Engineering Selection Recommendations

Primary Recommendation: 5227079-6

The 5227079-6 is the preferred parametric equivalent for the 225395-3. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical specifications including 50-ohm impedance, 4 GHz maximum frequency, 500-volt rating, and 0.2 dB insertion loss. The 5227079-6 is in active product status with significantly higher inventory availability (64,520 units). The only material variation is the dielectric material (Polyethylene versus PTFE), which does not affect functional compatibility for the specified cable groups. Both parts support RG-55, 55A, 55B, and 223 cable groups. The 5227079-6 carries RoHS Compliant certification.

Secondary Recommendation: 031-326

The Amphenol RF 031-326 is an active product suitable for applications requiring extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C). This part maintains all critical electrical parameters and supports crimp or solder termination options. The 031-326 is ROHS3 Compliant and REACH Affected. Cable group compatibility includes RG-55, 142, 223, and 400. This part is appropriate when thermal performance beyond the standard range is required.

Alternative for Legacy Systems: 000-36875

The Amphenol RF 000-36875 is marked "Not For New Designs" but remains available with 1,083 units in stock. This part is suitable only for maintenance, repair, or replacement of existing systems. The maximum frequency specification is 1 GHz, which is below the 4 GHz capability of the main part. This part supports both crimp and solder termination and is ROHS3 Compliant with REACH Affected status.

Not Recommended for New Designs: 5225395-3 and 112562

The 5225395-3 is marked Obsolete and should not be selected for new applications. The 112562 is marked "Not For New Designs" and supports a different cable group (RG-8 series) not compatible with the primary application cable groups. Both parts should be reserved for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can the 5227079-6 be used as a direct replacement for the 225395-3?

A: Yes. The 5227079-6 meets all mandatory electrical and mechanical parameters: 50-ohm impedance, BNC plug male pin configuration, crimp termination, 4 GHz frequency capability, 500-volt rating, and 500 mating cycles. Both parts support the same cable groups (RG-55, 55A, 55B, 223). The dielectric material difference (Polyethylene versus PTFE) does not affect functional compatibility for these cable types.

Q: What is the difference between the 031-326 and the 225395-3?

A: The 031-326 offers an extended operating temperature range (-65°C ~ 165°C compared to -55°C ~ 85°C) and is manufactured by Amphenol RF rather than TE Connectivity. Both parts maintain identical electrical specifications and support crimp termination. The 031-326 additionally supports solder termination. The 031-326 is ROHS3 Compliant and REACH Affected, while the 225395-3 status is "Not applicable" for RoHS.

Q: Why is the 000-36875 marked "Not For New Designs"?

A: The 000-36875 has a maximum frequency specification of 1 GHz, which is below the 4 GHz capability of the 225395-3. This frequency limitation restricts its use to legacy applications operating below 1 GHz. New designs should utilize parts with 4 GHz capability such as the 5227079-6 or 031-326.

Q: Can the 112562 be used in place of the 225395-3?

A: No. Although the 112562 maintains the same electrical specifications and 4 GHz frequency capability, it is designed for a different cable group (RG-8 series) and is marked "Not For New Designs." The 112562 is suitable only for maintenance of existing systems that originally specified this part.

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

A: The 225395-3 and 5227079-6 are supplied without specified packaging designation. The 000-36875 is supplied in Bulk packaging. The 031-326 is supplied in Bulk packaging. The 112562 is supplied in Bag packaging. Packaging selection should be coordinated with procurement requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: The 225395-3 has "Not applicable" RoHS status. The 5227079-6 is RoHS Compliant. The 5225395-3 is RoHS Compliant. The 000-36875 and 031-326 are both ROHS3 Compliant. The 112562 is ROHS3 Compliant. For applications requiring RoHS compliance, the 5227079-6, 031-326, or 112562 are appropriate selections.

Q: What is the inventory status for each part?

A: The 5227079-6 has the highest availability with 64,520 units in stock. The 000-36875 has 1,083 units. The 031-326 has 948 units. The 225395-3 has 905 units. The 5225395-3 has 879 units. The 112562 has 751 units. For applications requiring immediate availability, the 5227079-6 is the optimal choice.

Q: Can the 031-326 be used in high-temperature applications?

A: Yes. The 031-326 is rated for operating temperatures from -65°C to 165°C, which exceeds the -55°C to 85°C range of the 225395-3. Applications requiring operation above 85°C should specify the 031-326 or equivalent parts with extended temperature ratings.
