PA901074 BNC to F Coaxial Adapter Connector

Part Overview

The PA901074 is a coaxial adapter connector manufactured by Greenlee Communications, designed to convert between BNC plug (male pin) and F jack (female socket) configurations. This adapter operates at 75 ohms impedance and is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying active equivalent parts is essential for ongoing system maintenance and new design implementations. The substitute part maintains functional and electrical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PA901074 with part number 6779 (Pomona Electronics) is based on strict electrical and mechanical parameter alignment:

Critical Matching Parameters:

• Adapter series: BNC to F (identical conversion path)
• Impedance: 75 ohms (electrical compatibility maintained)
• Adapter type: Plug to Jack (same mating configuration)
• Center gender: Female to Male (identical pin/socket orientation)
• Convert From: BNC Plug, Male Pin (same source connector)
• Convert To: F Jack, Female Socket (same target connector)
• Body material: Brass with nickel finish (mechanical compatibility)

The substitute part 6779 maintains all critical electrical and mechanical parameters required for direct functional replacement. The primary distinction is product status: 6779 is active and available, whereas PA901074 is obsolete.

Engineering Selection Recommendations

For New Designs and Ongoing Applications:

Part number 6779 (Pomona Electronics) is the appropriate selection for applications requiring a BNC to F coaxial adapter connector. This part maintains full electrical and mechanical compatibility with the obsolete PA901074 while offering the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance supports regulatory requirements for new equipment designs
• Higher inventory levels (1550 units) provide immediate availability
• Specified operating temperature range (-40°C to 65°C) and mating cycle rating (500 cycles) provide defined performance parameters
• Gold-plated center contact and PTFE dielectric material support signal integrity in RF applications

For Legacy System Maintenance:

Existing installations using PA901074 may continue operation with current stock. When replacement becomes necessary, 6779 provides direct functional substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can part 6779 directly replace PA901074 in existing applications?

A: Yes. Both parts share identical electrical specifications (75 ohm impedance, BNC to F conversion) and mechanical configuration (brass body with nickel finish, plug-to-jack adapter type). No circuit modification or mechanical rework is required.

Q: What is the primary reason for substitution?

A: PA901074 is classified as obsolete. Part 6779 is an active product with confirmed availability and supply continuity, making it the appropriate choice for new designs and long-term system support.

Q: Are there compliance differences between the two parts?

A: Yes. Part 6779 is ROHS3 compliant, while PA901074 lists RoHS status as not applicable. For applications subject to RoHS regulations, 6779 is the required selection.

Q: What packaging is available for part 6779?

A: Part 6779 is supplied in bulk packaging, suitable for production assembly and field service applications.

Q: Are the RF performance characteristics equivalent?

A: Both parts operate at 75 ohms impedance. Part 6779 specifies a maximum frequency of 1.5 GHz and insertion loss characteristics. PA901074 does not provide frequency or insertion loss specifications in available documentation.

Q: What is the mating cycle rating for part 6779?

A: Part 6779 is rated for 500 mating cycles, providing a defined service life for connector engagement and disengagement operations.

Q: Are there material differences in the center contact?

A: Yes. Part 6779 specifies beryllium copper and brass center contact material with gold plating. PA901074 center contact material is not specified in available documentation.
