Key Parameters

Substitute Part Grouping Explanation

The substitute part 1586041-2 (TE Connectivity AMP Connectors, VAL-U-LOK series) qualifies as a direct substitute based on the following critical parameters:

• Identical connector type (Header) and contact type (Male Pin)
• Matching position configuration (2 positions, 2 rows)
• Identical row spacing (0.165" / 4.20mm)
• Matching mounting style (Through Hole, Right Angle)
• Identical shrouding design (Shrouded - 4 Wall)
• Matching termination method (Solder)
• Equivalent electrical ratings (9A current, 600V voltage)
• Identical operating temperature range (-40°C ~ 105°C)
• Matching insulation material class (Polyamide/Nylon)
• Equivalent contact material and finish specifications
• Identical flammability rating (UL94 V-2)
• Matching compliance certifications (ROHS3, MSL 1)

Minor dimensional variations in contact post length (0.138" vs 0.142") and insulation height (0.394" vs 0.402") fall within acceptable mechanical tolerances for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

The 1586041-2 is the manufacturer-recommended substitute for the obsolete KF-N4200146. Selection of this substitute is supported by:

• Active product status of the substitute part, ensuring ongoing availability and supply chain continuity
• Full compliance with ROHS3 and matching regulatory certifications
• Identical electrical and thermal performance specifications
• Equivalent mechanical interface and mounting characteristics
• Established compatibility within industrial and general-purpose applications

The substitute part is available in bulk packaging with significantly higher inventory levels (30,222 units) compared to the original part, supporting both immediate replacement needs and long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1586041-2 be used as a direct replacement for the KF-N4200146 in existing designs?

A: Yes. Both connectors share identical row spacing (4.20mm), mounting orientation (through-hole right angle), shrouding configuration (4-wall), and electrical ratings (9A, 600V). The minor dimensional variations in post length and insulation height are within acceptable mechanical tolerances for PCB integration.

Q: What is the significance of the product status difference between the two parts?

A: The KF-N4200146 is obsolete, meaning it is no longer manufactured or supported by Harwin Inc. The 1586041-2 is active, ensuring continued availability, technical support, and supply chain reliability for new production and maintenance applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-2 flammability rating, EAR99 export classification, and MSL 1 moisture sensitivity level. Both are suitable for the same regulatory environments and applications.

Q: What packaging options are available for the substitute part?

A: The 1586041-2 is supplied in bulk packaging, with 30,222 units currently in stock. The original KF-N4200146 packaging specification was not provided in the technical data.

Q: Are there any application restrictions when using the 1586041-2?

A: The substitute part is rated for general-purpose, industrial, and lighting applications. It maintains the same operating temperature range (-40°C to 105°C) and electrical specifications as the original part, with no application restrictions relative to the KF-N4200146.
