LED GREEN DIFFUSED T-1 3/4 T/H 4304H5-500 Equivalent & Substitute Parts

Part Overview

The 4304H5-500 is a green diffused LED indicator manufactured by Visual Communications Company (VCC) in the T-1 3/4 (5mm) through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The part functions as a discrete green LED indication element with a forward voltage of 2.1V and a brightness rating of 16 millicandela, suitable for standard indicator applications requiring through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 4304H5-500 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Forward voltage (Vf): 2.1V typical
• Test current: 10mA
• Millicandela rating: 16mcd
• Peak wavelength: 572nm

Mechanical Parameters:

• Lens size: 5mm, T-1 3/4
• Lens color and transparency: Green diffused
• Mounting type: Through hole radial
• Maximum height: 9.98mm

Compliance Parameters:

• RoHS3 compliance required
• ECCN: EAR99
• HTSUS: 8541.41.0000

The 4304H5 (bulk packaging variant) meets all substitution criteria as an active product within the same 4304H series, maintaining identical electrical and mechanical specifications while offering improved availability and compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 4304H5 is the direct active equivalent for the obsolete 4304H5-500. Both parts are manufactured by VCC within the same 4304H series and maintain identical electrical and mechanical specifications. The 4304H5 offers superior availability with 5,809 units in stock compared to 935 units of the obsolete variant.

From a compliance perspective, both parts are ROHS3 compliant and carry the same ECCN and HTSUS classifications. The 4304H5 provides an improved moisture sensitivity level (MSL 1 with unlimited shelf life) compared to the 4304H5-500 (MSL 2 with 1-year shelf life), resulting in better long-term storage characteristics and reduced risk of moisture-related degradation.

The packaging difference (bulk versus tape/reel) does not affect electrical or mechanical compatibility. Selection between these variants depends solely on procurement quantity requirements and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can the 4304H5 directly replace the 4304H5-500 in existing designs?

A: Yes. The 4304H5 is electrically and mechanically identical to the 4304H5-500. All critical parameters including forward voltage (2.1V), test current (10mA), brightness (16mcd), wavelength (572nm), lens size (5mm T-1 3/4), and mounting configuration (through-hole radial) are equivalent. Direct substitution requires no circuit modifications.

Q: What is the difference between the 4304H5-500 and 4304H5 part numbers?

A: The suffix "-500" in the 4304H5-500 designates tape/reel packaging, while the 4304H5 is supplied in bulk packaging. The electrical and mechanical specifications are identical. The packaging designation does not affect component performance or compatibility.

Q: Why is the 4304H5-500 classified as obsolete?

A: The 4304H5-500 is obsolete due to its packaging variant status. The active 4304H5 bulk variant remains in production and is the recommended procurement choice for new designs and ongoing production support.

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

A: Both parts are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The 4304H5 offers improved moisture sensitivity characteristics (MSL 1 unlimited shelf life versus MSL 2 one-year shelf life), providing better long-term storage reliability.

Q: What are the key parameters that determine substitution eligibility for this LED?

A: Substitution is determined by equivalence in forward voltage (2.1V), test current (10mA), brightness rating (16mcd), peak wavelength (572nm), lens size (5mm T-1 3/4), lens color and transparency (green diffused), mounting type (through-hole radial), and maximum height (9.98mm). All these parameters must match for direct substitution.

Q: Can this LED be used in applications requiring different brightness levels?

A: No. The 16mcd brightness rating is a fixed specification. Applications requiring different brightness levels require selection of alternative LED models with different millicandela ratings.
