SMA Connector Plug 910A904M Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 910A904M is an SMA connector plug designed for RF coaxial applications requiring 50-ohm impedance termination. This male pin connector features crimp termination for both center contact and shield, supporting free-hanging in-line mounting configurations. The part is actively produced and maintained in inventory, with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to supply chain considerations, specific cable compatibility requirements, or procurement preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 910A904M is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMA (ensures mechanical interface compatibility)
• Connector Type: Plug, Male Pin (ensures mating with SMA jack receptacles)
• Impedance: 50 Ohms (ensures electrical performance in RF circuits)
• Contact Termination: Crimp (ensures assembly compatibility with existing tooling and processes)
• Shield Termination: Crimp (ensures assembly compatibility with existing tooling and processes)
• Mounting Type: Free Hanging (In-Line) (ensures physical installation compatibility)
• Fastening Type: Threaded (ensures mating mechanism compatibility)

Important Alignment Parameters:

• Frequency - Max: 12.4 GHz or higher (ensures operational bandwidth capability)
• Operating Temperature: Must support -65°C minimum and 165°C maximum or equivalent range
• Mating Cycles: 500 or higher (ensures mechanical durability equivalence)
• RoHS Compliance: Required for regulatory alignment

The Amphenol SV Microwave 2903-6001 meets all mandatory matching parameters and important alignment criteria, qualifying it as a direct substitute for the 910A904M.

Parameter Comparison

Engineering Selection Recommendations

910A904M (Winchester Interconnect) is the primary specification part with active product status, RoHS compliance, and unlimited moisture sensitivity rating (MSL 1). This part is suitable for applications requiring standard environmental conditions and standard moisture exposure.

2903-6001 (Amphenol SV Microwave) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The 2903-6001 provides equivalent performance with ROHS3 compliance and is available in bulk packaging. The stainless steel body material of the 2903-6001 offers enhanced corrosion resistance compared to the brass body of the 910A904M, making it suitable for applications with elevated environmental stress requirements. Both parts support identical cable groups with minor variations (2903-6001 supports RG-179B and RG-187A in addition to common groups).

Selection between these parts should be based on:

• Procurement availability and lead time requirements
• Cable compatibility with specific cable group requirements
• Environmental exposure conditions (stainless steel body preferred for corrosive environments)
• Packaging requirements (bulk versus standard packaging)
• Existing inventory and supply chain preferences

Frequently Asked Questions (FAQ)

Q: Can the 2903-6001 be used as a direct replacement for the 910A904M in existing designs?

A: Yes. Both connectors meet identical specifications for SMA plug male pin configuration, 50-ohm impedance, crimp termination, free-hanging mounting, and threaded fastening. Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What is the difference in operating temperature between these parts?

A: The 910A904M specifies operating temperature range of -65°C to 165°C. The 2903-6001 does not provide an explicit operating temperature specification in the available data. For applications requiring confirmed temperature performance across the full -65°C to 165°C range, the 910A904M is the specified choice.

Q: Are there cable compatibility differences between these connectors?

A: Both connectors support RG-174, RG-188, and RG-316 cable groups. The 2903-6001 additionally supports RG-179B and RG-187A. The 910A904M does not list support for these additional cable types. If your application uses RG-179B or RG-187A cables, the 2903-6001 is the appropriate selection.

Q: What is the significance of the body material difference (brass versus stainless steel)?

A: The 910A904M uses a brass body with gold finish, while the 2903-6001 uses a stainless steel body with gold finish. Both materials are suitable for RF connector applications. Stainless steel provides superior corrosion resistance in harsh or marine environments. Brass is standard for general RF applications. Material selection should align with environmental exposure conditions.

Q: Do these connectors have different packaging considerations?

A: The 910A904M is supplied with 1 connector, 1 contact, and 1 ferrule per unit. The 2903-6001 is supplied with 1 connector and 1 heat shrink per unit. The 2903-6001 is available in bulk packaging, while the 910A904M packaging type is not specified. Verify inclusion requirements for your assembly process.

Q: Are both parts RoHS compliant?

A: Yes. The 910A904M is RoHS Compliant. The 2903-6001 is ROHS3 Compliant. Both meet RoHS regulatory requirements. ROHS3 represents the current RoHS directive version and is fully compatible with RoHS requirements.

Q: What is the maximum frequency specification for each connector?

A: The 910A904M supports frequencies up to 12.5 GHz. The 2903-6001 supports frequencies up to 12.4 GHz. Both connectors operate within standard SMA frequency ranges. For applications requiring operation at or above 12.5 GHz, the 910A904M is the specified choice.

Q: Can these connectors be used interchangeably in the same assembly?

A: Yes, provided that cable compatibility requirements are met and environmental operating conditions do not exceed the specifications of either part. Both connectors are mechanically and electrically compatible with standard SMA jack receptacles and support identical mating cycles (500 cycles).
