Substitute Part Grouping Explanation

Substitution eligibility for the M80-4012001 is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle)
Position count (20 positions)
Mating pitch (0.079" / 2.00mm)
Row configuration (2 rows with 0.079" spacing)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Screw Lock)
Contact finish at mating interface (Gold)
Operating temperature range (-55°C ~ 125°C)
Voltage rating (120V)
Flammability compliance (UL94 V-0)

The M80-4012042 meets all substitution criteria as an active product within the same Datamate J-Tek series, maintaining identical mechanical and electrical specifications while offering improved compliance status.

Engineering Selection Recommendations

The M80-4012042 is the direct substitute for the obsolete M80-4012001. Both connectors maintain identical mechanical and electrical specifications across all critical parameters, ensuring direct compatibility in existing designs and applications.

The primary distinction between the two parts is product status and regulatory compliance. The M80-4012001 is obsolete and RoHS non-compliant, while the M80-4012042 is an active product with ROHS3 compliance. For new designs or systems requiring regulatory compliance with current environmental standards, the M80-4012042 is the appropriate selection. For legacy system maintenance where the original part is no longer available, the M80-4012042 provides functional equivalence without design modification.

Both parts share identical contact finish specifications (gold mating, tin-lead or tin post finish), operating temperature range, voltage rating, and flammability certification. The packaging difference (tube for M80-4012042) does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can M80-4012042 be used as a direct replacement for M80-4012001 in existing assemblies?

A: Yes. The M80-4012042 is mechanically and electrically equivalent to the M80-4012001. All critical parameters including connector type, position count, pitch, mounting method, termination, and fastening are identical. No design modifications are required.

Q: What is the difference between the contact finish specifications for the two parts?

A: Both parts specify gold plating at the mating interface with identical thickness (12.0µin / 0.30µm). The post contact finish differs slightly: M80-4012001 uses tin-lead, while M80-4012042 uses tin. This difference does not affect substitution compatibility.

Q: Why is the M80-4012001 listed as obsolete?

A: The M80-4012001 has been discontinued by Harwin Inc. The M80-4012042 is the active product replacement within the Datamate J-Tek series.

Q: Does the packaging difference (tube for M80-4012042) affect compatibility?

A: No. Packaging affects only handling, storage, and logistics. The connector itself is identical regardless of packaging format.

Q: Are there any compliance differences between these parts?

A: The M80-4012042 is ROHS3 compliant, while the M80-4012001 is RoHS non-compliant. Both maintain identical REACH and ECCN classifications. For applications requiring RoHS compliance, the M80-4012042 is the appropriate selection.

Q: What is the operating temperature range for both connectors?

A: Both the M80-4012001 and M80-4012042 operate across -55°C to 125°C, suitable for automotive, general purpose, and military applications.
