MEC8-140-02-L-DV-A-TR Equivalent & Substitute Parts

Part Overview

The MEC8-140-02-L-DV-A-TR is an 80-position female card edge connector manufactured by Samtec Inc., designed for dual edge applications with 0.031" (0.80mm) pitch spacing. This connector features phosphor bronze contacts with gold finish, surface mount termination, and operates across -55°C to 125°C. The part is currently Active in product status and RoHS3 compliant.

Substitute parts are identified when packaging or distribution formats differ while maintaining identical electrical and mechanical specifications. The primary substitute for this part differs only in packaging configuration, allowing for equivalent performance in applications where the original packaging is unavailable or unsuitable for procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MEC8-140-02-L-DV-A-TR is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Number of positions (80), pitch (0.031"), contact material (phosphor bronze), contact finish (gold), and operating temperature range (-55°C to 125°C)
• Mechanical Specifications: Card type (dual edge), number of rows (2), card thickness (0.062"), mounting type (surface mount), and termination method (solder)
• Material & Compliance: Insulation material (LCP), RoHS3 compliance, and MSL rating (1)

The identified substitute part MEC8-140-02-L-DV-A maintains all electrical and mechanical specifications while differing only in packaging format (Tray versus Tape & Reel). This packaging difference does not affect connector performance, compatibility, or application suitability.

Parameter Comparison

Engineering Selection Recommendations

Both the MEC8-140-02-L-DV-A-TR and MEC8-140-02-L-DV-A are Active products from Samtec Inc. with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and procurement logistics:

• MEC8-140-02-L-DV-A-TR (Tape & Reel): Suitable for high-volume automated assembly processes where tape and reel packaging integrates directly with pick-and-place equipment.
• MEC8-140-02-L-DV-A (Tray): Suitable for manual assembly, lower-volume production, or applications where tray packaging is preferred for handling and storage.

Both parts deliver equivalent electrical performance and mechanical compatibility in applications requiring 80-position dual edge female connectors with 0.031" pitch and surface mount termination.

Frequently Asked Questions (FAQ)

Q: Are MEC8-140-02-L-DV-A-TR and MEC8-140-02-L-DV-A electrically identical?

A: Yes. Both parts have identical electrical specifications including 80 positions, 0.031" pitch, phosphor bronze contacts with gold finish, and -55°C to 125°C operating temperature range.

Q: What is the only difference between these two parts?

A: The packaging format. MEC8-140-02-L-DV-A-TR is supplied in Tape & Reel format, while MEC8-140-02-L-DV-A is supplied in Tray format. All connector specifications remain identical.

Q: Can I use MEC8-140-02-L-DV-A in place of MEC8-140-02-L-DV-A-TR?

A: Yes, provided your assembly process accommodates tray packaging instead of tape and reel. The connector itself is functionally equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MEC8-140-02-L-DV-A-TR and MEC8-140-02-L-DV-A are RoHS3 compliant with MSL rating 1 (Unlimited).

Q: What is the card thickness specification for these connectors?

A: Both parts are designed for 0.062" (1.57mm) card thickness with dual edge configuration and 2-row layout.
