Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP 1985149-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Coupler
• Adapter configuration: LC Receptacle to LC Receptacle
• Duplex operation: Duplex
• Fiber mode: Singlemode
• Mounting method: Panel Mount with Snap-In capability
• Dust cap inclusion: Required
• Color: Blue
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Ferrule material: Ceramic or Zirconia (both acceptable for singlemode LC applications)
• Housing material: Polyphenylene Ether (PPE), Polystyrene (PS), or Polymer compositions
• Mounting flange design: Variations in panel mount flange geometry permitted
• Operating temperature range: Specification provided for active substitute

The Molex 1061261400 satisfies all mandatory parameters and represents a functionally equivalent active substitute for the obsolete TE Connectivity AMP component.

Engineering Selection Recommendations

The Molex 1061261400 is the appropriate substitute for the obsolete TE Connectivity AMP 1985149-1 based on the following engineering criteria:

Product Status Alignment: The TE Connectivity AMP 1985149-1 is classified as obsolete, while the Molex 1061261400 maintains active product status with current manufacturing and supply availability.

Compliance Certification: Both components achieve ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory alignment for applications requiring these certifications.

Functional Equivalence: The Molex substitute maintains identical connector configuration (LC Receptacle to LC Receptacle duplex), fiber mode (singlemode), and mounting methodology (panel mount, snap-in). These parameters define the core functional requirements for coupler operation.

Material Compatibility: Zirconia ferrule material in the Molex component provides functional equivalence to ceramic ferrules for singlemode LC applications. Both materials meet optical performance standards for this connector class.

Moisture and Environmental Ratings: Both components share MSL rating 1 (unlimited moisture sensitivity level), indicating equivalent handling and storage requirements.

The Molex 1061261400 provides direct functional replacement capability for the obsolete TE Connectivity AMP component without modification to installation procedures or system integration.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1061261400 directly replace the TE Connectivity AMP 1985149-1 in existing installations?

A: Yes. Both components share identical LC Receptacle-to-LC Receptacle duplex configuration, singlemode fiber mode, and panel mount snap-in installation methodology. The Molex component integrates into existing panel mount applications without modification.

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

A: Both ceramic and zirconia are acceptable ferrule materials for singlemode LC coupler applications. The Molex 1061261400 uses zirconia ferrules, while the TE Connectivity AMP 1985149-1 uses ceramic ferrules. Both materials provide equivalent optical performance for singlemode fiber coupling.

Q: Are there any differences in the mounting flange design between these two couplers?

A: The TE Connectivity AMP 1985149-1 specifies panel mount with snap-in installation. The Molex 1061261400 specifies panel mount with flange and snap-in installation. Both mounting methods accommodate standard panel mount applications with snap-in retention.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the TE Connectivity AMP 1985149-1 and Molex 1061261400 are ROHS3 compliant and achieve UL94 V-0 flammability rating. Both components share MSL rating 1 (unlimited), indicating identical moisture sensitivity handling requirements.

Q: What is the inventory status for the substitute part?

A: The Molex 1061261400 maintains active product status with 819 pieces of new original stock available. The TE Connectivity AMP 1985149-1 is obsolete with 879 pieces remaining in inventory.

Q: Are there any operating temperature considerations when substituting these components?

A: The Molex 1061261400 specifies operating temperature range of -40°C to 85°C. The TE Connectivity AMP 1985149-1 does not provide an operating temperature specification. The Molex component's specified range covers standard industrial and telecommunications operating environments.

Q: What packaging format is available for the Molex substitute?

A: The Molex 1061261400 is supplied in bulk packaging, compared to the TE Connectivity AMP 1985149-1 which does not specify packaging format. Bulk packaging accommodates both individual component selection and volume procurement requirements.
