Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 644694-7 is determined by the following critical parameters that must align across all candidate parts:

Primary Matching Criteria:

• Connector type classification as Header
• Contact type as Male Pin
• Exact position count of 7
• Identical mating pitch of 0.100" (2.54mm)
• Single row configuration
• Through-hole, right-angle mounting orientation
• Square contact shape
• Unshrouded design
• UL94 V-0 flammability rating
• Copper alloy contact material

The substitute parts 929500-01-07 and 929500-01-07-RK, both manufactured by 3M and part of the 929 series, satisfy all primary matching criteria. Both parts are classified as active products, providing long-term availability advantages over the obsolete 644694-7. The 3M alternatives maintain functional compatibility through identical pitch spacing, position count, mounting configuration, and contact geometry.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 644694-7 is classified as obsolete. Both 3M substitute parts (929500-01-07 and 929500-01-07-RK) maintain active product status, ensuring continued availability, manufacturing support, and supply chain reliability for new designs and production requirements.

Compliance and Certification: All three parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence. All parts carry UL94 V-0 flammability certification, meeting safety requirements for general-purpose applications.

RoHS Status: The TE Connectivity 644694-7 and both 3M alternatives are RoHS non-compliant. Applications requiring RoHS compliance cannot use any of these parts without design modification.

Temperature Operating Range: The TE Connectivity 644694-7 operates across -55°C to 105°C, while both 3M alternatives operate across -40°C to 105°C. Applications requiring operation below -40°C must retain the original TE Connectivity part.

Contact Geometry Variations: The 3M alternatives feature longer mating contact length (0.295" versus 0.260") and longer post length (0.130" versus 0.110"), with increased insulation height (0.110" versus 0.100"). These dimensional differences require mechanical fit verification in existing PCB layouts and mating connector designs.

Contact Finish Specifications: The 929500-01-07-RK variant provides thicker tin plating (200.0µin) compared to the original part (150.0µin Tin-Lead), offering enhanced corrosion resistance. The 929500-01-07 variant uses thinner tin-lead plating (100.0µin).

Frequently Asked Questions (FAQ)

Q: Can the 3M 929500-01-07 and 929500-01-07-RK parts be used interchangeably with the TE Connectivity 644694-7?

A: Both 3M parts satisfy the primary electrical and mechanical matching criteria: 7-position, 0.100" pitch, through-hole right-angle header configuration with male pins and square contacts. However, dimensional differences in contact length and insulation height require verification of mechanical fit within existing PCB layouts and mating connector designs before implementation.

Q: What are the key differences between the two 3M substitute options?

A: Both 929500-01-07 and 929500-01-07-RK share identical electrical specifications and mechanical dimensions. The primary difference is contact finish: 929500-01-07 uses Tin-Lead plating at 100.0µin thickness, while 929500-01-07-RK uses pure Tin plating at 200.0µin thickness. The 929500-01-07-RK variant offers thicker plating for enhanced durability. Additionally, 929500-01-07-RK has REACH Unaffected status, while 929500-01-07 is REACH Affected.

Q: Are there temperature limitations when substituting these parts?

A: Yes. The original TE Connectivity 644694-7 operates from -55°C to 105°C. Both 3M alternatives operate from -40°C to 105°C. Applications requiring operation below -40°C cannot use the 3M substitutes and must retain the original part.

Q: What packaging formats are available for these substitute parts?

A: The TE Connectivity 644694-7 is supplied in standard packaging. Both 3M alternatives (929500-01-07 and 929500-01-07-RK) are supplied in bulk packaging format.

Q: Do these parts meet RoHS compliance requirements?

A: No. The TE Connectivity 644694-7 and both 3M substitute parts are classified as RoHS non-compliant. Applications requiring RoHS compliance cannot use any of these parts.

Q: What is the current rating for these connectors?

A: The TE Connectivity 644694-7 current rating varies by wire gauge. The 3M alternatives are rated at 2.5A. Specific current capacity depends on the wire gauge used in the application.

Q: How do the insulation materials differ between these parts?

A: The TE Connectivity 644694-7 uses thermoplastic insulation. The 3M 929500-01-07 uses glass-filled polybutylene terephthalate (PBT) polyester. The 3M 929500-01-07-RK uses polycyclohexylenedimethylene terephthalate (PCT). All three materials carry UL94 V-0 flammability certification.

Q: What is the voltage rating for these connectors?

A: The TE Connectivity 644694-7 is rated for 250VAC. The 3M alternatives do not specify a voltage rating in the provided specifications.
