Parameter Comparison

Engineering Selection Recommendations

The Molex 1461530200 is available as an active product with current manufacturing support, addressing the obsolescence status of the 0479502001. Both components maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

The primary consideration for selection involves termination type compatibility. The original part features SMT Male termination, while the substitute utilizes U.FL (UMCC) and IPEX MHF1 connectors. This difference requires verification of the receiving connector interface in the target application.

Frequency range coverage differs between the two parts. The substitute operates within 5.15GHz ~ 5.85GHz, which covers standard WLAN and Zigbee™ bands. The original part extends to 4.8GHz ~ 5.9GHz, providing broader upper-band coverage. Application requirements determine whether this variation impacts performance.

Gain specifications show minor differences: the substitute provides 2.6dBi and 4dBi versus the original 2.9dBi and 5dBi. These variations fall within typical antenna performance tolerances for dual-band applications.

Frequently Asked Questions (FAQ)

Q: Can the 1461530200 directly replace the 0479502001 without circuit modifications?

A: Direct mechanical and electrical replacement depends on connector compatibility. The original part uses SMT Male termination while the substitute uses U.FL (UMCC) and IPEX MHF1 connectors. The receiving circuit board connector must match the substitute termination type. If the original design uses SMT Male connectors, adapter solutions or circuit redesign may be required.

Q: Are the frequency ranges compatible for the same applications?

A: Both parts operate across 2.4GHz and 5GHz bands suitable for WLAN and Zigbee™ applications. The substitute's 5.15GHz ~ 5.85GHz range covers standard regulatory bands for these protocols. The original part's extended range to 4.8GHz provides additional coverage outside typical application requirements. For standard WLAN and Zigbee™ implementations, the substitute frequency range is sufficient.

Q: What is the impact of the gain difference between these parts?

A: The substitute provides 2.6dBi and 4dBi gain compared to the original 2.9dBi and 5dBi. These differences represent approximately 0.3dBi and 1dBi variations respectively. For most wireless applications, these differences fall within acceptable performance margins and do not typically require circuit compensation.

Q: Why is the antenna type different between these parts?

A: The original uses PCB trace antenna technology while the substitute employs flat patch antenna design. Both are established technologies for dual-band RF applications. The choice between them depends on available PCB real estate, desired radiation pattern, and mechanical integration requirements in the target application.

Q: Are both parts suitable for production use?

A: The substitute (1461530200) is classified as active product status with current manufacturing availability. The original (0479502001) is obsolete. For new designs or production continuity, the active substitute is the appropriate selection.
