Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS regulations. Selection between substitute options depends on specific application requirements:

For Tin-Plated Contact Finish: Parts 67996-406HLF and 67997-406HLF provide tin plating matching the original Molex 0702800591 specification. These parts use phosphor bronze contact material and support operating temperatures of -65°C to 125°C and -65°C to 130°C respectively.

For Gold-Plated Contact Finish: Parts 67996-106HLF, 67996-206HLF, 67997-106HLF, 67997-206HLF, 68602-206HLF, 77313-101-06LF, 77313-102-06LF, and 77313-118-06LF provide gold or gold GXT™ plating. These alternatives offer enhanced corrosion resistance and contact reliability. Operating temperature ranges extend to -65°C to 130°C for most variants.

For Extended Post Length: Parts 67997-106HLF, 67997-206HLF, 67997-406HLF, 68602-206HLF, 77313-101-06LF, 77313-102-06LF, and 77313-118-06LF feature longer contact post lengths (0.120" to 0.150") compared to the original specification (0.175"), accommodating different PCB thicknesses and assembly requirements.

For High Inventory Availability: Part 67997-206HLF offers the highest inventory level at 38,396 units, followed by 67996-206HLF at 9,515 units and 67996-106HLF at 9,309 units.

Frequently Asked Questions (FAQ)

Q: Can I substitute a gold-plated connector for the tin-plated Molex 0702800591?

A: Yes. Gold-plated alternatives such as 67996-106HLF, 67996-206HLF, 67997-106HLF, 67997-206HLF, 68602-206HLF, 77313-101-06LF, 77313-102-06LF, and 77313-118-06LF are functionally compatible. Gold plating provides superior corrosion resistance and contact durability. Verify that your application does not require specific tin-plated contact specifications before substitution.

Q: What is the difference between BERGSTIK® and BERGSTIK® II series?

A: Both series maintain identical electrical and mechanical specifications for 6-position 2.54mm pitch headers. BERGSTIK® II represents a newer product line designation. All parts listed are functionally interchangeable based on pitch, position count, row spacing, and contact configuration.

Q: Are there differences in contact post length among the substitute parts?

A: Yes. The original Molex 0702800591 specifies 0.175" contact post length. Amphenol ICC (FCI) BERGSTIK® II variants offer 0.095" (67996 series), 0.120" (67997 series), and 0.150" (68602 series) post lengths. BERGSTIK® variants (77313 series) provide 0.095", 0.120", and 0.135" post lengths. Select post length based on your PCB thickness and assembly requirements.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are RoHS Compliant or ROHS3 Compliant. The original Molex 0702800591 is ROHS3 Compliant. All alternatives meet or exceed this compliance level.

Q: What is the difference between contact finish thickness specifications?

A: Contact finish thickness varies among substitutes. The original Molex 0702800591 specifies 150.0µin (3.81µm) tin plating. Amphenol ICC (FCI) alternatives provide 30.0µin (0.76µm), 15.0µin (0.38µm), or 100.0µin (2.54µm) plating thickness depending on the specific part number. Thicker plating provides extended contact life and corrosion resistance in demanding environments.

Q: Can I use parts with different operating temperature ranges?

A: Yes, if your application requirements fall within the substitute part's temperature specification. The original Molex 0702800591 does not specify an operating temperature range. Amphenol ICC (FCI) substitutes support -65°C to 125°C (67996 series) or -65°C to 130°C (67997, 68602, and 77313 series). Select based on your thermal environment requirements.

Q: Are there packaging differences between substitute options?

A: Yes. The original Molex 0702800591 is supplied in Bulk packaging. Amphenol ICC (FCI) BERGSTIK® II variants (67996, 67997, 68602 series) are supplied in Bag packaging. BERGSTIK® variants (77313 series) are supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What contact material is used in the substitute parts?

A: All Amphenol ICC (FCI) substitute parts use phosphor bronze contact material, compared to the copper alloy specified in the original Molex 0702800591. Phosphor bronze provides superior spring characteristics and contact reliability while maintaining electrical conductivity and mechanical durability.
