Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-4004642 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility: Voltage rating (120V), contact material (Beryllium Copper), contact finish (Gold mating surface), and operating temperature range (-55°C ~ 125°C) must remain consistent.

Mechanical Compatibility: Pitch spacing (0.079" / 2.00mm), row configuration (2 rows), mounting type (through-hole solder termination), and fastening mechanism (screw lock) must be preserved to ensure physical and functional interchangeability.

Series Continuity: Substitute parts must belong to the Datamate J-Tek series to maintain design consistency and connector ecosystem compatibility.

The M80-4005042 qualifies as a substitute based on these parameters, with the primary difference being an increased position count (50 positions versus 46 positions) while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The M80-4005042 is the qualified substitute for the M80-4004642. Both connectors maintain identical electrical specifications, mechanical interfaces, and compliance certifications (ROHS3, REACH Unaffected, EAR99). The M80-4005042 offers the additional advantage of active product status, ensuring continued availability and supply chain support.

The primary design consideration is the position count difference: the M80-4005042 provides 50 positions compared to the 46 positions of the original part. This increased capacity does not compromise compatibility with existing mating connectors or applications designed for the 46-position configuration, as the pitch, row spacing, and mounting characteristics remain unchanged. Applications requiring exactly 46 positions may utilize the additional 4 positions for future expansion or leave them unpopulated.

Frequently Asked Questions (FAQ)

Q: Can the M80-4005042 directly replace the M80-4004642 in existing designs?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), row spacing, mounting type, and fastening mechanisms. The M80-4005042 accommodates 4 additional positions while maintaining full mechanical and electrical compatibility with mating connectors designed for the 46-position variant.

Q: What is the significance of the position count difference?

A: The M80-4005042 provides 50 contact positions versus 46 in the M80-4004642. This difference does not affect physical interchangeability or electrical performance. Designs may utilize all 50 positions, use only 46 positions, or leave additional positions unpopulated depending on application requirements.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Operating temperature range, voltage rating, and material flammability ratings (UL94 V-0) are identical.

Q: Why is the M80-4004642 obsolete while the M80-4005042 is active?

A: Product status reflects manufacturer lifecycle decisions. The M80-4005042's active status ensures ongoing availability, technical support, and supply chain continuity for new designs and production requirements.

Q: Are there packaging differences between these parts?

A: The M80-4004642 packaging is unspecified in available documentation. The M80-4005042 is supplied in bulk packaging. Confirm packaging requirements with the supplier for specific application needs.
