Substitute Part Grouping Explanation

Substitution of the 68046-314PLF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Connector type: Receptacle
Contact type: Female Socket
Number of positions: 28
Pitch - mating: 0.100" (2.54mm)
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Surface Mount
Style: Board to Board
Termination: Solder
Fastening type: Push-Pull
Contact finish - mating: Gold
Contact finish thickness - mating: 30.0µin (0.76µm)

The HLE-114-02-S-DV-TR from Samtec Inc. meets all mandatory matching parameters and qualifies as a direct substitute for the obsolete 68046-314PLF. Both connectors share identical mating pitch, position count, row configuration, and contact specifications, ensuring mechanical and electrical compatibility in board-to-board applications.

Engineering Selection Recommendations

The HLE-114-02-S-DV-TR is the recommended substitute for the obsolete 68046-314PLF based on the following factors:

Product Status: The 68046-314PLF is obsolete, while the HLE-114-02-S-DV-TR is active and in production. This ensures long-term availability and supply chain continuity for new designs and ongoing system support.

Compliance: The HLE-114-02-S-DV-TR is RoHS3 compliant, meeting current environmental and regulatory standards. Both connectors share MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent handling and storage requirements.

Electrical and Mechanical Compatibility: Both connectors meet identical mating pitch (0.100"), position count (28), row configuration (2 rows), and contact specifications. The gold-plated mating contacts with 30.0µin thickness ensure equivalent signal integrity and contact reliability.

Operating Conditions: The HLE-114-02-S-DV-TR operates across -55°C to 125°C, which covers the lower temperature range of the original part (-65°C to 125°C). For applications requiring operation below -55°C, thermal performance must be evaluated against specific system requirements.

Voltage Considerations: The 68046-314PLF is rated at 1000V, while the HLE-114-02-S-DV-TR is rated at 400VAC. For applications requiring the full 1000V rating, voltage compatibility must be confirmed before substitution.

Frequently Asked Questions (FAQ)

Q: Can the HLE-114-02-S-DV-TR directly replace the 68046-314PLF in existing designs?

A: Yes, for applications operating within the HLE-114-02-S-DV-TR specifications. Both connectors share identical mating pitch, position count, row spacing, and contact configuration. Verify that your application voltage requirements do not exceed 400VAC and operating temperature does not fall below -55°C.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete vs. active), insulation material (PPS glass-filled vs. LCP), insulation height (0.310" vs. 0.144"), contact material (phosphor bronze vs. beryllium copper), operating temperature range (-65°C to 125°C vs. -55°C to 125°C), and voltage rating (1000V vs. 400VAC).

Q: Are the physical dimensions compatible for PCB layout?

A: Both connectors use identical mating pitch (0.100") and row spacing (0.100"), ensuring compatible PCB footprints. However, the insulation height differs: 0.310" for the 68046-314PLF versus 0.144" for the HLE-114-02-S-DV-TR. Verify clearance requirements for your specific board design.

Q: What is the current rating for the HLE-114-02-S-DV-TR?

A: The HLE-114-02-S-DV-TR is rated at 4.1A per contact. Confirm this meets your application current requirements.

Q: Are both connectors RoHS compliant?

A: The HLE-114-02-S-DV-TR is RoHS3 compliant. RoHS status for the 68046-314PLF is not specified in the provided data.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
