Amphenol RF 132343 SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 132343 is an SMA connector jack, female socket, rated for 50 ohms impedance with board edge end launch solder termination. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. The connector operates across a frequency range up to 18 GHz with an operating temperature range of -65°C to 165°C and supports 500 mating cycles. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within the same connector category.

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 132343 are classified into two categories based on parametric alignment:

Parametric Equivalents maintain all critical electrical and mechanical specifications: SMA connector style, jack female socket configuration, 50 ohm impedance, board edge end launch mounting, solder termination, threaded fastening, 18 GHz maximum frequency, -65°C to 165°C operating temperature range, 500 mating cycles, beryllium copper center contact, brass body with gold finish, PTFE dielectric, and MSL 1 rating. These parts are direct functional replacements.

Similar Parts share the core connector category and primary electrical specifications (50 ohm impedance, board edge mounting, solder termination) but differ in one or more secondary parameters such as connector style (SMB versus SMA), contact material composition, body finish (nickel versus gold), or frequency rating. These parts provide functional alternatives when parametric equivalents are unavailable.

The following parameters determine substitution eligibility:

Connector Style (SMA primary requirement)
Connector Type (Jack, Female Socket primary requirement)
Impedance (50 Ohms)
Mounting Type (Board Edge, End Launch)
Contact Termination (Solder)
Shield Termination (Solder)
Fastening Type (Threaded)
Frequency - Max (18 GHz minimum)
Operating Temperature Range (-65°C ~ 165°C)
Mating Cycles (500)

Engineering Selection Recommendations

Primary Equivalent Selection:

Amphenol RF 901-10019 is the primary parametric equivalent to the obsolete 132343. Both parts are manufactured by Amphenol RF and maintain identical electrical and mechanical specifications across all critical parameters. The 901-10019 is active in production status and carries ROHS3 compliance, providing enhanced regulatory alignment compared to the original RoHS Compliant designation of the 132343.

Secondary Equivalent Options:

Cinch Connectivity Solutions 142-1701-851 and 142-1701-871 are parametric equivalents with active product status and ROHS3 compliance. Both maintain full specification alignment with the 132343 across connector style, impedance, mounting configuration, and frequency rating. The 142-1701-841 variant is also available with RoHS Compliant status.

Molex 0732511151 is a parametric equivalent with active status and ROHS3 compliance. This part maintains identical specifications and provides an alternative from a different established manufacturer.

Alternative Consideration:

TE Connectivity Linx CONSMA003.031 and CONSMA003.062 are functionally compatible alternatives with active status. These parts differ in body finish (nickel versus gold) and connector type designation (receptacle versus jack), though both provide female socket configuration. The CONSMA003.062 offers higher inventory availability in bulk packaging.

Non-Recommended Substitution:

Cinch Connectivity Solutions 131-3701-811 is classified as a similar part rather than an equivalent. This SMB connector differs in connector style, contact type (male pin versus female socket), fastening mechanism (snap-on versus threaded), and maximum frequency (4 GHz versus 18 GHz). This part is suitable only when SMB connector specifications are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 901-10019 directly replace the obsolete 132343?

A: Yes. The 901-10019 is a parametric equivalent with identical specifications across all critical parameters: SMA connector style, jack female socket configuration, 50 ohm impedance, board edge end launch mounting, solder termination, threaded fastening, 18 GHz frequency rating, -65°C to 165°C operating temperature, and 500 mating cycles. The 901-10019 is active in production and carries ROHS3 compliance.

Q: What is the difference between "Jack" and "Receptacle" connector types in the substitute list?

A: Both designations refer to female socket configurations in SMA connectors. The terminology difference reflects manufacturer nomenclature conventions. Functionally, both accept male pin connectors. The TE Connectivity Linx parts (CONSMA003.031 and CONSMA003.062) use "receptacle" terminology while Amphenol RF and Cinch use "jack" terminology for equivalent female socket configurations.

Q: Why does the TE Connectivity Linx CONSMA003.062 have a nickel body finish instead of gold?

A: The CONSMA003.062 features a nickel body finish with gold-plated center contact, while the 132343 has a gold body finish. Both finishes provide equivalent corrosion resistance and electrical performance at 50 ohm impedance. The nickel finish is a manufacturing variation that does not affect electrical compatibility or frequency response up to 18 GHz.

Q: Are the Cinch Connectivity Solutions 142-1701-841, 142-1701-851, and 142-1701-871 interchangeable?

A: Yes. All three Cinch parts (142-1701-841, 142-1701-851, and 142-1701-871) are parametric equivalents with identical electrical and mechanical specifications. The numerical suffix variation indicates manufacturing or packaging differences. The 142-1701-851 and 142-1701-871 carry ROHS3 compliance, while the 142-1701-841 carries RoHS Compliant status.

Q: Can the SMB connector 131-3701-811 be used as a substitute for the SMA 132343?

A: No. The 131-3701-811 is not a suitable substitute. This part differs in multiple critical parameters: connector style (SMB versus SMA), contact type (male pin versus female socket), fastening mechanism (snap-on versus threaded), and maximum frequency (4 GHz versus 18 GHz). Substitution would require circuit redesign and is not recommended for direct replacement applications.

Q: What packaging options are available for equivalent parts?

A: The Amphenol RF 901-10019 is supplied in bulk packaging. Cinch Connectivity Solutions parts (142-1701-841, 142-1701-851, 142-1701-871, and 142-0701-881) are supplied in bulk packaging. Molex 0732511151 is supplied in bulk packaging. TE Connectivity Linx CONSMA003.031 is supplied in tray packaging, while CONSMA003.062 is supplied in bulk packaging. Selection should account for assembly process requirements and inventory management protocols.

Q: Are all substitute parts RoHS compliant?

A: The original 132343 carries RoHS Compliant status. Most active equivalents carry ROHS3 Compliant status, which represents enhanced regulatory compliance. The TE Connectivity Linx parts (CONSMA003.031 and CONSMA003.062) carry RoHS Compliant status. All listed parts meet RoHS requirements; ROHS3 designation indicates compliance with the most current regulatory standard.

Q: What is the inventory status for equivalent parts?

A: Amphenol RF 901-10019 has 1,175 pieces in stock. Cinch Connectivity Solutions 142-0701-881 has 3,866 pieces in stock. Cinch 142-1701-851 has 1,195 pieces in stock.
