DIP324-001BLF Equivalent & Substitute Parts

Part Overview

The DIP324-001BLF is a 24-position DIP socket manufactured by Amphenol ICC (FCI) designed for through-hole mounting of dual inline package integrated circuits. This connector features gold-plated beryllium copper mating contacts with 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch. 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 eligibility for DIP324-001BLF is determined by strict adherence to the following core parameters:

Position Count & Pitch: All substitutes must maintain 24 positions with 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) post pitch
Row Spacing: 0.3" (7.62mm) row spacing is mandatory
Mounting Configuration: Through-hole solder termination with 0.125" (3.18mm) post length
Contact Material: Beryllium copper mating contacts with brass or brass alloy posts
Mechanical Compatibility: Open frame design with polycyclohexylenedimethylene terephthalate (PCT) or thermoplastic housing

All identified substitutes meet these core electrical and mechanical requirements. Variations in contact finish (gold thickness, tin, or tin-lead), housing material composition, operating temperature range, current rating, and RoHS compliance status do not affect functional interchangeability for standard DIP socket applications.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with DIP324-001BLF for standard DIP socket applications. Selection among active alternatives should be based on the following criteria:

For RoHS3 Compliant Applications: Parts 110-13-324-41-001000, 110-87-324-41-001101, 110-11-324-41-001000, 110-41-324-41-001000, 110-43-324-41-001000, 110-44-324-41-001000, and 111-41-324-41-001000 meet ROHS3 compliance requirements.

For Non-Compliant Legacy Systems: Parts 110-91-324-41-001000, 110-93-324-41-001000, and 110-99-324-41-001000 are RoHS non-compliant and suitable for applications where lead-based finishes are acceptable.

For Highest Availability: Mill-Max Manufacturing Corp. series 110 and 111 parts offer the largest inventory quantities, with 110-44-324-41-001000 (2093 pcs), 110-13-324-41-001000 (2031 pcs), and 110-87-324-41-001101 (1900 pcs) providing immediate stock availability.

For Specific Contact Finish Requirements: Gold-plated mating contacts are available across most alternatives. Tin-plated mating contacts are offered in 110-44-324-41-001000. Tin-lead mating contacts are available in 110-99-324-41-001000.

For Extended Temperature Range: All active substitutes support -55°C to 125°C operating temperature, exceeding the unspecified range of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for DIP324-001BLF?

A: Yes. All listed substitutes maintain identical 24-position DIP configuration, 0.100" (2.54mm) pitch, 0.3" (7.62mm) row spacing, and through-hole solder termination. They are mechanically and electrically interchangeable for standard DIP socket applications.

Q: What is the difference between the various Mill-Max 110 series parts?

A: Mill-Max 110 series parts differ primarily in contact finish specifications. The numeric suffix (13, 11, 41, 43, 44, 91, 93, 99) designates different combinations of mating contact finish (gold, tin, or tin-lead) and post contact finish (gold, tin, or tin-lead). All maintain identical mechanical dimensions and electrical performance.

Q: Why does 111-41-324-41-001000 have a longer post length (0.170" vs 0.125")?

A: The 111-41-324-41-001000 features extended termination posts (0.170" / 4.32mm) compared to the standard 0.125" (3.18mm) length. This longer post length accommodates thicker PCB assemblies or applications requiring deeper solder penetration. Verify PCB thickness compatibility before selection.

Q: Are there RoHS compliance considerations for my application?

A: RoHS3 compliant alternatives include 110-13-324-41-001000, 110-87-324-41-001101, 110-11-324-41-001000, 110-41-324-41-001000, 110-43-324-41-001000, 110-44-324-41-001000, and 111-41-324-41-001000. Parts 110-91-324-41-001000, 110-93-324-41-001000, and 110-99-324-41-001000 are RoHS non-compliant due to tin-lead post finishes.

Q: What is the difference between Preci-Dip 110-87-324-41-001101 and Mill-Max alternatives?

A: Preci-Dip 110-87-324-41-001101 is the only non-Mill-Max substitute in the list. It features flash gold mating contact finish and tin post finish. All other mechanical and electrical parameters align with Mill-Max equivalents. Preci-Dip offers an alternative sourcing option with 1900 pcs inventory availability.

Q: Which substitute offers the best current rating?

A: Most active substitutes support 3 A current rating. The exception is Preci-Dip 110-87-324-41-001101, which is rated for 1 A. For applications requiring 3 A capacity, select any Mill-Max alternative or verify application current requirements against the 1 A rating.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All substitutes are mechanically and electrically compatible. However, for consistency in manufacturing and quality control, using a single part number across an assembly is recommended.
