Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-796866-1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 21
• Pitch: 0.200" (5.08mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Voltage - UL: 300 V
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current - UL: Substitute must meet or exceed 15 A
• Operating Temperature: Substitute must support minimum -40°C to 105°C range
• Contact Material: Copper Alloy or Brass acceptable
• Housing Material: Polyamide (PA66), Nylon 6/6 or Polybutylene Terephthalate (PBT) acceptable
• Product Status: Active status preferred for ongoing availability

The identified substitutes meet all mandatory parameters and maintain electrical and mechanical compatibility with the original component.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395360021 is suitable for applications where the original TE Connectivity 2-796866-1 is no longer available. This substitute provides 18 A current capacity, exceeding the original 15 A specification, and maintains full electrical compatibility at 300 V. The component is active in production and carries ROHS3 compliance certification. Operating temperature range extends to -40°C to 105°C, which covers the lower bound of the original specification. Housing material composition (Polyamide PA66/Nylon 6/6) and flammability rating (UL94 V-0) are identical to the original.

Amphenol PCD ELFH21210E provides an alternative with identical current and voltage ratings to the original component. This substitute is active in production and carries RoHS compliance certification. The housing material differs, utilizing Polybutylene Terephthalate (PBT) instead of Polyamide, which maintains UL94 V-0 flammability rating. Operating temperature range is -40°C to 105°C. Contact tail length and insulation height specifications differ from the original but remain within acceptable mechanical envelope parameters for standard through-hole PCB mounting applications.

Both substitutes maintain the critical electrical parameters (21 positions, 5.08mm pitch, 90° right-angle orientation, 300 V rating, UL94 V-0 flammability) required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395360021 directly replace the TE Connectivity 2-796866-1 in existing designs?

A: Yes. Both components share identical pitch (5.08mm), position count (21), orientation (90° right angle), termination style (solder), and voltage rating (300 V). The Molex substitute provides 18 A capacity, which exceeds the original 15 A specification. PCB footprints are compatible for through-hole mounting applications.

Q: What is the difference between the Molex and Amphenol substitutes?

A: The primary differences are housing material composition and contact material. Molex 0395360021 uses Polyamide (PA66) housing with Brass contacts, while Amphenol PCD ELFH21210E uses Polybutylene Terephthalate (PBT) housing with Brass contacts. Both maintain UL94 V-0 flammability rating and 300 V electrical rating. Contact tail length and insulation height specifications differ between the two substitutes.

Q: Are there temperature limitations when substituting these parts?

A: The original TE Connectivity component operates from -40°C to 110°C. Both substitutes operate from -40°C to 105°C. For applications requiring operation above 105°C, the original specification cannot be met by these substitutes.

Q: Do the substitute parts carry the same compliance certifications?

A: Both substitutes carry RoHS compliance. Molex 0395360021 is ROHS3 compliant, matching the original. Amphenol PCD ELFH21210E carries RoHS compliance. All three components maintain UL94 V-0 flammability rating and are rated for 300 V operation.

Q: What is the current capacity difference between the original and substitutes?

A: The TE Connectivity 2-796866-1 is rated at 15 A (UL). Molex 0395360021 is rated at 18 A (UL), providing additional capacity margin. Amphenol PCD ELFH21210E matches the original at 15 A (UL).

Q: Are these components available in different packaging formats?

A: The TE Connectivity original is supplied in standard packaging. Molex 0395360021 is supplied in bulk packaging. Amphenol PCD ELFH21210E is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
