Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Preci-Dip 116-87-308-41-006101 and Mill-Max 210-43-308-41-001000 are the preferred substitutes. Both maintain the full operating temperature range of -55°C ~ 125°C, matching the original specification. The Preci-Dip part is ROHS3 compliant with active product status. The Mill-Max 210-43-308-41-001000 offers closed-frame construction identical to the original and is ROHS3 compliant with active status.

Secondary Substitutes (Temperature Derating Required):

The 3M 4808-3000-CP and 4808-3004-CP, along with the Assmann A 08-LC-TT, operate at reduced maximum temperatures (-25°C ~ 85°C for 3M parts; -55°C ~ 85°C for Assmann). These substitutes are suitable only for applications where the operating environment does not exceed 85°C. All three are ROHS3 compliant with active product status.

Compliance Considerations:

For applications requiring ROHS3 compliance, the following parts are suitable: Preci-Dip 116-87-308-41-006101, Mill-Max 210-43-308-41-001000, 3M 4808-3000-CP, 3M 4808-3004-CP, and Assmann A 08-LC-TT. The Mill-Max 116-93-308-41-006000 is RoHS non-compliant and should be selected only when legacy compliance requirements are specified.

Contact Finish Considerations:

Gold-plated mating contacts (Preci-Dip 116-87-308-41-006101, Mill-Max 116-93-308-41-006000, and Mill-Max 210-43-308-41-001000) provide direct electrical equivalence to the original. Tin-plated alternatives (3M and Assmann parts) are functionally equivalent for standard DIP socket applications but differ in contact material composition.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4808-3004-CP be used as a direct replacement for the TE Connectivity 2-640463-2?

A: The 3M 4808-3004-CP is mechanically and electrically compatible for through-hole PCB mounting and solder termination. However, it operates at a maximum temperature of 85°C, compared to the original specification of 125°C. Selection depends on the application's thermal environment. If the circuit operates below 85°C, this part is suitable. If sustained operation above 85°C is required, the Preci-Dip 116-87-308-41-006101 or Mill-Max 210-43-308-41-001000 are required.

Q: What is the difference between gold-plated and tin-plated contact finishes in DIP sockets?

A: Both gold and tin finishes provide adequate electrical conductivity for DIP socket applications. Gold plating offers superior corrosion resistance and lower contact resistance (30mOhm for the original versus unspecified for tin-plated alternatives). Tin plating is cost-effective and suitable for standard industrial applications. Selection between them depends on environmental exposure and contact resistance requirements.

Q: Are the Preci-Dip and Mill-Max substitutes pin-compatible with the original TE Connectivity part?

A: Yes. All substitute parts maintain identical pitch specifications (0.100" mating and post pitch) and 8-position (2 x 4) configuration. PCB footprints and component insertion are directly compatible. Physical differences in frame design (open versus closed) do not affect electrical or mechanical compatibility.

Q: Which substitute part offers the best long-term availability?

A: The 3M 4808-3004-CP has the highest inventory level (53,828 pieces) and active product status, indicating strong market availability. The Mill-Max 210-43-308-41-001000 (2,111 pieces) and Assmann A 08-LC-TT (7,113 pieces) also demonstrate active production. All three are suitable for long-term supply chain planning.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is mandatory for products sold in the European Union and many other regulated markets. If your application requires ROHS3 certification, select from: Preci-Dip 116-87-308-41-006101, Mill-Max 210-43-308-41-001000, 3M 4808-3000-CP, 3M 4808-3004-CP, or Assmann A 08-LC-TT. The Mill-Max 116-93-308-41-006000 is RoHS non-compliant and unsuitable for regulated applications.

Q: What is the significance of the closed-frame versus open-frame design?

A: The original TE Connectivity 2-640463-2 features a closed-frame design. The Mill-Max 210-43-308-41-001000 maintains this design. Preci-Dip 116-87-308-41-006101 and the 3M and Assmann parts use open-frame designs. Both designs provide equivalent electrical performance and mechanical stability for standard DIP component insertion. Frame design selection depends on PCB layout preferences and mechanical support requirements.

Q: Can I use the Assmann A 08-LC-TT in applications requiring the full -55°C to 125°C temperature range?

A: No. The Assmann A 08-LC-TT operates from -55°C to 85°C, limiting its maximum temperature to 85°C. For applications requiring sustained operation above 85°C, use the Preci-Dip 116-87-308-41-006101 or Mill-Max 210-43-308-41-001000, both rated to 125°C.
