TE Connectivity AMP Connectors 414567-1 BNC Coaxial Adapter Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 414567-1 is a coaxial connector adapter designed for RF applications requiring 50-ohm impedance matching. This component functions as a jack-to-jack BNC adapter, enabling connection between two female BNC sockets in a straight, free-hanging configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and ensure long-term component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 414567-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Adapter Series: BNC to BNC
• Center Gender: Female to Female
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Bayonet Lock
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 221551-1 meets all mandatory matching parameters, establishing functional and mechanical equivalence. Differences in center contact plating (gold versus silver) and dielectric material specification do not affect substitution eligibility within the defined parameter set.

Engineering Selection Recommendations

For New Designs and Forward-Looking Applications:

Select TE Connectivity AMP Connectors 221551-1 as the primary component choice. This part is classified as active product status, ensuring sustained manufacturing support and long-term availability. The 221551-1 achieves ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic components in most jurisdictions. These compliance certifications position the 221551-1 for integration into systems subject to environmental and hazardous substance restrictions.

For Legacy System Maintenance and Field Replacement:

The 414567-1 remains available in inventory (1091 units) for applications where existing systems are locked to this specific part number or where regulatory exemptions apply to non-compliant components. However, new procurement should transition to 221551-1 to align with modern compliance frameworks.

Compliance Transition Consideration:

The shift from RoHS non-compliant (414567-1) to ROHS3 compliant (221551-1) represents a material change in regulatory posture. Organizations operating under RoHS directives must prioritize 221551-1 for all new installations and future-dated replacements.

Frequently Asked Questions (FAQ)

Q: Can 221551-1 directly replace 414567-1 in existing installations?

A: Yes. Both parts share identical adapter type, BNC series configuration, female-to-female center gender, 50-ohm impedance, straight style, free-hanging mounting, bayonet fastening, nickel body finish, and phosphor bronze center contact material. Mechanical and electrical compatibility is established across all critical parameters.

Q: What is the significance of the center contact plating difference (gold versus silver)?

A: Center contact plating is not included in the mandatory matching parameter set for this substitution analysis. Both gold and silver plating provide corrosion resistance and electrical conductivity suitable for RF coaxial applications. The plating difference does not affect substitution eligibility.

Q: Why is 414567-1 classified as obsolete?

A: Obsolete status indicates that TE Connectivity AMP Connectors has discontinued active manufacturing and support for this part number. While inventory remains available, no new production is scheduled. Organizations should transition to active alternatives such as 221551-1 to ensure supply chain continuity.

Q: Does the dielectric material difference (unspecified for 414567-1 versus PTFE for 221551-1) affect compatibility?

A: Dielectric material is not included in the mandatory matching parameter set. The specification of PTFE dielectric in 221551-1 represents an engineering enhancement that does not compromise substitution eligibility. PTFE is a standard dielectric material in RF coaxial connectors.

Q: What packaging options are available?

A: The 414567-1 packaging specification is not provided in the available data. The 221551-1 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications before finalizing orders.

Q: Are there any regulatory barriers to using 221551-1 in place of 414567-1?

A: No regulatory barriers exist for substitution. The 221551-1 achieves ROHS3 compliance and REACH affected status, meeting or exceeding the regulatory requirements applicable to the non-compliant 414567-1. Organizations subject to RoHS directives should prioritize 221551-1.

Q: What is the current inventory status for both parts?

A: The 414567-1 has 1091 units in stock (new original condition). The 221551-1 has 880 units in stock (new original condition). Both parts are available for immediate procurement.
