• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 600VAC
• Series: MTA-156

The substitute part 3-644767-6 maintains complete electrical and mechanical compatibility with the original 644767-6 specification. Both components share identical connector architecture, contact configuration, and performance ratings. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The 3-644767-6 serves as a direct functional equivalent to the obsolete 644767-6 connector header. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting method, and operating ratings.

Product Status Consideration: The 644767-6 carries obsolete status, indicating discontinued manufacturing and limited availability. The 3-644767-6 maintains active product status with current manufacturing support and documented inventory availability.

Compliance Advantage: The 3-644767-6 achieves RoHS compliance, whereas the 644767-6 is RoHS non-compliant. This distinction becomes relevant for applications subject to RoHS regulatory requirements or customer specifications mandating compliant components.

Contact Finish Specification: The 3-644767-6 features tin post finish compared to the tin-lead finish of the 644767-6. Both finishes are compatible with solder termination processes and maintain equivalent electrical performance.

Packaging Format: The 3-644767-6 is supplied in bulk packaging, whereas the 644767-6 uses standard packaging. Packaging selection depends on procurement volume and inventory management requirements.

For new designs or component replenishment, the 3-644767-6 is the appropriate selection due to active product status and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 3-644767-6 directly replace the 644767-6 in existing applications?

A: Yes. The 3-644767-6 maintains complete electrical and mechanical compatibility with the 644767-6. All critical parameters including connector type, position count, pitch spacing, mounting configuration, and operating ratings are identical. The components are mechanically and electrically interchangeable.

Q: What is the significance of the different contact finish specifications?

A: The 644767-6 uses tin-lead post finish while the 3-644767-6 uses tin post finish. Both finishes are compatible with solder termination and provide equivalent electrical performance. The tin finish in the 3-644767-6 contributes to its RoHS compliance status.

Q: Why does the 644767-6 carry obsolete status?

A: Obsolete status indicates the manufacturer has discontinued production of this specific part number. The 3-644767-6 represents the current active equivalent, ensuring continued availability and manufacturing support.

Q: Are there packaging considerations when switching from 644767-6 to 3-644767-6?

A: The 644767-6 uses standard packaging while the 3-644767-6 is supplied in bulk format. Bulk packaging is suitable for high-volume procurement and may offer cost advantages. Packaging selection should align with procurement volume and inventory management practices.

Q: Does the RoHS compliance difference affect component performance?

A: No. RoHS compliance relates to material composition and regulatory adherence, not electrical or mechanical performance. Both components deliver identical functional performance. RoHS compliance becomes relevant only when design specifications or customer requirements mandate compliant components.

Q: Are both parts suitable for the same temperature and voltage operating conditions?

A: Yes. Both the 644767-6 and 3-644767-6 operate across the identical temperature range of -55°C to 105°C and are rated for 600VAC applications. Operating conditions are fully compatible.

Q: What applications are these connectors designed for?

A: Both components are specified for general purpose and industrial applications requiring board-to-cable/wire connections with through-hole mounting and solder termination.
