Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH5512-TL-E is determined by the following critical electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 50V minimum required
• Current - Max: 50 mA minimum required
• Capacitance @ Vr, F: 0.23pF or lower preferred for RF performance
• Resistance @ If, F: 5Ohm or lower preferred for minimal insertion loss
• Operating Temperature: 125°C (TJ) minimum
• Package compatibility: Physical form factor and pin configuration

The 1SV263-TL-E qualifies as a substitute based on matching voltage and current ratings. However, structural differences exist: the CPH5512-TL-E contains 2 independent PIN diodes, while the 1SV263-TL-E is a single PIN diode configuration. This distinction affects circuit integration and layout considerations.

Parameter Comparison

Engineering Selection Recommendations

Both the CPH5512-TL-E and 1SV263-TL-E are classified as obsolete products. Selection between these parts depends on circuit requirements:

The CPH5512-TL-E provides dual independent PIN diode functionality within a single package, suitable for applications requiring two isolated switching or attenuating elements. The 1SV263-TL-E offers a single PIN diode with lower capacitance (0.4pF vs. 0.23pF) and slightly lower resistance (4.5Ohm vs. 5Ohm), providing marginal RF performance advantages in single-diode applications.

Both parts maintain identical voltage and current ratings (50V, 50 mA), identical operating temperature limits (125°C TJ), and equivalent compliance status (REACH Unaffected, EAR99 classification). Package differences (SC-74A/SOT-753 vs. SC-70/SOT-323) require layout and PCB footprint evaluation.

Frequently Asked Questions (FAQ)

Q: Can the 1SV263-TL-E directly replace the CPH5512-TL-E in all applications?

A: Direct replacement is not universal. The CPH5512-TL-E contains 2 independent diodes; the 1SV263-TL-E contains 1 diode. Applications requiring dual diode functionality cannot use the 1SV263-TL-E as a single-component substitute. Dual 1SV263-TL-E devices may be required, with corresponding layout and cost implications.

Q: What are the key electrical differences between these parts?

A: Both parts share identical voltage (50V) and current (50 mA) ratings. The 1SV263-TL-E exhibits lower capacitance (0.4pF vs. 0.23pF) and marginally lower resistance (4.5Ohm vs. 5Ohm). These differences are minor and do not affect functional compatibility in most RF switching applications.

Q: Are package differences significant for substitution?

A: Yes. The CPH5512-TL-E uses SC-74A/SOT-753 packaging; the 1SV263-TL-E uses SC-70/SOT-323 packaging. These are physically distinct packages requiring different PCB footprints. Mechanical compatibility must be verified before substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are REACH Unaffected, classified as EAR99, and maintain MSL 1 (Unlimited) moisture sensitivity ratings. Compliance status is equivalent.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these parts are no longer in active production. Inventory availability is limited. Long-term design strategies should evaluate current-generation RF PIN diode alternatives from onsemi or other manufacturers.
