Equivalent & Substitute Parts for DF3SYKD LED Indicator Bar

Part Overview

The DF3SYKD is an active yellow LED circuit board indicator bar manufactured by Kingbright. This through-hole mounted component features a single DIP configuration with a diffused, tinted lens and rectangular flat-top design measuring 19.90mm x 6.80mm. The component operates at 2V with a 175mA current rating and delivers 350mcd luminous intensity at a peak wavelength of 590nm. This part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3SYKD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow (590nm wavelength range acceptable)
• Configuration: Bar - Single format
• Mounting Type: Through Hole
• Lens Style: Rectangle with Flat Top
• Voltage Rating: 2V nominal operation
• Product Status: Active

Secondary Consideration Parameters:

• Current Rating: 175mA (DF3SYKD) versus 25mA (HLMP-2450)
• Millicandela Rating: 350mcd (DF3SYKD) versus 38mcd (HLMP-2450)
• Lens Size: 19.90mm x 6.80mm (DF3SYKD) versus 19.05mm x 3.81mm (HLMP-2450)
• Configuration Variant: DIP (DF3SYKD) versus SIP (HLMP-2450)

The HLMP-2450 substitute shares the core functional category (yellow LED indicator bar, through-hole mounted, rectangular flat-top lens) and operates within compatible voltage parameters. However, significant differences exist in current draw, luminous intensity, physical dimensions, and pin configuration that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the DF3SYKD and HLMP-2450 maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity ratings, ensuring regulatory and environmental compatibility. Selection between these components must account for the following engineering considerations:

DF3SYKD Selection Criteria:

• Applications requiring 175mA current capacity
• Designs demanding 350mcd luminous intensity output
• PCB layouts accommodating 19.90mm x 6.80mm lens dimensions
• DIP pin configuration compatibility with existing footprints

HLMP-2450 Selection Criteria:

• Applications with 25mA current budget constraints
• Designs tolerating 38mcd luminous intensity
• PCB layouts accommodating 19.05mm x 3.81mm lens dimensions
• SIP pin configuration compatibility with existing footprints
• Systems operating at 2.1V nominal voltage

Both components operate within the yellow LED spectrum (583nm to 590nm peak wavelength) and share rectangular flat-top lens geometry. The HLMP-2450 represents a lower-power, lower-intensity alternative suitable for applications where the DF3SYKD's performance specifications exceed functional requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-2450 directly replace DF3SYKD in existing designs?

A: Direct replacement requires verification of three critical factors: (1) PCB footprint compatibility between DIP and SIP pin configurations, (2) circuit current capacity adjustment from 175mA to 25mA, and (3) optical performance acceptance of 38mcd versus 350mcd luminous intensity. Physical lens dimensions also differ (19.90mm x 6.80mm versus 19.05mm x 3.81mm).

Q: What are the key electrical differences between these components?

A: The DF3SYKD operates at 2V with 175mA current rating, while the HLMP-2450 operates at 2.1V with 25mA current rating. This represents a 7x reduction in current draw and 9.2x reduction in luminous intensity. Peak wavelengths differ by 7nm (590nm versus 583nm), both within the yellow spectrum.

Q: Are both components suitable for new designs?

A: Yes. Both components carry active product status and ROHS3 compliance. Selection should be based on application-specific requirements for current consumption, luminous intensity, physical dimensions, and pin configuration compatibility.

Q: What mounting considerations apply to substitution?

A: Both components use through-hole mounting. However, DIP and SIP configurations require different PCB hole patterns and spacing. Mechanical fit verification is necessary before substitution, particularly regarding lens size differences and board clearance.

Q: Do compliance certifications differ between these parts?

A: No. Both components are ROHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity ratings, and maintain REACH unaffected status. Regulatory compliance is equivalent.
