ANT-433-WRT-SMA Equivalent & Substitute Parts

Part Overview

The ANT-433-WRT-SMA is a 433MHz dome RF antenna manufactured by TE Connectivity Linx, designed for ISM band applications including alarms, remote control, and security systems. This active product operates across the 425MHz to 441MHz frequency range with SMA male panel mount termination. The antenna is RoHS compliant and carries MSL 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified frequency band and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ANT-433-WRT-SMA is determined by the following criteria:

• Frequency Compatibility: Substitute parts must operate within or encompass the 425MHz to 441MHz band
• Antenna Type: Dome configuration required for form factor compatibility
• Termination: SMA Male connector mandatory for interface compatibility
• Mounting Configuration: Panel mount requirement for installation compatibility
• Frequency Group: UHF band (300MHz ~ 1GHz) classification
• Compliance Status: Active product status with current RoHS certification

The identified substitute IS.01.B.305111 meets all substitution criteria through overlapping frequency coverage (400MHz ~ 460MHz encompasses 425MHz ~ 441MHz), identical antenna type, matching SMA male termination, and panel mount configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the ANT-433-WRT-SMA and IS.01.B.305111 maintain active product status with current compliance certifications. The ANT-433-WRT-SMA carries RoHS compliance, while the substitute IS.01.B.305111 carries ROHS3 compliance, representing an equivalent or enhanced regulatory position. Both parts are REACH unaffected and classified under EAR99 export control.

The substitute part demonstrates improved VSWR performance (1.8 versus 1.9) and higher gain (1.6dBi versus -0.9dBi). The frequency range of IS.01.B.305111 (400MHz ~ 460MHz) fully encompasses the operating band of ANT-433-WRT-SMA (425MHz ~ 441MHz). Physical height difference is 2mm (29mm versus 27mm), which may require verification against available panel mounting clearance in the target application.

Selection between these parts should be based on specific application requirements regarding gain characteristics, available mounting space, and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can IS.01.B.305111 be used as a direct replacement for ANT-433-WRT-SMA?

A: Yes, IS.01.B.305111 meets the core substitution criteria: frequency range encompasses the original specification, antenna type is identical (dome), termination matches (SMA male), and mounting configuration is compatible (panel mount). Physical height difference of 2mm must be verified against available mounting space.

Q: What are the key differences between these two antennas?

A: The primary differences are gain (1.6dBi versus -0.9dBi), VSWR (1.8 versus 1.9), and physical height (29mm versus 27mm). The substitute part offers improved impedance matching and higher gain performance. Frequency coverage is broader on the substitute part (400MHz ~ 460MHz versus 425MHz ~ 441MHz).

Q: Are both parts RoHS compliant?

A: Yes. ANT-433-WRT-SMA is RoHS compliant. IS.01.B.305111 is ROHS3 compliant, which represents current RoHS directive compliance. Both parts are REACH unaffected.

Q: What is the significance of the VSWR difference?

A: VSWR (Voltage Standing Wave Ratio) indicates impedance matching quality. The substitute part's VSWR of 1.8 represents slightly better impedance matching compared to 1.9, resulting in lower reflection losses in the transmission line.

Q: Does the gain difference affect application suitability?

A: Gain difference of 2.5dBi is significant and application-dependent. The substitute part's positive gain (1.6dBi) provides signal amplification, while the original part's negative gain (-0.9dBi) represents attenuation. Application requirements determine which characteristic is appropriate.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bag packaging. ANT-433-WRT-SMA has 887 pieces in stock. IS.01.B.305111 has 1201 pieces in stock. Verify current inventory status with your supplier before component selection.
