Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4640-6305 is determined by the following critical parameters:

Electrical Compatibility: 40-position configuration, 0.100" pitch, 2-row layout, IDC termination method, 26-28 AWG wire gauge support, and gold contact finish with 30.0µin thickness
Mechanical Compatibility: Plug connector type with male pin contacts, feed-through capability, and latch lock/eject hook fastening
Compliance: ROHS3 compliance and EAR99 ECCN classification

The identified substitute parts maintain these core specifications while varying in mounting type, fastening hook configuration, packaging format, and color. All substitutes are active products with equivalent electrical performance and termination compatibility.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 3M 4640-6305 specification. Selection between substitutes should be based on application-specific requirements:

3M 4640-6000: Differs from the main part by omitting fastening type specification and offering unlimited moisture sensitivity level (MSL 1). This variant provides equivalent electrical and mechanical performance for applications where fastening hook configuration is not a constraint.

3M 4640-6300: Maintains identical fastening type (Latch Lock/Eject Hooks, Long) and all electrical specifications as the main part. This substitute offers direct functional equivalence with unlimited moisture sensitivity level (MSL 1).

TE Connectivity 2-111506-4: Provides equivalent 40-position IDC connectivity with additional strain relief feature. This part differs in mounting type (Panel Mount versus Free Hanging), fastening hook configuration (standard versus long), packaging format (Tray versus Bulk), and connector color (Black versus Gray). The AMP-Latch series maintains all critical electrical parameters and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can 4640-6000 be used as a direct replacement for 4640-6305?

A: Yes. Both parts share identical electrical specifications: 40-position configuration, 0.100" pitch, 2-row layout, IDC termination, 26-28 AWG wire gauge support, and gold contact finish. The primary difference is fastening type specification, which does not affect electrical compatibility.

Q: What is the key difference between 4640-6300 and 4640-6305?

A: Both parts are electrically and mechanically equivalent. The 4640-6300 maintains the same latch lock/eject hook fastening configuration as the 4640-6305. The difference lies in moisture sensitivity level classification (MSL 1 Unlimited for 4640-6300 versus MSL Not Applicable for 4640-6305).

Q: Is the TE Connectivity 2-111506-4 compatible with applications designed for the 3M 4640-6305?

A: The 2-111506-4 maintains electrical compatibility through identical 40-position IDC configuration, pitch, row spacing, wire gauge, and contact finish specifications. However, it differs in mounting type (Panel Mount versus Free Hanging) and packaging format (Tray versus Bulk). Application compatibility depends on whether the mounting type change is acceptable for the specific installation.

Q: What does "Feed Through" feature mean?

A: Feed Through indicates that the connector allows signal or power to pass through the connector body, enabling daisy-chain or multi-point connection configurations in ribbon cable applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (4640-6000, 4640-6300, and 2-111506-4) are ROHS3 compliant, matching the regulatory status of the main part 4640-6305.

Q: What is the significance of contact finish thickness (30.0µin)?

A: Contact finish thickness of 30.0µin (0.76µm) specifies the gold plating depth on connector contacts. All listed parts maintain this specification, ensuring consistent electrical performance and contact reliability across substitutes.
