Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC (FCI) 77311-146-11LF

The 77311-146-11LF is the preferred substitute for the obsolete TE Connectivity 104427-9. This part maintains identical position count (11), pitch spacing (0.100"/2.54mm), and contact configuration while offering active product status. The 77311-146-11LF provides equivalent current rating (3A per contact), extended operating temperature range (-65°C ~ 125°C), and RoHS compliance. The contact mating length (0.318"/8.08mm) and overall contact length (0.535"/13.59mm) are within acceptable tolerance of the original specification. Thermoplastic insulation material and UL94 V-0 flammability rating ensure functional equivalence.

Secondary Substitute: Amphenol ICC (FCI) 68004-111HLF

The 68004-111HLF serves as an alternative substitute with identical position count and pitch spacing. This part offers enhanced current rating (5A) and voltage rating (110V), exceeding the original 3A/30VAC specification. The BERGSTIK® II series provides active product status and RoHS compliance. The insulation height (0.100"/2.54mm) differs from the original (0.090"/2.29mm), and operating temperature range is not specified. This part is suitable for applications requiring higher electrical performance margins.

Compliance Considerations:

Both substitute parts provide RoHS compliance, addressing regulatory requirements not met by the obsolete original part. The REACH Affected status is consistent across all three parts. Both substitutes maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the 77311-146-11LF directly replace the 104427-9 in existing designs?

A: The 77311-146-11LF maintains all critical mechanical and electrical parameters required for direct substitution. The 11-position, 0.100" pitch header configuration, through-hole mounting, and unshrouded design are identical. Contact mating length and overall contact length are within acceptable tolerance. The extended operating temperature range (-65°C ~ 125°C) encompasses the original specification (-65°C ~ 105°C). Solder termination is compatible with the original press-fit/solder termination specification.

Q: What is the difference between the two substitute parts?

A: The 77311-146-11LF (BERGSTIK®) and 68004-111HLF (BERGSTIK® II) differ in electrical ratings and insulation height. The 77311-146-11LF provides 3A current rating matching the original part, while the 68004-111HLF provides 5A. The 68004-111HLF has insulation height of 0.100" (2.54mm) compared to 0.090" (2.29mm) on the original. The 77311-146-11LF offers specified operating temperature range (-65°C ~ 125°C), while the 68004-111HLF does not specify operating temperature.

Q: Are there packaging differences between the original and substitute parts?

A: The original 104427-9 packaging is not specified in the documentation. Both substitute parts are supplied in Bag packaging. This difference does not affect functional compatibility but may impact handling and storage procedures.

Q: Does the contact material change affect performance?

A: The original part uses Copper Alloy contacts, while both substitutes use Phosphor Bronze contacts. Both materials are standard for rectangular connectors in this category and provide equivalent electrical conductivity and reliability. The contact finish (Gold or Gold, GXT™) on substitutes meets or exceeds the original Gold finish specification.

Q: What is the significance of RoHS compliance on the substitute parts?

A: The original 104427-9 is RoHS non-compliant, while both substitute parts are RoHS Compliant. This compliance status is critical for applications subject to RoHS regulations in the European Union and other jurisdictions. RoHS compliance restricts hazardous substances including lead, cadmium, and mercury, making the substitute parts suitable for regulated markets.

Q: Can the 68004-111HLF be used in applications requiring the original voltage rating?

A: The 68004-111HLF provides 110V rating, which exceeds the original 30VAC specification. This part is suitable for applications requiring the original voltage rating and for applications requiring higher voltage performance. The enhanced voltage rating provides additional design margin.

Q: Are there any mechanical compatibility concerns with the substitute parts?

A: The contact mating length (0.318"/8.08mm) is identical across all three parts. The overall contact length varies slightly: original 0.528" (13.42mm), 77311-146-11LF 0.535" (13.59mm), and 68004-111HLF 0.525" (13.34mm). These variations are within standard manufacturing tolerances for rectangular connectors and do not affect mechanical compatibility in standard through-hole applications.

Q: What is the inventory status of the substitute parts?

A: The 77311-146-11LF has 721 pieces in stock, and the 68004-111HLF has 1076 pieces in stock. Both parts are available as new original components with active product status, ensuring long-term supply availability compared to the obsolete original part.
