Greenlee Communications 45732 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Greenlee Communications 45732 is a BNC connector plug designed for coaxial cable termination in RF applications. This male pin, free hanging (in-line) crimp connector is used in systems requiring 50-ohm impedance matching and bayonet-lock mating. The part is currently in stock with 912 units available as new original inventory.

Substitute parts are identified based on matching electrical characteristics (50-ohm impedance, frequency rating, voltage specification) and mechanical compatibility (BNC plug configuration, crimp termination, free hanging mounting, bayonet lock fastening).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Greenlee Communications 45732 is determined by the following critical parameters:

Electrical Compatibility:

• Impedance: 50 Ohms (required match)
• Frequency rating: 2 GHz maximum (substitute must meet or exceed)
• Voltage rating: 500 V (substitute must meet or exceed)

Mechanical Compatibility:

• Connector style: BNC (exact match required)
• Connector type: Plug, Male Pin (exact match required)
• Contact termination: Crimp (exact match required)
• Shield termination: Crimp (exact match required)
• Mounting type: Free Hanging (In-Line) (exact match required)
• Fastening type: Bayonet Lock (exact match required)

Cable Compatibility:

• Supported cable groups: RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209

The Amphenol RF 68175 meets all critical electrical and mechanical parameters and is classified as a direct substitute.

Engineering Selection Recommendations

Primary Selection: Greenlee Communications 45732

The Greenlee 45732 is the specified component with confirmed inventory availability (912 units). Use this part for new applications and existing designs where the original specification is maintained.

Substitute Selection: Amphenol RF 68175

The Amphenol RF 68175 is a direct electrical and mechanical equivalent. This substitute is applicable when:

• Greenlee 45732 inventory is unavailable
• Design flexibility permits manufacturer substitution
• ROHS3 compliance is required (Amphenol 68175 is ROHS3 compliant)
• Operating conditions fall within the specified ranges (-65°C ~ 165°C, 500 V, 2 GHz maximum frequency)

Product Status Consideration:

The Amphenol RF 68175 carries a "Not For New Designs" status. This designation indicates the part is available for existing applications and legacy system support but should not be selected for new product development unless no alternative exists. For new designs, evaluate current-generation BNC connector offerings from both manufacturers.

Compliance and Certifications:

The Amphenol RF 68175 is ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 68175 be used as a direct replacement for the Greenlee 45732?

A: Yes. Both connectors share identical electrical specifications (50-ohm impedance, 500 V rating, 2 GHz frequency capability) and mechanical configuration (BNC plug, male pin, crimp termination, free hanging mounting, bayonet lock). The connectors are mechanically and electrically interchangeable for the specified cable groups (RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209).

Q: What does "Not For New Designs" mean for the Amphenol RF 68175?

A: This product status indicates the part is in production and available for purchase but is not recommended for incorporation into new product designs. The designation typically reflects manufacturer lifecycle management. For new designs, contact the manufacturer for current-generation alternatives or confirm design flexibility permits use of legacy components.

Q: Are there packaging differences between these parts?

A: The Greenlee 45732 packaging specification is not provided in the technical data. The Amphenol RF 68175 is supplied in bulk packaging. Confirm packaging requirements with your procurement department before substitution.

Q: What cable types are compatible with these connectors?

A: Both connectors support the following cable groups: RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209. Verify your specific cable type matches this list before connector selection.

Q: What is the mating cycle rating?

A: The Amphenol RF 68175 is rated for 500 mating cycles. This specification is not provided for the Greenlee 45732. For applications requiring higher cycle counts, consult manufacturer datasheets.

Q: Is the Amphenol RF 68175 RoHS compliant?

A: Yes. The Amphenol RF 68175 is ROHS3 compliant with a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture sensitivity restrictions.

Q: What is the insertion loss specification?

A: The Amphenol RF 68175 specifies 0.2 dB insertion loss. This specification is not provided for the Greenlee 45732. For RF applications requiring low-loss performance, the Amphenol specification provides a reference baseline.
