5SRDL-F LED Red Diffused T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The 5SRDL-F is a red diffused LED indicator manufactured by Bivar Inc., designed for through-hole mounting applications. This component operates at 1.7V forward voltage with a 6mcd luminous intensity and features a 5mm T-1 3/4 radial package. The product is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5SRDL-F is based on strict alignment of the following critical parameters:

Physical Compatibility Requirements:

• Package type must be radial through-hole configuration
• Lens size must be 5mm T-1 3/4 form factor
• Mounting method must support through-hole PCB assembly

Electrical Compatibility Requirements:

• Forward voltage (Vf) must be 1.7V or within acceptable circuit tolerance
• Luminous intensity (6mcd) establishes the brightness class
• Peak wavelength (645nm) confirms red color specification
• Test current (2mA) defines the operating point

Optical Compatibility Requirements:

• Lens transparency must be diffused
• Viewing angle of 40° must be maintained or exceeded
• Color must be red

The HLMP-D150 manufactured by onsemi qualifies as a substitute based on matching these core parameters within the allowed electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: Both the 5SRDL-F and HLMP-D150 share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export control and tariff treatment. Both components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Product Status Consideration: Both components are classified as obsolete. When selecting between obsolete parts, priority should be given to inventory availability and supply chain continuity. The HLMP-D150 currently has 15,436 units in stock compared to 940 units of the 5SRDL-F, providing greater supply security for ongoing production requirements.

Substitution Basis: The HLMP-D150 is listed as a substitute for the 5SRDL-F based on functional equivalence within the red LED indicator category. Selection of this substitute is appropriate for applications requiring through-hole red LED indication with diffused lens characteristics and 645nm peak wavelength operation.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-D150 be used as a direct replacement for the 5SRDL-F in existing PCB designs?

A: The HLMP-D150 is designated as a substitute part. Direct compatibility depends on matching physical package dimensions (5mm T-1 3/4 radial), electrical parameters (1.7V forward voltage, 2mA test current), and optical characteristics (diffused lens, 645nm wavelength, 40° viewing angle). Verification against the onsemi HLMP-D150 datasheet is required to confirm all parameters align with the original 5SRDL-F specification.

Q: What are the critical parameters that determine if a substitute LED is compatible?

A: Substitution compatibility is determined by: (1) Physical form factor - 5mm T-1 3/4 radial through-hole package; (2) Electrical operation - 1.7V forward voltage at 2mA test current; (3) Optical characteristics - red color (645nm peak wavelength), diffused lens, 40° viewing angle; (4) Luminous intensity - 6mcd at test current.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both the 5SRDL-F and HLMP-D150 share identical ECCN (EAR99), HTSUS code (8541.41.0000), and MSL rating (1 - Unlimited), indicating equivalent regulatory treatment and handling requirements.

Q: Why is the HLMP-D150 recommended despite both parts being obsolete?

A: The HLMP-D150 is recommended based on current inventory availability (15,436 units in stock) compared to the 5SRDL-F (940 units), providing superior supply chain continuity for production and maintenance applications.

Q: What should be verified before implementing the HLMP-D150 as a substitute?

A: Confirm the following parameters from the onsemi HLMP-D150 datasheet: lens size (5mm T-1 3/4), mounting configuration (through-hole radial), forward voltage (1.7V typical), test current (2mA), luminous intensity (6mcd), lens transparency (diffused), peak wavelength (645nm), and viewing angle (40°).
