Key Parameters

Substitute Part Grouping Explanation

Substitution of the EAHC2835WD1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Warm
• CCT: 3000K
• Luminous Flux @ 25°C, 150mA: 60 lm (50–70 lm range)
• Forward Voltage (Vf) Typical: 3.1V
• Test Current: 150mA
• Maximum Current: 180mA
• CRI: 90
• Viewing Angle: 120°
• Package / Case: 1411 (3528 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 3.50 × 2.80 × 0.85 mm
• Thermal Resistance: 21°C/W

Two substitute parts meet these criteria and are classified as follows:

MFR Recommended Substitute: 67-21S/HK4C-H3030R1R42834Z15/2T (Active status, standard packaging)

Parametric Equivalent: 67-21S/HK4C-3H3030R1R42834Z15/2T/EU (Active status, Tape & Reel packaging)

Both substitutes are manufactured by Everlight Electronics Co Ltd and maintain identical electrical and mechanical specifications to the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Electrical Performance):

Use 67-21S/HK4C-H3030R1R42834Z15/2T when standard packaging is required. This part is active in production, ensuring long-term availability and supply chain continuity. All electrical parameters, thermal characteristics, and mechanical dimensions are identical to the EAHC2835WD1. The part is suitable for direct PCB substitution without circuit modification.

For High-Volume or Automated Assembly Applications:

Use 67-21S/HK4C-3H3030R1R42834Z15/2T/EU when Tape & Reel packaging is specified for pick-and-place assembly processes. This part maintains identical electrical and mechanical specifications while offering packaging optimization for automated manufacturing. The /EU designation indicates compliance with European standards and regulations.

Compliance Considerations:

Both substitute parts are manufactured by the same original equipment manufacturer (Everlight Electronics Co Ltd), ensuring design continuity and performance consistency. The EAHC2835WD1 is ROHS3 compliant; compliance status for substitute parts should be verified against specific procurement requirements if regulatory certification is mandatory for the end application.

Availability and Supply Chain:

The EAHC2835WD1 is classified as obsolete. Both substitute parts are active in production with confirmed inventory availability (823 and 897 units respectively), providing reliable procurement pathways for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the 67-21S/HK4C-H3030R1R42834Z15/2T be used as a direct replacement for EAHC2835WD1 in existing designs?

A: Yes. The substitute part is electrically and mechanically identical. Forward voltage, luminous flux, current ratings, viewing angle, package dimensions, and thermal characteristics are equivalent. No circuit modifications are required.

Q: What is the difference between the two substitute parts?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format: 67-21S/HK4C-H3030R1R42834Z15/2T uses standard packaging, while 67-21S/HK4C-3H3030R1R42834Z15/2T/EU is supplied in Tape & Reel format optimized for automated assembly. The /EU designation indicates European regulatory compliance.

Q: Which substitute should be selected for new product designs?

A: For new designs, either substitute is acceptable based on assembly requirements. Select Tape & Reel packaging (67-21S/HK4C-3H3030R1R42834Z15/2T/EU) for automated pick-and-place assembly. Select standard packaging (67-21S/HK4C-H3030R1R42834Z15/2T) for manual assembly or when packaging format is not a constraint.

Q: Are the substitute parts RoHS compliant?

A: The EAHC2835WD1 is ROHS3 compliant. RoHS compliance status for substitute parts is not specified in the provided data. Verify compliance documentation with the supplier if regulatory certification is required for the end application.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. Both substitute parts use the identical 1411 (3528 Metric) package with dimensions of 3.50 × 2.80 × 0.85 mm. PCB footprints and solder pad layouts are compatible without modification.

Q: What is the thermal performance difference between the main part and substitutes?

A: Thermal resistance is identical at 21°C/W for all three parts. Thermal management design and heat dissipation calculations remain unchanged when substituting.

Q: Are there any electrical parameter differences that affect circuit design?

A: No. Forward voltage (3.1V typical), test current (150mA), maximum current (180mA), and luminous efficacy (129 lm/W) are identical across all three parts. Circuit design, current limiting resistor values, and power supply specifications require no modification.

Q: Can the substitute parts be mixed in the same production batch?

A: Yes, provided the application does not require specific packaging format. Both substitute parts are electrically and mechanically equivalent. However, if automated assembly is used, maintain consistent packaging format (Tape & Reel) throughout the production run to avoid assembly line configuration changes.
