Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-3890-BLKG is determined by the following critical parameters:

• Diode Type: PIN - Single configuration required for RF switching and attenuation applications
• Voltage Rating: 100V peak reverse voltage minimum to maintain electrical safety margins
• Current Capacity: Minimum 500 mA acceptable; the original 1 A rating provides design margin
• Frequency Performance: Capacitance and resistance characteristics at RF frequencies (100 MHz) must support intended signal path applications
• Package Compatibility: Physical form factor and thermal characteristics must accommodate existing PCB layouts
• Moisture Sensitivity: MSL 1 rating ensures compatibility with standard storage and assembly processes

The MA4P7441F-1091T meets these substitution criteria while offering enhanced specifications in active production status.

Parameter Comparison

Engineering Selection Recommendations

The MA4P7441F-1091T serves as the manufacturer-recommended substitute for the obsolete HSMP-3890-BLKG. Selection of this alternative is supported by:

• Electrical Equivalence: Both components maintain 100V peak reverse voltage rating and PIN diode topology for RF applications
• Active Production Status: MA4P7441F-1091T is in active production, ensuring long-term availability and supply chain stability
• Compliance Certifications: MA4P7441F-1091T carries RoHS3 compliance and EAR99 export classification, matching the regulatory framework of the original component
• Thermal Performance: Operating temperature rating of 175°C exceeds the original 150°C specification, providing enhanced thermal margin
• MSL Rating: Both components share MSL 1 classification, maintaining compatibility with standard manufacturing processes

Package Consideration: The substitute uses 2-SMD packaging versus the original SOT-23-3. PCB layout modification is required to accommodate the different physical form factor.

Frequently Asked Questions (FAQ)

Q: Can MA4P7441F-1091T directly replace HSMP-3890-BLKG without circuit modification?

A: Electrical substitution is valid based on matching voltage rating, diode type, and frequency performance. However, physical package differences (2-SMD versus SOT-23-3) require PCB layout changes. Verify that the 2-SMD footprint accommodates your board design constraints.

Q: Why does the substitute have lower maximum current (500 mA vs. 1 A)?

A: The 500 mA rating of MA4P7441F-1091T remains within acceptable operating margins for PIN diode RF switching applications. Confirm that your circuit current requirements do not exceed 500 mA during normal operation.

Q: Are the capacitance and resistance values different between the two parts?

A: The parameters are measured under different bias and frequency conditions. HSMP-3890-BLKG specifies 0.3pF @ 5V, 1MHz while MA4P7441F-1091T specifies 2.2pF @ 100V, 100MHz. These differences reflect measurement methodology rather than incompatibility. Consult detailed datasheets to verify RF performance in your specific application frequency range.

Q: What is the impact of the higher operating temperature rating on reliability?

A: The MA4P7441F-1091T 175°C rating provides additional thermal headroom compared to the original 150°C specification. This supports extended operational life in thermally demanding environments.

Q: Are there any compliance or export restrictions?

A: Both components carry EAR99 classification and are subject to standard export regulations. The substitute maintains REACH Unaffected status equivalent to the original component.
