Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-100 rectangular connector family is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of positions: 4
• Pitch: 0.100" (2.54mm)
• Contact type: Male pin
• Wire gauge: 24 AWG
• Cable termination method: IDC

Mechanical Compatibility Parameters:

• Connector type: Plug
• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Latch holder
• Features: Closed end
• Color: White

Physical Specifications:

• Contact finish thickness: 80.0µin (2.03µm)
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 3-647001-4 maintains full equivalence across all electrical and mechanical parameters. The primary differentiation between the main part and its substitute is the contact finish material (tin-lead versus tin) and RoHS compliance status, along with packaging format and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Part 647001-4 (Main Part):

• Suitable for applications where tin-lead contact finish is specified or required
• RoHS non-compliant status restricts use in regulated environments requiring RoHS compliance
• Standard packaging format
• Lower inventory availability

Part 3-647001-4 (Substitute):

• Suitable for applications requiring RoHS compliance
• Tin contact finish provides alternative to tin-lead specification
• Bulk packaging format available
• Higher inventory availability supports production volume requirements
• Both parts maintain identical electrical and mechanical specifications within the MTA-100 series

Selection between these parts is determined by regulatory compliance requirements (RoHS status), contact finish material specification, packaging format needs, and inventory availability. Both parts are active products from TE Connectivity AMP Connectors and maintain full compatibility within the MTA-100 connector family.

Frequently Asked Questions (FAQ)

Q: Are the 647001-4 and 3-647001-4 connectors electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 4-position configuration, 0.100" (2.54mm) pitch, 24 AWG wire gauge, and IDC termination method. The electrical performance and mating characteristics are equivalent.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 647001-4 features tin-lead contact finish while the 3-647001-4 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The contact finish material affects RoHS compliance status and environmental performance characteristics.

Q: Why is the 647001-4 marked as RoHS non-compliant while 3-647001-4 is RoHS compliant?

A: The tin-lead contact finish in the 647001-4 contains lead, which is restricted under RoHS regulations. The 3-647001-4 uses tin contact finish, which complies with RoHS restrictions on hazardous substances.

Q: Can I use the 3-647001-4 as a direct replacement for the 647001-4 in existing designs?

A: Mechanical and electrical compatibility is maintained. The substitution is valid when RoHS compliance is required or when tin contact finish is acceptable for the application. Verify that the contact finish material change does not conflict with specific application requirements.

Q: What is the difference in packaging between these two parts?

A: The 647001-4 is supplied in standard packaging, while the 3-647001-4 is supplied in bulk packaging. Bulk packaging is typically used for high-volume production requirements.

Q: Are both parts currently available for procurement?

A: Yes. Both parts maintain active product status. The 647001-4 has 962 pieces in stock, while the 3-647001-4 has 11835 pieces in stock, providing higher availability for volume orders.

Q: Do both connectors have the same moisture sensitivity level?

A: Yes. Both the 647001-4 and 3-647001-4 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the mounting and fastening characteristics identical?

A: Yes. Both connectors feature free hanging (in-line) and right angle mounting types with latch holder fastening. The mechanical interface is fully compatible.
