WIH-AT-FA-36 Equivalent & Substitute Parts

Part Overview

The WIH-AT-FA-36 is a 916MHz whip straight RF antenna with RP-SMA male panel mount termination, manufactured by Thomas Research Products as part of the wiHUBB® series. This component is designed for UHF applications operating in the 916MHz frequency band with a cable length of 914mm and a maximum height of 51.00mm. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, maintenance, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WIH-AT-FA-36 is determined by the following critical parameters:

• Frequency Compatibility: Center frequency or frequency range must encompass 916MHz
• Antenna Type: Whip configuration (straight or center-fed double acceptable)
• Termination: RP-SMA Male connector required
• VSWR: Maximum 1.9 or better
• Frequency Group: UHF band operation (300MHz ~ 1GHz)
• Number of Bands: Single-band operation

The identified substitute parts meet these criteria while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

ANT-916-CW-RH provides the closest functional equivalence to the WIH-AT-FA-36. Both components feature identical physical height (51.00mm), matching VSWR (1.9), and RP-SMA male termination. The ANT-916-CW-RH operates at 915MHz with a frequency range of 900MHz ~ 935MHz, encompassing the original 916MHz specification. This substitute is manufactured by TE Connectivity Linx, carries active product status, and meets RoHS compliance requirements. The connector mount configuration differs from the original panel mount, requiring mechanical redesign consideration.

ANT-916-MHW-RPS-L offers an alternative with extended frequency coverage (816MHz ~ 1.016GHz) and higher gain performance (5.4dBi). This center-fed double whip antenna maintains VSWR and RP-SMA termination compatibility but introduces significant physical differences: increased height (138.00mm versus 51.00mm) and adhesive mounting instead of panel mount. This substitute is suitable only for applications where mechanical envelope constraints can be accommodated. The ANT-916-MHW-RPS-L is active and RoHS compliant.

Both substitutes provide improved product lifecycle status and regulatory compliance compared to the obsolete WIH-AT-FA-36.

Frequently Asked Questions (FAQ)

Q: Can ANT-916-CW-RH directly replace WIH-AT-FA-36 in existing designs?

A: ANT-916-CW-RH meets all electrical parameters (frequency, VSWR, termination, gain specification). However, the mounting type differs: ANT-916-CW-RH uses connector mount while WIH-AT-FA-36 uses panel mount. Mechanical redesign of the mounting interface is required.

Q: What is the frequency compatibility between WIH-AT-FA-36 and its substitutes?

A: WIH-AT-FA-36 operates at 916MHz. ANT-916-CW-RH covers 900MHz ~ 935MHz (includes 916MHz). ANT-916-MHW-RPS-L covers 816MHz ~ 1.016GHz (includes 916MHz). Both substitutes provide frequency coverage encompassing the original specification.

Q: How do the physical dimensions affect substitution?

A: WIH-AT-FA-36 and ANT-916-CW-RH share identical maximum height (51.00mm), making them suitable for space-constrained applications. ANT-916-MHW-RPS-L reaches 138.00mm height and requires verification against available mounting space.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ANT-916-CW-RH and ANT-916-MHW-RPS-L are RoHS compliant. The original WIH-AT-FA-36 is RoHS non-compliant.

Q: What is the difference between connector mount and panel mount?

A: Panel mount (WIH-AT-FA-36) integrates the antenna directly into an enclosure panel. Connector mount (ANT-916-CW-RH) attaches via RP-SMA connector to a mating receptacle, allowing external antenna placement.

Q: Why does ANT-916-MHW-RPS-L have higher gain than the other options?

A: ANT-916-MHW-RPS-L uses a center-fed double whip configuration versus the straight whip design of WIH-AT-FA-36 and ANT-916-CW-RH. The dual-element design produces 5.4dBi gain compared to the single-element performance.
