GDLX-S-66 Equivalent & Substitute Parts

Part Overview

The GDLX-S-66 is an active modular jack connector manufactured by Kycon, Inc., designed for 6p6c (RJ11, RJ12, RJ14, RJ25) applications. This shielded, right-angle through-hole connector features solder termination and board lock functionality. The part is RoHS compliant and operates across the industrial temperature range of -40°C to 85°C. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GDLX-S-66 are qualified based on the following critical parameters:

• Connector Type & Contact Configuration: Jack connector with 6p6c contact arrangement
• Mechanical Interface: Through-hole mounting with 90° right-angle orientation
• Electrical Interface: Solder termination with shielded construction
• Material Specifications: Phosphor bronze contacts with gold finish; PBT housing
• Environmental Compliance: RoHS compliance and operating temperature range of -40°C to 85°C
• Functional Features: Board lock capability and shielded design

The substitute part 5555140-1 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Additional features present in the substitute (EMI finger, panel stops, Cat3 rating) represent functional enhancements that do not preclude substitution in applications requiring the base electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the GDLX-S-66 and 5555140-1 are active products with RoHS compliance and identical export classifications (EAR99). Selection between these parts should be based on:

• Inventory Availability: GDLX-S-66 has 1054 units in stock; 5555140-1 has 3400 units in stock
• Compliance Requirements: Both parts satisfy RoHS and MSL 1 requirements
• Enhanced Features: The 5555140-1 includes EMI finger shielding and panel stops, which may provide additional performance in noise-sensitive applications but are not required for basic 6p6c jack functionality
• Manufacturer Preference: Selection may depend on established supplier relationships or design validation history with either Kycon or TE Connectivity

Frequently Asked Questions (FAQ)

Q: Can 5555140-1 be used as a direct replacement for GDLX-S-66?

A: Yes. Both connectors share identical contact configurations (6p6c), mounting methods (through-hole solder), orientations (90° right-angle), and operating temperature ranges (-40°C to 85°C). The EMI finger and panel stops on the 5555140-1 are supplementary features that do not affect basic substitution compatibility.

Q: What is the difference between the shielding specifications?

A: The GDLX-S-66 specifies shielded construction. The 5555140-1 specifies shielded construction with an EMI finger, which provides enhanced electromagnetic interference rejection. Both meet shielded connector requirements.

Q: Are there any packaging or handling differences?

A: Both parts are supplied in trays with MSL 1 (Unlimited) moisture sensitivity, indicating no special storage or handling requirements beyond standard component practices.

Q: Do both parts support the same RJ standards?

A: Yes. Both connectors support 6p6c contact arrangements compatible with RJ11, RJ12, RJ14, and RJ25 standards.

Q: What are the export compliance implications?

A: Both parts are classified as EAR99 and share the same HTSUS code (8536.69.4040), indicating equivalent export control treatment.
