Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-4124201P is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration: Receptacle with female socket contacts
• Electrical specifications: 42 positions, 0.079" (2.00mm) mating pitch, 2-row configuration
• Physical form factor: Surface mount termination with solder attachment
• Environmental ratings: -55°C to 125°C operating range, UL94 V-0 flammability compliance
• Mating interface: Gold-plated contacts for reliable signal transmission
• Series compatibility: Datamate J-Tek platform

The M80-4124242 qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status transition from obsolete to active, enabling continued procurement and design implementation.

Parameter Comparison

Engineering Selection Recommendations

The M80-4124242 is the direct functional equivalent for applications currently utilizing the M80-4124201P. Selection of the M80-4124242 is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance meeting current regulatory requirements for electronic components
• Identical electrical and mechanical specifications across all critical connector parameters
• Maintained compatibility within the Datamate J-Tek series platform
• Equivalent environmental ratings and certifications (UL94 V-0, REACH Unaffected, EAR99)

The transition from tin-lead to tin post plating on the M80-4124242 reflects industry-standard lead-free manufacturing practices and does not impact functional compatibility or performance in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the M80-4124242 be used as a direct replacement for the M80-4124201P?

A: Yes. Both connectors share identical specifications for connector type, contact configuration, position count, mating pitch, mounting method, and environmental ratings. The M80-4124242 is the active equivalent component.

Q: What is the difference between the post plating on these two connectors?

A: The M80-4124201P uses tin-lead plating on the posts, while the M80-4124242 uses tin plating. Both meet the specified contact finish thickness of 137.8µin (4.60µm) and are functionally equivalent for solder termination applications.

Q: Are there packaging differences between these parts?

A: The M80-4124201P packaging is not specified in the available data. The M80-4124242 is supplied in tube packaging. Packaging format does not affect connector functionality or compatibility.

Q: Does the M80-4124242 meet current regulatory standards?

A: Yes. The M80-4124242 is ROHS3 compliant and maintains REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the mated stacking height difference?

A: The mated stacking heights differ slightly (7.98mm for M80-4124201P versus 7.95mm for M80-4124242). This 0.03mm variation is within normal manufacturing tolerance and does not impact mechanical or electrical compatibility in standard board-to-board applications.

Q: Are both connectors suitable for automotive and military applications?

A: Yes. Both the M80-4124201P and M80-4124242 are rated for automotive, general purpose, and military applications with identical operating temperature ranges (-55°C to 125°C) and UL94 V-0 flammability certification.
