Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1337427-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Cable Group Compatibility: RG-58C, 141A, Belden 9907
• Frequency - Max: 4 GHz
• Operating Temperature Range: -65°C to 165°C
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Number of Ports: 1

Allowable Variation Parameters:

• Contact Termination: Solder or Crimp (both acceptable for RF coaxial connector applications)

Parameter Comparison

Engineering Selection Recommendations

Both the main part 1-1337427-0 and substitute part 1-1337426-0 are classified as obsolete products. Selection between these parts is based on the following engineering criteria:

Primary Selection Criteria:

1. Termination Method Requirement: The main part 1-1337427-0 features solder contact termination, while the substitute 1-1337426-0 features crimp contact termination. Selection depends on the cable assembly method specified in the application design. Solder termination is appropriate for applications requiring permanent connections, while crimp termination is suitable for field-replaceable or modular cable assemblies.

2. Compliance Status: Both parts maintain RoHS Compliant certification, ensuring regulatory compliance for applications subject to RoHS directives. The main part 1-1337427-0 carries REACH Affected status, while the substitute part 1-1337426-0 carries Vendor Undefined REACH status. Applications requiring confirmed REACH compliance documentation should reference the main part specification.

3. Inventory Availability: The main part 1-1337427-0 has 2300 pieces in stock, while the substitute part 1-1337426-0 has 2400 pieces in stock. Both are available as new original components.

4. Plating and Finish Variations: The main part features silver body finish with silver center contact plating. The substitute part features nickel body finish with gold center contact plating. Both finishes provide equivalent RF performance and electrical continuity for 50-ohm coaxial applications.

Frequently Asked Questions (FAQ)

Q: Can 1-1337426-0 be used as a direct replacement for 1-1337427-0?

A: The 1-1337426-0 is a valid substitute for 1-1337427-0 in applications where the contact termination method can be changed from solder to crimp. All RF electrical parameters, impedance characteristics, frequency response, and mechanical mounting specifications are equivalent. The primary difference is the termination method, which must be compatible with the cable assembly process specified in the application.

Q: What is the difference between solder and crimp termination in these BNC connectors?

A: Solder termination (1-1337427-0) creates a permanent connection through soldering the center contact and shield to the cable. Crimp termination (1-1337426-0) uses mechanical compression to secure the contact and shield to the cable. Both methods achieve equivalent electrical performance when properly executed. Selection depends on whether the application requires permanent assembly or field-replaceable connections.

Q: Are the plating differences between these parts significant?

A: The main part 1-1337427-0 features silver body finish with silver center contact plating. The substitute part 1-1337426-0 features nickel body finish with gold center contact plating. Both plating systems provide equivalent RF performance, electrical conductivity, and corrosion resistance for 50-ohm coaxial connector applications. Plating selection does not affect impedance, insertion loss, or frequency response.

Q: Do both parts support the same cable types?

A: Yes. Both 1-1337427-0 and 1-1337426-0 are compatible with RG-58C, 141A, and Belden 9907 cable groups. The cable compatibility is determined by the connector's mechanical design and impedance rating, which are identical between the two parts.

Q: What is the maximum frequency rating for these connectors?

A: Both parts are rated for maximum frequency of 4 GHz. This rating applies to the RF transmission characteristics and is consistent across both the main part and substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both 1-1337427-0 and 1-1337426-0 are RoHS Compliant. The main part carries REACH Affected status, while the substitute part carries Vendor Undefined REACH status. Applications requiring specific REACH compliance documentation should reference the main part specification.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the temperature range of -65°C to 165°C. This range is identical for 1-1337427-0 and 1-1337426-0.

Q: How many mating cycles are these connectors rated for?

A: Both parts are rated for 500 mating cycles. This specification applies to the bayonet lock fastening mechanism and is equivalent across both the main part and substitute part.
