Substitute Part Grouping Explanation

Substitution of the QLMP-CE45-YZCDD is determined by the following criteria based on provided parameters:

• Manufacturer Alignment: Broadcom Limited maintains product line continuity through the HLMP series, which represents the active production equivalent to the obsolete QLMP series
• Color Specification: Cyan wavelength requirement (505nm dominant wavelength) is maintained in the substitute part
• Package Category: Both parts are discrete LED indicators in 5mm form factor
• Regulatory Compliance: REACH Unaffected and EAR99 ECCN classification are consistent across both parts
• Trade Classification: HTSUS code 8541.41.0000 applies to both components

The HLMP-CE21-Z2CDD is the manufacturer-recommended substitute, providing active production status with full technical specifications available for design integration.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-CE21-Z2CDD is designated as the manufacturer-recommended substitute for the obsolete QLMP-CE45-YZCDD. Selection of this substitute is supported by the following factors:

• Active Production Status: The HLMP-CE21-Z2CDD maintains active product status with current manufacturing and supply chain availability, eliminating obsolescence risk
• Regulatory Compliance: Both components share identical REACH and ECCN classifications, ensuring no change to regulatory documentation or export compliance requirements
• Trade Classification Consistency: HTSUS code alignment confirms tariff and customs classification continuity
• Manufacturer Continuity: Broadcom Limited provides direct product line succession from the QLMP to HLMP series, ensuring engineering support and documentation consistency

The substitute part provides complete technical specifications for circuit design integration, including forward voltage, test current, optical output, and mechanical dimensions necessary for PCB layout and assembly planning.

Frequently Asked Questions (FAQ)

Q: Why is the QLMP-CE45-YZCDD obsolete? A: The QLMP-CE45-YZCDD has reached end-of-life status within Broadcom Limited's product portfolio. The HLMP series represents the current production equivalent for cyan LED indication applications.

Q: What are the key compatibility factors between QLMP-CE45-YZCDD and HLMP-CE21-Z2CDD? A: Both components are cyan LED indicators in 5mm form factor manufactured by Broadcom Limited. They share identical regulatory classifications (REACH Unaffected, EAR99 ECCN) and trade codes (HTSUS 8541.41.0000). The substitute provides complete electrical and optical specifications for design integration.

Q: Is the HLMP-CE21-Z2CDD a direct pin-for-pin replacement? A: Both components utilize through-hole radial mounting with standard LED polarity (anode/cathode configuration). The HLMP-CE21-Z2CDD specifies 3V forward voltage and 20mA test current, which must be verified against your circuit design requirements.

Q: What is the mechanical difference between these parts? A: The HLMP-CE21-Z2CDD specifies a maximum height of 12.45mm with T-1 3/4 (5mm) lens size and round domed top lens style. These dimensions must be confirmed compatible with existing PCB layouts and mechanical assemblies.

Q: Are there any compliance differences? A: The HLMP-CE21-Z2CDD carries ROHS3 compliance certification, while the obsolete QLMP-CE45-YZCDD does not specify RoHS status. Both maintain REACH Unaffected status and identical ECCN classification.

Q: What is the optical output difference? A: The HLMP-CE21-Z2CDD specifies 19500mcd at 20mA test current with 505nm dominant wavelength and 23° viewing angle. These parameters must be evaluated against your application's brightness and visibility requirements.
