Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 503569-1 with the HellermannTyton FCST is based on alignment of the following critical parameters:

Matching Parameters:

• Connector Style: ST
• Connector Type: Plug
• Simplex/Duplex Configuration: Simplex
• Mode: Multimode
• Cable Diameter: 3.0mm
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Features: Dust Cap
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.70.0000

Differing Parameters:

• Housing Color: Black (503569-1) vs. Silver (FCST)
• Ferrule Material: Ceramic (503569-1) vs. Zirconia (FCST)
• Product Status: Obsolete (503569-1) vs. Active (FCST)
• RoHS Status: ROHS3 Compliant (503569-1) vs. RoHS Compliant (FCST)

The HellermannTyton FCST maintains functional equivalence through identical connector geometry, fastening mechanism, and fiber configuration while offering active product status and current compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The HellermannTyton FCST serves as a functional equivalent to the obsolete TE Connectivity 503569-1 for ST simplex multimode fiber optic applications. Selection of the FCST is supported by the following factors:

Product Status: The FCST maintains active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete 503569-1.

Compliance Certifications: Both connectors meet RoHS compliance requirements. The FCST carries current RoHS certification, while the 503569-1 carries ROHS3 compliance. Both connectors are classified as EAR99 for export control purposes.

Functional Compatibility: Identical connector geometry, bayonet lock fastening, and 3.0mm cable diameter specifications ensure mechanical and optical interface compatibility within ST simplex multimode fiber systems.

Material Considerations: The FCST employs zirconia ferrule material in place of the ceramic ferrule in the 503569-1. Both materials are standard in fiber optic connector applications and maintain compatibility with standard ST receptacles.

Packaging and Availability: The FCST is available in bulk packaging with 850 pieces in current inventory, compared to the 653 pieces of the obsolete 503569-1.

Frequently Asked Questions (FAQ)

Q: Can the HellermannTyton FCST directly replace the TE Connectivity 503569-1 in existing installations?

A: Yes. Both connectors share identical ST simplex connector geometry, bayonet lock fastening, and 3.0mm cable diameter specifications. The FCST will mate with standard ST receptacles designed for the 503569-1.

Q: What is the difference between ceramic and zirconia ferrule materials?

A: Both ceramic and zirconia are standard ferrule materials in fiber optic connectors. The FCST uses zirconia ferrule material while the 503569-1 uses ceramic. Both materials provide the mechanical and optical properties required for ST simplex multimode fiber applications.

Q: Does the housing color difference between black and silver affect connector function?

A: Housing color is a cosmetic and identification parameter. The color difference does not affect optical or mechanical performance. The silver housing of the FCST provides visual distinction from the black 503569-1 but maintains full functional equivalence.

Q: Are both connectors RoHS compliant?

A: Yes. The TE Connectivity 503569-1 carries ROHS3 compliance certification. The HellermannTyton FCST carries RoHS compliance certification. Both meet regulatory requirements for hazardous substance restrictions.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that the connector has no moisture sensitivity restrictions and requires no special handling, storage, or baking procedures prior to installation.

Q: Why is the 503569-1 classified as obsolete?

A: Obsolete status indicates that the TE Connectivity 503569-1 is no longer in active production. The HellermannTyton FCST provides an active alternative with equivalent specifications for continued system support.

Q: Are there any differences in the dust cap feature between the two connectors?

A: Both the 503569-1 and FCST include dust cap features. This feature provides protection for the connector interface when not in use.
