Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMP-3893-TR2G is determined by the following critical parameters:

• Diode Type: PIN - 1 Pair Common Anode configuration must be maintained
• Package Compatibility: SOT-23-3 physical form factor
• Voltage Rating: Peak reverse voltage must meet or exceed 100V
• Current Capability: Maximum current rating must support application requirements
• Electrical Characteristics: Capacitance and resistance values at specified measurement conditions

The substitute parts listed below are all manufactured by MACOM Technology Solutions and maintain the same diode topology and packaging. However, they differ in voltage ratings and current specifications, requiring evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

MA4P7447CA-287T: This substitute maintains the 100V peak reverse voltage rating of the original HSMP-3893-TR2G. However, the maximum current is reduced to 150 mA compared to the original 1A specification. This part is suitable for applications where current requirements do not exceed 150 mA. The part is active and in stock with ROHS3 compliance.

MA4P7436CA-287T: This substitute operates at a reduced peak reverse voltage of 75V, which is below the original 100V specification. Selection of this part requires confirmation that the application voltage environment does not exceed 75V. Maximum current is 150 mA. This part is active, in stock, and features unlimited moisture sensitivity level (MSL 1).

MA4P7438CA-287T: This substitute provides an elevated peak reverse voltage rating of 200V, exceeding the original 100V specification. This part is suitable for applications requiring higher voltage margins. Maximum current is 150 mA. The part is active and in stock with unlimited moisture sensitivity level (MSL 1).

All substitute parts are manufactured by MACOM Technology Solutions and maintain active product status, ensuring long-term availability and support compared to the obsolete HSMP-3893-TR2G.

Frequently Asked Questions (FAQ)

Q: Can MA4P7436CA-287T be used as a direct replacement for HSMP-3893-TR2G?

A: MA4P7436CA-287T is not a direct replacement due to its reduced peak reverse voltage rating of 75V versus the original 100V. Use this substitute only if your application operates below 75V.

Q: What is the primary difference between the three substitute options?

A: The three substitutes differ primarily in peak reverse voltage ratings: MA4P7447CA-287T matches the original 100V, MA4P7436CA-287T operates at 75V, and MA4P7438CA-287T provides 200V. All three are limited to 150 mA maximum current, compared to the original 1A rating.

Q: Are all substitute parts available in the same packaging?

A: Yes, all substitute parts use SOT-23-3 packaging, maintaining physical compatibility with the original HSMP-3893-TR2G footprint.

Q: What is the impact of reduced current rating on system design?

A: The substitute parts are rated for 150 mA maximum current, significantly lower than the original 1A specification. Applications requiring currents above 150 mA cannot use these substitutes without circuit redesign.

Q: Which substitute offers the best compliance status?

A: MA4P7447CA-287T is ROHS3 compliant. The other substitutes do not specify RoHS compliance status in the provided data.

Q: How do the electrical characteristics compare at operating conditions?

A: Capacitance and resistance values differ across the substitutes due to different voltage ratings and measurement conditions. MA4P7438CA-287T exhibits the highest resistance (10Ohm) but lowest capacitance (0.35pF), while MA4P7447CA-287T shows the lowest resistance (600mOhm) but highest capacitance (1.2pF).
