Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 112576 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Impedance: 75 Ohms (all substitutes match)
• Frequency - Max: 4 GHz (all substitutes match)
• Voltage Rating: 500 V (all substitutes match)

Mechanical Parameters:

• Connector Style: BNC (all substitutes match)
• Connector Type: Plug, Male Pin (all substitutes match)
• Contact Termination: Crimp (all substitutes match)
• Shield Termination: Crimp (all substitutes match)
• Mounting Type: Free Hanging (In-Line) (all substitutes match)
• Fastening Type: Bayonet Lock (all substitutes match)

Material & Environmental Parameters:

• Body Material: Brass (all substitutes match)
• Body Finish: Nickel (all substitutes match)
• Center Contact Material: Brass (all substitutes match)
• Center Contact Plating: Gold (all substitutes match)
• Dielectric Material: PTFE (all substitutes match)
• Operating Temperature: -65°C ~ 165°C (all substitutes match)
• RoHS Status: ROHS3 Compliant (all substitutes match)
• MSL: 1 (Unlimited) (all substitutes match)

Substitutes are differentiated by manufacturer, product status, packaging format, cable group compatibility, and included components. The Amphenol RF 112606 is a direct manufacturer equivalent with active product status. Cinch Connectivity Solutions Trompeter UPL220 series parts (UPL220-009, UPL220-020, UPL220-025, UPL220-026) are cross-manufacturer equivalents with active status and bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status: The Amphenol RF 112576 carries a "Not For New Designs" designation. For new design implementations, the Amphenol RF 112606 is the direct manufacturer equivalent with active product status. Both parts maintain identical electrical and mechanical specifications, with the 112606 including an additional ferrule component in its package.

For Cross-Manufacturer Equivalence: The Cinch Connectivity Solutions Trompeter UPL220 series (UPL220-009, UPL220-020, UPL220-025, UPL220-026) provides active cross-manufacturer alternatives. All four variants meet the complete electrical and mechanical parameter requirements of the 112576. Selection among these variants depends on cable group compatibility requirements:

• UPL220-009: Compatible with Belden 8218, YR23023, Essex 21-597
• UPL220-020: Compatible with Belden 9248
• UPL220-025: Compatible with 734A
• UPL220-026: Compatible with 735A

For Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. The Amphenol RF 112606 and Cinch UPL220-009, UPL220-025, and UPL220-026 carry explicit ROHS3 Compliant designation. The Cinch UPL220-020 carries RoHS Compliant designation without specific ROHS3 notation. All parts are REACH Affected and carry EAR99 ECCN classification.

For Packaging Considerations: The Amphenol RF 112576 and 112606 are supplied in bag packaging. The Cinch UPL220 series is supplied in bulk packaging, which may affect procurement and inventory management workflows.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112606 be used as a direct replacement for the 112576?

A: Yes. The 112606 is electrically and mechanically equivalent to the 112576 across all critical parameters: 75-ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, BNC plug male pin configuration, crimp termination, bayonet lock fastening, and identical material specifications. The primary difference is product status (Active vs. Not For New Designs) and packaging inclusion (112606 includes an additional ferrule). Both support the same cable groups.

Q: What determines compatibility between the 112576 and Cinch UPL220 series connectors?

A: Compatibility is determined by electrical and mechanical parameter equivalence. All UPL220 variants match the 112576 across impedance (75 Ohms), frequency rating (4 GHz), voltage rating (500 V), connector style (BNC plug male pin), termination method (crimp), mounting type (free hanging in-line), fastening mechanism (bayonet lock), and material composition (brass body with nickel finish, gold-plated brass center contact, PTFE dielectric). Cable group compatibility varies by variant and should be verified against application requirements.

Q: Why do the Cinch UPL220 variants have different cable group specifications?

A: Cable group specifications reflect the physical dimensions and contact sizing optimized for specific coaxial cable types. While all UPL220 variants are electrically and mechanically equivalent to the 112576, each variant is engineered for optimal performance with particular cable groups. Selection should be based on the cable type used in the application.

Q: Does the additional ferrule included with the Amphenol RF 112606 affect compatibility?

A: No. The ferrule is a component included in the package and does not affect electrical or mechanical compatibility. The 112606 remains functionally equivalent to the 112576 for all connector applications.

Q: Are there compliance differences between the substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. The Cinch UPL220-020 carries RoHS Compliant designation without explicit ROHS3 notation, while the 112606, UPL220-009, UPL220-025, and UPL220-026 carry explicit ROHS3 Compliant designation. All parts are REACH Affected and EAR99 classified.

Q: What is the difference between bag and bulk packaging?

A: Bag packaging (112576, 112606) typically includes individual connector units with associated components in sealed bags, suitable for smaller quantity orders and component traceability. Bulk packaging (UPL220 series) supplies connectors in larger quantities without individual bagging, typically used for high-volume manufacturing operations. Packaging format does not affect electrical or mechanical performance.

Q: Can I use a UPL220 variant if my cable group is not listed in its specifications?

A: Cable group specifications indicate the connector's optimized dimensional and contact characteristics for those specific cable types. Using a variant outside its specified cable group may result in improper contact engagement or mechanical fit. Selection should be based on cable group compatibility.
