Dialight 5552001 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5552001 is a single red LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a 2.00mm diameter diffused, tinted lens with a domed top and operates at 1.6V with a 50mA current rating. The part is classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5552001 is determined by strict equivalence across the following critical parameters:

• Optical Characteristics: Color (Red), wavelength peak (655nm), lens type (Diffused, Tinted), lens style (Round with Domed Top), and lens size (2.00mm Dia) must remain identical
• Electrical Specifications: Current rating (50mA) and voltage rating (1.6V) must match exactly
• Mechanical Compatibility: Mounting type (Through Hole, Right Angle) and configuration (Single) must be preserved
• Performance Metrics: Millicandela rating (0.6mcd) and viewing angle (35°) must be maintained

The substitute part 5552001F meets all these criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5552001F is the direct equivalent substitute for the obsolete 5552001. Both parts are functionally identical across all electrical, optical, and mechanical parameters. The primary distinction is product status and regulatory compliance: the 5552001F is an active product with ROHS3 compliance, whereas the 5552001 is obsolete and RoHS non-compliant. For new designs and ongoing production, the 5552001F should be selected to ensure supply chain continuity and compliance with current environmental regulations. Both parts maintain identical moisture sensitivity levels and international trade classifications.

Frequently Asked Questions (FAQ)

Q: Can the 5552001F be used as a direct replacement for the 5552001 in existing designs?

A: Yes. The 5552001F is electrically and mechanically identical to the 5552001. All optical characteristics, current ratings, voltage ratings, mounting configurations, and physical dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from 5552001 to 5552001F?

A: The 5552001 is classified as obsolete, creating supply chain risk. The 5552001F is an active product with current manufacturing support and improved RoHS3 compliance status, ensuring long-term availability and regulatory alignment.

Q: Are there packaging differences between these parts?

A: The 5552001 is supplied in standard packaging, while the 5552001F is supplied in bulk packaging. Both maintain identical component specifications and performance characteristics.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both the 5552001 and 5552001F carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.

Q: Are there compliance or certification differences?

A: The 5552001F carries ROHS3 compliance certification, while the 5552001 is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications. For applications subject to RoHS regulations, the 5552001F is the appropriate selection.
