Dialight 5503008 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5503008 is a dual-color LED circuit board indicator featuring green and red light-emitting elements in a 5mm, T-1 3/4 through-hole right-angle configuration. This component is classified as obsolete, though 804 units remain in current inventory. The part delivers 40mcd green illumination at 565nm and 90mcd red illumination at 660nm with a 60° viewing angle and diffused lens design. Identification of active equivalent parts is necessary for new designs and long-term supply chain continuity, as the original part number transitions out of active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5503008 is determined by strict equivalence across the following critical parameters: color configuration (green and red), wavelength specifications (565nm and 660nm), forward voltage ratings (2.1V green, 1.8V red), forward current (20mA), millicandela output (40mcd green, 90mcd red), viewing angle (60°), lens type (diffused), physical size (5mm, T-1 3/4), and mounting configuration (through-hole, right-angle). All substitute parts must maintain identical electrical and mechanical characteristics to ensure direct functional replacement without circuit redesign or performance degradation.

The four active substitute parts—5503005F, 5503007010F, 5503008F, and 5503012F—meet these substitution criteria. These parts are manufactured by Dialight within the 550 series and carry active product status with RoHS3 compliance certification, providing improved supply availability and regulatory alignment compared to the obsolete 5503008.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts—5503005F, 5503007010F, 5503008F, and 5503012F—are functionally equivalent to the obsolete 5503008 based on electrical and mechanical parameter alignment. Selection among these active alternatives should prioritize RoHS3 compliance certification, which all substitutes provide. The 5503005F offers the highest current inventory level at 2048 units, supporting extended production runs and supply chain resilience. The 5503008F maintains the closest part number lineage to the original 5503008, though lens style and size specifications are not documented for this variant. The 5503007010F and 5503012F provide complete specification documentation with round domed-top lens configurations matching the original design intent.

For new designs and production transitions, any of these four parts may be selected without circuit modification, provided that bulk packaging accommodates manufacturing workflow requirements.

Frequently Asked Questions (FAQ)

Q: Can 5503005F, 5503007010F, 5503008F, and 5503012F be used interchangeably with 5503008?

A: Yes. All four substitute parts maintain identical electrical parameters (2.1V green, 1.8V red forward voltage; 20mA forward current; 40mcd green, 90mcd red output) and mechanical mounting configuration (5mm through-hole right-angle). Direct substitution requires no circuit redesign.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ in packaging format (all bulk versus original tape-and-reel), product status (all active versus obsolete), and documentation completeness. The 5503008F does not specify lens style or size, while 5503005F, 5503007010F, and 5503012F fully document round domed-top lens design.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All four substitute parts carry RoHS3 compliance certification, whereas the original 5503008 RoHS status is not specified.

Q: Which substitute part has the best supply availability?

A: The 5503005F maintains the highest inventory level at 2048 units in current stock.

Q: Does lens style affect substitution eligibility?

A: Lens style is a documented parameter for the original 5503008 (round with domed top). The 5503008F does not specify lens style or size; however, all other electrical and mechanical parameters remain equivalent. For applications requiring confirmed domed-top lens geometry, 5503005F, 5503007010F, or 5503012F are recommended.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: The original 5503008 and all substitutes share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). All substitutes provide RoHS3 compliance, which the original part does not specify.
