Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-641616-1 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 40 (2 x 20)
• Type: DIP with 0.6" (15.24mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder

Acceptable Variation Parameters:

• Contact Finish - Mating: Tin or Gold (both provide electrical continuity)
• Contact Material - Mating: Beryllium Copper or Phosphor Bronze (both acceptable for DIP sockets)
• Contact Material - Post: Beryllium Copper, Phosphor Bronze, or Brass Alloy (all suitable for solder termination)
• Operating Temperature Range: Must encompass or exceed the application requirement
• Housing Material: Thermoplastic, Polyester, Glass Filled, or Polycyclohexylenedimethylene Terephthalate (PCT)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant preferred for new designs
• Material Flammability Rating: UL94 V-0 required
• Moisture Sensitivity Level: 1 (Unlimited) standard for all candidates

Five substitute parts meet these criteria across three manufacturers: 3M, Mill-Max Manufacturing Corp., and Assmann WSW Components.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

The 3M 4840-6004-CP and 4840-6000-CP are direct functional equivalents with active product status and ROHS3 compliance. Both feature identical 40-position DIP configuration with 0.6" row spacing and tin contact finish. The 3M 4800 series uses phosphor bronze contact material instead of beryllium copper, which is acceptable for DIP socket applications. Operating temperature range of -25°C to 85°C is suitable for standard industrial applications; however, applications requiring the full -55°C to 105°C range of the original part require alternative selection.

The Assmann WSW Components A 40-LC-TR provides tin contact finish with phosphor bronze material and maintains the -55°C to 85°C operating range. This part offers compatibility with temperature-sensitive applications while maintaining ROHS3 compliance and active product status.

Secondary Substitutes (Gold Contact Finish):

The Mill-Max Manufacturing Corp. 116-41-640-41-006000, 116-91-640-41-006000, and 116-93-640-41-006000 are elevated DIP sockets with gold contact finish on mating contacts. These parts provide superior contact reliability and lower contact resistance (10mOhm versus 30mOhm). The 116-41 and 116-91 variants maintain full ROHS3 compliance and extended operating temperature range (-55°C to 125°C). The 116-93 variant is RoHS non-compliant and should not be selected for new designs requiring regulatory compliance.

Temperature Considerations:

Applications operating at temperatures below -25°C or above 85°C should select the Assmann A 40-LC-TR (-55°C to 85°C) or Mill-Max 116 series (-55°C to 125°C) to ensure reliable operation within specified thermal limits.

Compliance Requirements:

All recommended substitutes maintain ROHS3 compliance except the Mill-Max 116-93-640-41-006000. For applications subject to RoHS regulations, exclude the 116-93 variant from selection.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4840-6004-CP directly replace the TE Connectivity 2-641616-1?

A: Yes. Both parts share identical 40-position DIP configuration, 0.6" row spacing, 0.100" pitch, through-hole solder termination, and UL94 V-0 flammability rating. The primary difference is contact material (phosphor bronze versus beryllium copper), which does not affect functional compatibility. Operating temperature range differs (-25°C to 85°C versus -55°C to 105°C); verify application temperature requirements before selection.

Q: What is the difference between tin and gold contact finishes?

A: Tin contact finish (2-641616-1, 4840-6004-CP, 4840-6000-CP, A 40-LC-TR) provides standard electrical continuity with lower cost. Gold contact finish (Mill-Max 116 series) offers enhanced corrosion resistance and lower contact resistance (10mOhm versus 30mOhm), beneficial for low-signal applications or high-reliability requirements. Both finishes are electrically compatible with standard DIP integrated circuits.

Q: Are the Mill-Max elevated sockets compatible with standard DIP packages?

A: Yes. The Mill-Max 116 series elevated sockets accommodate standard 40-position DIP packages with 0.6" row spacing and 0.100" pitch. The elevated design provides additional clearance above the printed circuit board, which may be beneficial in applications with component density constraints or thermal management requirements.

Q: What does "open frame" mean in socket design?

A: Open frame indicates the socket lacks a full plastic housing around the contact array. This design reduces material cost and weight while maintaining electrical function. All substitute parts listed feature open frame construction, consistent with the original 2-641616-1.

Q: Which substitute offers the lowest contact resistance?

A: The Mill-Max 116-41-640-41-006000 and 116-91-640-41-006000 provide 10mOhm contact resistance, compared to 30mOhm for the original part and Assmann A 40-LC-TR. Lower contact resistance reduces voltage drop and heat generation in high-current applications.

Q: Is the Mill-Max 116-93-640-41-006000 suitable for new product designs?

A: No. The 116-93 variant is RoHS non-compliant, making it unsuitable for applications subject to RoHS regulations or customer requirements. Select the RoHS3-compliant 116-41 or 116-91 variants instead.

Q: What is the difference between the Mill-Max 116-41, 116-91, and 116-93 variants?

A: All three are 40-position DIP sockets with identical electrical specifications. The primary differences are post contact finish (tin for 116-41, tin-lead for 116-91 and 116-93) and RoHS compliance status (116-41 and 116-91 are ROHS3 compliant; 116-93 is non-compliant). For new designs, select the 116-41 variant.

Q: Can I use a substitute with a lower operating temperature range?

A: Only if your application operates within the substitute's specified temperature range. The 3M 4840 series (-25°C to 85°C) is suitable for standard industrial applications. For applications requiring -55°C operation, select the Assmann A 40-LC-TR or Mill-Max 116 series.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts are supplied in tube packaging, consistent with standard DIP socket distribution. The original TE Connectivity 2-641616-1 packaging is not specified in available data.
