S1856MPC10NF RF Panel Antenna Equivalent & Substitute Parts

Part Overview

The S1856MPC10NF is a 1.9GHz panel RF antenna manufactured by TE Connectivity Laird, designed for LTE and WiMax™ applications. This component operates across the 1.85GHz to 1.99GHz frequency band with 6dBic gain and features an N Type Female connector for chassis mount installation. The product is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring compatible RF antenna solutions in the UHF frequency range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1856MPC10NF is determined by the following critical parameters:

Mandatory Matching Criteria:

• Frequency Range: 1.85GHz ~ 1.99GHz (1.9GHz center band)
• Antenna Type: Panel configuration
• Termination: N Type Female connector
• Frequency Group: UHF (1GHz ~ 2GHz)

Allowable Variation Parameters:

• Gain: Substitute may differ (original 6dBic; tolerance for system-level performance)
• VSWR: Substitute may differ (original 1.5; acceptable range depends on application impedance matching requirements)
• Mounting Type: Chassis Mount or Wall Mount (both are fixed installation methods)
• Power Rating: Substitute must meet or exceed 75 W maximum power handling
• Product Status: Active status preferred for long-term availability

The S1858P12NF qualifies as a substitute based on matching frequency range, antenna type, N Type Female termination, and UHF frequency group classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The S1856MPC10NF is classified as obsolete. The S1858P12NF is an active product from the same manufacturer, ensuring continued availability, technical support, and supply chain reliability for new designs and replacement applications.

Electrical Compatibility

Both parts operate within the identical 1.85GHz to 1.99GHz frequency band with N Type Female termination, satisfying core RF interface requirements. The S1858P12NF provides 8dBi gain compared to the original 6dBic, representing a 2dB improvement in directional performance. The VSWR increase from 1.5 to 2.0 remains within acceptable limits for standard RF system impedance matching (50 ohm systems).

Mechanical and Installation Differences

The primary distinction is mounting configuration: S1856MPC10NF uses chassis mount installation, while S1858P12NF uses wall mount. System integration must accommodate this difference. The S1858P12NF has a reduced maximum height (32.00mm versus 38.00mm), which may provide installation advantages in space-constrained applications.

Regulatory and Compliance Status

Both parts carry identical ECCN classification (5A991G) and MSL rating (1 - Unlimited), confirming equivalent regulatory treatment and environmental handling requirements.

Selection Basis

Choose S1858P12NF when:

• Obsolescence mitigation is required
• Wall mount installation is feasible or preferred
• Higher antenna gain (8dBi) benefits system performance
• Active product status and manufacturer support are necessary

Frequently Asked Questions (FAQ)

Q: Can S1858P12NF directly replace S1856MPC10NF in existing installations?

A: Electrical substitution is valid based on matching frequency range, antenna type, and N Type Female termination. However, mounting configuration differs (wall mount versus chassis mount), requiring mechanical redesign of the installation bracket or enclosure interface.

Q: What is the significance of the gain difference (6dBic versus 8dBi)?

A: The S1858P12NF provides 2dB higher directional gain. In RF systems, this typically translates to improved signal strength in the antenna's primary radiation direction. System link budget analysis should confirm whether this gain increase is beneficial or requires attenuation adjustment to maintain proper signal levels.

Q: Does the VSWR increase from 1.5 to 2.0 affect system performance?

A: VSWR of 2.0 is acceptable for most cellular and WiMax™ applications operating at 1.9GHz. Impedance matching networks in the RF chain typically accommodate this level of reflection. Verify specific system requirements if return loss specifications are critical.

Q: Are there any compliance or export restrictions affecting substitution?

A: Both parts share identical ECCN classification (5A991G), confirming equivalent export control treatment. No additional compliance barriers exist for substitution from a regulatory standpoint.

Q: What is the cable length difference between these parts?

A: S1856MPC10NF includes a 254mm cable; S1858P12NF includes a 305mm cable. The 51mm difference may affect routing and installation layout in confined spaces.

Q: Is the S1858P12NF suitable for LTE and WiMax™ applications?

A: The S1858P12NF is specified for PCS applications at 1.9GHz. The frequency band overlap (1.85GHz ~ 1.99GHz) with LTE and WiMax™ standards makes it functionally compatible for these applications, though the original design intent differs.

Q: What is the inventory status for these parts?

A: S1856MPC10NF has 1192 pieces in stock (obsolete status). S1858P12NF has 689 pieces in stock (active product). For long-term supply assurance, S1858P12NF is the recommended choice.
