DIP328-011BLF Equivalent & Substitute Parts

Part Overview

The DIP328-011BLF is a 28-position DIP socket manufactured by Amphenol ICC (FCI) designed for IC and transistor applications with 0.3" (7.62mm) row spacing. This component features gold-plated beryllium copper mating contacts and tin-plated brass posts for through-hole soldering. The part is currently obsolete, making equivalent substitutes from active manufacturers necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the DIP328-011BLF is determined by strict equivalence across the following critical parameters:

Position Count & Row Spacing: All substitutes maintain 28 positions in 2 x 14 configuration with 0.3" (7.62mm) row spacing
Pitch Specifications: Mating and post pitch remain 0.100" (2.54mm) across all alternatives
Contact Materials: Mating contacts are beryllium copper with gold finish; post contacts are brass or brass alloy with tin or tin-lead finish
Mounting & Termination: All substitutes are through-hole solder termination with open frame carrier design
Electrical Performance: Current rating of 3 A and contact resistance of 10mOhm are consistent across active substitutes
Environmental Compliance: All substitutes maintain UL94 V-0 flammability rating and MSL 1 classification

The primary differentiators among substitutes are termination post length (0.183" or 0.273"), contact finish thickness on mating surfaces (10.0µin or 30.0µin), and post finish composition (tin versus tin-lead). These variations allow selection based on specific PCB design requirements and RoHS compliance needs.

Engineering Selection Recommendations

All Mill-Max 612 series substitutes are active products with ROHS3 compliance, providing long-term availability advantages over the obsolete DIP328-011BLF. Selection among the six available substitutes depends on specific PCB design requirements:

For standard applications with 0.183" post length: Choose 612-41-328-41-003000 (tin post finish, 10.0µin gold mating finish), 612-43-328-41-003000 (tin post finish, 30.0µin gold mating finish), 612-91-328-41-003000 (tin-lead post finish, 10.0µin gold mating finish), or 612-93-328-41-003000 (tin-lead post finish, 30.0µin gold mating finish).

For applications requiring extended post length (0.273"): Choose 612-43-328-41-004000 (tin post finish) or 612-93-328-41-004000 (tin-lead post finish).

For RoHS-compliant designs: All Mill-Max substitutes meet ROHS3 requirements. Tin-finished post options (612-41 and 612-43 series) are preferred for lead-free soldering environments. Tin-lead finished options (612-91 and 612-93 series) are suitable for legacy applications.

For enhanced contact durability: The 30.0µin gold mating finish (612-43 and 612-93 series) provides thicker plating compared to the 10.0µin specification of the original part and 612-41/612-91 alternatives.

Frequently Asked Questions (FAQ)

Q: Can I directly replace DIP328-011BLF with any of the Mill-Max substitutes?

A: Yes, all six Mill-Max 612 series parts are electrically and mechanically equivalent. The primary consideration is termination post length. The original DIP328-011BLF has 0.125" posts, while Mill-Max substitutes have either 0.183" or 0.273" posts. Verify your PCB design accommodates the longer post length before selection.

Q: What is the difference between tin and tin-lead post finishes?

A: Tin-finished posts (612-41 and 612-43 series) are lead-free and suitable for RoHS-compliant manufacturing. Tin-lead finished posts (612-91 and 612-93 series) are for legacy applications where lead-based solder is acceptable. Both finishes are compatible with standard through-hole soldering processes.

Q: Why do some substitutes have thicker gold plating on mating contacts?

A: The 30.0µin gold finish (612-43 and 612-93 series) provides extended contact life and improved wear resistance compared to the 10.0µin specification. This is beneficial for applications with frequent insertion and removal cycles or high-reliability requirements.

Q: Are all substitutes available in the same packaging?

A: All Mill-Max substitutes are supplied in tube packaging. The original DIP328-011BLF packaging is not specified in the provided data.

Q: What is the inventory status for these substitutes?

A: All Mill-Max 612 series substitutes are in active production with current stock availability ranging from 720 to 1109 pieces. The original DIP328-011BLF has 995 pieces in stock but is obsolete.

Q: Do the substitutes maintain the same electrical performance?

A: Yes. All substitutes maintain 3 A current rating, 10mOhm contact resistance, and -55°C to 125°C operating temperature range. The original part specifications for these parameters were not provided but are consistent with industry standards for this socket category.
