3M 4650-6305 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The 3M 4650-6305 is a 50-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for 26-28 AWG wire gauges in both stranded and solid configurations. This connector features gold-plated contacts, a 0.100" pitch in a 2-row configuration, and feed-through capability with latch lock/eject hook fastening.

The 4650-6305 is classified as obsolete. Equivalent substitute parts are available in active product status, providing direct functional replacement while maintaining all critical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the 4650-6305 is determined by strict equivalence across the following critical parameters:

Connector Configuration: 50 positions, 2 rows, 0.100" pitch and row spacing
Contact System: Male pin, gold-plated contacts at 30.0µin thickness
Termination Method: IDC cable termination for 26-28 AWG wire
Mechanical Interface: Free hanging in-line mounting with feed-through capability
Compliance: ROHS3 compliance and EAR99 ECCN classification

The substitute parts 4650-6000 and 4650-6300 maintain identical electrical and mechanical specifications across all these parameters. The primary distinction between parts relates to product status (active vs. obsolete) and fastening type configuration, which does not affect functional interchangeability in applications requiring the 4650-6305 specification.

Engineering Selection Recommendations

Both 4650-6000 and 4650-6300 are qualified substitutes for the obsolete 4650-6305 based on complete parameter equivalence.

4650-6000: This part is the manufacturer-recommended primary substitute. It maintains active product status with full ROHS3 compliance and REACH unaffected designation. The fastening type is not specified in available documentation, which may require verification against application requirements if fastening mechanism is a critical design parameter.

4650-6300: This part provides an alternative substitute with identical specifications to the 4650-6305, including the specified latch lock/eject hook fastening type. It maintains active product status with ROHS3 compliance and REACH unaffected designation, making it suitable for applications where fastening type consistency with the original part is required.

Selection between 4650-6000 and 4650-6300 should be based on fastening type requirements and application-specific mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can 4650-6000 and 4650-6300 be used interchangeably with 4650-6305?

A: Both parts are functionally equivalent to 4650-6305 across all critical electrical and mechanical parameters: 50-position configuration, 0.100" pitch, 2-row layout, IDC termination for 26-28 AWG wire, gold contact finish, and feed-through capability. The primary difference is fastening type specification, which does not affect electrical performance or physical mating interface.

Q: What is the difference between 4650-6000 and 4650-6300?

A: Both parts are electrically and mechanically identical. The documented difference is fastening type: 4650-6300 specifies latch lock/eject hooks (long), matching the 4650-6305 specification, while 4650-6000 does not specify fastening type in available documentation.

Q: Why is 4650-6305 listed as obsolete?

A: The 4650-6305 has been superseded by active production alternatives. The 4650-6000 and 4650-6300 provide equivalent functionality and are recommended for new designs and replacement applications.

Q: Are there any compliance differences between these parts?

A: All three parts maintain ROHS3 compliance and EAR99 ECCN classification. The 4650-6000 and 4650-6300 additionally carry REACH unaffected designation, confirming regulatory alignment for current procurement.

Q: What packaging options are available?

A: The 4650-6305 is supplied in standard packaging. The 4650-6000 and 4650-6300 are supplied in bulk packaging, which may affect procurement quantities and handling procedures.
