Key Parameters

Substitute Part Grouping Explanation

The M80-4101242 qualifies as a direct substitute for the M80-4101201 based on matching electrical and mechanical parameters. Substitution compatibility is determined by the following critical parameters:

• Connector type, contact type, and style (Receptacle, Female Socket, Board to Board or Cable)
• Position count and arrangement (12 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting and termination method (Through Hole, Solder)
• Mating contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (120V)
• Insulation material and flammability rating (PPS Glass Filled, UL94 V-0)

The M80-4101242 maintains identical specifications across all these parameters, enabling direct functional replacement in applications currently using the M80-4101201.

Parameter Comparison

Engineering Selection Recommendations

The M80-4101242 is the active production equivalent for the obsolete M80-4101201. Both connectors are functionally identical across all electrical and mechanical parameters critical to connector selection. The primary distinction is product status: M80-4101201 is obsolete while M80-4101242 is active.

For new designs or ongoing production requiring this connector type, M80-4101242 should be specified. The substitute part maintains full compatibility with existing mating interfaces and PCB layouts designed for the original M80-4101201.

An additional consideration is regulatory compliance: M80-4101242 carries ROHS3 compliance status, whereas M80-4101201 is RoHS non-compliant. Post contact finish differs slightly (Tin versus Tin-Lead), though both maintain identical contact finish thickness specifications.

Frequently Asked Questions (FAQ)

Q: Can M80-4101242 directly replace M80-4101201 in existing assemblies?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (12), row configuration (2 rows), mounting type (through hole), and contact geometry. PCB layouts and mating connectors designed for M80-4101201 are fully compatible with M80-4101242.

Q: What is the primary reason for substitution?

A: M80-4101201 is obsolete. M80-4101242 is the active production part from the same manufacturer and series, maintaining identical electrical and mechanical specifications.

Q: Are there packaging differences between these parts?

A: M80-4101201 packaging is not specified in available data. M80-4101242 is supplied in tube packaging. Confirm packaging requirements for your application.

Q: Does the post contact finish change affect performance?

A: Both M80-4101201 (Tin-Lead) and M80-4101242 (Tin) maintain identical contact finish thickness (137.8µin / 4.60µm) on the post. The functional performance difference is negligible for standard applications.

Q: What is the RoHS compliance difference?

A: M80-4101201 is RoHS non-compliant. M80-4101242 is ROHS3 compliant. If your application or region requires RoHS compliance, M80-4101242 is the appropriate selection.

Q: Are these connectors suitable for automotive applications?

A: Yes. Both parts list automotive applications and maintain UL94 V-0 flammability rating with operating temperature range of -55°C to 125°C, supporting automotive environmental requirements.
