The Hirose Electric Co Ltd part BNC-J-1.5CR(40) qualifies as a substitute based on matching all core electrical and mechanical parameters. However, the following parameter differences must be evaluated for specific applications:

• Shield Termination: Clamp (031-15) versus Crimp (BNC-J-1.5CR(40))
• Frequency - Max: 4 GHz (031-15) versus 1 GHz (BNC-J-1.5CR(40))
• Operating Temperature: -65°C ~ 165°C (031-15) versus -30°C ~ 60°C (BNC-J-1.5CR(40))
• Cable Group: RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209 (031-15) versus 1.5C-2V, 1.5D-2V (BNC-J-1.5CR(40))

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (Amphenol RF 031-15): The Amphenol RF 031-15 is the specified component for applications requiring maximum frequency operation to 4 GHz, extended operating temperature range (-65°C to 165°C), and compatibility with standard RG-59 series coaxial cables. This part maintains ROHS3 compliance and is suitable for demanding RF environments.

Substitute Part Selection (Hirose BNC-J-1.5CR(40)): The Hirose Electric Co Ltd BNC-J-1.5CR(40) is electrically and mechanically compatible for applications operating at frequencies up to 1 GHz within the operating temperature range of -30°C to 60°C. This substitute is suitable for lower-frequency RF applications and standard environmental conditions. The crimp shield termination differs from the clamp termination of the primary part and requires compatibility with 1.5C-2V or 1.5D-2V cable specifications.

Both parts maintain equivalent RoHS compliance, MSL rating, and ECCN classification, supporting regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Hirose BNC-J-1.5CR(40) replace the Amphenol RF 031-15 in all applications?

A: No. The Hirose substitute is limited to applications operating at frequencies up to 1 GHz, compared to the Amphenol part's 4 GHz maximum frequency. Additionally, the operating temperature range is restricted to -30°C to 60°C versus -65°C to 165°C for the primary part. Substitution is valid only when application requirements fall within these parameter boundaries.

Q: What is the difference between clamp and crimp shield termination?

A: The Amphenol RF 031-15 uses clamp shield termination, while the Hirose BNC-J-1.5CR(40) uses crimp termination. These represent different mechanical methods for securing the cable shield to the connector body. Clamp termination uses a mechanical clamping mechanism, whereas crimp termination requires a crimping tool to compress the termination onto the cable. Cable compatibility specifications differ between these termination types.

Q: Are both parts RoHS compliant?

A: Yes. The Amphenol RF 031-15 is ROHS3 compliant, and the Hirose BNC-J-1.5CR(40) is RoHS compliant. Both parts meet regulatory requirements for hazardous substance restrictions.

Q: What cable types are compatible with each part?

A: The Amphenol RF 031-15 is compatible with RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, and 9209 cable series. The Hirose BNC-J-1.5CR(40) is compatible with 1.5C-2V and 1.5D-2V cable specifications. Cable group compatibility must be verified before substitution.

Q: Do both parts have the same mating cycle rating?

A: Yes. Both the Amphenol RF 031-15 and Hirose BNC-J-1.5CR(40) are rated for 500 mating cycles, providing equivalent mechanical durability for connector engagement and disengagement operations.

Q: What is the insertion loss specification for the Hirose substitute?

A: The insertion loss specification for the Hirose BNC-J-1.5CR(40) is not provided in the available technical data. The Amphenol RF 031-15 specifies 0.2 dB insertion loss. Insertion loss performance of the Hirose part must be obtained from the manufacturer if this parameter is critical for the application.
