3M 4634-6305 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 4634-6305 is a 34-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 4634-6305 is classified as obsolete. Equivalent substitute parts are available in active product status, offering identical electrical and mechanical specifications with improved availability and current manufacturing support.

Substitute Part Grouping Explanation

Substitute parts for the 4634-6305 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector Type & Position Count: Plug configuration with 34 positions
Contact Configuration: Male pin contacts in 2-row arrangement
Pitch & Spacing: 0.100" (2.54mm) pitch and row spacing
Termination Method: IDC cable termination for 26-28 AWG wire
Contact Material & Finish: Gold plating at 30.0µin thickness
Mounting & Fastening: Free hanging in-line mounting
Compliance: ROHS3 compliance and MSL rating

The substitute parts 4634-6000 and 4634-6300 maintain all critical electrical and mechanical parameters. The primary distinction is product status: 4634-6000 and 4634-6300 are active products with current manufacturing support, whereas 4634-6305 is obsolete.

Engineering Selection Recommendations

Both 4634-6000 and 4634-6300 are direct functional equivalents to the 4634-6305. Selection between these active alternatives should be based on the following factors:

4634-6300: Retains the latch lock/eject hook fastening specification identical to the 4634-6305. This option is recommended for applications where the fastening mechanism is a design requirement.

4634-6000: Specified without fastening type designation. This option provides equivalent electrical and mechanical performance for applications where fastening mechanism is not a critical parameter.

Both substitute parts carry ROHS3 compliance and are manufactured by 3M within the 4600 series. Current inventory availability and packaging requirements (bulk) should be evaluated against application needs.

Frequently Asked Questions (FAQ)

Q: Are 4634-6000 and 4634-6300 electrically identical to 4634-6305?

A: Yes. All three connectors share identical electrical specifications: 34-position IDC termination, gold contact finish at 30.0µin thickness, 26-28 AWG wire gauge compatibility, and 0.100" pitch configuration.

Q: What is the difference between 4634-6000 and 4634-6300?

A: The primary difference is the fastening type. The 4634-6300 specifies latch lock/eject hook fastening, matching the 4634-6305 design. The 4634-6000 does not specify a fastening type. Both maintain identical contact configuration, pitch, and termination method.

Q: Can I use 4634-6000 or 4634-6300 as a direct replacement for 4634-6305?

A: Yes, both are direct substitutes. The 4634-6305 is obsolete; 4634-6000 and 4634-6300 are active products with current manufacturing support. Mechanical fit and electrical performance are equivalent.

Q: Are there packaging differences between these parts?

A: The 4634-6305 packaging is not specified in available data. Both 4634-6000 and 4634-6300 are supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do all three connectors meet the same compliance standards?

A: Yes. All three are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8536.69.4051). MSL rating for 4634-6305 is 1 (Unlimited); 4634-6300 MSL is Not Applicable.

Q: Which substitute should I select for new designs?

A: For new designs, either 4634-6000 or 4634-6300 is appropriate. If your application requires latch lock/eject hook fastening, specify 4634-6300. If fastening mechanism is not a design constraint, 4634-6000 offers equivalent performance.
