Equivalent & Substitute Parts for Dialight 5219216

Part Overview

The Dialight 5219216 is a red diffused 3mm through-hole LED designed for indication applications, featuring a 2V forward voltage and 10mcd brightness rating. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The 521 series LED provides standard red indication with a 60° viewing angle and radial mounting configuration suitable for PCB assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5219216 is determined by the following critical parameters: red lens color, diffused lens transparency, 3mm form factor, through-hole radial mounting, and peak wavelength in the 635nm range. Forward voltage tolerance of 1.9V to 2V and viewing angle of 55° to 60° are acceptable for functional equivalence in indication circuits. Current rating variations (10mA to 20mA test current) and brightness differences (8.6mcd to 30mcd) do not prevent substitution but affect circuit design considerations. All substitute parts maintain the same package classification and mounting methodology.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5219216F is the primary direct substitute, maintaining identical electrical specifications (2V forward voltage, 3mm form factor, 60° viewing angle) while offering active product status and ROHS3 compliance. This part is recommended for applications requiring exact parameter matching with modern regulatory compliance.

The SSL-LX3044ID from Lumex provides the highest brightness rating (30mcd) and lowest profile (4.60mm height), suitable for applications requiring enhanced visibility or space-constrained PCB layouts. Forward voltage and viewing angle remain compatible with the original design.

The HLMP-1301-G0002 from Broadcom operates at 1.9V forward voltage, reducing power consumption by approximately 5% compared to the original 2V specification. This part is suitable for battery-powered or low-power indication circuits where voltage tolerance exists.

The 4303F1 from Visual Communications Company operates at 650nm peak wavelength with 16mcd brightness and 55° viewing angle, introducing minor spectral and optical differences. This part is suitable only when application requirements permit wavelength variation and reduced viewing angle.

All substitute parts maintain RoHS3 compliance, addressing regulatory requirements absent in the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5219216F directly replace the 5219216 without circuit modification?

A: Yes. The 5219216F maintains identical forward voltage (2V), lens size (3mm), viewing angle (60°), and radial mounting configuration. The primary difference is reduced test current (10mA vs 20mA) and slightly lower brightness (8.7mcd vs 10mcd), which do not require circuit redesign for standard indication applications.

Q: What are the height considerations when selecting a substitute?

A: The original 5219216 specifies 6.00mm maximum height. The SSL-LX3044ID offers 4.60mm height, providing 1.4mm clearance advantage for compact assemblies. The 4303F1 and HLMP-1301-G0002 exceed original height at 6.40mm and 6.35mm respectively, requiring PCB layout verification.

Q: Are all substitutes RoHS3 compliant?

A: All active substitute parts (5219216F, 4303F1, HLMP-1301-G0002, SSL-LX3044ID) are ROHS3 compliant. The original 5219216 is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulations.

Q: Which substitute offers the lowest power consumption?

A: The HLMP-1301-G0002 operates at 1.9V forward voltage with 10mA test current, providing approximately 5% lower voltage drop compared to the original 2V specification. The 5219216F and SSL-LX3044ID also operate at 10mA test current, reducing power consumption relative to the original 20mA specification.

Q: What packaging options are available for production quantities?

A: The 5219216F, 4303F1, and SSL-LX3044ID are available in bulk packaging suitable for high-volume assembly. The HLMP-1301-G0002 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place equipment.

Q: Can the SSL-LX3044ID be used in applications requiring exact brightness matching?

A: No. The SSL-LX3044ID provides 30mcd brightness, significantly exceeding the original 10mcd specification. This part is suitable only for applications where increased brightness is acceptable or beneficial. For brightness-critical applications, the 5219216F (8.7mcd) or HLMP-1301-G0002 (8.6mcd) provide closer matching.
