M20-9983245 Equivalent & Substitute Parts

Part Overview

The M20-9983245 is an active rectangular connector header manufactured by Harwin Inc., designed for through-hole mounting applications. This 64-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-board and cable interconnection requirements. The part is in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M20-9983245 are qualified based on the following critical parameters that determine functional equivalence:

• Connector Configuration: 64 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Contact System: Male pin type with square contact shape
• Mounting Method: Through-hole solder termination
• Electrical Performance: 3A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1 rating
• Fastening: Push-pull fastening type
• Shrouding: Unshrouded configuration

The identified substitutes (68739-264HLF and 77313-101-64LF) maintain these core parameters while offering alternative contact materials, finishes, and operating temperature ranges. Variations in contact length, insulation material, and connector type (standard vs. breakaway) do not preclude substitution when the mating interface and electrical characteristics remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active production status and full compliance with RoHS and UL94 V-0 flammability requirements, ensuring regulatory alignment with the original M20-9983245.

The 68739-264HLF (BERGSTIK® II series) offers an extended operating temperature range of -65°C to 130°C compared to the M20-9983245's -40°C to 105°C specification. This part uses phosphor bronze contacts with gold or GXT™ finish and is suitable for applications requiring broader thermal performance.

The 77313-101-64LF (BERGSTIK® series) provides breakaway connector functionality with phosphor bronze contacts, gold or GXT™ finish, and tin-plated posts. This part also supports the extended -65°C to 130°C operating temperature range and includes thermoplastic insulation material.

Selection between these substitutes depends on specific application requirements regarding connector type (standard vs. breakaway), contact material preference, and thermal operating conditions. All three parts share identical mating pitch, position count, current rating, and fastening characteristics, ensuring mechanical and electrical compatibility at the mating interface.

Frequently Asked Questions (FAQ)

Q: Can the 68739-264HLF or 77313-101-64LF be used as direct replacements for the M20-9983245?

A: Yes, both parts are qualified substitutes based on matching connector configuration (64 positions, 2 rows, 0.100" pitch), contact system (male pin, square shape), mounting method (through-hole solder), current rating (3A per contact), and environmental compliance (UL94 V-0, RoHS, MSL 1). The mating interface is compatible across all three parts.

Q: What are the key differences between the substitute parts?

A: The 68739-264HLF uses standard header configuration with phosphor bronze contacts and extended temperature range (-65°C to 130°C). The 77313-101-64LF adds breakaway connector functionality, also with phosphor bronze contacts and extended temperature range. Both Amphenol ICC parts offer wider thermal operating windows than the original Harwin part.

Q: Are there any contact length variations that affect compatibility?

A: Contact length variations exist between parts (M20-9983245: 0.240" mating / 0.118" post; 68739-264HLF: 0.230" mating / 0.156" post; 77313-101-64LF: 0.230" mating / 0.095" post). These differences do not affect mating interface compatibility but may influence board layout and mechanical clearance considerations in specific applications.

Q: Do all three parts have the same RoHS compliance status?

A: The M20-9983245 is ROHS3 Compliant. Both substitute parts (68739-264HLF and 77313-101-64LF) are RoHS Compliant. All three parts meet RoHS requirements; the designation difference reflects compliance documentation timing but does not indicate functional or regulatory differences.

Q: What is the difference between the BERGSTIK® II and BERGSTIK® series?

A: The BERGSTIK® II series (68739-264HLF) is a standard header connector. The BERGSTIK® series (77313-101-64LF) includes breakaway functionality, allowing individual rows or sections to be separated. Both series maintain identical mating pitch and position configuration.

Q: Are moisture sensitivity levels equivalent across all three parts?

A: Yes, all three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
