WIH-AT-CAB48IN Equivalent & Substitute Parts

Part Overview

The WIH-AT-CAB48IN is a 916MHz whip tilt RF antenna manufactured by Thomas Research Products, designed for panel mount applications with RP-SMA male termination and 1.2m cable integration. This component operates within the UHF frequency band (300MHz ~ 1GHz) and is part of the wiHUBB® series. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the WIH-AT-CAB48IN is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency compatibility within the 916MHz ISM band (915MHz center frequency acceptable)
• Antenna type classification (whip configuration required)
• Termination type (RP-SMA male connector required for direct compatibility)
• Mounting methodology (panel mount or equivalent mechanical interface)
• UHF frequency group classification (300MHz ~ 1GHz)

Secondary Compatibility Factors:

• Cable integration and length specifications
• Physical height and form factor constraints
• Product status and availability
• Compliance certifications (RoHS status, REACH status)

The identified substitute parts ANT-916-MHW-RPS-S and ANT-916-PML both operate at 915MHz center frequency with overlapping frequency ranges that encompass the 916MHz operating point. Both maintain whip antenna configuration and UHF band operation. However, differences in mounting type, termination method, and cable specifications require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

ANT-916-MHW-RPS-S Selection Criteria: This substitute maintains RP-SMA male termination and whip antenna configuration with active product status and RoHS compliance. The frequency range (816MHz ~ 1.016GHz) encompasses the 916MHz operating point. However, the adhesive mounting type differs from the panel mount requirement of the original part, necessitating mechanical redesign. The extended cable length (2m versus 1.2m) and increased height (138mm versus 120mm) require spatial validation. This option is suitable for applications where adhesive mounting is acceptable and RoHS compliance is mandatory.

ANT-916-PML Selection Criteria: This substitute provides panel mount compatibility matching the original mechanical interface and maintains whip tilt antenna configuration. The frequency range (881MHz ~ 951MHz) covers the 916MHz operating point. However, the solder termination differs from the RP-SMA male connector, requiring connector integration or PCB redesign. The increased height (150.30mm versus 120mm) and reduced cable length (305mm versus 1.2m) demand application-specific validation. This option is suitable for applications where panel mount integration is critical and solder termination can be accommodated. RoHS compliance and active product status support long-term availability.

Both substitutes offer active product status and RoHS compliance, addressing obsolescence concerns of the original part. Selection depends on mechanical mounting constraints, termination compatibility, and spatial requirements specific to the target application.

Frequently Asked Questions (FAQ)

Q: Can ANT-916-MHW-RPS-S directly replace WIH-AT-CAB48IN without modification? A: Direct replacement is not possible. While both parts maintain RP-SMA male termination and whip antenna configuration, the adhesive mounting type of ANT-916-MHW-RPS-S differs from the panel mount requirement. Mechanical redesign is necessary to accommodate the adhesive mounting interface.

Q: What is the primary difference between ANT-916-PML and the original WIH-AT-CAB48IN? A: The ANT-916-PML uses solder termination instead of RP-SMA male connector. Both maintain panel mount configuration and whip tilt antenna type. Integration of an RP-SMA connector or PCB redesign for solder connection is required.

Q: Are both substitute parts compatible with 916MHz operation? A: Both substitutes operate at 915MHz center frequency with frequency ranges that encompass 916MHz. ANT-916-MHW-RPS-S covers 816MHz ~ 1.016GHz, and ANT-916-PML covers 881MHz ~ 951MHz. Both support the 916MHz operating point within their specified ranges.

Q: What compliance advantages do the substitute parts offer? A: Both ANT-916-MHW-RPS-S and ANT-916-PML are RoHS compliant and REACH unaffected, whereas the original WIH-AT-CAB48IN is RoHS non-compliant. For applications requiring regulatory compliance, either substitute addresses this requirement.

Q: How do cable length differences affect system design? A: The original part includes 1.2m cable. ANT-916-MHW-RPS-S provides 2m cable, and ANT-916-PML provides 305mm cable. Cable length impacts antenna placement flexibility and system layout. Selection depends on specific installation geometry and routing requirements.

Q: Which substitute is recommended for new designs? A: Selection depends on mechanical constraints. For panel mount applications with RP-SMA termination requirements, neither substitute provides a direct match. ANT-916-PML maintains panel mount but requires solder termination integration. ANT-916-MHW-RPS-S maintains RP-SMA termination but requires adhesive mounting accommodation. Engineering evaluation of specific application requirements is necessary.
