• IDC cable termination method
• Gold contact finish with 30.0µin thickness

Mechanical Parameters:

• Female socket contact type
• Receptacle connector classification
• Free-hanging and right-angle mounting capability
• Locking ramp fastening mechanism
• Closed-end design
• White color
• MTA-100 series designation

Environmental & Compliance Parameters:

• Moisture Sensitivity Level 1 rating
• ECCN and HTSUS classifications

The substitute part 4-644020-0 satisfies all equivalence criteria and is classified as a direct manufacturer substitute within the MTA-100 rectangular connector family.

Parameter Comparison

Engineering Selection Recommendations

The 4-644020-0 is the direct equivalent substitute for the obsolete 1-644020-0. Both parts share identical electrical and mechanical specifications within the MTA-100 rectangular connector series.

Primary Selection Basis:

The 4-644020-0 is recommended for component selection due to its active product status. The 1-644020-0 is classified as obsolete and subject to discontinuation, making it unsuitable for new designs or long-term production planning.

Compliance Advantage:

The 4-644020-0 carries RoHS Compliant certification, whereas the 1-644020-0 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements in the European Union and equivalent jurisdictions.

Inventory & Availability:

The 4-644020-0 is available in bulk packaging with 1017 pieces in stock, compared to 621 pieces of the obsolete variant. The active status ensures continued availability for production and replacement requirements.

Functional Interchangeability:

All electrical and mechanical parameters are identical between the two parts. The 4-644020-0 operates identically to the 1-644020-0 in IDC termination, contact resistance, mating cycles, and environmental performance. No circuit redesign or connector interface modification is required for substitution.
