LED GREEN 525NM SMD QBHP684UE-IGU Equivalent & Substitute Parts

Part Overview

The QBHP684UE-IGU is a surface-mount LED emitter manufactured by QT Brightek (QTB) that produces green light at 525nm wavelength in a compact 1414 (3535 Metric) package. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, production continuity, and component sourcing.

The QBHP684U-XXU series delivers 110lm typical luminous flux at 350mA test current with a forward voltage of 3.4V and efficiency of 92 lm/W. The obsolete status necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete QBHP684UE-IGU is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Wavelength: 525nm (520nm – 530nm range)
• Color: Green
• Package / Case: 1414 (3535 Metric)
• Mounting Type: Surface Mount
• Current - Test: 350mA
• Voltage - Forward (Vf) Typical: 3.4V

Acceptable Variation Parameters:

• Luminous Flux: Within ±5% of 110lm at test current
• Lumens/Watt: Efficiency at or above 92 lm/W
• Current - Max: Equal to or greater than 700mA
• Physical dimensions: Footprint compatibility within 1414 package tolerance

The XPEGRN-L1-0000-00D02 (CreeLED XLamp® XP-E Green) meets all critical matching parameters and demonstrates superior performance in maximum current rating and efficiency, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Substitution Basis:

The XPEGRN-L1-0000-00D02 qualifies as a direct substitute for the obsolete QBHP684UE-IGU based on:

1. Electrical Compatibility: Identical test current (350mA), forward voltage (3.4V), and wavelength (525nm). Maximum current rating of 1A exceeds the original 700mA specification, providing design margin.

2. Optical Performance: Luminous flux of 111lm matches the original 110lm within ±1%. Efficiency of 96 lm/W exceeds the original 92 lm/W by 4.3%, indicating improved performance.

3. Mechanical Compatibility: Both components use the 1414 (3535 Metric) surface-mount package. Footprint dimensions (3.45mm vs. 3.60mm) and height (2.13mm vs. 1.90mm) are compatible with standard PCB layouts designed for this package class.

4. Regulatory Compliance: The substitute part carries RoHS Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

5. Product Status: The substitute is classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

6. Packaging Format: The substitute is supplied in Tape & Reel (TR) format, standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the XPEGRN-L1-0000-00D02 be used as a direct replacement for QBHP684UE-IGU in existing designs?

A: Yes. Both components share identical electrical specifications (350mA test current, 3.4V forward voltage, 525nm wavelength) and use the same 1414 (3535 Metric) surface-mount package. The substitute demonstrates equivalent or superior performance across all measured parameters.

Q: What are the key differences between these two parts?

A: The substitute offers higher maximum current rating (1A vs. 700mA), improved efficiency (96 lm/W vs. 92 lm/W), and active product status versus obsolete. Physical dimensions vary slightly (3.45mm vs. 3.60mm footprint; 2.13mm vs. 1.90mm height) but remain compatible within package tolerance. The substitute includes specified thermal resistance (15°C/W) and viewing angle (130°) not provided for the original part.

Q: Are there any PCB layout considerations when switching from QBHP684UE-IGU to XPEGRN-L1-0000-00D02?

A: Both parts use the 1414 (3535 Metric) package footprint. The substitute is slightly smaller in footprint (3.45mm vs. 3.60mm) and taller (2.13mm vs. 1.90mm). Existing PCB designs accommodate these variations within standard package tolerance. No layout redesign is required.

Q: Does the substitute meet current environmental regulations?

A: Yes. The XPEGRN-L1-0000-00D02 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Both parts share identical export classification (ECCN EAR99).

Q: What is the inventory status of the substitute part?

A: The XPEGRN-L1-0000-00D02 has 1013 pieces in stock as new original inventory, compared to 879 pieces of the obsolete QBHP684UE-IGU. The substitute's active product status ensures ongoing availability.

Q: How do the optical outputs compare?

A: Luminous flux is nearly identical: 111lm (substitute) versus 110lm (original), a difference of less than 1%. The substitute achieves this with higher efficiency (96 lm/W vs. 92 lm/W), indicating improved light output per unit of power consumed.

Q: Is the substitute suitable for high-current applications?

A: The substitute supports maximum current of 1A, compared to 700mA for the original part. This provides additional design margin for applications requiring higher drive currents or thermal headroom.
