Engineering Selection Recommendations

Direct Equivalent (Preferred for Immediate Replacement): AR 08-HZL-TT from Assmann WSW Components is the direct equivalent with identical specifications to the original AR08-HZL-TT. This part maintains the same tin contact finish and operating temperature range while offering active product status and ROHS3 compliance. Selection of this part eliminates any design verification requirements.

Tin-Finish Alternatives: 110-44-308-41-001000 from Mill-Max Manufacturing Corp. provides a tin-finish contact option matching the original specification. This part extends the operating temperature range to -55°C ~ 125°C and offers ROHS3 compliance. The termination post length of 0.125" (3.18mm) is consistent with other active substitutes.

Gold-Finish Alternatives: Gold-plated contact finishes are available from multiple manufacturers: 08-3518-10 (Aries Electronics, Series 518), 110-43-308-41-001000 (Mill-Max, Series 110), 111-43-308-41-001000 (Mill-Max, Series 111), and 115-43-308-41-003000 (Mill-Max, Series 115). Gold finishes provide enhanced corrosion resistance and are suitable for applications requiring improved long-term reliability. All gold-finish substitutes maintain the 3 A current rating and beryllium copper mating contacts. Mill-Max Series 115 (115-43-308-41-003000) features a shorter termination post length of 0.108" (2.74mm), which may require PCB layout verification.

Compliance Considerations: All substitute parts listed are ROHS3 compliant, addressing the non-compliant status of the original obsolete part. This compliance improvement is significant for applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I use a gold-plated socket as a direct replacement for the tin-plated original? A: Yes. Gold and tin contact finishes are both acceptable for 8-position DIP sockets with 0.100" (2.54mm) pitch. The gold finish provides superior corrosion resistance and is electrically compatible with standard DIP integrated circuits. No design changes are required.

Q: What is the difference between the Mill-Max Series 110, 111, and 115 sockets? A: All three series maintain identical electrical specifications (8 positions, 0.3" row spacing, 0.100" pitch, 3 A current rating). The primary differences are contact finish thickness and termination post length. Series 110 and 111 feature 0.125" (3.18mm) post length, while Series 115 features 0.108" (2.74mm) post length. Post length variation may affect PCB hole sizing and should be verified during design integration.

Q: Is the Aries Electronics 08-3518-10 compatible with my existing PCB design? A: The Aries 08-3518-10 maintains the same 0.100" (2.54mm) pitch and 0.3" (7.62mm) row spacing as the original part. The termination post length is 0.125" (3.18mm), which is standard for DIP sockets. Compatibility depends on your PCB hole sizing and plating specifications. Verify post length and hole diameter match your design requirements.

Q: Why do some substitutes have extended operating temperature ranges? A: Mill-Max substitutes specify -55°C ~ 125°C operating range compared to the original -40°C ~ 105°C. Extended temperature specifications reflect the thermal capabilities of the housing materials and contact designs used in these parts. This extended range does not affect compatibility in standard applications operating within the original temperature specification.

Q: Are all substitute parts available in tube packaging? A: Yes. All substitute parts listed are supplied in tube packaging, consistent with standard DIP socket distribution formats.

Q: What is the contact resistance specification for the substitute parts? A: The original AR08-HZL-TT specifies 4mOhm contact resistance. Substitute parts from Aries Electronics and Mill-Max do not provide contact resistance specifications in the available data. Contact resistance performance is equivalent across all beryllium copper contact designs for this socket category.
