MIT-038-01-L-D Equivalent & Substitute Parts Reference

Part Overview

The MIT-038-01-L-D is a 76-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 maintains Active product status with 1033 units in current inventory stock.

Identification of equivalent and substitute parts becomes necessary when original stock availability is limited, when alternative sourcing is required for supply chain optimization, or when design flexibility permits the use of functionally compatible components from different manufacturers while maintaining electrical and mechanical performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MIT-038-01-L-D is determined by alignment across the following critical parameters:

Electrical Parameters:

• Position count: 76 positions (exact match required)
• Pitch spacing: 0.025" (0.64mm) (exact match required)
• Row configuration: 2 rows (exact match required)
• Contact finish material: Gold plating (exact match required)
• Ground bus and board guide features (exact match required)

Mechanical Parameters:

• Surface mount mounting type (exact match required)
• Connector category: Rectangular connectors (exact match required)

Compliance Parameters:

• RoHS compliance status (equivalent or higher compliance acceptable)
• ECCN classification: EAR99 (exact match required)

The substitute part 2-5767004-3 from TE Connectivity AMP Connectors satisfies these substitution criteria through matching electrical and mechanical specifications, though it represents a different connector type (receptacle versus header) and series designation (MICTOR versus Q Strip® MIT).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MIT-038-01-L-D): The MIT-038-01-L-D remains the specified component for applications designed around the Q Strip® MIT series header configuration with outer shroud contacts. This part maintains Active product status with established supply availability and ROHS3 compliance certification.

Substitute Part Selection (2-5767004-3): The 2-5767004-3 from TE Connectivity serves as a functional substitute when the receptacle configuration is compatible with system design requirements. This part provides higher inventory availability (2188 units) and increased contact finish thickness (30.0µin versus 10.0µin), which may provide enhanced durability in high-cycle mating applications. Both parts maintain Active product status and EAR99 export classification.

Compliance Considerations: Both parts satisfy RoHS compliance requirements. The MIT-038-01-L-D carries ROHS3 certification, while the 2-5767004-3 carries standard RoHS compliance. The TE Connectivity part includes REACH Unaffected status and defined Moisture Sensitivity Level (MSL) rating of 1 (Unlimited).

Physical Integration: The height above board differs between parts (4.27mm versus 6.00mm), which may impact PCB layout and component clearance planning. The TE Connectivity part supports multiple mated stacking heights (6.6mm through 22.86mm), providing flexibility for connector stack configurations.

Frequently Asked Questions (FAQ)

Q: Can the 2-5767004-3 directly replace the MIT-038-01-L-D in existing designs?

A: Direct replacement requires design compatibility verification. While both parts share identical position count (76), pitch (0.025"), row configuration (2), mounting type (surface mount), and contact finish (gold), they differ in connector type (header versus receptacle) and physical height above board (4.27mm versus 6.00mm). System design must accommodate the receptacle configuration and increased height.

Q: What are the key electrical compatibility factors between these parts?

A: Both parts maintain identical electrical specifications: 76 positions, 0.025" pitch, 2-row configuration, gold contact finish, board guide, and ground bus features. These parameters ensure electrical path compatibility when mating interface design permits receptacle-to-header pairing.

Q: How do the contact finish specifications differ?

A: The MIT-038-01-L-D specifies 10.0µin (0.25µm) gold plating thickness, while the 2-5767004-3 specifies 30.0µin (0.76µm). The thicker plating on the TE Connectivity part provides increased contact durability and may extend service life in applications requiring frequent mating cycles.

Q: What packaging differences exist between these parts?

A: The MIT-038-01-L-D ships in Tray packaging, while the 2-5767004-3 ships in Tube packaging. Packaging selection may impact handling procedures, storage requirements, and integration with automated assembly processes.

Q: Are both parts suitable for RoHS-compliant applications?

A: Yes. The MIT-038-01-L-D carries ROHS3 compliance certification, and the 2-5767004-3 carries RoHS compliance certification. Both parts satisfy RoHS requirements for lead-free and restricted substance compliance.

Q: What is the significance of the MSL rating on the TE Connectivity part?

A: The 2-5767004-3 carries Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This simplifies logistics and storage management compared to parts with higher MSL ratings.

Q: How do the mated stacking heights affect system design?

A: The MIT-038-01-L-D does not specify mated stacking heights. The 2-5767004-3 supports multiple stacking heights (6.6mm, 9mm, 10.92mm, 12.57mm, 17.96mm, 18.75mm, 20mm, 22.86mm), enabling flexible connector stack configurations for applications requiring multiple mating levels or daisy-chain connectivity.
