Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 227661-1 are classified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Core Electrical Parameters: Connector style (BNC), connector type (Jack, Female Socket), impedance (50 Ohms), frequency capability (up to 4 GHz), voltage rating (500 V), and mating cycles (500).

Core Mechanical Parameters: Mounting type (Panel Mount, Through Hole, Right Angle), mounting feature (Bulkhead - Front Side Nut), contact termination (Solder), shield termination (Solder), and fastening type (Bayonet Lock).

Material and Environmental Parameters: Operating temperature range (-55°C ~ 85°C), center contact material (Phosphor Bronze), body material composition, and housing color (Silver).

Parts are grouped into two categories:

Direct Manufacturer Equivalents: Parts from TE Connectivity AMP Connectors that differ only in packaging format (Tray vs. Tube) or minor material variations (center contact plating: Tin vs. Gold, body finish: Nickel vs. Tin, dielectric material composition).

Parametric Equivalents from Alternative Manufacturers: Parts from Amphenol RF, Samtec Inc., and Cinch Connectivity Solutions that maintain all critical electrical and mechanical parameters while potentially varying in frequency capability, dielectric material, operating temperature range, or included accessories.

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity AMP Connectors):

The TE Connectivity parts 5227661-1, 227676-1, 5413879-1, 5415025-1, and 5415025-2 are direct manufacturer equivalents with identical electrical and mechanical specifications. Selection among these parts is determined by packaging requirements and compliance status:

5227661-1 is functionally equivalent to 227661-1 with tube packaging instead of tray packaging. This part maintains ROHS3 compliance and REACH affected status with significantly higher inventory availability (210,158 pcs).

227676-1 differs only in center contact plating (Gold vs. Tin) and achieves REACH unaffected status, making it suitable for applications with REACH compliance requirements. This part is in active status with ROHS3 compliance.

5413879-1 provides gold-plated center contacts with ROHS3 compliance and REACH affected status. Inventory is substantial at 4,924 pcs.

5415025-1 and 5415025-2 feature tin body finish and mixed dielectric materials (PTFE and PMP for 5415025-1; PTFE only for 5415025-2). Both maintain 500 mating cycles and 500 V rating. 5415025-2 is marked as obsolete and should not be selected for new designs despite available inventory.

Alternative Manufacturer Substitutes:

031-5640 (Amphenol RF) maintains all core mechanical parameters and 50 ohm impedance with ROHS3 compliance. However, frequency capability is limited to 1 GHz compared to 4 GHz for the main part. This part includes board guide features and polypropylene dielectric material. Selection is appropriate only for applications operating below 1 GHz.

BNC5-J-P-GN-RA-BH2D (Samtec Inc.) provides 4 GHz frequency capability with extended operating temperature range (-65°C ~ 125°C) and ROHS3 compliance. This part includes lockwasher and nut accessories. REACH affected status applies. Voltage rating and mating cycles are not specified; confirmation is required for applications with specific electrical stress requirements.

VBM211 (Cinch Connectivity Solutions) maintains 4 GHz frequency capability and 500 V rating with RoHS compliance. Operating temperature range is limited to -40°C ~ 85°C. This part includes lockwasher and nut accessories. REACH status is not specified. Selection is appropriate for applications within the stated temperature range.

Compliance and Status Considerations:

All active status parts are suitable for new designs. Part 5415025-2 is obsolete and should not be selected for new applications.

ROHS3 compliant parts (227661-1, 5227661-1, 227676-1, 5413879-1, 031-5640, BNC5-J-P-GN-RA-BH2D) are preferred for applications subject to RoHS directive requirements.

REACH affected parts require additional documentation and supply chain verification for applications in REACH-regulated markets. Part 227676-1 is REACH unaffected and is the preferred choice when REACH compliance is a critical requirement.

Frequently Asked Questions (FAQ)

Q: Can 227661-1 be directly replaced with 5227661-1?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors with identical electrical and mechanical specifications. The only difference is packaging format: 227661-1 is supplied in trays while 5227661-1 is supplied in tubes. Functional performance is equivalent.

Q: What is the difference between tin-plated and gold-plated center contacts?

A: Center contact plating affects contact resistance and corrosion resistance. Tin plating (227661-1, 5227661-1) provides standard performance. Gold plating (227676-1, 5413879-1, 5415025-1, 5415025-2, 031-5640, BNC5-J-P-GN-RA-BH2D, VBM211) provides enhanced corrosion resistance and lower contact resistance. Selection depends on application environmental conditions and performance requirements.

Q: Why is the frequency specification different for 031-5640?

A: The Amphenol RF part 031-5640 is specified for 1 GHz maximum frequency, compared to 4 GHz for other parts. This reflects design differences in dielectric material (polypropylene vs. polymethylpentene or PTFE) and internal geometry. This part is suitable only for applications operating at frequencies up to 1 GHz.

Q: What does REACH affected status mean?

A: REACH affected status indicates the part contains substances of concern regulated under the REACH directive (Registration, Evaluation, Authorization and Restriction of Chemicals). Parts with REACH affected status require additional documentation and supply chain verification for use in European Union markets. Part 227676-1 is REACH unaffected and is the preferred choice when REACH compliance is required.

Q: Can BNC5-J-P-GN-RA-BH2D be used in applications requiring -55°C operation?

A: Yes. BNC5-J-P-GN-RA-BH2D is specified for -65°C ~ 125°C operating temperature range, which exceeds the -55°C ~ 85°C range of 227661-1. This part is suitable for extended temperature applications.

Q: What accessories are included with BNC5-J-P-GN-RA-BH2D and VBM211?

A: Both parts include 3 pcs: 1 connector, 1 lockwasher, and 1 nut. The main part 227661-1 does not specify included accessories. Verify accessory requirements for your application before selection.

Q: Is 5415025-2 suitable for new designs?

A: No. Part 5415025-2 is marked as obsolete product status. New designs should select from active status parts: 227661-1, 5227661-1, 227676-1, 5413879-1, 5415025-1, 031-5640, BNC5-J-P-GN-RA-BH2D, or VBM211.

Q: What is the difference between polymethylpentene (PMP) and polytetrafluoroethylene (PTFE) dielectric materials?

A: Both materials are suitable for RF applications at 50 ohms impedance. PMP (used in 227661-1, 5227661-1, 227676-1, 5413879-1, and 5415025-1) provides good electrical properties and cost efficiency. PTFE (used in 5415025-1, 5415025-2, and BNC5-J-P-GN-RA-BH2D) provides superior high-frequency performance and temperature stability. Selection depends on frequency requirements and operating environment.

Q: Can parts with different body materials (Zinc vs. Zinc Die Cast vs. Zinc Alloy) be interchanged?

A: Yes, for functional purposes. All body materials are suitable for the specified 50 ohm BNC connector application. Material differences reflect manufacturing processes and do not affect electrical performance or mechanical compatibility. Selection may be driven by availability and cost considerations.

Q: What is the significance of the 500 mating cycles specification?

A: The 500 mating cycles specification indicates the connector is rated for 500 connect/disconnect operations before performance degradation. This is a standard specification for BNC connectors in this class. Applications requiring higher cycle counts should confirm this specification with the manufacturer.
