Engineering Selection Recommendations

Direct Manufacturer Equivalent: M20-8760446R from Harwin Inc. is the primary active equivalent. This part maintains identical electrical and mechanical specifications to the M20-8760446P, including contact length, insulation height, and material composition. The M20-8760446R is available in Tape & Reel packaging and carries active product status with ROHS3 compliance.

Cross-Manufacturer Alternatives:

Samtec TSM-104 series parts (TSM-104-02-F-DV, TSM-104-02-F-DV-A, TSM-104-02-F-DV-A-P, TSM-104-02-F-DV-A-P-TR, TSM-104-02-F-DV-LC, TSM-104-02-F-DV-P, TSM-104-02-F-DV-P-TR) provide functional equivalence with extended operating temperature range (-55°C ~ 125°C) and gold-plated mating contacts. All Samtec alternatives maintain ROHS3 compliance and Moisture Sensitivity Level 1. Packaging options include Tube and Tape & Reel configurations. Variants with "-A" suffix include board guide features; "-P" suffix indicates pick-and-place compatibility; "-LC" suffix provides board lock functionality.

Molex 0879200830 (C-Grid 87920 series) offers functional compatibility with ROHS3 compliance and active product status. This part features Liquid Crystal Polymer insulation material and Copper Alloy contacts. Insulation height is 0.090" (2.29mm), which differs from the main part specification of 0.100" (2.54mm).

Amphenol ICC 71277-408H (BERGSTIK® II series) maintains mechanical and electrical compatibility with UL94 V-0 flammability rating and Moisture Sensitivity Level 1. This part carries RoHS non-compliant status and is not recommended for applications requiring RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can M20-8760446R be used as a direct replacement for M20-8760446P? A: Yes. M20-8760446R is the active equivalent from Harwin Inc. with identical electrical and mechanical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. unspecified).

Q: What is the key difference between Harwin M20-8760446R and Samtec TSM-104 series alternatives? A: Contact length differs: M20-8760446R maintains 0.228" (5.80mm) mating contact length matching the original part, while Samtec TSM-104 series parts feature 0.320" (8.13mm) mating contact length. Samtec parts also offer extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 105°C) and gold-plated mating contacts instead of tin plating.

Q: Are all substitute parts RoHS3 compliant? A: No. Amphenol ICC 71277-408H is RoHS non-compliant. All other alternatives, including M20-8760446R and the complete Samtec TSM-104 series, maintain ROHS3 compliance.

Q: What packaging options are available for substitute parts? A: Harwin M20-8760446R is supplied in Tape & Reel format. Samtec TSM-104 series parts are available in Tube packaging, with specific variants (TSM-104-02-F-DV-A-P-TR and TSM-104-02-F-DV-P-TR) supplied in Tape & Reel. Amphenol ICC 71277-408H is supplied in Bulk packaging.

Q: Does insulation height variation affect compatibility? A: Insulation height is a critical mechanical parameter. The main part and most substitutes specify 0.100" (2.54mm). Molex 0879200830 specifies 0.090" (2.29mm), which may affect mating stack height and board layout compatibility. Verify PCB design constraints before selection.

Q: Which substitute part offers the widest operating temperature range? A: All Samtec TSM-104 series alternatives operate from -55°C ~ 125°C, providing the widest temperature range compared to the original M20-8760446P specification of -40°C ~ 105°C.

Q: What is the significance of Samtec part number suffixes? A: Samtec TSM-104 variants use suffix notation: "-A" indicates board guide feature; "-P" indicates pick-and-place compatibility; "-LC" indicates board lock functionality; "-TR" indicates Tape & Reel packaging. Base part TSM-104-02-F-DV provides standard configuration without these features.
