Parameter Comparison

Engineering Selection Recommendations

77317-803-10LF (Amphenol ICC) is the primary substitute for the obsolete 77317-803-10. This direct equivalent maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The expanded operating temperature range (-65°C ~ 130°C) and specified current rating (3A per Contact) provide enhanced documentation for design validation. Selection of this part eliminates obsolescence risk while preserving design compatibility.

M20-9740542 and M20-9740546 (Harwin Inc.) are manufacturer-recommended alternatives suitable for applications where the Amphenol ICC direct equivalent is unavailable. Both parts meet all critical mechanical and electrical parameters. The M20-9740542 features gold mating contact finish, while the M20-9740546 features tin mating contact finish. Both are ROHS3 compliant with active product status. The cuttable connector type provides design flexibility for custom configurations. Operating temperature range (-40°C ~ 105°C) is narrower than the 77317-803-10LF but remains suitable for standard industrial applications. Contact material composition (Brass vs. Phosphor Bronze) and insulation material (Polyamide/Nylon 6T vs. Thermoplastic) represent minor material variations that do not affect functional compatibility for standard board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can the 77317-803-10LF be used as a direct replacement for the obsolete 77317-803-10?

A: Yes. The 77317-803-10LF is a direct equivalent with identical pitch (0.100"), position count (10), row configuration (2 rows), mounting type (through-hole right-angle), and contact specifications. The primary differences are active product status and RoHS compliance.

Q: What are the key differences between the Amphenol ICC 77317-803-10LF and the Harwin M20-9740542?

A: Both parts share identical pitch, position count, row spacing, mounting type, and fastening mechanism. Differences include: contact material (Phosphor Bronze vs. Brass), insulation material (Thermoplastic vs. Polyamide/Nylon 6T), operating temperature range (-65°C ~ 130°C vs. -40°C ~ 105°C), and connector type classification (Breakaway vs. Cuttable). These variations do not affect functional compatibility for standard board-to-board applications.

Q: What is the difference between M20-9740542 and M20-9740546?

A: Both parts are mechanically and electrically identical. The primary difference is the mating contact finish: M20-9740542 features gold plating, while M20-9740546 features tin plating. Contact finish selection depends on application requirements for corrosion resistance and signal integrity.

Q: Are all substitute parts RoHS compliant?

A: The 77317-803-10 is RoHS non-compliant. The 77317-803-10LF is RoHS Compliant. The Harwin M20-9740542 and M20-9740546 are ROHS3 Compliant. RoHS compliance status should be verified against specific regulatory requirements for your application.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided that the design accommodates minor dimensional variations. The Harwin M20 series parts have slightly longer contact posts (0.118" vs. 0.100") and greater insulation height (0.200" vs. 0.190"), which may require PCB layout verification. Contact length differences (0.228" vs. 0.230" mating) are within typical manufacturing tolerances.

Q: What is the current rating for these connectors?

A: The 77317-803-10 does not specify a current rating. The 77317-803-10LF, M20-9740542, and M20-9740546 are all rated at 3A per contact, supporting up to 30A total for the 10-position configuration.

Q: What packaging options are available?

A: The 77317-803-10 packaging is not specified. The 77317-803-10LF is supplied in Bulk packaging. The Harwin M20-9740542 and M20-9740546 are supplied in Bulk packaging.
