MIT-019-01-L-D Equivalent & Substitute Parts Reference

Part Overview

The MIT-019-01-L-D is a 38-position rectangular connector header manufactured by Samtec Inc. as part of the Q Strip® MIT series. This surface mount component features outer shroud contacts with gold plating and is designed for high-density interconnect applications requiring mixed technology connectivity. The part is currently in active production status with 955 units available in inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector type, position count, pitch, mounting method, contact finish, and compliance certifications. Two substitute parts have been qualified for this application based on matching core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIT-019-01-L-D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Position count: 38 positions
• Pitch: 0.025" (0.64mm)
• Contact finish: Gold plating
• Number of rows: 2

Mechanical Parameters:

• Mounting type: Surface Mount
• Features: Board Guide, Ground Bus (Plane)
• Connector category: Rectangular Connectors

Compliance Parameters:

• RoHS3 Compliance requirement
• ECCN classification: EAR99
• HTSUS code: 8536.69.4040

The identified substitutes are receptacle connectors from TE Connectivity AMP Connectors (MICTOR series) that maintain electrical and mechanical compatibility through matching position count, pitch, mounting method, contact finish, and feature set. Both substitute parts satisfy the core substitution criteria based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 2-5767004-2

The TE Connectivity part number 2-5767004-2 is the preferred substitute for the MIT-019-01-L-D. This part maintains active product status and full ROHS3 compliance, matching the regulatory requirements of the main part. The 38-position receptacle configuration with 0.025" pitch, surface mount technology, and gold-plated contacts provides electrical and mechanical equivalence. The higher contact finish thickness (30.0µin versus 10.0µin) represents an enhanced specification. The increased height above board (0.236" versus 0.168") must be evaluated for PCB layout compatibility in space-constrained applications.

Secondary Substitute: 2-767004-2

The TE Connectivity part number 2-767004-2 shares identical electrical and mechanical specifications with 2-5767004-2 but carries obsolete product status and RoHS non-compliance. This part is suitable only for legacy system maintenance or applications where RoHS compliance is not required. The significantly higher inventory level (623,600 units) may provide cost advantages for high-volume applications where regulatory compliance is not a constraint.

Selection Criteria:

For new designs and applications requiring RoHS3 compliance, select 2-5767004-2. For legacy system support where RoHS compliance is not applicable, 2-767004-2 remains functionally equivalent. Verify PCB layout accommodation for the increased height above board dimension (6.00mm versus 4.27mm) before final component selection.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the MIT-019-01-L-D?

A: Substitution is based on matching position count (38), pitch (0.025"), mounting type (surface mount), contact finish (gold), and feature set (board guide, ground bus plane). The substitute must maintain the same electrical interface and mechanical footprint compatibility.

Q: Why are the substitute parts receptacles while the main part is a header?

A: Headers and receptacles are complementary connector types designed to mate with each other. In a complete connector system, the header (MIT-019-01-L-D) mates with a receptacle. The listed substitutes represent the receptacle half of equivalent connector pairs from different manufacturers.

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

A: The main part specifies 10.0µin (0.25µm) gold plating, while substitutes specify 30.0µin (0.76µm). The thicker plating on substitute parts provides enhanced durability and wear resistance. Both thicknesses meet gold plating standards for connector applications.

Q: Can I use 2-767004-2 in a new product design?

A: The 2-767004-2 is obsolete and RoHS non-compliant. For new designs, use 2-5767004-2, which maintains active status and full ROHS3 compliance. The 2-767004-2 is appropriate only for legacy system maintenance where RoHS compliance is not required.

Q: What is the impact of the different height above board dimensions?

A: The main part has a height of 0.168" (4.27mm), while substitutes measure 0.236" (6.00mm). This 0.068" (1.73mm) difference must be verified against PCB layout constraints, component clearance requirements, and enclosure dimensions before substitution.

Q: Are the packaging differences significant?

A: The main part is supplied in trays while substitutes are supplied in tubes. This affects handling, storage, and automated assembly processes. Verify that your assembly equipment and logistics processes accommodate the different packaging format.

Q: What compliance certifications apply to these parts?

A: The MIT-019-01-L-D and 2-5767004-2 are both ROHS3 compliant with EAR99 ECCN classification. The 2-767004-2 is RoHS non-compliant and REACH affected. Regulatory requirements for your application determine which parts are acceptable.
