The identified substitute parts 4828-6000-CP (3M) and A 28-LC-TT (Assmann WSW Components) maintain all fixed parameters while offering alternative contact finishes and housing materials suitable for equivalent IC and transistor socket applications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1825375-2 (Primary Part)

The TE Connectivity 1825375-2 is the original specification part with active product status. It features gold contact finish with 15.0µin thickness, a closed frame design, and operates across an extended temperature range of -55°C to 125°C. This part is RoHS Compliant and carries a contact resistance specification of 30mOhm. The gold plating provides superior corrosion resistance and is preferred for applications requiring long-term reliability and minimal contact degradation.

3M 4828-6000-CP (Substitute Option)

The 3M 4828-6000-CP is an active product with ROHS3 Compliance status. It features tin contact finish with 35.4µin thickness and an open frame design. The operating temperature range is -25°C to 85°C, which is narrower than the primary part. This substitute is suitable for applications operating within the specified temperature limits where tin plating is acceptable. The higher contact finish thickness provides additional durability in the tin coating.

Assmann WSW A 28-LC-TT (Substitute Option)

The Assmann WSW A 28-LC-TT is an active product with ROHS3 Compliance status. It features tin contact finish with an open frame design and operates across -55°C to 85°C. This part maintains the same lower temperature limit as the primary part and includes a specified contact resistance of 30mOhm. The PBT housing material provides alternative mechanical properties compared to the thermoplastic glass-filled housing of the primary part. This substitute is suitable for applications requiring tin plating and extended low-temperature operation.

Selection Criteria:

• Select the TE Connectivity 1825375-2 for applications requiring gold plating, extended temperature range (-55°C to 125°C), or closed frame design.
• Select the 3M 4828-6000-CP for applications within -25°C to 85°C operating range where tin plating is acceptable and open frame design is compatible.
• Select the Assmann WSW A 28-LC-TT for applications requiring tin plating, extended low-temperature operation (-55°C), and open frame design with PBT housing.

All three parts maintain identical mechanical compatibility with 28-position DIP packages using 0.100" (2.54mm) pitch and 0.6" (15.24mm) row spacing.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4828-6000-CP be used as a direct replacement for the TE Connectivity 1825375-2?

A: The 3M 4828-6000-CP is mechanically compatible with the TE Connectivity 1825375-2 for 28-position DIP socket applications. However, the operating temperature range differs (-25°C to 85°C versus -55°C to 125°C), and the contact finish is tin instead of gold. Substitution is valid only if the application operates within the 3M part's temperature limits and tin plating is acceptable for the intended use.

Q: What is the difference between gold and tin contact finishes in DIP sockets?

A: Gold plating provides superior corrosion resistance, lower contact resistance degradation over time, and is preferred for long-term reliability applications. Tin plating is cost-effective and suitable for applications with shorter service life or less demanding environmental conditions. Both finishes are electrically functional; the choice depends on application requirements and cost considerations.

Q: Are the open frame and closed frame designs interchangeable?

A: Open frame and closed frame designs are mechanically interchangeable for standard DIP socket applications. The frame type affects mechanical support and dust protection but does not impact electrical performance. Selection depends on PCB layout requirements and environmental protection needs.

Q: What does the contact finish thickness specification mean?

A: Contact finish thickness indicates the plating layer depth. The TE Connectivity 1825375-2 has 15.0µin (0.38µm) gold plating, while the 3M 4828-6000-CP has 35.4µin (0.90µm) tin plating. Thicker plating generally provides longer service life and better corrosion resistance, though both thicknesses are within industry standards for DIP sockets.

Q: Can I use the Assmann WSW A 28-LC-TT in applications requiring the full -55°C to 125°C temperature range?

A: The Assmann WSW A 28-LC-TT operates from -55°C to 85°C, which does not cover the upper temperature limit of 125°C specified for the TE Connectivity 1825375-2. This substitute is not suitable for applications requiring operation above 85°C.

Q: Are all three parts RoHS compliant?

A: The TE Connectivity 1825375-2 is RoHS Compliant. The 3M 4828-6000-CP and Assmann WSW A 28-LC-TT are both ROHS3 Compliant. All three parts meet RoHS requirements; the designation difference reflects the compliance standard version applied by each manufacturer.

Q: What is the significance of the 30mOhm contact resistance specification?

A: Contact resistance of 30mOhm is the maximum electrical resistance measured at the mating interface. This specification ensures reliable signal transmission and minimal voltage drop across the socket contacts. The TE Connectivity 1825375-2 and Assmann WSW A 28-LC-TT both specify 30mOhm; the 3M 4828-6000-CP does not provide this specification.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes, all three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. This simplifies inventory management and storage procedures across all three substitute options.

Q: What is the difference in termination post length between the parts?

A: The TE Connectivity 1825375-2 has a termination post length of 0.128" (3.24mm), while the Assmann WSW A 28-LC-TT has 0.124" (3.15mm). This 0.004" (0.09mm) difference is minimal and does not affect PCB compatibility for standard through-hole mounting. The 3M 4828-6000-CP does not specify post length.
