Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 240-J-P-EP-ST-CM-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector style must be 2.4mm (APC-2.4, OS-50)
• Impedance must be 50 Ohms
• Frequency maximum must be 50 GHz or greater
• Operating temperature range must encompass -65°C to 165°C

Mechanical Compatibility:

• Connector type must be Jack, Female Socket
• Contact termination must be Compression
• Shield termination must be Screw
• Mounting type must be Surface Mount
• Mounting feature must be Flange

Material & Construction:

• Center contact material must be Beryllium Copper
• Center contact plating must be Gold
• Body material must be Stainless Steel
• Dielectric material must be Polyetherimide (PEI) or equivalent

Regulatory & Compliance:

• RoHS3 Compliant status required
• ECCN classification EAR99
• HTSUS code 8536.69.4010

All substitute parts listed meet these criteria and are functionally interchangeable with the main part number in RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the 240-J-P-EP-ST-CM-2 across the specified operating parameters. Selection among equivalent parts should be based on the following factors:

Manufacturer Availability: The main part is manufactured by Samtec Inc., while substitute parts are manufactured by Amphenol SV Microwave. Both manufacturers produce parts meeting ROHS3 compliance and EAR99 ECCN classification.

Inventory Considerations: SF1621-60029-1S offers the highest inventory availability at 20,535 units, followed by SF1621-60026-1S at 1,919 units. The main part 240-J-P-EP-ST-CM-2 has 915 units in stock. Inventory levels should be evaluated against project lead time requirements.

Regulatory Compliance: All parts are ROHS3 compliant and classified under ECCN EAR99. REACH status varies: Samtec parts show REACH Affected or unspecified status, while Amphenol SV Microwave parts are marked REACH Unaffected or Affected depending on the specific part number. Verify REACH compliance requirements for your application jurisdiction.

Packaging & Accessories: The main part is supplied in tray packaging. Amphenol SV Microwave substitute parts include 3 pieces per package (1 connector and 2 screws), which may affect assembly and inventory management workflows.

Product Status: All parts maintain Active product status, ensuring continued availability and support from manufacturers.

Frequently Asked Questions (FAQ)

Q: Can SF1621-60029-1S be used as a direct replacement for 240-J-P-EP-ST-CM-2?

A: Yes. Both parts are 2.4mm (APC-2.4, OS-50) coaxial connector jacks with 50 Ohm impedance, compression contact termination, screw shield termination, surface mount flange mounting, and identical operating temperature ranges. All critical electrical and mechanical parameters are equivalent.

Q: What is the difference between the Samtec 240-J-P-EP-ST-CM-2 and 240-J-P-EP-ST-CMM-2?

A: Both parts are manufactured by Samtec Inc. and share identical electrical and mechanical specifications. The difference lies in the part number designation (CM-2 versus CMM-2). Both are functionally equivalent and interchangeable.

Q: Are there differences in dielectric material between substitute parts?

A: The main part and most Amphenol SV Microwave substitutes specify Polyetherimide (PEI) as the dielectric material. SF1621-60048-1S and SF1621-60049-1S do not specify dielectric material in the provided data. For applications where dielectric material specification is critical, confirm with the manufacturer before substitution.

Q: Do all substitute parts include mounting hardware?

A: The main part 240-J-P-EP-ST-CM-2 includes mounting hardware. Amphenol SV Microwave parts (SF1621 series) include 3 pieces per package: 1 connector and 2 screws. Verify that included hardware meets your assembly requirements.

Q: What is the significance of the different part number suffixes in the SF1621 series?

A: The SF1621 series uses different suffix designations (60026-1S, 60026-2S, 60029-1S, 60029-2S, 60048-1S, 60049-1S) to differentiate variants within the product line. All listed variants meet the electrical and mechanical specifications required for substitution with the main part.

Q: Are there REACH compliance considerations for international applications?

A: REACH status varies among substitute parts. Samtec 240-J-P-EP-ST-CMM-2 is marked REACH Affected. Amphenol SV Microwave parts show either REACH Affected or REACH Unaffected status depending on the specific part number. Verify REACH compliance requirements for your target market before final part selection.

Q: What is the maximum frequency rating for all substitute parts?

A: All substitute parts are rated for 50 GHz maximum frequency, matching the main part specification. This rating applies across all listed equivalents.

Q: Can these connectors be used in applications requiring higher mating cycle counts?

A: All parts, including the main part and substitutes, are rated for 500 mating cycles. Applications requiring higher cycle counts require evaluation of alternative connector designs outside this product category.
