• Connector Type: Plug, Male Pin
• Mounting Type: Free Hanging (In-Line)
• Body Material: Stainless Steel
• Fastening Type: Threaded
• Number of Ports: 1
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS Code: 8536.69.4010

The 147-0801-801 maintains mechanical and electrical compatibility through identical connector geometry and interface specifications. Both components are designed for 2.4mm coaxial applications with threaded fastening and free-hanging mounting configurations.

Parameter Comparison

Engineering Selection Recommendations

The 147-0801-801 from Cinch Connectivity Solutions is the designated substitute for the obsolete CS-DM-MJB. Selection is based on:

Product Status: The CS-DM-MJB is obsolete, while 147-0801-801 maintains active production status with 996 units in current inventory, ensuring long-term availability and supply chain continuity.

Compliance Posture: The 147-0801-801 carries ROHS3 compliance certification, meeting modern regulatory requirements. The CS-DM-MJB does not specify RoHS status. Both components share identical ECCN (EAR99) and HTSUS classifications, maintaining consistent export and tariff treatment.

Regulatory Alignment: The 147-0801-801 is REACH Affected, indicating compliance with current European chemical regulations. The CS-DM-MJB is REACH Unaffected, reflecting its obsolete status and lack of current regulatory oversight.

Mechanical Compatibility: Both connectors maintain identical 2.4mm (APC-2.4, OS-50) geometry, threaded fastening, and free-hanging mounting specifications, ensuring direct mechanical interchangeability in existing installations.

Frequently Asked Questions (FAQ)

Q: Can 147-0801-801 directly replace CS-DM-MJB in existing assemblies?

A: Yes. Both components share identical connector geometry (2.4mm APC-2.4, OS-50), fastening type (threaded), and mounting configuration (free-hanging in-line). Mechanical and electrical interfaces are fully compatible.

Q: What are the key differences between these two parts?

A: The primary differences are product status (CS-DM-MJB is obsolete; 147-0801-801 is active), dielectric material composition (PPO/PS versus PEEK), and regulatory certifications. The 147-0801-801 includes ROHS3 compliance and specifies maximum frequency capability at 50 GHz.

Q: Does the change in dielectric material affect performance?

A: Dielectric material differences are provided in the specifications. Both materials are suitable for 2.4mm coaxial connector applications. Specific performance requirements should be evaluated against application parameters.

Q: What is the packaging difference?

A: CS-DM-MJB is supplied in standard packaging; 147-0801-801 is supplied in bulk packaging. Bulk packaging typically accommodates higher-volume procurement requirements.

Q: Are there any compliance concerns with substitution?

A: The 147-0801-801 meets current regulatory standards (ROHS3, REACH Affected) and maintains identical export classification (EAR99). No compliance barriers exist for substitution in applications requiring modern regulatory alignment.

Q: Why is inventory availability important for this substitution?

A: The CS-DM-MJB is obsolete with limited remaining stock (765 units). The 147-0801-801 is in active production with 996 units currently available, ensuring reliable long-term component sourcing for ongoing system support and future production runs.
