DIP328-014BLF Equivalent & Substitute Parts

Part Overview

The DIP328-014BLF is a 28-position DIP socket manufactured by Amphenol ICC (FCI), designed for through-hole mounting of dual inline package integrated circuits. This component features a 0.3" (7.62mm) row spacing with tin contact finish on mating surfaces and brass posts. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the DIP328-014BLF is determined by strict adherence to the following electrical and mechanical parameters:

28-position configuration with 2 x 14 arrangement
0.3" (7.62mm) row spacing
0.100" (2.54mm) pitch on both mating and post sides
Through-hole solder termination
Beryllium copper mating contacts
Brass or brass alloy post contacts
UL94 V-0 flammability rating
Unlimited moisture sensitivity level (MSL 1)

All substitute parts listed maintain these core parameters. Variations in contact finish (gold versus tin), contact finish thickness, termination post length, and post finish material (tin versus tin-lead) are permitted within the scope of electrical and mechanical compatibility. Substitute parts from Mill-Max Manufacturing Corp. (612 series) and Harwin Inc. (D2 series) meet these criteria and are classified as active products.

Engineering Selection Recommendations

All Mill-Max 612 series substitutes (612-41-328-41-003000, 612-43-328-41-003000, 612-43-328-41-004000, 612-91-328-41-003000, 612-93-328-41-003000, 612-93-328-41-004000) are classified as active products with ROHS3 compliance. These parts maintain full electrical and mechanical compatibility with the DIP328-014BLF while offering improved contact finish (gold) and documented operating temperature ranges of -55°C to 125°C.

The Harwin D2928-42 is an active alternative with gold contact finish and documented operating temperature range. However, this part carries RoHS non-compliant status and a lower current rating of 1 A compared to the 3 A rating of Mill-Max alternatives.

For new designs and production applications requiring RoHS compliance, Mill-Max 612 series sockets are the preferred substitutes. Selection among Mill-Max variants depends on termination post length requirements: 0.183" (4.65mm) for standard applications (612-41, 612-43, 612-91, 612-93 with -003000 suffix) or 0.273" (6.93mm) for extended post length applications (612-43, 612-93 with -004000 suffix). Contact finish thickness and post finish material variations (tin versus tin-lead) do not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DIP328-014BLF be directly replaced with any of the listed substitutes?

A: Yes. All listed substitutes maintain the critical electrical and mechanical parameters: 28-position configuration, 0.3" row spacing, 0.100" pitch, through-hole solder termination, beryllium copper mating contacts, and UL94 V-0 flammability rating. Variations in contact finish, post length, and post material do not affect functional compatibility.

Q: What is the difference between the Mill-Max 612-41, 612-43, 612-91, and 612-93 series?

A: These variants differ in contact finish thickness and post finish material. The 612-41 and 612-91 feature 10.0µin (0.25µm) gold on mating contacts, while 612-43 and 612-93 feature 30.0µin (0.76µm) gold. Post finish is tin for 612-41 and 612-43, and tin-lead for 612-91 and 612-93. All maintain 10mOhm contact resistance and 3 A current rating.

Q: Does termination post length affect compatibility?

A: Termination post length affects PCB design and assembly considerations but does not affect electrical compatibility. The DIP328-014BLF has 0.125" (3.18mm) posts. Mill-Max alternatives offer 0.183" (4.65mm) or 0.273" (6.93mm) options. The Harwin D2928-42 provides 0.126" (3.20mm) posts, closely matching the original specification.

Q: Why do some substitutes have higher current ratings than the original part?

A: The original DIP328-014BLF does not specify a current rating. Mill-Max substitutes are rated at 3 A, and the Harwin alternative at 1 A. These ratings reflect manufacturer testing and documentation. The higher ratings of Mill-Max parts indicate enhanced electrical performance capability.

Q: Is RoHS compliance a critical factor for substitution?

A: RoHS compliance status depends on application requirements and regulatory jurisdiction. All Mill-Max 612 series substitutes are ROHS3 compliant, meeting current European Union and similar regulatory standards. The Harwin D2928-42 is RoHS non-compliant and should be selected only when legacy compliance status is acceptable.

Q: Can I mix different Mill-Max variants in the same design?

A: Yes. All Mill-Max 612 series variants are electrically and mechanically compatible. Mixing variants with different post lengths or post finishes is acceptable provided PCB design accommodates the post length variation and soldering processes are compatible with the post finish material.
