Engineering Selection Recommendations
Tier 1 - Direct Equivalents (Recommended for New Designs):
The Assmann WSW Components A 40-LC-TR and A 40-LC-TT represent the closest functional equivalents to the 4-382568-0. Both parts maintain identical pin configuration, pitch, row spacing, and contact specifications. The A 40-LC-TR and A 40-LC-TT are active products with ROHS3 compliance and UL94 V-0 flammability ratings. The primary difference between these Assmann parts is frame design (open frame) compared to the original closed frame, which does not affect electrical or mechanical compatibility for standard DIP socket applications. Operating temperature range of -55°C to 85°C covers the majority of industrial applications, though applications requiring operation above 85°C require alternative selection.
Tier 2 - Functional Equivalents (3M Series 4800):
The 3M 4840-6000-CP and 4840-6004-CP sockets provide identical 40-position DIP configuration with tin contact finish and phosphor bronze materials. These parts are active products with ROHS3 compliance and UL94 V-0 rating. The 3M parts feature open frame design and are suitable for applications with operating temperature requirements between -25°C and 85°C. Current rating of 1 Amp is specified for 3M parts, matching the Assmann alternatives.
Tier 3 - Enhanced Performance Alternative (Mill-Max 116-93-640-41-006000):
The Mill-Max 116-93-640-41-006000 offers enhanced performance characteristics including gold contact finish, beryllium copper contact material, and extended operating temperature range of -55°C to 125°C. This part is active and REACH compliant. However, this part is RoHS non-compliant and does not specify flammability rating, limiting its use in applications with strict compliance requirements. The gold finish and beryllium copper contacts provide superior contact reliability and lower contact resistance (10mOhm versus 30mOhm) for high-reliability applications.
Compliance Considerations:
For applications requiring ROHS3 compliance and UL94 V-0 flammability certification, the Assmann WSW A 40-LC-TR or A 40-LC-TT are the appropriate selections. The 3M 4840-6000-CP and 4840-6004-CP also meet these requirements. The Mill-Max 116-93-640-41-006000 is not suitable for RoHS-compliant applications.
Frequently Asked Questions (FAQ)
Q: Can the A 40-LC-TR directly replace the obsolete 4-382568-0 in existing designs?
A: Yes. The A 40-LC-TR maintains all critical electrical and mechanical parameters: 40-position DIP configuration, 0.6" row spacing, 0.100" pitch, tin contact finish, phosphor bronze contacts, through-hole solder termination, and identical contact resistance of 30mOhm. The open frame design does not affect functional compatibility. The operating temperature range of -55°C to 85°C is suitable for most applications; designs requiring operation above 85°C require alternative selection.
Q: What is the difference between the Assmann A 40-LC-TT and A 40-LC-TR?
A: Both parts are functionally identical 40-position DIP sockets with tin finish and phosphor bronze contacts. The primary difference is packaging: A 40-LC-TT is supplied in tube packaging, while A 40-LC-TR is also supplied in tube packaging. Both are active products with identical electrical specifications and ROHS3 compliance.
Q: Why does the Mill-Max 116-93-640-41-006000 have lower contact resistance?
A: The Mill-Max part uses beryllium copper contact material and gold finish on the mating contacts, which provide superior electrical conductivity compared to phosphor bronze with tin finish. Contact resistance of 10mOhm versus 30mOhm reflects this material difference. However, for standard DIP socket applications, both contact resistance values are acceptable.
Q: Are the 3M 4840-6000-CP and 4840-6004-CP interchangeable?
A: Yes. Both 3M parts are functionally identical 40-position DIP sockets with tin finish, phosphor bronze contacts, and identical electrical specifications. Both are active products with ROHS3 compliance and UL94 V-0 rating.
Q: What is the significance of the closed frame versus open frame design?
A: The original 4-382568-0 features a closed frame design, while most substitute parts feature open frame design. Frame design does not affect electrical performance or mechanical compatibility for standard DIP integrated circuits. Open frame design may provide slightly improved thermal dissipation in high-power applications.
Q: Can I use the Mill-Max 116-93-640-41-006000 in a RoHS-compliant application?
A: No. The Mill-Max 116-93-640-41-006000 is RoHS non-compliant. For applications requiring RoHS3 compliance, select the Assmann A 40-LC-TR, A 40-LC-TT, or 3M 4840-6000-CP / 4840-6004-CP.
Q: Which substitute part is recommended for high-temperature applications above 85°C?
A: The Mill-Max 116-93-640-41-006000 supports operating temperatures up to 125°C. However, this part is RoHS non-compliant. For applications requiring both high-temperature operation and RoHS compliance, design review is necessary as no substitute part meets both criteria.
Q: What is the current rating for each substitute part?
A: The Assmann A 40-LC-TR and A 40-LC-TT are rated for 1 Amp. The 3M 4840-6000-CP and 4840-6004-CP are rated for 1 Amp. The Mill-Max 116-93-640-41-006000 is rated for 3 Amps, providing higher current capacity for applications requiring increased current handling.
