Dialight 5510709 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5510709 is a 3mm yellow LED circuit board indicator designed for 5V applications with 10mA current rating. This component features a diffused, tinted lens with round domed top and is configured for through-hole, right-angle mounting on printed circuit boards. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from the same manufacturer series maintain identical electrical and mechanical specifications while offering current product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5510709 is determined by strict equivalence across the following critical parameters:

• Color: Yellow (585nm peak wavelength)
• Electrical specifications: 5V voltage rating, 10mA current, 12.6mcd brightness
• Optical characteristics: 60° viewing angle, diffused tinted lens
• Mechanical form factor: 3mm T-1 lens size, round domed top
• Mounting configuration: Through-hole, right-angle orientation
• Environmental compliance: MSL 1, REACH unaffected, EAR99 classification

All four substitute parts (5510701010F, 5510701F, 5510704F, 5510709F) meet these criteria and are direct functional equivalents. The primary distinction is product status: the main part 5510709 is obsolete, while all substitutes maintain active status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using Dialight 5510709, transition to an active substitute part is necessary due to obsolete product status. All four substitute parts provide identical electrical and optical performance with the following considerations:

Part 5510709F offers the highest current inventory (2289 units) and maintains the same base product number as the original, providing direct continuity in design documentation and procurement records.

Parts 5510701010F and 5510701F share base product number 5510701 with comparable inventory levels (1096 and 983 units respectively) and full ROHS3 compliance certification.

Part 5510704F, based on product number 5510704, provides an alternative with 925 units in stock and equivalent compliance status.

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can 5510709 be directly replaced with any of the substitute parts?

A: Yes. All four substitute parts (5510701010F, 5510701F, 5510704F, 5510709F) are direct functional equivalents with identical electrical ratings (5V, 10mA), optical output (12.6mcd, 585nm yellow), and mechanical form factor (3mm T-1 through-hole right-angle mount).

Q: What is the primary reason for substitution?

A: The original 5510709 is classified as obsolete. The substitute parts maintain active product status with current manufacturing support and improved availability.

Q: Are there packaging differences between the main part and substitutes?

A: The main part 5510709 is specified with "-" packaging notation. All substitute parts are supplied in bulk packaging, which is standard for active production components.

Q: Do all substitutes meet current compliance standards?

A: Yes. All four substitute parts carry ROHS3 compliance certification and REACH unaffected status. The original 5510709 does not specify RoHS status but shares identical environmental classification (MSL 1, EAR99, HTSUS 8541.41.0000).

Q: Which substitute offers the best availability?

A: Part 5510709F provides the highest inventory level at 2289 units in stock, along with the same base product number as the original part.

Q: Are there any electrical or optical performance differences?

A: No. All substitute parts maintain identical specifications: 5V voltage, 10mA current, 12.6mcd brightness, 585nm peak wavelength, 60° viewing angle, and diffused tinted lens characteristics.
