Key Parameters

Substitute Part Grouping Explanation

Substitution for the TE Connectivity 2-641611-1 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of Positions: 18 (2 x 9)
• Type: DIP with 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder

Allowable Variations:

• Contact Finish - Mating: Tin or Gold (both provide electrical conductivity)
• Contact Material - Mating: Beryllium Copper or Phosphor Bronze (both provide spring force and conductivity)
• Housing Material: Thermoplastic, Polybutylene Terephthalate (PBT), or Polycyclohexylenedimethylene Terephthalate (PCT) Polyester
• Operating Temperature Range: Minimum -55°C, Maximum 85°C or higher
• Contact Resistance: 30mOhm or lower
• RoHS Compliance: ROHS3 Compliant or equivalent

The substitute parts listed below meet these criteria and are suitable for direct replacement in applications requiring 18-position DIP sockets with standard 0.100" pitch and through-hole termination.

Engineering Selection Recommendations

Assmann WSW A 18-LC-TT (Direct Equivalent)

The Assmann WSW A 18-LC-TT is the primary substitute for the obsolete TE Connectivity 2-641611-1. This part maintains identical electrical and mechanical specifications including 18-position DIP configuration, 0.100" pitch, tin contact finish, and 30mOhm contact resistance. The A 18-LC-TT is ROHS3 compliant and carries active product status, ensuring long-term availability. The operating temperature range of -55°C to 85°C covers standard industrial applications. This substitute is suitable for direct replacement in new designs and field service applications.

Mill-Max 116-93-318-41-006000 (Alternative Substitute)

The Mill-Max 116-93-318-41-006000 provides an alternative substitute with enhanced operating temperature capability (-55°C to 125°C) and gold contact finish on the mating side. This part maintains the critical 18-position DIP configuration and 0.100" pitch specifications. However, this substitute carries RoHS non-compliant status, which may restrict its use in applications subject to RoHS regulations. The gold contact finish provides superior corrosion resistance compared to tin, making it suitable for harsh environmental conditions or applications requiring extended contact life. Selection of this part requires verification of RoHS compliance requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can the Assmann WSW A 18-LC-TT be used as a direct replacement for the TE Connectivity 2-641611-1?

A: Yes. Both parts share identical pin counts (18 positions), row spacing (0.3"), pitch specifications (0.100"), contact finish (tin), mounting type (through hole), and contact resistance (30mOhm). The A 18-LC-TT is ROHS3 compliant and maintains active product status, making it suitable for direct replacement in applications operating within the -55°C to 85°C temperature range.

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

A: The TE Connectivity 2-641611-1 and Assmann WSW A 18-LC-TT feature tin contact finish on the mating side. The Mill-Max 116-93-318-41-006000 features gold contact finish on the mating side. Gold provides superior corrosion resistance and lower contact resistance degradation over time, particularly in humid or corrosive environments. Tin is suitable for standard indoor applications with controlled environmental conditions.

Q: Are there temperature limitations when substituting these parts?

A: The TE Connectivity 2-641611-1 operates from -55°C to 105°C. The Assmann WSW A 18-LC-TT operates from -55°C to 85°C, which covers most standard industrial applications but may not be suitable for high-temperature applications exceeding 85°C. The Mill-Max 116-93-318-41-006000 operates from -55°C to 125°C, providing extended high-temperature capability. Selection should be based on the specific application temperature requirements.

Q: What is the significance of RoHS compliance status?

A: The TE Connectivity 2-641611-1 and Assmann WSW A 18-LC-TT are ROHS3 compliant, meeting European Union restrictions on hazardous substances. The Mill-Max 116-93-318-41-006000 is RoHS non-compliant. Applications subject to RoHS regulations, including products sold in the European Union or to regulated industries, must use ROHS3 compliant substitutes. The Assmann WSW A 18-LC-TT is the appropriate choice for RoHS-regulated applications.

Q: What is the difference in contact material between the substitutes?

A: The TE Connectivity 2-641611-1 uses beryllium copper for both mating and post contacts. The Assmann WSW A 18-LC-TT uses phosphor bronze for both mating and post contacts. The Mill-Max 116-93-318-41-006000 uses beryllium copper for mating contacts and brass alloy for post contacts. All three materials provide adequate spring force and electrical conductivity for DIP socket applications. Contact material selection does not affect interchangeability for standard IC socket applications.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. All three parts share identical 18-position DIP configuration, 0.3" row spacing, and 0.100" pitch specifications. They are mechanically and electrically interchangeable on printed circuit boards designed for standard 18-pin DIP packages. No PCB redesign is required when substituting between these parts.

Q: What packaging formats are available for these substitutes?

A: The TE Connectivity 2-641611-1 packaging format is not specified in the available data. The Assmann WSW A 18-LC-TT is supplied in tube packaging. The Mill-Max 116-93-318-41-006000 is supplied in tube packaging. Tube packaging is standard for DIP socket components and is suitable for both manual and automated assembly processes.
