Mandatory Matching Parameters:

• Circuit topology: SPDT configuration
• Package type: 16-VFQFN Exposed Pad (16-QFN 3x3)
• Mounting type: Surface Mount
• Impedance: 50Ohm
• Frequency range: 500MHz ~ 5GHz minimum coverage
• Supply voltage range: 2.6V ~ 5.5V compatibility
• Operating temperature range: -40°C ~ 85°C minimum
• RoHS3 compliance status

Performance Parameters Evaluated:

• Isolation (minimum 21dB acceptable)
• Insertion loss (maximum 0.45dB acceptable)
• P1dB linearity (where specified)
• IIP3 third-order intercept point (minimum 70dBm)

The TS8329K meets all mandatory matching criteria and operates within acceptable performance tolerances for direct substitution in existing TS7329K applications.

Parameter Comparison

Engineering Selection Recommendations

TS8329K as Primary Substitute:

The TS8329K is the direct equivalent part for TS7329K applications. Both components share identical package geometry, electrical interface specifications, and operating ranges. The TS8329K carries an "Active" product status, indicating ongoing manufacturer support and continued availability.

Compliance and Certification Alignment:

Both the TS7329K and TS8329K maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited). Both components are classified under ECCN EAR99 and HTSUS 8542.39.0001, ensuring regulatory consistency for supply chain and export documentation purposes.

Performance Considerations:

The TS8329K exhibits measurable differences in isolation (21dB versus 30dB) and insertion loss (0.45dB versus 0.4dB). These differences are within typical manufacturing tolerances for RF switch components and do not preclude functional substitution in cellular and LTE applications. The TS8329K demonstrates superior third-order intercept performance (71dBm versus 70dBm).

Supply Chain Status:

The TS7329K "Not For New Designs" designation combined with the TS8329K "Active" status establishes the TS8329K as the recommended path for design continuity and long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the TS8329K be used as a direct replacement for the TS7329K in existing PCB assemblies?

A: Yes. Both components utilize identical 16-VFQFN Exposed Pad packages with matching pin configurations, supply voltage ranges (-40°C to 85°C operating temperature), and 50-ohm impedance specifications. No PCB layout modifications are required.

Q: What are the performance trade-offs when substituting TS8329K for TS7329K?

A: The TS8329K provides 9dB lower isolation (21dB versus 30dB) and 0.05dB higher insertion loss (0.45dB versus 0.4dB). The TS8329K delivers 1dBm higher IIP3 performance (71dBm versus 70dBm). These differences fall within acceptable operating margins for cellular and LTE RF switch applications.

Q: Are there any compliance or regulatory differences between these parts?
