SF1621-60048 Equivalent & Substitute Parts

Part Overview

The SF1621-60048 is a 2.4mm (APC-2.4, OS-50) coaxial connector jack featuring a female socket configuration with 50 ohms impedance, designed for surface mount applications. This connector employs compression contact termination with screw shield termination, supporting frequencies up to 50 GHz and operating temperatures from -65°C to 165°C. The product is Active status and ROHS3 compliant. Alternative equivalent parts may be required due to inventory availability, specific dielectric material requirements, or compliance considerations across different manufacturing sources.

Key Parameters

Substitute Part Grouping Explanation

Electrical and mechanical substitution criteria for the SF1621-60048 are strictly limited to the following parameters:

Critical Electrical Parameters: Connector style (2.4mm APC-2.4, OS-50), connector type (Jack, Female Socket), impedance (50 Ohms), contact termination (Compression), frequency capability (50 GHz), operating temperature range (-65°C to 165°C), and mating cycles (500).

Critical Mechanical Parameters: Mounting type (Surface Mount), mounting feature (Flange), fastening type (Threaded), center contact material (Beryllium Copper), center contact plating (Gold), and physical dimensions compatible with 2.4mm standard.

Secondary Parameters: Shield termination method (Screw), housing color, body material composition, and regulatory compliance status.

The four substitute parts—SF1621-60029, SF1621-60049 (both Amphenol SV Microwave), 0733870022 (Molex), and 2081598-1 (TE Connectivity)—maintain all critical electrical and mechanical parameters while varying in dielectric material composition, body material specification, and regulatory compliance attributes. Each substitute maintains functional equivalence within the 2.4mm coaxial connector jack classification.

Parameter Comparison

Engineering Selection Recommendations

Amphenol SV Microwave SF1621-60029: Active product status with ROHS3 compliance and REACH Unaffected designation. Features Polyetherimide (PEI) dielectric material. Moisture Sensitivity Level 1 (Unlimited) permits unrestricted shelf life storage. Recommended where regulatory compliance streamlining and PEI dielectric specifications are required.

Amphenol SV Microwave SF1621-60049: Active product status with ROHS3 compliance and REACH Affected designation. No dielectric material specification provided. Moisture Sensitivity Level 1 (Unlimited) permits unrestricted shelf life storage. Suitable for applications where REACH compliance notification is integrated into procurement processes.

Molex 0733870022: Active product status with ROHS3 compliance and REACH Unaffected designation. Features Polytetrafluoroethylene (PTFE) dielectric material with 500 V voltage rating specification. Moisture Sensitivity Level 1 (Unlimited) permits unrestricted shelf life storage. Selection appropriate where PTFE dielectric characteristics and additional voltage rating specification align with application requirements.

TE Connectivity AMP Connectors 2081598-1: Active product status with Not Applicable RoHS designation and REACH Affected status. Operates within -55°C to 125°C temperature range, narrower than the SF1621-60048 baseline. Features Polyetherimide (PEI) dielectric material with 335 V voltage rating specification. Body material specified as Steel rather than Stainless Steel. Moisture Sensitivity Level 1 (Unlimited) permits unrestricted shelf life storage. Selection requires verification of application compatibility with reduced operating temperature range and alternative body material specification.

Frequently Asked Questions (FAQ)

Q: Can SF1621-60029, SF1621-60049, 0733870022, and 2081598-1 be used interchangeably with SF1621-60048?

A: Yes, within electrical and mechanical constraints. All parts maintain identical connector style (2.4mm APC-2.4, OS-50), connector type (Jack, Female Socket), impedance (50 Ohms), contact termination (Compression), shield termination (Screw), mounting type (Surface Mount), frequency capability (50 GHz), and mating cycles (500). Selection requires verification of operating temperature range compatibility, dielectric material requirements, and regulatory compliance status for the specific application.

Q: What is the key difference between SF1621-60048 and 2081598-1?

A: The 2081598-1 operates within a narrower temperature range (-55°C to 125°C) compared to SF1621-60048 (-65°C to 165°C). Applications requiring the full -65°C to 165°C operating temperature specification must use SF1621-60048 or alternative Amphenol or Molex parts that maintain this temperature range.

Q: Are there differences in dielectric materials among the substitute parts?

A: Yes. SF1621-60029 and 2081598-1 specify Polyetherimide (PEI) dielectric material. Molex 0733870022 specifies Polytetrafluoroethylene (PTFE) dielectric material. SF1621-60048 and SF1621-60049 do not specify dielectric material composition. Applications with specific dielectric material requirements must reference the documented specifications.

Q: What is the significance of REACH Status in the parameter comparison?

A: REACH Status indicates regulatory compliance classification. SF1621-60029 and 0733870022 are REACH Unaffected, requiring no REACH compliance documentation. SF1621-60049 and 2081598-1 are REACH Affected, requiring REACH compliance documentation be provided. Procurement processes must account for compliance documentation timelines and requirements based on REACH Status designation.

Q: Are packaging differences significant for system integration?

A: All parts are suitable for surface mount assembly. SF1621-60048, SF1621-60029, and 2081598-1 are supplied in Bag packaging. Molex 0733870022 is supplied in Bulk packaging. Inventory management and component handling procedures may require adjustment based on packaging format.

Q: What is Moisture Sensitivity Level (MSL) and why does it matter?

A: Moisture Sensitivity Level 1 (Unlimited) designation indicates the part has unlimited shelf life with no moisture control requirements during storage or handling. SF1621-60029, SF1621-60049, 0733870022, and 2081598-1 all specify MSL 1 (Unlimited), permitting standard storage practices without desiccant packaging or environmental controls.
