Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0878333421 are qualified based on the following critical parameters that determine functional interchangeability:

• Position Count & Pitch: All substitutes maintain 34 positions in 2 rows with 0.079" (2.00mm) mating pitch and row spacing
• Mounting Configuration: All substitutes feature through-hole, right-angle mounting with solder termination
• Shrouding & Contact Type: All substitutes maintain shrouded 4-wall design with male pin contacts
• Contact Finish: All substitutes provide gold-plated mating surfaces with tin-plated posts
• Compliance: All substitutes meet RoHS3 compliance and MSL 1 rating

The three qualified substitutes are manufactured by Amphenol ICC (FCI) and Samtec Inc., representing alternative sources for the same functional connector specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet the core electrical and mechanical requirements for interchangeability with the Molex 0878333421. Selection among substitutes should be based on the following factors:

Amphenol ICC 98464-G61-34LF (Minitek® 2.00mm Series): This substitute provides the highest inventory availability at 913 units and features GXT™ gold plating on mating contacts. The thermoplastic insulation material differs from the original polyamide specification. RoHS compliance is confirmed, though operating temperature range is not specified. Bulk packaging is provided.

Samtec LTMM-117-02-F-D-RA (Flex Stack Series): This substitute offers the highest inventory level at 1524 units and maintains phosphor bronze contact material matching the original specification. Operating temperature range of -55°C to 105°C is confirmed. Liquid crystal polymer insulation provides enhanced thermal and mechanical properties. Push-pull fastening differs from the latch holder design. ROHS3 compliance is confirmed. Tube packaging is provided.

Samtec LTMM-117-02-S-D-RA (Flex Stack Series): This substitute provides 1182 units in inventory and maintains identical electrical and mechanical specifications to the LTMM-117-02-F-D-RA variant, with confirmed ROHS3 compliance and -55°C to 105°C operating temperature range. Phosphor bronze contact material and liquid crystal polymer insulation match the original design intent. Push-pull fastening is employed. Tube packaging is provided.

Frequently Asked Questions (FAQ)

Q: Are these substitute parts mechanically compatible with the Molex 0878333421?

A: Yes. All substitute parts maintain identical mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), position count (34 in 2 rows), and right-angle through-hole mounting configuration. Physical board-level compatibility is ensured.

Q: What is the difference between the Samtec LTMM-117-02-F-D-RA and LTMM-117-02-S-D-RA variants?

A: Both Samtec variants maintain identical electrical and mechanical specifications, including phosphor bronze contacts, liquid crystal polymer insulation, -55°C to 105°C operating temperature, and push-pull fastening. The primary distinction is inventory availability, with the -S-D-RA variant providing 1182 units compared to 1524 units for the -F-D-RA variant.

Q: Does the fastening type difference (Latch Holder vs. Push-Pull) affect interchangeability?

A: Fastening type differences do not affect electrical interchangeability or board-level mating. However, mechanical engagement and disconnection procedures differ. The Molex original uses latch holder fastening, while Samtec substitutes employ push-pull fastening. Application-specific requirements should be evaluated.

Q: Are all substitutes RoHS compliant?

A: Yes. The Amphenol ICC 98464-G61-34LF is RoHS compliant. Both Samtec variants (LTMM-117-02-F-D-RA and LTMM-117-02-S-D-RA) are ROHS3 compliant. The original Molex 0878333421 is ROHS3 compliant.

Q: What is the difference in insulation material between the original and substitutes?

A: The Molex 0878333421 uses polyamide (PA) nylon with glass filling. The Amphenol ICC 98464-G61-34LF uses thermoplastic insulation. Both Samtec variants use liquid crystal polymer (LCP) insulation. All materials meet UL94 V-0 flammability requirements where specified.

Q: Which substitute offers the best inventory availability?

A: The Samtec LTMM-117-02-F-D-RA provides the highest inventory at 1524 units in stock, followed by the Samtec LTMM-117-02-S-D-RA at 1182 units and the Amphenol ICC 98464-G61-34LF at 913 units.

Q: Are the contact finish specifications identical across all parts?

A: All parts feature gold-plated mating surfaces and tin-plated posts. The Amphenol ICC variant specifies GXT™ gold plating technology. Contact finish thickness varies slightly: Molex and Amphenol specify 30.0µin (0.76µm) for mating surfaces, while Samtec specifies 3.00µin (0.076µm) for the LTMM-117-02-F-D-RA variant.
