WIH-AT-CAB24IN Equivalent & Substitute Parts

Part Overview

The WIH-AT-CAB24IN is a 916MHz whip tilt RF antenna manufactured by Thomas Research Products, designed for panel mount applications with RP-SMA male termination and a 610mm cable. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system design and maintenance requirements. The antenna operates within the UHF frequency band (300MHz ~ 1GHz) and is rated MSL 1 (unlimited moisture sensitivity).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WIH-AT-CAB24IN are identified based on the following critical parameters:

• Frequency compatibility within the 916MHz ISM band
• Antenna type classification (whip configuration)
• Termination type (RP-SMA male connector)
• Mounting methodology (panel mount or adhesive mount)
• Physical dimensions and cable length considerations
• Active product status and RoHS compliance

The two identified substitutes—ANT-916-MHW-RPS-L and ANT-916-PML—both operate at 916MHz center frequency with compatible termination and mounting approaches. Both substitute parts are manufactured by TE Connectivity Linx and maintain active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

ANT-916-MHW-RPS-L is suitable for applications requiring adhesive mounting with extended cable length (4.6m). This substitute maintains RP-SMA male termination and operates across a broader frequency range (816MHz ~ 1.016GHz). The center-fed double whip configuration provides 5.4dBi gain. This part is RoHS compliant and maintains active product status.

ANT-916-PML is suitable for panel mount applications requiring direct solder termination. This substitute maintains the whip tilt antenna type and panel mount methodology of the original part. Cable length is reduced to 305mm. This part is RoHS compliant and maintains active product status. The frequency range (881MHz ~ 951MHz) encompasses the 916MHz center frequency with -0.4dBi gain specification.

Both substitutes provide RoHS compliance, addressing regulatory requirements not met by the obsolete WIH-AT-CAB24IN. Selection between substitutes depends on mounting methodology requirements and termination type compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can ANT-916-MHW-RPS-L directly replace WIH-AT-CAB24IN in panel mount applications?

A: ANT-916-MHW-RPS-L uses adhesive mounting rather than panel mount. While frequency and termination are compatible, the mounting methodology differs. System redesign may be required.

Q: What is the primary difference between the two substitute parts?

A: ANT-916-MHW-RPS-L uses adhesive mounting with extended cable length (4.6m) and center-fed double whip configuration. ANT-916-PML uses panel mount with solder termination and shorter cable length (305mm), more closely matching the original mounting approach.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ANT-916-MHW-RPS-L and ANT-916-PML are RoHS compliant, whereas the original WIH-AT-CAB24IN is RoHS non-compliant.

Q: Does frequency compatibility guarantee direct substitution?

A: No. While both substitutes operate at 916MHz center frequency, differences in antenna type, mounting methodology, termination type, and physical dimensions must be evaluated against specific application requirements.

Q: What cable length considerations apply to substitution?

A: The original part includes 610mm cable. ANT-916-MHW-RPS-L provides 4.6m cable, while ANT-916-PML provides 305mm cable. Cable length requirements must be verified for each application.

Q: Can ANT-916-PML be used with RP-SMA connectors?

A: ANT-916-PML uses solder termination, not RP-SMA male connector. Connector adaptation or system redesign is required for compatibility with RP-SMA systems.
