1SV246-TL-E Equivalent & Substitute Parts

Part Overview

The 1SV246-TL-E is an RF Diode PIN manufactured by onsemi, designed for 50V peak reverse voltage applications with 100 mW power dissipation. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates as a 1 Pair Series Connection PIN diode suitable for RF switching and attenuation applications in SC-70 / SOT-323 packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1SV246-TL-E is determined by strict electrical and mechanical compatibility across the following parameters:

• Diode Type: PIN - 1 Pair Series Connection (mandatory match)
• Voltage - Peak Reverse (Max): 50V (mandatory match)
• Current - Max: 50 mA (mandatory match)
• Power Dissipation (Max): 100 mW (mandatory match)
• Package / Case: SC-70, SOT-323 (mandatory match)
• Capacitance @ Vr, F: 0.23pF or higher acceptable at rated voltage
• Resistance @ If, F: Variations within RF performance tolerance acceptable
• Operating Temperature: Minimum 125°C (TJ) required
• Moisture Sensitivity Level (MSL): 1 (Unlimited) required

Three substitute parts meet these criteria and are grouped as follows:

Direct Manufacturer Substitute: NSVP249SDSF3T1G (onsemi) - Active product status with automotive qualification

Parametric Equivalents: 1SV264-TL-E (onsemi) and RN739FT106 (Rohm Semiconductor) - Active products with minor parameter variations within acceptable RF performance ranges

Parameter Comparison

Engineering Selection Recommendations

NSVP249SDSF3T1G is the primary substitute for new designs. This part maintains identical electrical specifications to the 1SV246-TL-E while offering active product status, extended operating temperature range (-55°C ~ 125°C), and AEC-Q101 automotive qualification. ROHS3 compliance and Tape & Reel packaging support high-volume production requirements.

1SV264-TL-E serves as a secondary substitute within the onsemi product family. Electrical parameters remain compatible with minor capacitance variation (0.4pF vs. 0.23pF). Active product status and ROHS3 compliance ensure supply continuity. Cut Tape & Digi-Reel packaging accommodates both prototype and production volumes.

RN739FT106 provides cross-manufacturer substitution from Rohm Semiconductor. This part maintains all critical electrical parameters with acceptable resistance variation (7Ohm vs. 5Ohm). Active product status and ROHS3 compliance support long-term availability. Selection of this part requires verification of supplier device package compatibility (UMD3) with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can NSVP249SDSF3T1G directly replace 1SV246-TL-E in existing designs?

A: Yes. NSVP249SDSF3T1G maintains identical electrical specifications (50V, 50 mA, 100 mW, 0.23pF capacitance, 4.5Ohm resistance) and SC-70 / SOT-323 packaging. The extended operating temperature range (-55°C ~ 125°C) and automotive qualification provide enhanced reliability margins.

Q: What is the difference between the three substitute parts?

A: NSVP249SDSF3T1G is the direct manufacturer substitute with identical capacitance specification. 1SV264-TL-E and RN739FT106 are parametric equivalents with slightly higher capacitance (0.4pF) and varying resistance characteristics, acceptable for RF applications within the specified voltage and current ranges.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. NSVP249SDSF3T1G, 1SV264-TL-E, and RN739FT106 are all ROHS3 compliant. The original 1SV246-TL-E RoHS status is not specified due to its obsolete classification.

Q: Does packaging differ between substitute parts?

A: NSVP249SDSF3T1G is supplied in Tape & Reel (TR) packaging. 1SV264-TL-E is supplied in Cut Tape (CT) & Digi-Reel packaging. RN739FT106 is supplied in Tape & Reel (TR) packaging. All three maintain SC-70 / SOT-323 physical form factor compatibility.

Q: What is the operating temperature range for each substitute?

A: NSVP249SDSF3T1G operates from -55°C to 125°C (TJ). Both 1SV264-TL-E and RN739FT106 operate to 125°C (TJ) maximum. Selection depends on application temperature requirements.

Q: Is RN739FT106 from a different manufacturer compatible?

A: Yes. RN739FT106 from Rohm Semiconductor meets all mandatory electrical and mechanical parameters. Cross-manufacturer substitution is valid provided the UMD3 supplier device package is compatible with existing PCB layouts and assembly processes.
