Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M80-4024201 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Position count (42 positions)
• Mating pitch (0.079" / 2.00mm)
• Row configuration (2 rows with 0.079" spacing)
• Mounting method (Surface Mount)
• Contact configuration (Female Socket)
• Mating contact finish (Gold plating)
• Fastening mechanism (Screw Lock)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (120V)
• Flammability compliance (UL94 V-0)

The M80-4024242 meets all these criteria and qualifies as a direct substitute for the obsolete M80-4024201.

Parameter Comparison

Engineering Selection Recommendations

The M80-4024242 is the direct substitute for the obsolete M80-4024201. Both connectors share identical mechanical and electrical specifications across all critical parameters including pitch, position count, row configuration, contact type, and operating temperature range.

The primary distinction is product status: M80-4024242 is active and available, while M80-4024201 is obsolete. Additionally, M80-4024242 achieves ROHS3 compliance, whereas M80-4024201 is RoHS non-compliant. The post contact finish differs slightly (Tin versus Tin-Lead), but this does not affect mating interface compatibility or electrical performance.

For new designs or production continuity, M80-4024242 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are M80-4024201 and M80-4024242 mechanically interchangeable?

A: Yes. Both connectors feature identical 42-position, 0.079" pitch receptacle configurations with 2-row layouts, surface mount termination, and screw lock fastening. Mated stacking heights are identical at 7.7mm and 7.95mm.

Q: What is the difference in contact finish between these parts?

A: The mating contact finish (gold plating) is identical at 12.0µin (0.30µm) thickness on both parts. The post contact finish differs: M80-4024201 uses Tin-Lead while M80-4024242 uses Tin. This distinction does not affect mating interface performance.

Q: Why is M80-4024242 RoHS compliant while M80-4024201 is not?

A: M80-4024242 represents an updated version of the connector series with RoHS3 compliance. The compliance status reflects manufacturing process changes implemented after M80-4024201 was designated obsolete.

Q: Can I use M80-4024242 in applications originally designed for M80-4024201?

A: Yes. M80-4024242 maintains full electrical and mechanical compatibility with M80-4024201 across all specified parameters. The active product status of M80-4024242 makes it the recommended choice for design continuity.

Q: Are there any thermal or voltage limitations when substituting?

A: No. Both connectors operate across the identical temperature range (-55°C ~ 125°C) and voltage rating (120V). No thermal or voltage derating is required when using M80-4024242 as a substitute.
