Key Parameters

Substitute Part Grouping Explanation

The Preci-Dip 853-83-044-20-001101 qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• 44-position configuration
• 0.050" (1.27mm) mating pitch
• 2-row layout with 0.050" (1.27mm) row spacing
• Through-hole, right-angle mounting
• Solder termination
• Push-pull fastening
• Gold contact finish on mating surface
• 1A current rating
• UL94 V-0 flammability rating
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity

The substitute maintains functional and mechanical compatibility with the original M50-3202245 across all critical interconnection parameters.

Parameter Comparison

Engineering Selection Recommendations

The Preci-Dip 853-83-044-20-001101 is suitable for applications currently using the obsolete Harwin M50-3202245. Both connectors maintain identical mating pitch, position count, row configuration, and mounting orientation. The substitute provides equivalent electrical performance at 1A current rating and maintains compliance with ROHS3 and UL94 V-0 standards.

The substitute offers an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), which provides additional thermal margin for demanding applications. The increased gold plating thickness on mating contacts (29.5µin versus 10.0µin) enhances contact durability and wear resistance.

Selection of the substitute should be based on application requirements, inventory availability, and cost considerations. Both parts are suitable for general purpose, medical, and telecommunications applications requiring 44-position rectangular connectors with 0.050" pitch and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Are the M50-3202245 and 853-83-044-20-001101 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.050"), position count (44), row spacing (0.050"), and right-angle through-hole mounting configuration. Physical dimensions and PCB footprints are compatible.

Q: What is the difference in contact finish thickness?

A: The Preci-Dip substitute features 29.5µin (0.75µm) gold plating on mating contacts compared to 10.0µin (0.25µm) on the Harwin original. Thicker plating provides extended contact life and improved wear resistance in high-cycle mating applications.

Q: Can the substitute handle the same current and temperature requirements?

A: Both connectors are rated for 1A current. The substitute supports an extended temperature range (-55°C to 125°C) compared to the original (-40°C to 105°C), making it suitable for wider environmental conditions.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the M50-3202245 and 853-83-044-20-001101 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for both parts?

A: Both connectors have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there differences in insulation material?

A: Yes. The Harwin M50-3202245 uses Polyamide (PA9T) Nylon 9T insulation, while the Preci-Dip 853-83-044-20-001101 uses Polycyclohexylenedimethylene Terephthalate (PCT) polyester with glass filling. Both materials meet UL94 V-0 flammability requirements.
