TE Connectivity Laird P4063 418MHz Yagi RF Antenna Equivalent & Substitute Parts

Part Overview

The TE Connectivity Laird P4063 is a 418MHz Yagi RF antenna designed for UHF applications within the 406MHz to 430MHz frequency range. This antenna features a 6dBi gain with UHF termination and bracket mount configuration, offering a maximum height of 15.354 inches (390.00mm). The P4063 is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and component sourcing. Substitute parts must maintain compatibility across frequency range, antenna type, mounting configuration, and termination specifications to ensure proper system performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4063 is determined by the following critical parameters that must remain consistent or compatible:

Mandatory Compatibility Parameters:

• Frequency range overlap: 406MHz ~ 430MHz with center frequency at 418MHz
• Antenna type: Yagi configuration
• Mounting type: Bracket mount
• Frequency group: UHF (300MHz ~ 1GHz)
• Number of bands: Single band operation
• RoHS compliance status
• Manufacturer: TE Connectivity Laird

Variable Parameters Allowing Substitution:

• Termination type (UHF to N Type Female)
• Gain specification (6dBi to 7.1dBd)
• Physical height (15.354" to 20.157")
• VSWR specification (not specified in P4063; 1.5 in substitute)
• Product status (Obsolete to Active)

The Y4063 qualifies as a manufacturer-recommended substitute because it maintains all mandatory compatibility parameters while offering improved electrical performance characteristics and active product status.

Engineering Selection Recommendations

The Y4063 is the manufacturer-recommended substitute for the obsolete P4063. Selection of this substitute is supported by the following engineering factors:

Product Status Justification: The P4063 is classified as obsolete, creating supply chain risk and limiting long-term availability. The Y4063 maintains active production status, ensuring reliable sourcing and consistent manufacturing quality.

Compliance and Certification: Both parts maintain RoHS compliance and identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring compatibility with current manufacturing and environmental standards.

Frequency and Antenna Compatibility: The Y4063 operates within the identical 406MHz to 430MHz frequency range with the same 418MHz center frequency and Yagi antenna configuration. This ensures functional equivalence in RF performance for the intended UHF application band.

Mechanical Compatibility: Both parts feature bracket mount configurations, allowing installation in existing mounting structures. The Y4063 has a maximum height of 20.157 inches compared to the P4063 at 15.354 inches. Installation verification is required to confirm adequate clearance in the target application.

Termination Consideration: The primary difference is the connector termination: P4063 uses UHF termination while Y4063 uses N Type Female termination. System integration requires evaluation of existing connector infrastructure and potential adapter requirements.

Performance Enhancement: The Y4063 provides improved electrical performance with 7.1dBd gain compared to the P4063 at 6dBi, and includes a specified VSWR of 1.5, offering better impedance matching characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Y4063 directly replace the P4063 without modifications?

A: The Y4063 is functionally equivalent for RF performance within the 406MHz to 430MHz frequency range. However, the termination type differs (N Type Female vs. UHF). Direct mechanical installation is possible due to identical bracket mount configuration, but connector compatibility must be verified in the target system. If the system uses UHF connectors, an adapter or connector modification is required.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: identical frequency range (406MHz ~ 430MHz), matching antenna type (Yagi), same mounting type (bracket mount), single band operation, and manufacturer consistency (TE Connectivity Laird). The Y4063 meets all these criteria.

Q: Does the height difference between P4063 (15.354") and Y4063 (20.157") affect compatibility?

A: The Y4063 is approximately 4.8 inches taller. Physical installation space must be verified to ensure the taller antenna does not create clearance issues, RF interference with nearby structures, or exceed system envelope constraints. Mechanical integration assessment is required before deployment.

Q: Are there any compliance or environmental differences between these parts?

A: Both parts are RoHS compliant and share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). No compliance or environmental differences exist between the two parts.

Q: What does the gain difference (6dBi vs. 7.1dBd) mean for system performance?

A: The Y4063 provides higher directional gain (7.1dBd) compared to the P4063 (6dBi). This results in improved signal reception and transmission efficiency in the intended direction. The substitute offers enhanced RF performance for the same frequency band.

Q: Is the Y4063 available in the same packaging as the P4063?

A: The P4063 packaging is listed as "-" (not specified), while the Y4063 is supplied in Bulk packaging. Packaging format should be confirmed with the supplier based on application requirements.

Q: What is the VSWR specification, and why does only the Y4063 list this parameter?

A: VSWR (Voltage Standing Wave Ratio) measures impedance matching quality at the antenna connector. The Y4063 specifies VSWR of 1.5, indicating good impedance matching. The P4063 does not provide this specification. The Y4063's specified VSWR of 1.5 represents acceptable performance for UHF antenna applications.
