TE Connectivity AMP Connectors 2-641615-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-641615-4 is a 28-position DIP socket with 0.6" row spacing, gold-plated contacts, and through-hole solder termination. This component belongs to the Diplomate DL series and is classified as obsolete. The part features phosphor bronze contacts with gold mating finish and is designed for IC and transistor socket applications in electronic assemblies.

Due to the obsolete product status of the 2-641615-4, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Mill-Max Manufacturing Corp. parts 116-41-628-41-006000, 116-91-628-41-006000, and 116-93-628-41-006000 are active products that maintain full dimensional and functional compatibility with the 2-641615-4. These parts offer ROHS3 compliance (116-41 and 116-91 variants) or REACH Unaffected status, providing regulatory advantages over the obsolete original part. The Mill-Max series features beryllium copper mating contacts with gold finish, delivering superior contact resistance (10mOhm) compared to the original phosphor bronze design (30mOhm). All three Mill-Max variants support the full -55°C to 125°C operating temperature range and carry a 3A current rating.

Secondary Substitutes (Temperature/Rating Considerations):

The 3M 4828-6000-CP and 4828-6004-CP sockets maintain full dimensional compatibility and feature phosphor bronze contacts matching the original material specification. Both 3M parts are ROHS3 compliant and active products. However, these parts operate within a reduced temperature range of -25°C to 85°C and carry a 1A current rating, making them suitable only for applications within these thermal and electrical constraints. The tin contact finish differs from the original gold specification.

Alternative Substitute (Extended Temperature Range):

The Assmann WSW Components A 28-LC-TT socket provides ROHS3 compliance and active product status with phosphor bronze contacts and tin finish. This part supports an extended lower temperature limit of -55°C while maintaining an 85°C upper limit. The contact resistance specification of 30mOhm matches the original part. The 1A current rating and tin finish require application-level evaluation.

Compliance Considerations:

For applications requiring RoHS3 compliance, the Mill-Max 116-41-628-41-006000 and 116-91-628-41-006000 variants, the 3M 4828-6000-CP and 4828-6004-CP, and the Assmann A 28-LC-TT all provide compliant alternatives. The original 2-641615-4 and Mill-Max 116-93-628-41-006000 are RoHS non-compliant and should be selected only when legacy compliance status is required.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 116-41-628-41-006000 directly replace the TE Connectivity 2-641615-4 in existing PCB designs?

A: Yes. Both parts maintain identical 28-position DIP configuration, 0.6" row spacing, 0.100" pitch for mating and post, through-hole solder termination, and UL94 V-0 flammability rating. The Mill-Max part is a direct mechanical and electrical substitute. The beryllium copper contacts with gold finish provide improved contact resistance (10mOhm versus 30mOhm) and support the full -55°C to 125°C temperature range.

Q: What is the difference between the three Mill-Max substitute options (116-41, 116-91, and 116-93)?

A: All three Mill-Max parts share identical mechanical dimensions and electrical performance. The primary differences are in post finish specifications: 116-41-628-41-006000 features tin post finish, 116-91-628-41-006000 features tin-lead post finish, and 116-93-628-41-006000 features tin-lead post finish with a shorter termination post length of 0.108" versus 0.236" for the other variants. The 116-41 and 116-91 variants are ROHS3 compliant, while 116-93 is RoHS non-compliant.

Q: Are the 3M 4828-6000-CP and 4828-6004-CP suitable replacements for high-temperature applications?

A: No. The 3M parts operate within -25°C to 85°C, which is narrower than the original -55°C to 125°C range. These parts are suitable only for applications operating within the -25°C to 85°C window. For applications requiring the full -55°C to 125°C range, select the Mill-Max variants or the Assmann A 28-LC-TT (which supports -55°C to 85°C).

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

A: Contact finish affects corrosion resistance, contact resistance, and long-term reliability. The original 2-641615-4 and Mill-Max gold-plated variants provide superior corrosion resistance and lower contact resistance. The 3M and Assmann tin-finished options are suitable for standard industrial environments but may exhibit higher contact resistance over extended service life in corrosive conditions.

Q: Does the Assmann A 28-LC-TT provide a viable alternative to the original part?

A: The Assmann A 28-LC-TT is mechanically and functionally compatible with identical 28-position DIP configuration and 0.6" row spacing. It is ROHS3 compliant and active. However, it operates within -55°C to 85°C (versus the original -55°C to 125°C) and carries a 1A current rating. It is suitable for applications within these thermal and electrical constraints.

Q: What packaging format is used for these substitute parts?

A: All substitute parts are supplied in tube packaging, consistent with standard IC socket distribution methods. The original 2-641615-4 packaging specification was not provided in the technical data.

Q: Are all substitute parts MSL 1 (Unlimited) rated?

A: Yes. All identified substitute parts carry Moisture Sensitivity Level 1 (Unlimited), matching the original part specification. This indicates no moisture sensitivity precautions are required during storage or handling.

Q: Which substitute offers the best overall compatibility with the original 2-641615-4?

A: The Mill-Max 116-41-628-41-006000 provides the highest compatibility profile: active product status, ROHS3 compliance, full -55°C to 125°C operating range, superior contact resistance (10mOhm), 3A current rating, and gold-plated mating contacts. This part is the primary recommended substitute for direct replacement applications.
