Molex 0878312419 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0878312419 is an active rectangular connector header designed for through-hole mounting applications. This shrouded 24-position connector with 2.00mm pitch serves board-to-board and cable interconnection requirements across automotive, general purpose, and telecommunications sectors. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878312419 is determined by the following critical parameters:

• Connector Configuration: 24 positions, 2 rows, 0.079" (2.00mm) pitch mating and row spacing
• Mounting and Termination: Through-hole solder termination
• Shrouding: 4-wall shrouded design with keying slot
• Electrical Performance: Minimum 2A current rating and 125V voltage rating
• Environmental Compliance: ROHS3 compliance and MSL 1 rating
• Operating Temperature: Minimum -55°C to 105°C range

The Samtec Inc. LTMM-112-02-G-D meets these core substitution criteria through matching connector configuration, mounting type, shrouding design, and compliance certifications. Both parts maintain identical pitch specifications, position count, and row configuration, enabling direct mechanical and electrical interchange in applications where the specified parameters are met.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878312419 and Samtec LTMM-112-02-G-D maintain active product status with full ROHS3 compliance and REACH unaffected certification. The Samtec substitute provides an extended operating temperature range of -55°C to 125°C compared to the Molex specification of -55°C to 105°C, offering additional thermal margin in applications requiring higher temperature performance. Both connectors share identical electrical and mechanical interface specifications, enabling direct substitution in board-to-board and cable interconnection applications. Selection between these parts should be based on availability, lead time requirements, and specific application temperature demands within the stated operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the Samtec LTMM-112-02-G-D directly replace the Molex 0878312419 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (24), row configuration (2 rows), shrouding design (4-wall), and termination method (solder). The mechanical and electrical interfaces are compatible for direct board-level substitution.

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

A: The primary differences are the fastening type (Molex uses Latch Holder; Samtec uses Push-Pull), insulation material (Molex uses glass-filled polyamide; Samtec uses liquid crystal polymer), and operating temperature range (Samtec extends to 125°C versus Molex 105°C). Contact dimensions and insulation heights also differ slightly.

Q: Are both parts suitable for automotive applications?

A: The Molex 0878312419 is specified for automotive applications. The Samtec LTMM-112-02-G-D does not list specific applications in the provided data. Application suitability should be confirmed against specific automotive qualification requirements.

Q: What is the significance of the different fastening types?

A: The Molex connector uses a Latch Holder fastening mechanism, while the Samtec uses Push-Pull fastening. These represent different mating and unmating interface designs. Compatibility depends on the mating connector design in the application.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both connectors are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8536.69.4040). Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
