Substitute Part Grouping Explanation

Substitution eligibility for the M50-3200745 is determined by strict alignment with the following critical parameters:

  • Connector Type & Contact Type: Must be Receptacle with Female Socket contacts
  • Pitch Specification: Mating pitch must be 0.050" (1.27mm)
  • Row Configuration: Must maintain 2 rows with 0.050" (1.27mm) row spacing
  • Mounting & Termination: Through-hole, right-angle mounting with solder termination required
  • Contact Finish: Gold plating on mating surfaces
  • Electrical Rating: 1A current rating minimum
  • Temperature Range: Operating range of -40°C ~ 105°C
  • Series Compatibility: Archer M50 series maintains mechanical and electrical interchangeability

The M50-3200845 qualifies as a manufacturer-recommended substitute based on these parameters. The primary difference is position count (16 vs. 14), which represents a higher-capacity variant within the same connector family while maintaining all critical mechanical and electrical specifications.

Engineering Selection Recommendations

The M50-3200845 is the manufacturer-recommended substitute for the obsolete M50-3200745. Both components maintain identical mechanical interfaces, electrical ratings, and environmental specifications. The M50-3200845 offers the advantage of active product status, ensuring continued availability and manufacturing support.

Selection of the M50-3200845 is appropriate for applications requiring the same connector footprint and electrical performance. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The identical operating temperature range (-40°C ~ 105°C), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1) ensure compatibility in equivalent application environments.

The primary design consideration is the increased position count (16 vs. 14). Applications utilizing fewer than 14 positions can accommodate the M50-3200845 with unused contact positions. Applications requiring exactly 14 positions must evaluate whether the additional 2 contact positions present mechanical or electrical constraints within the specific system design.

Frequently Asked Questions (FAQ)

Q: Can the M50-3200845 directly replace the M50-3200745 in existing designs?

A: The M50-3200845 maintains identical pitch (0.050"), row spacing (0.050"), mounting type (through-hole right-angle), and contact specifications. Direct mechanical and electrical substitution is possible. Design verification is required only if the additional 2 contact positions create space constraints or if the application uses a mated connector with exactly 14 positions.

Q: What is the primary difference between these two connectors?

A: The M50-3200745 provides 14 contact positions while the M50-3200845 provides 16 contact positions. All other mechanical, electrical, and environmental specifications are identical.

Q: Are both connectors compatible with the same mating connectors?

A: Both connectors are part of the Archer M50 series with identical pitch and row spacing. Mating compatibility depends on the specific mating connector design. A mating connector designed for 14 positions will not fully utilize the M50-3200845's 16 positions, but mechanical mating will occur. A mating connector designed for 16 positions will not mate with the M50-3200745.

Q: What is the significance of the M50-3200745 being obsolete?

A: Obsolete status indicates the manufacturer no longer produces this part. The M50-3200845 is the active equivalent, ensuring continued supply chain availability and manufacturing support for new procurements and production runs.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability. Both maintain MSL 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements.

Q: What packaging is available for the M50-3200845?

A: The M50-3200845 is supplied in tube packaging, as specified by the manufacturer.
