ASMT-QHBE-APQ0E Equivalent & Substitute Parts

Part Overview

The ASMT-QHBE-APQ0E is a 4-PLCC surface mount LED manufactured by Broadcom Limited. This part is classified as obsolete, making identification of functionally equivalent substitutes necessary for ongoing design support and procurement. The original part number lacks complete specification data in available documentation, which is typical for legacy LED components. Substitute parts must maintain compatibility with the 4-PLCC package footprint and surface mount assembly requirements.

Substitute Part Grouping Explanation

Substitution for the ASMT-QHBE-APQ0E is based on the following criteria:

Package Compatibility: The substitute part must use the 4-PLCC package to ensure PCB footprint and assembly process compatibility.

Mounting Type: Surface mount technology is required to match the original assembly method.

Manufacturer Consistency: Broadcom Limited manufacture ensures design validation and supply chain continuity.

Compliance Standards: RoHS3 compliance and EAR99 export classification must be maintained.

Moisture Sensitivity: MSL rating of 2 (1 Year) establishes handling and storage requirements.

The identified substitute ASMT-QHBD-AFH0E meets all these criteria while providing complete electrical specifications for design verification.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-QHBD-AFH0E is the qualified substitute for ASMT-QHBE-APQ0E based on:

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical export classification (EAR99), ensuring no regulatory barriers to substitution.

Supply Chain Continuity: Both parts share the same base product number (ASMT-QHB) and manufacturer, indicating design lineage within the Broadcom LED product family.

Physical Compatibility: Identical 4-PLCC package and surface mount configuration guarantee PCB footprint compatibility without layout modifications.

Handling Requirements: Matching MSL ratings ensure identical moisture control procedures during storage and assembly.

The substitute part provides complete electrical specifications (color, wavelength, forward voltage, luminous flux, and thermal characteristics) that were not available for the original part number, enabling full design validation.

Frequently Asked Questions (FAQ)

Q: Why is the ASMT-QHBE-APQ0E obsolete? A: Both the original part and its substitute are classified as obsolete by Broadcom Limited. This is typical for LED components as product lines are updated. The substitute provides a documented alternative within the same product family.

Q: Will the ASMT-QHBD-AFH0E fit the same PCB footprint? A: Yes. Both parts use the 4-PLCC package with identical physical dimensions (0.126" L x 0.110" W, height 0.083" max), ensuring direct PCB compatibility without layout changes.

Q: Are there any compliance concerns with substitution? A: No. Both parts are ROHS3 compliant with identical EAR99 export classification and HTSUS codes. Substitution does not introduce regulatory or compliance issues.

Q: What are the moisture handling requirements? A: Both parts carry MSL rating 2 (1 Year), requiring storage at ≤30% relative humidity and use within one year of package opening. Standard moisture control procedures apply.

Q: What electrical specifications should I verify for the substitute? A: The ASMT-QHBD-AFH0E is specified as a red LED (618nm wavelength) with 2.5V typical forward voltage, 150mA test current, and 24lm luminous flux. Verify these specifications match your circuit design requirements before implementation.

Q: Can I use the ASMT-QHBD-AGH0E as an alternative? A: The ASMT-QHBD-AFH0E documentation indicates ASMT-QHBD-AGH0E as a further substitute option. Consult Broadcom product documentation for compatibility details between these variants.
