Parameter Comparison

Engineering Selection Recommendations

The M80-7542042 is the manufacturer-recommended substitute for the obsolete M80-7632042. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and procurement.

The primary distinction between these parts is product status: M80-7632042 is obsolete, while M80-7542042 is active. The M80-7542042 offers improved long-term availability and supply chain stability.

Secondary differences include connector type classification (Plug vs. Header), fastening mechanism (Friction Lock vs. Latch Holder), insulation material composition (Polyamide vs. Polyphenylene Sulfide), and voltage rating (800V vs. 120V). The contact length post dimension differs by 0.004" (0.10mm), remaining within typical tolerance ranges for board-to-board applications.

Both parts share identical pitch, row spacing, number of positions, mounting type, termination method, contact material, operating temperature range, current rating per contact, and mated stacking heights. These shared parameters establish functional compatibility for standard rectangular connector applications within the Datamate L-Tek series.

Frequently Asked Questions (FAQ)

Q: Can M80-7542042 directly replace M80-7632042 in existing designs?

A: The M80-7542042 shares critical mating parameters with M80-7632042, including pitch, row spacing, number of positions, and contact configuration. However, the connector type differs (Header vs. Plug), and the fastening mechanism changes from Friction Lock to Latch Holder. Board layout and mechanical mounting considerations must be evaluated for each application.

Q: What is the significance of the voltage rating difference?

A: M80-7632042 carries an 800V voltage rating, while M80-7542042 is rated for 120V. Applications requiring voltages above 120V must retain the original M80-7632042 specification or identify alternative substitutes rated for higher voltages.

Q: How does the insulation material change affect performance?

A: M80-7632042 uses Polyamide (PA46), Nylon 4/6 insulation, while M80-7542042 uses Polyphenylene Sulfide (PPS), Glass Filled insulation. Both materials maintain UL94 V-0 flammability rating and support the identical operating temperature range of -55°C to 125°C. Material selection depends on specific environmental and mechanical requirements of the application.

Q: Are there packaging differences between these parts?

A: M80-7632042 packaging is not specified in the provided data. M80-7542042 is supplied in Tube packaging. Packaging format may affect procurement, handling, and assembly processes.

Q: What is the contact length post dimension difference?

A: M80-7632042 has a contact length post of 0.181" (4.60mm), while M80-7542042 measures 0.177" (4.50mm). This 0.004" (0.10mm) difference is minimal and typically accommodated within standard PCB design tolerances for through-hole solder connections.

Q: Why is M80-7632042 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The M80-7542042 serves as the active replacement within the Datamate L-Tek series, ensuring continued availability and support for new designs and production runs.
