Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M20-6102005 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• 40-position connector configuration
• 0.100" (2.54mm) pitch spacing
• 2-row layout
• Through-hole solder termination
• Gold contact finish
• UL94 V-0 flammability compliance
• ROHS3 compliance

Substitute Categories:

Category 1: Direct Harwin Equivalent (M20-6102045) Identical electrical and mechanical specifications with active product status, representing the current production replacement for the obsolete M20-6102005.

Category 2: Cross-Manufacturer PC/104 Stackthrough (4P01-2D02-DA) 3M-manufactured stackthrough connector matching core PC/104 specifications with equivalent current rating and contact configuration.

Category 3: Alternative Socket Connector (ESQ-120-14-G-D) Samtec elevated socket connector with matching 40-position, 2.54mm pitch configuration. Differs in connector style (socket vs. stackthrough) and operating temperature range, suitable for applications requiring elevated socket geometry.

Parameter Comparison

Engineering Selection Recommendations

M20-6102045 (Harwin Inc.) This part is the primary recommended substitute. It maintains identical electrical and mechanical specifications to the M20-6102005 while offering active product status and superior inventory availability (3095 units). Both parts share the same series designation (M20) and base product number (M20-610), ensuring design compatibility. ROHS3 compliance and UL94 V-0 certification are maintained. This substitute is suitable for direct replacement in existing designs.

4P01-2D02-DA (3M) This cross-manufacturer substitute meets all core PC/104 stackthrough specifications with equivalent 3A current rating and gold contact finish. Operating temperature range is -40°C to 105°C, which covers the lower bound of the original part's -55°C specification. ROHS3 compliance and UL94 V-0 certification are maintained. Selection of this part requires verification that the -40°C minimum temperature meets application requirements.

ESQ-120-14-G-D (Samtec Inc.) This elevated socket connector provides an alternative geometry with enhanced current capacity (5.7A per contact) and extended operating temperature range (-55°C to 125°C). The socket configuration differs from the stackthrough design of the original part, requiring PCB layout and mating interface verification. This substitute is appropriate for applications requiring higher current capacity or elevated connector geometry. ROHS3 compliance and UL94 V-0 certification are maintained.

Frequently Asked Questions (FAQ)

Q: Can M20-6102045 be used as a direct replacement for M20-6102005? A: Yes. M20-6102045 is the active production equivalent with identical connector type, position count, pitch, mounting method, and electrical ratings. Both parts are Harwin Inc. products within the M20 series and share the same base product number (M20-610).

Q: What is the key difference between the 4P01-2D02-DA and the original M20-6102005? A: The 4P01-2D02-DA is manufactured by 3M and has a minimum operating temperature of -40°C compared to -55°C for the M20-6102005. All other electrical and mechanical parameters, including 40-position configuration, 2.54mm pitch, 3A current rating, and gold contact finish, are equivalent.

Q: When should ESQ-120-14-G-D be selected instead of the other substitutes? A: The ESQ-120-14-G-D should be selected when the application requires elevated socket connector geometry, higher current capacity (5.7A per contact), or extended operating temperature range (-55°C to 125°C). The socket configuration requires different mating interface design compared to stackthrough connectors.

Q: Are all substitute parts ROHS3 compliant? A: Yes. M20-6102045, 4P01-2D02-DA, and ESQ-120-14-G-D are all ROHS3 compliant with UL94 V-0 flammability ratings, matching the compliance profile of the M20-6102005.

Q: What is the pitch specification for all listed parts? A: All parts, including the main M20-6102005 and all substitutes, operate at 0.100" (2.54mm) pitch spacing with 2-row, 40-position configuration, ensuring mechanical compatibility in PC/104 applications.

Q: Does packaging differ between the main part and substitutes? A: The M20-6102005 packaging is not specified. M20-6102045, 4P01-2D02-DA, and ESQ-120-14-G-D are all supplied in tube packaging, which is standard for through-hole connectors.
