MEC1-120-02-F-D-EM2-TR Equivalent & Substitute Parts

Part Overview

The MEC1-120-02-F-D-EM2-TR is a 40-position female card edge connector manufactured by Samtec Inc., designed for dual edge applications with 0.039" (1.00mm) pitch spacing. This connector features phosphor bronze contacts with gold finish, loop bellows contact type, and is rated for operating temperatures from -55°C to 125°C. The part is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The MEC1-120-02-F-D-EM2-TR is supplied in tape and reel packaging format.

Identifying equivalent and substitute parts is necessary when the original packaging format is unavailable, when alternative mounting configurations are required, or when inventory constraints necessitate sourcing from alternative stock conditions while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the MEC1-120-02-F-D-EM2-TR is permissible with the MEC1-120-02-F-D-EM2 based on the following criteria:

Electrical Compatibility Parameters:

• Identical number of positions (40)
• Identical pitch spacing (0.039" / 1.00mm)
• Identical contact material (Phosphor Bronze)
• Identical contact finish (Gold)
• Identical contact type (Loop Bellows)
• Identical operating temperature range (-55°C ~ 125°C)

Mechanical Compatibility Parameters:

• Identical card type (Non Specified - Dual Edge)
• Identical number of rows (2)
• Identical card thickness (0.062" / 1.57mm)
• Identical gender (Female)
• Identical termination method (Solder)
• Identical insulation material (Liquid Crystal Polymer)

Regulatory Compliance:

• Both parts maintain ROHS3 compliance
• Both parts have MSL 1 (Unlimited)

The primary difference between these parts is the packaging format (Tape & Reel versus Tray) and mounting configuration (Board Edge, Straddle Mount versus Surface Mount with Board Guide feature). These differences do not affect the electrical or core mechanical interface characteristics of the connector itself.

Parameter Comparison

Engineering Selection Recommendations

Both the MEC1-120-02-F-D-EM2-TR and MEC1-120-02-F-D-EM2 maintain active product status and full ROHS3 compliance. Selection between these parts should be based on:

Packaging Requirements: The MEC1-120-02-F-D-EM2-TR is supplied in tape and reel format, suitable for automated assembly processes. The MEC1-120-02-F-D-EM2 is supplied in tray format, suitable for manual assembly or alternative handling methods.

Mounting Configuration: The MEC1-120-02-F-D-EM2-TR is configured for board edge, straddle mount applications. The MEC1-120-02-F-D-EM2 includes a board guide feature and is configured for surface mount applications. The mounting type difference requires verification of PCB design compatibility.

Inventory Availability: Current inventory shows 790 units of MEC1-120-02-F-D-EM2-TR and 1552 units of MEC1-120-02-F-D-EM2 in stock.

Frequently Asked Questions (FAQ)

Q: Are the MEC1-120-02-F-D-EM2-TR and MEC1-120-02-F-D-EM2 electrically interchangeable?

A: Yes. Both connectors have identical electrical specifications including 40 positions, 0.039" pitch, phosphor bronze contacts with gold finish, loop bellows contact type, and identical operating temperature range (-55°C to 125°C).

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (tape & reel versus tray) and mounting configuration (board edge straddle mount versus surface mount with board guide). The electrical interface and core mechanical dimensions remain identical.

Q: Does the board guide feature on the MEC1-120-02-F-D-EM2 affect compatibility?

A: The board guide feature is an additional mechanical element on the MEC1-120-02-F-D-EM2. Compatibility depends on PCB design. If the PCB is designed for the straddle mount configuration of the MEC1-120-02-F-D-EM2-TR, the board guide on the MEC1-120-02-F-D-EM2 may require design verification.

Q: Are both parts RoHS compliant?

A: Yes. Both the MEC1-120-02-F-D-EM2-TR and MEC1-120-02-F-D-EM2 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Which part should I select for automated assembly?

A: The MEC1-120-02-F-D-EM2-TR in tape and reel packaging is designed for automated assembly processes.

Q: Which part should I select for manual assembly?

A: The MEC1-120-02-F-D-EM2 in tray packaging is suitable for manual assembly operations.
