Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6-1337494-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Mounting Feature: Bulkhead - Front Side Nut
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Number of Ports: 1
• Voltage Rating: 500 V
• Mating Cycles: 500

All identified substitute parts meet these mandatory parameters. Variations in dielectric material, center contact material, center contact plating, body material composition, and operating temperature ranges are secondary considerations that do not prevent functional substitution within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

TE Connectivity AMP Connectors Series (5227433-1, 5227661-1, 5227676-1, 5227677-1, 227676-2):

These parts are direct parametric equivalents manufactured by the original equipment supplier. Selection among these options is determined by compliance requirements and packaging needs:

• 5227661-1: Highest inventory availability (210,158 pcs). ROHS3 Compliant. Tube packaging. Tin center contact plating. Suitable for high-volume production requiring ROHS3 certification.

• 5227677-1: High inventory (2,402 pcs). ROHS3 Compliant. Bulk packaging. Gold center contact plating. Recommended for applications requiring gold plating and ROHS3 compliance.

• 5227676-1: Moderate inventory (1,291 pcs). RoHS Compliant. Bulk packaging. Gold center contact plating. Suitable for RoHS-compliant applications with gold plating preference.

• 5227433-1: Moderate inventory (885 pcs). RoHS Compliant. Bulk packaging. Tin center contact plating. Suitable for RoHS-compliant applications with tin plating.

• 227676-2: Lower inventory (737 pcs). RoHS non-compliant. Gold center contact plating. Not recommended for new designs requiring RoHS compliance.

Amphenol RF 031-6121:

This part is a cross-manufacturer equivalent with extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C). ROHS3 Compliant. Includes hardware (lockwasher, nut). Dielectric material is PTFE instead of PE or PMP. Insertion loss specified at 0.2dB. Suitable for applications requiring extended temperature performance or cross-manufacturer sourcing strategy.

Frequently Asked Questions (FAQ)

Q: Can 5227661-1 directly replace 6-1337494-2 in existing designs?

A: Yes. The 5227661-1 meets all mandatory electrical and mechanical parameters: BNC jack, female socket, 50 ohms, panel mount through-hole right-angle, bayonet lock, 4 GHz maximum frequency, 500 V rating, and 500 mating cycles. The dielectric material differs (PMP versus PE), but this does not affect functional compatibility within the specified electrical constraints.

Q: What is the difference between tin and gold center contact plating options?

A: Both tin-plated (5227433-1, 5227661-1) and gold-plated (5227676-1, 5227677-1, 031-6121) variants meet the 50-ohm impedance and electrical performance requirements. Selection depends on application-specific contact resistance, corrosion resistance, and cost considerations. The original 6-1337494-2 uses gold plating.

Q: Is the Amphenol RF 031-6121 electrically compatible?

A: Yes. The 031-6121 meets all mandatory parameters for BNC jack, female socket, 50-ohm impedance, panel mount through-hole right-angle configuration, bayonet lock fastening, 4 GHz frequency, 500 V rating, and 500 mating cycles. The extended operating temperature range (-65°C ~ 165°C) and PTFE dielectric material provide additional performance margin beyond the original part specification.

Q: Which substitute part has the best inventory availability?

A: The 5227661-1 has the highest inventory at 210,158 pieces, followed by 5227677-1 at 2,402 pieces. Both are active products with ROHS3 compliance.

Q: Are all substitute parts RoHS compliant?

A: Five of the six substitute parts are RoHS or ROHS3 compliant (5227433-1, 5227661-1, 5227676-1, 5227677-1, 031-6121). The 227676-2 is RoHS non-compliant and is not recommended for new designs subject to RoHS requirements.

Q: What packaging options are available?

A: Packaging varies by part number. The 5227661-1 is supplied in tube packaging. The 5227433-1, 5227676-1, 5227677-1, and 031-6121 are supplied in bulk packaging. The 227676-2 packaging is not specified.

Q: Does the Amphenol RF part include additional components?

A: Yes. The 031-6121 includes three pieces: one connector, one lockwasher, and one nut. Other TE Connectivity variants do not specify included hardware.
