Key Parameters

Substitute Part Grouping Explanation

The 1SV264-TL-E qualifies as a direct substitute based on the following criteria:

• Identical voltage rating: 50V peak reverse voltage
• Identical current rating: 50 mA maximum
• Identical capacitance specification: 0.4pF @ 50V, 1MHz
• Identical resistance specification: 4.5Ohm @ 10mA, 100MHz
• Identical power dissipation: 100 mW
• Identical operating temperature: 125°C (TJ)
• Identical package: SC-70, SOT-323
• Identical RoHS and MSL compliance

The primary distinction is the diode configuration: the 1SV263-TL-E is a PIN - Single configuration, while the 1SV264-TL-E is a PIN - 1 Pair Series Connection configuration. This structural difference does not affect the core electrical parameters that determine substitutability for equivalent performance applications.

Engineering Selection Recommendations

The 1SV264-TL-E is the designated substitute for the obsolete 1SV263-TL-E. Selection of the 1SV264-TL-E provides the following advantages:

• Active product status ensures continued availability and manufacturing support
• Full compliance with ROHS3 and REACH requirements
• Identical electrical performance across all specified parameters
• Equivalent MSL rating for moisture-sensitive device handling
• Same package footprint (SC-70, SOT-323) for direct PCB compatibility

For applications currently using the 1SV263-TL-E, transition to the 1SV264-TL-E maintains electrical equivalence while securing long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 1SV264-TL-E directly replace the 1SV263-TL-E in existing designs?

A: Yes. Both parts share identical electrical specifications including voltage, current, capacitance, resistance, and power dissipation ratings. The package footprint is identical (SC-70, SOT-323), enabling direct PCB substitution.

Q: What is the difference between PIN - Single and PIN - 1 Pair Series Connection configurations?

A: The 1SV263-TL-E contains a single PIN diode element, while the 1SV264-TL-E contains two PIN diode elements connected in series. Despite this structural difference, both maintain the same electrical performance specifications for the parameters listed.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical MSL ratings of 1 (Unlimited). Compliance certifications are equivalent.

Q: Why is the 1SV263-TL-E classified as Obsolete?

A: The 1SV263-TL-E has reached end-of-life status. The 1SV264-TL-E is the active equivalent maintained by onsemi for continued production and supply.

Q: What packaging formats are available for the 1SV264-TL-E?

A: The 1SV264-TL-E is supplied in Cut Tape (CT) and Digi-Reel® packaging, compared to the Tape & Reel (TR) format of the obsolete 1SV263-TL-E.
