TE Connectivity AMP Connectors 1053770-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1053770-1 is an adapter coaxial connector designed to convert between SSMA Plug (Male Pin) and SMA Jack (Female Socket) configurations. This component operates at 50 Ohms impedance with a maximum frequency rating of 25 GHz and supports operating temperatures from -65°C to 125°C. The part is classified as Obsolete, necessitating identification of active equivalent components for ongoing procurement and system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1053770-1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Jack configuration
• Impedance: 50 Ohms
• Center Contact Plating: Gold
• Body Material: Stainless Steel
• Dielectric Material: PTFE
• Fastening Type: Threaded connections
• Mounting Type: Free Hanging (In-Line)
• Style: Straight

Functional Compatibility Criteria: The primary substitute, Amphenol SV Microwave SF2997-6003, maintains the core adapter functionality (Plug to Jack) and all mandatory electrical parameters. However, this substitute operates at a maximum frequency of 18 GHz compared to the original part's 25 GHz specification. The substitute converts between SMA series connectors (SMA to SMA) rather than the original SSMA to SMA conversion. This represents a same-series adapter configuration versus the original between-series conversion.

Parameter Comparison

Engineering Selection Recommendations

Original Part Status: The TE Connectivity 1053770-1 is classified as Obsolete. While inventory remains available (97,800 pieces), the obsolete designation indicates discontinued manufacturing and potential long-term supply constraints.

Substitute Part Viability: The Amphenol SV Microwave SF2997-6003 is an Active product with current manufacturing support. This substitute maintains RoHS and REACH compliance requirements, with ROHS3 certification providing enhanced regulatory alignment. The substitute is suitable for applications where the maximum frequency requirement does not exceed 18 GHz.

Selection Criteria:

• For applications requiring frequencies above 18 GHz, the original 1053770-1 specification must be maintained due to its 25 GHz maximum frequency rating.
• For applications operating at or below 18 GHz, the SF2997-6003 substitute provides equivalent electrical performance with the advantage of active product status and ongoing manufacturer support.
• Both parts maintain identical impedance (50 Ohms), connector gender configuration, and material specifications.

Frequently Asked Questions (FAQ)

Q: Can the SF2997-6003 directly replace the 1053770-1 in all applications?

A: Direct replacement is possible only for applications where the maximum operating frequency does not exceed 18 GHz. The original part supports frequencies up to 25 GHz. If your system operates above 18 GHz, the original specification must be retained.

Q: What is the primary difference between these two adapters?

A: The original 1053770-1 converts between SSMA and SMA series connectors (between-series conversion), while the SF2997-6003 converts between two SMA connectors (same-series conversion). Both maintain identical 50 Ohm impedance and Plug-to-Jack adapter functionality.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The substitute (SF2997-6003) carries ROHS3 certification, representing a more current compliance standard. Both parts are REACH affected/unaffected as specified in their respective documentation.

Q: What is the mating cycle rating for each part?

A: The original 1053770-1 does not specify a mating cycle rating. The substitute SF2997-6003 is rated for 500 mating cycles.

Q: How do the packaging options differ?

A: The original part packaging is not specified. The substitute is supplied in Bulk packaging.

Q: Are the physical dimensions and mounting configurations identical?

A: Both parts feature Straight style, Free Hanging (In-Line) mounting type, and Threaded fastening. Physical compatibility is maintained for in-line adapter applications.

Q: What inventory considerations should be evaluated?

A: The original part has substantial inventory (97,800 pieces), while the substitute has limited availability (1,611 pieces). For long-term procurement planning, the active status of the substitute provides ongoing supply assurance despite lower current stock levels.
