Substitute Part Grouping Explanation
Substitution for the 76308-118 is determined by strict alignment of the following critical parameters:
Primary Matching Criteria:
- Connector type: Receptacle (female socket contact)
- Number of positions: 18
- Pitch: 0.100" (2.54mm)
- Mounting: Through hole, solder termination
- Fastening: Push-pull mechanism
- Contact finish (mating): Gold plating
Secondary Compatibility Factors:
- Insulation height tolerance (0.335" ±0.059")
- Contact material composition (brass or phosphor bronze acceptable)
- Flammability rating: UL94 V-0 or equivalent
- Contact finish thickness: 30.0µin ±10µin acceptable range
Substitute parts are grouped into two categories: direct Amphenol ICC alternatives and cross-manufacturer equivalents from Molex, Preci-Dip, TE Connectivity, and Samtec. All listed substitutes maintain the 18-position, 0.100" pitch, gold-plated receptacle configuration required for mechanical and electrical compatibility.

Engineering Selection Recommendations
Primary Recommendation: Molex 0901471318
The Molex 0901471318 provides the closest electrical and mechanical match to the 76308-118. It maintains identical 18-position, 0.100" pitch receptacle configuration with gold mating contact finish at 30.0µin thickness, matching the original specification. The connector features active product status with ROHS3 compliance, addressing regulatory requirements for new designs. Operating temperature range (-55°C to 105°C) covers standard industrial applications, though it does not extend to the full temperature range of some alternatives.
Secondary Recommendation: TE Connectivity 6-534237-6
The TE Connectivity 6-534237-6 AMPMODU Mod IV receptacle offers equivalent performance with extended operating temperature range (-65°C to 125°C) and RoHS compliance. Gold contact finish at 30.0µin matches the original specification. Insulation height of 0.340" (8.64mm) is within acceptable tolerance of the 76308-118 at 0.335" (8.51mm). This option provides superior temperature performance for applications requiring extended thermal operating windows.
Alternative for RoHS Compliance: Preci-Dip 316-83-118-41-012101
The Preci-Dip 316-83-118-41-012101 socket connector provides ROHS3 compliance with gold mating contact finish at 29.5µin (0.75µm), within specification tolerance. Operating temperature range extends to -55°C to 125°C. Insulation height of 0.354" (9.00mm) is within acceptable tolerance. This option is suitable for applications requiring compact form factor with elevated socket design.
Tin-Plated Alternative: Molex 0901471118
The Molex 0901471118 provides an active, ROHS3-compliant alternative with tin mating contact finish (40.0µin) instead of gold. This option is suitable for cost-sensitive applications where gold plating is not required. Identical 18-position, 0.100" pitch configuration and insulation height ensure mechanical compatibility.
Frequently Asked Questions (FAQ)
Q: Can the 76308-118 be directly replaced with any of these substitutes?
A: Direct replacement depends on application requirements. The Molex 0901471318 and TE Connectivity 6-534237-6 provide the closest electrical and mechanical equivalence with gold mating contacts matching the original 30.0µin specification. Preci-Dip socket connectors offer compatible performance with slightly different insulation heights. Verify PCB layout and mating connector compatibility before substitution.
Q: What is the difference between receptacle and socket connectors in this list?
A: Receptacle connectors (Molex, TE Connectivity) feature female socket contacts designed to accept male pins from a mating header. Socket connectors (Preci-Dip, Samtec) are elevated socket designs with similar female contact functionality but different mechanical mounting profiles. Both types are electrically compatible with standard 0.100" pitch male headers, but physical clearance and PCB layout must be verified.
Q: Are all substitutes RoHS compliant?
A: No. The original 76308-118 is RoHS non-compliant. All Molex, Preci-Dip, TE Connectivity, and Samtec alternatives listed are ROHS3 compliant or RoHS compliant, making them suitable for new designs subject to RoHS regulations. The Amphenol ICC 77311-101-03LF header is also RoHS compliant but differs in connector type and position count.
Q: What is the significance of contact finish thickness differences?
A: Contact finish thickness affects durability and mating cycle life. The original 76308-118 specifies 30.0µin (0.76µm) gold mating contact finish. Molex 0901471218 provides 15.0µin (0.38µm), which is thinner and may reduce contact life in high-cycle applications. Molex 0901471318 and TE Connectivity 6-534237-6 match the original 30.0µin specification. Preci-Dip options provide 29.5µin or flash gold, both within acceptable tolerance.
Q: Can I use the Samtec ESS-118-G-23 as a direct replacement?
A: The Samtec ESS-118-G-23 is an elevated socket connector with identical 18-position, 0.100" pitch configuration and gold mating contacts. However, insulation height is 0.300" (7.62mm) compared to the original 0.335" (8.51mm), representing a 0.035" reduction. This dimensional difference may affect PCB layout and mating connector clearance. Verify mechanical compatibility before substitution.
Q: What operating temperature range should I select?
A: The original 76308-118 does not specify operating temperature. Molex options provide -55°C to 105°C. TE Connectivity and Preci-Dip options extend to -55°C to 125°C or -65°C to 125°C. Select based on application thermal requirements. Extended temperature range options (TE Connectivity, Preci-Dip) are recommended for industrial and automotive applications.
Q: Are there packaging differences between substitutes?
A: Yes. Molex and TE Connectivity supply in tube packaging. Preci-Dip and Samtec supply in bulk packaging. Amphenol ICC 77311-101-03LF is supplied in bulk. Verify packaging requirements for production planning and inventory management.
