HSMP-3862-TR1 Equivalent & Substitute Parts

Part Overview

The HSMP-3862-TR1 is an RF Diode PIN in a 1 Pair Series Connection configuration, rated for 50V peak reverse voltage and 1A maximum current. Manufactured by Broadcom Limited, this component is packaged in SOT-23-3 (TO-236-3, SC-59) and is currently classified as obsolete. Due to its obsolete status and limited remaining inventory (1518 pcs), identifying functionally compatible substitute parts is essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for RF PIN diodes is determined by the following criteria:

Primary Compatibility Requirements:

• Diode type must be PIN - 1 Pair Series Connection
• Package must be mechanically and electrically compatible: SOT-23-3 (TO-236-3, SC-59)
• Peak reverse voltage rating must equal or exceed the application requirement (50V minimum)
• Maximum current rating must equal or exceed the application requirement (1A minimum)

Secondary Compatibility Factors:

• Capacitance and resistance characteristics should be within acceptable operating ranges for RF applications
• Operating temperature range must support the intended thermal environment

The BAR66E6327HTSA1 meets all primary compatibility requirements and is classified as an active product with improved electrical specifications and modern compliance certifications.

Engineering Selection Recommendations

The BAR66E6327HTSA1 is the manufacturer-recommended substitute for the HSMP-3862-TR1. Selection should be based on the following factors:

Product Status: The HSMP-3862-TR1 is obsolete with finite inventory. The BAR66E6327HTSA1 is an active product with substantial inventory availability (143,839 pcs), ensuring long-term supply chain reliability.

Compliance & Certifications: The BAR66E6327HTSA1 is ROHS3 compliant, meeting current regulatory requirements. Both parts maintain identical REACH and ECCN classifications (EAR99).

Electrical Performance: The substitute provides higher peak reverse voltage (150V vs. 50V), offering improved overvoltage margin. However, the maximum current rating is reduced (200 mA vs. 1 A). Circuit design must verify that the 200 mA maximum current rating is sufficient for the intended application.

Package Compatibility: Both parts use identical SOT-23-3 packaging, ensuring mechanical and thermal compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the BAR66E6327HTSA1 directly replace the HSMP-3862-TR1 without circuit modification?

A: Mechanical and thermal compatibility is direct due to identical SOT-23-3 packaging. Electrical compatibility requires verification that the application current does not exceed 200 mA. If the circuit requires the full 1 A capability of the HSMP-3862-TR1, the BAR66E6327HTSA1 is not suitable.

Q: What is the significance of the different capacitance and resistance measurement conditions?

A: Capacitance and resistance are measured at different bias points and frequencies. The HSMP-3862-TR1 measurements are taken at 50V and 100mA, while the BAR66E6327HTSA1 measurements are at 35V and 5mA. These differences reflect different operating regions and do not indicate incompatibility; however, RF circuit performance should be validated with actual component measurements in the target application.

Q: Why is the substitute rated for higher voltage but lower current?

A: The BAR66E6327HTSA1 represents a different design point within the PIN diode family. Higher voltage rating provides improved overvoltage protection, while the lower current rating reflects the component's intended application space. Selection must match the specific electrical requirements of the circuit.

Q: Is the ROHS3 compliance of the substitute a requirement for my application?

A: ROHS3 compliance is a regulatory requirement in many markets and for many customers. If your application or supply chain requires RoHS compliance, the BAR66E6327HTSA1 meets this requirement while the HSMP-3862-TR1 does not.

Q: Are there any thermal or reliability differences between these parts?

A: Both parts have identical moisture sensitivity levels (MSL 1, Unlimited) and identical REACH/ECCN classifications. Operating temperature information is not provided for the BAR66E6327HTSA1, so thermal performance comparison cannot be made from the available data.
