Molex 0016021111 Socket Contact Equivalent & Substitute Parts

Part Overview

The Molex 0016021111 is a socket contact connector designed for the SL 71851 series rectangular connector system. This component is a gold-plated crimp socket contact rated for 22-24 AWG wire gauges, currently in active production status. Socket contacts are essential termination components in modular connector assemblies, providing the receptive interface for mating pin contacts. Identifying equivalent and substitute parts is necessary when managing inventory across different packaging formats or when sourcing from alternative stock locations while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0016021111 is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must be Molex SL 71851 series components to ensure mechanical compatibility with connector housings and mating pin contacts
• Contact Type and Termination: Socket contact with crimp termination is non-negotiable for assembly compatibility
• Wire Gauge Rating: 22-24 AWG specification must be maintained for proper current-carrying capacity and contact retention
• Contact Finish: Gold plating at 30.0µin (0.76µm) thickness ensures consistent electrical performance and corrosion resistance
• Compliance Standards: ROHS3 compliance and REACH unaffected status must be preserved for regulatory requirements

The substitute part 0016021111 differs from the main part only in packaging format (Bulk versus Cut Tape), which does not affect the electrical or mechanical performance of the individual contact component.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0016021111 and 0016021115 are functionally equivalent socket contacts for SL 71851 series rectangular connector applications. Selection between these parts should be based on packaging and inventory management requirements:

The 0016021111 in Cut Tape packaging is suitable for automated assembly processes and applications requiring controlled component dispensing. The 0016021115 in Bulk packaging is appropriate for high-volume manufacturing environments with in-house tape-and-reel processing capabilities or manual assembly operations.

Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The choice between them does not affect circuit performance, reliability, or compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 0016021115 (Bulk) be used as a direct replacement for the 0016021111 (Cut Tape)?

A: Yes. Both parts are identical socket contacts for the SL 71851 series. The only difference is packaging format. Electrical and mechanical performance are equivalent.

Q: Are there any compatibility issues when substituting between these part numbers?

A: No. Both parts are designed for the same connector housing and mating pin contacts. Wire gauge, contact finish, and termination method are identical.

Q: Does packaging format affect the contact performance or reliability?

A: No. Packaging format is a logistics consideration only. The individual contact component performance is unaffected by whether it is supplied in Cut Tape or Bulk format.

Q: What wire gauges are compatible with these socket contacts?

A: Both parts are rated for 22-24 AWG wire. Wire gauges outside this range are not compatible.

Q: Are these parts suitable for high-reliability applications?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting standard regulatory requirements. MSL rating of 1 indicates unlimited moisture sensitivity protection. Suitability for specific high-reliability applications depends on system-level requirements beyond component specifications.

Q: Can these socket contacts be used with non-Molex SL 71851 series housings?

A: No. These contacts are designed specifically for Molex SL 71851 series connector housings. Compatibility with other connector systems is not supported.
