Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 644894-6 is based on electrical and mechanical parameter equivalence within the CST-100 series. The substitute part 3-644894-6 maintains identical specifications across all critical dimensions and functional parameters:

Key Substitution Parameters:

• Connector type, contact type, and position count (Header, Male Pin, 6-position)
• Mating pitch and contact geometry (0.100" spacing, square contact shape)
• Mounting configuration (Through Hole, Right Angle, Shrouded - 4 Wall)
• Contact dimensions (Mating length 0.280", Post length 0.130", Insulation height 0.313")
• Electrical ratings (250VAC, -55°C ~ 105°C operating range)
• Termination and fastening methods (Solder, Friction Lock)
• Material compliance (UL94 V-0 flammability rating)

The substitute part differs only in product status (Active versus Obsolete), packaging configuration (Bulk versus standard), contact finish specification (Tin versus Tin-Lead), and regulatory compliance status (RoHS Compliant and REACH Unaffected versus Not Applicable). These differences do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-644894-6 is the direct functional equivalent of the obsolete 644894-6 model. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 644894-6 is classified as obsolete, while the substitute 3-644894-6 maintains active product status with current manufacturing support and documented availability.

Regulatory Compliance: The substitute part 3-644894-6 carries RoHS Compliant certification and REACH Unaffected status, providing enhanced regulatory alignment for applications subject to environmental and hazardous substance restrictions. The main part lists RoHS status as Not Applicable and REACH status as Vendor Undefined.

Contact Finish Specification: The substitute part features pure Tin contact finish on both mating and post surfaces, compared to the Tin-Lead finish of the main part. Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance in board-to-cable/wire connection applications.

Mechanical and Electrical Equivalence: All critical mechanical dimensions, electrical ratings, operating temperature range, voltage specifications, and material properties are identical between the main part and substitute. Both components are manufactured by TE Connectivity within the CST-100 series and maintain identical shrouding, mounting configuration, and contact geometry.

Application Continuity: The substitute part maintains full compatibility with existing circuit designs, PCB layouts, and mating connector specifications. No design modifications are required for component substitution in general purpose and lighting applications.

Frequently Asked Questions (FAQ)

Q: Can the 3-644894-6 be used as a direct replacement for the 644894-6 in existing designs?

A: Yes. The 3-644894-6 is a direct functional equivalent with identical electrical and mechanical specifications. All critical parameters including connector type, position count, pitch spacing, mounting configuration, contact dimensions, and electrical ratings are identical. No design modifications are required.

Q: What is the difference between the Tin-Lead finish on the main part and the Tin finish on the substitute?

A: Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance. The Tin finish on the substitute part reflects current manufacturing standards and RoHS compliance requirements. The contact material (Copper Alloy) and overall electrical characteristics remain unchanged.

Q: Why is the main part 644894-6 classified as obsolete?

A: The obsolete status indicates that the part is no longer in active production. The substitute part 3-644894-6 represents the current active equivalent within the CST-100 series and is recommended for new designs and ongoing production requirements.

Q: Are there packaging differences between the two parts?

A: The main part 644894-6 is listed with standard packaging, while the substitute 3-644894-6 is supplied in Bulk packaging. Both configurations contain identical components; packaging differences do not affect functional performance or interchangeability.

Q: What is the operating temperature range for both parts?

A: Both the 644894-6 and 3-644894-6 operate across the identical temperature range of -55°C to 105°C, suitable for general purpose and lighting applications across standard industrial and commercial environments.

Q: Do both parts meet the same electrical and safety standards?

A: Yes. Both parts carry identical voltage ratings (250VAC), current ratings (Varies by Wire Gauge), and material flammability certification (UL94 V-0). The substitute part additionally carries RoHS Compliant and REACH Unaffected certifications, providing enhanced regulatory documentation.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates minimal moisture sensitivity and no special storage or handling requirements during component storage and assembly processes.

Q: Are the contact dimensions identical between the two parts?

A: Yes. Both parts maintain identical contact geometry with mating contact length of 0.280" (7.11mm), post contact length of 0.130" (3.30mm), and insulation height of 0.313" (7.95mm). These dimensions ensure mechanical compatibility with existing mating connectors and PCB layouts.
