TE Connectivity AMP Connectors 2064938-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2064938-1 is a fiber optic plug connector with LC simplex configuration designed for multimode applications. This connector features a beige polyether imide housing with zirconia ferrule, latch lock fastening, and protective cap with strain relief. The product is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2064938-1 is based on the following critical parameters that define functional compatibility:

Connector Interface Compatibility:

• Connector style (LC) and connector type (plug) must remain consistent for mechanical mating with existing receptacles
• Simplex configuration is required to maintain single-fiber transmission architecture

Operational Mode Consideration: The main part operates in multimode, while the identified substitute operates in singlemode. This represents a functional difference in fiber transmission capability. Both configurations utilize LC simplex plug connectors with free hanging in-line mounting and maintain compatibility with the LC connector interface standard.

Physical and Material Specifications:

• Cable diameter tolerance and ferrule material composition affect insertion loss and mechanical durability
• Housing and ferrule materials influence temperature stability and environmental performance
• Fastening mechanism (latch lock versus snap-in) affects connector retention characteristics

Compliance and Regulatory Status:

• Both parts maintain ROHS3 compliance and MSL 1 rating
• The substitute part carries active product status with defined REACH and ECCN classifications

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 2064938-1 is classified as obsolete. The Molex 1063975301 maintains active product status with defined regulatory classifications (REACH Unaffected, ECCN EAR99), ensuring continued availability and manufacturer support.

Compliance and Regulatory Alignment: Both parts achieve ROHS3 compliance and MSL 1 rating. The substitute part provides explicit REACH status documentation, whereas the original part carries vendor-undefined REACH status. This clarity supports regulatory compliance documentation requirements.

Connector Interface Standardization: Both parts utilize LC simplex plug connectors with free hanging in-line mounting, ensuring mechanical compatibility with existing LC receptacle infrastructure. The LC connector interface standard defines mating geometry independent of fiber mode or cable diameter variations.

Operational Mode Differences: Selection between multimode and singlemode operation depends on system architecture requirements. The original part supports multimode transmission; the substitute supports singlemode transmission. These represent distinct fiber optic transmission standards and cannot be interchanged without system-level evaluation.

Physical Parameter Variations: Cable diameter differs between parts (0.9mm versus 2.0mm), and fastening mechanisms vary (latch lock versus snap-in). These differences affect installation procedures and mechanical retention characteristics but do not prevent LC connector interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1063975301 directly replace the TE Connectivity 2064938-1 in existing installations?

A: Both parts share LC simplex plug connector configuration with free hanging in-line mounting, enabling mechanical mating with LC receptacles. However, the substitute operates in singlemode while the original operates in multimode. System compatibility depends on whether the installed fiber infrastructure and transmission equipment support singlemode operation. Cable diameter differences (0.9mm versus 2.0mm) and fastening mechanism variations (latch lock versus snap-in) require physical installation assessment.

Q: What are the key parameters that define substitution eligibility for LC simplex fiber optic connectors?

A: Substitution eligibility is determined by: connector style (LC), connector type (plug), simplex configuration, mounting type (free hanging in-line), and compliance certifications (ROHS3, MSL rating). Fiber transmission mode (multimode versus singlemode), cable diameter, ferrule material, and fastening mechanism represent functional variations that may or may not be compatible depending on system requirements.

Q: Why does the substitute part have a different cable diameter specification?

A: Cable diameter is specified by the connector design and is not a substitutable parameter. The TE Connectivity 2064938-1 accommodates 0.9mm cable diameter; the Molex 1063975301 accommodates 2.0mm cable diameter. Cable diameter selection is determined by the installed fiber optic cable specification and cannot be altered without changing the cable assembly.

Q: Are there compliance differences between the original and substitute parts?

A: Both parts achieve ROHS3 compliance and MSL 1 rating. The substitute part provides explicit REACH Unaffected status and ECCN EAR99 classification, whereas the original part carries vendor-undefined REACH status. For regulatory documentation purposes, the substitute part offers clearer compliance classification.

Q: What is the significance of the fastening type difference (latch lock versus snap-in)?

A: Fastening type affects connector retention and mating procedure. Latch lock fastening uses a mechanical latch mechanism for positive retention; snap-in fastening uses a spring-loaded retention mechanism. These represent different mechanical engagement methods and require different installation and removal procedures. System design determines which fastening type is appropriate.

Q: How does ferrule material affect connector performance?

A: Ferrule material influences mechanical durability, thermal stability, and insertion loss characteristics. The original part uses zirconia ferrule; the substitute uses ceramic ferrule. Both materials are standard in fiber optic connector applications. Material selection affects long-term performance under specific environmental and thermal conditions.
