PA2410 RF Antenna 2.4GHz Equivalent & Substitute Parts

Part Overview

The PA2410 is a 2.4GHz flat patch RF antenna manufactured by Murata Electronics, designed for UHF applications in the 2.4GHz to 2.5GHz frequency band. This antenna features MMCX chassis mount termination with 2dBi gain and 1.9 VSWR performance. The product is currently obsolete, making identification of functionally equivalent substitute parts essential for system redesign, legacy product support, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PA2410 are identified based on the following critical electrical and mechanical parameters:

Frequency Compatibility: Center frequency of 2.4GHz with operating range 2.4GHz ~ 2.5GHz is mandatory. All substitute parts must operate within this identical frequency band.

Termination Type: MMCX connector is required for direct mechanical and electrical compatibility with existing PCB layouts and cable assemblies.

Mounting Configuration: Chassis mount is the specified mounting method. Substitute parts must maintain this mounting approach.

Antenna Gain: 2dBi gain is the baseline performance specification. Substitute parts meeting this gain value ensure equivalent RF performance in the target application.

VSWR Performance: The PA2410 specifies 1.9 VSWR. Substitute parts with equal or superior (lower) VSWR values maintain or improve impedance matching characteristics.

Antenna Form Factor: While the PA2410 uses a flat patch design, substitute parts with alternative form factors (such as dome) are acceptable provided all electrical parameters remain equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

The S2402DSX24MMX from TE Connectivity Laird is a direct functional substitute for the PA2410. Both parts operate identically across the 2.4GHz ~ 2.5GHz frequency band with matching 2dBi gain and MMCX chassis mount configuration.

The S2402DSX24MMX offers improved VSWR performance at 1.7 compared to the PA2410's 1.9, resulting in superior impedance matching and reduced signal reflection. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain identical moisture sensitivity classification (MSL 1 - Unlimited) and share the same HTSUS commodity code (8529.10.9100). The S2402DSX24MMX carries RoHS compliance certification, meeting modern environmental and regulatory requirements.

The primary design difference is antenna form factor: the PA2410 uses a flat patch design while the S2402DSX24MMX employs a dome configuration. This difference does not affect electrical performance within the specified frequency band and gain parameters. The dome design introduces a maximum height specification of 0.750" (19.05mm), which must be verified against available mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the S2402DSX24MMX directly replace the PA2410 without PCB modifications?

A: Yes. Both parts feature identical MMCX termination and chassis mount configuration. No PCB layout changes are required. Verify that the 0.750" (19.05mm) maximum height of the S2402DSX24MMX fits within the available vertical clearance of your enclosure.

Q: Are the electrical performance characteristics equivalent?

A: Yes. Both parts operate across 2.4GHz ~ 2.5GHz with 2dBi gain. The S2402DSX24MMX provides superior VSWR performance (1.7 versus 1.9), which improves impedance matching and reduces signal loss.

Q: What is the significance of the antenna form factor difference?

A: The PA2410 flat patch design and S2402DSX24MMX dome design represent different physical geometries but deliver identical electrical performance within the specified frequency band and gain parameters. Form factor selection depends on available mounting space and aesthetic requirements.

Q: Is the S2402DSX24MMX suitable for applications requiring long-term component availability?

A: Yes. The S2402DSX24MMX is in active production status, ensuring ongoing availability and supply chain support. The PA2410 is obsolete and no longer manufactured.

Q: Do both parts meet current environmental compliance standards?

A: The S2402DSX24MMX carries RoHS compliance certification. Both parts share identical moisture sensitivity classification (MSL 1 - Unlimited) and HTSUS commodity code (8529.10.9100).

Q: What is the impact of improved VSWR on system performance?

A: Lower VSWR indicates better impedance matching between the antenna and transmission line. The S2402DSX24MMX's 1.7 VSWR versus the PA2410's 1.9 VSWR reduces signal reflection and improves overall RF efficiency in the 2.4GHz band.
