110-13-314-41-801000
110-43-314-41-605000
110-43-314-41-801000
116-43-314-41-001000
116-43-314-41-003000
116-43-314-41-006000
116-43-314-41-007000
116-43-314-41-008000

All listed parts maintain active product status from Mill-Max Manufacturing Corp., ensuring long-term availability and supply chain stability.

Selection by Termination Post Length:

The 2-641609-1 features a termination post length of 0.120" (3.05mm). Substitute parts with comparable post lengths include:

110-13-314-41-801000: 0.125" (3.18mm)
110-43-314-41-605000: 0.125" (3.18mm)
110-43-314-41-801000: 0.125" (3.18mm)
110-93-314-41-605000: 0.125" (3.18mm)
110-93-314-41-801000: 0.125" (3.18mm)

The 116 series parts feature elevated designs with longer post lengths (0.108" to 0.594"), suitable for applications requiring increased clearance or specific PCB stack-up configurations.

Contact Finish Considerations:

The original part features tin contact finish on both mating and post surfaces. All substitute parts feature gold mating contact finish, which provides superior corrosion resistance and contact reliability compared to tin. Post finishes vary between tin, tin-lead, and brass alloy, all compatible with solder termination processes.

Operating Temperature Range:

All substitute parts support an operating temperature range of -55°C ~ 125°C, exceeding the original part's -55°C ~ 105°C specification. This provides additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the 2-641609-1 be directly replaced with any of the listed Mill-Max substitutes?

A: Yes, all listed Mill-Max parts are direct functional substitutes. They share identical pin count (14), pitch (0.100"), row spacing (0.3"), mounting type (through-hole), and termination method (solder). The primary differences are contact finish (gold versus tin), post material composition, and termination post length. Selection depends on specific application requirements and PCB design parameters.

Q: What is the significance of the gold contact finish on substitute parts?

A: Gold contact finish on the mating surface provides enhanced corrosion resistance and improved contact reliability compared to tin. Gold does not oxidize under normal environmental conditions, ensuring consistent electrical performance over extended service life. This is particularly beneficial in applications subject to thermal cycling or high-humidity environments.

Q: How do the 110 and 116 series differ?

A: The 110 series features standard-height socket designs with termination post lengths of 0.125" (3.18mm). The 116 series features elevated socket designs with variable post lengths ranging from 0.108" to 0.594", accommodating applications requiring increased clearance between the socket and PCB surface or specific component stacking configurations.

Q: Are there RoHS compliance differences among the substitute parts?

A: Yes. Parts 110-93-314-41-605000 and 110-93-314-41-801000 are RoHS non-compliant due to tin-lead post finish. All other listed substitutes are ROHS3 compliant. For applications subject to RoHS regulations, select from the ROHS3-compliant options.

Q: What is the contact resistance specification for the substitute parts?

A: The original 2-641609-1 specifies 30mOhm contact resistance. Several substitute parts specify 10mOhm contact resistance (110-43-314-41-605000, 116-43-314-41-001000, 116-43-314-41-003000, 116-43-314-41-007000, 116-43-314-41-008000), providing superior electrical performance. Parts without specified contact resistance are electrically equivalent for standard applications.

Q: How should termination post length be selected?

A: Termination post length selection depends on PCB thickness and component stacking requirements. The original part specifies 0.120" (3.05mm). Standard 110 series substitutes provide 0.125" (3.18mm), suitable for most applications. The 116 series offers variable lengths: 0.108" (2.74mm) for minimal clearance, 0.315" (8.00mm) for moderate elevation, 0.402" (10.21mm) for increased clearance, 0.472" (11.99mm) for high elevation, and 0.594" (15.09mm) for maximum elevation. Verify PCB design requirements before selection.

Q: Is the operating temperature range difference significant?

A: The original part operates from -55°C to 105°C. All substitute parts operate from -55°C to 125°C, providing an additional 20°C upper temperature margin. This enhanced specification does not affect substitution compatibility and provides additional thermal headroom for demanding applications.

Q: What is the current rating for these DIP sockets?

A: All Mill-Max substitute parts are rated for 3 A per contact. The original 2-641609-1 does not specify a current rating. The 3 A rating of substitute parts is suitable for standard DIP IC applications and does not impose additional design constraints.

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

A: All substitute parts are supplied in tube packaging. The original 2-641609-1 packaging specification is not provided. Tube packaging is standard for DIP socket distribution and is compatible with automated assembly processes.
