Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5909-1103-000 is determined by strict equivalence across the following critical parameters:

• Adapter type: Jack to Jack
• Adapter series: SMA to SMA
• Center gender: Female to Female
• Impedance: 50 Ohms
• Style: Straight
• Mounting type: Panel Mount with Bulkhead feature
• Fastening type: Threaded connections
• Body material: Stainless Steel with Gold finish
• Center contact material: Beryllium Copper
• Dielectric material: PTFE
• Mating cycles: 500
• RoHS3 compliance

The substitute part 901-9209A (Amphenol RF) meets all mandatory electrical and mechanical parameters for direct substitution. Frequency rating differences do not preclude substitution when the substitute part's maximum frequency specification exceeds the application requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the 5909-1103-000 and 901-9209A are active production parts with ROHS3 compliance and REACH compliance status. Selection between these parts should be based on:

• Inventory availability and procurement lead times
• Application frequency requirements (901-9209A rated to 12.4 GHz; 5909-1103-000 rated to 18 GHz)
• Operating temperature range requirements (901-9209A specifies -65°C ~ 165°C)
• Supplier preference and cost considerations
• Packaging requirements (901-9209A includes lockwasher and nut; 5909-1103-000 supplied in bulk)

Frequently Asked Questions (FAQ)

Q: Can 901-9209A replace 5909-1103-000 in all applications?

A: Yes, for applications operating at or below 12.4 GHz. The 901-9209A meets all mandatory electrical and mechanical parameters. If your application requires operation above 12.4 GHz, the 5909-1103-000 with its 18 GHz rating is required.

Q: What is the difference in packaging between these parts?

A: The 5909-1103-000 is supplied in bulk packaging. The 901-9209A includes three components per unit: one connector, one lockwasher, and one nut, which may simplify assembly in some applications.

Q: Are both parts RoHS compliant?

A: Yes, both 5909-1103-000 and 901-9209A are ROHS3 compliant and REACH affected.

Q: What are the mating cycle specifications?

A: Both parts are rated for 500 mating cycles, indicating equivalent mechanical durability.

Q: Does the frequency rating difference affect substitution eligibility?

A: The frequency rating difference does not preclude substitution when the substitute part's maximum frequency meets or exceeds the application requirement. If your circuit operates below 12.4 GHz, the 901-9209A is a valid substitute.

Q: What is the impedance specification for both adapters?

A: Both parts are 50 ohm impedance adapters, maintaining signal integrity across SMA jack-to-jack connections.
