TE Connectivity AMP Connectors 414338-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 414338-1 is an SMB Connector Plug with female socket configuration, rated for 50 Ohms impedance, designed for through-hole right-angle solder mounting on printed circuit boards. This coaxial RF connector operates at frequencies up to 4 GHz and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the 414338-1 is determined by strict adherence to the following critical parameters: SMB connector style, plug configuration with female socket, 50 Ohms impedance, through-hole right-angle mounting, solder termination for both contact and shield, snap-on fastening, and single-port design. The operating temperature range of -65°C to 165°C and mating cycle rating of 500 cycles establish the baseline mechanical and thermal requirements.

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent (5414338-1): Identical connector style, type, impedance, mounting configuration, and termination method. Differs in maximum frequency rating (3 GHz versus 4 GHz) and product compliance status.

Similar Manufacturer Alternative (72997): Maintains SMB style, 50 Ohms impedance, through-hole right-angle mounting, solder termination, and snap-on fastening. Differs in connector type (receptacle versus plug) and housing material composition.

Parametric Equivalent (2042-7511-000): Matches SMB style, plug configuration, female socket, 50 Ohms impedance, through-hole right-angle mounting, solder termination, snap-on fastening, and maximum frequency rating (4 GHz). Differs in center contact material and body material composition.

Engineering Selection Recommendations

5414338-1 (Direct Manufacturer Equivalent): This part is the direct equivalent from TE Connectivity AMP Connectors and maintains identical connector geometry, impedance, and termination specifications. The maximum frequency rating is reduced from 4 GHz to 3 GHz, which may limit applications requiring the full 4 GHz bandwidth. This part achieves RoHS compliance and REACH affected status, providing regulatory advantages over the obsolete 414338-1. Selection is appropriate for applications operating at or below 3 GHz where regulatory compliance is required.

2042-7511-000 (Parametric Equivalent): This Radiall USA part preserves the 4 GHz maximum frequency rating and maintains all critical electrical and mechanical parameters of the main part. It achieves ROHS3 compliance and REACH affected status. The center contact material differs (beryllium copper versus brass) and body material composition differs (brass versus zinc alloy), but these material changes do not alter the functional electrical characteristics. Selection is appropriate for applications requiring the full 4 GHz frequency range with modern regulatory compliance.

72997 (Similar Alternative): This Pomona Electronics part maintains SMB style, 50 Ohms impedance, through-hole right-angle mounting, and solder termination. However, it is configured as a receptacle rather than a plug, which represents a different connector gender and requires mating with a plug connector. The voltage rating is reduced to 250 V. This part is active and ROHS3 compliant. Selection requires verification that the receptacle configuration is compatible with the existing mating connector design.

Frequently Asked Questions (FAQ)

Q: Can 5414338-1 be used as a direct replacement for 414338-1 in all applications?

A: The 5414338-1 is functionally equivalent for applications operating at frequencies up to 3 GHz. Applications requiring operation at frequencies between 3 GHz and 4 GHz must use either the 2042-7511-000 or source the original 414338-1. All other electrical and mechanical parameters are identical.

Q: What is the primary difference between 2042-7511-000 and 414338-1?

A: The 2042-7511-000 maintains the 4 GHz maximum frequency rating and all critical electrical specifications. The primary differences are manufacturer (Radiall versus TE Connectivity), center contact material (beryllium copper versus brass), and body material (brass versus zinc alloy). These material differences do not affect electrical performance within the specified operating parameters.

Q: Why is 72997 listed as a substitute if it is a receptacle rather than a plug?

A: The 72997 is listed as a similar alternative because it shares the SMB style, 50 Ohms impedance, through-hole right-angle mounting, and solder termination. However, the receptacle configuration requires a mating plug connector, making it suitable only for applications where the circuit board design accommodates a receptacle-to-plug interface rather than a plug-to-plug interface.

Q: Are there compliance differences between the substitute parts?

A: Yes. The original 414338-1 is RoHS non-compliant. The 5414338-1 is RoHS compliant with REACH affected status. The 2042-7511-000 and 72997 are both ROHS3 compliant. For applications subject to RoHS or REACH regulations, the compliant alternatives are required.

Q: What is the voltage rating difference between 414338-1 and 72997?

A: The 414338-1 has a voltage rating of 335 V, while the 72997 has a voltage rating of 250 V. Applications requiring operation above 250 V must use either the 414338-1 or 5414338-1.

Q: Can insertion loss specifications be used to differentiate between substitute parts?

A: The 414338-1 and 5414338-1 both specify 0.6 dB insertion loss. The 72997 and 2042-7511-000 do not provide insertion loss specifications in their technical data. For applications where insertion loss is a critical parameter, the TE Connectivity parts with specified values are preferred.

Q: What packaging options are available for these substitute parts?

A: The 414338-1 is supplied in unspecified packaging. The 5414338-1, 72997, and 2042-7511-000 are all supplied in bulk packaging. Bulk packaging is standard for these coaxial connector types and does not affect functional compatibility.
