Substitute Part Grouping Explanation

Substitute parts for the 68020-406H are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector type (Header)
Contact type (Male Pin)
Pitch configuration (0.100" / 2.54mm mating pitch)
Position count (6 positions in 2 rows)
Row spacing (0.100" / 2.54mm)
Mounting style (Through Hole, Right Angle)
Termination method (Solder)
Fastening mechanism (Push-Pull)
Current rating (3A per contact minimum)
Flammability rating (UL94 V-0)

The identified substitutes—Würth Elektronik 61300621021 and Harwin Inc. M20-9740346—meet all critical electrical and mechanical parameters. Variations in contact finish, insulation material composition, and operating temperature ranges are secondary parameters that do not prevent substitution but may require application-specific evaluation.

Engineering Selection Recommendations

All three parts maintain active product status and meet the core electrical and mechanical requirements for 6-position, 2.54mm pitch header applications with push-pull fastening and 3A current capacity.

The 68020-406H operates across an extended temperature range (-65°C to 125°C) compared to the substitute parts (-40°C to 105°C). Applications requiring operation below -40°C or above 105°C must retain the original Amphenol ICC part.

The 61300621021 (Würth Elektronik) features gold mating contact finish and is ROHS3 compliant, making it suitable for applications with RoHS compliance requirements. The M20-9740346 (Harwin Inc.) offers cuttable header functionality and is also ROHS3 compliant, providing design flexibility for custom position configurations.

The 68020-406H is RoHS non-compliant. Selection of substitute parts should align with regulatory and compliance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 61300621021 or M20-9740346 be used as direct replacements for the 68020-406H?

A: Both substitute parts share identical mating pitch (0.100" / 2.54mm), position count (6 in 2 rows), mounting style (through-hole right-angle), termination method (solder), and fastening type (push-pull). Electrical compatibility is established through matching current ratings (3A) and flammability ratings (UL94 V-0). Substitution is mechanically and electrically valid within the specified operating temperature ranges of each part.

Q: What are the temperature operating range differences?

A: The 68020-406H operates from -65°C to 125°C. Both substitute parts (61300621021 and M20-9740346) operate from -40°C to 105°C. Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 105°C must use the original 68020-406H.

Q: How do contact finish differences affect substitution?

A: The 68020-406H features tin mating contact finish. The 61300621021 features gold mating contact finish, which provides enhanced corrosion resistance and lower contact resistance. The M20-9740346 retains tin finish matching the original part. Contact finish selection depends on application environment and signal integrity requirements.

Q: What is the significance of the cuttable header feature on the M20-9740346?

A: The M20-9740346 is designated as a cuttable header, allowing custom position configurations through mechanical separation. The 68020-406H and 61300621021 are fixed 6-position designs. This feature provides design flexibility but does not affect direct substitution for fixed 6-position applications.

Q: Are there RoHS compliance differences?

A: The 68020-406H is RoHS non-compliant. Both substitute parts (61300621021 and M20-9740346) are ROHS3 compliant. Applications subject to RoHS regulations must use one of the compliant substitute parts.

Q: How do insulation material specifications affect compatibility?

A: The 68020-406H insulation material is not specified in available documentation. Both substitute parts use Polyamide (PA6T) / Nylon 6T insulation. This material composition supports the same operating temperature ranges and flammability ratings for the substitute parts and does not prevent substitution.
