Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1045746-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter type: Plug to Jack configuration
• Connector series: SSMA (OSSM designation)
• Gender conversion: Male pin to female socket
• Impedance: 50 ohms
• Style: Right angle
• Mounting configuration: Free hanging (in-line) with right angle capability
• Fastening mechanism: Threaded connections
• Frequency capability: 18 GHz maximum
• Material composition: Stainless steel body with beryllium copper center contact and PTFE dielectric
• Contact plating: Gold
• Operating temperature range: -65°C to 165°C

The substitute part 1045747-1 maintains full electrical and mechanical compatibility with the original 1045746-1 across all specified parameters, with the distinction that 1045747-1 carries active product status and enhanced compliance certifications.

Engineering Selection Recommendations

The TE Connectivity 1045747-1 serves as the direct functional equivalent for the obsolete 1045746-1. Selection of 1045747-1 is supported by the following engineering considerations:

Product Status: The substitute part 1045747-1 maintains active product status, ensuring continued availability and manufacturer support. The original 1045746-1 is classified as obsolete, limiting future procurement options.

Compliance Certifications: Part 1045747-1 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in aerospace, defense, and marine applications. This certification status provides assurance of compliance with environmental and hazardous substance restrictions.

Electrical and Mechanical Equivalence: All critical electrical parameters (impedance, frequency capability, center contact materials, dielectric composition) and mechanical parameters (adapter configuration, mounting type, fastening mechanism, body materials) are identical between the two parts.

Material and Construction: Both parts utilize identical materials—stainless steel body, beryllium copper center contact, and PTFE dielectric—ensuring equivalent performance characteristics across the specified operating temperature range of -65°C to 165°C.

Regulatory Classification: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, indicating no change in export control or tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can 1045747-1 be used as a direct replacement for 1045746-1 in existing designs?

A: Yes. The 1045747-1 maintains identical electrical and mechanical specifications across all critical parameters including impedance, frequency response, connector gender configuration, mounting style, and material composition. Direct substitution is supported without design modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certifications. The 1045746-1 is obsolete, while 1045747-1 is active. Additionally, 1045747-1 carries ROHS3 compliance certification and specifies Moisture Sensitivity Level 1 (Unlimited), whereas 1045746-1 lists MSL as Not Applicable. Both parts are functionally equivalent.

Q: Are there any packaging differences between these parts?

A: The 1045747-1 is specified as available in bulk packaging. The original 1045746-1 packaging specification is not provided in the technical data. Bulk packaging of the substitute part may offer advantages for high-volume procurement applications.

Q: Does the ROHS3 compliance of 1045747-1 affect compatibility?

A: No. ROHS3 compliance indicates adherence to restrictions on hazardous substances and is a regulatory requirement rather than a functional specification. This certification enhances the substitute part's suitability for applications subject to environmental compliance requirements.

Q: Are the operating temperature ranges equivalent?

A: The original 1045746-1 specifies an operating temperature range of -65°C to 165°C. The 1045747-1 does not provide an explicit operating temperature specification in the available technical data. The original specification range applies to the functional requirements of this adapter type.

Q: What does the Moisture Sensitivity Level designation mean?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture absorption during storage and handling. The 1045747-1 carries MSL 1 (Unlimited), indicating minimal moisture sensitivity and flexible storage and handling requirements. The original part lists MSL as Not Applicable, indicating no moisture sensitivity concern for this connector type.

Q: Are both parts suitable for aerospace, defense, and marine applications?

A: Yes. Both parts are manufactured by TE Connectivity Aerospace, Defense and Marine and carry identical ECCN (EAR99) and HTSUS classifications appropriate for these application domains. The 1045747-1 offers the additional advantage of active product status and current compliance certifications.
