Key Parameters

Substitute Part Grouping Explanation

Substitution for the QL205YD is determined by the following critical parameters:

• Mounting Type: Through Hole (required match)
• Package / Case: Radial configuration (required match)
• Supplier Device Package: T-1 (3mm) form factor (required match)
• Color: Yellow LED indication (required match)
• Application: LED indication - discrete radial component (required match)

The HLMP-1401 from Broadcom Limited qualifies as a direct substitute based on matching all mandatory parameters. Both components share identical mounting methodology, package geometry, and functional purpose as yellow LED indicators in T-1 through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-1401 is the qualified substitute for the obsolete QL205YD. Selection is based on the following engineering criteria:

Product Status: The QL205YD is obsolete, necessitating transition to an active component. The HLMP-1401 maintains active product status with ongoing manufacturer support and availability.

Compliance & Certifications: The HLMP-1401 achieves ROHS3 compliance, whereas the QL205YD is RoHS non-compliant. Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.41.0000), ensuring regulatory alignment for international applications.

Physical Compatibility: Both components utilize T-1 (3mm) through-hole radial packages with identical mounting methodology. The HLMP-1401 height of 6.35mm versus the QL205YD height of 5.20mm represents a 1.15mm difference. This dimensional variance must be evaluated within specific PCB layout constraints and mechanical clearance requirements.

Inventory & Availability: The HLMP-1401 demonstrates significantly higher inventory availability (27,190 pcs) compared to the QL205YD (1,036 pcs), supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-1401 directly replace the QL205YD in existing designs?

A: The HLMP-1401 matches the QL205YD in mounting type (through hole), package configuration (radial), and form factor (T-1 3mm). The primary consideration is the height difference of 1.15mm (HLMP-1401 at 6.35mm maximum height versus QL205YD at 5.20mm maximum height). PCB layout and mechanical clearance must accommodate this dimensional variance.

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

A: The primary differences are product status (QL205YD is obsolete; HLMP-1401 is active), RoHS compliance (QL205YD is non-compliant; HLMP-1401 is ROHS3 compliant), and maximum height (5.20mm versus 6.35mm). Both share identical moisture sensitivity level, REACH status, ECCN classification, and HTSUS code.

Q: Are there any compliance concerns when substituting the QL205YD with the HLMP-1401?

A: The HLMP-1401 provides improved compliance through ROHS3 certification. Both components maintain identical REACH status (REACH Unaffected) and export classification (EAR99), ensuring regulatory alignment for international markets.

Q: What packaging options are available for the HLMP-1401?

A: The HLMP-1401 is supplied in bulk packaging. The QL205YD packaging specification was not provided in the available data.

Q: How does inventory availability affect component selection?

A: The HLMP-1401 maintains substantially higher inventory levels (27,190 pcs) relative to the QL205YD (1,036 pcs), supporting extended production runs and reducing supply chain risk for new designs or production continuity initiatives.
