Key Parameters

Substitute Part Grouping Explanation

The Amphenol RF 262105 qualifies as a parametric equivalent to the Molex 0734155261 based on matching electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

Connector style (MMCX), connector type (jack, female socket), impedance (50 ohms), mounting configuration (through hole, right angle), contact and shield termination method (solder), frequency rating (6 GHz maximum), fastening mechanism (snap-on), voltage rating (170 V), mating cycle rating (500), center contact material (beryllium copper), body material (brass), dielectric material (PTFE), and housing color (gold) are identical across both parts.

Operating temperature range for the substitute part is not specified in available documentation but does not preclude functional equivalence for applications within the main part's rated range. Both parts carry the same ECCN and HTSUS classifications, confirming regulatory alignment for coaxial RF connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0734155261 and Amphenol RF 262105 are active production parts suitable for MMCX RF connector applications. Selection between these parts should be based on compliance requirements and regulatory status.

The Molex 0734155261 is RoHS non-compliant, making it appropriate for applications where RoHS compliance is not mandated or where legacy system compatibility is required.

The Amphenol RF 262105 is ROHS3 compliant and REACH affected, making it the appropriate choice for applications subject to European Union environmental directives or customer specifications requiring RoHS3 compliance. Both parts share identical electrical and mechanical specifications, ensuring functional interchangeability within their respective compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 262105 be used as a direct replacement for the Molex 0734155261?

A: Yes, from an electrical and mechanical standpoint. Both parts are MMCX jack connectors with identical impedance (50 ohms), frequency rating (6 GHz), mounting configuration (through hole, right angle), and termination method (solder). The primary difference is RoHS compliance status. Verify that your application's compliance requirements align with the substitute part's certification before implementation.

Q: What is the difference in RoHS compliance between these parts?

A: The Molex 0734155261 is RoHS non-compliant, while the Amphenol RF 262105 is ROHS3 compliant. ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive as amended. Applications requiring RoHS3 certification must use the Amphenol RF part.

Q: Are the packaging formats compatible?

A: The Molex 0734155261 packaging format is not specified in available documentation. The Amphenol RF 262105 is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts support the same operating temperature range?

A: The Molex 0734155261 operates from -55°C to 165°C. The operating temperature range for the Amphenol RF 262105 is not specified in available documentation. For applications requiring operation across the full -55°C to 165°C range, confirm the substitute part's temperature specifications with the manufacturer.

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

A: Both parts are rated for 500 mating cycles, indicating equivalent mechanical durability for snap-on fastening applications.
