TE Connectivity AMP Connectors 2-641260-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-641260-1 is an 8-position DIP socket with 0.3" (7.62mm) row spacing, tin contact finish, and through-hole solder termination. This component belongs to the Diplomate DL series and is classified as obsolete. The part features a closed frame design with beryllium copper contacts and thermoplastic glass-filled housing rated UL94 V-0.

Due to the obsolete product status of the 2-641260-1, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the 2-641260-1 is determined by the following critical parameters:

Primary Matching Criteria:

Number of Positions: 8 (2 x 4)
Row Spacing: 0.3" (7.62mm)
Pitch - Mating: 0.100" (2.54mm)
Pitch - Post: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Contact Finish: Tin
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Considerations:

Operating Temperature Range (minimum -55°C required)
Contact Resistance (30mOhm baseline)
Contact Material (Phosphor Bronze acceptable as functional equivalent to Beryllium Copper)

The substitute parts 4808-3000-CP, 4808-3004-CP, A 08-LC-TT, and ICS-308-T meet all primary matching criteria and are therefore direct functional equivalents. The part ICS-328-T does not qualify as a substitute due to position count mismatch (28 positions versus 8 positions required).

Engineering Selection Recommendations

Primary Substitute: ICS-308-T (Adam Tech)

The ICS-308-T is the optimal substitute for the obsolete 2-641260-1. This part maintains full compatibility across all critical electrical and mechanical parameters, including identical operating temperature range (-55°C ~ 105°C), matching contact resistance specification (20mOhm), and equivalent RoHS3 compliance. The ICS-308-T is currently in active production status with substantial inventory availability (14,628 pieces).

Secondary Substitutes: 4808-3004-CP and 4808-3000-CP (3M)

Both 3M parts from the 4800 series provide functional equivalence with identical position count, row spacing, pitch, and mounting configuration. These parts are actively manufactured with high inventory levels (53,828 and 1,436 pieces respectively). The primary design consideration is the reduced operating temperature range (-25°C ~ 85°C), which limits application in systems requiring full -55°C to 105°C operation. Contact resistance specifications are not provided for these parts.

Tertiary Substitute: A 08-LC-TT (Assmann WSW Components)

The A 08-LC-TT offers full mechanical and electrical compatibility with operating temperature range of -55°C ~ 85°C. This part maintains the 30mOhm contact resistance specification and is actively produced with 7,113 pieces in inventory. The operating temperature upper limit of 85°C represents a constraint for applications requiring 105°C operation.

Non-Qualifying Part: ICS-328-T (Adam Tech)

The ICS-328-T is not a substitute for the 2-641260-1 due to fundamental position count incompatibility (28 positions versus 8 positions). This part cannot be used as a direct replacement.

Frequently Asked Questions (FAQ)

Q: Can the 4808-3004-CP or 4808-3000-CP be used in applications requiring -55°C operation?

A: No. Both 3M parts specify a minimum operating temperature of -25°C. Applications requiring -55°C operation must use either the ICS-308-T, A 08-LC-TT, or the original 2-641260-1 specification.

Q: What is the difference between the 4808-3004-CP and 4808-3000-CP?

A: Both parts are functionally identical 8-position DIP sockets from the 3M 4800 series with matching electrical and mechanical specifications. The primary difference is inventory availability, with the 4808-3004-CP having significantly higher stock levels (53,828 versus 1,436 pieces).

Q: Is the contact material difference between Beryllium Copper and Phosphor Bronze significant?

A: Both materials are acceptable for DIP socket applications and provide equivalent electrical performance in standard IC socket applications. The contact resistance specifications of the substitute parts (20mOhm for ICS-308-T, 30mOhm for A 08-LC-TT) are within acceptable tolerance of the original 30mOhm specification.

Q: Can the ICS-328-T be modified to work as an 8-position socket?

A: No. The ICS-328-T is a 28-position socket with fundamentally different mechanical geometry and cannot be modified for 8-position applications. The 28-position configuration is not interchangeable with 8-position DIP sockets.

Q: Which substitute part has the best long-term availability?

A: The ICS-308-T from Adam Tech is recommended for long-term design continuity. This part is in active production status with the broadest operating temperature range (-55°C ~ 105°C) matching the original specification, and maintains current inventory levels of 14,628 pieces.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (4808-3004-CP, 4808-3000-CP, A 08-LC-TT, and ICS-308-T) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original 2-641260-1 compliance status.

Q: What is the significance of the "Closed Frame" versus "Open Frame" design?

A: The original 2-641260-1 features a closed frame design, while all substitute parts feature open frame designs. Both designs accommodate standard DIP package insertion and provide equivalent mechanical retention. The frame design does not affect electrical performance or pin pitch compatibility.
