CNC Tech 243-48-1-06 Equivalent & Substitute Parts

Part Overview

The CNC Tech 243-48-1-06 is a 48-position DIP socket with 0.6" row spacing, designed for through-hole mounting of dual inline package integrated circuits and transistors. This component features tin-plated phosphor bronze contacts and is housed in glass-filled polybutylene terephthalate material rated UL94 V-0. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing production support and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CNC Tech 243-48-1-06 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• 48-position configuration (2 x 24 arrangement)
• 0.6" (15.24mm) row spacing
• 0.100" (2.54mm) mating and post pitch
• Through-hole mounting type
• Open frame design

Electrical Compatibility:

• Tin contact finish on both mating and post surfaces
• Phosphor bronze contact material
• 1 A current rating
• Solder termination

Environmental & Compliance:

• UL94 V-0 flammability rating
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity

The 3M 4848-6000-CP meets all mechanical and electrical compatibility requirements for direct substitution. Both components share identical position count, pitch specifications, contact materials, and current ratings. Housing material differs (polyester versus polybutylene terephthalate), but both are glass-filled and maintain equivalent UL94 V-0 ratings.

Parameter Comparison

Engineering Selection Recommendations

The 3M 4848-6000-CP is a direct functional equivalent to the obsolete CNC Tech 243-48-1-06 for applications requiring 48-position DIP socket functionality. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

The primary consideration for selection is operating temperature range. The CNC Tech part supports -40°C to 105°C, while the 3M substitute operates within -25°C to 85°C. Applications requiring operation below -25°C or above 85°C must evaluate thermal performance requirements against the narrower operating window of the substitute.

The 3M 4848-6000-CP offers the advantage of active product status, ensuring continued availability and supply chain support. The housing material difference (polyester versus polybutylene terephthalate) does not affect electrical or mechanical compatibility, as both materials are glass-filled and maintain equivalent flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4848-6000-CP directly replace the CNC Tech 243-48-1-06 in existing designs?

A: Yes, for applications operating within the -25°C to 85°C temperature range. Both components share identical mechanical pitch, position count, contact materials, and electrical ratings. Verify that your application does not require the extended low-temperature performance of the original part.

Q: What is the difference in housing material between these two sockets?

A: The CNC Tech part uses polybutylene terephthalate (PBT) while the 3M part uses polyester. Both are glass-filled and rated UL94 V-0. This material difference does not affect electrical performance or mechanical compatibility in standard through-hole PCB applications.

Q: Are both parts RoHS compliant?

A: Yes, both the CNC Tech 243-48-1-06 and 3M 4848-6000-CP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of the operating temperature range difference?

A: The CNC Tech part operates from -40°C to 105°C, while the 3M substitute operates from -25°C to 85°C. If your application requires operation below -25°C or above 85°C, the substitute may not be suitable. Confirm your application's thermal requirements before selection.

Q: Why is the CNC Tech part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 3M 4848-6000-CP, with active product status, provides ongoing supply availability for equivalent functionality.

Q: Are the contact resistance specifications comparable?

A: The CNC Tech part specifies 20mOhm contact resistance. The 3M part does not provide this specification in the available data. Both use identical phosphor bronze contact materials and tin plating, which typically deliver comparable electrical performance in standard applications.
