Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395364021 is determined by strict alignment of the following parameters:

• Position Count & Pitch: All substitutes must maintain 21 positions at 0.200" (5.08mm) pitch
• Connector Type & Orientation: Header configuration with male pins, four-side shrouding, and 90° right-angle mounting
• Termination & Mounting: Solder termination with through-hole PCB mounting
• Electrical Ratings: Minimum 300 V UL voltage rating
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance
• Operating Range: -40°C to 105°C temperature specification

The identified substitutes—Molex 0395360021 and Amphenol PCD ELFH21210E—satisfy all mandatory parameters. Variations in current rating (15 A vs. 18 A), housing material composition, and contact tail length do not preclude substitution when electrical load requirements remain within the lower-rated component's specification.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395360021 is the manufacturer-recommended direct substitute. As an active Molex product within the same Eurostyle ESE 39536 series, it maintains identical mechanical and electrical specifications with the exception of housing material (Polyamide PA66 versus PA46) and a higher current rating (18 A versus 15 A). This part is suitable for applications where the original 0395364021 is no longer procurable.

Amphenol PCD ELFH21210E serves as a cross-manufacturer equivalent. While manufactured by a different supplier and utilizing polybutylene terephthalate (PBT) housing material, it maintains all critical electrical and mechanical parameters. This option provides supply chain diversification and is appropriate when Molex inventory is constrained. The ELFH series shares identical pitch, position count, orientation, and voltage rating.

Both substitutes carry active product status and current RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395360021 be used as a direct replacement for the 0395364021?

A: Yes. Both components share identical position count (21), pitch (5.08mm), orientation (90° right angle), termination method (solder), and voltage rating (300 V UL). The housing material differs (PA66 versus PA46), but this does not affect electrical or mechanical compatibility. The 0395360021 carries a higher current rating (18 A), making it suitable for applications within the original part's 15 A specification.

Q: What is the primary difference between the Molex 0395360021 and Amphenol PCD ELFH21210E?

A: Both parts are electrically and mechanically equivalent. The primary differences are manufacturer (Molex versus Amphenol PCD), housing material (Polyamide PA66 versus Polybutylene Terephthalate PBT), and minor dimensional variations in contact tail length and insulation height. These differences do not affect PCB mounting, solder termination, or electrical performance within the specified operating range.

Q: Are there packaging differences between these substitutes?

A: The Molex 0395360021 is supplied in bulk packaging, while the original 0395364021 packaging specification is not detailed. The Amphenol PCD ELFH21210E is also supplied in bulk. Packaging format does not affect component functionality or compatibility.

Q: Which substitute should be selected for new production designs?

A: Selection between the Molex 0395360021 and Amphenol PCD ELFH21210E depends on supply chain strategy and inventory availability. The Molex 0395360021 maintains manufacturer continuity within the Eurostyle ESE 39536 series. The Amphenol PCD ELFH21210E provides cross-manufacturer redundancy. Both are active products with current RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Q: Are these parts suitable for high-temperature applications?

A: Both substitutes operate across the -40°C to 105°C temperature range, identical to the original part. Applications requiring operation beyond this range require alternative component selection.

Q: Do these substitutes maintain the same solder termination compatibility?

A: Yes. All three parts utilize solder termination with through-hole mounting. PCB layout and soldering processes remain unchanged when substituting between these components.
