Substitute Part Grouping Explanation

Substitution eligibility for the M50-3201845 is determined by the following critical parameters:

Connector Type & Contact Type: Receptacle with female socket contacts
Number of Positions: 36 positions
Pitch - Mating: 0.050" (1.27mm)
Number of Rows: 2 rows
Row Spacing - Mating: 0.050" (1.27mm)
Mounting Type: Through hole, right angle
Termination: Solder
Contact Finish - Mating: Gold
Current Rating: 1A
Fastening Type: Push-Pull

Two substitute parts meet these criteria:

M50-3200945 (Harwin Inc.) - Partial substitute with reduced position count (18 positions instead of 36). Maintains identical pitch, row spacing, mounting type, termination, contact finish, and current rating. Active product status.

853-83-036-20-001101 (Preci-Dip) - Full position count match (36 positions). Maintains identical pitch, row spacing, mounting type, termination, current rating, and fastening type. Active product status with extended operating temperature range.

Engineering Selection Recommendations

853-83-036-20-001101 (Preci-Dip) is the primary substitute for direct replacement applications. This part maintains full position count (36), identical pitch and row spacing, and all critical electrical and mechanical parameters. Both parts are ROHS3 compliant with UL94 V-0 flammability rating. The Preci-Dip part offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin for demanding applications. Active product status ensures ongoing availability.

M50-3200945 (Harwin Inc.) is applicable only for applications requiring 18 positions or fewer. This part shares the same manufacturer (Harwin Inc.) and series characteristics, maintaining identical pitch, row spacing, mounting configuration, and electrical ratings. Active product status supports long-term procurement. This substitute is suitable for designs that can accommodate the reduced position count.

Frequently Asked Questions (FAQ)

Q: Can M50-3200945 be used as a direct replacement for M50-3201845?

A: M50-3200945 is not a direct replacement due to position count mismatch (18 versus 36 positions). It is suitable only for applications requiring 18 or fewer positions. For full 36-position functionality, use 853-83-036-20-001101.

Q: What are the key compatibility criteria for these substitutes?

A: Compatibility is determined by matching pitch (0.050"), row spacing (0.050"), mounting type (through hole right angle), termination method (solder), contact finish (gold), and current rating (1A). Both substitutes meet these criteria.

Q: Does the Preci-Dip 853-83-036-20-001101 differ from the original M50-3201845?

A: The Preci-Dip part maintains all critical electrical and mechanical parameters. Differences include extended operating temperature range (-55°C ~ 125°C), different contact material (beryllium copper versus phosphor bronze), and different insulation material (PCT polyester versus polyamide). These differences do not affect functional compatibility for standard applications.

Q: Are both substitutes RoHS compliant?

A: Yes. Both M50-3200945 and 853-83-036-20-001101 are ROHS3 compliant with UL94 V-0 flammability rating, matching the original part's compliance status.

Q: What is the packaging difference between the substitutes?

A: M50-3200945 is supplied in tube packaging. 853-83-036-20-001101 is supplied in bulk packaging. Packaging does not affect electrical or mechanical compatibility.
