Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641207-8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (8)
• Pitch spacing (0.156" / 3.96mm)
• Voltage rating (600VAC)
• Operating temperature range (-55°C to 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 1 Wall)
• Contact length - mating (0.400" / 10.16mm)
• Contact length - post (0.125" / 3.18mm)
• Insulation height (0.300" / 7.62mm)
• Contact shape (Square)

Material and Certification Parameters:

• Insulation material (Thermoplastic, Glass Filled)
• Material flammability rating (UL94 V-0)
• Contact material (Copper Alloy)
• Series designation (MTA-156)

The substitute part 3-641207-8 maintains full equivalence across all electrical and mechanical parameters. Variations in product status, RoHS compliance, and contact finish post material do not affect functional interchangeability in applications where the original 641207-8 was specified.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641207-8 provides direct functional equivalence to the obsolete 641207-8 across all critical electrical and mechanical parameters. Selection of the substitute part is supported by the following engineering considerations:

Product Status: The 641207-8 is classified as obsolete, while the 3-641207-8 maintains active product status. This distinction ensures ongoing availability, technical support, and manufacturing consistency for new designs and replacement applications.

Compliance and Certifications: The substitute part 3-641207-8 achieves RoHS compliance, whereas the original 641207-8 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies these compliance mandates without compromising electrical or mechanical performance.

Contact Finish Post Material: The original part features Tin-Lead contact finish on the post, while the substitute employs Tin finish. Both finishes are compatible with solder termination processes and do not affect mating performance or electrical characteristics within the specified operating parameters.

Electrical and Mechanical Equivalence: All critical parameters determining connector functionality remain identical between the two parts, including pitch spacing, contact geometry, insulation dimensions, voltage rating, and temperature range. Direct substitution is supported without design modification.

Availability: The substitute part 3-641207-8 is available in bulk packaging with 709 pieces in current inventory, providing supply continuity for production and maintenance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-641207-8 be used as a direct replacement for the 641207-8 in existing designs?

A: Yes. The 3-641207-8 maintains identical electrical and mechanical specifications across all critical parameters, including connector type, contact configuration, pitch spacing, mounting type, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both Tin-Lead and Tin finishes are compatible with solder termination processes and provide equivalent electrical performance. The Tin finish on the substitute part represents a modern formulation that maintains solderability and contact reliability while eliminating lead content, supporting RoHS compliance objectives.

Q: Why is the 641207-8 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The substitute part 3-641207-8 provides equivalent functionality with active product status, ensuring ongoing availability and technical support.

Q: Does the RoHS compliance difference affect functional performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. The substitute part 3-641207-8 delivers identical functional performance while meeting RoHS requirements, making it suitable for applications with regulatory compliance mandates.

Q: Are there packaging differences between the two parts?

A: The original 641207-8 packaging is not specified in the technical data. The substitute part 3-641207-8 is available in bulk packaging. Both parts are identical in connector configuration and performance; packaging differences do not affect electrical or mechanical compatibility.

Q: What applications are these connectors suitable for?

A: Both the 641207-8 and 3-641207-8 are specified for general purpose and industrial applications. The 8-position, 0.156" pitch configuration with right-angle through-hole mounting supports board-to-cable/wire connections in control systems, instrumentation, and industrial equipment operating within the -55°C to 105°C temperature range.

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

A: Yes. Both parts carry a 600VAC voltage rating and UL94 V-0 material flammability certification, supporting use in industrial and general purpose applications within this voltage specification.

Q: Is the MTA-156 series designation important for compatibility?

A: Yes. The MTA-156 series designation identifies the connector family and ensures compatibility with corresponding mating connectors and accessories designed for this series. Both the 641207-8 and 3-641207-8 belong to the MTA-156 series and are fully compatible within this connector family.
