Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete QSMG-C19R is based on functional equivalence within the discrete LED indication category. The primary substitute, HSMG-C191, is manufactured by the same supplier (Broadcom Limited) and maintains compatibility through standardized electrical and mechanical parameters applicable to LED components.

The substitution logic is determined by the following key parameters:

• Manufacturer Alignment: Both parts are Broadcom Limited products, ensuring consistent design philosophy and quality standards
• Product Category: Both components function as discrete LED indication devices
• Compliance Certifications: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications
• Regulatory Status: Both parts maintain RoHS3 compliance and REACH unaffected status
• Packaging Type: The substitute utilizes standard Surface Mount Device (SMD) packaging with Cut Tape and Digi-Reel options for production flexibility

Engineering Selection Recommendations

The HSMG-C191 is the manufacturer-recommended substitute for the obsolete QSMG-C19R. Selection of this active component is supported by the following engineering factors:

Product Status Alignment: The HSMG-C191 maintains active production status with Broadcom Limited, ensuring continuous availability and long-term supply chain stability compared to the obsolete QSMG-C19R.

Regulatory Compliance: Both components share identical export control classifications (ECCN: EAR99) and tariff codes (HTSUS: 8541.41.0000), eliminating compliance complications during transition.

Quality Certifications: The HSMG-C191 carries explicit RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Inventory Availability: The substitute component maintains significantly higher inventory levels (89,690 pieces) compared to the obsolete part (630 pieces), providing production security and reducing lead time risk.

Supplier Continuity: Maintaining the Broadcom Limited manufacturer relationship ensures consistent quality standards, technical support, and design documentation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HSMG-C191 directly replace the QSMG-C19R in existing designs?

A: The HSMG-C191 is the manufacturer-recommended substitute for the QSMG-C19R. Both components are discrete LED indication devices from Broadcom Limited with identical regulatory classifications. The substitute operates as a Surface Mount Device in 0603 (1608 Metric) package format with specified electrical parameters (2.2V forward voltage, 20mA test current, 572nm dominant wavelength, 15mcd brightness rating).

Q: What are the key electrical parameters of the substitute component?

A: The HSMG-C191 substitute provides the following electrical specifications: forward voltage of 2.2V (typical), test current of 20mA, dominant wavelength of 572nm (green), peak wavelength of 570nm, millicandela rating of 15mcd, and viewing angle of 170°.

Q: What packaging options are available for the HSMG-C191?

A: The HSMG-C191 is supplied in Cut Tape (CT) and Digi-Reel packaging formats. The component utilizes 0603 (1608 Metric) package format with physical dimensions of 1.60mm length by 0.80mm width and maximum height of 0.60mm.

Q: Are there compliance or regulatory differences between the obsolete and substitute parts?

A: Both the QSMG-C19R and HSMG-C191 carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The HSMG-C191 explicitly maintains RoHS3 compliance and REACH unaffected status. Moisture sensitivity level for the substitute is rated at 2A (4 weeks).

Q: What is the supply status difference between these components?

A: The QSMG-C19R is classified as obsolete with 630 pieces currently in stock. The HSMG-C191 maintains active production status with 89,690 pieces in inventory, providing substantially improved availability for ongoing production requirements.

Q: Are there any mechanical compatibility considerations for PCB layout?

A: The HSMG-C191 is a Surface Mount Device in 0603 (1608 Metric) package format. PCB footprints must accommodate these specific dimensions: 1.60mm length, 0.80mm width, and 0.60mm maximum height. Standard 0603 SMD land patterns are compatible with this component.
