Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68046-308LF is determined by strict alignment of the following critical parameters:

• Connector Configuration: 16-position receptacle with 2 rows at 0.100" (2.54mm) pitch and row spacing
• Mounting and Termination: Surface mount with solder termination
• Contact Interface: Female socket contacts with gold mating finish
• Mechanical Compatibility: Push-pull fastening for board-to-board or cable connection
• Electrical Performance: Voltage rating and operating temperature range sufficient for the application

The substitute part SSM-108-L-DV-BE (Samtec Inc., Tiger Claw™ SSM series) meets these core substitution criteria. Both connectors share identical position count, pitch, row configuration, mounting type, contact gender, and fastening mechanism. Both are surface mount receptacles with solder termination and gold-plated mating contacts, enabling direct functional equivalence in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 68046-308LF and SSM-108-L-DV-BE are active production components with current RoHS compliance certifications. The 68046-308LF maintains RoHS Compliant status, while the SSM-108-L-DV-BE carries ROHS3 Compliant designation. Both components are MSL 1 rated and classified under identical ECCN and HTSUS codes, indicating equivalent regulatory and trade classification.

Selection between these parts should account for the following provided specifications:

• Operating Temperature Range: The 68046-308LF supports -65°C to 125°C, while the SSM-108-L-DV-BE operates from -55°C to 125°C. Applications requiring operation below -55°C require the 68046-308LF.
• Voltage Rating: The 68046-308LF is rated for 1000V, while the SSM-108-L-DV-BE is rated for 405VAC or 572VDC. Applications exceeding 572VDC require the 68046-308LF.
• Insulation Material: The 68046-308LF uses Polyphenylene Sulfide (PPS) glass-filled material; the SSM-108-L-DV-BE uses Liquid Crystal Polymer (LCP).
• Contact Finish Thickness: The 68046-308LF mating contact finish is 30.0µin (0.76µm); the SSM-108-L-DV-BE is 10.0µin (0.25µm).

Frequently Asked Questions (FAQ)

Q: Can SSM-108-L-DV-BE directly replace 68046-308LF in all applications?

A: Both connectors share identical position count, pitch, row configuration, mounting type, contact gender, and fastening mechanism. Direct substitution is possible when the application voltage does not exceed 572VDC and operating temperature remains above -55°C. Applications requiring 1000V rating or operation below -55°C must use the 68046-308LF.

Q: What is the difference between "Bottom Entry" and standard receptacle configurations?

A: The SSM-108-L-DV-BE is designated as "Bottom Entry," indicating the connector entry orientation. Both parts function as receptacles with identical electrical and mechanical interfaces for mating with complementary plug connectors.

Q: Are the insulation materials interchangeable?

A: The 68046-308LF uses Polyphenylene Sulfide (PPS) glass-filled material, while the SSM-108-L-DV-BE uses Liquid Crystal Polymer (LCP). Both materials are suitable for surface mount applications. Material selection depends on specific environmental and thermal requirements of the application.

Q: What does the contact finish thickness difference mean for reliability?

A: The 68046-308LF provides 30.0µin (0.76µm) gold plating on mating contacts compared to 10.0µin (0.25µm) on the SSM-108-L-DV-BE. Thicker plating generally provides extended contact life in high-cycle mating applications. For standard board-to-board connections with limited mating cycles, both thicknesses are functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The 68046-308LF is RoHS Compliant, and the SSM-108-L-DV-BE is ROHS3 Compliant. Both meet current RoHS requirements and are suitable for applications requiring RoHS certification.
