Rosenberger 32K401-272L5 SMA Coaxial Connector - Equivalent & Substitute Parts

Part Overview

The Rosenberger 32K401-272L5 is an SMA connector jack (female socket) rated for 50 ohms impedance with panel mount solder termination. This connector is designed for RF applications up to 18 GHz and is currently in active product status with 618 units in stock. The part uses beryllium copper center contacts with gold plating and PTFE dielectric material, suitable for semi-rigid RG-402 cable applications. Equivalent substitute parts are available from multiple manufacturers to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Rosenberger 32K401-272L5 is determined by strict equivalence across the following critical 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-402 (.141" Semi Rigid)
• Fastening Type: Threaded
• Frequency - Max: 18 GHz
• Number of Ports: 1
• Center Contact Material: Beryllium Copper
• Dielectric Material: PTFE

All four substitute parts meet these mandatory parameters. Variations in body material (beryllium copper, stainless steel, or brass), body finish application, and operating temperature ranges do not affect functional equivalence within the specified electrical and mechanical constraints. Differences in product status, packaging format, and included components are noted but do not preclude substitution based on core RF performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): Amphenol RF 132110 and 132108, along with Cinch 142-0594-601, are recommended as primary substitutes. All three maintain active product status, ensuring long-term availability and manufacturer support. These parts carry ROHS3 compliance certification and demonstrate full electrical and mechanical equivalence to the Rosenberger 32K401-272L5 across all critical RF parameters.

Secondary Selection (Obsolete Status): TE Connectivity 1051081-1 is classified as obsolete and should be considered only when active alternatives are unavailable. While electrically equivalent, the obsolete status indicates discontinued manufacturing and potential supply constraints. The operating temperature range of -65°C to 125°C is narrower than the primary part specification of -65°C to 165°C, which may limit suitability in high-temperature applications.

Compliance Considerations: All substitute parts meet RoHS requirements. Amphenol RF parts (132108, 132110) and Cinch 142-0594-601 carry REACH Affected or REACH Unaffected designations, confirming regulatory compliance for European markets. The Rosenberger original part carries RoHS Compliant status without REACH specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Rosenberger 32K401-272L5 with any of the listed parts?

A: Yes. All four substitute parts meet the mandatory electrical and mechanical parameters: SMA connector style, 50 ohm impedance, solder termination, panel mount flange configuration, RG-402 cable compatibility, and 18 GHz frequency rating. Functional equivalence is confirmed across RF performance specifications.

Q: What is the difference between the Amphenol RF 132108 and 132110?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format (both supplied in bags) and inventory availability. Selection between these two should be based on procurement lead times and stock levels.

Q: Why is the TE Connectivity 1051081-1 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While the part remains electrically equivalent, future availability cannot be guaranteed. Additionally, the operating temperature range (-65°C to 125°C) is narrower than the original specification (-65°C to 165°C), which may restrict use in elevated temperature environments.

Q: Does the body material difference (beryllium copper vs. brass vs. stainless steel) affect RF performance?

A: No. Body material variations do not affect the core RF electrical characteristics specified for this connector category. All materials used across the substitute parts are standard for SMA connector construction and maintain the required impedance, frequency response, and signal integrity.

Q: Are there packaging differences I should consider?

A: Yes. The Amphenol RF parts (132108, 132110) include 3 pieces per package (1 connector, 1 contact, 1 insulator). The Rosenberger and Cinch parts do not specify included components. Verify packaging contents against your assembly requirements before procurement.

Q: Which substitute part has the best inventory availability?

A: Cinch 142-0594-601 has the highest stock level at 1183 units, followed by TE Connectivity 1051081-1 at 1004 units. For active products, Amphenol RF 132110 offers 979 units and 132108 offers 808 units. Rosenberger 32K401-272L5 has 618 units in stock.

Q: Can I use these connectors in applications requiring the full -65°C to 165°C temperature range?

A: The TE Connectivity 1051081-1 is limited to -65°C to 125°C and should not be used in applications requiring the full 165°C upper limit. All other substitute parts (Amphenol RF 132108, 132110, and Cinch 142-0594-601) support the complete -65°C to 165°C operating range equivalent to the original Rosenberger part.
