Molex 0382111209 Equivalent & Substitute Parts

Part Overview

The Molex 0382111209 is a 9-circuit barrier block connector with 0.563" (14.30mm) pitch, rated for 30A at 300V. This component features solder tab termination and dual-wall barrier construction with a phenolic insulation body. The part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring this connector class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0382111209 is determined by the following critical parameters:

• Electrical Compatibility: Matching current rating (30A), voltage rating (300V), and wire gauge acceptance range
• Physical Compatibility: Identical number of circuits (9), pitch spacing (0.563"), number of rows (2), and mounting configuration (Chassis, Panel)
• Mechanical Compatibility: Dual-wall barrier construction and flange feature presence
• Termination Type: Top termination method must accommodate the application requirements

The TE Connectivity AMP Connectors part 1546310-9 qualifies as a direct substitute based on these parameters, with the primary difference being termination method (screws vs. solder tabs) and wire gauge range expansion (10-22 AWG vs. 10-18 AWG).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1546310-9 is the qualified substitute for the obsolete Molex 0382111209. Selection between these parts depends on termination method requirements:

Molex 0382111209 (Solder Tab Termination): Select when PCB-mounted solder connections are required. Product status is obsolete; inventory availability is limited to existing stock.

TE Connectivity 1546310-9 (Screw Termination): Select for applications requiring field-replaceable wire connections via terminal screws. This part is active in production with established supply chain availability. Wire gauge range (10-22 AWG) provides broader conductor accommodation than the original part (10-18 AWG). Both parts maintain identical electrical ratings, physical dimensions, and safety certifications (UL94 V-0, RoHS compliance, EAR99 export classification).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1546310-9 directly replace the Molex 0382111209 in existing designs?

A: Direct mechanical and electrical replacement is possible when the application accommodates screw termination instead of solder tabs. All electrical parameters (30A, 300V), physical dimensions (9 circuits, 0.563" pitch), and safety ratings are identical. PCB layout modifications may be required if the original design uses solder pad patterns specific to solder tab termination.

Q: What is the primary difference between these two parts?

A: The main difference is termination method. The Molex part uses solder tabs for permanent PCB attachment, while the TE Connectivity part uses terminal screws for removable wire connections. The TE part also accepts wire gauges from 10-22 AWG compared to the Molex specification of 10-18 AWG.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and meet RoHS requirements. The Molex part is ROHS3 compliant, while the TE part is RoHS compliant. Both share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications for export and tariff purposes.

Q: What is the operating temperature range for each part?

A: The Molex 0382111209 operates to 150°C. The TE Connectivity 1546310-9 operates from -40°C to 120°C. Application thermal requirements must be evaluated against these specifications.

Q: Are both parts available in the same packaging?

A: The Molex part is supplied in standard packaging (packaging type not specified). The TE Connectivity part is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.
