1SV246-TL-EX Equivalent & Substitute Parts

Part Overview

The 1SV246-TL-EX is an RF Diode PIN manufactured by onsemi, configured as a 1 Pair Series Connection with a peak reverse voltage rating of 50V and maximum power dissipation of 100 mW. This component is classified as Obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges to ensure functional equivalence in RF switching and attenuation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1SV246-TL-EX is determined by strict equivalence across the following critical parameters:

• Diode Configuration: PIN - 1 Pair Series Connection (functional topology must match)
• Voltage Rating: Peak reverse voltage of 50V (minimum requirement)
• Current Capacity: Maximum forward current of 50 mA
• Power Dissipation: 100 mW maximum rating
• Package Type: SC-70 or SOT-323 (mechanical and thermal compatibility)
• Operating Temperature: 125°C junction temperature capability
• Moisture Sensitivity: MSL 1 classification

The identified substitute parts—1SV264-TL-E (onsemi) and RN739FT106 (Rohm Semiconductor)—satisfy all mandatory electrical and mechanical parameters. Both parts are Active status components with current manufacturing availability, providing direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

1SV264-TL-E (onsemi) is the primary substitute option. This part maintains identical electrical specifications to the 1SV246-TL-EX while offering Active product status with current manufacturing support. The 1SV264-TL-E is ROHS3 compliant and available in Cut Tape and Digi-Reel packaging formats, supporting both prototype and production procurement workflows. Inventory availability is 1510 units.

RN739FT106 (Rohm Semiconductor) serves as a secondary cross-manufacturer substitute. This part meets all mandatory electrical and mechanical requirements with Active status and ROHS3 compliance. The RN739FT106 is supplied in Tape & Reel format with 3300 units in stock. Minor variations in capacitance measurement conditions (0.4pF @ 35V versus 50V) and series resistance (7Ohm versus 5Ohm) remain within acceptable tolerance ranges for RF PIN diode applications.

Selection between these substitutes should be based on procurement channel availability, packaging format requirements, and supply chain preferences. Both parts provide equivalent functional performance for direct replacement of the obsolete 1SV246-TL-EX.

Frequently Asked Questions (FAQ)

Q: Can the 1SV264-TL-E directly replace the 1SV246-TL-EX in existing designs?

A: Yes. The 1SV264-TL-E maintains identical electrical ratings (50V peak reverse voltage, 50 mA maximum current, 100 mW power dissipation) and package configuration (SC-70, SOT-323). Both parts are PIN diodes with 1 Pair Series Connection topology. The substitute is pin-compatible and functionally equivalent.

Q: What are the differences between the 1SV264-TL-E and RN739FT106?

A: Both parts meet the core electrical requirements. The 1SV264-TL-E is manufactured by onsemi (same as the original part) with capacitance of 0.4pF @ 50V and series resistance of 4.5Ohm. The RN739FT106 is manufactured by Rohm Semiconductor with capacitance of 0.4pF @ 35V and series resistance of 7Ohm. These minor parameter variations do not affect functional equivalence for standard RF switching applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1SV264-TL-E and RN739FT106 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for these substitutes?

A: The 1SV264-TL-E is available in Cut Tape (CT) and Digi-Reel formats. The RN739FT106 is supplied in Tape & Reel format. Both support standard automated assembly processes.

Q: Is the MSL rating identical across all three parts?

A: Yes. The 1SV246-TL-EX, 1SV264-TL-E, and RN739FT106 all carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
