HSEC8-125-01-L-DV-A-L2-TR Equivalent & Substitute Parts

Part Overview

The HSEC8-125-01-L-DV-A-L2-TR is a 50-position female card edge connector from Samtec Inc.'s Edge Rate™ HSEC8 series. This dual-edge connector features gold-plated beryllium copper contacts with a 0.031" (0.80mm) pitch, designed for surface mount solder termination applications. The connector is rated for operating temperatures from -55°C to 125°C and is ROHS3 compliant with MSL 1 rating. Finding equivalent or substitute parts may be necessary due to packaging availability, lead time optimization, or inventory management requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the HSEC8-125-01-L-DV-A-L2-TR is determined by strict equivalence across the following critical parameters:

  • Connector Series & Base Number: Must be Edge Rate™ HSEC8 series with base product number HSEC8-125
  • Electrical Configuration: 50 positions, female gender, dual-edge, 0.031" (0.80mm) pitch
  • Physical Dimensions: 0.062" (1.57mm) card thickness, 2 rows, 25 positions per row
  • Contact Specifications: Beryllium copper material with gold finish (10.0µin thickness)
  • Mounting & Termination: Surface mount with solder termination
  • Environmental Ratings: Operating temperature range -55°C to 125°C, MSL 1
  • Compliance: ROHS3 compliant, EAR99 ECCN classification

Packaging format (Tape & Reel versus Tray) does not affect electrical or mechanical compatibility and is therefore not a substitution barrier.

Engineering Selection Recommendations

Both the HSEC8-125-01-L-DV-A-L2-TR and HSEC8-125-01-L-DV-A-L2 are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Both maintain ROHS3 compliance and carry the same environmental ratings and certifications (EAR99, HTSUS 8536.69.4040).

The primary distinction between these parts is packaging format: the main part is supplied in Tape & Reel format while the substitute is supplied in Tray format. This difference does not affect connector performance, pin configuration, or board-level compatibility.

The substitute part includes an additional Locking Ramp feature not specified in the main part. This feature provides enhanced mechanical retention and does not create incompatibility with applications designed for the base connector.

Selection between these parts should be based on packaging requirements, inventory availability, and supply chain logistics rather than electrical or mechanical considerations.

Frequently Asked Questions (FAQ)

Q: Are HSEC8-125-01-L-DV-A-L2-TR and HSEC8-125-01-L-DV-A-L2 electrically identical?

A: Yes. Both connectors have identical electrical specifications: 50 positions, female gender, 0.031" pitch, beryllium copper contacts with gold finish, and -55°C to 125°C operating temperature range.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging is used for automated assembly processes, while Tray packaging is used for manual handling or alternative assembly methods. The connector itself is identical; only the packaging format differs.

Q: Does the Locking Ramp feature on the substitute part affect compatibility?

A: No. The Locking Ramp is an additional mechanical feature that enhances retention. It does not alter the connector's electrical performance or pin layout and is fully compatible with applications designed for the base HSEC8-125 connector.

Q: Can I use HSEC8-125-01-L-DV-A-L2 in place of HSEC8-125-01-L-DV-A-L2-TR?

A: Yes, provided your assembly process can accommodate Tray packaging instead of Tape & Reel format. The connectors are electrically and mechanically equivalent.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HSEC8-125-01-L-DV-A-L2-TR and HSEC8-125-01-L-DV-A-L2 are ROHS3 compliant with MSL 1 rating and unlimited moisture sensitivity.

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

A: Both connectors are designed for 0.062" (1.57mm) card thickness. This specification must be matched in your PCB design for proper connector engagement.
