Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-316LF are qualified based on the following critical parameters:

• Connector Type & Contact Configuration: All substitutes must be receptacle connectors with female socket contacts
• Position Count & Pitch: 16 positions at 0.079" (2.00mm) pitch with 2-row configuration
• Mounting & Termination: Surface mount with solder termination
• Fastening Method: Push-pull fastening mechanism
• Operating Temperature Range: -55°C ~ 125°C minimum
• Contact Material & Finish: Phosphor bronze with gold mating surface
• Compliance: RoHS and REACH compliance status

The four substitute parts (CLT-108-02-F-D-K-TR, CLT-108-02-G-D, CLT-108-02-L-D, and TLE-108-01-G-DV-A-K-TR) meet these core electrical and mechanical requirements. Variations in insulation material (LCP vs. Plastic), contact finish thickness, current rating, and packaging format do not prevent functional substitution when mechanical and electrical compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core electrical and mechanical requirements of the 55508-316LF. Selection among substitutes should be based on:

CLT-108-02-F-D-K-TR: Samtec CLT series with highest current rating (4.1A per contact) and tape & reel packaging. ROHS3 compliant. Suitable for high-current applications requiring automated assembly.

CLT-108-02-G-D: Samtec CLT series with gold post finish and tube packaging. ROHS3 compliant. Provides enhanced contact durability with dual gold plating (mating and post surfaces).

CLT-108-02-L-D: Samtec CLT series with tin post finish and tube packaging. ROHS3 compliant. Standard configuration with lower cost profile compared to gold post variant.

TLE-108-01-G-DV-A-K-TR: Samtec TLE series pass-through receptacle with board guide feature and tape & reel packaging. ROHS3 compliant. Supports board-to-board or cable applications with increased insulation height (0.177" vs. 0.083"). Highest inventory availability (3,212 units).

All substitutes are ROHS3 compliant and maintain MSL 1 rating. The primary differentiators are insulation material composition (LCP vs. Plastic), connector style (standard vs. pass-through), and packaging format (tube vs. tape & reel).

Frequently Asked Questions (FAQ)

Q: Can CLT-108-02-F-D-K-TR replace 55508-316LF in existing designs? A: Yes. Both connectors share identical pitch (0.079"), position count (16), row configuration (2), mounting type (surface mount), and operating temperature range (-55°C ~ 125°C). The primary difference is insulation material (LCP vs. Plastic) and higher current rating (4.1A vs. 2A per contact). Mechanical and electrical compatibility is maintained.

Q: What is the difference between CLT-108-02-G-D and CLT-108-02-L-D? A: Both are Samtec CLT series with identical electrical and mechanical specifications. The difference is contact finish on the post: CLT-108-02-G-D has gold finish (3.00µin thickness) while CLT-108-02-L-D has tin finish. Both are packaged in tubes and are ROHS3 compliant.

Q: Why does TLE-108-01-G-DV-A-K-TR have a different insulation height? A: The TLE-108-01-G-DV-A-K-TR is a pass-through receptacle connector designed for board-to-board or cable applications. The increased insulation height (0.177" vs. 0.083") accommodates the pass-through design and board guide feature. This does not affect substitution compatibility if the application supports the larger form factor.

Q: Are all substitutes RoHS compliant? A: Yes. The main part (55508-316LF) is RoHS Compliant. All four substitutes are ROHS3 Compliant, which represents a more recent RoHS standard iteration and maintains full compliance with RoHS requirements.

Q: What packaging options are available? A: The 55508-316LF is supplied in tube packaging. Substitutes offer both tube (CLT-108-02-G-D, CLT-108-02-L-D) and tape & reel (CLT-108-02-F-D-K-TR, TLE-108-01-G-DV-A-K-TR) options. Tape & reel packaging is suitable for automated assembly processes.

Q: Can I use these substitutes interchangeably on the same PCB? A: Mechanical and electrical interchangeability is maintained across all substitutes for the core connector function. However, the TLE-108-01-G-DV-A-K-TR pass-through design and increased insulation height may require PCB layout verification. Consult connector datasheets for specific footprint and clearance requirements.
