Engineering Selection Recommendations

The 77311-118-09LF represents the primary substitute option, being an active product from the same manufacturer (Amphenol ICC) within the BERGSTIK® series. This part maintains identical mechanical and electrical interface specifications while offering RoHS compliance and an extended operating temperature range of -65°C to 125°C compared to the obsolete original.

The 3M 2309-6111-TG and 929450-01-09-I are cross-manufacturer alternatives suitable for applications where multi-source qualification is required. Both maintain the critical 9-position, 0.100" pitch header configuration with through-hole solder termination. The 2309-6111-TG operates across -55°C to 105°C with 3A per contact rating and RoHS non-compliant status. The 929450-01-09-I features a breakaway connector option, operates across -40°C to 105°C with 2.5A per contact rating, and is RoHS compliant.

For new designs requiring regulatory compliance, the 77311-118-09LF or 929450-01-09-I are recommended due to RoHS compliance status. For applications with extended temperature requirements, the 77311-118-09LF supports the widest operating range at -65°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 77311-118-09LF be used as a direct replacement for the obsolete 77311-118-09?

A: Yes. The 77311-118-09LF maintains identical mating pitch (0.100"), contact configuration (9 positions, single row), contact length specifications, and push-pull fastening. Both use square male pin contacts with solder termination for through-hole mounting. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What are the key differences between the Amphenol ICC and 3M substitute options?

A: The Amphenol ICC 77311-118-09LF remains within the same BERGSTIK® series with phosphor bronze contacts. The 3M options (2309-6111-TG and 929450-01-09-I) use copper alloy contacts and different insulation materials. The 929450-01-09-I includes a breakaway feature and operates at a lower current rating (2.5A vs. 3A). Contact length specifications vary slightly between manufacturers.

Q: Are there packaging differences between these substitutes?

A: The 77311-118-09LF is available in bulk packaging, while the original 77311-118-09 packaging is not specified. The 929450-01-09-I is also available in bulk. Packaging should be confirmed with the supplier based on production requirements.

Q: Which substitute is recommended for RoHS-compliant applications?

A: Both the 77311-118-09LF and 929450-01-09-I are RoHS compliant. The 2309-6111-TG is RoHS non-compliant. For regulatory compliance requirements, either the Amphenol ICC or 3M 929 series option is suitable.

Q: What is the operating temperature range for each substitute?

A: The 77311-118-09LF supports -65°C to 125°C, the 2309-6111-TG supports -55°C to 105°C, and the 929450-01-09-I supports -40°C to 105°C. Selection depends on application thermal requirements.

Q: Are the contact finish specifications identical across all substitutes?

A: Mating contact finishes are gold across all options. Post contact finishes vary: the original and 2309-6111-TG use tin-lead, the 77311-118-09LF uses tin, and the 929450-01-09-I uses gold. Contact finish thickness specifications also differ between parts.
