LW500AM LED White Clear 5MM T/H Equivalent & Substitute Parts

Part Overview

The LW500AM is a white LED indication component manufactured by Seoul Semiconductor Inc., designed for through-hole mounting applications. This discrete 3.3V radial LED features a 5mm clear lens with 850mcd brightness rating and is commonly used in indicator circuits requiring standard white light output.

The LW500AM is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this part is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LW500AM is determined by the following critical parameters:

• Lens Size and Style: Both parts must feature a 5.00mm diameter round lens with flat top configuration to ensure mechanical fit in existing PCB layouts and housings.
• Color and Lens Transparency: White color with clear lens transparency is required to maintain optical performance and visual consistency.
• Mounting Type: Through-hole radial configuration is mandatory for compatibility with existing circuit board designs.
• Electrical Parameters: Forward voltage (Vf), test current, and viewing angle must be within acceptable operating ranges for the application circuit.
• Regulatory Compliance: REACH and ECCN classifications must align with the original part to ensure compliance with applicable regulations.

The VAOL-5701WY4 from Visual Communications Company (VCC) meets these substitution criteria. While it exhibits a slightly higher forward voltage (4.6V vs. 3.3V) and increased brightness (1800mcd vs. 850mcd), these parameters remain within acceptable tolerance ranges for standard LED indication applications. The mechanical form factor, lens configuration, and mounting type are identical.

Engineering Selection Recommendations

The VAOL-5701WY4 is the identified substitute for the obsolete LW500AM. Selection of this substitute is supported by the following factors:

• Product Status: The VAOL-5701WY4 maintains active product status, ensuring ongoing availability and supply chain continuity.
• Regulatory Compliance: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance with export and environmental regulations.
• Mechanical Compatibility: Identical lens size, style, and through-hole radial mounting configuration ensure direct PCB layout compatibility without design modification.
• Electrical Compatibility: The 0.2V increase in forward voltage (3.3V to 4.6V) and increased brightness (850mcd to 1800mcd) are typical variations within LED indication circuit design tolerances.
• Inventory Availability: The VAOL-5701WY4 is available in high volume (19,400 pcs), supporting both immediate and long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can the VAOL-5701WY4 be used as a direct replacement for the LW500AM without circuit modification?

A: The VAOL-5701WY4 is mechanically and functionally compatible with the LW500AM for standard LED indication applications. The forward voltage difference of 0.2V and increased brightness are within typical operating tolerances for indicator circuits. Circuit validation is recommended for applications with strict voltage or brightness specifications.

Q: What is the height difference between these parts, and does it affect PCB assembly?

A: The VAOL-5701WY4 has a maximum height of 7.05mm compared to the LW500AM at 6.50mm, a difference of 0.55mm. This minimal height variation does not typically affect PCB assembly or housing clearance in standard LED indicator applications. Verify clearance in applications with height-constrained enclosures.

Q: Are there any differences in moisture sensitivity or storage requirements?

A: The LW500AM has MSL 1 (Unlimited), while the VAOL-5701WY4 has MSL 2 (1 Year). This indicates the substitute part requires controlled storage conditions within one year of manufacture. Standard component storage practices will accommodate this requirement.

Q: Why does the VAOL-5701WY4 have higher brightness than the LW500AM?

A: The VAOL-5701WY4 is rated at 1800mcd compared to the LW500AM at 850mcd. This increased brightness is a characteristic of the substitute part design and does not prevent substitution in standard indication applications. Applications requiring specific brightness levels should evaluate this parameter against circuit requirements.

Q: What is the base product number for the VAOL-5701WY4?

A: The base product number is VAOL-5701. The VAOL-5701WY4 is a specific variant within this product family.
