HSMS-2828-BLKG Equivalent & Substitute Parts

Part Overview

The HSMS-2828-BLKG is an RF Schottky diode manufactured by Broadcom Limited, designed for RF applications requiring a 1 Bridge configuration with 15V peak reverse voltage rating and 1A maximum current capacity. This component is packaged in SOT-143-4 (TO-253-4, TO-253AA) format. The product is currently classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy component specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMS-2828-BLKG is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode Type: Schottky configuration
• Voltage - Peak Reverse (Max): Must equal or exceed 15V
• Current - Max: Must equal or exceed 1A
• Capacitance @ Vr, F: 1pF @ 0V, 1MHz (matching RF characteristics)
• Package compatibility: Physical form factor must accommodate SOT-143-4 or equivalent footprint

Secondary Considerations:

• Resistance @ If, F: Forward resistance characteristics at specified bias conditions
• Operating Temperature range: Must support the application's thermal requirements
• Product Status: Active status preferred for long-term availability

The MADS-001338-12790T from MACOM Technology Solutions is identified as a manufacturer-recommended substitute. However, this part exhibits reduced electrical ratings (8V peak reverse voltage, 30mA maximum current) compared to the original specification, indicating it functions as a substitute only for applications operating within these lower parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

Original Part (HSMS-2828-BLKG): The HSMS-2828-BLKG is Obsolete and no longer in active production. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. This part remains suitable for maintenance and repair of legacy systems where original specifications must be preserved.

Substitute Part (MADS-001338-12790T): The MADS-001338-12790T is Active and manufactured by MACOM Technology Solutions. This part is suitable for new designs and ongoing production where electrical requirements align with its reduced ratings (8V maximum reverse voltage, 30mA maximum current). The substitute maintains matching RF characteristics (1pF capacitance) and is lead-free, supporting modern manufacturing compliance requirements. Package differences (SC-79 vs. SOT-143-4) require PCB layout verification.

Selection Basis:

• For legacy system support: Retain HSMS-2828-BLKG where original specifications are mandatory
• For new designs or upgrades: MADS-001338-12790T is recommended where application voltage and current requirements do not exceed 8V and 30mA respectively
• Compliance: MADS-001338-12790T is lead-free; HSMS-2828-BLKG compliance status not specified in available data

Frequently Asked Questions (FAQ)

Q: Can MADS-001338-12790T directly replace HSMS-2828-BLKG in all applications?

A: No. The MADS-001338-12790T has lower electrical ratings (8V vs. 15V peak reverse voltage; 30mA vs. 1A maximum current). Direct substitution is only valid for applications operating within these reduced parameters. Verify your circuit's voltage and current requirements before substitution.

Q: What are the package differences between these parts?

A: HSMS-2828-BLKG uses SOT-143-4 (TO-253-4, TO-253AA) packaging. MADS-001338-12790T uses SC-79 or SOD-523 packaging. These are physically different form factors requiring PCB layout modifications and footprint verification.

Q: Why is HSMS-2828-BLKG classified as Obsolete?

A: Broadcom Limited has discontinued this product line. Existing stock may be available through distributors, but new production is not available. For new designs, active alternatives must be evaluated.

Q: Are there other substitutes available?

A: Only MADS-001338-12790T is identified as a manufacturer-recommended substitute in the provided data. Additional alternatives may exist; consult component datasheets and application requirements for comprehensive evaluation.

Q: What is the impact of operating temperature differences?

A: HSMS-2828-BLKG supports junction temperatures to 150°C. MADS-001338-12790T operates from -55°C to 125°C. Verify your application's thermal environment falls within the substitute's operating range.

Q: Is MADS-001338-12790T lead-free?

A: Yes. MADS-001338-12790T is specified as lead-free, supporting RoHS and modern manufacturing compliance requirements.
