Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UX72F6214Z are qualified based on the following criteria:

• Identical frequency: 156.25 MHz
• Matching output type: LVPECL
• Identical supply voltage: 3.3V
• Matching function: Enable/Disable capability
• Identical frequency stability: ±50ppm
• Matching operating temperature range: -40°C ~ 85°C
• Compatible package: 6-SMD, No Lead surface mount
• Matching package dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Compliance: ROHS3 compliant, REACH unaffected

All substitute parts meet these core electrical and mechanical parameters, ensuring functional and physical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four oscillators meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

Supply Current Considerations: The PB223-156.25M (Connor Winfield) offers the lowest maximum supply current at 50mA, followed by the SG7050EEN (EPSON) at 60mA and SXO75P3A481-156.250M (Suntsu) at 80mA. The UX72F6214Z (Diodes) draws 85mA maximum. Applications with strict power budget constraints may prioritize lower current consumption.

Physical Height: The PB223-156.25M has the lowest seated height at 0.058" (1.47mm), while the SG7050EEN and SXO75P3A481-156.250M both measure 0.067" (1.70mm). The UX72F6214Z measures 0.061" (1.55mm). Height differences are minimal and should not restrict substitution in most PCB layouts.

Compliance and Certifications: All parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and telecommunications applications. The UX72F6214Z, PB223-156.25M, and SG7050EEN explicitly specify MSL 1 (Unlimited) moisture sensitivity, indicating superior moisture resistance.

Packaging Format: The UX72F6214Z and substitute parts from Connor Winfield and EPSON are supplied in Tape & Reel (TR) format, suitable for automated assembly. The SXO75P3A481-156.250M is supplied in Bulk format, which may require manual handling or reeling for automated processes.

Frequently Asked Questions (FAQ)

Q: Can the PB223-156.25M directly replace the UX72F6214Z?

A: Yes. Both parts share identical electrical specifications (156.25 MHz, LVPECL, 3.3V, ±50ppm stability, Enable/Disable function) and mechanical compatibility (6-SMD, No Lead, 7.00mm x 5.00mm). The PB223-156.25M operates at lower maximum supply current (50mA vs. 85mA) and has a lower seated height (1.47mm vs. 1.55mm), making it suitable for power-constrained or space-limited applications.

Q: What are the differences between the EPSON SG7050EEN and the Diodes UX72F6214Z?

A: Both oscillators meet all core electrical and mechanical specifications. The SG7050EEN has a maximum supply current of 60mA compared to 85mA for the UX72F6214Z, and a slightly higher seated height of 0.067" (1.70mm) versus 0.061" (1.55mm). The SG7050EEN specifies a disable current of 25mA, providing additional power management data.

Q: Is the Suntsu SXO75P3A481-156.250M compatible with the UX72F6214Z?

A: Yes. The SXO75P3A481-156.250M meets all electrical and mechanical requirements for substitution. It operates at 80mA maximum supply current and has a seated height of 0.067" (1.70mm). The primary difference is packaging format: Suntsu supplies this part in Bulk format rather than Tape & Reel, which may affect assembly process compatibility.

Q: Are there any thermal or environmental limitations when substituting these parts?

A: All substitute parts operate across the identical temperature range of -40°C to 85°C. The UX72F6214Z, PB223-156.25M, and SG7050EEN all specify MSL 1 (Unlimited) moisture sensitivity, indicating no moisture-related handling restrictions. The SXO75P3A481-156.250M does not specify MSL rating in the provided data.

Q: Which substitute part offers the best power efficiency?

A: The PB223-156.25M (Connor Winfield) provides the lowest maximum supply current at 50mA, representing approximately 41% lower power consumption compared to the UX72F6214Z at 85mA. For applications requiring extended battery life or thermal management, this part is the optimal choice.

Q: Can these oscillators be used interchangeably in automated assembly?

A: The UX72F6214Z, PB223-156.25M, and SG7050EEN are all supplied in Tape & Reel format, enabling direct use in automated pick-and-place assembly. The SXO75P3A481-156.250M is supplied in Bulk format and requires manual reeling or alternative handling procedures for automated processes.
