D2806-42 Equivalent & Substitute Parts

Part Overview

The D2806-42 is a 6-position DIP socket manufactured by Harwin Inc., designed for IC and transistor applications with 0.3" (7.62mm) row spacing. This through-hole component features gold-plated mating contacts and tin-plated posts, operating across the industrial temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent parts are identified when they maintain identical electrical and mechanical specifications, enabling direct substitution in circuit designs where socket compatibility is critical.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 110-87-306-41-001101 (Preci-Dip) qualifies as an equivalent based on the following critical parameters:

• Position Configuration: Both parts provide 6 positions in a 2 x 3 arrangement
• Row Spacing: Both maintain 0.3" (7.62mm) row spacing for DIP compatibility
• Pitch Specifications: Mating and post pitch both standardized at 0.100" (2.54mm)
• Contact Materials: Beryllium copper mating contacts and brass posts in both parts
• Contact Finish: Gold-plated mating surface (flash thickness) with tin-plated posts
• Mounting Method: Through-hole termination with solder connection
• Electrical Performance: Identical 1 A current rating and 10mOhm contact resistance
• Environmental Compliance: Both rated UL94 V-0, ROHS3 compliant, and MSL 1
• Operating Range: Identical -55°C to 125°C temperature specification

Minor variations in housing material (Harwin uses plastic; Preci-Dip uses PCT polyester with glass fill) and termination post length (3.20mm vs 3.18mm) do not affect functional substitution for standard DIP socket applications.

Parameter Comparison

Engineering Selection Recommendations

Both the D2806-42 and 110-87-306-41-001101 are active production parts with identical compliance certifications. Selection between these parts should be based on:

• Availability: Preci-Dip 110-87-306-41-001101 shows higher inventory (9595 pcs vs 950 pcs)
• Packaging: Preci-Dip supplies in tube packaging; Harwin packaging not specified
• Housing Material: Preci-Dip uses glass-filled PCT polyester, offering enhanced mechanical stability compared to standard plastic
• Post Length Tolerance: Harwin specifies 0.126" (3.20mm); Preci-Dip specifies 0.125" (3.18mm) — both acceptable for standard PCB through-hole applications with 0.100" (2.54mm) pitch

Both parts meet all regulatory requirements (ROHS3, REACH unaffected, EAR99 classification) and maintain identical electrical performance across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 110-87-306-41-001101 directly replace the Harwin D2806-42 on existing PCBs?

A: Yes. Both parts maintain identical pitch specifications (0.100" mating and post), 6-position 2x3 configuration, and 0.3" row spacing. The minor post length difference (3.20mm vs 3.18mm) is within standard PCB tolerance for through-hole mounting.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts specify 1 A current rating, 10mOhm contact resistance, and identical contact materials (beryllium copper mating, brass posts). Gold flash plating on mating contacts and tin plating on posts are equivalent in both parts.

Q: What is the significance of the housing material difference?

A: Harwin uses plastic housing; Preci-Dip uses glass-filled PCT polyester. The glass-filled material in the Preci-Dip part provides enhanced mechanical rigidity and thermal stability, though both materials meet UL94 V-0 flammability requirements.

Q: Do both parts support the same temperature range?

A: Yes. Both parts operate across -55°C to 125°C, suitable for industrial and commercial applications.

Q: Are there packaging considerations for board assembly?

A: Preci-Dip supplies the 110-87-306-41-001101 in tube packaging. Confirm packaging compatibility with your assembly process requirements.

Q: Do both parts comply with current environmental regulations?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.
