Parameter Comparison

Engineering Selection Recommendations

All three oscillators listed are Active products with full RoHS3 compliance, supporting unrestricted use in regulated applications. Selection between the PDF620008Z, JX5021E0156.250000, and SXO53P3A481-156.250M is determined by supply availability, packaging preference, and power consumption requirements within the design envelope.

The JX5021E0156.250000 offers reduced maximum supply current (60mA versus 80mA) and lower disable-mode current (20mA), making it suitable for power-constrained applications. The SXO53P3A481-156.250M provides the lowest seated height (1.20mm) for space-constrained PCB layouts and is available in bulk packaging.

All parts maintain identical electrical performance across frequency, output type, supply voltage, function, frequency stability, and operating temperature specifications. Mechanical compatibility is confirmed across all three devices within the 6-SMD, No Lead package format.

Frequently Asked Questions (FAQ)

Q: Can the JX5021E0156.250000 be used as a direct replacement for the PDF620008Z?

A: Yes. Both devices share identical electrical specifications (156.25 MHz, LVPECL, 3.3V, ±50ppm stability, -40°C to 85°C operation) and mechanical compatibility (6-SMD, No Lead, 5.00mm × 3.20mm). The JX5021E0156.250000 operates at lower maximum supply current (60mA) and disable-mode current (20mA), which may provide power efficiency benefits in applications where these parameters are monitored.

Q: Is the SXO53P3A481-156.250M compatible with PDF620008Z designs?

A: Yes. The SXO53P3A481-156.250M meets all electrical and mechanical requirements for substitution. The device is 0.15mm shorter in seated height (1.20mm versus 1.35mm), which may be advantageous in height-constrained assemblies. Bulk packaging differs from the tape & reel format of the PDF620008Z, affecting procurement and handling procedures.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of frequency (156.25 MHz), output type (LVPECL), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C to 85°C), package type (6-SMD, No Lead), and package dimensions (5.00mm × 3.20mm). All listed substitutes meet these criteria.

Q: Are there differences in current consumption between these oscillators?

A: Yes. The PDF620008Z and SXO53P3A481-156.250M specify 80mA maximum supply current, while the JX5021E0156.250000 specifies 60mA. In disable mode, the PDF620008Z draws 30µA maximum, the JX5021E0156.250000 draws 20mA, and the SXO53P3A481-156.250M does not specify this parameter. These differences should be evaluated against power budget requirements.

Q: Do all parts carry the same regulatory certifications?

A: All three oscillators are RoHS3 compliant and Active products. The PDF620008Z and JX5021E0156.250000 specify MSL 1 (Unlimited) moisture sensitivity rating. The SXO53P3A481-156.250M does not specify MSL rating in the provided data.
