Substitute Part Grouping Explanation

Substitution of the 2783.000.00.00 antenna is based on manufacturer classification and functional application category. The FEIG Electronic 3543.000.00 is listed as the manufacturer-recommended substitute. However, this substitute operates in fundamentally different frequency bands (865MHz – 868MHz and 902MHz – 928MHz UHF range) compared to the original 13.56MHz HF specification.

The substitution logic is based on:

• Common manufacturer (FEIG Electronic)
• Same product category (RFID antenna)
• EAR99 export classification alignment
• Identical MSL 1 rating for assembly compatibility
• ROHS3 compliance and REACH unaffected status in substitute

The frequency difference reflects a transition from HF to UHF RFID technology, suitable only for applications where frequency band migration is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The 3543.000.00 is the manufacturer-recommended alternative for 2783.000.00.00 based on FEIG Electronic's official substitution mapping. The substitute maintains identical MSL and export classification ratings, ensuring compatibility with existing supply chain and regulatory frameworks.

The substitute is currently in active production status with documented inventory availability, providing supply chain reliability advantages over the obsolete original part. ROHS3 compliance certification and REACH unaffected status in the substitute align with modern environmental standards.

Selection of the substitute requires evaluation of the frequency band transition from 13.56MHz HF to 865MHz – 928MHz UHF, as this affects system-level RFID reader compatibility and application functionality.

Frequently Asked Questions (FAQ)

Q: Why is the 2783.000.00.00 antenna no longer available? A: The part is obsolete. The 3543.000.00 is the manufacturer-recommended successor from FEIG Electronic.

Q: What is the primary difference between the original and substitute antenna? A: The original operates at 13.56MHz (HF band) while the substitute operates at 865MHz – 928MHz (UHF bands). This is a frequency technology transition rather than a direct frequency-compatible replacement.

Q: Are the physical dimensions compatible between the two antennas? A: No. The original is 100mm x 100mm, while the substitute is 75mm x 50mm x 3mm. PCB layout modifications may be required.

Q: Does the substitute maintain the same regulatory compliance? A: Both parts share EAR99 export classification and 8471.90.0000 HTSUS coding. The substitute includes ROHS3 compliance certification and REACH unaffected status, exceeding the original specifications.

Q: Can I use the substitute in equipment designed for 13.56MHz operation? A: No. RFID reader systems are frequency-specific. The substitute is only suitable for equipment designed for 865MHz – 928MHz UHF RFID operation.

Q: What is the moisture sensitivity rating of the substitute? A: Both parts maintain MSL 1 (Unlimited), requiring no special handling or storage constraints during PCB assembly.
