M20-8761642 Equivalent & Substitute Parts

Part Overview

The M20-8761642 is a rectangular connector header manufactured by Harwin Inc., designed for surface mount applications with 32 positions at 2.54mm pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The connector features a cuttable header design with unshrouded configuration, suitable for board-to-board or cable interconnections in industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M20-8761642 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)

Substitute Categories:

1. Direct Position Equivalent (32 Positions): TSM-116-01-T-DV-P by Samtec Inc. matches the exact position count and all primary mating parameters, providing a direct functional replacement with active product status.

2. Extended Position Variant (36 Positions): M20-8761842 by Harwin Inc. maintains all primary mating parameters but increases position count to 36. This part shares the same series base (M20-876) and offers active product status, suitable for applications requiring additional contact positions within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (32-Position Requirement): TSM-116-01-T-DV-P by Samtec Inc. is the appropriate selection. This part maintains identical position count and all critical mating parameters. The substitute carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The extended operating temperature range (-55°C to 105°C) provides additional thermal margin compared to the obsolete M20-8761642.

For Extended Capacity Applications (36-Position Requirement): M20-8761842 by Harwin Inc. is suitable when additional contact positions are acceptable within the design. This part remains within the same manufacturer family (M20 series), shares identical mating pitch and row spacing, and carries active product status with ROHS3 compliance. The 36-position configuration accommodates expanded interconnection requirements while maintaining mechanical and electrical compatibility with the same connector family ecosystem.

Compliance Considerations: Both substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's regulatory and handling requirements. All three parts carry EAR99 ECCN classification and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can TSM-116-01-T-DV-P directly replace M20-8761642 in existing designs? A: Yes. Both parts share identical position count (32), pitch (2.54mm), row spacing (2.54mm), mounting type (surface mount), and termination method (solder). The mating interface is functionally equivalent. Design verification should confirm that the different contact material (phosphor bronze vs. brass) and contact finish (tin vs. gold) are acceptable for the application's electrical requirements.

Q: What is the primary difference between M20-8761842 and M20-8761642? A: The M20-8761842 provides 36 positions compared to 32 positions in the M20-8761642. All other mating parameters, including pitch, row spacing, and mounting configuration, remain identical. This part is suitable only if the design can accommodate the additional connector length and contact count.

Q: Why is M20-8761642 listed as obsolete? A: Product status reflects manufacturer lifecycle decisions. The M20-8761842 (36-position variant) and TSM-116-01-T-DV-P (32-position equivalent from Samtec) are active alternatives that provide equivalent or extended functionality.

Q: Are there electrical performance differences between the substitute parts? A: M20-8761642 and M20-8761842 both specify 3A per contact and 250V rating. TSM-116-01-T-DV-P does not provide current and voltage specifications in the available data. Contact material differs (brass with gold finish vs. phosphor bronze with tin finish), which may affect contact resistance and corrosion characteristics in specific environments.

Q: What packaging options are available for these parts? A: M20-8761642 is supplied in standard packaging (not specified). M20-8761842 is available in bulk packaging. TSM-116-01-T-DV-P is supplied in tube packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) rating, and are REACH Unaffected. Material flammability rating is UL94 V-0 for all parts, ensuring consistent regulatory compliance across substitution options.
