Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-2852-TR1G is determined by the following critical parameters:

• Diode Type: Schottky - 1 Pair Series Connection (all substitutes must match this configuration)
• Package / Case: TO-236-3, SC-59, SOT-23-3 (physical and electrical compatibility)
• Voltage - Peak Reverse (Max): 2V or higher (electrical rating compatibility)
• Capacitance @ Vr, F: Similar range to support RF performance
• Operating Temperature: Minimum 150°C (TJ) to maintain thermal compatibility
• Moisture Sensitivity Level: MSL 1 (Unlimited) preferred for handling consistency

The three substitute parts listed below meet these criteria with varying electrical characteristics and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

MA4E2200D1-287T (MACOM Technology Solutions)

This substitute is active in production with MSL 1 rating and enhanced operating temperature of 175°C (TJ). The 1.5V peak reverse voltage rating is lower than the main part; applications requiring 2V operation must verify margin requirements. Capacitance specification of 0.25pF @ 150mV, 1MHz is tighter than the main part, supporting improved RF performance in certain circuit topologies. Power dissipation rating of 75 mW provides thermal headroom.

SBX201C-TB-E (onsemi)

This substitute maintains the 2V peak reverse voltage rating and 150°C (TJ) operating temperature matching the main part specifications. Product status is obsolete, similar to the main part. Capacitance of 0.28pF @ 0V, 1MHz is comparable to the main part. Current rating of 50 mA is specified. RoHS3 compliance and REACH unaffected status are documented.

SMS7630-005LF (Skyworks Solutions Inc.)

This substitute is active in production with RoHS3 compliance and REACH unaffected status. Operating temperature range of -65°C ~ 150°C (TA) provides extended low-temperature performance. The 1V peak reverse voltage rating is significantly lower than the main part; applications must confirm voltage margin requirements. Power dissipation of 75 mW and current rating of 50 mA are specified. Capacitance specification is not provided.

Frequently Asked Questions (FAQ)

Q: Can MA4E2200D1-287T replace HSMS-2852-TR1G in all applications?

A: MA4E2200D1-287T has a 1.5V peak reverse voltage rating compared to the main part's 2V rating. Substitution is valid only for applications where the circuit voltage stress does not exceed 1.5V. Verify your circuit's maximum reverse voltage requirement before selection.

Q: What is the primary difference between SBX201C-TB-E and SMS7630-005LF?

A: SBX201C-TB-E maintains the 2V peak reverse voltage rating of the main part, while SMS7630-005LF is rated for 1V. SBX201C-TB-E is obsolete; SMS7630-005LF is active in production. For new designs, SMS7630-005LF is preferred if voltage requirements permit 1V operation.

Q: Are all substitute parts in the same physical package?

A: Yes. All substitute parts use TO-236-3, SC-59, SOT-23-3 packaging, ensuring mechanical and electrical compatibility with the main part's footprint and pinout.

Q: Which substitute has the best thermal performance?

A: MA4E2200D1-287T has the highest operating temperature rating at 175°C (TJ), providing 25°C additional thermal margin compared to the main part and SBX201C-TB-E at 150°C (TJ).

Q: Are there compliance or regulatory differences between substitutes?

A: SBX201C-TB-E and SMS7630-005LF both carry RoHS3 compliance and REACH unaffected status. MA4E2200D1-287T compliance documentation is not specified in the provided data. Verify compliance requirements for your application before final selection.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level, meaning these components can be stored indefinitely without moisture bake-out requirements prior to soldering, simplifying inventory and manufacturing logistics.
