Molex 0039301062 Equivalent & Substitute Parts

Part Overview

The Molex 0039301062 is an active rectangular connector header designed for through-hole, right-angle board-to-cable applications. This shrouded 6-position connector operates at 0.165" (4.20mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The component is widely used in general purpose, industrial, and telecommunications applications where reliable interconnection and mechanical stability are required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints necessitate qualified alternatives.

Substitute Part Grouping Explanation

The Samtec Inc. IPBT-103-H1-T-D-RA qualifies as a substitute for the Molex 0039301062 based on the following critical parameters:

• Connector Configuration: Both parts are 6-position, 2-row headers with identical 0.165" (4.20mm) mating pitch and row spacing
• Mounting and Orientation: Both feature through-hole, right-angle mounting with shrouded 4-wall design
• Termination Method: Both use solder termination with locking ramp fastening
• Compliance: Both are ROHS3 compliant and UL94 V-0 rated
• Contact Type: Both employ male pin contacts with square contact geometry
• Electrical Ratings: Both support the same voltage and current operating ranges for general purpose applications

The substitution is valid for applications requiring equivalent mechanical and electrical performance within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0039301062 and Samtec IPBT-103-H1-T-D-RA are active products with equivalent regulatory compliance. Selection between these parts should be based on:

• Availability: The Molex part has 3158 units in stock; the Samtec substitute has 1303 units available
• Insulation Material: The Molex part uses polyamide (PA66/Nylon 6/6), while the Samtec part uses liquid crystal polymer (LCP). LCP offers superior thermal and chemical resistance
• Operating Temperature: The Samtec part specifies -55°C to 105°C operating range; the Molex part does not specify this parameter
• Contact Finish - Mating: The Molex part features gold plating (30.0µin thickness); the Samtec part uses tin plating. Gold provides superior corrosion resistance in demanding environments
• Voltage Rating: The Samtec part specifies 400VAC and 565VDC ratings; the Molex part does not specify voltage ratings

Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance for general purpose, industrial, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec IPBT-103-H1-T-D-RA directly replace the Molex 0039301062 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.165"), row spacing (0.165"), position count (6), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), and fastening mechanism (locking ramp). Mechanical and electrical compatibility is established for board-to-cable applications.

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

A: The primary differences are insulation material (polyamide versus liquid crystal polymer), contact finish on mating surfaces (gold versus tin), and specified operating temperature range (Samtec specifies -55°C to 105°C). The Samtec part also provides explicit voltage ratings (400VAC, 565VDC).

Q: Which part should be selected for high-reliability applications?

A: Selection depends on environmental requirements. The Molex part with gold-plated mating contacts offers superior corrosion resistance. The Samtec part with LCP insulation provides better thermal stability and chemical resistance. Both meet UL94 V-0 flammability standards.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The Molex part has higher current inventory (3158 units) compared to the Samtec substitute (1303 units).

Q: Do both parts comply with RoHS and REACH regulations?

A: Yes. Both the Molex 0039301062 and Samtec IPBT-103-H1-T-D-RA are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and 8536.69.4040 HTSUS code.
