Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by alignment of critical electrical and mechanical parameters. The primary substitution criteria for the TE Connectivity 3-644457-9 are:

Critical Matching Parameters:

• Pitch spacing: 0.100" (2.54mm)
• Number of positions: 9
• Number of rows: 1
• Contact type: Male Pin
• Mounting configuration: Through Hole, Right Angle
• Termination method: Solder
• Contact material: Copper Alloy
• Flammability rating: UL94 V-0

The 3M 929500-01-09-RK satisfies these core electrical and mechanical requirements, enabling functional equivalence in applications requiring 9-position, 2.54mm pitch header connectors with right-angle through-hole mounting and solder termination.

Engineering Selection Recommendations

TE Connectivity 3-644457-9 Selection Criteria:

• Applications requiring operating temperatures below -40°C
• Designs where RoHS3 compliance documentation is mandatory
• Systems with defined moisture sensitivity level requirements
• Applications utilizing thermoplastic insulation material specifications
• Designs with specific contact length requirements of 0.260" (6.60mm) mating length

3M 929500-01-09-RK Selection Criteria:

• Applications operating within -40°C to 105°C temperature range
• Designs benefiting from breakaway connector functionality
• Systems where extended contact lengths (0.295" mating, 0.130" post) provide mechanical advantage
• Applications where push-pull fastening type is advantageous
• Designs utilizing PCT insulation material

Both components maintain Active product status and UL94 V-0 flammability compliance, supporting continued use in production environments. Selection between these parts is determined by specific application requirements regarding temperature extremes, insulation material properties, contact geometry, and regulatory compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929500-01-09-RK directly replace the TE Connectivity 3-644457-9 in all applications?

A: Direct replacement is possible for applications operating within the -40°C to 105°C temperature range. Applications requiring operation below -40°C require the TE Connectivity part. Physical board layout must accommodate the 3M part's longer contact lengths (0.295" mating vs. 0.260" mating) and greater insulation height (0.110" vs. 0.100").

Q: What are the key electrical compatibility factors between these parts?

A: Both connectors feature identical pitch spacing (0.100"/2.54mm), 9-position configuration, male pin contact type, square contact shape, copper alloy material, and tin contact finish. Both maintain UL94 V-0 flammability rating and support solder termination. Voltage and current ratings differ; verify application requirements against each part's specifications.

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

A: The TE Connectivity 3-644457-9 uses thermoplastic insulation, while the 3M 929500-01-09-RK uses polycyclohexylenedimethylene terephthalate (PCT). Both materials achieve UL94 V-0 rating. Material selection impacts chemical resistance, dimensional stability, and thermal properties; application environment determines suitability.

Q: Are there packaging or inventory considerations for these parts?

A: Both parts are available in bulk packaging. TE Connectivity 3-644457-9 inventory: 958 pieces. 3M 929500-01-09-RK inventory: 980 pieces. Moisture sensitivity level differs; TE Connectivity specifies MSL 1 (Unlimited), while 3M specifies Not Applicable.

Q: What mechanical differences exist between these connectors?

A: Contact length differences are present: TE Connectivity mating contact 0.260" (6.60mm) versus 3M mating contact 0.295" (7.49mm); TE Connectivity post length 0.110" (2.79mm) versus 3M post length 0.130" (3.30mm). Insulation height: TE Connectivity 0.100" (2.54mm) versus 3M 0.110" (2.79mm). These dimensional variations require PCB layout verification before substitution.

Q: Which part is suitable for low-temperature applications?

A: The TE Connectivity 3-644457-9 supports operating temperatures from -55°C to 105°C, making it suitable for low-temperature environments. The 3M 929500-01-09-RK operates from -40°C to 105°C and is not suitable for applications below -40°C.

Q: What is the significance of the breakaway feature on the 3M connector?

A: The 3M 929500-01-09-RK includes breakaway functionality, allowing individual positions to be separated if required. The TE Connectivity 3-644457-9 does not feature this capability. This distinction affects design flexibility for applications requiring modular connector configurations.
