Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-1337548-0 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following core substitution criteria:

Matching Parameters:

• Connector Style: BNC (identical)
• Connector Type: Jack, Female Socket (identical)
• Mounting Type: Panel Mount (identical)
• Mounting Feature: Bulkhead - Front Side Nut (identical)
• Fastening Type: Bayonet Lock (identical)
• Number of Ports: 1 (identical)
• Product Status: Active (both current production)

Termination Difference: The substitute part uses solder termination for the contact, whereas the main part uses crimp termination. Both shield terminations are crimp. This difference affects assembly methodology but does not prevent functional equivalence in applications where solder termination is acceptable.

Cable Compatibility: The substitute supports RG-174A, 188A, and 316 cable groups, which include RG-174 compatibility, ensuring mechanical and electrical fit with the intended cable specifications.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and identical export classification (ECCN: EAR99, HTSUS: 8536.69.4010), ensuring regulatory consistency. The substitute part 1-1337548-0 provides additional technical specifications including 50 Ohm impedance rating, 4 GHz maximum frequency, and extended operating temperature range (-65°C to 165°C), which may be advantageous for RF applications requiring impedance matching and thermal stability. The substitute also includes RoHS3 compliance and REACH affected status documentation.

Selection between crimp and solder termination should be based on assembly process requirements and equipment availability. Both termination methods are industry-standard for BNC connectors in this class.

Frequently Asked Questions (FAQ)

Q: Can 1-1337548-0 directly replace VB40-2072 in existing designs?

A: Yes, provided the assembly process accommodates solder termination instead of crimp termination. Both connectors share identical mechanical mounting, bayonet fastening, and panel mount configuration. Cable compatibility is maintained through RG-174 support in the substitute part.

Q: What is the primary difference between these two parts?

A: The main difference is contact termination method. VB40-2072 uses crimp termination, while 1-1337548-0 uses solder termination. Shield termination is crimp for both parts. This affects assembly methodology but not electrical performance in equivalent applications.

Q: Does the 50 Ohm impedance specification of 1-1337548-0 affect compatibility?

A: The VB40-2072 does not specify impedance in the provided data. The 50 Ohm rating of 1-1337548-0 is standard for BNC connectors in RF applications. If the application requires impedance matching, the substitute part's explicit 50 Ohm specification provides documented performance.

Q: Are there packaging or quantity considerations?

A: VB40-2072 is available in bulk packaging with 949 pieces in stock. The substitute 1-1337548-0 is also bulk packaged with 3321 pieces in stock. The substitute includes 8 component pieces per connector unit (contact, ferrule, gasket, insulator, lockwasher, nut, sleeve).

Q: What compliance certifications apply to the substitute part?

A: The substitute part 1-1337548-0 is RoHS3 compliant and REACH affected. Both parts share identical ECCN and HTSUS classifications for export purposes.
