Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 5406566-1 qualifies as a substitute for the Molex 0441500021 based on the following critical parameters:

Electrical Equivalence: Both parts maintain identical contact count (8p8c), connector type (jack), termination method (solder), shielding configuration (shielded with EMI finger), and Cat5 rating.

Mechanical Compatibility: Both parts feature 90° right-angle orientation, through-hole mounting, two ports, single row configuration, and identical operating temperature range (-40°C ~ 85°C).

Material Specifications: Both use phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness and polyamide (PA) nylon housing.

Regulatory Compliance: Both parts maintain RoHS compliance and EAR99 ECCN classification with identical HTSUS code 8536.69.4040.

The primary difference is the board-level feature: the Molex part includes board lock functionality while the TE Connectivity part includes board guide functionality. Both features serve mechanical retention purposes and do not affect electrical performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0441500021 and TE Connectivity 5406566-1 are active production parts with full RoHS compliance and identical regulatory classification. Selection between these parts should be based on board-level mechanical requirements: the Molex part provides board lock retention, while the TE Connectivity part provides board guide alignment. Both parts satisfy identical electrical, thermal, and environmental specifications for Cat5 Ethernet applications.

The TE Connectivity 5406566-1 offers higher current inventory availability (2724 units versus 1005 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0441500021 and TE Connectivity 5406566-1 pin-compatible?

A: Yes. Both parts feature identical 8p8c (RJ45) contact configurations with solder termination, phosphor bronze contacts with gold finish, and equivalent electrical ratings for Cat5 applications.

Q: What is the difference between board lock and board guide features?

A: Board lock provides mechanical retention by locking the connector to the PCB after insertion. Board guide provides alignment guidance during insertion. Both serve mechanical mounting purposes and do not affect electrical performance or signal integrity.

Q: Can these connectors be used interchangeably in existing designs?

A: Electrical and thermal interchangeability is confirmed. Mechanical interchangeability depends on PCB design: if the design accommodates board lock features, the Molex part is suitable; if the design accommodates board guide features, the TE Connectivity part is suitable. Housing material composition differs slightly (Molex includes glass-filled nylon; TE Connectivity uses standard nylon), which may affect mechanical properties in specific applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are RoHS compliant and classified as EAR99 for export control purposes. The Molex part carries ROHS3 certification; the TE Connectivity part carries standard RoHS certification. Both maintain identical HTSUS classification.

Q: What is the operating temperature range for both connectors?

A: Both parts operate across the identical temperature range of -40°C to 85°C, suitable for industrial and commercial networking applications.
