• Mounting Method: Both utilize through-hole solder termination with identical fastening type (locking ramp)
• Contact Interface: Both feature gold-plated mating contacts with circular contact geometry and beryllium copper material
• Insulation Specifications: Both maintain identical insulation height (0.202" / 5.14mm) and black insulation color
• Environmental Rating: Both support -55°C to 125°C operating temperature range with UL94 V-0 flammability compliance
• Series Compatibility: Both belong to the Datamate L-Tek series, ensuring mechanical and electrical interchangeability

The M80-8400242 represents an active production alternative with enhanced specifications and improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The M80-8400242 is the designated substitute for the obsolete M80-8940201. Selection of the M80-8400242 provides the following advantages:

Product Status: The M80-8400242 maintains active production status with 867 units in current inventory, ensuring reliable long-term component availability compared to the obsolete M80-8940201.

Regulatory Compliance: The M80-8400242 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The M80-8940201 is RoHS non-compliant and does not satisfy modern procurement standards.

Electrical Performance: The M80-8400242 provides enhanced voltage rating (800V versus 120V), delivering superior electrical performance margin for applications requiring higher voltage tolerance.

Material Specification: The M80-8400242 utilizes polyamide (PA46) nylon 4/6 glass-filled insulation material, replacing the polyester glass-filled insulation of the M80-8940201, providing improved thermal and mechanical properties.

Contact Post Specifications: The M80-8400242 features extended contact post length (0.126" / 3.20mm versus 0.051" / 1.30mm), accommodating thicker PCB assemblies and improving solder joint reliability.

Frequently Asked Questions (FAQ)

Q: Are M80-8940201 and M80-8400242 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), mounting type (through-hole), insulation height (0.202" / 5.14mm), and fastening mechanism (locking ramp). They are members of the same Datamate L-Tek series and maintain full mechanical compatibility.

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

A: The M80-8400242 is the active production equivalent of the obsolete M80-8940201. Key differences include product status (active versus obsolete), RoHS compliance (ROHS3 versus non-compliant), voltage rating (800V versus 120V), contact post length (0.126" versus 0.051"), and insulation material composition (polyamide versus polyester).

Q: Can the M80-8400242 be used in applications originally designed for the M80-8940201?

A: Yes. The M80-8400242 meets or exceeds all critical electrical and mechanical parameters of the M80-8940201, including operating temperature range (-55°C to 125°C), contact material (beryllium copper), mating contact finish (gold), and flammability rating (UL94 V-0). The enhanced specifications of the M80-8400242 provide improved performance margins.

Q: What packaging format is supplied for each part?

A: The M80-8940201 is supplied in bulk packaging. The M80-8400242 is supplied in tube packaging, which provides improved component protection and handling efficiency for production environments.

Q: Are there any post-plating differences that affect solderability?

A: The M80-8940201 features tin-lead post plating (157.5µin / 4.00µm thickness). The M80-8400242 features tin post plating (137.8µin / 3.50µm thickness). Both finishes are compatible with standard solder reflow processes. The tin plating of the M80-8400242 aligns with lead-free manufacturing requirements.
