Key Parameters

Substitute Part Grouping Explanation

The 9211D-3M-SMA antenna qualifies for substitution with the 9211D model based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Frequency (Center/Band): 1.621GHz
• Frequency Range: 1.616GHz ~ 1.6265GHz
• Antenna Type: Module
• Number of Bands: 1
• Gain: 4dBic
• VSWR: 2
• Termination: SMA
• Mounting Type: Magnetic
• Ingress Protection: IP67
• Height (Max): 0.535" (13.60mm)
• RF Family/Standard: Navigation
• Frequency Group: UHF (1GHz ~ 2GHz)
• Applications: GNSS

The 9211D represents the active production equivalent of the obsolete 9211D-3M-SMA. Both parts maintain identical electrical performance characteristics across all RF parameters and mechanical specifications. The primary difference is the cable length: the 9211D-3M-SMA includes a 3-meter cable assembly with integrated LNA and filter, while the 9211D includes a 2-meter cable assembly.

Parameter Comparison

Engineering Selection Recommendations

The 9211D serves as the direct active equivalent for the obsolete 9211D-3M-SMA. Both parts are manufactured by PCTEL, Inc. and share identical RF performance specifications, mechanical dimensions, and environmental ratings. The 9211D is the recommended substitute for new designs and field replacements where the 9211D-3M-SMA is no longer available.

Selection between these parts depends on cable length requirements. The 9211D-3M-SMA provides a 3-meter cable assembly with integrated LNA and filter, while the 9211D provides a 2-meter cable assembly. System integration requirements and installation geometry determine which cable length is appropriate for the application.

Both parts carry identical export control classifications (ECCN 7A994) and tariff codes (HTSUS 8529.10.4040), ensuring compliance consistency across procurement and supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the 9211D directly replace the 9211D-3M-SMA in existing systems?

A: The 9211D is electrically and mechanically equivalent to the 9211D-3M-SMA across all RF parameters and physical specifications. The primary consideration is cable length: the 9211D provides 2 meters of cable versus the 3 meters supplied with the 9211D-3M-SMA. System installation geometry and cable routing requirements determine compatibility.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on matching frequency (1.621GHz center, 1.616GHz ~ 1.6265GHz range), antenna type (module), gain (4dBic), VSWR (2), termination (SMA), and RF family (Navigation). Both parts meet these criteria identically.

Q: Are there differences in the integrated components?

A: The 9211D-3M-SMA includes integrated LNA and filter components within the 3-meter cable assembly. The 9211D provides a 2-meter cable assembly. Verify that system designs do not depend on the specific LNA and filter characteristics of the 9211D-3M-SMA before substitution.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 9211D is in active production status, ensuring continued availability, supply chain support, and manufacturer technical support. The 9211D-3M-SMA is obsolete and no longer manufactured, making the 9211D the appropriate long-term component choice.

Q: Are the environmental ratings identical?

A: Both parts carry IP67 ingress protection rating and identical mechanical dimensions (0.535" maximum height). Environmental performance is equivalent across both parts.

Q: Do export control classifications differ between these parts?

A: Both parts carry identical ECCN (7A994) and HTSUS (8529.10.4040) classifications, ensuring consistent compliance documentation and export control treatment.
