Amphenol ICC 76308-116 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76308-116 is a 16-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole PCB mounting with gold-plated mating contacts. This BergCon® series connector features push-pull fastening and solder termination for board-to-board or cable applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility through matching connector type, contact configuration, pitch, and mounting method while meeting modern compliance standards.

Substitute Part Grouping Explanation

Substitute parts for the 76308-116 are grouped based on strict electrical and mechanical compatibility criteria. All qualified substitutes must match the following mandatory parameters:

Connector type: Receptacle
Contact type: Female Socket
Number of positions: 16
Pitch - mating: 0.100" (2.54mm)
Number of rows: 1
Mounting type: Through Hole
Termination: Solder
Fastening type: Push-Pull
Contact finish - mating: Gold
Insulation height: 0.335" ± 0.005" (8.51mm ± 0.13mm)

Substitutes are categorized into two groups: direct equivalents from active manufacturers (Molex, TE Connectivity, Harwin, Preci-Dip, Samtec) and alternative socket configurations. Contact shape variations (square vs. circular) and contact material differences (brass vs. phosphor bronze vs. beryllium copper) are permitted within the same functional group, as these do not affect mating compatibility with standard 0.100" pitch headers.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

Molex 0901471216 and 0901471316 from the C-Grid 90147 series provide direct functional equivalence with identical pitch, position count, and insulation height. Both are active products with ROHS3 compliance, addressing the obsolescence of the original part. The 0901471316 matches the original gold contact finish thickness specification at 30.0µin (0.76µm), making it the closest electrical equivalent.

Harwin M20-7821642 and M20-7821646 offer active product status with enhanced voltage rating (1000V) and superior operating temperature range (-40°C to 105°C). The M20-7821642 maintains gold mating contact finish, while M20-7821646 uses tin finish. Both feature square contact geometry matching the original design.

TE Connectivity 6-534237-4 (AMPMODU Mod IV series) provides UL94 V-0 flammability rating and extended operating temperature range (-65°C to 125°C). Insulation height tolerance of 0.340" (8.64mm) represents a 0.09mm deviation from the original specification.

Secondary Substitutes (Functional Equivalence with Design Variations):

Preci-Dip 801-83-016-10-005101 and 801-87-016-10-005101 feature circular contact geometry and beryllium copper material, providing superior contact reliability. Both maintain 16-position, 0.100" pitch configuration with through-hole solder termination. The 801-87-016-10-005101 uses flash gold finish on mating contacts.

Samtec ESS-116-T-23 (elevated socket configuration) introduces reduced insulation height (0.300" vs. 0.335"), requiring PCB layout verification. Liquid crystal polymer insulation material and beryllium copper contacts provide enhanced performance characteristics. This variant is suitable for applications where elevated socket geometry is acceptable.

Compliance Considerations:

All active substitute parts meet ROHS3 compliance, addressing regulatory requirements for new designs. The original 76308-116 is RoHS non-compliant, making substitution necessary for applications subject to RoHS directives. Current rating specifications (2A to 3A) and voltage ratings (350V to 1000V) across substitutes exceed typical 0.100" pitch connector applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 76308-116 with any of these substitutes without PCB modification?

A: Molex 0901471216, 0901471316, Harwin M20-7821642, M20-7821646, and TE Connectivity 6-534237-4 maintain identical or near-identical insulation height (0.335" ± 0.005"), allowing direct PCB footprint compatibility. Samtec ESS-116-T-23 has reduced insulation height (0.300"), requiring PCB layout verification before substitution.

Q: What is the difference between receptacle and socket connector types in this list?

A: Receptacle connectors (Molex, Harwin, TE Connectivity) accept male header pins and are mounted on the PCB. Socket connectors (Preci-Dip 801 series, Samtec ESS elevated sockets) also accept male pins but feature different contact geometries and materials. All are functionally compatible with standard 0.100" pitch headers.

Q: Does contact material affect mating compatibility?

A: No. Contact material (brass, phosphor bronze, beryllium copper) does not affect mechanical or electrical mating compatibility with standard 0.100" pitch male headers. Material selection influences contact reliability, wear resistance, and spring force characteristics but not basic connector function.

Q: Why do some substitutes have different contact finish thicknesses?

A: Contact finish thickness (ranging from 10.0µin to 30.0µin) affects contact durability and wear resistance. Thinner finishes (10.0µin) reduce material cost, while thicker finishes (30.0µin) provide extended contact life. All specified thicknesses are functionally adequate for standard applications.

Q: Is the tin-plated M20-7821646 compatible with the gold-plated original?

A: Yes. Tin and gold finishes are both acceptable mating surfaces for 0.100" pitch connectors. Tin finish provides cost reduction while maintaining electrical performance. Contact finish compatibility depends on the mating header type, not the receptacle finish alone.

Q: What is the significance of the elevated socket configuration in the Samtec ESS-116-T-23?

A: Elevated socket design raises the contact engagement point above the PCB surface, accommodating applications with limited PCB clearance or requiring specific stacking heights. This configuration requires verification that the reduced insulation height (0.300" vs. 0.335") does not conflict with PCB layout constraints.

Q: Are all substitutes RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original 76308-116 is RoHS non-compliant, making substitution mandatory for applications subject to RoHS directives (EU 2011/65/EU and amendments).

Q: Which substitute offers the best operating temperature range?

A: TE Connectivity 6-534237-4 provides the widest operating temperature range (-65°C to 125°C), followed by Preci-Dip and Samtec variants (-55°C to 125°C). Harwin M20 series is rated -40°C to 105°C. Selection depends on specific application thermal requirements.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, provided all substitutes maintain identical pitch (0.100"), position count (16), and mounting type (through-hole solder). Mixing different manufacturers is acceptable from an electrical standpoint, though design documentation should specify the approved part list to ensure consistency across production batches.
