Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-644487-0 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (10)
• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)

Electrical Compatibility:

• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Copper Alloy)
• Contact finish on mating surface (Gold)

Regulatory Compliance:

• RoHS3 compliance
• UL94 V-0 flammability rating
• REACH unaffected status

The substitute part 3-644487-0 maintains full equivalence across all specified parameters, with the primary distinction being product status (active versus obsolete) and packaging configuration (bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-644487-0 is the direct equivalent substitute for the obsolete 1-644487-0 part number. Both components are manufactured by TE Connectivity within the MTA-100 series and maintain identical electrical, mechanical, and dimensional specifications.

Primary Substitution Basis:

The 3-644487-0 maintains active product status, ensuring continued availability and manufacturing support. This part carries identical RoHS3 compliance and UL94 V-0 flammability certification, meeting all regulatory requirements of the original component. The connector specifications—including 10-position, single-row configuration, 0.100" pitch, through-hole mounting, shrouded 4-wall design, and solder termination—are fully preserved.

Contact Finish Consideration:

The substitute part features tin-only post finish compared to the tin-lead finish of the original part. This change reflects industry-wide transition to lead-free manufacturing practices and does not affect functional compatibility or electrical performance in solder joint formation.

Compliance Status:

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical ratings (250VAC, -55°C to 105°C operating range). The moisture sensitivity level remains at MSL 1 (unlimited), indicating no special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-644487-0 be used as a direct replacement for the 1-644487-0 in existing designs?

A: Yes. The 3-644487-0 is electrically and mechanically equivalent to the 1-644487-0 across all specified parameters. Both components share identical connector type, position count, pitch spacing, mounting method, shrouding configuration, and electrical ratings. The parts are interchangeable in board-to-cable/wire applications.

Q: What is the difference between the tin-lead finish on the original part and the tin finish on the substitute?

A: The contact finish difference reflects manufacturing process updates. The tin finish on the 3-644487-0 provides equivalent solder joint reliability and electrical performance. Both finishes are compatible with standard solder reflow and wave soldering processes.

Q: Are there any packaging differences between the two part numbers?

A: The 1-644487-0 is listed with standard packaging, while the 3-644487-0 is supplied in bulk packaging. This distinction affects order quantities and handling but does not alter component specifications or performance characteristics.

Q: Does the substitute part maintain the same regulatory certifications?

A: Yes. The 3-644487-0 carries identical RoHS3 compliance, UL94 V-0 flammability rating, REACH unaffected status, and ECCN/HTSUS classifications as the original 1-644487-0.

Q: What is the current availability status of these parts?

A: The 1-644487-0 is classified as obsolete. The 3-644487-0 is an active product with current manufacturing support and documented inventory availability, making it the appropriate selection for new designs and ongoing production requirements.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts maintain identical contact lengths (mating: 0.200", post: 0.140", overall: 0.440"), insulation height (0.410"), and board guide features. PCB footprints and mounting hole patterns are identical.

Q: Can the 3-644487-0 be used in applications requiring the full -55°C to 105°C operating temperature range?

A: Yes. The substitute part is rated for the identical operating temperature range of -55°C to 105°C and maintains all electrical specifications across this range.
