Key Parameters

Substitute Part Grouping Explanation

The M80-4120642 serves as a direct substitute for the M80-4120642P based on the following critical parameters:

• Identical connector type (receptacle) and contact type (female socket)
• Matching position count (6) and pitch specifications (0.079" / 2.00mm)
• Identical row configuration (2 rows with 0.079" row spacing)
• Identical mounting method (surface mount) and termination (solder)
• Matching contact finishes (gold mating, tin post) with identical thickness specifications
• Identical operating temperature range (-55°C ~ 125°C)
• Identical voltage rating (120V)
• Identical insulation material (PPS, glass filled) and color (black)
• Identical compliance certifications (ROHS3, UL94 V-0)

The primary distinction is product status: M80-4120642P is obsolete while M80-4120642 is active, with M80-4120642 available in tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The M80-4120642 is the direct active equivalent for the obsolete M80-4120642P. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, material composition, and environmental ratings.

Selection of M80-4120642 is supported by:

• Active product status ensuring ongoing availability and manufacturing support
• Identical compliance certifications (ROHS3 Compliant, UL94 V-0)
• Matching environmental specifications (operating temperature -55°C ~ 125°C, MSL 1)
• Identical contact materials and finish specifications
• Tube packaging availability for standard procurement workflows

The negligible difference in mated stacking height (7.95mm versus 7.98mm) falls within normal manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can M80-4120642 directly replace M80-4120642P in existing designs?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, contact configuration, and material specifications. The M80-4120642 is the active production equivalent.

Q: What is the significance of the product status difference?

A: M80-4120642P is obsolete, meaning Harwin Inc. no longer manufactures this part number. M80-4120642 is the active equivalent and is the recommended part for new designs and ongoing procurement.

Q: Are the mated stacking height differences significant?

A: The difference between 7.98mm and 7.95mm represents normal manufacturing variation and does not affect mechanical or electrical compatibility in standard applications.

Q: What packaging options are available?

A: M80-4120642 is supplied in tube packaging, which is standard for surface mount connectors in production environments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both M80-4120642P and M80-4120642 are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: What applications are these connectors suitable for?

A: Both parts are rated for automotive, general purpose, and military applications with a 120V voltage rating and -55°C ~ 125°C operating temperature range.
