Key Parameters

Substitute Part Grouping Explanation

The Molex 0399800417 qualifies as a direct substitute based on the following alignment of critical parameters:

• Position Count: Both parts feature 17 positions per level with single-level configuration
• Header Type: Both are male pin headers with partial shroud design
• Orientation: Both are vertical through-hole mounted
• Electrical Ratings: Identical current (10 A UL) and voltage (300 V UL) specifications
• Termination: Both use solder termination
• Material Composition: Identical brass contacts and polyamide/nylon housing
• Operating Temperature: Both rated to 140°C
• Compliance: Both ROHS3 compliant

The primary difference is pitch specification: the substitute operates at 5.08mm (0.200") versus the original 5.00mm (0.197"). This represents a 0.08mm variance within standard manufacturing tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0399800417 is the active equivalent for the obsolete Molex 0399900417. Selection of the substitute part is supported by:

• Product Status: The substitute maintains active product status, ensuring continued availability and manufacturing support
• Compliance Alignment: Both parts maintain identical ROHS3 compliance and EAR99 export classification
• Electrical Equivalence: Current and voltage ratings are identical, supporting direct functional replacement in existing circuit designs
• Mechanical Compatibility: Vertical through-hole mounting, solder termination, and material specifications are unchanged

The pitch variance of 0.08mm between the two parts falls within standard PCB design tolerances for this connector category and does not preclude mechanical or electrical substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0399800417 be used as a direct replacement for the 0399900417 in existing designs?

A: Yes. Both parts share identical electrical ratings (10 A, 300 V), termination method (solder), mounting type (through-hole vertical), and material specifications. The pitch difference of 0.08mm is within standard manufacturing tolerances for this component class.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The pitch difference represents the center-to-center spacing between adjacent contact positions. The 0.08mm variance is typical between Eurostyle series variants and does not affect electrical performance or standard PCB layout compatibility for this connector category.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The active substitute part (0399800417) provides equivalent functionality with current manufacturing support and availability.

Q: Are there packaging differences between the two parts?

A: The original part lists packaging as unspecified, while the substitute is packaged in bulk. Both maintain identical electrical and mechanical specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited) and EAR99 export classification, supporting use in regulated applications.
