Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP 1051109-1 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Connector style must be SMA
• Connector type must be Plug, Male Pin
• Impedance must be 50 Ohms
• Mounting type must be Free Hanging (In-Line), Right Angle
• Contact and shield termination must both be Solder
• Maximum frequency must be 18 GHz or greater
• Operating temperature range must encompass -65°C ~ 165°C
• Mating cycles must be 500 or greater
• Fastening type must be Threaded
• Number of ports must be 1

Secondary Considerations:

• Cable group compatibility (RG-402 or RG-405 semi-rigid)
• Body material and finish specifications
• Center contact material composition
• Voltage rating (minimum 335 V)
• Moisture sensitivity level (MSL 1)
• Regulatory compliance status

The two substitute parts listed below meet all primary substitution criteria and are therefore electrically and mechanically compatible with the main part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally equivalent to the TE Connectivity AMP 1051109-1 based on electrical and mechanical parameters. Selection between alternatives should be based on the following factors:

Molex 0732510552:

• Active product status ensures ongoing availability and manufacturer support
• Voltage rating of 500 V exceeds the original specification, providing additional margin
• Compatible with RG-402 semi-rigid cable, matching the original part specification
• Beryllium copper center contact material matches the original design
• REACH status listed as Vendor Undefined; clarification recommended for regulated applications

Cinch Connectivity Solutions 142-0693-101:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance provides enhanced regulatory alignment for new designs
• REACH Affected status matches the original part classification
• Compatible with RG-405 semi-rigid cable (.086" diameter), which differs from the original RG-402 specification
• Brass center contact material differs from the original beryllium copper composition
• Voltage rating of 335 V matches the original specification exactly

For applications requiring exact material composition and cable compatibility with RG-402 semi-rigid cable, the Molex 0732510552 provides the closest technical alignment. For applications prioritizing regulatory compliance and ROHS3 certification, the Cinch Connectivity Solutions 142-0693-101 is suitable, with consideration for the cable group difference.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0732510552 be used as a direct replacement for the TE Connectivity AMP 1051109-1?

A: Yes. The Molex 0732510552 meets all primary substitution criteria including connector style, type, impedance, mounting configuration, termination method, frequency rating, operating temperature range, and mating cycle specification. Both parts are SMA plug connectors with 50 ohm impedance, right-angle solder termination, and 18 GHz maximum frequency.

Q: What is the difference between the cable groups specified for these parts?

A: The TE Connectivity AMP 1051109-1 and Molex 0732510552 are both compatible with RG-402 semi-rigid cable (.141" diameter). The Cinch Connectivity Solutions 142-0693-101 is compatible with RG-405 semi-rigid cable (.086" diameter). Cable group selection depends on the specific application requirements and existing cable infrastructure.

Q: Are there material differences between the substitute parts?

A: Yes. The TE Connectivity AMP 1051109-1 features a stainless steel body with beryllium copper center contact. The Molex 0732510552 has a brass body with beryllium copper center contact. The Cinch Connectivity Solutions 142-0693-101 has a brass body with brass center contact. All three parts feature gold plating and PTFE dielectric material.

Q: What is the voltage rating difference, and does it matter?

A: The TE Connectivity AMP 1051109-1 and Cinch Connectivity Solutions 142-0693-101 are both rated at 335 V. The Molex 0732510552 is rated at 500 V. The higher voltage rating of the Molex part provides additional safety margin but does not affect compatibility in applications operating within the 335 V specification.

Q: Are all three parts RoHS compliant?

A: The TE Connectivity AMP 1051109-1 is RoHS Compliant. The Cinch Connectivity Solutions 142-0693-101 is ROHS3 Compliant. The Molex 0732510552 does not specify RoHS status. For applications requiring RoHS certification, the Cinch Connectivity Solutions 142-0693-101 provides explicit ROHS3 compliance.

Q: What is the REACH status for each part?

A: The TE Connectivity AMP 1051109-1 and Cinch Connectivity Solutions 142-0693-101 are both listed as REACH Affected. The Molex 0732510552 lists REACH status as Vendor Undefined. For applications subject to REACH regulations, clarification with the Molex vendor is recommended.

Q: Do all parts include the same accessories?

A: Yes. All three parts include 2 pieces: 1 connector and 1 end cap.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Are these parts suitable for high-frequency RF applications?

A: Yes. All three parts are rated for maximum frequency of 18 GHz and are suitable for RF coaxial applications within this frequency range.
