Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Position Count: 32 positions (exact match required)
Pitch: 0.100" (2.54mm) mating pitch (exact match required)
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing (exact match required)
Mounting Type: Surface Mount (exact match required)
Contact Type: Male Pin (exact match required)
Termination: Solder (exact match required)
Fastening Type: Push-Pull (exact match required)
Connector Style: Board to Board or Cable (exact match required)
Insulation Material: Polyamide (PA6T) or Liquid Crystal Polymer (LCP) acceptable
Contact Material: Brass or Phosphor Bronze acceptable
Compliance: ROHS3 Compliant, UL94 V-0 rated (minimum requirements)

All substitute parts listed below meet these core electrical and mechanical parameters. Variations in contact finish thickness, contact length, and operating temperature range represent acceptable engineering tolerances within the connector category.

Engineering Selection Recommendations

Direct Equivalent (32-Position Match): The Samtec TSM-116 series connectors with 32 positions provide direct electrical and mechanical equivalence to the M20-8761642P. All TSM-116-02 variants maintain identical pitch, row configuration, contact type, and termination specifications. These parts are active products with ROHS3 compliance and UL94 V-0 flammability rating, meeting the compliance requirements of the original component.

Position-Variant Alternative: The M20-8761842 from Harwin Inc. offers a 36-position configuration within the same M20 series. This part maintains identical electrical and mechanical parameters except for position count, making it suitable only for applications where additional positions are required or acceptable.

Samtec TSM-116 Variants: Selection among TSM-116-02 variants depends on packaging requirements and specific feature needs:

Standard variants (F-DV, FM-DV, G-DV, H-DV) differ in contact finish thickness and post finish specifications
Board Guide feature (-A suffix) provides mechanical alignment enhancement
Board Lock feature (-LC suffix) provides mechanical retention
Packaging options include Bulk, Tube, and Tape & Reel (TR) configurations

All listed substitutes are active products with established supply chains and full ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can M20-8761842 replace M20-8761642P directly? A: M20-8761842 is mechanically and electrically compatible but features 36 positions instead of 32. Direct substitution is possible only if the application can accommodate the additional positions or if they remain unused.

Q: What is the primary difference between Harwin M20 and Samtec TSM-116 connectors? A: Both maintain identical pitch (2.54mm), row spacing, and contact configuration. Primary differences include contact material (Brass vs. Phosphor Bronze), insulation material (Polyamide vs. Liquid Crystal Polymer), and operating temperature range (-40°C to 105°C vs. -55°C to 125°C for Samtec).

Q: Are all TSM-116-02 variants electrically interchangeable? A: Yes. All TSM-116-02 variants maintain identical electrical specifications. Differences in part numbers reflect variations in contact finish thickness, post finish material, and packaging format, not electrical performance.

Q: What packaging options are available for TSM-116-02 connectors? A: Samtec offers TSM-116-02 in Bulk, Tube, and Tape & Reel (TR) packaging. Selection depends on assembly process requirements and volume considerations.

Q: Does operating temperature range affect substitution suitability? A: The original M20-8761642P operates from -40°C to 105°C. Samtec TSM-116 variants extend this to -55°C to 125°C, providing broader environmental capability. Substitution is valid for applications within the original temperature range.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original component's regulatory status.
