Molex 1060100260 Fiber Optic ST Plug Connector - Equivalent & Substitute Parts

Part Overview

The Molex 1060100260 is a fiber optic plug connector featuring ST simplex configuration with 127µm cladding diameter, designed for multimode applications. This connector utilizes a bayonet lock fastening mechanism and includes dust cap and strain relief features. The product is classified as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity and support ongoing system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 1060100260 is determined by the following critical parameters:

• Connector Style & Type: Must be ST plug configuration to ensure mechanical and optical compatibility with existing mating receptacles
• Simplex Configuration: Single fiber channel requirement must be maintained
• Multimode Operation: Mode classification must remain consistent
• Fastening Mechanism: Bayonet lock fastening is required for proper mating interface
• Cable Diameter: 3.0mm cable diameter specification must be preserved
• Mounting Configuration: Free hanging in-line mounting type must be maintained
• Core Features: Dust cap and strain relief features are functional requirements

The TE Connectivity AMP Connectors part 503677-1 qualifies as a substitute based on matching all critical parameters. The fiber cladding diameter variance (125µm vs. 127µm) represents a minor specification difference within standard multimode fiber tolerances and does not preclude functional substitution in multimode applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 503677-1 is designated as the manufacturer-recommended substitute for the obsolete Molex 1060100260. Selection of this substitute is supported by the following factors:

• Product Status: The TE Connectivity part maintains active product status, ensuring ongoing availability and supply chain support
• Regulatory Compliance: Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent environmental handling requirements
• Functional Equivalence: Matching connector style, type, simplex configuration, multimode operation, fastening mechanism, and mounting type ensure direct functional replacement capability
• Certification Alignment: Both components are classified under HTSUS 8536.70.0000 and ECCN EAR99, maintaining consistent export and tariff classification

The ferrule material difference (zirconia to ceramic) and the specified mating cycle rating of 500 cycles for the TE Connectivity part represent documented performance characteristics of the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 503677-1 directly replace the Molex 1060100260 in existing installations?

A: Yes. Both connectors share identical ST plug simplex configuration, bayonet lock fastening, 3.0mm cable diameter, and free hanging in-line mounting type. The mechanical and optical interfaces are compatible with existing mating receptacles designed for ST simplex connectors.

Q: What is the significance of the fiber cladding diameter difference (127µm vs. 125µm)?

A: Both cladding diameters fall within standard multimode fiber specifications. The 2µm difference does not affect functional compatibility in multimode applications where both connectors operate within the same optical performance envelope.

Q: Are there differences in environmental handling between these two parts?

A: Both components carry identical MSL 1 (Unlimited) ratings, indicating equivalent moisture sensitivity levels and identical storage and handling requirements.

Q: What is the difference in ferrule material between the two connectors?

A: The Molex part uses zirconia ferrule material while the TE Connectivity substitute uses ceramic ferrule material. Both materials are standard in fiber optic connector applications and provide equivalent optical performance in multimode configurations.

Q: Does the TE Connectivity part include the same protective features?

A: Yes. Both connectors include dust cap and strain relief features as standard components.
