APH-SMAJ-NP Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-NP is a coaxial connector adapter manufactured by Amphenol RF, designed to convert between SMA Jack (Female Socket) and N Plug (Male Pin) connectors. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz and supports operating temperatures from -65°C to 165°C.

The APH-SMAJ-NP is classified as an obsolete product. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA to N series conversion in RF and microwave systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APH-SMAJ-NP must satisfy the following criteria to ensure functional equivalence:

Critical Substitution Parameters:

• Adapter Series: SMA to N conversion capability
• Center Gender: Female to Male conversion
• Impedance: 50 Ohms
• Frequency Rating: Minimum 11 GHz
• Operating Temperature Range: -65°C to 165°C
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded connections

The substitute part 242113 meets all critical parameters. While the APH-SMAJ-NP converts from SMA Jack to N Plug, the 242113 converts from N Plug to SMA Jack. Both parts provide bidirectional SMA-to-N series conversion with identical electrical and mechanical specifications, making them functionally interchangeable in applications requiring this connector pairing.

Engineering Selection Recommendations

Primary Substitute: 242113

The part 242113 is the recommended substitute for the obsolete APH-SMAJ-NP. Selection rationale is based on the following factors:

Product Status: The 242113 is classified as Active, ensuring ongoing availability and manufacturing support. The APH-SMAJ-NP is Obsolete, making 242113 the appropriate choice for new designs and replacement applications.

Compliance Certifications: Both parts maintain RoHS compliance. The 242113 carries ROHS3 Compliant status, representing the current regulatory standard. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4010, confirming equivalent export and tariff classifications.

Electrical and Mechanical Equivalence: All critical parameters are identical between the two parts, including impedance (50 Ohms), frequency rating (11 GHz), operating temperature range (-65°C to 165°C), and connector specifications. The parts are manufactured from identical materials with matching plating and dielectric properties.

Inventory Availability: The 242113 has 2218 pieces in stock, compared to 1155 pieces for the APH-SMAJ-NP, providing superior supply continuity.

Connector Orientation: While the APH-SMAJ-NP converts from SMA Jack to N Plug and the 242113 converts from N Plug to SMA Jack, both parts provide the same functional SMA-to-N series conversion capability and are interchangeable in applications requiring this adapter type.

Frequently Asked Questions (FAQ)

Q: Can the 242113 directly replace the APH-SMAJ-NP in existing applications?

A: Yes. Both parts provide SMA-to-N series conversion with identical electrical specifications (50 Ohms, 11 GHz maximum frequency), mechanical construction, and operating temperature range. The connector orientation difference (which end is SMA versus N) does not affect functional equivalence in adapter applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: adapter series (SMA to N), center gender (Female to Male), impedance (50 Ohms), frequency rating (minimum 11 GHz), operating temperature range (-65°C to 165°C), mounting type (Free Hanging In-Line), and fastening type (Threaded). The 242113 matches all these parameters.

Q: Why is the 242113 preferred over the APH-SMAJ-NP?

A: The 242113 is preferred because it is classified as Active, ensuring continued manufacturing and supply availability. The APH-SMAJ-NP is Obsolete. Additionally, the 242113 carries ROHS3 Compliant status, representing current regulatory standards, and has greater inventory availability.

Q: Are there packaging differences between these parts?

A: The APH-SMAJ-NP packaging is not specified in the available data. The 242113 is packaged in Bag format. Packaging differences do not affect electrical or mechanical performance.

Q: Do both parts meet current compliance requirements?

A: Yes. Both parts are RoHS compliant. The 242113 carries ROHS3 Compliant status. The 242113 is also REACH Affected. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: What is the maximum operating frequency for these adapters?

A: Both the APH-SMAJ-NP and 242113 are rated for a maximum frequency of 11 GHz, making them suitable for RF and microwave applications within this frequency range.

Q: Are the materials and plating specifications identical?

A: Yes. Both parts use brass bodies with nickel finish, phosphor bronze center contacts with gold plating, and PTFE dielectric material. These specifications are identical across both parts.
