HLMP-CE25-Z2CDD Equivalent & Substitute Parts

Part Overview

The HLMP-CE25-Z2CDD is a cyan 505nm LED indicator manufactured by Broadcom Limited, configured as a discrete through-hole component in T-1 3/4 (5mm) package format. This part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain identical optical, electrical, and mechanical characteristics to ensure direct compatibility in existing circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the HLMP-CE25-Z2CDD are qualified based on the following criteria:

• Color and Wavelength Match: Cyan color with dominant wavelength of 505nm and peak wavelength of 501nm
• Optical Intensity: 19500mcd millicandela rating
• Lens Configuration: 5mm T-1 3/4 round domed clear lens
• Viewing Angle: 23° viewing angle
• Mounting Configuration: Through-hole radial package
• Physical Dimensions: Maximum height of 12.45mm
• Electrical Compatibility: Forward voltage and test current parameters within acceptable operating range
• Environmental Classification: MSL 1 (Unlimited) moisture sensitivity

The substitute parts identified (HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD) maintain all optical and mechanical parameters identical to the main part. The primary difference is forward voltage specification (3.0V versus 3.2V), which represents a minor electrical variation within acceptable design tolerance for LED indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Both HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD are active product alternatives to the obsolete HLMP-CE25-Z2CDD. Selection between these substitutes should be based on:

Product Status: The substitute parts carry active product status, ensuring ongoing availability and manufacturing support compared to the obsolete main part.

Compliance Certifications: HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD both maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the regulatory profile of the original part.

Electrical Specification: The forward voltage difference (3.0V versus 3.2V) represents a 0.2V reduction. This variation is within typical LED tolerance ranges and does not affect functional compatibility in standard indicator circuit designs. Circuit designs with tight voltage regulation or specific current-limiting resistor calculations should account for this minor difference.

Inventory Availability: HLMP-CE21-Z2QDD maintains higher inventory levels (833 Pcs) compared to HLMP-CE21-Z2CDD (742 Pcs), supporting procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD be used interchangeably with HLMP-CE25-Z2CDD?

A: Yes. Both substitute parts maintain identical optical characteristics (color, wavelength, intensity, lens configuration, viewing angle) and mechanical dimensions (package, height, mounting type). The 0.2V forward voltage difference does not prevent direct substitution in standard LED indicator applications.

Q: What is the significance of the forward voltage difference between 3.2V and 3.0V?

A: The forward voltage specification indicates the typical voltage drop across the LED when operating at the test current (20mA). The 0.2V difference is minor and falls within normal LED manufacturing tolerances. Existing circuit designs using current-limiting resistors will continue to function correctly with the substitute parts.

Q: Why is the main part classified as obsolete?

A: Obsolete status indicates that the HLMP-CE25-Z2CDD is no longer manufactured or supported by Broadcom Limited. The identified substitute parts (HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD) represent the active product line continuation for this LED indicator category.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.41.0000). The substitute parts add ROHS3 compliance certification, which represents an enhancement to the regulatory profile.

Q: What is the difference between HLMP-CE21-Z2CDD and HLMP-CE21-Z2QDD?

A: Both parts are parametrically equivalent with identical electrical, optical, and mechanical specifications. The difference in part number suffix (Z2CDD versus Z2QDD) reflects internal Broadcom manufacturing or packaging variations. Selection between these parts can be based on inventory availability or specific procurement requirements.

Q: Is the T-1 3/4 package compatible with existing PCB designs for the HLMP-CE25-Z2CDD?

A: Yes. Both substitute parts maintain the identical T-1 3/4 (5mm) through-hole radial package configuration, maximum height of 12.45mm, and mounting specifications. Direct PCB footprint compatibility is maintained.
