Key Parameters

Substitute Part Grouping Explanation

Substitution of the M40-4010646 is based on electrical and mechanical compatibility within the M40 series. The critical parameters that define substitutability are:

• Connector type (Header), contact type (Male Pin), and number of positions (6)
• Pitch specification (0.039" / 1.00mm mating pitch)
• Mounting configuration (Surface Mount, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Electrical ratings (1A current, 50V voltage minimum)
• Operating temperature range (-25°C ~ 85°C)
• Termination method (Solder) and fastening type (Push-Pull)
• Compliance certifications (UL94 V-0, ROHS3, REACH Unaffected)

The M40-4010646R is identified as the active equivalent within the M40 series, maintaining all critical electrical and mechanical parameters while offering improved product status and availability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the M40-4010646R directly replace the M40-4010646 in existing designs?

A: Yes. Both parts share identical electrical ratings (1A, 50V), mechanical dimensions (6-position, 1mm pitch, surface mount right-angle configuration), shrouding design (4-wall), and compliance certifications. The M40-4010646R is the active production equivalent.

Q: What is the primary difference between these parts?

A: The M40-4010646 is obsolete, while the M40-4010646R is active. The M40-4010646R also specifies voltage rating as 50VAC/DC for clarity. Insulation material differs (Polyamide PA9T in the original versus Liquid Crystal Polymer halogen-free in the substitute), and insulation height varies slightly (2.90mm versus 3.00mm).

Q: Are there packaging differences?

A: The M40-4010646R is supplied in Cut Tape (CT) packaging. Packaging specifications for the M40-4010646 were not provided in the original documentation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. Both have Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the contact material difference?

A: The M40-4010646 uses Phosphor Bronze contacts, while the M40-4010646R uses Copper Alloy contacts. Both are tin-finished and rated for 1A continuous current.
