Molex 0395326504 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Molex 0395326504 is a 4-position terminal block header with male pins, shrouded design, and 5.08mm pitch for right-angle through-hole mounting. This component is classified as Active and fully compliant with RoHS3 standards. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align with the original specification, enabling direct replacement in applications where the primary part is unavailable or when design flexibility permits alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Electrical Compatibility: Current rating (15 A UL), voltage rating (300 V UL), and contact material conductivity
• Mechanical Compatibility: 4-position configuration, 5.08mm pitch (or 5.00mm for 796644-4), right-angle orientation, through-hole mounting, and shrouded male pin design
• Thermal Compatibility: Operating temperature range sufficient for application requirements
• Material & Compliance: UL94 V-0 flammability rating, RoHS3 compliance, and polyamide housing
• Contact Finish & Material: Gold or tin plating; brass or copper alloy contacts

The three substitute parts (796638-4, 796639-4, 796644-4) from TE Connectivity AMP Connectors meet these criteria with documented equivalence in electrical performance and mechanical form factor. Pitch variation in 796644-4 (5.00mm vs. 5.08mm) represents a minor tolerance difference within industry standards for this component class.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and meet or exceed the electrical and thermal specifications of the Molex 0395326504. Selection among substitutes should be based on the following factors:

TE Connectivity 796638-4: Matches the original part in pitch (5.08mm), color (green), and housing material. Operating temperature extends to 110°C. Contact finish is tin rather than gold. RoHS3 compliant. Suitable for applications where extended thermal performance is beneficial.

TE Connectivity 796639-4: Identical electrical and mechanical specifications to 796638-4 with black housing color. RoHS compliant (vendor-defined REACH status). Select when color differentiation is required for circuit board assembly or identification purposes.

TE Connectivity 796644-4: Operates at 5.00mm pitch (0.197") versus the original 5.08mm specification. This represents a minor pitch tolerance variation. Extended thermal range to 110°C. RoHS3 compliant. Highest inventory availability (29,492 units). Select only when PCB layout accommodates the 5.00mm pitch tolerance or when pitch flexibility is engineered into the design.

All three substitutes are manufactured by TE Connectivity AMP Connectors, a qualified supplier with established reliability in terminal block production. Contact material differences (brass vs. copper alloy) and finish variations (gold vs. tin) do not compromise electrical performance within the specified 15 A / 300 V operating envelope.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796644-4 be used as a direct replacement despite the 5.00mm pitch specification?

A: The 796644-4 operates at 0.197" (5.00mm) pitch versus the original 0.200" (5.08mm). This 0.08mm difference is within industry tolerance for terminal block spacing but requires PCB layout verification. Direct substitution is only valid if the receiving PCB footprint accommodates 5.00mm pitch or if design margins permit the tolerance variation. Consult PCB documentation before selection.

Q: What is the difference between gold and tin contact finishes?

A: The Molex 0395326504 features gold-plated contacts; the TE substitutes use tin plating. Both finishes provide adequate corrosion resistance and electrical conductivity for the 15 A / 300 V rating. Gold offers superior oxidation resistance in high-humidity or corrosive environments; tin is standard for general industrial applications. Select based on environmental exposure requirements.

Q: Are all substitutes RoHS3 compliant?

A: TE 796638-4 and 796644-4 are explicitly RoHS3 compliant. TE 796639-4 is listed as RoHS compliant with vendor-undefined REACH status. For applications requiring strict RoHS3 certification, 796638-4 or 796644-4 are preferred.

Q: What is the inventory status of each part?

A: Molex 0395326504: 1,052 units. TE 796638-4: 3,793 units. TE 796639-4: 3,458 units. TE 796644-4: 29,492 units. The TE 796644-4 offers the highest availability, though pitch specification must be verified for compatibility.

Q: Can housing color be used as a selection criterion?

A: Yes. The Molex original and TE 796638-4 and 796644-4 are green; TE 796639-4 is black. Color serves as a visual identifier during assembly and troubleshooting but does not affect electrical or mechanical function. Select based on assembly documentation or color-coding standards.

Q: What is the contact tail length difference between the original and substitutes?

A: Molex 0395326504: 0.150" (3.81mm). TE substitutes: 0.138" (4.60mm). This 0.012" (0.31mm) difference is minor and does not affect solder joint quality or mechanical retention on standard PCB through-hole pads. Both dimensions are within acceptable soldering specifications.
