Rosenberger 144810 SMA Bulkhead Jack Coaxial Connector Equivalent & Substitute Parts

Part Overview

The Rosenberger 144810 is an SMA bulkhead jack connector designed for RF coaxial applications requiring 50 Ohm impedance. This female socket connector features panel mount installation with solder termination for both center contact and shield. The connector is rated for operation up to 18 GHz and accommodates RG-405 semi-rigid cable (.085" diameter). The part is currently active in production with 650 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when design specifications allow for compatible alternatives that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Rosenberger 144810 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector style (SMA)
• Connector type (Jack, Female Socket)
• Impedance (50 Ohms)
• Frequency rating (18 GHz maximum)

Mechanical Parameters:

• Mounting type (Panel Mount)
• Mounting feature (Bulkhead - Front Side Nut)
• Cable group compatibility (RG-405, .085" semi-rigid)
• Fastening type (Threaded)
• Termination method (Solder for both center contact and shield)

Material & Environmental Parameters:

• Center contact material (Beryllium Copper)
• Dielectric material (Polytetrafluoroethylene/PTFE)
• Operating temperature range
• Voltage rating
• Mating cycles

All substitute parts listed maintain equivalence across these core parameters. Variations in body material, body finish, voltage rating, operating temperature range, and product status are noted but do not preclude substitution when the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - Rosenberger 144810: The Rosenberger 144810 remains the preferred choice when available. It is currently active in production, ROHS3 compliant, and offers the highest operating temperature range (-65°C to 165°C) and voltage rating (480 V) among all equivalent options.

Secondary Selection - Radiall 9453-1583-010: This part is recommended as the first substitute when the Rosenberger 144810 is unavailable. It maintains full electrical and mechanical equivalence, is currently active in production, and has the highest inventory availability (1112 units). It includes mounting hardware (lockwasher and nut) as standard. ROHS3 compliance status is not applicable for this part.

Tertiary Selection - Radiall 9453-1083-010: This part is equivalent to the 9453-1583-010 and serves as an alternative Radiall option. It is ROHS3 compliant and currently active in production with 824 units in stock. It also includes mounting hardware as standard.

Quaternary Selection - Radiall R125326000W: This part is equivalent across all critical electrical and mechanical parameters and is ROHS3 compliant. It is currently active in production with 766 units in stock. The packaging format differs (Box versus Bulk), and the voltage rating is lower (250 V) compared to other options.

Not Recommended - TE Connectivity 2101520-1: While this part maintains electrical and mechanical equivalence, it is discontinued at DiGi Electronics and therefore not suitable for new designs or long-term supply chain planning. The operating temperature range is also limited to -65°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the Radiall 9453-1583-010 be used as a direct replacement for the Rosenberger 144810?

A: Yes. Both connectors are electrically and mechanically equivalent SMA bulkhead jack connectors with 50 Ohm impedance, 18 GHz frequency rating, and RG-405 cable compatibility. The primary differences are manufacturer, body material composition, and voltage rating. The Radiall part is suitable for applications where the operating voltage does not exceed 350 V.

Q: What is the difference between Radiall 9453-1583-010 and 9453-1083-010?

A: Both parts are functionally equivalent SMA bulkhead jack connectors with identical electrical specifications, mechanical configuration, and operating temperature range. Both include mounting hardware (lockwasher and nut) as standard. The primary difference is RoHS compliance status: the 9453-1083-010 is ROHS3 compliant, while the 9453-1583-010 has not applicable RoHS status.

Q: Why does the Rosenberger 144810 have a higher operating temperature range than the substitute parts?

A: The operating temperature range is determined by the connector design and material composition. The Rosenberger 144810 is rated for -65°C to 165°C, while the Radiall and TE Connectivity alternatives are rated for -65°C to 105°C. This difference does not affect substitution eligibility but should be considered for applications requiring operation above 105°C.

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

A: No. Packaging format affects only handling, storage, and inventory management. The Radiall R125326000W is supplied in Box packaging while other options are supplied in Bulk packaging. The connector itself is identical regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: No. The Rosenberger 144810, TE Connectivity 2101520-1, Radiall 9453-1083-010, and Radiall R125326000W are ROHS3 compliant. The Radiall 9453-1583-010 has not applicable RoHS status. For applications requiring ROHS3 compliance, select from the compliant options.

Q: What is the significance of the 500 mating cycles specification?

A: The 500 mating cycles specification indicates the connector is rated for 500 connect/disconnect cycles before performance degradation. The Rosenberger 144810, Radiall 9453-1083-010, Radiall 9453-1583-010, and Radiall R125326000W all meet this specification. The TE Connectivity 2101520-1 does not specify mating cycles.

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

A: Yes, provided the application requirements fall within the electrical and mechanical specifications of the substitute part. Critical considerations include operating voltage (ensure it does not exceed the substitute part's voltage rating), operating temperature (ensure it remains within the substitute part's temperature range), and any specific compliance requirements (such as ROHS3 certification).

Q: Why is the TE Connectivity 2101520-1 listed as discontinued?

A: The TE Connectivity 2101520-1 is discontinued at DiGi Electronics, indicating it is no longer actively distributed through this major electronics supplier. While inventory may still be available from other sources, this status makes it unsuitable for new designs or applications requiring long-term supply chain stability.
