Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 111626-4 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (20), pitch (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), cable termination method (IDC), wire gauge (28 AWG), contact finish (gold), and mounting configuration (free hanging in-line). All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional interchangeability within ribbon cable interconnect applications.

The substitute parts are grouped into two categories: direct manufacturer equivalents from TE Connectivity and cross-manufacturer alternatives from 3M and Adam Tech. Direct equivalents provide the highest assurance of form-fit-function compatibility. Cross-manufacturer alternatives offer equivalent electrical performance and mechanical interface characteristics while potentially providing enhanced features or improved product status.

Engineering Selection Recommendations

TE Connectivity 1-111626-9 is the primary recommended substitute. This part maintains identical electrical and mechanical specifications to the 111626-4 while offering active product status and ROHS3 compliance. As a direct manufacturer equivalent within the AMP-Latch series, it provides the highest assurance of design compatibility and supply chain continuity. Inventory availability is substantial at 1509 pieces.

3M 152220-0103-GB and 3M 152220-0113GB are cross-manufacturer alternatives that satisfy all core substitution parameters. Both parts are ROHS3 compliant with active product status. The 152220-0113GB includes additional features (polarizing key and strain relief) beyond the base specification. Both 3M parts carry REACH Unaffected certification. Selection between these 3M options depends on whether the polarizing key feature is required for the application.

Adam Tech 2FCS-20-SG is a functionally equivalent alternative with active product status and ROHS3 compliance. This part features a push-pull fastening mechanism and flash gold contact finish thickness, distinguishing it from the other substitutes. Wire gauge specification is not provided for this part. Selection of this alternative is appropriate when push-pull fastening is compatible with the application requirements.

All substitute parts maintain the critical parameters of 20-position, 2-row configuration with 2.00mm pitch and IDC ribbon cable termination. Product status and regulatory compliance favor selection of any active substitute over the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-111626-9 be used as a direct replacement for the 111626-4?

A: Yes. The 1-111626-9 maintains identical specifications across all critical parameters: 20 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing, IDC termination, 28 AWG wire gauge, gold contact finish at 30.0µin thickness, and free hanging in-line mounting. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What are the differences between the 3M 152220-0103-GB and 152220-0113GB?

A: Both parts are electrically and mechanically equivalent with identical core specifications. The 152220-0113GB includes additional features: a polarizing key and strain relief. The 152220-0103-GB provides strain relief only. Both are ROHS3 compliant and REACH unaffected. Selection depends on whether the polarizing key feature is required for the application.

Q: Does the Adam Tech 2FCS-20-SG have the same wire gauge as the original part?

A: The wire gauge specification for the 2FCS-20-SG is not provided in the technical data. The original 111626-4 specifies 28 AWG. Verification of wire gauge compatibility is necessary before selection of the Adam Tech part.

Q: What is the significance of contact finish thickness differences?

A: The 111626-4, 1-111626-9, and both 3M parts specify 30.0µin (0.76µm) gold contact finish thickness. The Adam Tech 2FCS-20-SG specifies flash gold finish thickness. Flash finish is thinner than the specified 30.0µin thickness. Contact finish thickness affects durability and electrical performance in high-cycle mating applications.

Q: Are all substitute parts RoHS compliant?

A: The 111626-4 is RoHS non-compliant. All substitute parts (1-111626-9, 152220-0103-GB, 152220-0113GB, and 2FCS-20-SG) are ROHS3 compliant. This compliance improvement is a significant advantage of substitution.

Q: What packaging options are available?

A: The 1-111626-9 is supplied in bulk packaging. The 3M parts (152220-0103-GB and 152220-0113GB) are supplied in bulk packaging. The Adam Tech 2FCS-20-SG is supplied in tray packaging. Packaging selection may affect procurement quantities and handling procedures.

Q: Can these connectors be used interchangeably in existing designs?

A: All substitute parts maintain the same connector type (receptacle), contact type (female socket), position count (20), pitch (2.00mm), row configuration (2 rows), and mounting style (free hanging in-line). Mechanical and electrical interchangeability is established. Design verification is required only if application-specific features (such as the polarizing key in the 152220-0113GB) are relevant to the existing design.
