WIH-AT-CAB36IN RF Antenna Equivalent & Substitute Parts

Part Overview

The WIH-AT-CAB36IN is a 916MHz whip tilt RF antenna manufactured by Thomas Research Products, designed for panel mount applications with RP-SMA male termination and a 914mm cable. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The part operates within the UHF frequency band (300MHz ~ 1GHz) and is suitable for applications requiring fixed-frequency RF transmission and reception at 916MHz.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WIH-AT-CAB36IN is determined by alignment of the following critical parameters:

• Frequency Compatibility: Center frequency or frequency range must encompass 916MHz
• Antenna Type: Whip or tilt configuration required for form factor compatibility
• Mounting Interface: Panel mount configuration mandatory
• Termination Type: Connector type must support integration with existing RF circuits
• Physical Dimensions: Height and cable length must accommodate system constraints
• Product Status: Active status preferred for long-term availability and supply chain reliability

The ANT-916-PML from TE Connectivity Linx qualifies as a substitute based on these parameters. The part operates at 915MHz with a frequency range of 881MHz ~ 951MHz, encompassing the 916MHz center frequency of the original part. Both parts feature whip/tilt antenna configuration, panel mount design, and operate within the UHF band. However, termination and cable length differ, requiring evaluation for specific application requirements.

Engineering Selection Recommendations

The ANT-916-PML is suitable as a substitute for the WIH-AT-CAB36IN based on the following factors:

Frequency Alignment: The ANT-916-PML operates at 915MHz with a frequency range of 881MHz ~ 951MHz, which encompasses the 916MHz center frequency of the original part. Both parts operate within the UHF band and support the same frequency group classification.

Form Factor Compatibility: Both parts feature whip/tilt antenna configuration and panel mount design, ensuring mechanical compatibility with existing enclosure designs.

Product Status and Compliance: The ANT-916-PML holds active product status, ensuring ongoing availability and supply chain support. The part is RoHS compliant, meeting current environmental and regulatory requirements, whereas the original part is RoHS non-compliant.

Termination and Cable Considerations: The ANT-916-PML uses solder termination rather than RP-SMA male connector, and provides a 305mm cable versus the 914mm cable of the original part. These differences require circuit-level integration assessment to determine compatibility with existing RF interfaces and mechanical routing constraints.

Physical Dimensions: The ANT-916-PML has a maximum height of 5.917" (150.30mm) compared to 4.724" (120.00mm) for the original part. Space availability within the target enclosure must be confirmed.

Frequently Asked Questions (FAQ)

Q: Can the ANT-916-PML directly replace the WIH-AT-CAB36IN without modification?

A: Direct replacement requires evaluation of three factors: termination type (solder vs. RP-SMA male connector), cable length (305mm vs. 914mm), and physical height (150.30mm vs. 120.00mm). Circuit board layout and RF interface design must accommodate these differences.

Q: What is the frequency compatibility between these two parts?

A: The ANT-916-PML operates at 915MHz with a frequency range of 881MHz ~ 951MHz, which includes the 916MHz center frequency of the WIH-AT-CAB36IN. Both parts are suitable for 916MHz applications within the UHF band.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates the WIH-AT-CAB36IN is no longer manufactured by Thomas Research Products. The ANT-916-PML from TE Connectivity Linx provides an active alternative with equivalent functional characteristics.

Q: What are the key differences in electrical performance?

A: The ANT-916-PML provides specified electrical parameters including -0.4dBi gain and 1.9 VSWR. The original part does not include published gain or VSWR specifications. Both parts operate with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the ANT-916-PML meet current regulatory requirements?

A: The ANT-916-PML is RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards. The original part is RoHS non-compliant.

Q: What packaging is available for the ANT-916-PML?

A: The ANT-916-PML is supplied in bulk packaging, with 894 pieces available in new original stock condition.
