D0808-01 Equivalent & Substitute Parts

Part Overview

The D0808-01 is an 8-position DIP socket manufactured by Harwin Inc., designed for through-hole mounting applications with gold-plated mating contacts and wire wrap termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The socket accommodates 8-pin DIP packages with 0.3" row spacing and 0.100" pitch, operating across the -55°C to 125°C temperature range.

Substitute Part Grouping Explanation

Substitution for the D0808-01 is determined by strict equivalence across the following critical parameters:

Pin Configuration: 8 positions in 2 x 4 arrangement
Pitch Specifications: 0.100" (2.54mm) mating and post pitch
Row Spacing: 0.3" (7.62mm)
Contact System: Gold-plated beryllium copper mating contacts with tin-plated brass posts
Mounting Method: Through-hole wire wrap termination
Electrical Performance: 1 A current rating and 10mOhm contact resistance
Environmental Rating: UL94 V-0 flammability classification and -55°C to 125°C operating range

Two substitute parts meet these criteria: D0808-42 (Harwin Inc., active status) and 122-87-308-41-001101 (Preci-Dip, active status). Both maintain functional and electrical equivalence to the D0808-01 within the specified parameter set.

Engineering Selection Recommendations

D0808-42 (Harwin Inc.) is the primary substitute for the D0808-01. Both parts share identical manufacturer lineage within the D0 series, with D0808-42 maintaining active product status and ROHS3 compliance. The D0808-42 provides direct functional equivalence with matching termination post length (0.510"), making it suitable for direct replacement in existing PCB designs without layout modifications.

122-87-308-41-001101 (Preci-Dip) serves as an alternative substitute with full electrical and mechanical compatibility. This part achieves ROHS3 compliance and maintains all critical electrical parameters. The termination post length differs at 0.370" (9.40mm) compared to the D0808-01 specification of 0.510" (12.95mm), requiring verification of PCB hole depth and wire wrap clearance during integration.

Both substitute parts are classified as active products with current manufacturing availability, addressing the obsolescence status of the D0808-01.

Frequently Asked Questions (FAQ)

Q: Can D0808-42 be used as a direct replacement for D0808-01 in existing designs?

A: Yes. The D0808-42 maintains identical pin configuration, pitch specifications, contact materials, and termination post length. No PCB layout modifications are required.

Q: What is the significance of the termination post length difference in the Preci-Dip substitute?

A: The 122-87-308-41-001101 features a 0.370" post length versus the 0.510" specification of the D0808-01. This affects wire wrap depth and PCB hole engagement. Verify that your PCB design accommodates the shorter post length before selection.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both D0808-42 and 122-87-308-41-001101 are ROHS3 compliant, whereas the D0808-01 is RoHS non-compliant. This compliance improvement supports modern procurement and environmental requirements.

Q: Do the substitute parts maintain the same electrical performance?

A: Yes. Both substitutes maintain 1 A current rating, 10mOhm contact resistance, and -55°C to 125°C operating temperature range. Contact finish materials and mating contact specifications are equivalent.

Q: What is the difference between the gold plating specifications?

A: The D0808-01 and D0808-42 specify 10.0µin (0.25µm) gold plating thickness on mating contacts. The 122-87-308-41-001101 specifies flash gold plating, which provides thinner coverage. Both meet functional requirements for the 1 A current rating and contact resistance specification.

Q: Which substitute should be selected for new designs?

A: Selection depends on PCB design constraints. For designs matching the original 0.510" post length specification, D0808-42 is recommended. For designs with shorter post length requirements, 122-87-308-41-001101 is suitable. Both parts support current manufacturing and compliance requirements.
