SMA Plug to N Jack Coaxial Adapter 320990005

Part Overview

The 320990005 is a coaxial connector adapter manufactured by Seeed Technology Co., Ltd, designed to convert between SMA Plug (male pin) and N Jack (female socket) interfaces. This adapter operates at 50 Ohms impedance and supports frequencies up to 3 GHz. The product is classified as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this connector type is required.

Substitute Part Grouping Explanation

Substitution of the 320990005 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Adapter Series: SMA to N (conversion between these two connector types only)
Adapter Type: Plug to Jack (directional requirement)
Center Gender: Female to Male (pin configuration)
Impedance: 50 Ohms (electrical characteristic)
Style: Straight (mechanical form factor)
Mounting Type: Free Hanging (In-Line) (installation method)
Fastening Type: Threaded, Threaded (connection mechanism)

Compliance Parameters:

RoHS Compliant status
Moisture Sensitivity Level 1

The substitute part VA502 (Cinch Connectivity Solutions) meets all mandatory matching parameters and compliance requirements. While VA502 demonstrates enhanced specifications in frequency range (11 GHz versus 3 GHz) and operating temperature range (-65°C to 165°C), these represent performance improvements rather than deviations from the core functional specification.

Engineering Selection Recommendations

For Direct Substitution:

VA502 (Cinch Connectivity Solutions) is the qualified substitute for 320990005. Both parts are RoHS Compliant and carry Moisture Sensitivity Level 1 (Unlimited), meeting regulatory and environmental requirements. The substitution is valid based on matching adapter series, connector types, impedance, and mechanical form factors.

Product Status Consideration:

The 320990005 is classified as Obsolete. VA502 is classified as Active production status, ensuring long-term availability and supply chain continuity. For new designs or system replacements, VA502 is the appropriate selection.

Performance Characteristics:

VA502 provides enhanced frequency capability (11 GHz maximum versus 3 GHz) and specified operating temperature range (-65°C to 165°C), along with documented mating cycle rating (500 cycles). These characteristics represent performance improvements and do not create incompatibility with applications designed for the 320990005 specification.

Frequently Asked Questions (FAQ)

Q: Can VA502 be used as a direct replacement for 320990005 in existing systems?

A: Yes. Both adapters share identical adapter series (SMA to N), connector types (Plug to Jack), impedance (50 Ohms), and mechanical form factors (Straight, Free Hanging, Threaded fastening). The functional interface is equivalent.

Q: What is the primary reason to substitute 320990005?

A: The 320990005 is Obsolete. VA502 is Active production status, providing assured availability and supply chain support for current and future applications.

Q: Are there compliance differences between the two parts?

A: No. Both parts are RoHS Compliant and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Does the higher frequency rating of VA502 (11 GHz vs. 3 GHz) affect compatibility?

A: No. Higher frequency capability is a performance enhancement. Applications designed for 3 GHz operation function correctly with VA502, which supports that frequency range and beyond.

Q: What packaging differences exist?

A: 320990005 packaging is not specified in available data. VA502 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the physical dimensions identical?

A: Both adapters are Straight style, Free Hanging (In-Line) with Threaded fastening. Mechanical compatibility is established through these matching form factors. Consult manufacturer datasheets for detailed dimensional drawings if precision fit verification is required.

Q: What is the mating cycle rating for 320990005?

A: The mating cycle rating for 320990005 is not specified. VA502 is rated for 500 mating cycles.
