7X-50.000MBA-T CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The 7X-50.000MBA-T is a 50 MHz XO (Standard) CMOS oscillator manufactured by TXC CORPORATION. This surface mount crystal oscillator operates at 3.3V with Enable/Disable functionality, housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm. The device is Active product status and RoHS Compliant, suitable for applications requiring stable 50 MHz frequency generation with low power consumption.

Substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the 7X-50.000MBA-T are qualified based on the following critical parameters:

Electrical Compatibility:

• Frequency: 50 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -10°C ~ 70°C (exact match required)

Mechanical Compatibility:

• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 3.20mm x 2.50mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance & Status:

• Product Status: Active
• RoHS Compliance: Required

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Current consumption and seated height variations within manufacturer specifications do not affect functional substitution.

Engineering Selection Recommendations

Primary Part: 7X-50.000MBA-T

The TXC CORPORATION 7X-50.000MBA-T is the original specification part. Selection is appropriate when:

• TXC supply chain is preferred
• Tape & Reel packaging is required
• Existing design validation is based on this manufacturer

Substitute Part: SXO32C3C171-50.000M

The Suntsu Electronics SXO32C3C171-50.000M is electrically and mechanically equivalent. Selection is appropriate when:

• TXC supply is unavailable or lead times exceed project requirements
• Bulk packaging is acceptable for manufacturing processes
• Suntsu supply chain offers cost or availability advantages
• Design flexibility permits manufacturer substitution

Both parts are Active product status and meet RoHS compliance requirements. The substitute part demonstrates lower maximum supply current (17mA vs 20mA), which may provide marginal power consumption benefits. Seated height difference (1.20mm vs 1.10mm) is within typical PCB assembly tolerances and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can SXO32C3C171-50.000M be used as a direct replacement for 7X-50.000MBA-T?

A: Yes. Both parts meet identical electrical specifications (50 MHz, CMOS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -10°C to 70°C operating range) and mechanical requirements (4-SMD No Lead package, 3.20mm x 2.50mm dimensions, surface mount). Substitution is valid for PCB assembly and functional operation.

Q: What are the differences between these parts?

A: Differences are limited to non-critical parameters: manufacturer (TXC vs Suntsu), series designation (7X vs SXO32C), packaging format (Tape & Reel vs Bulk), maximum supply current (20mA vs 17mA), and seated height (1.10mm vs 1.20mm). These differences do not affect electrical performance or circuit compatibility.

Q: Does packaging format affect substitution?

A: Packaging format (Tape & Reel vs Bulk) affects manufacturing logistics and handling but not electrical or mechanical compatibility. Both formats contain identical components. Selection depends on manufacturing process requirements and inventory management practices.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The substitute part carries ROHS3 certification while the primary part carries standard RoHS certification. Both meet regulatory requirements for the specified application.

Q: What is the maximum seated height difference impact?

A: The seated height difference (1.10mm primary vs 1.20mm substitute) is 0.10mm. This variation is within standard PCB assembly tolerances and does not affect component placement, solder joint formation, or circuit board clearance in typical designs.

Q: Can I mix these parts in the same production run?

A: Yes. Both parts are electrically and mechanically equivalent. Mixed sourcing is permissible when supply constraints require it. Ensure PCB assembly documentation reflects both acceptable part numbers to prevent assembly errors.
