Substitute Part Grouping Explanation

Substitution for the D2864-42 is determined by the following critical parameters: number of positions (64), row spacing (0.6"), mating pitch (0.100"), contact finish (gold), contact material (beryllium copper), mounting type (through hole), and operating temperature range (-55°C ~ 125°C).

The substitute parts are grouped into two categories:

Category 1: Direct Functional Equivalent (Same Row Spacing)

D2832-42: Harwin equivalent with reduced position count (32 positions) but identical row spacing and electrical characteristics. Suitable where pin count requirements differ.

Category 2: Electrical Equivalents with Different Row Spacing

110-83-964-41-001101, 110-87-964-41-001101: Preci-Dip 64-position sockets with 0.9" (22.86mm) row spacing. Electrically compatible but require PCB layout modification.
117-83-664-41-005101, 117-87-664-41-005101: Preci-Dip 64-position sockets with 0.6" (15.24mm) row spacing and 0.070" (1.78mm) pitch. Mechanically compatible with row spacing but different mating pitch.

Engineering Selection Recommendations

For Direct Replacement (No PCB Modification Required): D2832-42 is the preferred substitute when position count reduction is acceptable. It maintains identical row spacing (0.6"), mating pitch (0.100"), and all electrical specifications. Product status is active, ensuring long-term availability and ROHS3 compliance.

For 64-Position Requirement with Row Spacing Modification: 110-83-964-41-001101 and 110-87-964-41-001101 provide 64-position equivalence but require PCB layout adjustment due to 0.9" (22.86mm) row spacing versus the original 0.6" (15.24mm). Both are active products with ROHS3 compliance.

For 64-Position Requirement with Pitch Modification: 117-83-664-41-005101 and 117-87-664-41-005101 maintain 0.6" (15.24mm) row spacing but operate at 0.070" (1.78mm) mating pitch instead of 0.100" (2.54mm). These require IC package compatibility verification and PCB redesign. Both are active products with ROHS3 compliance.

All substitute parts meet the operating temperature range (-55°C ~ 125°C), current rating (1 A), and contact resistance (10mOhm) specifications of the original D2864-42.

Frequently Asked Questions (FAQ)

Q: Can D2832-42 be used as a direct replacement for D2864-42? A: D2832-42 is mechanically and electrically compatible for applications where 32 positions satisfy the design requirement. Row spacing and mating pitch are identical. Pin count is the only difference.

Q: What design changes are required when substituting with 110-83-964-41-001101 or 110-87-964-41-001101? A: PCB layout modification is required. The row spacing increases from 0.6" (15.24mm) to 0.9" (22.86mm), necessitating repositioning of socket mounting holes and trace routing adjustments.

Q: Are the Preci-Dip 117 series sockets compatible with standard 0.100" (2.54mm) pitch DIP packages? A: No. The 117 series operates at 0.070" (1.78mm) mating pitch. They are compatible only with IC packages designed for this pitch specification. PCB redesign and IC package verification are required.

Q: What is the significance of gold contact finish thickness differences? A: Contact finish thickness (Flash versus 29.5µin/0.75µm) affects contact durability and wear characteristics. Both specifications meet the electrical and reliability requirements for standard DIP socket applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (D2832-42, 110-83-964-41-001101, 110-87-964-41-001101, 117-83-664-41-005101, 117-87-664-41-005101) are ROHS3 compliant.

Q: Why is D2864-42 listed as obsolete? A: Harwin has discontinued the D2864-42. Active equivalent products from Harwin (D2832-42) and alternative manufacturers (Preci-Dip 110 and 117 series) are available for new designs and ongoing production support.
