Electrical Parameters Match:
- Frequency: 20 MHz (identical)
- Output: HCMOS (identical)
- Supply Voltage: 3.3V (identical)
- Function: Enable/Disable (identical)
- Frequency Stability: ±100ppm (identical)
- Operating Temperature: -10°C ~ 70°C (identical)
- Supply Current (Max): 15mA (identical)
- Disable Current (Max): 10µA (identical)
Mechanical Parameters Match:
- Package: 4-SMD, No Lead (identical)
- Dimensions: 7.50mm x 5.20mm x 1.50mm (identical)
Compliance Parameters Match:
- RoHS Status: ROHS3 Compliant (identical)

Engineering Selection Recommendations
The FO7HSCAE20.0-T1 is the direct substitute for the obsolete FO7HSCAE20.0-T2. Selection of the substitute is justified by:
- Product Status: The FO7HSCAE20.0-T1 maintains Active status, ensuring long-term availability and supply chain continuity.
- Electrical Equivalence: All electrical parameters, including frequency, output type, supply voltage, current consumption, and frequency stability, are identical.
- Mechanical Compatibility: Package type, dimensions, and mounting configuration are identical, enabling direct PCB-level substitution without layout modifications.
- Compliance Alignment: Both parts maintain identical RoHS3 compliance, moisture sensitivity ratings, and export classifications.
- Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for production environments and does not affect component functionality or performance.
Frequently Asked Questions (FAQ)
Q: Can FO7HSCAE20.0-T1 be used as a direct replacement for FO7HSCAE20.0-T2 on existing PCBs?
A: Yes. The parts are electrically and mechanically identical. All electrical parameters, package dimensions, and pin configurations match exactly. No PCB modifications are required.
Q: What is the difference between the main part and the substitute?
A: The primary differences are product status (Obsolete vs. Active) and packaging format (standard vs. Tape & Reel). Functionally and electrically, the parts are equivalent.
Q: Does the Tape & Reel packaging affect component performance?
A: No. Tape & Reel is a standard production packaging format that does not affect electrical performance, reliability, or functionality. It is the industry standard for automated assembly processes.
Q: Are there any compliance or certification differences?
A: No. Both parts maintain identical RoHS3 compliance, moisture sensitivity levels, ECCN classifications, and HTSUS codes.
Q: What is the frequency stability specification, and does it apply to both parts?
A: Both parts specify ±100ppm frequency stability across the operating temperature range of -10°C to 70°C. This specification is identical for both the main part and substitute.
Q: Can these parts be used interchangeably in new designs?
A: Yes. The FO7HSCAE20.0-T1 is recommended for new designs due to its Active product status, ensuring long-term availability and supply chain support.
