• Series: Datamate J-Tek
• Connector Type: Receptacle
• Contact Type: Female Socket
• Pitch: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing: 0.079" (2.00mm)
• Cable Termination: Crimp
• Wire Gauge: 22 AWG
• Contact Finish: Gold
• Contact Finish Thickness: 11.8µin (0.30µm)
• Features: Jackscrews, Polarizing Key
• Color: Black

Variable Parameter:

• Number of Positions: The substitute part M80-4605005 contains 50 positions compared to the original 46 positions. This represents a higher-capacity variant within the same connector family, maintaining all other electrical and mechanical specifications.

The M80-4605005 qualifies as a substitute because it preserves all core compatibility parameters while offering increased contact density. The substitute part is currently in active production status, ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The M80-4605005 is the designated manufacturer-recommended substitute for the obsolete M80-4604642. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, row configuration, contact finish, and termination method.

The primary distinction is the increased position count in the substitute part (50 versus 46 positions). This higher-capacity variant is suitable for applications requiring additional contact channels while maintaining compatibility with the Datamate J-Tek connector family specifications.

Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The substitute part's active production status provides assured long-term availability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the M80-4605005 directly replace the M80-4604642 in existing applications?

A: The M80-4605005 maintains all core electrical and mechanical specifications of the M80-4604642, including pitch, row spacing, contact finish, and termination method. The 50-position configuration accommodates the original 46-position requirement. Physical envelope and mating interface compatibility are preserved within the Datamate J-Tek series.

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

A: The M80-4605005 provides four additional contact positions (50 versus 46). This represents a higher-capacity variant of the same connector family. Applications utilizing fewer than 50 positions can use the substitute part with unused positions remaining unoccupied.

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

A: Both parts carry identical ROHS3 compliance status and moisture sensitivity level ratings (MSL 1 - Unlimited). No compliance or certification differences exist between the main part and substitute.

Q: Why is the original part listed as obsolete?

A: The M80-4604642 is classified as obsolete by the manufacturer. The M80-4605005 represents the current active production alternative within the Datamate J-Tek series, ensuring ongoing component availability and support.

Q: Are the crimp termination specifications identical?

A: Both parts utilize crimp cable termination with 22 AWG discrete wire gauge and identical gold contact finish specifications (11.8µin / 0.30µm thickness). Crimp tooling and termination procedures remain consistent between the parts.
