Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the Amphenol RF 282116-75 is based on the following critical parameters that must align for functional equivalence:

Mechanical Compatibility Parameters:

• Connector Style: 1.0/2.3 (physical form factor)
• Connector Type: Plug, Male Pin (mating interface)
• Mounting Type: Through Hole, Right Angle (PCB integration)
• Contact Termination: Solder (assembly method)
• Shield Termination: Solder (assembly method)

Electrical Performance Parameters:

• Impedance: 75 Ohms (signal integrity requirement)
• Frequency - Max: 4 GHz (bandwidth capability)
• Voltage Rating: 250 V (electrical stress rating)
• Mating Cycles: 500 (mechanical durability)

Material and Environmental Parameters:

• Body Material: Brass (structural integrity)
• Dielectric Material: PTFE (electrical properties)
• Operating Temperature Range: -65°C ~ 165°C (thermal envelope)
• RoHS3 Compliance (regulatory requirement)
• REACH Compliance (regulatory requirement)

Substitute parts must maintain all mechanical and electrical parameters within the specified ranges. Impedance matching is critical for RF applications and cannot be compromised.

Parameter Comparison

Engineering Selection Recommendations

The Rosenberger 45S201-400L5 presents a critical impedance mismatch with the Amphenol RF 282116-75. The Rosenberger part specifies 50 Ohm impedance while the primary part requires 75 Ohm impedance. This impedance difference directly affects signal integrity, reflection coefficients, and circuit performance in RF applications. The parts are not functionally equivalent for circuits designed around 75 Ohm impedance specifications.

Additionally, the Rosenberger 45S201-400L5 operates within a narrower temperature range (-55°C ~ 125°C) compared to the Amphenol RF 282116-75 (-65°C ~ 165°C). Applications requiring the full temperature envelope of the primary part cannot use the Rosenberger substitute without thermal performance degradation.

Both parts maintain Active product status, RoHS3 compliance, REACH compliance, and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010). Mechanical compatibility is confirmed through matching connector style, type, mounting configuration, and termination methods.

Selection of the Rosenberger part is restricted to applications where 50 Ohm impedance is the circuit requirement and operating temperatures remain within -55°C to 125°C boundaries.

Frequently Asked Questions (FAQ)

Q: Can the Rosenberger 45S201-400L5 be used as a direct replacement for the Amphenol RF 282116-75?

A: No. The Rosenberger part operates at 50 Ohm impedance while the Amphenol part is specified for 75 Ohm impedance. Impedance mismatch in RF circuits causes signal reflections and performance degradation. These parts are not interchangeable for 75 Ohm circuit designs.

Q: What is the significance of the impedance difference between these connectors?

A: Impedance is a critical RF parameter that determines how signals propagate through the connector and transmission line. A 75 Ohm connector in a 50 Ohm system (or vice versa) creates impedance discontinuities that result in signal reflections, increased insertion loss, and reduced circuit efficiency. The impedance must match the circuit design specification.

Q: Are both parts mechanically compatible with the same PCB footprint?

A: Yes. Both the Amphenol RF 282116-75 and Rosenberger 45S201-400L5 share identical mechanical specifications: 1.0/2.3 connector style, plug male pin configuration, through-hole right-angle mounting, and solder termination. PCB footprints are compatible.

Q: What is the operating temperature limitation of the Rosenberger part?

A: The Rosenberger 45S201-400L5 operates from -55°C to 125°C. The Amphenol RF 282116-75 operates from -65°C to 165°C. Applications requiring operation below -55°C or above 125°C must use the Amphenol part.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH affected, classified as EAR99 for export control, and share the same HTSUS code (8536.69.4010). Regulatory compliance is equivalent.

Q: What is the maximum frequency rating for these connectors?

A: Both the Amphenol RF 282116-75 and Rosenberger 45S201-400L5 are rated for maximum frequency operation to 4 GHz. Frequency capability is identical.

Q: Are there any differences in material composition between these parts?

A: Both parts use brass body material with gold finish, gold-plated center contacts, and PTFE dielectric material. Material composition is equivalent.

Q: What is the mating cycle rating for these connectors?

A: Both parts are rated for 500 mating cycles. Mechanical durability specifications are identical.

Q: Can these connectors be used in high-voltage applications?

A: Both parts carry a 250 V voltage rating. Voltage handling capability is equivalent.

Q: What packaging format is available for these parts?

A: Both the Amphenol RF 282116-75 and Rosenberger 45S201-400L5 are supplied in bulk packaging.
