Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): The 4848-6004-CP represents the optimal direct substitute, maintaining identical mechanical and electrical characteristics while offering active product status and ROHS3 compliance. This part is recommended for applications where the original operating temperature range (-65°C ~ 105°C) and 1 A current rating are required.

For Enhanced Performance Applications: The Mill-Max 116-series parts (116-41-648-41-006000, 116-91-648-41-006000, and 116-93-648-41-006000) provide superior performance characteristics including extended operating temperature range (-55°C ~ 125°C), increased current rating (3 A), and gold-plated mating contacts for improved contact reliability. These parts are suitable for applications requiring higher performance margins or enhanced environmental specifications.

Compliance Considerations: The 4848-6004-CP and Mill-Max 116-41-648-41-006000 both carry ROHS3 compliance certification, making them suitable for applications subject to RoHS regulations. The original ICO-486-S8A-T is RoHS non-compliant; substitution with compliant alternatives is necessary for regulated applications.

Temperature Range Limitations: Applications requiring the full -65°C lower temperature limit of the original part should note that the 4848-6004-CP operates only to -25°C minimum. The Mill-Max 116-series parts extend to -55°C, providing closer alignment to the original specification while not achieving the full -65°C lower limit.

Frequently Asked Questions (FAQ)

Q: Can the 4848-6004-CP be used as a direct replacement for the ICO-486-S8A-T? A: Yes. The 4848-6004-CP maintains identical pin count (48), row spacing (0.6"), pitch (0.100"), contact finish (tin), and current rating (1 A). The primary difference is the reduced operating temperature range (-25°C ~ 85°C versus -65°C ~ 105°C). Verify that your application does not require operation below -25°C.

Q: What are the advantages of the Mill-Max 116-series substitutes? A: The 116-series parts offer three key advantages: extended operating temperature range (-55°C ~ 125°C), increased current rating (3 A), and gold-plated mating contacts for superior contact reliability. These enhancements provide greater performance margins for demanding applications.

Q: Are there any mechanical differences between the substitute parts? A: All substitute parts maintain the same 48-position DIP configuration and 0.6" row spacing. The Mill-Max 116-series parts feature an elevated frame design and vary in termination post length. The 116-93-648-41-006000 has a shorter post length (0.108") compared to the 116-41 and 116-91 variants (0.236"). Verify PCB hole depth compatibility before selection.

Q: Which substitute is recommended for new designs? A: For new designs, the 4848-6004-CP is recommended if the original operating temperature and current specifications are sufficient. For applications requiring enhanced performance or extended temperature range, the Mill-Max 116-41-648-41-006000 is the preferred choice due to its ROHS3 compliance and superior electrical characteristics.

Q: Do all substitutes have the same contact finish? A: No. The 4848-6004-CP maintains tin-plated contacts matching the original. The Mill-Max 116-series parts feature gold-plated mating contacts with tin or tin-lead plated posts. Gold plating provides improved corrosion resistance and contact reliability compared to tin plating.

Q: What is the packaging difference between these parts? A: The ICO-486-S8A-T packaging is not specified in the data. The 4848-6004-CP is supplied in tube packaging. The Mill-Max 116-series parts are also supplied in tube packaging. Confirm packaging requirements with your procurement specifications.
