Dialight 5530123 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530123 is a dual-level LED circuit board indicator featuring integrated green and yellow LEDs in a 3mm T-1 through-hole right-angle configuration. This component is classified as obsolete, though 881 units remain in current inventory. The part delivers 16mcd green and 6.3mcd yellow output at 10mA operating current with a 2.1V forward voltage rating. Due to its obsolete status, identifying active equivalent parts ensures design continuity and supply chain reliability for applications requiring this specific LED indicator configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530123 is determined by strict equivalence across the following critical parameters:

• Dual LED Configuration: 2 High arrangement with green and yellow LEDs
• Color and Wavelength: Green at 563nm and yellow at 585nm
• Optical Characteristics: Diffused, tinted lens with round domed top
• Electrical Ratings: 10mA current, 2.1V forward voltage
• Brightness Output: 16mcd green and 6.3mcd yellow
• Physical Form Factor: 3mm T-1 through-hole right-angle mounting
• Environmental Compliance: REACH Unaffected, EAR99 classification

Three active substitute parts meet these criteria. Two parts (5530132306F and 5530132300F) share an identical base product number (5530132) and differ only in viewing angle specification (45° versus unspecified). The third substitute (5530123F) maintains the original base product number (5530123) with identical electrical and optical parameters, differentiated only by packaging format and active product status.

Parameter Comparison

Engineering Selection Recommendations

5530123F is the primary substitute for the obsolete 5530123. This part maintains identical electrical, optical, and mechanical specifications while offering active product status and ROHS3 compliance. The only differentiation is packaging format (bulk versus standard). This part provides direct functional equivalence with superior supply chain availability (3673 units in stock).

5530132300F and 5530132306F are secondary substitutes derived from the 5530132 base product number. Both parts deliver identical electrical and optical performance to the main part. The distinction between these two parts is viewing angle specification (45° for both 5530132300F and 5530132306F versus unspecified for 5530123). Both maintain ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on application-specific viewing angle requirements. 5530132306F offers slightly lower inventory (995 units) compared to 5530132300F (1045 units).

For new designs or production requiring long-term supply assurance, 5530123F is the recommended selection due to direct part number lineage and highest inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5530123F be used as a direct replacement for 5530123 in existing designs?

A: Yes. The 5530123F maintains identical electrical ratings (10mA, 2.1V), optical output (16mcd green, 6.3mcd yellow), physical dimensions (3mm T-1), and mounting configuration (through-hole right-angle). The only difference is packaging format and active product status. No circuit modifications are required.

Q: What is the difference between 5530123F and the 5530132 series substitutes?

A: 5530123F shares the original 5530123 base product number and is the closest functional equivalent. The 5530132 series (5530132300F and 5530132306F) are alternative Dialight products with identical electrical and optical specifications but different base product designations. Both 5530132 variants specify a 45° viewing angle, whereas the 5530123 variants do not specify this parameter.

Q: Are all three substitute parts RoHS compliant?

A: Yes. All three substitute parts (5530123F, 5530132300F, and 5530132306F) are ROHS3 compliant. The original 5530123 does not specify RoHS status.

Q: Which substitute part should be selected for new production?

A: 5530123F is the recommended selection for new production. It maintains direct product lineage with the original 5530123, offers the highest inventory availability (3673 units), and provides active product status ensuring long-term supply continuity.

Q: Do the 5530132 series parts require any design modifications?

A: No design modifications are required. The 5530132 series maintains all critical electrical and optical parameters. The specified 45° viewing angle in these parts may provide enhanced visibility in certain mounting orientations compared to the unspecified viewing angle of the 5530123 variants, but this represents a functional enhancement rather than a limitation.

Q: What is the MSL rating for these parts?

A: All parts, including the main part and all substitutes, carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
