ANT-433-CW-HW RF Antenna Equivalent & Substitute Parts

Part Overview

The ANT-433-CW-HW is a 433MHz whip antenna manufactured by TE Connectivity Linx, designed for ISM band applications including alarms, remote control, and security systems. This straight-mount RP-SMA connector antenna operates across the 418MHz to 448MHz frequency range with 0dBi gain and a VSWR of 2. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified frequency band and connector interface requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ANT-433-CW-HW is determined by the following criteria:

Mandatory Matching Parameters:

• Center frequency within or overlapping the 433MHz band
• Whip antenna type (physical form factor)
• UHF frequency group classification
• Connector mount installation method
• Active product status
• RoHS compliance certification

Allowable Variations:

• Connector gender/type (RP-SMA Male to SMA Male) when mechanical compatibility is maintained
• Mounting orientation (straight to right angle) when application space permits
• VSWR and Return Loss values within acceptable operational ranges for the frequency band
• Height/physical dimensions when connector interface remains compatible

The substitute part TI.10.0112 meets these criteria through overlapping 433MHz center frequency operation, whip antenna configuration, UHF band classification, and equivalent RoHS compliance status.

Engineering Selection Recommendations

ANT-433-CW-HW Selection Criteria:

• Applications requiring straight antenna orientation with maximum height of 120mm
• Systems designed for RP-SMA Male connector interface
• Designs requiring operational bandwidth across the full 418MHz to 448MHz range
• Existing inventory availability (691 pcs in stock)

TI.10.0112 Selection Criteria:

• Applications where right-angle antenna orientation is acceptable or preferred
• Systems compatible with standard SMA Male connector interface
• Space-constrained designs benefiting from 44.80mm height (62% reduction vs. main part)
• Improved impedance matching required (VSWR 1.5 vs. 2.0)
• Designs operating within the narrower 433MHz to 434MHz frequency band
• Compliance with ROHS3 standard required
• Higher inventory availability (1039 pcs in stock)

Both parts maintain active product status, RoHS compliance, MSL 1 rating, and REACH unaffected status. Selection between these parts depends on connector type compatibility, physical space constraints, and frequency bandwidth requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can TI.10.0112 directly replace ANT-433-CW-HW in existing designs?

A: Direct replacement requires verification of two factors: (1) connector compatibility—the main part uses RP-SMA Male while the substitute uses standard SMA Male, requiring adapter or redesign; (2) physical space—the substitute is 62% shorter (44.80mm vs. 120mm), which may be advantageous or require antenna placement reconsideration.

Q: What is the frequency band difference between these parts?

A: The ANT-433-CW-HW operates across 418MHz to 448MHz (30MHz bandwidth), while TI.10.0112 operates across 433MHz to 434MHz (1MHz bandwidth). The substitute covers only the center frequency region. Applications requiring operation outside 433MHz to 434MHz cannot use the substitute.

Q: Are both parts RoHS compliant?

A: Yes. ANT-433-CW-HW is RoHS Compliant, and TI.10.0112 is ROHS3 Compliant. Both meet RoHS requirements; the substitute meets the newer ROHS3 standard.

Q: What does the VSWR difference mean for performance?

A: VSWR of 1.5 (TI.10.0112) indicates better impedance matching than VSWR of 2.0 (ANT-433-CW-HW). Lower VSWR reduces signal reflection and improves efficiency. The substitute provides superior impedance characteristics at 433MHz.

Q: Can I use these antennas interchangeably in my PCB design?

A: No. The connector types differ (RP-SMA Male vs. SMA Male), and the mounting orientations differ (straight vs. right angle). PCB layout and connector footprints must be verified before substitution. Additionally, the frequency range difference must be evaluated against your application's operational requirements.

Q: Which part should I choose for new designs?

A: For new designs, evaluate: (1) required frequency bandwidth—if operation outside 433MHz to 434MHz is needed, use ANT-433-CW-HW; (2) physical space—if compact form factor is required, TI.10.0112 offers significant height reduction; (3) connector standard—verify which connector type your system architecture supports; (4) impedance requirements—if optimal matching is critical, TI.10.0112 provides lower VSWR.
