical packaging and mounting configuration
• Active product status ensuring ongoing availability and supply chain support
• ROHS3 compliance certification for the substitute part
• Equivalent moisture sensitivity classification (MSL 1)
• Shared manufacturer (Lite-On Inc.) ensuring consistent design and performance characteristics

No design modifications are required when transitioning from LTR-5576DH to LTR-5576D. Both components are pin-compatible and functionally interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can LTR-5576D directly replace LTR-5576DH in existing designs?

A: Yes. The LTR-5576D is a direct replacement. All electrical ratings, thermal specifications, and physical packaging are identical. No circuit modifications or PCB redesign is necessary.

Q: What is the primary reason for substitution?

A: The LTR-5576DH is obsolete. The LTR-5576D is the active equivalent from the same manufacturer, providing continuity for new production and ongoing support.

Q: Are there any compliance differences between the two parts?

A: The LTR-5576D carries ROHS3 compliance certification. Both parts maintain equivalent moisture sensitivity levels and REACH status.

Q: What are the critical parameters that define substitution eligibility?

A: Voltage rating (30 V), collector current (1 mA maximum), dark current (100 nA maximum), power dissipation (100 mW), through-hole mounting, side view orientation, operating temperature range (-40°C to 85°C), and radial 3-lead package configuration.

Q: Is packaging different between LTR-5576DH and LTR-5576D?

A: Both use identical radial, 3-lead, side view packaging. The LTR-5576D is supplied in bag packaging, while the LTR-5576DH packaging type was not specified. This does not affect functional compatibility or PCB mounting.
