Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 390262-2 is determined by the following critical parameters that must align with the original component specifications:

Primary Matching Criteria:

• Number of Positions: 28 (2 x 14) configuration
• Type: DIP socket with 0.6" (15.24mm) row spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole configuration
• Termination: Solder termination

Secondary Compatibility Parameters:

• Contact Finish - Mating: Tin or equivalent conductive finish
• Contact Material - Mating: Phosphor Bronze or equivalent
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Contact Resistance: 30mOhm or lower

The identified substitute parts meet these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring 28-position DIP socket connectors with standard 0.100" pitch spacing and through-hole solder termination.

Parameter Comparison

Engineering Selection Recommendations

Mill-Max Manufacturing 614-93-628-31-012000: This substitute provides active product status with extended operating temperature range (-55°C ~ 125°C) compared to the original 390262-2. The gold contact finish on mating surfaces offers enhanced corrosion resistance and contact reliability. However, this part maintains RoHS non-compliant status, matching the original component's regulatory classification. The beryllium copper contact material and gold plating represent an upgrade in contact performance characteristics. Current rating of 3A is specified for this part.

Assmann WSW Components A 28-LC-TT: This substitute achieves ROHS3 compliance, providing regulatory advantage over the original obsolete component. The tin contact finish and phosphor bronze contact material match the original 390262-2 specifications precisely. Operating temperature range of -55°C ~ 85°C encompasses the original specification's lower bound but does not extend to the original's 105°C maximum. Contact resistance of 30mOhm matches the original specification. Current rating of 1A is specified. This part is actively manufactured and available in high inventory quantities.

Both substitutes maintain the critical 28-position DIP configuration with 0.100" pitch spacing and through-hole solder termination required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the 614-93-628-31-012000 (Mill-Max) directly replace the 390262-2 in all applications?

A: The 614-93-628-31-012000 meets all primary electrical and mechanical parameters for functional replacement. The gold contact finish provides enhanced performance characteristics. However, the extended operating temperature range (-55°C ~ 125°C) versus the original (-40°C ~ 105°C) does not present a limitation. Verify that the application does not require RoHS compliance, as this part maintains non-compliant status matching the original.

Q: What are the key differences between the A 28-LC-TT and the original 390262-2?

A: The A 28-LC-TT maintains identical contact finish (tin) and contact material (phosphor bronze) specifications as the original. The primary differences are: (1) ROHS3 compliance status, (2) operating temperature maximum of 85°C versus the original 105°C, and (3) current rating of 1A versus unspecified for the original. The contact resistance of 30mOhm matches the original specification exactly.

Q: Does the operating temperature difference in the A 28-LC-TT affect substitution suitability?

A: The A 28-LC-TT operating temperature range of -55°C ~ 85°C does not encompass the original 390262-2 maximum of 105°C. Applications requiring operation above 85°C must use the 614-93-628-31-012000 (rated to 125°C) or verify that actual operating conditions remain within the A 28-LC-TT specification.

Q: Are there packaging differences between these parts?

A: The 390262-2 packaging is not specified in available data. The 614-93-628-31-012000 is supplied in tube packaging. The A 28-LC-TT is supplied in tube packaging. Both substitute parts feature open frame construction matching the original component.

Q: Which substitute part should be selected for new designs?

A: Selection depends on specific application requirements. For applications requiring RoHS3 compliance and operating below 85°C, the A 28-LC-TT is suitable. For applications requiring extended temperature operation to 125°C or enhanced contact performance through gold plating, the 614-93-628-31-012000 is appropriate. Both parts maintain the 28-position DIP socket configuration with 0.100" pitch spacing required for standard IC socket applications.

Q: What is the significance of the contact finish difference between tin and gold?

A: The tin contact finish on the 390262-2 and A 28-LC-TT provides standard electrical conductivity with contact resistance of 30mOhm. The gold contact finish on the 614-93-628-31-012000 provides enhanced corrosion resistance and improved contact reliability, particularly in environments with moisture or corrosive atmospheres. Both finishes are suitable for standard through-hole solder termination applications.
