Equivalent & Substitute Parts for D2628-42

Part Overview

The D2628-42 is a 28-position DIP socket manufactured by Harwin Inc., designed for IC and transistor applications with 0.6" (15.24mm) row spacing. This component features gold-plated mating contacts, press-fit termination, and through-hole mounting. The D2628-42 is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning. The D2828-42 serves as the manufacturer-recommended equivalent, offering functional compatibility with updated specifications and active product status.

Substitute Part Grouping Explanation

The D2828-42 qualifies as a direct substitute for the D2628-42 based on the following critical parameters:

• Position Count & Spacing: Both components provide 28 positions in a 2 x 14 configuration with identical 0.6" (15.24mm) row spacing and 0.100" (2.54mm) mating pitch
• Electrical Characteristics: Matching gold-plated beryllium copper mating contacts, 1 A current rating, and 10mOhm contact resistance
• Thermal Performance: Identical operating temperature range of -55°C ~ 125°C
• Compliance: Both components maintain ROHS3 compliance and UL94 V-0 flammability rating
• Mounting Interface: Through-hole mounting with compatible post specifications

The primary differences between these components are termination method (press-fit versus solder), post length (0.110" versus 0.126"), and housing material (PCT polyester glass-filled versus plastic), which do not affect functional compatibility in standard DIP socket applications.

Engineering Selection Recommendations

The D2828-42 is the manufacturer-recommended substitute for the obsolete D2628-42. Selection of the D2828-42 is supported by:

• Active Product Status: The D2828-42 maintains active product status with established supply chain availability (1260 pcs in stock), whereas the D2628-42 is obsolete
• Regulatory Compliance: Both components maintain identical ROHS3 compliance and UL94 V-0 flammability certification, ensuring continued compliance with applicable standards
• Functional Equivalence: Electrical and thermal specifications are identical across all critical parameters, including contact resistance, current rating, and operating temperature range
• Mechanical Compatibility: Identical position count, row spacing, and mating pitch ensure direct mechanical fit in existing PCB designs

The transition from press-fit to solder termination and the minor post length variation (0.016" difference) represent design improvements in the active substitute and do not compromise functional performance in standard DIP socket applications.

Frequently Asked Questions (FAQ)

Q: Can the D2828-42 directly replace the D2628-42 in existing designs?

A: Yes. Both components share identical position count (28), row spacing (0.6"), mating pitch (0.100"), contact materials, and electrical ratings. The primary difference is termination method: the D2628-42 uses press-fit termination while the D2828-42 uses solder termination. PCB design modifications may be required to accommodate the solder termination method.

Q: What is the significance of the termination method difference?

A: The D2628-42 employs press-fit termination, which requires mechanical insertion into plated through-holes. The D2828-42 uses solder termination, which requires standard PCB soldering processes. This difference affects assembly methodology but does not impact electrical or thermal performance.

Q: Are there any compliance or certification differences between these components?

A: No. Both the D2628-42 and D2828-42 maintain identical ROHS3 compliance status and UL94 V-0 flammability rating. No additional compliance considerations apply to the substitution.

Q: Does the post length difference affect compatibility?

A: The D2828-42 post length is 0.126" compared to 0.110" for the D2628-42, a difference of 0.016". This variation is accommodated within standard PCB through-hole depth tolerances and does not affect functional compatibility.

Q: Why is the D2628-42 classified as obsolete?

A: The D2628-42 has been superseded by the D2828-42 in the manufacturer's active product line. The D2828-42 offers improved supply chain availability and active product support while maintaining functional equivalence.
