3M 4650-6300 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 4650-6300 is a 50-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications with wire gauges of 26-28 AWG. This connector features gold-plated contacts, feed-through capability, and latch lock/eject hook fastening. The product is active and widely used in industrial and telecommunications applications where reliable cable termination is required. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 4650-6300 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector Type & Position Count: Both substitutes maintain 50-position plug configuration
Pitch & Row Configuration: 0.100" (2.54mm) pitch with 2-row layout preserved across all parts
Cable Termination Method: IDC termination maintained for all substitutes
Wire Gauge Compatibility: 26-28 AWG wire gauge supported by all alternatives
Contact Finish: Gold plating with 30.0µin (0.76µm) thickness consistent across substitutes
Feed Through Capability: All parts support feed-through feature

The 3M 4650-6000 serves as a direct manufacturer-recommended substitute with identical electrical specifications and the same series designation. The TE Connectivity 1-111506-4 provides cross-manufacturer compatibility with equivalent electrical performance, though with differences in mounting type and packaging format.

Engineering Selection Recommendations

3M 4650-6000: This part is the manufacturer-recommended substitute and maintains complete electrical and mechanical equivalence to the 4650-6300. Both parts are ROHS3 compliant, REACH unaffected, and carry active product status. The 4650-6000 differs only in fastening type specification and is suitable for direct replacement in applications requiring identical performance characteristics.

TE Connectivity 1-111506-4: This cross-manufacturer substitute provides electrical compatibility with equivalent contact finish, pitch, and wire gauge specifications. The primary distinction is the panel mount configuration versus free hanging in-line mounting. This part is RoHS compliant and REACH unaffected. Selection of this substitute requires confirmation that panel mount orientation is compatible with the application's mechanical requirements.

All three parts maintain ECCN EAR99 classification and HTSUS code 8536.69.4051, supporting consistent regulatory and trade compliance across substitution options.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4650-6000 be used as a direct replacement for the 4650-6300?

A: Yes. Both parts share identical electrical specifications, including 50-position configuration, 0.100" pitch, IDC termination, 26-28 AWG wire gauge compatibility, and gold contact finish. Both are ROHS3 compliant and active products.

Q: What is the primary difference between the 3M 4650-6300 and TE Connectivity 1-111506-4?

A: The primary difference is mounting type: the 3M part is free hanging (in-line), while the TE Connectivity part is panel mount. Electrical specifications including position count, pitch, termination method, and contact finish are equivalent. The TE part also specifies ribbon cable only, whereas the 3M parts support discrete or ribbon cable.

Q: Are there packaging differences between these substitutes?

A: Yes. The 3M 4650-6300 and 4650-6000 are supplied in bulk packaging, while the TE Connectivity 1-111506-4 is supplied in tray packaging. This affects handling and inventory management but does not impact electrical or mechanical performance.

Q: Can the TE Connectivity 1-111506-4 be used in applications designed for the 3M 4650-6300?

A: Compatibility depends on the application's mechanical mounting requirements. The TE part's panel mount configuration differs from the 3M part's free hanging in-line design. Electrical compatibility is maintained, but physical installation method must be verified.

Q: Do all three parts meet the same regulatory standards?

A: All three parts are REACH unaffected and carry EAR99 ECCN classification. The 3M parts are ROHS3 compliant, while the TE part is RoHS compliant. Both compliance levels are acceptable for most applications.

Q: What wire types are compatible with each substitute?

A: The 3M 4650-6300 and 4650-6000 support both discrete and ribbon cable with 26-28 AWG wire gauge in stranded or solid form. The TE Connectivity 1-111506-4 is specified for ribbon cable only with 26-28 AWG wire gauge.
