LED RED DIFFUSED T-1 3/4 T/H 4304H1NF Equivalent & Substitute Parts

Part Overview

The 4304H1NF is a red diffused LED indicator manufactured by Visual Communications Company (VCC) in the 4304H series. This through-hole component features a 5mm T-1 3/4 lens form factor with a 2V forward voltage and 10mcd brightness rating, designed for discrete red LED indication applications. The 4304H1NF is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 4304H1NF is determined by strict equivalence across the following critical parameters:

Optical Characteristics: Lens color (red), lens transparency (diffused), lens size (5mm T-1 3/4), and lens style (round with domed top) must remain identical to preserve visual appearance and light distribution in the application.

Electrical Characteristics: Forward voltage (2V typical), test current (10mA), millicandela rating (10mcd), viewing angle (40°), and peak wavelength (630nm) must match to ensure circuit compatibility and performance equivalence.

Mechanical Characteristics: Mounting type (through hole), package form (radial), and maximum height (9.98mm) must be identical to ensure PCB compatibility and assembly process alignment.

Compliance & Certification: RoHS3 compliance status must be maintained for regulatory adherence.

The 4304H1 qualifies as a direct substitute based on complete parameter alignment across all optical, electrical, mechanical, and compliance criteria.

Parameter Comparison

Engineering Selection Recommendations

The 4304H1 is the direct active equivalent for the obsolete 4304H1NF. All optical, electrical, mechanical, and compliance parameters are identical. The 4304H1 maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original design.

The 4304H1 offers an additional advantage in moisture sensitivity level (MSL 1 with unlimited shelf life versus MSL 2 with 1-year shelf life), providing improved storage stability and extended component shelf life without performance degradation.

Inventory availability of the 4304H1 (8826 pcs in stock) ensures supply continuity for both new production and field replacement applications. Direct substitution requires no circuit modifications, PCB layout changes, or assembly process adjustments.

Frequently Asked Questions (FAQ)

Q: Can the 4304H1 be used as a direct replacement for the 4304H1NF in existing designs?

A: Yes. The 4304H1 is a direct equivalent with identical optical, electrical, and mechanical specifications. No circuit modifications or PCB layout changes are required. The component can be substituted on a one-to-one basis.

Q: What is the difference between the 4304H1NF and 4304H1?

A: The primary difference is product status: 4304H1NF is obsolete while 4304H1 is active. Additionally, the 4304H1 has improved moisture sensitivity level (MSL 1 with unlimited shelf life) compared to the 4304H1NF (MSL 2 with 1-year shelf life). All other specifications are identical.

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

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications. Regulatory requirements are fully satisfied by the 4304H1 substitute.

Q: What is the packaging difference between the 4304H1NF and 4304H1?

A: The 4304H1NF packaging designation is not specified in the data. The 4304H1 is supplied in bulk packaging. Both parts use identical radial through-hole package form factors with T-1 3/4 (5mm) supplier device packaging.

Q: Will the 4304H1 fit the same PCB footprint as the 4304H1NF?

A: Yes. Both parts have identical mechanical specifications including 9.98mm maximum height, radial package configuration, and through-hole mounting type. PCB footprints and assembly processes remain unchanged.

Q: Is the 4304H1 suitable for long-term storage?

A: Yes. The 4304H1 has MSL 1 rating with unlimited shelf life, providing superior storage stability compared to the 4304H1NF. This allows extended inventory holding without moisture-related performance degradation.
