Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1744214-8 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Voltage rating of 250VAC and operating temperature range of -55°C to 105°C must be maintained.

Mechanical Parameters: Number of positions (8), pitch spacing (0.100" / 2.54mm), connector type (header), contact type (male pin), mounting method (through hole), shrouding configuration (shrouded - 1 wall), and fastening type (friction lock) must remain identical.

Physical Dimensions: Contact length specifications (mating: 0.295", post: 0.140", overall: 0.535"), insulation height (0.305"), and contact shape (square) must match.

Material and Compliance: Contact material (copper alloy), insulation material (thermoplastic), contact finish (tin), and flammability rating (UL94 V-0) must be consistent.

Series Designation: The MTA-100 series classification must be preserved.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 640456-8 is a direct functional equivalent to the 1744214-8. All electrical, mechanical, and dimensional parameters are identical across both parts. Both connectors operate within the same temperature range (-55°C to 105°C), maintain the same voltage rating (250VAC), and share identical physical dimensions and contact specifications.

The primary distinction between these parts is product status: the 1744214-8 is classified as obsolete, while the 640456-8 maintains active status. Both parts meet RoHS compliance requirements and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).

For new designs or applications requiring continued supply assurance, the 640456-8 is the appropriate selection. For existing applications currently using the 1744214-8, direct substitution with the 640456-8 is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 640456-8 be used as a direct replacement for the 1744214-8 in existing applications?

A: Yes. The 640456-8 is electrically and mechanically equivalent to the 1744214-8. All critical parameters including connector type, position count, pitch spacing, mounting method, contact specifications, and operating ratings are identical. Direct substitution is supported without circuit board redesign or connector interface modification.

Q: What is the primary reason for substituting the 1744214-8?

A: The 1744214-8 carries an obsolete product status. The 640456-8 is the active equivalent part, ensuring continued availability and supply chain support for applications requiring this connector type.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance status. The 1744214-8 is ROHS3 compliant, and the 640456-8 is RoHS compliant. Both carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both meet UL94 V-0 flammability requirements.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control measures. Standard component storage practices are sufficient.

Q: Are the physical dimensions and contact lengths identical between these parts?

A: Yes. Contact length specifications (mating: 0.295", post: 0.140", overall: 0.535"), insulation height (0.305"), and all other dimensional parameters are identical. PCB footprints and mating interface dimensions are equivalent.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. The connector specifications do not define a fixed amperage rating; current capacity is determined by the wire gauge of the connected conductors and the application requirements.

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

A: Both connectors operate across a temperature range of -55°C to 105°C. Applications requiring operation outside this range require alternative connector selection.
