Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R125252000 is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Cable Group: RG-405 (.085" Semi Rigid)
• Fastening Type: Threaded
• Frequency - Max: 18 GHz
• Number of Ports: 1
• Center Contact Material: Beryllium Copper
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature: -65°C ~ 105°C
• Mating Cycles: 500

All identified substitute parts meet these mandatory parameters. Variations in packaging type (Box versus Bulk), body material composition, voltage rating, and moisture sensitivity level do not affect functional interchangeability for this connector category. Differences in these secondary parameters reflect manufacturing variations and supply chain options rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active in product status and comply with applicable environmental and regulatory standards. Selection among equivalent parts should be based on the following criteria:

Radiall USA, Inc. Parts (R125252000, 9431-1583-010, 9441-1083-010, R125256000): These parts are manufactured by the same original equipment manufacturer and maintain consistent quality standards. R125252000 and R125256000 are supplied in Box packaging, while 9431-1583-010 and 9441-1083-010 are supplied in Bulk packaging. All four parts are ROHS3 compliant. The primary distinction between R125252000 and R125256000 is the flange configuration (two-hole versus square flange), which does not affect electrical performance but may influence mechanical fit in specific panel mounting applications.

Rosenberger Part (32K401-271L5): This part is manufactured by Rosenberger and supplied in Bulk packaging. It is ROHS3 compliant and offers an extended operating temperature range of -65°C to 165°C and a higher voltage rating of 480 V compared to the R125252000. The 32K401-271L5 is suitable for applications requiring enhanced thermal performance or higher voltage tolerance.

Voltage Rating Considerations: The R125252000 and R125256000 are rated at 250 V. The 9431-1583-010 and 9441-1083-010 are rated at 350 V. The 32K401-271L5 is rated at 480 V. Applications operating at voltages exceeding 250 V should utilize substitute parts with corresponding higher voltage ratings.

Packaging and Moisture Sensitivity: R125252000 and R125256000 are supplied in Box packaging with Not Applicable moisture sensitivity level. The substitute parts 9431-1583-010, 9441-1083-010, and 32K401-271L5 are supplied in Bulk packaging with MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can R125252000 be directly replaced with 9431-1583-010?

A: Yes. Both parts are SMA female socket connectors with identical electrical specifications: 50 Ohm impedance, solder termination, 18 GHz maximum frequency, and -65°C to 105°C operating temperature range. The primary difference is packaging type (Box versus Bulk) and voltage rating (250 V versus 350 V). The higher voltage rating of 9431-1583-010 does not create incompatibility; it indicates enhanced capability.

Q: What is the difference between R125252000 and R125256000?

A: Both parts are manufactured by Radiall USA, Inc., with identical electrical specifications and 250 V voltage ratings. The distinction is the flange mounting feature: R125252000 features a two-hole flange configuration, while R125256000 features a square flange configuration. Selection depends on panel mounting hole pattern requirements. Electrical performance is equivalent.

Q: Is the Rosenberger 32K401-271L5 compatible with applications designed for R125252000?

A: Yes. The 32K401-271L5 meets all mandatory electrical and mechanical parameters for SMA female socket connectors at 50 Ohms with solder termination. The extended operating temperature range (-65°C to 165°C) and higher voltage rating (480 V) provide additional performance margin. The part is suitable for applications with more demanding thermal or voltage requirements.

Q: Does packaging type (Box versus Bulk) affect connector performance?

A: No. Packaging type reflects supply chain and inventory management practices only. Box and Bulk packaging contain identical connectors with equivalent electrical and mechanical performance. Moisture sensitivity level differences (Not Applicable for Box packaging versus MSL 1 for Bulk packaging) indicate storage handling requirements but do not affect functional performance once installed.

Q: Can these connectors be used interchangeably in high-frequency RF applications?

A: Yes. All listed parts support frequencies up to 18 GHz with identical impedance (50 Ohms), dielectric material (PTFE), and center contact material (Beryllium Copper). Electrical performance in RF applications is equivalent across all substitute parts.

Q: What is the significance of the 500 mating cycle rating?

A: The 500 mating cycle specification indicates the connector is rated for 500 connection and disconnection cycles under normal operating conditions. This specification is identical across all listed parts, ensuring consistent mechanical durability and reliability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts are RoHS compliant. R125252000, 9431-1583-010, R125256000, and 32K401-271L5 are ROHS3 compliant. The 9441-1083-010 is RoHS compliant. All parts meet environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.
