BA-4030 Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The BA-4030 is a coaxial connector adapter manufactured by CUI Devices that converts between F Plug (male pin) and BNC Jack (female socket) configurations. This adapter is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration. The adapter operates in a straight, free-hanging (in-line) mounting configuration with threaded fastening on both connection ends.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA-4030 is determined by strict alignment of the following electrical and mechanical parameters:

• Adapter Series: BNC to F conversion capability
• Adapter Type: Plug to Jack configuration
• Center Gender: Female to Male pin conversion
• Convert From: F Plug, Male Pin interface
• Convert To: BNC Jack, Female Socket interface
• Style: Straight orientation
• Mounting Type: Free Hanging (In-Line) configuration
• Fastening Type: Threaded connections on both ends
• RoHS Compliance: Required for regulatory alignment

The Winchester Interconnect part number 8313505 satisfies all mandatory substitution criteria. This part maintains identical adapter series, type, gender configuration, and mounting characteristics while providing additional specifications including 50 Ohms impedance, gold-plated center contacts, and an extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Winchester Interconnect 8313505 is the qualified substitute for the obsolete BA-4030. Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility. The 8313505 is currently in active production status, providing supply chain continuity for new designs and replacement applications.

The primary distinction between the parts is the fastening mechanism on the BNC end: the BA-4030 uses threaded fastening, while the 8313505 employs bayonet lock fastening. This difference does not affect functional compatibility in applications where either fastening method is acceptable. The 8313505 provides additional documented specifications including 50 Ohms impedance, gold-plated center contacts, brass body construction with nickel finish, and an operating temperature range of -55°C to 100°C, which support broader application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Winchester Interconnect 8313505 directly replace the BA-4030 in existing installations?

A: The 8313505 maintains identical adapter series (BNC to F), adapter type (Plug to Jack), center gender configuration (Female to Male), and mounting style (Straight, Free Hanging). The fastening mechanism differs on the BNC end (bayonet lock versus threaded), which may require mechanical interface verification in the specific application.

Q: What are the key parameters that define substitution eligibility for this adapter?

A: Substitution is determined by matching the adapter series (BNC to F), adapter type (Plug to Jack), center gender (Female to Male), connector ends (F Plug to BNC Jack), style (Straight), and mounting type (Free Hanging, In-Line). RoHS compliance status must also align.

Q: Does the BA-4030 have impedance specifications?

A: The BA-4030 impedance is not specified in the available documentation. The 8313505 substitute is rated at 50 Ohms, which is the standard impedance for BNC and F connectors in RF applications.

Q: Are there differences in environmental ratings between these parts?

A: Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating. The 8313505 provides an operating temperature specification of -55°C to 100°C, while the BA-4030 operating temperature is not documented.

Q: What is the significance of the fastening type difference?

A: The BA-4030 uses threaded fastening on both ends, while the 8313505 uses bayonet lock on the BNC end and threaded fastening on the F end. Both fastening methods provide secure connections; selection depends on the mating connector type in the application.
