Dialight 5710133 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5710133 is a 2mm bi-level yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features dual yellow LEDs in a single package with diffused, tinted optics and operates at 2.1V with 20mA current rating. The part is currently classified as obsolete, making identification of suitable alternatives essential for ongoing design support and production continuity. Active equivalent and similar substitute options are available from both the original manufacturer and alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5710133 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Dialight 5710133F): This substitute maintains identical electrical specifications including wavelength (585nm), current (20mA), voltage (2.1V), configuration (2 High), and mounting type (Through Hole, Right Angle). The primary differences are product status (Active vs. Obsolete), packaging format (Bulk), and improved compliance certifications (ROHS3 Compliant, MSL 1 Unlimited vs. RoHS non-compliant, MSL 2).

Similar Substitute (Kingbright WP4060VH/2YD): This substitute maintains compatibility in core electrical parameters: color (Yellow x 2), configuration (2 High), current (20mA), voltage (2.1V), and mounting type (Through Hole, Right Angle). Acceptable variations include wavelength (588nm vs. 585nm, within yellow LED spectrum), millicandela rating (6mcd vs. 12.6mcd, lower brightness), viewing angle (70° vs. 38°, wider), and lens style (Round with Domed Top vs. standard diffused). Physical size differs at 1.80mm diameter versus 2mm.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The Dialight 5710133F is the primary substitute for the obsolete 5710133. Both parts share identical electrical and optical specifications, ensuring functional equivalence in existing circuit designs. The 5710133F offers improved product status (Active), enhanced RoHS compliance (ROHS3 Compliant), and superior moisture handling (MSL 1 Unlimited vs. MSL 2 1 Year). This part is recommended for new designs and production continuity where the original specification must be maintained.

For Design Flexibility: The Kingbright WP4060VH/2YD provides a viable alternative when circuit design permits tolerance of specified parameter variations. This part maintains electrical compatibility (20mA, 2.1V, 2 High configuration) and mounting type (Through Hole, Right Angle) but operates with reduced brightness (6mcd vs. 12.6mcd) and wider viewing angle (70° vs. 38°). The 1.80mm lens diameter differs from the 2mm specification. This substitute is suitable for applications where brightness reduction and expanded viewing angle are acceptable trade-offs. Both substitute options carry ROHS3 compliance and MSL 1 ratings, supporting modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5710133F directly replace the 5710133 in existing designs? A: Yes. The 5710133F maintains identical electrical specifications (20mA, 2.1V), optical characteristics (585nm wavelength, 12.6mcd, 38° viewing angle), configuration (2 High), and mounting type (Through Hole, Right Angle). No circuit modifications are required.

Q: What are the key differences between the 5710133 and 5710133F? A: The primary differences are product status (Obsolete vs. Active), packaging (standard vs. Bulk), RoHS compliance (non-compliant vs. ROHS3 Compliant), and moisture sensitivity level (MSL 2 1 Year vs. MSL 1 Unlimited). Electrical and optical performance are identical.

Q: When is the Kingbright WP4060VH/2YD appropriate as a substitute? A: This part is suitable when circuit design can accommodate reduced brightness (6mcd vs. 12.6mcd), wider viewing angle (70° vs. 38°), and smaller lens diameter (1.80mm vs. 2mm). Electrical parameters (20mA, 2.1V, 2 High configuration) and mounting type remain compatible.

Q: Are there packaging considerations when switching between these parts? A: The 5710133F is supplied in Bulk packaging, while the original 5710133 packaging format is not specified. The Kingbright WP4060VH/2YD packaging format is also not specified. Verify packaging requirements with your procurement process.

Q: Do all substitute parts meet current compliance standards? A: Both the Dialight 5710133F and Kingbright WP4060VH/2YD are ROHS3 Compliant with MSL 1 (Unlimited) ratings. The original 5710133 is RoHS non-compliant with MSL 2 (1 Year). For new designs and modern manufacturing environments, the substitute parts offer improved compliance.

Q: What is the wavelength difference between 585nm and 588nm? A: Both wavelengths fall within the yellow LED spectrum and are visually indistinguishable to the human eye. The 3nm difference is within standard LED manufacturing tolerances and does not affect functional performance in indicator applications.
