Equivalent & Substitute Parts for 910A205M SMA Connector Plug

Part Overview

The 910A205M is an SMA connector plug manufactured by Winchester Interconnect, designed for RF coaxial applications requiring 50-ohm impedance. This free-hanging, in-line crimp connector operates at frequencies up to 12.5 GHz and is rated for -65°C to 165°C. The part is currently active in production with 794 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 910A205M is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Connector style must be SMA
Connector type must be Plug, Male Pin
Impedance must be 50 Ohms
Maximum frequency must be 12.4 GHz or higher
Dielectric material must be PTFE

Mechanical Equivalence Requirements:

Contact termination must be Crimp
Shield termination must be Crimp
Mounting type must be Free Hanging (In-Line)
Fastening type must be Threaded
Number of ports must be 1
Mating cycles must be 500 or greater

Compliance Requirements:

RoHS compliance status must be equivalent or superior
ECCN classification must match (EAR99)

The substitute part 2903-6001 from Amphenol SV Microwave meets all electrical and mechanical equivalence criteria. Both parts support the RG-174 cable group and operate within compatible frequency ranges.

Engineering Selection Recommendations

Both the 910A205M and 2903-6001 are active production parts with equivalent electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Inventory Availability: The 910A205M has 794 units in stock, while the 2903-6001 has 1140 units available.

Compliance Status: Both parts meet current regulatory requirements. The 910A205M carries RoHS Compliant status, while the 2903-6001 carries ROHS3 Compliant status, representing equivalent compliance levels.

Cable Compatibility: The 2903-6001 supports a broader cable group range (RG-174, 179B, 187A, 188A, 316) compared to the 910A205M (RG-174 only). This expanded compatibility may provide flexibility in system integration.

Packaging: The 910A205M is supplied with 3 pieces per connector (connector, contact, ferrule), while the 2903-6001 is supplied with 2 pieces per connector (connector, heat shrink). Assembly requirements should be evaluated based on application needs.

Frequently Asked Questions (FAQ)

Q: Can the 2903-6001 be used as a direct replacement for the 910A205M?

A: Yes. Both connectors meet equivalent electrical specifications (SMA plug, male pin, 50 ohms, crimp termination, 12.4+ GHz) and mechanical specifications (free-hanging, threaded, 500 mating cycles). They are functionally interchangeable in applications requiring these parameters.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Body material and finish (910A205M uses nickel-plated brass; 2903-6001 uses gold-plated stainless steel), (2) Cable group support (2903-6001 supports additional cable types), (3) Included components (910A205M includes ferrule; 2903-6001 includes heat shrink), and (4) Packaging format (910A205M is standard; 2903-6001 is bulk).

Q: Are there any frequency limitations when substituting these parts?

A: No. Both parts operate at 12.4 GHz or higher, meeting the same frequency requirements for 50-ohm SMA applications.

Q: Do both parts support the same operating temperature range?

A: The 910A205M specifies -65°C to 165°C. The 2903-6001 does not specify an operating temperature range in the provided data. Applications requiring confirmed temperature specifications should reference the 910A205M.

Q: Which part should be selected for new designs?

A: Selection should be based on specific application requirements, cable compatibility needs, and supply chain considerations. Both parts are active production items with equivalent electrical performance.

Q: Are there any RoHS or export compliance differences?

A: Both parts carry EAR99 ECCN classification and meet current RoHS requirements. No compliance barriers exist for substitution.
