Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 910A205G is determined by strict alignment of core electrical and mechanical parameters. The substitute part 225532-1 qualifies based on the following criteria:

Matching Parameters (Required for Substitution):

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Operating Temperature Range: -65°C to 165°C
• Mating Cycles: 500
• Number of Ports: 1
• Center Contact Material: Brass
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Fastening Type: Threaded

Frequency Specification: The substitute part operates at 12.4 GHz maximum frequency, which is within 0.1 GHz of the primary part's 12.5 GHz specification and remains suitable for equivalent RF applications.

Cable Group Compatibility: The primary part supports RG-59 cable group, while the substitute supports RG-58A and RG-58C cable groups. These represent different cable impedance and construction specifications and should be verified for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (910A205G): The Winchester Interconnect 910A205G remains the specified component when original part continuity is required. This part maintains active product status, RoHS compliance, and unlimited moisture sensitivity rating (MSL 1), indicating no special handling requirements during storage or assembly.

Substitute Part Selection (225532-1): The TE Connectivity 225532-1 qualifies as an electrical and mechanical equivalent for applications requiring SMA male plug connectors with 50-ohm impedance and crimp termination. This part carries military specification compliance (MIL-PRF-39012) and ROHS3 certification. Selection of this substitute requires verification of cable group compatibility, as the substitute supports RG-58A and RG-58C cable groups rather than RG-59. The stainless steel body material of the substitute part differs from the nickel-finished brass body of the primary part, which may affect corrosion resistance characteristics in specific environmental conditions.

Compliance Considerations: Both parts maintain RoHS compliance and share identical operating temperature ranges and mating cycle ratings. The substitute part's military specification designation may provide additional qualification benefits for defense and aerospace applications.

Frequently Asked Questions (FAQ)

Q: Can 225532-1 be used as a direct replacement for 910A205G?

A: The 225532-1 is electrically and mechanically equivalent for SMA male plug connector applications requiring 50-ohm impedance and crimp termination. However, cable group compatibility must be verified. The primary part supports RG-59 cable, while the substitute supports RG-58A and RG-58C cables. Confirm that your application cable specifications align with the substitute part's supported cable groups before implementation.

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

A: The primary differences are: (1) Body material—910A205G uses nickel-finished brass; 225532-1 uses stainless steel; (2) Cable group support—910A205G supports RG-59; 225532-1 supports RG-58A and RG-58C; (3) Military specification—225532-1 carries MIL-PRF-39012 designation; 910A205G does not; (4) Insertion loss—225532-1 specifies 0.3 dB; 910A205G does not provide this specification; (5) Frequency rating—910A205G operates to 12.5 GHz; 225532-1 operates to 12.4 GHz.

Q: Are both parts RoHS compliant?

A: Yes. The 910A205G is RoHS compliant. The 225532-1 is ROHS3 compliant, which represents a more recent revision of the RoHS directive and includes additional restricted substances.

Q: What is the moisture sensitivity level for each part?

A: The 910A205G has MSL 1 (Unlimited), indicating no moisture sensitivity and no special storage or handling requirements. The 225532-1 has MSL listed as Not Applicable, which typically indicates the part does not require moisture sensitivity classification.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Mechanical and electrical interchangeability depends on cable group compatibility. If your assembly uses RG-59 cable, the 910A205G is the appropriate selection. If your assembly uses RG-58A or RG-58C cable, the 225532-1 is suitable. The threaded fastening type is identical for both parts, supporting mechanical compatibility at the mating interface.

Q: What is the maximum frequency rating difference between these parts?

A: The 910A205G operates to 12.5 GHz, while the 225532-1 operates to 12.4 GHz. This 0.1 GHz difference is negligible for most RF applications and does not prevent substitution in equivalent frequency bands.

Q: Which part should be selected for military or aerospace applications?

A: The 225532-1 carries explicit military specification compliance (MIL-PRF-39012) and is manufactured by TE Connectivity Aerospace, Defense and Marine. If military specification compliance is a requirement, the 225532-1 is the appropriate selection. The 910A205G does not carry military specification designation.
