Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-641615-2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 28 (2 x 14)
• Row Spacing: 0.6" (15.24mm)
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder

Secondary Compatibility Parameters:

• Operating Temperature Range
• Contact Finish Material (Gold vs. Tin)
• Contact Base Material (Beryllium Copper vs. Phosphor Bronze)
• Housing Material composition
• Contact Resistance specifications
• Flammability Rating (UL94 V-0)

Substitute parts are grouped into two categories:

Direct Equivalent: TE Connectivity 1-1825376-2 maintains identical electrical and mechanical specifications with the exception of frame design (Closed Frame vs. Open Frame). This part is fully interchangeable for applications where frame type does not impact circuit board layout or mechanical constraints.

Functional Alternatives: 3M 4828-6000-CP and Assmann WSW Components A 28-LC-TT provide equivalent 28-position DIP socket functionality with variations in contact finish material (Tin vs. Gold), contact base material (Phosphor Bronze vs. Beryllium Copper), and operating temperature ranges. These parts are suitable for applications where the specified parameter variations are acceptable within design requirements.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-1825376-2 (Direct Equivalent)

This part is the primary substitute for the 2-641615-2. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical specifications, operating temperature range (-55°C to 125°C), contact resistance (30mOhm), and gold-plated beryllium copper contacts. The only functional difference is the frame design (Closed Frame vs. Open Frame). Selection of this part is appropriate when the closed frame design is compatible with circuit board layout and mechanical assembly requirements. Product status is Active with 883 units in stock.

3M 4828-6000-CP (Functional Alternative)

This part provides equivalent 28-position DIP socket functionality with the following considerations: Contact finish is Tin rather than Gold, contact material is Phosphor Bronze rather than Beryllium Copper, and operating temperature range is limited to -25°C to 85°C. This part is suitable for applications where the reduced temperature range is acceptable and where tin-plated contacts meet corrosion and conductivity requirements. RoHS3 compliance is achieved. Product status is Active with 2209 units in stock.

Assmann WSW Components A 28-LC-TT (Functional Alternative)

This part provides equivalent 28-position DIP socket functionality with the following considerations: Contact finish is Tin rather than Gold, contact material is Phosphor Bronze rather than Beryllium Copper, and operating temperature range extends to -55°C but is limited to 85°C maximum. Housing material is polybutylene terephthalate (PBT) rather than thermoplastic glass-filled material. Contact resistance is specified at 30mOhm, matching the primary part. This part is suitable for applications where tin-plated contacts and the specified temperature range are acceptable. RoHS3 compliance is achieved. Product status is Active with 5518 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1825376-2 be used as a direct replacement for the 2-641615-2?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors and share identical electrical and mechanical specifications including 28-position configuration, 0.6" row spacing, 0.100" pitch, gold-plated beryllium copper contacts, and -55°C to 125°C operating temperature range. The difference in frame design (Closed vs. Open) does not affect electrical performance and is compatible with standard DIP socket applications unless specific circuit board layout constraints require the open frame design.

Q: What are the key differences between gold-plated and tin-plated contact finishes?

A: Gold plating provides superior corrosion resistance and lower contact resistance over extended service life. Tin plating offers adequate conductivity and corrosion resistance for most applications at lower cost. The 2-641615-2 uses gold plating (30.0µin thickness), while the 3M 4828-6000-CP and Assmann WSW A 28-LC-TT use tin plating (35.4µin and unspecified thickness respectively). Selection between these finishes depends on application environment and reliability requirements.

Q: Are there temperature range limitations when substituting parts?

A: Yes. The primary part (2-641615-2) and direct equivalent (1-1825376-2) operate from -55°C to 125°C. The 3M 4828-6000-CP is limited to -25°C to 85°C, which excludes it from applications requiring the full temperature range. The Assmann WSW A 28-LC-TT operates from -55°C to 85°C, providing lower temperature capability but reduced upper temperature limit. Verify application temperature requirements before selecting a substitute part.

Q: What is the significance of contact material differences (Beryllium Copper vs. Phosphor Bronze)?

A: Beryllium copper provides superior spring characteristics and contact force retention over extended insertion cycles. Phosphor bronze offers adequate performance for standard applications at lower cost. The primary part uses beryllium copper, while the 3M and Assmann WSW alternatives use phosphor bronze. This difference affects long-term reliability in high-cycle insertion applications but is acceptable for fixed-installation socket applications.

Q: Do the substitute parts meet RoHS compliance requirements?

A: The primary part (2-641615-2) is RoHS non-compliant. The TE Connectivity 1-1825376-2 has RoHS status listed as "Not applicable." The 3M 4828-6000-CP and Assmann WSW A 28-LC-TT are both ROHS3 compliant. If RoHS compliance is a design requirement, the 3M or Assmann WSW parts are appropriate selections.

Q: What packaging formats are available for these parts?

A: The primary part (2-641615-2) and direct equivalent (1-1825376-2) are supplied without specified packaging designation. The 3M 4828-6000-CP is supplied in Tube packaging. The Assmann WSW A 28-LC-TT is supplied in Tube packaging. Verify packaging requirements for automated assembly or bulk handling applications.

Q: Are all substitute parts rated for the same current capacity?

A: The primary part (2-641615-2) does not specify a current rating. The TE Connectivity 1-1825376-2 does not specify a current rating. The 3M 4828-6000-CP is rated for 1 Ampere. The Assmann WSW A 28-LC-TT is rated for 1 Ampere. For applications requiring current rating specifications, the 3M and Assmann WSW parts provide explicit 1 Ampere ratings.

Q: What is the difference between Open Frame and Closed Frame socket designs?

A: Open Frame design (2-641615-2, 4828-6000-CP, A 28-LC-TT) provides unrestricted access to socket contacts and is suitable for standard DIP package insertion. Closed Frame design (1-1825376-2) provides additional mechanical support and contact protection. Both designs are functionally equivalent for standard DIP socket applications. Selection depends on circuit board layout and mechanical assembly requirements.
