Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMP-3890-TR2G is determined by the following critical parameters: diode type (PIN - Single), peak reverse voltage rating, maximum current capacity, and package compatibility. Substitute parts must maintain functional equivalence within the electrical operating envelope defined by these specifications.

The two identified substitute parts represent different substitution scenarios:

1SV263-TL-E provides a lower-voltage alternative (50V peak reverse) with reduced current capacity (50mA maximum) and lower power dissipation (100mW). This substitute is suitable for applications where the full voltage and current ratings of the original part are not required.

MA4P7441F-1091T maintains the 100V peak reverse voltage rating of the original part while offering enhanced current capacity (500mA) and significantly higher power dissipation capability (30W). This substitute is suitable for applications requiring higher power handling or current delivery within the same voltage class.

Parameter Comparison

Engineering Selection Recommendations

MA4P7441F-1091T is the preferred substitute for new designs and ongoing procurement. This part maintains the 100V peak reverse voltage specification of the original HSMP-3890-TR2G, ensuring compatibility with circuits designed for this voltage class. The MA4P7441F-1091T carries Active product status, confirming current manufacturing availability and long-term supply continuity. RoHS3 compliance and unlimited moisture sensitivity rating align with modern manufacturing standards.

1SV263-TL-E is suitable only for applications where the circuit design permits operation at reduced voltage (50V) and current (50mA) ratings. This part is classified as obsolete, presenting potential future supply constraints. Selection of this substitute requires verification that the lower electrical ratings do not compromise circuit performance or safety margins.

Both substitute parts maintain the MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture-related handling requirement changes from the original specification.

Frequently Asked Questions (FAQ)

Q: Can 1SV263-TL-E directly replace HSMP-3890-TR2G in all applications?

A: No. The 1SV263-TL-E operates at a maximum peak reverse voltage of 50V, compared to the HSMP-3890-TR2G specification of 100V. Direct substitution is only valid in circuits where the applied reverse voltage does not exceed 50V. The maximum current rating of 50mA is also significantly lower than the original 1A specification.

Q: What are the package differences between the substitute parts?

A: The HSMP-3890-TR2G uses a SOT-23-3 package. The 1SV263-TL-E uses SC-70 or SOT-323 packaging, which are physically different and require PCB layout modifications. The MA4P7441F-1091T uses 2-SMD packaging, also requiring layout changes. Package substitution necessitates PCB redesign and re-qualification.

Q: Why is MA4P7441F-1091T recommended over 1SV263-TL-E?

A: MA4P7441F-1091T maintains the 100V peak reverse voltage rating of the original part, ensuring compatibility with existing circuit designs without voltage derating. Additionally, MA4P7441F-1091T carries Active product status, guaranteeing current manufacturing and long-term availability, whereas 1SV263-TL-E is classified as obsolete.

Q: Are there operating temperature considerations when substituting?

A: The HSMP-3890-TR2G operates to 150°C (TJ). The 1SV263-TL-E is rated to 125°C (TJ), representing a 25°C reduction in maximum junction temperature. The MA4P7441F-1091T is rated to 175°C (TJ), providing a 25°C increase. Temperature derating must be evaluated against circuit thermal design requirements.

Q: Do the substitute parts have different compliance certifications?

A: All three parts carry REACH Unaffected status and EAR99 ECCN classification. The MA4P7441F-1091T and 1SV263-TL-E both carry RoHS3 compliance certification. The HSMP-3890-TR2G RoHS status is not specified in the provided data. Compliance verification against specific procurement requirements is necessary.
