Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SQ2303P12NF are identified based on strict electrical and mechanical parameter matching within the RF antenna product category. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Frequency Group: UHF (2GHz ~ 3GHz)
• Center Frequency: 2.4GHz
• Frequency Range: 2.4GHz ~ 2.5GHz
• Gain: 3.5dBi
• VSWR: 1.5
• Termination Type: N Type Female

Mechanical Parameters:

• Antenna Type: Panel
• Mounting Type: Chassis Mount
• Cable Length: 305mm
• Number of Bands: 1

Compliance Parameters:

• Manufacturer: TE Connectivity Laird
• Series: Squint™
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: 5A991G

Substitute parts must match all electrical parameters, maintain mechanical compatibility with chassis mount configuration and N Type Female termination, and originate from the same manufacturer series to ensure functional equivalence and design compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SQ2403PG12NF is a direct electrical and mechanical substitute for the obsolete SQ2303P12NF. Both components share identical electrical performance specifications including frequency range (2.4GHz ~ 2.5GHz), gain (3.5dBi), VSWR (1.5), and termination type (N Type Female). Both maintain the same panel antenna configuration with chassis mount installation and 305mm cable length.

The SQ2403PG12NF carries Active product status, ensuring ongoing manufacturer support and supply chain availability. The substitute part is RoHS Compliant, providing enhanced environmental compliance compared to the obsolete original part.

The primary mechanical difference is the reduced maximum height of the SQ2403PG12NF (0.866" / 22.00mm) compared to the SQ2303P12NF (1.250" / 31.75mm). This dimensional reduction must be evaluated against available mounting space in the target application. Both parts maintain identical electrical performance and are suitable for direct substitution in 2.4GHz panel antenna applications requiring N Type Female chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the SQ2403PG12NF directly replace the SQ2303P12NF in existing designs?

A: The SQ2403PG12NF provides electrical equivalence with identical frequency range, gain, VSWR, and termination specifications. The primary consideration is the reduced physical height (22.00mm versus 31.75mm). Verify available mounting space in your chassis design before implementation.

Q: What is the significance of the product status difference between these parts?

A: The SQ2303P12NF is classified as Obsolete, indicating discontinued manufacturing and limited long-term availability. The SQ2403PG12NF maintains Active status, ensuring continued manufacturer support, documented supply chain availability, and ongoing technical support.

Q: Are there compliance differences between the two parts?

A: The SQ2403PG12NF is RoHS Compliant, meeting environmental and hazardous substance restrictions. Both parts share identical ECCN (5A991G) export control classification and MSL rating (1 - Unlimited).

Q: What parameters must remain identical for substitution compatibility?

A: Electrical parameters including frequency range (2.4GHz ~ 2.5GHz), gain (3.5dBi), VSWR (1.5), and termination type (N Type Female) must match. Mechanical parameters including antenna type (Panel), mounting type (Chassis Mount), and cable length (305mm) must also remain identical.

Q: How does the height difference affect antenna performance?

A: The height specification relates to physical form factor only. Both parts deliver identical electrical performance (3.5dBi gain, 1.5 VSWR) across the 2.4GHz ~ 2.5GHz frequency range. Height difference is a mechanical consideration for chassis integration, not electrical performance.

Q: What is the inventory status for these parts?

A: SQ2303P12NF: 930 Pcs New Original In Stock. SQ2403PG12NF: 927 Pcs New Original In Stock. Both parts maintain current inventory availability.
