Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 644613-5 and the identified substitute 3-644613-5 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type, contact type, and mating pitch (0.156" / 3.96mm)
• Number of positions (5) and row configuration (1 row)
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Copper Alloy) and contact shape (Square)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)
• Contact dimensions (Mating: 0.450" / 11.43mm; Post: 0.125" / 3.18mm)
• Insulation height (0.300" / 7.62mm)
• Insulation material (Thermoplastic, Glass Filled)

Regulatory & Environmental Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.4040)

The substitute part differs only in packaging format (Bulk versus standard packaging) and contact finish specification (Tin versus Tin-Lead), with corresponding differences in RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Part 644613-5 (Main Part):

• Product Status: Active
• RoHS Status: RoHS non-compliant
• Contact Finish: Tin-Lead
• Packaging: Standard
• Inventory: 743 Pcs New Original In Stock

Part 3-644613-5 (Substitute):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Contact Finish: Tin
• Packaging: Bulk
• Inventory: 1988 Pcs New Original In Stock

Both parts are electrically and mechanically equivalent within the MTA-156 connector family. Selection between these parts is determined by regulatory compliance requirements and packaging needs. The 3-644613-5 substitute is suitable for applications requiring ROHS3 compliance. The 644613-5 main part is suitable for applications where RoHS compliance is not mandated. The contact finish difference (Tin-Lead versus Tin) does not affect functional compatibility, as both finishes meet the specified 150.0µin (3.81µm) thickness requirement and provide equivalent electrical performance at 600VAC.

Frequently Asked Questions (FAQ)

Q: Are the 644613-5 and 3-644613-5 connectors electrically interchangeable?

A: Yes. Both connectors are electrically equivalent. They share identical voltage rating (600VAC), operating temperature range (-55°C ~ 105°C), contact material (Copper Alloy), and contact finish thickness (150.0µin / 3.81µm). The contact finish composition difference (Tin-Lead versus Tin) does not affect electrical performance.

Q: Are the 644613-5 and 3-644613-5 connectors mechanically interchangeable?

A: Yes. Both connectors are mechanically equivalent. They share identical mating pitch (0.156" / 3.96mm), number of positions (5), mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 1 Wall), contact dimensions, and insulation specifications.

Q: What is the difference between the 644613-5 and 3-644613-5?

A: The primary differences are packaging format (Standard versus Bulk) and RoHS compliance status (RoHS non-compliant versus ROHS3 Compliant). The contact finish specification also differs (Tin-Lead versus Tin), but both finishes meet identical thickness requirements and provide equivalent performance.

Q: Which part should I select for RoHS-compliant applications?

A: The 3-644613-5 is ROHS3 Compliant and is the appropriate selection for applications requiring RoHS compliance. The 644613-5 is RoHS non-compliant.

Q: Can I use the 3-644613-5 in place of the 644613-5 in existing designs?

A: Yes. The 3-644613-5 is a direct substitute for the 644613-5. All electrical and mechanical parameters are equivalent. The substitution is valid for board-to-cable/wire applications within the specified operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC).

Q: What does "Bulk" packaging mean for the 3-644613-5?

A: Bulk packaging indicates the connector is supplied in a bulk format rather than standard packaging. This affects order quantity and handling but does not alter the connector's electrical or mechanical specifications.

Q: Are both parts suitable for industrial applications?

A: Yes. Both the 644613-5 and 3-644613-5 are rated for general purpose and industrial applications. Both meet UL94 V-0 material flammability requirements and are classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge. The connector specifications do not define a fixed current rating independent of the wire gauge used in the mating cable/wire assembly.
