Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M40-6201546 is determined by strict equivalence across the following critical parameters:

• Connector type and shroud configuration (Receptacle, Outer Shroud Contacts)
• Contact count and arrangement (15 positions, 2 rows)
• Contact pitch (0.039" / 1.00mm)
• Mounting technology (Surface Mount)
• Contact finish specification (Tin, 80.0µin thickness)
• Mechanical envelope (4.3mm mated stacking height, 0.130" height above board)
• Functional features (Board Guide, Solder Retention)
• Regulatory compliance (ROHS3, REACH Unaffected)

The M40-6201546R qualifies as a direct substitute based on full alignment with all specified parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

The M40-6201546R is the direct equivalent for the obsolete M40-6201546. Both parts maintain identical electrical and mechanical specifications, with full parameter alignment across connector configuration, contact arrangement, pitch, mounting method, and contact finish.

The M40-6201546R carries active product status, ensuring ongoing manufacturer support, availability, and compliance maintenance. Both parts satisfy ROHS3 and REACH regulatory requirements, with no compliance differentiation between the original and substitute.

Selection of the M40-6201546R eliminates obsolescence risk while preserving complete design compatibility with existing applications and PCB layouts designed for the M40-6201546.
