TE Connectivity 414363-5 SMB Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 414363-5 is an SMB connector plug configured as a female socket with 50-ohm impedance, designed for right-angle solder termination on RF coaxial cables. This connector operates across the RG-174, RG-188, and RG-316 cable groups with a maximum frequency rating of 3 GHz and supports mating cycles up to 500. The part is currently active in production with 1090 pieces in stock inventory.

Substitute parts are necessary when addressing supply chain constraints, compliance requirements, or when alternative manufacturers offer equivalent electrical and mechanical performance within the same application parameters.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 414363-5 are classified into two categories based on electrical and mechanical equivalence:

Direct Manufacturer Substitutes (TE Connectivity): Parts 5414363-5, 414363-3, and 5414363-3 are manufactured by TE Connectivity and maintain identical electrical specifications including 50-ohm impedance, 3 GHz maximum frequency, 335 V voltage rating, 500 mating cycles, and 0.6 dB insertion loss. These parts share the same SMB connector style, female socket configuration, right-angle solder termination, and snap-on fastening. All support the same cable groups (RG-174, RG-188, RG-316) and operate across the -65°C to 165°C temperature range. Differences exist in RoHS compliance status and REACH regulatory classification.

Cross-Manufacturer Substitute (Amphenol RF): Part 903-367P-51A2 from Amphenol RF provides electrical and mechanical equivalence with the following distinctions: it supports a maximum frequency of 4 GHz (exceeding the 3 GHz requirement), is limited to RG-316 cable group compatibility, and uses zinc alloy body material instead of zinc. All other critical parameters—50-ohm impedance, 335 V voltage rating, 500 mating cycles, 0.6 dB insertion loss, solder contact termination, crimp shield termination, right-angle mounting, and snap-on fastening—remain equivalent.

Substitution eligibility is determined by matching the following key parameters: connector style (SMB), connector type (plug, female socket), impedance (50 ohms), contact and shield termination methods, mounting configuration, operating temperature range, voltage rating, mating cycle rating, and insertion loss specification.

Engineering Selection Recommendations

TE Connectivity 414363-5 (Original Part): This part is suitable for applications where RoHS non-compliance is acceptable and REACH regulatory status is not a constraint. It provides full compatibility with RG-174, RG-188, and RG-316 cable groups and maintains all specified electrical performance parameters.

TE Connectivity 5414363-5 (Direct Substitute): This part is the preferred substitute when RoHS compliance is required. It maintains identical electrical and mechanical specifications to the 414363-5 while achieving RoHS compliance and REACH affected status. Inventory availability is highest at 3229 pieces.

TE Connectivity 414363-3 (Parametric Equivalent): This part provides electrical and mechanical equivalence to the 414363-5 with identical RoHS non-compliant status. Selection between 414363-5 and 414363-3 is determined by application-specific requirements not specified in the provided parameters.

TE Connectivity 5414363-3 (Parametric Equivalent): This part achieves ROHS3 compliance and REACH affected status while maintaining full electrical and mechanical equivalence. It is suitable for applications requiring the highest regulatory compliance level.

Amphenol RF 903-367P-51A2 (Cross-Manufacturer Substitute): This part is suitable when cross-manufacturer sourcing is acceptable and applications operate exclusively with RG-316 cable. The 4 GHz maximum frequency rating exceeds the 3 GHz requirement of the original part. ROHS3 compliance and REACH affected status are achieved. Selection of this part requires confirmation that RG-174 and RG-188 cable compatibility is not required.

Frequently Asked Questions (FAQ)

Q: Can 5414363-5 be used as a direct replacement for 414363-5?

A: Yes. The 5414363-5 maintains identical electrical specifications (50-ohm impedance, 3 GHz maximum frequency, 335 V voltage rating, 500 mating cycles, 0.6 dB insertion loss), mechanical configuration (SMB plug, female socket, right-angle solder termination, snap-on fastening), and cable group compatibility (RG-174, RG-188, RG-316). The primary difference is RoHS compliance status, where 5414363-5 is RoHS compliant and 414363-5 is not.

Q: What is the difference between 414363-3 and 414363-5?

A: Both parts are manufactured by TE Connectivity and share identical electrical and mechanical specifications. The difference between these part numbers is not specified in the provided parameters. Selection between them is determined by application-specific requirements.

Q: Can the Amphenol RF 903-367P-51A2 be used in all applications where 414363-5 is specified?

A: The 903-367P-51A2 is electrically and mechanically equivalent for applications using RG-316 cable only. If the application requires RG-174 or RG-188 cable compatibility, the 903-367P-51A2 is not suitable. The 903-367P-51A2 supports 4 GHz maximum frequency, which exceeds the 3 GHz specification of the 414363-5.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS compliance is a regulatory requirement in certain markets and applications. The 414363-5 and 414363-3 are RoHS non-compliant, while 5414363-5, 5414363-3, and 903-367P-51A2 are RoHS3 compliant. Selection depends on whether the application or market requires RoHS compliance.

Q: Are all substitute parts packaged identically?

A: All parts listed are supplied in bulk packaging and include 3 pieces per connector unit (1 connector, 1 end cap, 1 ferrule). Packaging configuration is identical across all substitutes.

Q: What does REACH affected status indicate?

A: REACH affected status indicates that the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. Parts with REACH affected status have been evaluated for compliance with REACH regulations. The 414363-5 and 414363-3 have vendor undefined REACH status, while 5414363-5, 5414363-3, and 903-367P-51A2 have REACH affected status.

Q: Can 903-367P-51A2 be used if the application specifies RG-174 or RG-188 cables?

A: No. The 903-367P-51A2 is rated for RG-316 cable group only. If the application requires RG-174 or RG-188 cable compatibility, use 414363-5, 5414363-5, 414363-3, or 5414363-3.

Q: Which substitute part has the highest inventory availability?

A: The 5414363-5 has the highest inventory availability at 3229 pieces in stock.
