3M 4650-7201 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4650-7201 is a 50-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications. This connector features gold-plated contacts rated for 26-28 AWG wire gauges and employs latch lock/eject hook fastening. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, lead time requirements, or specific fastening preferences necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4650-7201 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug with male pin contacts
• Position Count & Pitch: 50 positions at 0.100" (2.54mm) pitch in 2-row configuration
• Termination Method: IDC cable termination
• Wire Compatibility: 26-28 AWG, stranded or solid wire
• Contact Material & Finish: Gold plating at 30.0µin thickness
• Electrical & Environmental Compliance: ROHS3 compliance and MSL 1 rating

The identified substitute part 4650-6001 maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction lies in the fastening mechanism: the 4650-7201 incorporates latch lock/eject hooks (short), while the 4650-6001 features feed-through design without specified fastening hardware. Both parts share identical contact configuration, pitch, termination method, and wire gauge specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4650-7201 and 4650-6001 are active production parts with full ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts depends on fastening requirements specific to the application:

• 4650-7201: Select when latch lock/eject hook fastening is required for secure mating and positive retention in the connector interface.
• 4650-6001: Select when feed-through design is compatible with the application and when higher inventory availability is a consideration.

Both parts maintain identical electrical performance, contact configuration, and environmental compliance. The choice between them is determined solely by mechanical fastening compatibility with the mating connector or application assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can 4650-6001 be used as a direct replacement for 4650-7201?

A: Electrical and mechanical compatibility is maintained across all critical parameters including position count, pitch, contact type, wire gauge, and contact finish. The primary difference is the fastening mechanism. Compatibility depends on whether the application requires latch lock/eject hook fastening or can accommodate feed-through design.

Q: Are the contact configurations identical between these parts?

A: Yes. Both parts feature 50 male pin contacts arranged in 2 rows at 0.100" pitch with identical gold plating specifications and IDC termination capability.

Q: What wire gauges are supported by both connectors?

A: Both the 4650-7201 and 4650-6001 support 26-28 AWG wire in stranded or solid configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating.

Q: What is the primary functional difference between these substitute parts?

A: The fastening mechanism differs. The 4650-7201 incorporates latch lock/eject hooks for positive retention, while the 4650-6001 uses feed-through design. All other electrical and mechanical specifications are equivalent.

Q: Can these connectors be used with ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination via IDC method.
