Key Parameters

Substitute Part Grouping Explanation

Substitution for the QSMH-C176 is based on the following criteria derived from provided parameters:

Primary Substitution Criteria:

• LED Indication discrete device classification
• Broadcom Limited manufacturer origin
• Obsolete product status requiring active replacement
• Compliance with EAR99 export classification
• HTSUS code alignment (8541.41.0000)
• ROHS3 compliance requirement

The identified substitute HSMH-C170 shares the same manufacturer, product category classification, export control designation, and tariff code. Both components are classified as obsolete, confirming the necessity for substitution in active designs.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute components for the obsolete QSMH-C176 must be based on the following engineering criteria:

Compliance Alignment: Both QSMH-C176 and HSMH-C170 maintain identical ECCN classification (EAR99) and HTSUS tariff code (8541.41.0000), ensuring regulatory consistency in component substitution.

RoHS Compliance: Both components are ROHS3 compliant, satisfying environmental and hazardous substance restrictions applicable to electronic components.

Product Status Consideration: Both components carry obsolete product status. This indicates that neither component is in active production. Component selection must account for available inventory levels and long-term supply chain implications.

Packaging and Mounting Differences: The QSMH-C176 is specified as a top mount chip LED, while the HSMH-C170 is a surface mount 0805 (2012 Metric) package. Design integration requires evaluation of PCB layout compatibility and mounting process alignment with existing manufacturing procedures.

Electrical Parameter Specification: The HSMH-C170 provides complete electrical parameter documentation including forward voltage (1.8V), test current (20mA), wavelength specifications (639nm dominant, 660nm peak), and optical characteristics (17mcd, 170° viewing angle). The QSMH-C176 electrical parameters are not provided in available documentation, requiring design review to confirm compatibility with application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the QSMH-C176 listed as obsolete?

A: The QSMH-C176 is designated as obsolete by Broadcom Limited, indicating the component is no longer in active production. Obsolete status requires identification and qualification of substitute components for ongoing applications.

Q: What makes HSMH-C170 a valid substitute for QSMH-C176?

A: Both components share identical manufacturer (Broadcom Limited), product category (LED Indication - Discrete), export classification (EAR99), tariff code (8541.41.0000), and RoHS compliance status (ROHS3). These parameters establish functional and regulatory equivalence for substitution purposes.

Q: Are there packaging differences between these components?

A: Yes. The QSMH-C176 is specified as a top mount chip LED, while the HSMH-C170 is a surface mount 0805 (2012 Metric) package. PCB design and assembly process modifications are required to accommodate this packaging difference.

Q: What electrical parameters should be verified for substitution?

A: The HSMH-C170 operates at 1.8V forward voltage with 20mA test current, produces 17mcd at 639nm dominant wavelength, and provides 170° viewing angle. These parameters must be evaluated against the original application requirements to confirm functional compatibility.

Q: Is the HSMH-C170 currently available?

A: The HSMH-C170 is also designated as obsolete. However, inventory data indicates 101,200 pieces are available in stock as new original components, providing near-term supply availability despite obsolete product status.

Q: What compliance certifications apply to both components?

A: Both QSMH-C176 and HSMH-C170 are ROHS3 compliant and classified under EAR99 export control. Both are subject to HTSUS tariff code 8541.41.0000. These certifications ensure regulatory alignment for component substitution.

Q: Are there additional substitute options available?

A: The HSMH-C170 documentation identifies additional substitute components including CMDA5AR7D1S, CMDA5DR7D1S, BR1112H-TR, HSMH-H170, and 7012X1. These alternatives require individual evaluation against application-specific requirements.
