Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA24-180-14 is determined by strict alignment across the following critical parameters:

Core Compatibility Criteria:

• Frequency Range: Must operate within or encompass 2.4GHz ~ 2.485GHz band
• Antenna Type: Panel configuration required
• Termination: N Type Female connector mandatory
• Mounting Type: Bracket Mount configuration required
• RF Family/Standard: WiFi/WiMax™ applications
• Frequency Group: UHF (2GHz ~ 3GHz)
• VSWR and Return Loss: Must meet or exceed specified performance (VSWR 1.5, Return Loss -14dB)
• Power Rating: Minimum 100 W handling capability
• Connector Type and Mechanical Interface: Direct compatibility with existing system integration points

The MD24-12 qualifies as a substitute part based on alignment across all core compatibility parameters, despite variations in gain specification and physical height.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The SA24-180-14 carries Obsolete status, indicating discontinued manufacturing and limited availability. The MD24-12 substitute maintains Active product status with confirmed inventory of 981 pieces in stock, providing supply chain continuity for ongoing production and field replacement requirements.

Compliance and Regulatory Alignment

Both parts share identical ECCN classification (5A991G), confirming equivalent export control treatment. The MD24-12 includes RoHS Compliant certification, meeting modern environmental and regulatory standards. MSL ratings are identical (1 - Unlimited), indicating equivalent moisture sensitivity handling requirements.

Performance Parameter Alignment

The MD24-12 maintains critical electrical specifications: identical VSWR (1.5), Return Loss (-14dB), and maximum power handling (100 W). Frequency range coverage is functionally equivalent, with both parts operating across the 2.4GHz band required for Wi-Fi and WiMax™ applications. The primary performance differential is gain specification: SA24-180-14 delivers 14dBi versus MD24-12 at 12dBi, representing a 2dBi reduction in directional gain.

Mechanical Integration

Physical height differs significantly: SA24-180-14 measures 7.087" (180.00mm) versus MD24-12 at 4.016" (102.00mm). This dimensional reduction may provide installation advantages in space-constrained applications while maintaining identical N Type Female termination and bracket mount configuration.

Selection Basis

Selection of MD24-12 as substitute is justified by: (1) Active product status ensuring supply availability, (2) Identical core electrical performance parameters, (3) Equivalent regulatory and compliance certifications, (4) Identical connector type and mounting interface, and (5) Functional frequency band coverage for specified applications.

Frequently Asked Questions (FAQ)

Q: Can MD24-12 directly replace SA24-180-14 in existing installations?

A: MD24-12 provides functional substitution based on identical termination type (N Type Female), mounting configuration (Bracket Mount), frequency band coverage (2.4GHz), and core electrical specifications (VSWR 1.5, Return Loss -14dB, 100 W power rating). Physical height reduction from 180mm to 102mm requires verification of mechanical clearance in the installation environment.

Q: What is the significance of the 2dBi gain difference between SA24-180-14 (14dBi) and MD24-12 (12dBi)?

A: Gain differential of 2dBi represents a measurable reduction in directional antenna performance. System designers must evaluate whether this reduction impacts link budget calculations, coverage patterns, or signal strength requirements for the specific application. This parameter should be assessed against system performance margins and operational requirements.

Q: Are there packaging differences between SA24-180-14 and MD24-12?

A: SA24-180-14 packaging is listed as standard configuration. MD24-12 is supplied in Bulk packaging. Procurement and handling procedures may differ accordingly. Confirm packaging requirements with supply chain and inventory management protocols.

Q: Do both parts meet current regulatory requirements?

A: Both parts share identical ECCN classification (5A991G). MD24-12 includes explicit RoHS Compliant certification. SA24-180-14 status as Obsolete may limit availability of current compliance documentation. For new designs or regulatory-sensitive applications, MD24-12 provides documented compliance assurance.

Q: What is the frequency range overlap between these two antennas?

A: SA24-180-14 operates 2.4GHz ~ 2.485GHz. MD24-12 operates 2.4GHz ~ 2.483GHz. Overlap range is 2.4GHz ~ 2.483GHz, covering standard Wi-Fi and WiMax™ operational bands. The 2GHz difference at the upper frequency limit is negligible for typical 2.4GHz band applications.

Q: Is MD24-12 suitable for WiMax™ applications specified for SA24-180-14?

A: MD24-12 specifications explicitly list WiMax™ and WLAN applications. Frequency range, connector type, and electrical performance parameters support WiMax™ deployment. Functional compatibility is confirmed across specified application categories.

Q: What inventory status should influence component selection?

A: SA24-180-14 is Obsolete with 768 pieces in current stock. MD24-12 is Active with 981 pieces in stock. For long-term production planning and supply chain stability, Active status with confirmed inventory provides superior availability assurance.
