Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 031-10-1002 is determined by the following critical parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder Cup
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Rear Side Nut
• Fastening Type: Bayonet Lock
• Number of Ports: 1

All four identified substitute parts (Pomona Electronics 3778, TE Connectivity 5227726-1, 5227726-2, and 5227726-3) meet these mandatory parameters. Variations in secondary parameters such as center contact material, body material composition, dielectric material, and plating specifications do not preclude substitution when the core electrical and mechanical interfaces remain identical.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 031-10-1002 Primary Selection: The Amphenol RF 031-10-1002 is ROHS3 compliant and REACH affected, meeting current regulatory requirements for restricted substance control. This part carries an active product status with established production support.

TE Connectivity 5227726-2 Preferred Substitute: The TE Connectivity 5227726-2 matches the primary part's ROHS3 compliance status and REACH affected designation. This part provides the closest regulatory alignment and is available in tray packaging with 1,927 units in stock. Operating temperature range of -65°C to 165°C and 500 V voltage rating are specified.

TE Connectivity 5227726-1 Alternative Substitute: The TE Connectivity 5227726-1 is RoHS compliant with REACH affected status. This variant provides identical mechanical and electrical interfaces with specified operating temperature and voltage ratings. Tin plating on the center contact differs from the primary part's gold plating.

TE Connectivity 5227726-3 Alternative Substitute: The TE Connectivity 5227726-3 features gold center contact plating matching the primary part. However, this variant is RoHS non-compliant, limiting its use in applications requiring RoHS certification. REACH affected status is confirmed.

Pomona Electronics 3778 Alternative Substitute: The Pomona Electronics 3778 provides equivalent mechanical and electrical performance with gold center contact plating. RoHS status is not applicable, and REACH unaffected designation indicates this part may not be subject to REACH regulations. Bulk packaging is provided with 2,133 units in stock. Dielectric material is PTFE rather than PPO or PBT.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 3778 be used as a direct replacement for the Amphenol RF 031-10-1002?

A: The Pomona Electronics 3778 meets all mandatory electrical and mechanical parameters: BNC connector style, female socket jack configuration, 50 ohm impedance, solder cup termination, panel mount bulkhead configuration, and bayonet lock fastening. The connector interfaces are functionally equivalent. Differences in dielectric material (PTFE versus PPO), center contact material (beryllium copper versus phosphor bronze), and regulatory status do not affect mechanical or electrical compatibility at the interface level.

Q: What is the difference between the three TE Connectivity variants (5227726-1, 5227726-2, 5227726-3)?

A: All three TE Connectivity variants share identical mechanical and electrical specifications. The primary differences are in center contact plating: 5227726-1 uses tin plating, 5227726-2 uses silver plating, and 5227726-3 uses gold plating. Additionally, 5227726-2 is ROHS3 compliant matching the primary part, while 5227726-1 is RoHS compliant and 5227726-3 is RoHS non-compliant.

Q: Does the difference in body material (brass versus zinc) affect substitution compatibility?

A: The Amphenol RF 031-10-1002 uses brass body material, while TE Connectivity variants use zinc body material. Both materials are finished with nickel plating. Body material composition does not affect the connector's electrical performance or mechanical interface compatibility at the mating surface.

Q: Are the TE Connectivity parts suitable for applications requiring ROHS3 compliance?

A: The TE Connectivity 5227726-2 is ROHS3 compliant and is suitable for applications requiring ROHS3 certification. The TE Connectivity 5227726-1 is RoHS compliant but not specifically ROHS3 certified. The TE Connectivity 5227726-3 is RoHS non-compliant and is not suitable for applications requiring RoHS certification.

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

A: The Amphenol RF 031-10-1002 packaging is not specified in the provided data. The Pomona Electronics 3778 is supplied in bulk packaging. All three TE Connectivity variants (5227726-1, 5227726-2, 5227726-3) are supplied in tray packaging.

Q: Can I use a substitute part with different center contact plating in a high-frequency RF application?

A: All identified substitute parts maintain the same 50 ohm impedance and connector geometry. Center contact plating variations (gold, silver, or tin) do not alter the fundamental RF performance characteristics or impedance matching at the interface. Selection should be based on application-specific requirements for contact resistance, corrosion resistance, and regulatory compliance rather than RF performance differences.

Q: What is the significance of the REACH affected versus REACH unaffected designation?

A: REACH affected status indicates the part is subject to European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. The Amphenol RF 031-10-1002 and most TE Connectivity variants are REACH affected. The Pomona Electronics 3778 is REACH unaffected, indicating it may not be subject to these regulations. Selection should align with supply chain regulatory requirements.
