Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55508-320LF is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 20
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C

The Samtec Inc. TLE-110-01-G-DV-A-P-TR meets all critical substitution parameters. Both connectors share identical mechanical pitch, row configuration, mounting method, and operating temperature range. Both feature gold-plated mating contacts, push-pull fastening, and solder termination. The TLE-110-01-G-DV-A-P-TR is classified as a Pass Through receptacle variant, which maintains functional compatibility for board-to-board interconnection while offering enhanced current capacity per contact.

Parameter Comparison

Engineering Selection Recommendations

Both the 55508-320LF and TLE-110-01-G-DV-A-P-TR are Active status products with full RoHS compliance. The 55508-320LF carries RoHS Compliant certification, while the TLE-110-01-G-DV-A-P-TR meets ROHS3 Compliant standards. Both connectors are REACH Affected and classified under ECCN EAR99.

The TLE-110-01-G-DV-A-P-TR offers increased current capacity at 3.2A per contact compared to the 55508-320LF at 2A, and features Liquid Crystal Polymer insulation material versus standard plastic. The TLE variant includes board guide and pick-and-place features. The insulation height difference (0.177" vs 0.091") and contact finish thickness variation (10.0µin vs 15.0µin) must be evaluated against specific PCB layout and mating interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLE-110-01-G-DV-A-P-TR directly replace the 55508-320LF in existing designs?

A: Direct mechanical and electrical substitution is supported based on matching pitch (0.079"), position count (20), row configuration (2 rows), mounting type (surface mount), and operating temperature range (-55°C to 125°C). However, the increased insulation height (0.177" vs 0.091") and higher current rating (3.2A vs 2A) require verification against PCB layout constraints and circuit requirements.

Q: What are the key differences in contact finish specifications?

A: Both connectors feature gold-plated mating contacts. The 55508-320LF specifies 15.0µin (0.38µm) thickness, while the TLE-110-01-G-DV-A-P-TR specifies 10.0µin (0.25µm). Both thicknesses meet industry standards for gold plating on connector contacts and maintain functional compatibility.

Q: How do packaging formats affect component procurement?

A: The 55508-320LF is supplied in Tube packaging, while the TLE-110-01-G-DV-A-P-TR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly processes, whereas Tube packaging is suitable for manual handling and lower-volume applications. Procurement and assembly process requirements should guide packaging selection.

Q: Are both connectors suitable for medical applications?

A: The 55508-320LF explicitly lists medical applications in its specification. The TLE-110-01-G-DV-A-P-TR does not specify application categories in the provided data. Medical application suitability must be confirmed through the manufacturer's documentation and compliance certifications for the TLE variant.

Q: What is the significance of the Pass Through connector designation?

A: The TLE-110-01-G-DV-A-P-TR is designated as a Pass Through receptacle, indicating it supports both board-to-board and cable interconnection configurations. The 55508-320LF is specified for board-to-board style only. This expanded connectivity option in the TLE variant does not preclude its use in board-to-board applications.
