Engineering Selection Recommendations

Primary Recommendation: Amphenol RF 112589

Part 112589 is the direct successor to 112562. Both parts are manufactured by Amphenol RF with identical electrical specifications (50 Ohms, 4 GHz, 500 V, 0.2 dB insertion loss), identical mechanical configuration (BNC plug, crimp termination, bayonet lock), and identical cable group compatibility (RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393). The primary distinction is product status: 112589 is Active, whereas 112562 is Not For New Designs. Both are ROHS3 Compliant and REACH Affected. This part is suitable for direct replacement in all applications.

Secondary Recommendation: Amphenol RF 112627

Part 112627 meets all electrical and mechanical requirements identical to 112562 and 112589. It is Active status and ROHS3 Compliant. Cable group compatibility is identical. This part serves as an alternative source from the same manufacturer.

Alternative Recommendation: Amphenol RF 031-5999-RFX

Part 031-5999-RFX is a parametric equivalent with identical electrical performance and cable group compatibility. The dielectric material differs (POM Acetal instead of PTFE) and operating temperature range is specified (-65°C ~ 165°C). This part is Active status and ROHS3 Compliant. Selection of this part is appropriate when extended operating temperature range is required. Packaging is Bulk rather than Bag.

Not Recommended: TE Connectivity and Pomona Electronics Parts

Parts 1-5221128-1, 2-331350-1, 225395-3, 5227079-6, and 73043 are classified as Similar Parts due to cable group incompatibility or reduced frequency performance. Part 1-5221128-1 is Obsolete. Part 2-331350-1 is Discontinued at DiGi Electronics. Part 73043 has maximum frequency of 2 GHz, below the 4 GHz specification of 112562. Parts 225395-3 and 5227079-6 are compatible with RG-55 cable groups, not the RG-8 series specified for 112562. These parts should not be selected as direct replacements without cable group verification and application-specific testing.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112589 be used as a direct replacement for 112562?

A: Yes. Both parts are identical in electrical specifications (50 Ohms, 4 GHz, 500 V, 0.2 dB insertion loss), mechanical configuration (BNC plug, crimp termination, bayonet lock), and cable group compatibility (RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393). The only difference is product status: 112589 is Active while 112562 is Not For New Designs. Direct substitution is appropriate.

Q: What is the difference between 112562 and 031-5999-RFX?

A: Both parts meet identical electrical and mechanical requirements and support the same cable groups. The differences are: (1) Dielectric material: 112562 uses PTFE, while 031-5999-RFX uses POM Acetal; (2) Operating temperature: 031-5999-RFX specifies -65°C ~ 165°C, while 112562 does not specify operating temperature; (3) Packaging: 112562 is supplied in Bag, while 031-5999-RFX is supplied in Bulk. Selection depends on temperature requirements and packaging preferences.

Q: Why are TE Connectivity parts listed as Similar rather than Direct Equivalents?

A: TE Connectivity parts differ in cable group compatibility. Part 1-5221128-1 is compatible with RG-59 series cables, not RG-8 series. Parts 225395-3 and 5227079-6 are compatible with RG-55 series cables. Part 2-331350-1 is compatible with RG-58 series cables. These cable group differences affect physical fit and performance characteristics. Additionally, 1-5221128-1 is Obsolete and 2-331350-1 is Discontinued at DiGi Electronics.

Q: Can Pomona Electronics 73043 replace Amphenol RF 112562?

A: No. While both are 50-ohm BNC plugs with crimp termination, part 73043 has a maximum frequency of 2 GHz, compared to 4 GHz for 112562. Additionally, 73043 is compatible with RG-8, 9, 11, 213, 214 cable groups, while 112562 supports RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393. The frequency limitation makes 73043 unsuitable for applications requiring 4 GHz performance.

Q: What does "Not For New Designs" mean for part 112562?

A: "Not For New Designs" indicates that Amphenol RF has superseded this part with newer alternatives. While 112562 remains available in inventory (751 pcs), it is not recommended for new product development. Amphenol RF 112589 or 112627 are the recommended alternatives for new designs.

Q: Are all substitute parts ROHS3 Compliant?

A: Amphenol RF parts 112562, 112589, 031-5999-RFX, and 112627 are all ROHS3 Compliant. TE Connectivity part 1-5221128-1 is RoHS Compliant (not specified as ROHS3). TE Connectivity part 2-331350-1 is ROHS3 Compliant. TE Connectivity parts 225395-3 and 5227079-6 have RoHS status listed as "Not applicable" or "RoHS Compliant" respectively. Pomona Electronics 73043 is ROHS3 Compliant. Verify compliance requirements for your specific application.

Q: What is the difference between Bag and Bulk packaging?

A: Bag packaging (used for 112562, 112589, 112627) typically contains a smaller quantity of units in protective packaging suitable for component-level distribution. Bulk packaging (used for 031-5999-RFX, 73043) typically contains larger quantities with minimal packaging, suitable for high-volume manufacturing operations. Selection depends on procurement volume and inventory management requirements.

Q: Can I use part 5227079-6 instead of 112562?

A: Part 5227079-6 meets the electrical specifications (50 Ohms, 4 GHz, 500 V, 0.2 dB insertion loss) but is designed for RG-55 cable groups, not RG-8 series. Cable group incompatibility means the connector may not fit properly or perform as specified with RG-8 cables. This part is not suitable as a direct replacement without cable group verification.

Q: What is the significance of the dielectric material difference between PTFE and POM Acetal?

A: Both PTFE and POM Acetal are suitable dielectric materials for 50-ohm BNC connectors. PTFE (Polytetrafluoroethylene) offers superior high-frequency performance and temperature stability. POM Acetal (Polyoxymethylene) provides mechanical strength and dimensional stability. The choice between them depends on application requirements. Part 031-5999-RFX with POM Acetal specifies an extended operating temperature range (-65°C ~ 165°C), making it suitable for extreme temperature environments.
