Key Parameters

Substitute Part Grouping Explanation

Substitution of the 031-80107 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Cable Group: RG-179, 179A, 179B, 187, 187A, Belden 9221, M17/94-RG179
• Voltage Rating: 500 V
• Mating Cycles: 500

Secondary Considerations:

• Packaging format (Bulk vs. Bag)
• Body material composition
• Dielectric material type
• Operating temperature range
• Product status (Active vs. Not For New Designs)

All substitute parts listed maintain full electrical and mechanical compatibility with the 031-80107 across the primary criteria. Variations in secondary parameters are noted in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 031-70013

The 031-70013 is the preferred substitute for the 031-80107. Both parts are classified as Active product status and maintain identical electrical specifications including 75-ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, and 500 mating cycles. Both feature PTFE dielectric material and operate across the full temperature range of -65°C to 165°C. The 031-70013 is available in Bulk packaging and carries ROHS3 compliance. The primary difference is body material composition (Brass vs. Phosphor Bronze), which does not affect electrical performance or mechanical compatibility.

Secondary Recommendations: 112133 and 112954

The 112133 and 112954 are functionally equivalent substitutes with Active and Not For New Designs status respectively. Both maintain all critical electrical parameters and cable compatibility. These parts are packaged in Bag format rather than Bulk. The 112133 uses POM Acetal dielectric material, while 112954 uses PTFE. Operating temperature specifications are not provided for 112954 and are unspecified for 112133.

Not Recommended for New Designs: 112139

The 112139 carries a "Not For New Designs" product status designation. While electrically equivalent, this part features a reduced operating temperature range of -55°C to 85°C compared to the 031-80107's -65°C to 165°C specification. This part should be used only for legacy system maintenance or replacement applications where the original design specified this component.

Compliance Considerations

All substitute parts maintain ROHS3 compliance, REACH affected status, and MSL 1 (Unlimited) moisture sensitivity level, ensuring regulatory equivalence with the 031-80107.

Frequently Asked Questions (FAQ)

Q: Can I substitute 031-70013 for 031-80107 in existing designs?

A: Yes. The 031-70013 maintains full electrical and mechanical compatibility with the 031-80107 across all critical parameters including impedance, frequency response, voltage rating, and cable compatibility. Both parts are Active status and ROHS3 compliant. The primary difference is body material (Brass vs. Phosphor Bronze), which does not affect connector performance.

Q: What is the difference between Bulk and Bag packaging?

A: Packaging format does not affect electrical or mechanical performance. The 031-80107 and 031-70013 are supplied in Bulk packaging, while 112133, 112139, and 112954 are supplied in Bag packaging. Selection between these formats depends on procurement and inventory management requirements.

Q: Why is 112139 marked "Not For New Designs"?

A: The 112139 carries this designation due to its reduced operating temperature range of -55°C to 85°C compared to the standard -65°C to 165°C specification. This part should be used only for replacement or maintenance of existing systems that originally specified this component. New designs should use Active status parts such as 031-80107, 031-70013, or 112133.

Q: Are all substitute parts compatible with RG-179 and RG-187 cable groups?

A: Yes. All substitute parts listed are compatible with the same cable group: RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179. Cable compatibility is maintained across all substitutes.

Q: What is the significance of dielectric material differences (PTFE vs. POM Acetal)?

A: Both PTFE and POM Acetal are acceptable dielectric materials for 75-ohm BNC connectors operating at the specified frequency and voltage ratings. The 031-80107 and 031-70013 use PTFE, while 112133 uses POM Acetal. Both materials meet the electrical requirements for this application. Material selection may be driven by specific environmental or manufacturing requirements.

Q: Can I use 112954 in applications requiring the full -65°C to 165°C temperature range?

A: The 112954 does not specify an operating temperature range in the provided data. For applications requiring the full -65°C to 165°C temperature range, use 031-80107 or 031-70013, both of which explicitly specify this range.

Q: Are all parts RoHS3 compliant?

A: Yes. All substitute parts listed (031-70013, 112133, 112139, and 112954) are ROHS3 compliant, matching the compliance status of the 031-80107.
