TE Connectivity Laird QWB8963 RF Antenna Equivalent & Substitute Parts

Part Overview

The TE Connectivity Laird QWB8963 is a 933MHz whip straight RF antenna with NMO base mount termination, designed for UHF frequency applications within the 896MHz to 970MHz band. This component delivers 3dB gain and is rated for base mount installation with a maximum height of 15.500 inches (393.70mm).

The QWB8963 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where this component is specified in existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QWB8963 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency (Center/Band): 933MHz
• Frequency Range: 896MHz ~ 970MHz
• Antenna Type: Whip, Straight
• Termination: NMO
• Mounting Type: Base Mount
• Gain: 3dB
• Height (Max): 15.500" (393.70mm)
• Number of Bands: 1

Compliance Parameters:

• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must satisfy all mandatory matching parameters to ensure functional and mechanical compatibility. Compliance certifications must be maintained or equivalent.

Parameter Comparison

Engineering Selection Recommendations

QW8963 as Primary Substitute:

The QW8963 is a direct functional equivalent to the QWB8963. All critical electrical and mechanical parameters align precisely: identical frequency specifications (933MHz center, 896MHz–970MHz range), antenna configuration (whip, straight), termination (NMO), mounting type (base mount), gain (3dB), and physical dimensions (15.500" maximum height).

Both parts maintain RoHS compliance and MSL 1 (Unlimited) ratings, ensuring regulatory and environmental compatibility.

The QW8963 carries an Active product status, providing supply continuity and long-term availability compared to the obsolete QWB8963. The packaging difference (Bulk for QW8963 versus unspecified for QWB8963) does not affect functional performance and may offer procurement flexibility.

For new designs or production continuity, the QW8963 is the appropriate selection where the QWB8963 is specified.

Frequently Asked Questions (FAQ)

Q: Can the QW8963 replace the QWB8963 in existing applications?

A: Yes. The QW8963 matches all critical parameters of the QWB8963: frequency band (933MHz, 896–970MHz range), antenna type (whip, straight), termination (NMO), mounting (base mount), gain (3dB), and physical height (15.500"). Both parts are RoHS compliant with MSL 1 ratings. Functional and mechanical compatibility is confirmed.

Q: What is the primary difference between QWB8963 and QW8963?

A: The QW8963 is the active production variant of the QWB8963. The QWB8963 is obsolete. Packaging is specified as Bulk for QW8963. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain RoHS compliance and MSL 1 (Unlimited) ratings. Regulatory and environmental certifications are equivalent.

Q: What parameters must match for a valid substitute?

A: Frequency specifications (933MHz center, 896–970MHz range), antenna type (whip, straight), termination (NMO), mounting type (base mount), gain (3dB), and physical dimensions (15.500" height) must all match. RoHS and MSL compliance must be maintained.

Q: Is the QW8963 available in stock?

A: Yes. The QW8963 has 1105 pieces in new original stock, providing immediate availability for procurement and production use.
