Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 166648-4 is determined by strict alignment of the following core parameters: connector type (receptacle, female sockets), number of positions (48), pitch (0.200"/5.08mm), number of rows (3), style (F), mounting type (through hole), contact finish (gold), operating temperature range (-55°C to 125°C), material flammability rating (UL94 V-0), and regulatory compliance (RoHS3).

The identified substitute parts—HARTING 09062482848 and HARTING 09062486835—satisfy all mandatory electrical and mechanical parameters. Both substitutes maintain the 48-position configuration, 0.200" pitch, 3-row layout, style F designation, through-hole mounting, gold contact finish, and full operating temperature range. Both are RoHS3 compliant with MSL Level 1 rating and UL94 V-0 flammability classification. Variations in termination method (press-fit versus solder), insulation material composition, and level/class designation do not preclude substitution when the core functional parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both HARTING substitute parts maintain active production status and full RoHS3 compliance, ensuring regulatory alignment with the primary TE Connectivity 166648-4 component.

HARTING 09062482848 operates within the specified -55°C to 125°C temperature range and carries a 6A current rating specification. This part utilizes solder termination and polybutylene terephthalate (PBT) glass-filled insulation material. The level/class designation of 1 differs from the primary part's level/class 2, reflecting a variation in connector classification within the DIN 41612 series framework.

HARTING 09062486835 is designated for power applications within the 48-position configuration and employs solder termination with thermoplastic glass-filled insulation. This part carries level/class 2 designation, matching the primary component. Operating temperature range and current rating specifications are not provided for this variant.

Both substitutes are available in higher inventory quantities (1124 and 4304 units respectively) compared to the primary part (966 units), supporting supply chain flexibility. Selection between substitutes should account for termination method requirements (press-fit versus solder), insulation material compatibility with application environment, and power handling specifications where applicable.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09062482848 directly replace TE Connectivity 166648-4 in existing PCB designs?

A: Direct replacement is possible when the design accommodates solder termination in place of press-fit termination. The electrical and mechanical parameters—48 positions, 0.200" pitch, 3-row configuration, style F, through-hole mounting, and gold contact finish—are identical. The operating temperature range (-55°C to 125°C) and flammability rating (UL94 V-0) match the primary part. PCB layout and assembly process modifications may be required to accommodate the termination method change.

Q: What is the significance of the level/class designation difference between the primary part and HARTING 09062482848?

A: Level/class designation in DIN 41612 connectors indicates the connector's classification within the standard framework. The primary part carries level/class 2, while HARTING 09062482848 carries level/class 1. Both designations are valid within the DIN 41612 series and do not prevent functional substitution when all core electrical and mechanical parameters align. The specific application requirements should determine whether this classification difference impacts suitability.

Q: Is HARTING 09062486835 suitable for applications requiring the full -55°C to 125°C operating temperature range?

A: Operating temperature range specifications are not provided for HARTING 09062486835. When operating temperature range is a critical design parameter, HARTING 09062482848 is the preferred substitute, as it explicitly supports the -55°C to 125°C range matching the primary TE Connectivity part.

Q: What are the implications of the termination method difference between press-fit and solder?

A: Press-fit termination (primary part) and solder termination (both substitutes) represent different assembly approaches. Press-fit connections are inserted into plated through-holes without solder, while solder termination requires thermal reflow or wave soldering processes. The choice between these methods affects PCB design, assembly equipment requirements, and rework procedures. Both methods achieve equivalent electrical connectivity when properly executed.

Q: Are all three parts suitable for RoHS3-regulated applications?

A: Yes. The primary TE Connectivity 166648-4 and both HARTING substitutes carry ROHS3 Compliant status, confirming compliance with RoHS3 directive requirements. All three parts are suitable for applications subject to RoHS3 regulations.

Q: What inventory considerations should influence part selection?

A: The primary TE Connectivity 166648-4 has 966 units in stock. HARTING 09062482848 has 1124 units available, and HARTING 09062486835 has 4304 units available. Higher inventory levels for substitute parts may support extended production runs or reduce lead time risk. Inventory availability should be evaluated alongside termination method and specification requirements for the specific application.
