Substitute Part Grouping Explanation

Substitution of the 68021-672 is determined by strict adherence to the following core parameters:

Connector Type: Header (male pin contact type)
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 72
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Termination: Solder
Current Rating: 3A per Contact
Material Flammability Rating: UL94 V-0

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in contact finish, contact material, insulation material, and operating temperature ranges are secondary considerations that do not prevent functional substitution when the primary parameters align.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence of the 68021-672. The primary distinction between substitute options is regulatory compliance status.

RoHS Compliance Consideration: The original 68021-672 is RoHS non-compliant. All substitute parts (802-80-072-20-001101, 802-V3-072-20-001101, 892-70-072-20-002101, 892-80-072-20-001101, 892-80-072-20-002101, and M20-9743646) are ROHS3 compliant. This compliance upgrade is a direct benefit for new designs and applications subject to RoHS regulations.

Operating Temperature Range: The 68021-672 operates from -65°C to 125°C. Preci-Dip substitutes (802 and 892 series) maintain -55°C to 125°C operation, which covers most industrial and commercial applications. The Harwin M20-9743646 operates from -40°C to 105°C, suitable for standard commercial temperature ranges but with reduced low-temperature capability.

Contact Finish Variations: Substitute parts offer tin or gold contact finishes. Gold-finished options (802-V3-072-20-001101, 892-70-072-20-002101) provide enhanced corrosion resistance compared to tin finishes. Selection depends on environmental exposure and long-term reliability requirements.

Connector Style: The Harwin M20-9743646 is specified as "Header, Cuttable," providing additional design flexibility for applications requiring custom position counts.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 68021-672 with any of the listed substitute parts?

A: Yes. All listed parts maintain the core electrical and mechanical parameters: 72-position, 2-row header configuration at 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, and 3A per contact current rating. Physical footprint and mating interface are identical.

Q: What is the primary reason to transition from the 68021-672?

A: The 68021-672 is obsolete. All substitute parts are active products with current manufacturing support and inventory availability, ensuring long-term supply chain continuity.

Q: Does RoHS compliance affect electrical performance?

A: No. ROHS3 compliance of substitute parts reflects material composition changes (lead-free solder, restricted substances) but does not alter electrical characteristics, current rating, or voltage performance relative to the original part.

Q: Which substitute part has the widest operating temperature range?

A: The Preci-Dip 802 and 892 series parts operate from -55°C to 125°C. The Harwin M20-9743646 operates from -40°C to 105°C. For applications requiring the original -65°C lower limit, the Preci-Dip options are preferred.

Q: Are there differences in contact material between substitutes?

A: Yes. The 68021-672 uses phosphor bronze contacts. Preci-Dip substitutes use brass contacts with tin or gold finish. Harwin M20-9743646 uses brass contacts with tin finish. Brass provides equivalent electrical performance and current-carrying capacity for this application.

Q: Can the Harwin M20-9743646 be cut to custom position counts?

A: Yes. The M20-9743646 is specified as "Cuttable," allowing custom configuration. Other substitutes are fixed 72-position assemblies.

Q: What is the voltage rating difference between the original and substitutes?

A: The 68021-672 is rated at 110V. Preci-Dip substitutes are rated at 150VDC, providing higher voltage capability. Harwin M20-9743646 does not specify a voltage rating in the provided data but maintains equivalent electrical isolation and insulation properties.
