Engineering Selection Recommendations

ICO-640-NGT (Samtec Inc.) is the primary selection for applications requiring ROHS3 compliance. This part maintains Active product status with established supply availability (970 units in stock) and meets stringent environmental regulations applicable to consumer electronics and regulated industries.

115-93-640-41-003000 (Mill-Max Manufacturing Corp.) serves as a functional equivalent for applications where RoHS compliance is not mandated. This substitute provides higher current rating capacity (3 A versus 1 A) and maintains identical mechanical and electrical mating characteristics. The part is Active and available (668 units in stock). Selection of this substitute requires confirmation that RoHS non-compliance aligns with end-application requirements and regulatory environment.

Both parts share identical critical parameters: 40-position DIP configuration, 0.6" row spacing, 0.100" pitch, gold-plated beryllium copper mating contacts, through-hole mounting, and -55°C to 125°C operating temperature range. Substitution between these parts is mechanically and electrically valid based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can 115-93-640-41-003000 directly replace ICO-640-NGT in existing PCB designs?

A: Yes. Both parts share identical mechanical footprints (40-position DIP, 0.6" row spacing, 0.100" pitch) and electrical mating characteristics (gold-plated beryllium copper contacts). Direct PCB-level substitution is supported without layout modifications.

Q: What is the primary difference between these two socket types?

A: The primary difference is RoHS compliance status. ICO-640-NGT is ROHS3 compliant; 115-93-640-41-003000 is RoHS non-compliant. Additionally, 115-93-640-41-003000 provides higher current rating (3 A versus 1 A) and uses tin-lead post finish versus tin-only finish on the main part.

Q: Are the contact materials identical?

A: Mating contacts are identical on both parts: beryllium copper with 30.0µin gold plating. Post materials differ slightly: ICO-640-NGT uses brass with tin finish; 115-93-640-41-003000 uses brass alloy with tin-lead finish.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts operate from -55°C to 125°C, supporting equivalent thermal performance in industrial and commercial applications.

Q: Which part should be selected for consumer electronics applications?

A: ICO-640-NGT is the appropriate selection for consumer electronics requiring RoHS3 compliance. Regulatory requirements in target markets determine compliance necessity.
