Key Parameters

Substitute Part Grouping Explanation

Substitution between MEC1-108-02-L-D-EM2 and MEC1-108-02-L-D-EM2-TR is determined by the following critical parameters that remain constant across both parts:

• 16-position female connector configuration
• 0.039" (1.00mm) pitch spacing
• Dual edge card type with 0.062" (1.57mm) card thickness
• 2-row layout with loop bellows contact type
• Phosphor bronze contacts with gold finish (10.0µin thickness)
• Solder termination
• -55°C to 125°C operating temperature range
• Liquid Crystal Polymer insulation
• RoHS3 compliance and REACH unaffected status

The primary difference between these parts is packaging format: MEC1-108-02-L-D-EM2 is supplied in Tray packaging, while MEC1-108-02-L-D-EM2-TR is supplied in Cut Tape (CT) packaging. Additionally, the mounting type differs: Surface Mount versus Board Edge, Straddle Mount.

Parameter Comparison

Engineering Selection Recommendations

Both MEC1-108-02-L-D-EM2 and MEC1-108-02-L-D-EM2-TR maintain Active product status with identical electrical and mechanical specifications. Selection between these parts is determined by application requirements:

• Choose MEC1-108-02-L-D-EM2 (Tray packaging, Surface Mount) for applications requiring surface-mounted card edge connector installations.
• Choose MEC1-108-02-L-D-EM2-TR (Cut Tape packaging, Board Edge Straddle Mount) for applications requiring board edge straddle mounting configurations or when Cut Tape packaging is specified for automated assembly processes.

Both parts satisfy RoHS3 compliance and REACH unaffected status requirements. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MEC1-108-02-L-D-EM2-TR be used as a direct replacement for MEC1-108-02-L-D-EM2?

A: Electrical and mechanical compatibility is maintained between these parts. However, the mounting type differs: MEC1-108-02-L-D-EM2 uses Surface Mount configuration while MEC1-108-02-L-D-EM2-TR uses Board Edge, Straddle Mount configuration. Substitution is valid only when the application PCB layout and mounting requirements support the straddle mount configuration.

Q: What is the significance of the packaging difference between Tray and Cut Tape?

A: Tray packaging is typically used for manual assembly or lower-volume production runs. Cut Tape (CT) packaging is designed for automated pick-and-place assembly equipment. The choice depends on manufacturing process requirements and assembly automation capabilities.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH unaffected designation. MSL rating of 1 (Unlimited) applies to both, indicating no moisture sensitivity restrictions.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must remain constant: 16-position female configuration, 0.039" (1.00mm) pitch, dual edge card type, 0.062" (1.57mm) card thickness, 2-row layout, phosphor bronze contacts with gold finish, loop bellows contact type, solder termination, and -55°C to 125°C operating temperature range.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation from -55°C to 125°C, supporting industrial and extended temperature range applications.
