Engineering Selection Recommendations

All four substitute parts are active products from Amphenol ICC (FCI), providing long-term availability and supply chain stability compared to the obsolete Molex 0010892546. Selection among the substitutes should be based on the following factors:

Amphenol ICC 68020-454HLF (BERGSTIK® II Series): This part offers the lowest operating temperature range (-65°C to 125°C) and features tin plating on mating contacts rather than gold. It is suitable for applications where the reduced temperature range is acceptable and tin contact finish is compatible with the mating connector design.

Amphenol ICC 77317-103-54LF (BERGSTIK® Series): This part provides gold-plated mating contacts with GXT™ technology and operates across -65°C to 130°C. Contact length dimensions closely match the original Molex part (0.230" mating, 0.100" post), making it the most dimensionally compatible option for direct replacement in existing PCB layouts.

Amphenol ICC 77317-112-54LF (BERGSTIK® Series): This part features extended contact lengths (0.268" mating, 0.120" post) with gold GXT™ plating and -65°C to 130°C operating range. Selection of this variant is appropriate when deeper mating engagement or extended post length is required for specific application geometry.

Amphenol ICC 77317-804-54LF (BERGSTIK® Series): This part combines gold GXT™ plating with the thinnest mating contact finish (15.0µin) and extended post length (0.120"). It operates across -65°C to 130°C and is suitable for applications requiring minimal contact finish thickness while maintaining gold plating properties.

All substitute parts carry RoHS compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 68020-454HLF be used as a direct replacement for the Molex 0010892546?

A: The 68020-454HLF meets all critical electrical and mechanical parameters including pitch, position count, row configuration, and connector type. However, it features tin-plated mating contacts instead of gold plating and operates at a lower maximum temperature (-65°C to 125°C versus unspecified for the original). Compatibility depends on whether the mating connector accepts tin plating and whether the operating temperature range is sufficient for the application.

Q: What is the difference between the three BERGSTIK® variants (77317-103-54LF, 77317-112-54LF, and 77317-804-54LF)?

A: All three BERGSTIK® parts share identical pitch, position count, and row spacing. The primary differences are contact length dimensions and contact finish thickness. The 77317-103-54LF provides the closest dimensional match to the original Molex part. The 77317-112-54LF offers extended contact lengths for deeper mating engagement. The 77317-804-54LF combines extended post length with minimal mating contact finish thickness.

Q: Are all substitute parts RoHS compliant?

A: Yes, all four substitute parts are RoHS compliant. The original Molex 0010892546 is ROHS3 compliant, and all Amphenol ICC substitutes meet RoHS requirements, ensuring compatibility with environmental regulations.

Q: What packaging options are available for the substitute parts?

A: The 68020-454HLF is supplied in Bag packaging. The 77317-103-54LF is supplied in Bulk packaging. The 77317-112-54LF and 77317-804-54LF are both supplied in Bag packaging. Packaging selection may affect inventory management and handling procedures.

Q: Do all substitute parts support breakaway configuration?

A: The 68020-454HLF is specified as Header type without explicit breakaway designation. The 77317-103-54LF, 77317-112-54LF, and 77317-804-54LF are all specified as Header, Breakaway type, matching the original Molex part configuration.

Q: What is the current rating for the substitute parts?

A: All four substitute parts are rated for 3A per contact. The original Molex 0010892546 does not specify a current rating in the provided data.

Q: Are the substitute parts suitable for automotive and medical applications?

A: The original Molex 0010892546 is documented for automotive, medical, telecommunications, and general-purpose applications. All substitute parts meet UL94 V-0 flammability requirements and carry appropriate compliance certifications. Application suitability should be confirmed based on specific end-use requirements and any additional qualification standards required by the application domain.
