Molex 0702800664 Equivalent & Substitute Parts
Part Overview
The Molex 0702800664 is a vertical header connector with 72 positions at 2.54mm pitch, designed for through-hole board-to-board applications. This unshrouded header features male pins with gold-plated mating contacts and tin-plated posts, constructed from copper alloy with liquid crystal polymer insulation. The connector is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.
Substitute parts are identified based on matching core electrical and mechanical parameters: 72-position configuration, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, push-pull fastening, and UL94 V-0 flammability rating. Amphenol ICC (FCI) BERGSTIK® II series connectors provide direct functional equivalence across multiple contact finish and post length variations.

Engineering Selection Recommendations
Primary Substitutes (Active Status, RoHS Compliant):
The Amphenol ICC (FCI) BERGSTIK® II series provides direct functional substitution across three contact post length variants. Selection depends on PCB stack-up requirements and mating connector depth specifications.
67996 Series (Post Length 0.095" / 2.41mm): Suitable for compact board-to-board applications with minimal stack height. Available in gold-plated (67996-172HLF, 67996-272HLF) and tin-plated (67996-472HLF) contact finishes. All variants maintain -65°C to 125°C operating range and RoHS compliance.
67997 Series (Post Length 0.120" / 3.05mm): Standard post length for general board-to-board interconnection. Offers extended operating temperature range to 130°C. Available in gold-plated variants with varying finish thicknesses (67997-172HLF, 67997-272HLF, 67997-372HLF) and tin-plated option (67997-472HLF). Bulk packaging available for production volumes.
68602 Series (Post Length 0.150" / 3.81mm): Extended post length for applications requiring deeper mating depth or additional solder joint standoff. Gold-plated contact finish with 30.0µin or 15.0µin thickness options. Available in bag (68602-172HLF) and bulk (68602-272HLF) packaging. Maintains 130°C maximum operating temperature.
Secondary Reference (Obsolete Status):
67997-572 is listed as obsolete with RoHS non-compliance. This part is retained for legacy system documentation only and should not be selected for new designs.
Compliance Considerations:
All recommended active substitutes maintain UL94 V-0 flammability rating, unlimited moisture sensitivity (MSL 1), and RoHS compliance. Contact finish selection (gold versus tin) does not affect functional compatibility but may influence cost and specific application requirements such as corrosion resistance or contact wear characteristics.
Frequently Asked Questions (FAQ)
Q: Can I substitute the Molex 0702800664 with any BERGSTIK® II connector?
A: Only BERGSTIK® II connectors with matching 72-position, 2-row, 2.54mm pitch configuration qualify as substitutes. The 67996, 67997, and 68602 series meet these criteria. Verify post length compatibility with your mating connector depth before selection.
Q: What is the difference between the 67996, 67997, and 68602 series?
A: The primary difference is contact post length. 67996 series features 0.095" posts for compact applications, 67997 series provides standard 0.120" posts, and 68602 series offers extended 0.150" posts for deeper mating requirements. All maintain 72-position configuration and 2.54mm pitch.
Q: Are gold-plated and tin-plated versions interchangeable?
A: Yes, within the same series. Gold-plated (67996-172HLF, 67996-272HLF) and tin-plated (67996-472HLF) versions of the 67996 series are electrically and mechanically compatible. Contact finish selection depends on application-specific corrosion resistance or wear requirements, not functional compatibility.
Q: Does packaging type (Bag vs. Bulk) affect connector performance?
A: No. Packaging type (Bag or Bulk) is a logistics consideration only and does not affect electrical or mechanical performance. Select based on inventory management and production volume requirements.
Q: Why is the 67997-572 listed if it is obsolete?
A: The 67997-572 is documented for reference in legacy system designs. It is RoHS non-compliant and should not be selected for new applications. Use active alternatives from the 67997 series instead.
Q: What operating temperature range should I select?
A: The Molex 0702800664 does not specify operating temperature limits. Amphenol ICC substitutes offer -65°C to 125°C (67996 series) or -65°C to 130°C (67997 and 68602 series). Select based on your application thermal requirements.
Q: Are there any mechanical compatibility issues between the Molex part and Amphenol substitutes?
A: No. All substitute parts maintain identical 2.54mm pitch, push-pull fastening, and square contact geometry. Mechanical compatibility is assured across all recommended active substitutes. Verify post length compatibility with your specific mating connector.
Q: What is the difference between 30.0µin, 15.0µin, and 100.0µin contact finish thickness?
A: These values represent gold or tin plating thickness on mating contacts. Thicker finishes (100.0µin) provide enhanced wear resistance for high-cycle mating applications. Thinner finishes (15.0µin) reduce material cost. All thicknesses meet functional requirements for standard board-to-board applications.
