Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-111626-1 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (50), pitch (0.079"/2.00mm), number of rows (2), row spacing (0.079"/2.00mm), cable termination method (IDC), wire gauge (28 AWG), and contact finish (gold). Parts meeting all these criteria are classified as direct equivalents or active alternatives. Parts with identical electrical and mechanical specifications but differing in product status, compliance certifications, or secondary features (such as strain relief or polarizing keys) are listed as suitable substitutes based on functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

2-111626-3 (TE Connectivity AMP Connectors) is the primary direct equivalent for the 1-111626-1. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The 2-111626-3 is suitable for direct replacement in applications where RoHS3 compliance is required or preferred.

152250-0103-GB (3M) and 152250-0113-GB (3M) are functionally equivalent alternatives from a different manufacturer. Both parts meet all core electrical and mechanical requirements and carry active product status with ROHS3 compliance. The 152250-0113-GB includes additional features (polarizing key and strain relief) not present in the original 1-111626-1. Selection between these 3M alternatives depends on whether the additional features are compatible with the application's mechanical design.

158350-211015 (3M) shares identical electrical and mechanical parameters but is classified as obsolete and carries a reduced contact finish thickness (15.0µin versus 30.0µin). This part is not recommended for new designs or applications requiring extended service life due to its obsolete status and lower contact finish specification.

Frequently Asked Questions (FAQ)

Q: Can the 2-111626-3 be used as a direct replacement for the 1-111626-1?

A: Yes. The 2-111626-3 maintains identical specifications across all critical parameters: 50 positions, 0.079" pitch, 2 rows, IDC termination, 28 AWG wire gauge, and gold contact finish. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What is the difference between the 3M 152250-0103-GB and 152250-0113-GB?

A: Both parts are electrically and mechanically equivalent to the 1-111626-1. The 152250-0113-GB includes a polarizing key and strain relief features not present in the 152250-0103-GB. Selection depends on whether the application's mechanical design accommodates or requires these additional features.

Q: Why is the 158350-211015 not recommended as a substitute?

A: While the 158350-211015 meets core electrical and mechanical requirements, it carries obsolete product status and features a reduced contact finish thickness (15.0µin versus 30.0µin). The lower contact finish thickness may impact long-term reliability and contact resistance performance.

Q: Are there compatibility concerns when substituting between TE Connectivity and 3M parts?

A: No compatibility concerns exist for the listed substitutes. All parts share identical pitch, row spacing, number of positions, and IDC termination specifications. Mechanical fit and electrical performance are equivalent across manufacturers.

Q: What is the significance of RoHS3 compliance for these connectors?

A: RoHS3 compliance indicates conformance to current environmental and hazardous substance restrictions. The 1-111626-1 is RoHS non-compliant, while the 2-111626-3 and 3M alternatives (152250-0103-GB and 152250-0113-GB) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant alternatives are necessary.

Q: Can the 1-111626-1 be used interchangeably with the 158350-211015?

A: While both parts share identical electrical and mechanical specifications, the 158350-211015 is obsolete and features reduced contact finish thickness. For new designs or applications requiring extended service life, the active alternatives (2-111626-3 or 3M parts) are preferred.
