Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M50-3201745 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 34
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole, Right Angle
• Connector Type: Receptacle
• Contact Type: Female Socket
• Termination: Solder
• Fastening Type: Push-Pull

Secondary Compatibility Factors:

• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• Insulation Material: Polyamide (PA9T), Nylon 9T

Two substitute parts are identified:

1. M50-3200945 (Harwin Inc.) - Same series alternative with reduced position count (18 positions). Shares identical pitch, row spacing, mounting configuration, and contact specifications. Active product status with ROHS3 compliance.

2. 853-43-034-20-001000 (Mill-Max Manufacturing Corp.) - Cross-manufacturer equivalent with matching 34-position configuration, pitch, and mounting type. Maintains identical connector geometry and electrical interface. Active product status with enhanced current rating (3A) and extended operating temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

M50-3200945 (Harwin Inc.) is suitable for applications requiring a reduced connector footprint with 18 positions while maintaining identical electrical and mechanical interface specifications. This part is active and ROHS3 compliant, making it appropriate for new designs subject to RoHS regulations. Position count reduction necessitates circuit redesign.

853-43-034-20-001000 (Mill-Max Manufacturing Corp.) provides direct 34-position equivalence with identical connector geometry and pin configuration. This part maintains active product status and offers enhanced electrical performance through increased current rating (3A) and extended operating temperature range (-55°C ~ 125°C). However, RoHS non-compliance status must be evaluated against application regulatory requirements. The thicker gold plating (30.0µin versus 10.0µin) and beryllium copper contact material provide enhanced durability for high-cycle mating applications.

For applications requiring RoHS3 compliance, M50-3200945 is the appropriate selection if position count reduction is acceptable. For applications requiring full 34-position equivalence with enhanced electrical performance and RoHS compliance is not mandated, 853-43-034-20-001000 is the direct substitute.

Frequently Asked Questions (FAQ)

Q: Can M50-3200945 be used as a direct replacement for M50-3201745?

A: M50-3200945 shares identical pitch (0.050"), row spacing, mounting type, and contact specifications. However, it provides only 18 positions versus 34 positions in the original part. Direct substitution requires circuit redesign to accommodate the reduced pin count.

Q: What are the key differences between 853-43-034-20-001000 and M50-3201745?

A: Both parts maintain 34-position configuration, 0.050" pitch, and through-hole right-angle mounting. Differences include: contact material (beryllium copper versus phosphor bronze), contact shape (circular versus square), insulation material (PCT polyester versus PA9T nylon), contact finish thickness (30.0µin versus 10.0µin), current rating (3A versus 1A), operating temperature range (-55°C to 125°C versus -40°C to 105°C), and RoHS compliance status (non-compliant versus ROHS3 compliant).

Q: Is 853-43-034-20-001000 electrically compatible with M50-3201745?

A: Both connectors maintain identical mating pitch, row spacing, and push-pull fastening configuration. Electrical compatibility is established through matching connector geometry and contact interface specifications. The higher current rating (3A) of 853-43-034-20-001000 provides enhanced capacity for the same 1A application requirement.

Q: What packaging options are available for substitute parts?

A: M50-3200945 is supplied in tube packaging. 853-43-034-20-001000 is supplied in bulk packaging. Packaging selection should align with procurement and assembly process requirements.

Q: Why is 853-43-034-20-001000 marked as RoHS non-compliant?

A: RoHS non-compliance status is provided as specified in the part data. Applications subject to RoHS regulations must select ROHS3 compliant alternatives such as M50-3200945 or confirm regulatory exemptions for the application.
