TE Connectivity Laird P1664 RF Antenna Equivalent & Substitute Parts

Part Overview

The TE Connectivity Laird P1664 is a 164MHz Yagi 4-Element RF antenna designed for UHF bracket mount applications in the VHF frequency band (f < 300MHz). This antenna operates across the 162MHz to 166MHz frequency range with a gain of 6.5dBi and supports maximum power handling of 400W. The P1664 is classified as obsolete product status, making identification of equivalent and substitute parts essential for system continuity and procurement planning. Substitute parts must maintain compatibility with bracket mount installation, operate within overlapping frequency ranges, and support equivalent or superior electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1664 are identified based on strict alignment with the following critical parameters:

Frequency Compatibility: Substitute parts must operate within or encompass the P1664 operating range of 162MHz to 166MHz. Both substitute parts (Y1503 and Y1505) operate across 150MHz to 174MHz, which fully contains the P1664 frequency band.

Mounting Configuration: All substitute parts must support bracket mount installation to ensure mechanical compatibility with existing system designs.

Manufacturer Consistency: All substitute parts are manufactured by TE Connectivity Laird, ensuring design philosophy and quality standards alignment.

Termination Type Consideration: The P1664 uses UHF termination, while substitute parts Y1503 and Y1505 use N Type Female termination. This represents a connector interface change that requires mechanical adapter or system redesign consideration.

Power Handling: The P1664 supports 400W maximum power. Substitute parts Y1503 and Y1505 support 300W maximum power, representing a reduction in power handling capacity.

Antenna Element Configuration: The P1664 uses a 4-Element Yagi configuration. Substitute Y1503 uses 3-Element configuration (lower gain), while Y1505 uses 5-Element configuration (higher gain).

Engineering Selection Recommendations

For Y1503 Selection: Y1503 is an active product with current manufacturing support and ROHS3 compliance. This substitute operates within the P1664 frequency band with broader frequency coverage (150MHz to 174MHz). The 3-Element Yagi configuration provides 7.1dBd gain, which is higher than the P1664 6.5dBi gain. However, maximum power handling is reduced to 300W. Termination change from UHF to N Type Female requires connector interface modification. Physical height is reduced by approximately 4.75 inches, which may provide installation advantages in space-constrained applications.

For Y1505 Selection: Y1505 is an active product with current manufacturing support and RoHS compliance. This substitute operates within the P1664 frequency band with broader frequency coverage (150MHz to 174MHz). The 5-Element Yagi configuration provides 9.2dBd gain, representing significant gain improvement over the P1664. Maximum power handling is reduced to 300W. Termination change from UHF to N Type Female requires connector interface modification. Physical height is reduced by approximately 4.5 inches. Y1505 is suitable for applications requiring enhanced directional gain and narrower beam width characteristics.

Product Status Consideration: Both Y1503 and Y1505 maintain active product status with ongoing manufacturer support, ensuring long-term availability and technical documentation access. The P1664 obsolete status necessitates transition planning to active alternatives.

Frequently Asked Questions (FAQ)

Q: Can Y1503 or Y1505 directly replace P1664 without modification? A: Direct mechanical replacement is possible due to bracket mount compatibility. However, connector interface modification is required due to termination type change from UHF to N Type Female. System redesign or adapter implementation is necessary.

Q: What is the frequency compatibility between P1664 and substitute parts? A: The P1664 operates 162MHz to 166MHz. Both Y1503 and Y1505 operate 150MHz to 174MHz, fully encompassing the P1664 frequency band. Frequency compatibility is confirmed for both substitutes.

Q: How do gain characteristics differ between P1664 and substitutes? A: P1664 provides 6.5dBi gain with 4-Element configuration. Y1503 provides 7.1dBd gain with 3-Element configuration. Y1505 provides 9.2dBd gain with 5-Element configuration. Gain unit differences (dBi vs dBd) reflect different reference standards; dBd values are approximately 2.15dB higher than equivalent dBi values.

Q: What is the power handling limitation when using substitutes? A: P1664 supports 400W maximum power. Both Y1503 and Y1505 support 300W maximum power. Applications exceeding 300W power levels cannot use these substitutes.

Q: Are there compliance differences between P1664 and substitutes? A: P1664 is RoHS Compliant. Y1503 is ROHS3 Compliant. Y1505 is RoHS Compliant. All parts are REACH Unaffected or equivalent. Compliance requirements are met by all options.

Q: What physical installation differences exist? A: P1664 height is 44.000 inches. Y1503 height is 39.250 inches. Y1505 height is 39.500 inches. Both substitutes are approximately 4.5 to 4.75 inches shorter, which may affect radiation pattern and installation clearance requirements.

Q: Which substitute provides better performance for gain-critical applications? A: Y1505 with 9.2dBd gain provides the highest directional gain among all options. Y1503 with 7.1dBd gain provides intermediate gain. Selection depends on specific application gain requirements and power handling constraints.
