Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010977346 and TE Connectivity 6-146253-7 are Active product status connectors with full ROHS3 compliance and identical regulatory classifications (ECCN EAR99, HTSUS 8536.69.4040). Both connectors meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling requirements during storage or assembly.

The TE Connectivity 6-146253-7 provides documented operating temperature range (-65°C ~ 105°C) and current rating (3A), whereas the Molex 0010977346 does not specify these parameters in the provided data. Minor dimensional variations exist in contact post length (0.110" versus 0.125") and overall contact length (0.520" versus 0.533"), with the TE Connectivity part exhibiting slightly thicker gold plating on mating contacts (30.0µin versus 15.0µin).

Selection between these parts should be based on application-specific requirements, inventory availability, and design validation for the noted dimensional and plating differences.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0010977346 and TE Connectivity 6-146253-7 fully interchangeable?

A: Both connectors share identical critical parameters including 34-position, 2-row configuration, 0.100" (2.54mm) pitch, male pin contacts, gold-plated mating surfaces, and through-hole solder termination. Minor dimensional variations in contact post length and overall contact length exist and should be evaluated for specific PCB layout and mating interface requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching connector type (Header, Breakaway), contact type (Male Pin), position count (34), row count (2), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), mounting type (Through Hole), termination method (Solder), fastening type (Push-Pull), contact finishes (Gold mating, Tin post), insulation material (LCP), flammability rating (UL94 V-0), RoHS compliance status, and MSL rating.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the Molex 0010977346 and TE Connectivity 6-146253-7 are ROHS3 compliant, carry EAR99 ECCN classification, share the same HTSUS code (8536.69.4040), and meet UL94 V-0 flammability requirements. Both are classified as MSL 1 (Unlimited), requiring no special moisture control during handling or storage.

Q: What is the significance of the contact finish thickness difference?

A: The TE Connectivity 6-146253-7 features thicker gold plating on mating contacts (30.0µin versus 15.0µin on the Molex part). Thicker plating generally provides enhanced wear resistance and contact durability over extended mating cycles, though both thicknesses meet standard connector performance requirements.

Q: Are there any dimensional considerations for PCB layout?

A: Contact post length differs between the two parts (Molex 0.110" versus TE Connectivity 0.125"), and overall contact length varies (Molex 0.520" versus TE Connectivity 0.533"). These differences may affect PCB hole depth, solder joint formation, and board-to-board spacing. Design validation is recommended when substituting between these parts.

Q: What inventory status should be considered for procurement?

A: The Molex 0010977346 has 892 pieces in stock, while the TE Connectivity 6-146253-7 has 2,647 pieces available. Inventory levels may influence procurement decisions for immediate availability or long-term supply chain planning.
