APAMS-101 Equivalent & Substitute Parts
Part Overview
The APAMS-101 is a 900MHz/1.8GHz GSM flat bar RF antenna manufactured by Abracon LLC. This dual-band cellular antenna operates across 820MHz–960MHz and 1.71GHz–1.99GHz frequency ranges with FME-J3 termination and adhesive mounting. The part is active and RoHS3 compliant. Substitute parts are identified based on matching frequency coverage, antenna type compatibility, termination options, and mounting method to ensure functional equivalence in GSM and cellular applications.

Substitute Part Grouping Explanation
Substitute parts for the APAMS-101 are grouped based on the following substitution criteria:
Primary Substitution Parameters:
- Frequency coverage: 900MHz and 1.8GHz bands (820MHz–960MHz, 1.71GHz–1.99GHz)
- Antenna type: Flat bar or flat patch configurations
- Mounting method: Adhesive mounting
- RF family/standard: Cellular (GSM, DCS, PCS)
- Termination compatibility: Connector types suitable for GSM applications
- Compliance: RoHS3 compliant, active product status
Substitution Logic: Parts are considered equivalent when they operate within the specified frequency ranges, support GSM and related cellular standards, use adhesive mounting, and maintain comparable electrical performance (VSWR, gain). Termination differences (FME-J3 vs. U.FL, IPEX MHF1, MMCX) are noted as they require connector adaptation but do not prevent functional substitution in circuit design.

Engineering Selection Recommendations
Cellular Band Substitutes (900MHz/1.8GHz GSM):
FXP07.07.0100A, FXP14.07.0100A, FXP14.09.0100A, FXP14.24.0100B, FXP14R.A.07.0100A, and FXP40.07.0085A are suitable substitutes for the APAMS-101 in GSM cellular applications. All parts are RoHS3 compliant and active products. These parts cover the 900MHz and 1.8GHz frequency bands required for GSM operation. Termination differences require connector adaptation: FXP parts use U.FL (UMCC), IPEX MHF1, or MMCX connectors instead of the FME-J3 termination on the APAMS-101.
Non-Cellular Substitutes (Wi-Fi Bands):
FXP522.A.07.A.001, FXP523.A.07.A.001, FXP810.07.0100C, and FXP810.09.0100C operate in 2.4GHz and 5GHz Wi-Fi frequency bands and are not suitable substitutes for GSM cellular applications. These parts are listed in the provided substitute list but do not meet the frequency requirements for the APAMS-101.
Selection Criteria:
- All recommended substitutes maintain RoHS3 compliance and active product status
- Adhesive mounting is consistent across all parts
- Frequency coverage for 900MHz and 1.8GHz bands is preserved
- Connector type selection depends on circuit board design requirements
Frequently Asked Questions (FAQ)
Q: Can FXP14.07.0100A replace APAMS-101 directly?
A: FXP14.07.0100A covers the required 900MHz and 1.8GHz GSM bands and uses adhesive mounting. However, it terminates with U.FL (UMCC) or IPEX MHF1 connectors instead of FME-J3, requiring connector adaptation on the circuit board.
Q: What is the difference between FXP14.07.0100A and FXP14.09.0100A?
A: Both parts operate at identical frequencies (850MHz, 900MHz, 1.7GHz, 1.8GHz, 1.9GHz, 2.1GHz) and antenna type (flat patch). The difference is termination: FXP14.07.0100A uses U.FL (UMCC) or IPEX MHF1, while FXP14.09.0100A uses MMCX Male. Select based on connector compatibility with your design.
Q: Why are FXP522.A.07.A.001 and FXP810.07.0100C listed as substitutes if they operate at different frequencies?
A: These parts are included in the provided substitute list but operate at 2.4GHz and 5GHz Wi-Fi bands, not GSM cellular bands. They are not functionally equivalent to the APAMS-101 for GSM applications.
Q: Does FXP40.07.0085A support all GSM frequency bands?
A: FXP40.07.0085A covers 850MHz, 900MHz, 1.8GHz, and 1.9GHz with frequency range 824MHz–896MHz and 1.71GHz–1.99GHz. This matches the APAMS-101 frequency coverage for GSM and DCS/PCS applications.
Q: What is the height difference between APAMS-101 and FXP14 series parts?
A: APAMS-101 has a maximum height of 0.276" (7.00mm), while FXP14 series parts measure 0.004" (0.10mm). The FXP14 series is significantly lower profile, which may affect circuit board layout and antenna performance in space-constrained designs.
Q: Are all substitute parts RoHS3 compliant?
A: Yes, all listed substitute parts from Taoglas Limited are RoHS3 compliant and maintain active product status, matching the compliance profile of the APAMS-101.
