Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes

Amphenol RF 112123 is the primary direct equivalent to the 112119. Both parts share identical electrical and mechanical specifications, including 75 ohm impedance, crimp termination, 4 GHz frequency capability, and polyoxymethylene dielectric material. The 112123 carries an "Active" product status, ensuring ongoing availability and support. This part is the recommended first choice for direct replacement in new production and design updates.

Amphenol RF 112952 is a parametric equivalent offering identical core functionality with a dielectric material change from polyoxymethylene to polytetrafluoroethylene (PTFE). The 112952 maintains 4 GHz frequency capability and all other critical parameters. The PTFE dielectric provides enhanced environmental stability and lower moisture absorption compared to the acetal material. This part carries "Active" status and is suitable for applications requiring superior environmental performance.

Secondary Equivalent Substitutes

Cinch Connectivity Solutions Trompeter UPL220 Series (UPL220-009, UPL220-020, UPL220-025, UPL220-026) provides full parametric equivalence with 4 GHz frequency capability and PTFE dielectric material. These parts maintain all critical electrical specifications and carry "Active" product status. Cable group compatibility varies by part number, with UPL220-009 supporting Belden 8218 and Essex 21-597, UPL220-020 supporting Belden 9248, UPL220-025 supporting 734A, and UPL220-026 supporting 735A. Selection within this series depends on specific cable group requirements.

Limited Compatibility Substitutes

TE Connectivity AMP Connectors 1-1478103-0 and 6-1337511-0 and 6-1337517-0 provide functional equivalence with the following limitations:

• Frequency capability reduced to 2 GHz (versus 4 GHz for the main part)
• Contact termination differs: 1-1478103-0 uses solder termination; 6-1337511-0 and 6-1337517-0 support crimp or solder
• Body finish varies: 1-1478103-0 uses silver finish; others use nickel
• Center contact plating differs: 1-1478103-0 uses silver; others use gold
• Operating temperature range specified: -65°C to 165°C

These parts are suitable only for applications operating below 2 GHz and where the termination method and plating specifications are compatible with system requirements.

Compliance and Regulatory Status

All substitute parts maintain ROHS3 or RoHS compliance and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage environments. REACH compliance status is documented for all Amphenol RF and Cinch Trompeter parts. TE Connectivity parts show either RoHS Compliant or Vendor Undefined REACH status.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112123 be used as a direct replacement for the 112119?

A: Yes. The 112123 is a direct equivalent with identical electrical and mechanical specifications. Both parts feature 75 ohm impedance, crimp termination, 4 GHz frequency capability, and polyoxymethylene dielectric material. The 112123 carries "Active" product status, making it the recommended replacement for the obsolete 112119.

Q: What is the difference between the 112119 and the 112952?

A: The primary difference is the dielectric material. The 112119 uses polyoxymethylene (POM) acetal, while the 112952 uses polytetrafluoroethylene (PTFE). Both maintain 75 ohm impedance, crimp termination, and 4 GHz frequency capability. PTFE provides superior environmental stability and lower moisture absorption. The 112952 is suitable for applications requiring enhanced environmental performance.

Q: Are the Cinch Trompeter UPL220 series parts fully compatible with the 112119?

A: The UPL220 series parts (UPL220-009, UPL220-020, UPL220-025, UPL220-026) are parametrically equivalent with 75 ohm impedance, crimp termination, and 4 GHz frequency capability. Compatibility depends on cable group requirements. Each part number supports different cable groups: UPL220-009 for Belden 8218 and Essex 21-597, UPL220-020 for Belden 9248, UPL220-025 for 734A, and UPL220-026 for 735A. Select the part number matching your cable specification.

Q: Can TE Connectivity parts be used as substitutes for the 112119?

A: TE Connectivity parts 1-1478103-0, 6-1337511-0, and 6-1337517-0 provide functional equivalence with limitations. Maximum frequency is 2 GHz (versus 4 GHz for the 112119). The 1-1478103-0 uses solder termination and silver plating, while 6-1337511-0 and 6-1337517-0 support crimp or solder termination with gold plating. These parts are suitable only for applications operating below 2 GHz.

Q: What does "Not For New Designs" mean for the 112119?

A: This status indicates the part is obsolete or phased out by the manufacturer. New designs should not incorporate this part number. Existing designs using the 112119 should transition to an active equivalent such as the 112123 or 112952 to ensure long-term supply chain continuity and manufacturer support.

Q: How do I select between the Amphenol RF 112123 and 112952?

A: Both parts are direct equivalents. The 112123 uses polyoxymethylene dielectric, while the 112952 uses PTFE dielectric. For standard applications, the 112123 is appropriate. For applications requiring enhanced environmental stability, lower moisture absorption, or operation in humid or temperature-extreme environments, the 112952 is preferred.

Q: What is the significance of the dielectric material difference between parts?

A: Dielectric material affects signal integrity, environmental performance, and moisture absorption. Polyoxymethylene (POM) acetal is cost-effective and suitable for standard applications. Polytetrafluoroethylene (PTFE) provides superior environmental stability, lower moisture absorption, and better high-frequency performance. PTFE is preferred for demanding applications or environments with temperature or humidity extremes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry either ROHS3 Compliant or RoHS Compliant status, ensuring compliance with RoHS directives. Specific compliance levels vary by manufacturer and part number.

Q: What is the cable group compatibility requirement?

A: Cable group compatibility specifies which coaxial cable types are designed to work with each connector. The 112119 supports RG-59, 59B, 62, 140, 210, and Belden variants 8241, 8263, 8279, and 9209. Substitute parts support overlapping or identical cable groups. When selecting a substitute, verify that the cable group specification matches your application requirements.

Q: Can I use a part with lower frequency capability than the 112119?

A: Substitution with lower frequency capability is acceptable only if your application operates below the substitute part's maximum frequency. For example, TE Connectivity parts rated to 2 GHz are suitable for applications operating below 2 GHz but not for applications requiring 4 GHz capability. Verify your system's frequency requirements before selecting a substitute with reduced frequency rating.

Q: What is the difference between crimp and solder termination?

A: Crimp termination uses mechanical pressure to attach the connector to the cable, while solder termination uses molten solder to create the connection. The 112119 uses crimp termination. Most substitutes also use crimp termination. TE Connectivity part 1-1478103-0 uses solder termination exclusively, while 6-1337511-0 and 6-1337517-0 support both methods. Select based on your assembly process and equipment capabilities.
