RF Antenna X000003 Equivalent & Substitute Parts

Part Overview

The X000003 is a multiband RF antenna manufactured by Arduino, designed for cellular applications including GPRS and GSM protocols. This antenna operates across four frequency bands: 850MHz, 900MHz, 1.8GHz, and 1.9GHz, with a whip and tilt configuration featuring SMA Male connector termination. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy system maintenance, and component sourcing continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X000003 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency band coverage: 850MHz, 900MHz, 1.8GHz, 1.9GHz
• Antenna type: Whip, Tilt configuration
• Termination: SMA Male connector
• Mounting type: Connector Mount
• RF Family/Standard: Cellular

Allowable Variation Parameters:

• Gain: The substitute may exceed the original specification (1dBi minimum)
• VSWR: Must remain at or below 2
• Return Loss: May be unspecified if VSWR is maintained
• Height: Minor dimensional variation acceptable within mechanical constraints
• Applications: May include additional protocols (UMTS, GPRS, GSM)
• Product Status: Active status preferred for ongoing availability
• Compliance certifications: RoHS and REACH status may differ

The DELTA7B/X/SMAM/S/S/11 manufactured by Siretta Ltd qualifies as a direct substitute based on identical frequency band coverage, antenna configuration, connector type, and mounting method.

Parameter Comparison

Engineering Selection Recommendations

The DELTA7B/X/SMAM/S/S/11 is the designated substitute for the obsolete X000003. Selection is based on the following engineering criteria:

Functional Equivalence: Both antennas operate across identical frequency bands (850MHz, 900MHz, 1.8GHz, 1.9GHz) with matching antenna configuration (whip, tilt) and SMA Male termination. Connector mount installation is identical.

Performance Characteristics: The substitute maintains VSWR at 2, matching the original specification. The gain increase from 1dBi to 2dBi represents an improvement in antenna efficiency and does not introduce incompatibility.

Compliance Status: The DELTA7B/X/SMAM/S/S/11 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts share EAR99 export classification.

Product Availability: The substitute is classified as active, ensuring ongoing availability and supply chain continuity compared to the obsolete status of the original part.

Dimensional Compatibility: The height difference of 0.079" (2.00mm) between the two antennas is within typical mechanical tolerance ranges for connector-mount RF antennas and does not affect electrical performance or standard mounting interfaces.

Frequently Asked Questions (FAQ)

Q: Can the DELTA7B/X/SMAM/S/S/11 be used as a direct replacement for the X000003?

A: Yes. Both antennas operate across the same four frequency bands, use identical SMA Male connectors, and employ the same whip and tilt configuration. Connector mount installation is compatible.

Q: What is the significance of the gain difference (1dBi vs. 2dBi)?

A: The substitute antenna provides 1dB higher gain, indicating improved efficiency in signal transmission and reception. This represents a performance enhancement and does not create incompatibility with systems designed for the original antenna.

Q: Does the 2mm height difference affect installation?

A: No. The dimensional difference of 0.079" (2.00mm) is negligible for connector-mount RF antennas and falls within standard mechanical tolerances. Standard SMA mounting interfaces remain compatible.

Q: Are there protocol differences between the two antennas?

A: The substitute supports GPRS, GSM, and UMTS, while the original supports GPRS and GSM. The substitute is backward compatible with all original applications and adds UMTS capability.

Q: What is the packaging difference?

A: The original part number does not specify packaging, while the substitute is supplied in bulk packaging. Confirm bulk packaging compatibility with your procurement requirements.

Q: Are both antennas compliant with current regulations?

A: The substitute is ROHS3 compliant and REACH unaffected. Both parts share EAR99 export classification. Verify compliance requirements for your specific application and region.
