TE Connectivity 647106-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647106-4 is a rectangular connector header designed for surface mount applications. This component is a shrouded, single-row, 4-position connector with 0.100" (2.54mm) pitch spacing, suitable for board-to-cable/wire interconnections in general purpose applications. The part operates across an industrial temperature range of -55°C to 105°C with a 250VAC voltage rating.

The 647106-4 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for legacy systems or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 647106-4 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Style (Board to Cable/Wire)

Electrical & Environmental Compatibility:

• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (250VAC)
• Insulation material (Polyamide PA46, Nylon 4/6)
• Material flammability rating (UL94 V-0)

Regulatory & Compliance:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)
• REACH status

The substitute part 3-647106-4 maintains full equivalence across all critical parameters, with the primary distinction being product status (Active vs. Obsolete) and packaging configuration (Bulk vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-647106-4 serves as a direct functional equivalent to the obsolete 647106-4 model. Both components are manufactured by TE Connectivity within the MTA-100 series and maintain identical mechanical, electrical, and environmental specifications.

Product Status Consideration: The 647106-4 is classified as obsolete, while the 3-647106-4 maintains active product status. For new designs, production continuity, or component replenishment, the 3-647106-4 is the appropriate selection.

Compliance & Certification: Both parts satisfy RoHS compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling or storage conditions are required. Both maintain REACH Unaffected status and UL94 V-0 flammability certification.

Contact Finish Specification: The primary technical distinction is the contact finish on the post: the main part specifies Tin-Lead, while the substitute specifies Tin. Both finishes provide equivalent electrical and mechanical performance for solder termination applications.

Packaging Configuration: The substitute part is supplied in bulk packaging, whereas the main part uses standard packaging. Packaging selection should align with procurement and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-647106-4 be used as a direct replacement for the 647106-4 in existing designs?

A: Yes. The 3-647106-4 maintains full mechanical and electrical equivalence to the 647106-4 across all critical parameters including connector type, position count, pitch spacing, mounting method, operating temperature range, and voltage rating. The components are interchangeable at the functional level.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturing availability and supply chain support. The 647106-4 is obsolete and no longer manufactured. The 3-647106-4 is actively produced and represents the current equivalent offering from TE Connectivity. For ongoing production or new applications, the active part should be specified.

Q: Are there differences in the contact finish specifications?

A: The main part specifies Tin-Lead finish on the post contact, while the substitute specifies Tin finish. Both finishes are compatible with solder termination processes and provide equivalent electrical performance. The Tin finish on the substitute reflects current manufacturing standards and RoHS compliance practices.

Q: Does the bulk packaging of the 3-647106-4 affect compatibility?

A: Packaging format does not affect component compatibility or performance. Bulk packaging is a supply and handling consideration only. The electrical and mechanical specifications remain identical regardless of packaging configuration.

Q: Are both parts RoHS compliant?

A: Yes. The 647106-4 is ROHS3 Compliant, and the 3-647106-4 is RoHS Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

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

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. These components do not require special desiccant packaging, controlled humidity storage, or bake-out procedures prior to soldering.

Q: Can these connectors be used in high-temperature applications?

A: Both components are rated for operation across -55°C to 105°C. Applications within this temperature range are fully supported. The UL94 V-0 flammability rating of the insulation material provides additional thermal performance assurance.

Q: What is the voltage rating for these connectors?

A: Both the 647106-4 and 3-647106-4 are rated for 250VAC operation. Actual current capacity depends on wire gauge and application-specific thermal considerations.
