55508-330LF Equivalent & Substitute Parts

Part Overview

The 55508-330LF is a 30-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) in the Minitek® 2.00mm series. This surface mount connector features female socket contacts with gold mating finish, designed for board-to-board applications in general purpose, industrial, and medical environments. The part is currently active in production with 1129 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability, packaging preferences, or design flexibility within the allowed parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the 55508-330LF are qualified based on the following critical parameters that must remain constant:

30-position receptacle connector configuration
0.079" (2.00mm) mating pitch and row spacing
2-row arrangement
Female socket contact type
Surface mount solder termination
Push-pull fastening mechanism
Gold mating contact finish
Operating temperature range of -55°C ~ 125°C
Moisture sensitivity level 1

The substitute parts identified are from Samtec Inc. in the TLE series. These parts maintain all critical electrical and mechanical parameters while offering alternative packaging options (Tube versus Tape & Reel) and enhanced current rating capability (3.2A per contact versus 2A).

Engineering Selection Recommendations

All three parts maintain active product status and meet the core electrical and mechanical requirements for 30-position, 2.00mm pitch board-to-board rectangular connector applications. The Samtec TLE series substitutes offer higher current rating capability (3.2A per contact) compared to the Amphenol ICC 55508-330LF (2A), providing additional design margin for applications requiring higher current density.

Selection between TLE-115-01-G-DV-A-K (Tube packaging) and TLE-115-01-G-DV-A-K-TR (Tape & Reel packaging) depends on assembly process requirements. The Tape & Reel variant (TLE-115-01-G-DV-A-K-TR) carries REACH Unaffected status, while the Tube variant maintains REACH Affected status. Both Samtec parts are ROHS3 compliant, exceeding the RoHS compliance of the original part.

Frequently Asked Questions (FAQ)

Q: Can TLE-115-01-G-DV-A-K and TLE-115-01-G-DV-A-K-TR be used interchangeably with 55508-330LF?

A: Yes, both Samtec parts are electrically and mechanically equivalent substitutes. The difference is packaging format: Tube versus Tape & Reel. Component functionality and mating characteristics are identical.

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

A: Tube packaging (TLE-115-01-G-DV-A-K) is suitable for manual handling and lower-volume assembly. Tape & Reel packaging (TLE-115-01-G-DV-A-K-TR) is optimized for automated pick-and-place assembly equipment. Select based on your manufacturing process.

Q: Does the higher current rating of the Samtec parts affect compatibility?

A: No. The 3.2A per contact rating of the Samtec TLE series is a design enhancement that provides additional capacity. Applications designed for 2A operation remain fully compatible.

Q: Are there differences in contact finish thickness?

A: Yes. The 55508-330LF has 15.0µin (0.38µm) gold mating finish, while both Samtec substitutes have 10.0µin (0.25µm). Both finishes meet the functional requirements for gold-plated mating surfaces in this connector category.

Q: What is the significance of REACH Unaffected status for TLE-115-01-G-DV-A-K-TR?

A: REACH Unaffected status indicates the Tape & Reel variant does not contain substances of very high concern (SVHC) listed under REACH regulations. This may simplify compliance documentation for certain supply chain requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The 55508-330LF is RoHS Compliant. Both Samtec substitutes are ROHS3 Compliant, which represents an updated compliance standard.
