Molex 0733860202 Coaxial Connector Equivalent & Substitute Parts

Part Overview

The Molex 0733860202 is an SMB Jack to SMA Jack adapter coaxial connector classified as an RF coaxial connector. This component functions as an interface adapter enabling connection between SMB and SMA connector series in RF applications. The part maintains Active product status with 1035 units in current inventory stock.

Identification of equivalent and substitute parts becomes necessary when primary component availability is limited, when supply chain requirements mandate multiple qualified sources, or when design specifications permit interchangeable adapter configurations that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial connector adapters is determined by the following parameters:

Adapter Configuration: The adapter must convert between identical connector series (SMB to SMA or SMA to SMB).

Connector Gender and Pin Configuration: The gender configuration of both connector ends must align with the application requirement (Jack to Jack, Jack to Plug, or equivalent mating configurations).

Impedance Rating: The characteristic impedance must match the primary part specification (50 Ohms standard for RF applications).

Frequency Operating Range: The maximum frequency rating must equal or exceed the application requirement.

Environmental Compliance: Product status must be Active, and regulatory compliance (RoHS, REACH, ECCN) must be equivalent or superior.

Moisture Sensitivity: MSL rating must be equivalent or lower (more permissive).

The Amphenol RF 901-9033 qualifies as a substitute based on matching adapter series conversion (SMA to SMB), identical impedance (50 Ohms), equivalent MSL rating (1 - Unlimited), matching ECCN classification (EAR99), and Active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The Molex 0733860202 remains the specified component when design documentation explicitly calls for this part number and supply availability is confirmed.

Substitute Part Selection: The Amphenol RF 901-9033 is qualified as an equivalent substitute when the following conditions are met:

1. Design specifications permit adapter series conversion between SMB and SMA connectors without directional constraint.
2. Application requirements do not mandate specific manufacturer qualification.
3. Both parts maintain Active product status and identical regulatory compliance (EAR99, MSL 1).
4. Inventory availability of the primary part is insufficient for production or procurement timelines.

Both parts comply with identical export control classifications (ECCN EAR99) and harmonized tariff codes (HTSUS 8536.69.4010), supporting interchangeable procurement and logistics handling.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 901-9033 directly replace the Molex 0733860202 in existing designs?

A: The Amphenol RF 901-9033 functions as a substitute adapter for SMB-to-SMA conversion. Both parts are Jack-to-Jack adapters with identical impedance and regulatory compliance. Substitution is valid when design specifications do not mandate a specific manufacturer or part number.

Q: What is the difference between SMB-to-SMA and SMA-to-SMB adapter orientation?

A: These designations indicate the connector series at each end of the adapter. An SMB-to-SMA adapter has an SMB connector on one end and an SMA connector on the other. The functional result is identical regardless of designation order when both ends are Jack-type connectors.

Q: Are there packaging or form factor differences between these parts?

A: Both parts are specified as Free Hanging (In-Line) adapters with Snap-On and Threaded fastening. No packaging differences are documented in the provided specifications.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts carry identical Moisture Sensitivity Level (MSL 1 - Unlimited), ECCN classification (EAR99), and HTSUS codes (8536.69.4010). The Amphenol RF 901-9033 additionally specifies ROHS3 compliance and REACH affected status.

Q: What is the maximum operating frequency for these adapters?

A: The Amphenol RF 901-9033 specifies a maximum frequency of 4 GHz. The Molex 0733860202 frequency specification is not provided in the available documentation.

Q: Can these adapters be used in high-temperature applications?

A: The Amphenol RF 901-9033 operates across -65°C to 165°C. Operating temperature specifications for the Molex 0733860202 are not provided in the available documentation.
