Dialight 5501304 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5501304 is a 5mm through-hole LED circuit board indicator featuring a single green diffused lens with domed top. This component operates at 1.8V with 2mA current consumption and delivers 1.8 millicandela brightness at a 565nm peak wavelength. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Active alternatives from the Dialight 550 and 561 series provide direct functional equivalence with improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5501304 is determined by strict equivalence across the following parameters: color (green), wavelength peak (565nm), configuration (single), current rating (2mA), millicandela rating (1.8mcd), viewing angle (50°), lens type (diffused), lens style (round with domed top), lens size (5mm, T-1 3/4), voltage rating (1.8V), and mounting type (through hole).

All identified substitute parts meet these criteria without exception. The primary distinction between the main part and substitutes is product status: the 5501304 is obsolete, while all substitute parts maintain active status. Secondary differences include packaging format and RoHS compliance certification, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete Dialight 5501304, the 5501304F provides the most direct replacement path within the same 550 series while maintaining identical electrical and mechanical specifications. This part carries ROHS3 compliance certification and demonstrates superior inventory availability at 2313 units.

For new designs or applications requiring extended product lifecycle support, the Dialight 561 series substitutes (5611301050F, 5611301070F, 5611301080F, 5611301090F, 5611301100F) are all active products with ROHS3 compliance. The 5611301100F offers the highest inventory level at 4650 units, supporting volume production requirements.

All substitute parts maintain identical electrical performance, mechanical form factor, and environmental compliance status relative to the original 5501304 specification.

Frequently Asked Questions (FAQ)

Q: Can the 5501304F directly replace the 5501304 in existing designs?

A: Yes. The 5501304F is electrically and mechanically identical to the 5501304. The primary difference is product status (active versus obsolete) and packaging format (bulk). No circuit modifications are required.

Q: What is the difference between the 550 series (5501304F) and 561 series substitutes?

A: Both series deliver identical electrical and optical performance for this green LED indicator specification. The 561 series represents a newer product line with active status and higher inventory availability. Series selection does not affect circuit compatibility or performance.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry ROHS3 compliance certification. The original 5501304 does not specify RoHS status.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk versus other formats) affects only logistics and handling. Electrical and mechanical specifications remain identical across all substitute parts.

Q: Which substitute part should be selected for maximum inventory availability?

A: The 5611301100F provides the highest inventory level at 4650 units, supporting immediate procurement for volume applications.
