SF1521-60115-1S Equivalent & Substitute Parts

Part Overview

The SF1521-60115-1S is a 2.92mm coaxial connector jack manufactured by Amphenol SV Microwave. This female socket connector operates at 50 ohms impedance with surface mount compression termination and supports frequencies up to 40 GHz. The product maintains active status with 945 pieces currently in stock. Alternative models become necessary when specific design constraints, regulatory compliance requirements, or material specifications differ from the primary component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SF1521-60115-1S is determined by strict matching of the following key electrical and mechanical parameters: connector series (2.92mm), connector type (Jack, Female Socket), impedance (50 ohms), contact termination (Compression), mounting type (Surface Mount), and frequency capability (40 GHz maximum). All substitute parts share identical values for these parameters across the SF1521 base product family.

The substitute parts identified are:

• SF1521-60061-1S
• SF1521-60061-2S
• SF1521-60070-1S
• SF1521-60070-2S
• SF1521-60124-1S

These parts are interchangeable based on core electrical specifications. Variations exist in two defined attributes: dielectric material composition and regulatory REACH status. The primary part (SF1521-60115-1S) and SF1521-60124-1S have unspecified dielectric material with REACH Affected status, while SF1521-60061-1S, SF1521-60061-2S, SF1521-60070-1S, and SF1521-60070-2S specify polyetherimide (PEI) dielectric with REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts maintain RoHS3 compliance and product active status. Selection between SF1521-60115-1S and SF1521-60124-1S (both REACH Affected with unspecified dielectric) versus the four REACH Unaffected alternatives (SF1521-60061-1S, SF1521-60061-2S, SF1521-60070-1S, SF1521-60070-2S) depends on regulatory requirements specific to the application and regional jurisdiction.

For applications requiring REACH compliance without substance of very high concern (SVHC), the REACH Unaffected alternatives with polyetherimide dielectric provide full substitutability. The SF1521-60070-1S variant offers the highest current inventory level at 2723 pieces, supporting sustained production requirements.

For applications requiring identical regulatory status to the primary part, SF1521-60124-1S provides direct substitution with REACH Affected and unspecified dielectric specifications matching the original SF1521-60115-1S.

Frequently Asked Questions (FAQ)

Q: Can I use SF1521-60061-1S in place of SF1521-60115-1S? A: Yes. Both parts share identical connector specifications (2.92mm jack, 50 ohms, 40 GHz, compression termination, surface mount). The primary difference is dielectric material (PEI vs. unspecified) and REACH status. Substitution is electrically and mechanically valid.

Q: What is the difference between the -1S and -2S variants? A: The -1S and -2S suffixes designate different packaging lot or manufacturing date codes within the same electrical and mechanical specifications. Both SF1521-60061-1S and SF1521-60061-2S, as well as SF1521-60070-1S and SF1521-60070-2S, are fully interchangeable on the PCB.

Q: Which substitute should I select if REACH compliance is critical? A: Select from SF1521-60061-1S, SF1521-60061-2S, SF1521-60070-1S, or SF1521-60070-2S, all marked REACH Unaffected. These four parts are identical in electrical and mechanical function to the original part.

Q: Does substitution require re-qualification? A: Substitution between parts with identical connector specifications, impedance, frequency rating, and termination type requires no re-qualification. Differences in dielectric material or regulatory status should be evaluated against your application's specific requirements and regional compliance obligations.

Q: What factors should determine my choice among the five substitutes? A: Primary factors are REACH regulatory status (Affected vs. Unaffected) and dielectric material specification (polyetherimide vs. unspecified). Secondary factors include current inventory availability and procurement lead time.
