Molex 2144141011 ISM/DSRC Antenna Equivalent & Substitute Parts
Part Overview
The Molex 2144141011 is a 5.9GHz DSRC and ISM band whip antenna with hinged, tilt-capable design. This component operates across the 5.8GHz to 6GHz frequency range and provides 3.9dBi gain with RP-SMA male connector termination for direct integration into RF systems. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new design implementations.

Substitute Part Grouping Explanation
Substitution eligibility for the Molex 2144141011 is determined by strict equivalence across the following critical parameters: frequency range (5.8GHz ~ 6GHz), center frequency (5.9GHz), antenna type classification (whip with tilt capability), gain specification (3.9dBi), return loss performance (-10dB), connector type (RP-SMA male), mounting methodology (connector mount), physical height (4.268" maximum), and application domain (DSRC/ISM). The substitute part must maintain identical electrical performance characteristics and mechanical form factor to ensure drop-in compatibility within existing or new system designs. RoHS3 compliance and equivalent regulatory classification (ECCN EAR99, HTSUS 8517.71.0000) are required for procurement and deployment continuity.

Engineering Selection Recommendations
The Molex 2144140011 serves as the direct active equivalent for the obsolete Molex 2144141011. Both components share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The 2144140011 maintains ROHS3 compliance and carries the same ECCN and HTSUS classifications, ensuring regulatory continuity for procurement and deployment. The transition from the obsolete 2144141011 to the active 2144140011 presents no technical barriers and is supported by complete parameter equivalence across all critical RF and mechanical attributes. The 2144140011 is available in tray packaging with substantially higher inventory levels (2627 units versus 992 units), providing improved supply chain reliability for ongoing production and support requirements.
Frequently Asked Questions (FAQ)
Q: Can the Molex 2144140011 replace the Molex 2144141011 in existing designs?
A: Yes. The 2144140011 is electrically and mechanically identical to the 2144141011 across all specified parameters, including frequency range, gain, return loss, connector type, and physical dimensions. Direct substitution is supported without design modification.
Q: What is the primary difference between these two part numbers?
A: The 2144141011 is classified as obsolete, while the 2144140011 is active. The packaging differs (the 2144140011 is supplied in tray format), and inventory availability is substantially higher for the active part. All electrical and mechanical specifications remain identical.
Q: Are both parts RoHS3 compliant?
A: Yes. Both the 2144141011 and 2144140011 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8517.71.0000) classifications.
Q: Does the packaging difference affect RF performance?
A: No. Packaging format (tray versus other configurations) does not affect the antenna's electrical performance, frequency response, gain, or return loss characteristics. The RF specifications remain identical.
Q: What applications are supported by both parts?
A: Both components are specified for DSRC (Dedicated Short Range Communications) and ISM (Industrial, Scientific, Medical) band applications operating in the 5.8GHz to 6GHz frequency range.
Q: Is the RP-SMA male connector identical on both parts?
A: Yes. Both parts feature RP-SMA male connectors with identical specifications and mounting methodology.
