Key Parameters

Substitute Part Grouping Explanation

The M80-8501442 qualifies as a direct substitute for the M80-8911401 based on the following critical parameters:

• Connector Type & Position Count: Both are 14-position receptacles within the Datamate L-Tek series
• Pitch & Row Configuration: Identical 0.079" (2.00mm) mating pitch and 2-row layout
• Mounting & Termination: Both use through-hole solder termination
• Contact Finish - Mating: Both feature gold-plated mating contacts
• Operating Temperature: Identical -55°C ~ 125°C range
• Material Flammability: Both meet UL94 V-0 rating
• Contact Shape & Material: Both use circular beryllium copper contacts

The M80-8501442 represents the active production equivalent, with the primary differences being post contact finish (tin vs. tin-lead), voltage rating increase (800V vs. 120V), insulation material variation (polyamide vs. polyester), and improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The M80-8501442 is the active production equivalent for the obsolete M80-8911401. Selection of the substitute part is based on the following factors:

Product Status: The M80-8911401 is obsolete, while M80-8501442 is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The M80-8501442 achieves ROHS3 compliance, whereas the M80-8911401 is non-compliant. This distinction is critical for applications subject to RoHS regulations in automotive, industrial, and consumer electronics markets.

Electrical Performance: The M80-8501442 provides an increased voltage rating of 800V compared to 120V in the M80-8911401, offering enhanced electrical margin for demanding applications.

Contact Post Geometry: The M80-8501442 features a longer contact post (0.118" vs. 0.051"), which may require PCB layout adjustment but provides improved mechanical engagement and solder joint reliability.

Insulation Material: The M80-8501442 uses polyamide (PA46) nylon 4/6 glass-filled insulation versus polyester in the original part, offering improved thermal and mechanical properties.

Post Finish: The M80-8501442 uses tin finish instead of tin-lead, aligning with lead-free manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can M80-8501442 directly replace M80-8911401 in existing designs?

A: The M80-8501442 is mechanically and electrically compatible for mating interface purposes. However, the longer contact post (0.118" vs. 0.051") requires PCB hole depth verification. Existing PCB layouts designed for the shorter post may require modification to accommodate the longer post geometry.

Q: What is the significance of the voltage rating difference (120V vs. 800V)?

A: The voltage rating indicates the maximum voltage the connector can safely withstand. The M80-8501442's 800V rating provides greater electrical margin and makes it suitable for a broader range of applications. This is not a limitation for applications operating at or below 120V.

Q: Why is RoHS3 compliance important for the M80-8501442?

A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements, the M80-8501442 is the compliant choice, whereas the M80-8911401 is non-compliant.

Q: Are there packaging differences between these parts?

A: The M80-8501442 is supplied in tube packaging, while the M80-8911401 packaging is not specified. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts share the same mating interface?

A: Yes. Both parts maintain identical 0.079" (2.00mm) pitch, 2-row configuration, and locking ramp fastening, ensuring mechanical compatibility with mating connectors designed for the Datamate L-Tek series.

Q: What is the impact of insulation material change from polyester to polyamide?

A: Polyamide (PA46) nylon 4/6 offers superior thermal stability, moisture resistance, and mechanical strength compared to polyester. This material change enhances connector durability in automotive and industrial environments.
