3M 100-008-050 DIP Socket 8-Position Equivalent & Substitute Parts

Part Overview

The 3M 100-008-050 is an 8-position DIP socket with 0.3" (7.62mm) row spacing, gold-plated beryllium copper mating contacts, and solder termination. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The socket accommodates standard 8-pin DIP integrated circuits with 0.100" (2.54mm) pitch and is rated for 1 A continuous current across the -65°C to 125°C operating temperature range. The through-hole solder termination and open frame design provide direct PCB integration for legacy and new applications requiring DIP socket functionality.

Substitute Part Grouping Explanation

Substitution of the 3M 100-008-050 is determined by strict equivalence in the following critical parameters:

Position Count & Row Spacing: All substitutes must be 8-position (2 x 4) DIP sockets with 0.3" (7.62mm) row spacing
Pitch Specifications: Mating pitch and post pitch must both be 0.100" (2.54mm)
Contact Material - Mating: Beryllium copper is the required mating contact material
Mounting & Termination: Through-hole solder termination is mandatory
Electrical Performance: Current rating must meet or exceed 1 A

Substitute parts are grouped by contact finish configuration (gold, tin, or tin-lead) and housing material composition. All listed substitutes maintain mechanical and electrical compatibility with the original 3M 100-008-050 footprint and function.

Engineering Selection Recommendations

Primary Recommendation for Active Production:

110-43-308-41-001000 (Mill-Max Series 110) is the preferred substitute. This part maintains solder termination compatibility with the original 3M 100-008-050, provides 3 A current capacity (exceeding the 1 A requirement), and is actively manufactured. The gold-plated beryllium copper mating contacts ensure electrical performance equivalent to the original. ROHS3 compliance and REACH unaffected status support modern supply chain requirements.

Alternative for Gold Contact Finish with Extended Post Length:

111-91-308-41-001000 (Mill-Max Series 111) provides identical electrical and mechanical specifications to 110-43-308-41-001000 with an extended post length of 0.170" (4.32mm) versus 0.125" (3.18mm). This variant accommodates applications requiring deeper PCB penetration or thicker board assemblies. Contact resistance is specified at 10 mOhm.

Tin-Lead Finish Option (Non-RoHS):

110-99-308-41-001000 maintains full mechanical and electrical compatibility with tin-lead mating and post finishes. This part is suitable for legacy applications where tin-lead compatibility is required. RoHS non-compliance status must be evaluated against design and procurement standards.

Tin Finish Option (RoHS Compliant):

110-44-308-41-001000 provides tin-plated mating contacts with ROHS3 compliance. This configuration is suitable for applications where lead-free soldering processes are mandated.

Press-Fit Termination Alternative:

104-13-308-41-770000 (Mill-Max Series 104) offers press-fit termination instead of solder. This part is appropriate for automated assembly environments where press-fit insertion is preferred over wave or reflow soldering. Operating temperature range is not specified for this variant.

Obsolete Status Consideration:

110-83-308-41-530000 is classified as obsolete and should not be selected for new designs despite active inventory availability. This part is listed for reference only in legacy system support scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 3M 100-008-050 be directly replaced with any Mill-Max substitute?

A: Yes, all listed Mill-Max substitutes maintain the same 8-position DIP configuration, 0.3" row spacing, 0.100" pitch, beryllium copper mating contacts, and through-hole solder termination. Mechanical and electrical compatibility is assured across all active substitutes.

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

A: Contact finish affects solderability and corrosion resistance. Gold finishes (110-43, 110-93, 111-43, 111-93) provide superior corrosion resistance and are preferred for long-term storage and harsh environments. Tin finishes (110-44) are RoHS compliant and suitable for lead-free assembly. Tin-lead finishes (110-99, 110-93, 111-91, 111-93) are non-compliant with RoHS regulations but may be required for legacy applications.

Q: Does the post length difference affect PCB compatibility?

A: Post length variations (0.125" to 0.175") do not affect electrical function but may impact PCB assembly processes. Longer posts (111-91 at 0.170") accommodate thicker PCB assemblies or provide additional solder joint strength. Standard post length (0.125") is suitable for typical single and double-sided boards.

Q: What is the current rating difference between the original and substitutes?

A: The 3M 100-008-050 is rated for 1 A, while all Mill-Max substitutes are rated for 3 A. The higher rating of substitutes provides additional design margin and does not create compatibility issues. Applications requiring only 1 A operation remain fully supported.

Q: Are there RoHS compliance considerations?

A: Mill-Max Series 110 and 111 parts with gold or tin finishes are ROHS3 compliant. Tin-lead variants (110-99, 110-93, 111-91, 111-93) are RoHS non-compliant. Design standards and procurement policies must be evaluated to determine compliance requirements.

Q: What is the difference between Series 110 and Series 111?

A: Series 110 and 111 are mechanically and electrically equivalent. Series 111 variants provide contact resistance specification (10 mOhm) where Series 110 does not. Both series are actively manufactured and suitable for new designs.

Q: Can the press-fit variant (104-13-308-41-770000) be used as a direct replacement?

A: The press-fit variant is mechanically compatible but requires different assembly equipment and processes. It is suitable only for applications where press-fit insertion capability exists. Solder-termination variants are recommended for standard wave or reflow soldering processes.
