Molex 0349610383 MINI50 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The Molex 0349610383 is a MINI50 series rectangular connector header designed for through-hole, right-angle mounting applications. This 38-position connector features a 0.079" (2.00mm) pitch and is configured for board-to-cable/wire connections with solder termination. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and design requirements. Substitute parts must maintain electrical and mechanical compatibility while offering current product availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349610386 is the direct functional equivalent for the obsolete Molex 0349610383. Both components are manufactured by Molex within the same Mini50 34961 series and share identical electrical and mechanical specifications for mating pitch, position count, row configuration, voltage rating, and operating temperature range.

Product Status Consideration: The 0349610383 is classified as obsolete, while the 0349610386 maintains active product status with significantly higher inventory availability (2481 units versus 982 units). This status differential supports transition to the substitute part for new designs and ongoing procurement.

Compliance Alignment: Both parts maintain ROHS3 compliance, UL94 HB flammability rating, and EAR99 export classification. The substitute part carries REACH Unaffected status, providing additional regulatory clarity for international applications.

Material Enhancement: The substitute part features glass-filled Syndiotactic Polystyrene (SPS) insulation material compared to standard SPS in the main part. This material enhancement provides improved mechanical and thermal properties while maintaining all electrical performance parameters and operating temperature specifications.

Connector Architecture: The 0349610386 incorporates breakaway connector capability and expanded contact type designation (Male Blade; Male Pin) with contact length specification at mating interface (0.215" / 5.45mm), providing enhanced design flexibility without compromising core substitution compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349610386 be used as a direct replacement for the 0349610383 in existing designs?

A: Yes. Both connectors maintain identical mating pitch (0.079" / 2.00mm), position count (38), row configuration (3), mounting type (through-hole right-angle), and electrical ratings (14VDC, -40°C to 105°C). The substitute part is electrically and mechanically compatible for direct substitution in board-to-cable/wire applications.

Q: What is the significance of the glass-filled insulation material in the substitute part?

A: The glass-filled Syndiotactic Polystyrene (SPS) insulation in the 0349610386 provides enhanced mechanical strength and thermal stability compared to standard SPS. This material upgrade does not alter electrical performance or operating temperature specifications and is fully compatible with existing circuit designs.

Q: Are there packaging differences between the main part and substitute?

A: The main part (0349610383) packaging is listed as unspecified, while the substitute part (0349610386) is supplied in bulk packaging. Both parts are available as new original stock. Packaging format should be confirmed with procurement specifications for your application requirements.

Q: Does the breakaway connector feature in the substitute part affect compatibility?

A: No. The breakaway capability in the 0349610386 is an additional design feature that does not compromise compatibility with applications designed for the standard 0349610383. The core connector architecture, mating interface, and electrical specifications remain identical.

Q: What is the difference between the fastening types listed for each part?

A: The main part specifies Latch Lock fastening, while the substitute specifies Latch Holder fastening. Both fastening mechanisms provide secure mating retention within the MINI50 series connector system and are compatible with standard mating connectors designed for this series.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 0349610383 and 0349610386 are ROHS3 compliant with UL94 HB flammability rating. The substitute part carries additional REACH Unaffected status, confirming compliance with European chemical regulations for unrestricted use in international markets.

Q: Why is the substitute part recommended despite the main part having current inventory?

A: The main part is classified as obsolete, indicating discontinued production and limited future availability. The substitute part maintains active product status with higher inventory levels (2481 units), ensuring long-term supply chain reliability for new designs and production continuity.
