Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878315541 and Samtec LTMM-104-02-F-D maintain active product status and full compliance with ROHS3 regulations and REACH requirements. Selection between these parts should be based on:

Availability and Lead Time: Current inventory levels indicate 1022 units for the Molex part and 1386 units for the Samtec part, supporting procurement flexibility.

Series Compatibility: The Molex part operates within the Milli-Grid 87831 series, while the Samtec part belongs to the Flex Stack LTMM series. Both series support the specified electrical and mechanical parameters.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring equivalent export and tariff treatment.

Mechanical Differences: Minor variations exist in insulation height (Molex: 0.252" vs. Samtec: 0.190") and contact length specifications. These differences do not affect substitution compatibility for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec LTMM-104-02-F-D directly replace the Molex 0878315541 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), row spacing (2.00mm), number of positions (8), mounting type (through-hole), and shrouding configuration (4-wall). Electrical ratings and operating temperature ranges are equivalent.

Q: What are the key differences between these two connector models?

A: The primary differences are insulation material (Molex uses glass-filled polyamide; Samtec uses liquid crystal polymer), insulation height (Molex: 0.252"; Samtec: 0.190"), and fastening type (Molex uses latch holder; Samtec uses push-pull). These differences do not affect electrical compatibility or PCB mounting.

Q: Are both parts suitable for automotive applications?

A: The Molex 0878315541 explicitly lists automotive applications. The Samtec LTMM-104-02-F-D does not specify applications in the provided data. Verify application suitability with the manufacturer for automotive-specific requirements.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry identical HTSUS tariff classification (8536.69.4040).

Q: What is the current rating difference, and does it matter?

A: The Molex part specifies 2A current rating and 125V voltage rating. The Samtec part does not provide current or voltage ratings in the available data. For applications requiring specific current or voltage verification, contact the manufacturer directly.

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

A: Yes, provided the application does not depend on specific features unique to either connector (such as the latch holder fastening in the Molex part or the push-pull fastening in the Samtec part). Verify mechanical clearances due to the 0.062" difference in insulation height.
