APH-SMAP-SMBJ Equivalent & Substitute Parts

Part Overview

The APH-SMAP-SMBJ is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Plug (Male Pin) and SMB Jack (Male Pin) configurations. This adapter operates at 50 Ohms impedance and supports frequencies up to 10 GHz with a straight, free-hanging (in-line) mounting style. The part is classified as Obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and ensure long-term component availability for new designs and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APH-SMAP-SMBJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Series: SMA to SMB
• Adapter Type: Plug to Jack
• Center Gender: Male to Male
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On, Threaded
• Body Material: Brass
• Body Finish: Gold
• Center Contact Material: Brass
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature Range: -65°C ~ 165°C

The substitute part 242144 satisfies all mandatory matching parameters. The primary distinction between the main part and its substitute is the maximum frequency specification and product status classification. The APH-SMAP-SMBJ operates at 10 GHz maximum frequency and is classified as Obsolete, while 242144 operates at 4 GHz maximum frequency and maintains Active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

For applications operating at frequencies up to 4 GHz: Part 242144 is the direct substitute for APH-SMAP-SMBJ. This part maintains identical mechanical and electrical characteristics across all critical parameters while offering the advantage of Active product status. Part 242144 is manufactured by Amphenol RF and carries ROHS3 compliance certification, exceeding the RoHS compliance level of the obsolete part. This substitute ensures continued supply chain access and compliance with current regulatory standards.

For applications requiring operation above 4 GHz up to 10 GHz: The APH-SMAP-SMBJ frequency specification of 10 GHz cannot be matched by the identified substitute part 242144, which is rated to 4 GHz maximum. In such cases, alternative component sourcing strategies or design modifications must be evaluated to accommodate the frequency requirement differential.

Compliance Considerations: Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4010. Part 242144 carries REACH Affected status, which must be evaluated against specific regulatory requirements for the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can part 242144 be used as a direct replacement for APH-SMAP-SMBJ in all applications?

A: Part 242144 is a direct mechanical and electrical substitute for applications operating at frequencies up to 4 GHz. Both parts share identical adapter series (SMA to SMB), center gender (Male to Male), impedance (50 Ohms), mounting style (Straight, Free Hanging), and material specifications. The primary limitation is the frequency rating: APH-SMAP-SMBJ supports 10 GHz while 242144 supports 4 GHz. Applications requiring operation above 4 GHz require alternative component selection.

Q: What is the significance of the product status difference between these parts?

A: APH-SMAP-SMBJ is classified as Obsolete, indicating discontinued manufacturing and limited availability. Part 242144 is classified as Active, indicating current production and ongoing manufacturer support. For new designs and long-term production requirements, part 242144 provides supply chain continuity and access to current manufacturing quality standards.

Q: Are there packaging differences between these parts?

A: APH-SMAP-SMBJ packaging is not specified in the available data. Part 242144 is supplied in Bag packaging. Packaging differences do not affect functional compatibility but may impact inventory management and handling procedures.

Q: How do the RoHS compliance levels differ?

A: APH-SMAP-SMBJ carries RoHS Compliant certification. Part 242144 carries ROHS3 Compliant certification, which represents a more current regulatory standard. Both parts satisfy RoHS requirements; ROHS3 compliance indicates alignment with the most recent directive version.

Q: What does REACH Affected status mean for part 242144?

A: REACH Affected status indicates that part 242144 is subject to the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. This status requires evaluation against specific regulatory requirements for the end application and geographic market of use. Compliance verification is necessary for applications in regulated markets.

Q: Are the operating temperature ranges identical?

A: Both parts operate across the identical temperature range of -65°C to 165°C. This parameter is fully equivalent between the main part and substitute.

Q: What is the significance of MSL Level 1 (Unlimited)?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that both parts have no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or shipping, simplifying logistics and inventory management.
