SF1521-60070-2S Equivalent & Substitute Parts
Part Overview
The SF1521-60070-2S is a 2.92mm coaxial connector jack from Amphenol SV Microwave, designed for surface mount applications requiring 50 ohm impedance and frequency performance to 40 GHz. This female socket connector features compression contact termination and is currently in active production status. Equivalent substitute parts are necessary when primary inventory is unavailable, when supply chain optimization is required, or when procurement sourcing benefits from multiple qualified vendors within the same electrical and mechanical parameter class.

Engineering Selection Recommendations
All qualified substitute parts (SF1521-60061-1S, SF1521-60061-2S, SF1521-60070-1S, and SF1521-60124-1S) are manufactured by Amphenol SV Microwave with ROHS3 compliance and active product status, ensuring regulatory alignment and manufacturing continuity.
SF1521-60070-1S offers highest available inventory at 2723 units, providing supply security for large-scale production requirements. SF1521-60061-2S maintains strong inventory levels at 1165 units. All substitute parts meet identical electrical specifications for RF circuit performance and thermal cycling requirements, warranting direct substitution without circuit redesign.
SF1521-60124-1S is qualified as a functional equivalent with the exception that dielectric material specification is not provided. Acceptance of this part requires internal assessment against application-specific RF loss and impedance stability requirements.
Frequently Asked Questions (FAQ)
Q: Are all listed substitute parts true electrical equivalents? All substitute parts maintain identical critical RF electrical parameters including 50 ohm impedance, 40 GHz frequency performance, compression contact termination, and operating temperature range of -65°C to 165°C. Direct substitution is permissible without circuit performance degradation.
Q: What distinguishes the various part numbers? The part number suffix designates packaging configuration and internal mechanical variations within the 2.92mm jack form factor. Suffixes such as -1S and -2S indicate different packaging quantities per tray or connector internal construction details; however, mating interface and RF performance remain equivalent.
Q: Can SF1521-60124-1S be used without additional qualification? SF1521-60124-1S meets all specified electrical and mechanical parameters. The dielectric material field is not specified in available documentation. If dielectric material selection is critical to application performance, material confirmation from the manufacturer is necessary before substitution.
Q: Are there temperature or frequency limitations for substitution? All substitute parts operate across the identical temperature range (-65°C to 165°C) and frequency range (DC to 40 GHz). No environmental or operational limitations restrict interchangeability.
Q: What packaging considerations apply? All parts are supplied in tray packaging with identical connector and fastener inclusion (1 connector, 2 screws per unit). Assembly and procurement procedures remain unchanged regardless of substitute selection.
