Substitute Part Grouping Explanation

Substitution for the 68021-140 is based on strict electrical and mechanical compatibility criteria. All substitute parts must meet the following requirements:

Critical Parameters for Substitution:

Number of Positions: 40
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Contact Type: Male Pin
Termination: Solder
Current Rating: 3A per Contact (minimum)
Operating Temperature Range: Must encompass or match -65°C ~ 125°C
Material Flammability Rating: UL94 V-0

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalent The 68021-140HLF is the active production equivalent from the same manufacturer and series, differing only in packaging (Bulk) and RoHS compliance status (RoHS Compliant).

Category 2: Cross-Manufacturer Substitutes Parts from Preci-Dip (802-V3-040-20-001101, 892 series), 3M (929838-01-20), and Harwin (M20 series) meet the core electrical and mechanical specifications. These parts maintain the 40-position, 2-row, 2.54mm pitch configuration with equivalent current and voltage ratings. Minor variations in contact length, contact finish, and insulation material do not affect functional compatibility within the specified electrical parameters.

Engineering Selection Recommendations

Primary Recommendation: 68021-140HLF The Amphenol ICC 68021-140HLF is the direct active equivalent from the original manufacturer. It maintains identical electrical and mechanical specifications while offering RoHS Compliance and active product status. This part is the preferred choice for new designs and ongoing production requiring continuity with the original BERGSTIK® II series.

Secondary Recommendations: Preci-Dip 802-V3-040-20-001101 and 892 Series The Preci-Dip 802-V3-040-20-001101 and 892 series parts (892-80-040-20-001101, 892-70-040-20-002101, 892-80-040-20-002101) are active, ROHS3-compliant alternatives. These parts meet all core electrical specifications and maintain the 40-position, 2-row, 2.54mm pitch configuration. The 892 series offers multiple contact finish options (Tin or Gold) to accommodate different application requirements.

Alternative Recommendations: Harwin M20 Series The Harwin M20-9742046 and M20-9952045 are active, ROHS3-compliant alternatives featuring cuttable connector design. These parts maintain electrical compatibility and offer tin or gold contact finishes. The M20 series is suitable for applications requiring modular connector flexibility.

Note on 3M 929838-01-20 The 3M 929838-01-20 meets core position and pitch specifications but operates at a reduced current rating (2.5A versus 3A) and narrower temperature range (-40°C ~ 105°C). This part is suitable only for applications within its specified electrical and thermal limits.

Temperature Consideration Applications requiring the full -65°C ~ 125°C operating range of the original 68021-140 should prioritize the 68021-140HLF or Preci-Dip alternatives, which maintain this specification. The Harwin and 3M options operate within -40°C ~ 105°C and -40°C ~ 105°C ranges respectively.

Frequently Asked Questions (FAQ)

Q: Can I use 68021-140HLF as a direct replacement for 68021-140? A: Yes. The 68021-140HLF is the active production equivalent from Amphenol ICC. It maintains identical electrical and mechanical specifications, differing only in packaging format (Bulk) and RoHS compliance status (RoHS Compliant). No design changes are required.

Q: What is the primary difference between the main part and its substitutes? A: The 68021-140 is obsolete. All substitute parts listed are active production items. The 68021-140HLF is the direct manufacturer equivalent. Cross-manufacturer substitutes from Preci-Dip, 3M, and Harwin meet the same electrical and mechanical specifications but may differ in contact finish options, insulation materials, and compliance certifications.

Q: Are there any electrical differences between the 68021-140 and the Preci-Dip 892 series? A: No. All 892 series parts (892-80-040-20-001101, 892-70-040-20-002101, 892-80-040-20-002101) maintain the same 40-position, 2-row, 2.54mm pitch configuration with 3A current rating and 150VDC voltage rating. The primary differences are contact finish (Tin or Gold) and insulation material composition.

Q: What is the difference between 892-80-040-20-001101 and 892-80-040-20-002101? A: Both parts are from the Preci-Dip 892 series with identical electrical specifications. The difference is in contact finish: 892-80-040-20-001101 features Tin finish on both mating and post contacts, while 892-80-040-20-002101 features Tin finish on mating contacts and Tin finish on post contacts. Both are ROHS3 compliant and active products.

Q: Can I use the 3M 929838-01-20 in place of the 68021-140? A: The 3M 929838-01-20 meets the position and pitch requirements but operates at 2.5A current rating (versus 3A) and a narrower temperature range (-40°C ~ 105°C versus -65°C ~ 125°C). Use this part only if your application operates within these reduced electrical and thermal specifications.

Q: What does "cuttable" mean for the Harwin M20 series? A: The Harwin M20-9742046 and M20-9952045 feature a cuttable connector design, allowing individual connector modules to be separated as needed. This provides design flexibility for applications requiring modular connector configurations while maintaining the same 40-position, 2-row, 2.54mm pitch electrical interface.

Q: Are all substitute parts RoHS compliant? A: No. The 3M 929838-01-20 is RoHS non-compliant. The 68021-140HLF, Preci-Dip 802-V3 and 892 series, and Harwin M20 series are all ROHS3 compliant. For applications requiring RoHS compliance, select from the compliant alternatives.

Q: What is the difference between the 802-V3-040-20-001101 and the 892 series? A: Both are Preci-Dip products with identical electrical specifications. The 802-V3 series features circular contact shape and brass material with PCT/Polyester/Glass-filled insulation. The 892 series features square contact shape and brass material with Polyamide/Nylon/Glass-filled insulation. Both are ROHS3 compliant and active products.

Q: Can I mix substitute parts from different manufacturers in the same design? A: Yes. All listed substitute parts maintain the same 40-position, 2-row, 2.54mm pitch configuration and are electrically compatible. However, verify mechanical fit and insulation height compatibility with your specific PCB layout, as minor variations in contact length and insulation height exist between manufacturers.
