Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OD58M-12 is determined by the following critical parameters:

Frequency Compatibility: The substitute part must operate within or encompass the 5.47GHz to 5.85GHz frequency band to maintain RF performance in WiMax™ and WLAN applications.

Antenna Gain: The substitute must provide 12dBi gain to ensure equivalent radiation characteristics and system link budget performance.

Antenna Type and Form Factor: The substitute must be a whip, straight antenna configuration to maintain mechanical compatibility with existing mounting structures.

Termination Type: While the OD58M-12 features N Type Male termination, substitute parts may include N Type Female termination provided that appropriate adapter interfaces are available in the system design.

Power Rating: The substitute must support a maximum power rating of 100W to handle the same RF power levels.

Mounting Configuration: The substitute must support bracket mount installation to ensure mechanical integration with existing equipment.

VSWR Performance: The substitute must maintain a VSWR of 1.5 or better to ensure acceptable impedance matching and return loss characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OD58-12 serves as a direct functional substitute for the obsolete OD58M-12. Both parts are manufactured by TE Connectivity Laird and share identical RF performance specifications including frequency range, gain, VSWR, and power rating.

The primary distinction between these parts is the termination type: OD58M-12 features N Type Male termination while OD58-12 features N Type Female termination. System designers must account for this difference through appropriate connector interfaces or adapter solutions.

The OD58-12 holds Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS Compliance and equivalent environmental ratings (MSL 1 - Unlimited), supporting long-term reliability in production environments.

For applications requiring the exact N Type Male termination of the original OD58M-12, the OD58-12 with N Type Female termination can be integrated through standard N Type Male-to-Female adapter connectors, which are widely available industry components.

Frequently Asked Questions (FAQ)

Q: Can the OD58-12 directly replace the OD58M-12 without modifications?

A: The OD58-12 provides equivalent RF performance and mechanical mounting compatibility. However, the termination difference (N Type Female vs. N Type Male) requires an appropriate connector adapter or interface modification in the system design.

Q: Are the frequency ranges identical between OD58M-12 and OD58-12?

A: Yes. Both parts operate across the 5.47GHz to 5.85GHz frequency band with a 5.7GHz center frequency, ensuring equivalent RF coverage for WiMax™ and WLAN applications.

Q: What is the impact of the different termination types on system performance?

A: The termination type affects the physical connector interface but does not alter RF performance characteristics. Both N Type Male and N Type Female connectors provide equivalent impedance matching when properly mated with corresponding connector types.

Q: Is the OD58-12 available in the same packaging as the OD58M-12?

A: The OD58M-12 is packaged in standard format, while the OD58-12 is supplied in Bulk packaging. Both represent the same antenna component with identical RF specifications.

Q: Why is the OD58M-12 classified as Obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The OD58-12, with Active status, represents the current production equivalent and is recommended for new designs and ongoing support applications.

Q: Are both parts RoHS compliant?

A: Yes. Both OD58M-12 and OD58-12 are RoHS Compliant, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the maximum physical height difference between these antennas?

A: The OD58M-12 has a maximum height of 0.602" (15.30mm), while the OD58-12 has a maximum height of 27.559" (700.00mm). This significant difference reflects different physical form factors and must be evaluated for mechanical fit in the target application.
