Substitute Part Grouping Explanation
Substitution of the AA.108.301F21 is determined by strict equivalence in the following electrical and mechanical parameters:
- Frequency Performance: Center frequency of 1.575GHz and frequency range of 1.57GHz ~ 1.58GHz
- Antenna Specifications: Module type antenna with 2dBic gain and 1.92 VSWR
- Physical Dimensions: Maximum height of 0.598" (15.20mm)
- Environmental Rating: IP67 ingress protection
- Integrated Features: 3-meter cable with LNA
- Compliance: ROHS3 compliant, REACH unaffected status
- Termination Interface: The primary difference among substitutes is the connector type
The AA.108.301111 qualifies as a manufacturer-recommended substitute because it maintains identical electrical performance (frequency, gain, VSWR), physical dimensions, environmental protection, integrated features, and compliance certifications. The only variation is the termination connector: AA.108.301111 uses SMA Male termination instead of GT5 Female.

Engineering Selection Recommendations
The AA.108.301111 is the manufacturer-recommended substitute for the discontinued AA.108.301F21. Both parts maintain identical electrical performance across all RF parameters, physical dimensions, environmental protection ratings, and compliance certifications (ROHS3 compliant, REACH unaffected).
The critical consideration for selection is connector compatibility. The AA.108.301F21 features a GT5 Female termination, while the AA.108.301111 features an SMA Male termination. System designs must accommodate this connector difference through appropriate interface adapters or redesign of mating connectors.
The AA.108.301111 is currently in active production status with higher inventory availability (2076 Pcs), providing supply chain continuity for GPS navigation applications requiring 1.575GHz module antennas with integrated LNA and 3-meter cable assemblies.
Frequently Asked Questions (FAQ)
Q: Can AA.108.301111 directly replace AA.108.301F21 without modification?
A: Direct replacement requires connector compatibility verification. The AA.108.301111 uses SMA Male termination while the AA.108.301F21 uses GT5 Female termination. System designs must either incorporate appropriate adapter connectors or modify mating connector interfaces.
Q: Are the RF performance characteristics identical between these parts?
A: Yes. Both parts operate at 1.575GHz center frequency with 1.57GHz ~ 1.58GHz frequency range, 2dBic gain, and 1.92 VSWR. Electrical performance is equivalent for GPS navigation applications.
Q: What are the physical mounting considerations?
A: Both parts use adhesive mounting with identical maximum height of 0.598" (15.20mm). Physical installation footprint and mounting procedures are equivalent.
Q: Are there compliance or regulatory differences?
A: No. Both parts are ROHS3 compliant and REACH unaffected. Compliance certifications are identical.
Q: Why is AA.108.301F21 discontinued?
A: Product discontinuation at DiGi Electronics does not indicate technical obsolescence. The AA.108.301111 remains in active production as the current Taoglas offering for this antenna category.
Q: What is the inventory status for each part?
A: AA.108.301F21 has 745 Pcs available as new original stock. AA.108.301111 has 2076 Pcs available as new original stock and is actively produced.
