Molex 0416952021 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0416952021 is a 4-position rectangular connector housing with 0.156" (3.96mm) pitch, designed for crimp contact termination in free-hanging inline applications. This part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing procurement and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or assembly modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across the following parameters: connector type (receptacle), number of positions (4), pitch (0.156"/3.96mm), number of rows (1), mounting configuration (free hanging inline), contact termination method (crimp), fastening mechanism (locking ramp), and contact gender (non-gendered). All identified substitutes meet these core electrical and mechanical requirements. Color variation (black vs. natural) does not affect functional interchangeability but may impact visual assembly identification. Insulation material composition (polyamide/nylon) is consistent across all parts. RoHS3 compliance and MSL rating are maintained across the substitute group.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (0009930400 and 0009503041) are active production components manufactured by Molex with full ROHS3 compliance and identical MSL ratings. Part 0009930400 maintains black color matching the original 0416952021, providing visual continuity in assembly documentation and field identification. Part 0009503041 offers natural color housing with equivalent electrical and mechanical performance. Selection between these substitutes should be based on color requirement for your specific application. Both parts maintain the KK396 series compatibility and support direct replacement without modification to mating connectors or circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can 0009930400 and 0009503041 be used interchangeably with 0416952021? A: Yes. All three parts share identical electrical and mechanical specifications: 4-position receptacle housings with 0.156" pitch, crimp termination, locking ramp fastening, and non-gendered contacts. The primary difference is product status (obsolete vs. active) and color variation.

Q: What is the significance of the color difference between black and natural housings? A: Color does not affect electrical or mechanical function. Selection depends on assembly identification requirements and visual traceability standards in your manufacturing process.

Q: Are the substitute parts available in the same packaging as the original? A: The original 0416952021 packaging is not specified in available data. Both substitutes are supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do all three parts require the same contact types? A: Yes. All housings are non-gendered receptacles designed for identical crimp contacts. The note "Contacts Not Included" applies uniformly across all three part numbers.

Q: Are there any compliance or certification differences between the parts? A: No. All three parts are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), EAR99 export classification, and identical HTSUS coding.
