Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors is determined by strict alignment of electrical and mechanical parameters. The M80-4002801 can be substituted by components that maintain compatibility across the following critical parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Pitch spacing (0.079" / 2.00mm mating pitch)
Row configuration (2 rows with 0.079" row spacing)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Screw Lock)
Contact finish on mating surface (Gold)
Operating temperature range (-55°C ~ 125°C)
Voltage rating (120V minimum)
Insulation material (Polyphenylene Sulfide, Glass Filled)
Compliance certifications (UL94 V-0, ROHS3)

The M80-4003442 qualifies as a substitute based on these parameters. The primary difference is the number of positions (34 vs. 28), which represents an increase in contact capacity while maintaining all other electrical and mechanical specifications.

Engineering Selection Recommendations

The M80-4003442 is the designated substitute for the obsolete M80-4002801. Both components are manufactured by Harwin Inc. within the Datamate J-Tek series and share identical electrical and mechanical specifications with the exception of position count.

The M80-4003442 offers the advantage of active product status, ensuring ongoing availability and manufacturing support. All compliance certifications remain equivalent, including ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. The contact finish specifications, operating temperature range, and voltage ratings are maintained.

The primary design consideration is the increased number of positions (34 vs. 28). Applications requiring exactly 28 positions must account for the additional 6 contact positions in the M80-4003442. PCB layout and connector footprint modifications may be necessary to accommodate the larger connector body.

Frequently Asked Questions (FAQ)

Q: Can the M80-4003442 be used as a direct replacement for the M80-4002801?

A: The M80-4003442 is electrically and mechanically compatible with the M80-4002801 across all critical parameters. However, the increased position count (34 vs. 28) requires PCB layout modifications. Direct pin-for-pin substitution is not possible without design changes.

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

A: The M80-4003442 provides 34 contact positions compared to the M80-4002801's 28 positions. All other specifications, including pitch, row spacing, mounting type, termination method, and fastening mechanism, remain identical.

Q: Are the compliance certifications the same?

A: Both connectors maintain ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. Compliance certifications are equivalent.

Q: What is the significance of the product status difference?

A: The M80-4002801 is obsolete, indicating discontinued manufacturing and limited availability. The M80-4003442 is active, ensuring continued manufacturing support and reliable supply chain access.

Q: Are the contact finishes compatible?

A: Both connectors feature gold-plated mating contacts with identical finish thickness (12.0µin / 0.30µm). The post contact finish differs slightly (Tin-Lead vs. Tin), but this does not affect substitution compatibility.

Q: What packaging format is available for the M80-4003442?

A: The M80-4003442 is supplied in tube packaging, compared to the M80-4002801 which had no specified packaging format.
