Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8638PSC2006 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the 8638 series
• Contact Configuration: Female socket type with machined form factor
• Electrical Specifications: 12-14 AWG wire gauge capacity and crimp termination method
• Material Composition: Copper alloy base material with gold contact finish
• Mechanical Interface: D-Sub connector category with identical packaging format

The 8638PSC2006LF qualifies as a direct substitute based on complete alignment with these parameters. The primary distinction between the main part and substitute relates to termination finish specification and RoHS compliance status, which do not affect the core functional compatibility of the contact itself.

Parameter Comparison

Engineering Selection Recommendations

8638PSC2006: Select this part number when the application design explicitly requires RoHS non-compliant components or when existing inventory and supply chain documentation reference this specific part number. Product status is Active with established supply availability.

8638PSC2006LF: This part number is the preferred selection for new designs and applications subject to RoHS compliance mandates. The LF designation indicates lead-free termination finish (Tin instead of Tin-Lead), aligning with environmental and regulatory requirements. Inventory availability is higher at 1979 units, supporting production volume requirements. Both parts maintain identical electrical and mechanical specifications for D-Sub power contact applications.

Frequently Asked Questions (FAQ)

Q: Can 8638PSC2006LF be used as a direct replacement for 8638PSC2006?

A: Yes. Both parts share identical contact specifications including wire gauge (12-14 AWG), termination method (crimp), contact material (copper alloy), and contact finish (gold flash). The primary difference is the termination finish composition and RoHS compliance status, which do not affect electrical or mechanical compatibility in the connector interface.

Q: What does the "LF" designation indicate?

A: The "LF" suffix denotes lead-free termination finish. The 8638PSC2006LF uses tin-based termination instead of tin-lead, meeting RoHS compliance requirements for applications subject to environmental regulations.

Q: Are there packaging differences between these part numbers?

A: No. Both parts are supplied in Tape & Reel (TR) packaging format, maintaining identical handling, storage, and assembly process compatibility.

Q: Which part should be specified for new product designs?

A: The 8638PSC2006LF is the appropriate selection for new designs unless specific design constraints or legacy system requirements mandate the non-compliant variant. The LF version provides regulatory alignment and superior long-term supply chain stability.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
