Key Parameters

Substitute Part Grouping Explanation

The 3CV-P2(40) qualifies as a parametric equivalent to BNC-P-3(40) based on the following critical substitution criteria:

Matching Parameters (Substitution Basis):

• Connector style: BNC
• Connector type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact termination: Solder
• Shield termination: Clamp
• Mounting type: Free Hanging (In-Line)
• Fastening type: Bayonet Lock
• Frequency maximum: 4 GHz
• Cable group: 3C-2V
• Center contact material: Brass
• Body material: Brass
• Dielectric material: PTFE
• RoHS compliance: Yes

These parameters define the functional and mechanical compatibility required for direct substitution in RF coaxial applications.

Parameter Comparison

Engineering Selection Recommendations

The 3CV-P2(40) is the qualified substitute for BNC-P-3(40) in applications requiring 50-ohm BNC male plug connectors with solder termination. Both parts are RoHS compliant and manufactured by Hirose Electric Co Ltd, ensuring regulatory alignment and supply chain consistency.

The primary distinction is product lifecycle status: BNC-P-3(40) is obsolete, while 3CV-P2(40) carries Last Time Buy status with higher inventory availability (922 pcs vs. 707 pcs). For new designs or system refreshes, 3CV-P2(40) is the appropriate selection. For legacy system maintenance where BNC-P-3(40) stock exists, direct substitution with 3CV-P2(40) is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can 3CV-P2(40) directly replace BNC-P-3(40) in existing assemblies?

A: Yes. Both connectors share identical electrical specifications (50 ohms, 4 GHz maximum frequency), mechanical form factors (BNC plug, bayonet lock, free-hanging mount), and termination methods (solder). Direct substitution is valid for RF coaxial applications.

Q: What are the key differences between these parts?

A: The parts differ in product lifecycle status and operational temperature range. BNC-P-3(40) operates from -30°C to 60°C with 500 mating cycles, while 3CV-P2(40) operates from -25°C to 85°C with 10,000 mating cycles. For applications within the -30°C to 60°C window, both are functionally equivalent.

Q: Are there packaging differences?

A: BNC-P-3(40) packaging is unspecified in available data. 3CV-P2(40) is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Why is BNC-P-3(40) listed as obsolete?

A: Obsolescence reflects end-of-life status from the manufacturer. 3CV-P2(40) remains available as the current production equivalent, ensuring continued supply for new and replacement applications.

Q: Are both parts RoHS compliant?

A: Yes. Both BNC-P-3(40) and 3CV-P2(40) are RoHS compliant, meeting environmental and regulatory requirements for commercial and industrial RF applications.
