M80-4202201 Equivalent & Substitute Parts Reference

Part Overview

The M80-4202201 is a 22-position receptacle connector from Harwin Inc.'s Datamate J-Tek series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. This connector features through-hole solder termination, screw lock fastening, and gold-plated mating contacts rated for -55°C to 125°C operation. The product is currently obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M80-4202201 is determined by the following critical parameters:

• Connector Series & Manufacturer: Must be Datamate J-Tek from Harwin Inc. to ensure mechanical and electrical compatibility
• Pitch Specification: 0.079" (2.00mm) mating pitch is mandatory for proper mating interface alignment
• Mounting Configuration: Through-hole solder termination with screw lock fastening must be maintained
• Electrical Ratings: Operating temperature range of -55°C to 125°C and 120V voltage rating establish baseline performance requirements
• Contact Configuration: Female socket contacts with gold mating finish and beryllium copper material ensure signal integrity

The M80-4202442 qualifies as a manufacturer-recommended substitute. While it increases position count from 22 to 24, it maintains all critical electrical, mechanical, and thermal parameters within the allowed specification envelope for this connector category. The position increase does not compromise compatibility with existing mating interfaces, as the additional contacts extend the connector footprint without altering the core pitch or row spacing geometry.

Parameter Comparison

Engineering Selection Recommendations

The M80-4202442 is the manufacturer-recommended substitute for the obsolete M80-4202201. Selection of this substitute is supported by the following factors:

• Product Status: The M80-4202442 maintains active product status with Harwin Inc., ensuring continued availability and manufacturing support
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements
• Certification Alignment: Both connectors carry UL94 V-0 flammability rating and identical electrical certifications, maintaining system-level compliance requirements
• Mechanical & Electrical Equivalence: All critical parameters including pitch, row spacing, operating temperature range, voltage rating, and contact materials are identical between the two parts

The position count increase from 22 to 24 does not introduce compatibility issues when the mating connector is designed to accommodate the extended footprint or when unused positions are left unloaded.

Frequently Asked Questions (FAQ)

Q: Can the M80-4202442 directly replace the M80-4202201 in existing designs?

A: The M80-4202442 is mechanically and electrically compatible with the M80-4202201 when the mating interface is designed to accept the 24-position configuration. The identical pitch, row spacing, and mounting characteristics ensure proper alignment and connection. If the existing mating connector is fixed at 22 positions, physical interference may occur.

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

A: The M80-4202442 provides two additional contact positions (24 total versus 22), extending the connector footprint while maintaining all other electrical and mechanical specifications. This allows for expanded signal routing capacity within the same connector family.

Q: Are the contact finishes identical between the two parts?

A: The mating contact finish is identical: gold plating at 12.0µin (0.30µm) thickness. The post contact finish differs slightly: the M80-4202201 uses tin-lead, while the M80-4202442 uses tin. Both finishes are compatible with standard solder termination processes.

Q: Does the position count increase affect thermal or electrical performance?

A: No. The operating temperature range (-55°C to 125°C), voltage rating (120V), and electrical characteristics remain unchanged. The additional positions do not degrade performance of existing circuits.

Q: What is the inventory status of these parts?

A: The M80-4202201 is obsolete with 685 pieces available as new original stock. The M80-4202442 is active with 820 pieces in current inventory, ensuring long-term availability for new designs and production requirements.
