AP.17B.07.0040A Equivalent & Substitute Parts

Part Overview

The AP.17B.07.0040A is a 1.575GHz GPS ceramic patch RF antenna manufactured by Taoglas Limited, featuring a U.FL (UMCC) IPEX MHF1 connector for surface mount applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The antenna delivers 1dBic gain with integrated LNA functionality and operates within the UHF frequency band (1GHz–2GHz) designated for GPS navigation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP.17B.07.0040A is determined by the following mandatory parameters:

• Center frequency: 1.575GHz (GPS band)
• Antenna type: Ceramic patch
• Termination connector: U.FL (UMCC), IPEX MHF1
• RF family/standard: Navigation
• Frequency group: UHF (1GHz–2GHz)
• VSWR: 2
• RoHS and REACH compliance status

The two identified substitute parts, AP.17F.07.0064A and AP.35A.07.0054A, maintain identical center frequency, antenna type, connector specification, and compliance certifications. Variations in gain (1dBic vs. –1.5dBic vs. 2.5dBic), mounting method (surface mount vs. solder), physical height, and feature set (LNA only vs. LNA with filter) represent design trade-offs within the same functional category and do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both AP.17F.07.0064A and AP.35A.07.0054A are active products with current manufacturing status, providing supply continuity for designs currently using the obsolete AP.17B.07.0040A. Both substitutes maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

AP.17F.07.0064A offers a compact form factor (4.00mm height) with integrated filter functionality alongside LNA, suitable for space-constrained applications. The –1.5dBic gain represents a 2.5dB reduction relative to the original part and must be evaluated against link budget requirements.

AP.35A.07.0054A provides the highest gain (2.5dBic) with the smallest profile (4.60mm height) and integrated filter. The solder termination method differs from the original surface mount approach and requires assembly process compatibility assessment.

Selection between substitutes depends on specific application constraints: physical height limitations, gain requirements, and assembly methodology compatibility.

Frequently Asked Questions (FAQ)

Q: Can AP.17F.07.0064A or AP.35A.07.0054A be used as direct replacements for AP.17B.07.0040A?

A: Both parts share the same center frequency (1.575GHz), antenna type (ceramic patch), connector specification (U.FL IPEX MHF1), and compliance certifications. Substitution is electrically and mechanically feasible. Gain differences (–1.5dBic and 2.5dBic respectively, versus 1dBic) and physical height variations must be evaluated against application-specific performance and layout requirements.

Q: What is the significance of the gain difference between these parts?

A: Gain directly affects received signal strength. AP.17F.07.0064A operates at –1.5dBic (2.5dB lower than the original), while AP.35A.07.0054A operates at 2.5dBic (1.5dB higher). GPS receiver sensitivity and link budget calculations determine acceptable gain ranges for a given application.

Q: How do the mounting methods differ?

A: AP.17B.07.0040A and AP.17F.07.0064A use surface mount termination. AP.35A.07.0054A uses solder termination, requiring different PCB assembly processes and connector preparation.

Q: What does the integrated filter in AP.17F.07.0064A and AP.35A.07.0054A provide?

A: The filter provides out-of-band rejection, reducing interference from non-GPS frequency sources. This feature is absent in the original AP.17B.07.0040A (LNA only).

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
