Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-796866-0 terminal block header is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain identical 20-position configuration with 0.200" (5.08mm) pitch spacing to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Orientation and Mounting: The substitute must feature 90° right-angle orientation with through-hole solder termination to match the original mounting methodology and board integration requirements.

Electrical Performance: The substitute must meet or exceed the voltage rating of 300 V UL and support the required current capacity for the application circuit.

Shrouding Configuration: The substitute must maintain four-side shrouding to preserve the mechanical protection and polarization features of the original design.

Compliance and Material Standards: The substitute must maintain UL94 V-0 flammability rating and ROHS3 compliance to satisfy regulatory and safety requirements.

The Molex 0395360020 terminal block header satisfies all critical substitution parameters while offering active product status and enhanced current capacity.

Engineering Selection Recommendations

Primary Substitute: The Molex 0395360020 terminal block header is the qualified substitute for the TE Connectivity 2-796866-0. This substitution is supported by:

Compliance Alignment: Both components maintain ROHS3 compliance and UL94 V-0 flammability rating, satisfying regulatory requirements for equivalent product selection.

Electrical Equivalence: The Molex substitute meets the 300 V UL voltage requirement and exceeds the current capacity specification with an 18 A UL rating compared to the original 15 A specification, providing enhanced performance margin.

Mechanical Compatibility: Identical pitch spacing (0.200"/5.08mm), position count (20), orientation (90° right angle), and shrouding configuration (4-side) ensure direct mechanical compatibility with existing mating connectors and PCB footprints.

Active Product Status: The Molex 0395360020 maintains active product status within the Eurostyle ESE 39536 series, ensuring long-term availability and supply chain continuity.

Material and Construction: Both components utilize identical housing material (Polyamide PA66/Nylon 6/6) and tin contact mating finish, maintaining consistent electrical and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395360020 directly replace the TE Connectivity 2-796866-0 in existing designs?

A: Yes. The Molex 0395360020 maintains identical pitch (0.200"/5.08mm), position count (20), orientation (90° right angle), and shrouding configuration (4-side). The component interfaces with existing mating connectors and PCB layouts without modification.

Q: What are the key differences between these two terminal block headers?

A: The primary differences are manufacturer identity, product status (obsolete versus active), current capacity (15 A versus 18 A UL), operating temperature range (-40°C to 110°C versus -40°C to 105°C), contact material (copper alloy versus brass), and housing color (green versus black). All critical electrical and mechanical parameters remain equivalent.

Q: Does the higher current rating of the Molex substitute affect compatibility?

A: No. The 18 A UL rating of the Molex 0395360020 exceeds the 15 A requirement of the original design, providing additional performance margin without introducing compatibility issues. The component operates within the same 300 V UL voltage specification.

Q: Are both components RoHS compliant?

A: Yes. Both the TE Connectivity 2-796866-0 and Molex 0395360020 maintain ROHS3 compliance status, satisfying environmental and regulatory requirements for equivalent product selection.

Q: What is the significance of the four-side shrouding feature?

A: The four-side shrouding provides mechanical protection for the male pins, prevents accidental contact, and maintains polarization alignment during mating operations. Both components preserve this feature, ensuring equivalent safety and functional performance.

Q: How does the operating temperature range difference impact substitution?

A: The TE Connectivity component operates from -40°C to 110°C, while the Molex substitute operates from -40°C to 105°C. For applications operating within the -40°C to 105°C range, the Molex substitute provides equivalent thermal performance. Applications requiring operation above 105°C require evaluation against specific thermal requirements.

Q: What packaging considerations apply to the Molex substitute?

A: The Molex 0395360020 is supplied in bulk packaging, compared to the original component packaging designation. Verify bulk packaging compatibility with receiving, storage, and handling procedures for your production environment.

Q: Are the contact materials interchangeable?

A: Both components feature tin contact mating finish. The TE Connectivity component uses copper alloy contacts, while the Molex substitute uses brass contacts. Both materials provide equivalent electrical conductivity and corrosion resistance for this application category.
