M80-4000000FD-04-321-00-000 Equivalent & Substitute Parts

Part Overview

The M80-4000000FD-04-321-00-000 is a 4-position receptacle connector from Harwin Inc.'s Datamate Mix-Tek series, designed for board-to-board or cable applications. This connector features a 0.157" (4.00mm) pitch, through-hole solder termination, and gold-plated contacts rated for 20A at 800V. The product is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the M80-4000000FD-04-321-00-000 is determined by the following critical parameters:

• Series Compatibility: Substitute parts must belong to the Datamate Mix-Tek series to ensure mechanical and electrical compatibility
• Connector Type: Receptacle configuration must be maintained
• Pitch Specification: 0.157" (4.00mm) mating pitch is required for proper mating with existing plug connectors
• Mounting and Termination: Through-hole solder termination must be preserved
• Electrical Ratings: Current (20A) and voltage (800V) ratings must be met or exceeded
• Operating Temperature Range: -55°C ~ 125°C specification must be maintained
• Contact Configuration: Female socket, power contacts with gold plating

The M80-4000000FD-06-321-00-000 qualifies as a substitute based on these parameters, with the primary difference being an increased position count (6 positions versus 4 positions).

Parameter Comparison

Engineering Selection Recommendations

The M80-4000000FD-06-321-00-000 is available as an active product from Harwin Inc., whereas the original M80-4000000FD-04-321-00-000 is obsolete. Both connectors maintain identical electrical ratings (20A, 800V), operating temperature range (-55°C ~ 125°C), and mechanical specifications including pitch, mounting type, and termination method. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is the position count: the substitute provides 6 positions instead of 4. This increased capacity allows for expanded connectivity while maintaining full backward compatibility with the Datamate Mix-Tek series mating interface. The active product status of the M80-4000000FD-06-321-00-000 ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the M80-4000000FD-06-321-00-000 directly replace the M80-4000000FD-04-321-00-000?

A: The M80-4000000FD-06-321-00-000 is mechanically and electrically compatible with the same mating plug connectors due to identical pitch (0.157"), mounting type, and fastening mechanism. The 6-position configuration accommodates the 4-position requirement with additional available positions.

Q: What is the primary reason for substitution?

A: The original M80-4000000FD-04-321-00-000 is obsolete. The M80-4000000FD-06-321-00-000 provides an active, currently manufactured alternative within the same Datamate Mix-Tek series.

Q: Are the electrical and thermal specifications identical?

A: Yes. Both connectors are rated for 20A at 800V and operate across the same temperature range of -55°C ~ 125°C. Both meet UL94 V-0 flammability requirements.

Q: Does the increased position count affect PCB layout?

A: The connector footprint will be slightly larger due to the additional 2 positions at the same 0.157" pitch. PCB layout modifications may be required to accommodate the increased connector length.

Q: Are compliance certifications maintained?

A: Yes. Both connectors are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.
