Molex 0010892721 Equivalent & Substitute Parts
Part Overview
The Molex 0010892721 is a through-hole rectangular connector header with 72 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is part of the C-Grid 8624 series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute connectors maintain the same electrical and mechanical interface specifications while offering improved availability and compliance with current regulatory standards.

Engineering Selection Recommendations
For RoHS Compliant Applications: Select from Amphenol ICC BERGSTIK® II series parts with RoHS Compliant status: 10076801-101-72LF, 67996-172HLF, 67996-272HLF, 67996-372HLF, or 67996-472HLF. These parts meet current regulatory requirements for restricted substances and are suitable for new product designs subject to RoHS directives.
For Legacy or Non-Regulated Applications: The 3M 2372-6121-TG offers an alternative for applications where RoHS compliance is not required. This part maintains electrical and mechanical compatibility while providing different contact finish specifications.
For Active Product Status Priority: All listed substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the obsolete Molex original.
Contact Finish Selection:
- Gold-finished variants (10076801-101-72LF, 67996-172HLF, 67996-272HLF, 67996-372HLF) provide corrosion resistance matching the original specification.
- Tin-finished variant (67996-472HLF) offers cost optimization for applications where gold plating is not required.
- Contact finish thickness varies across substitutes; selection depends on specific environmental and reliability requirements.
Packaging Considerations: Amphenol ICC BERGSTIK® II series parts are available in both Bulk and Bag packaging. Bag packaging (indicated by "LF" suffix) is recommended for controlled moisture environments and traceability requirements.
Frequently Asked Questions (FAQ)
Q: Are all listed substitute parts electrically and mechanically compatible with the Molex 0010892721?
A: Yes. All substitute parts maintain the same mating pitch (0.100"), position count (72), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination type (solder). They are designed for direct interface compatibility in board-to-board applications.
Q: What is the difference between RoHS Compliant and RoHS non-compliant substitutes?
A: RoHS Compliant parts meet EU Directive 2011/65/EU restrictions on hazardous substances. RoHS non-compliant parts may contain lead or other restricted materials. Selection depends on application geography and regulatory requirements. For new designs, RoHS Compliant parts are recommended.
Q: How do contact finish variations affect connector performance?
A: Contact finish thickness and material affect corrosion resistance, contact resistance, and mating cycle durability. Gold finishes provide superior corrosion resistance; tin finishes offer cost reduction. The original Molex part specifies 30.0µin gold finish. Substitute parts offer variations from 10.0µin to 100.0µin. Selection should align with environmental exposure and reliability requirements.
Q: What is the significance of the "LF" suffix in part numbers like 67996-172HLF?
A: The "LF" suffix indicates Lead-Free composition and Bag packaging. These parts comply with RoHS directives and are packaged for moisture control and traceability in production environments.
Q: Can I use the 3M 2372-6121-TG as a direct substitute?
A: The 3M 2372-6121-TG is mechanically and electrically compatible but carries RoHS non-compliant status. It is suitable for legacy applications or environments where RoHS compliance is not mandated. For new designs, Amphenol ICC RoHS Compliant alternatives are preferred.
Q: What is the difference between BERGSTIK® and BERGSTIK® II series?
A: Both series maintain the same electrical and mechanical interface specifications for this 72-position configuration. BERGSTIK® II represents a newer product line with active manufacturing status and improved compliance certifications. BERGSTIK® (10076801-101-72LF) is also active and offers equivalent performance.
Q: Are there differences in operating temperature ranges among substitutes?
A: Yes. The original Molex part does not specify an operating temperature range. Substitute parts specify ranges from -55°C to 130°C. Amphenol ICC BERGSTIK® II parts rated for -65°C to 125°C provide extended low-temperature performance suitable for automotive and industrial applications.
Q: How should I select between different Amphenol ICC BERGSTIK® II variants?
A: Selection is based on contact finish requirements and compliance needs. All BERGSTIK® II variants maintain identical mechanical dimensions and electrical performance. Differentiation is by contact finish type (gold or tin) and finish thickness. Choose based on environmental exposure, cost constraints, and reliability specifications.
