Key Parameters

Substitute Part Grouping Explanation

The ELFH04120 has one identified equivalent substitute: TE Connectivity AMP Connectors part number 282812-4. This substitution is valid based on the following critical parameters that remain consistent between both parts:

• Number of Positions: 4
• Pitch: 0.197" (5.00mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (2 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Current - UL: 15 A
• Voltage - UL: 300 V
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

These parameters define the functional and electrical compatibility envelope for direct substitution in applications designed for the ELFH04120.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH04120 and 282812-4 maintain active product status and meet UL94 V-0 flammability requirements. The 282812-4 offers an extended operating temperature range of -40°C to 110°C compared to the ELFH04120's -40°C to 105°C, providing additional thermal margin for applications operating near the upper temperature limit. Both parts are RoHS compliant, with the 282812-4 meeting ROHS3 specifications.

The primary differences between these parts are material composition (brass vs. copper alloy contacts; PBT vs. PA66 housing), contact tail length (0.155" vs. 0.138"), and insulation height (0.319" vs. 0.329"). These variations do not affect electrical performance or functional compatibility when the parts are used within their specified electrical and thermal parameters.

Selection between these parts should be based on PCB layout requirements, packaging availability, and material compatibility with the specific application environment.

Frequently Asked Questions (FAQ)

Q: Can the 282812-4 be used as a direct replacement for the ELFH04120 in existing designs?

A: Yes, the 282812-4 is electrically and functionally equivalent to the ELFH04120. Both parts share identical pitch, position count, orientation, current rating, voltage rating, and flammability classification. PCB layout verification is recommended to confirm compatibility with the slight differences in contact tail length and insulation height.

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

A: The primary differences are contact material (brass vs. copper alloy), housing material (PBT vs. PA66), contact tail length (0.155" vs. 0.138"), and operating temperature range (-40°C to 105°C vs. -40°C to 110°C). These differences do not affect electrical performance within the specified ratings.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH04120 is RoHS Compliant, and the 282812-4 is ROHS3 Compliant. Both meet RoHS requirements for lead-free construction.

Q: What is the difference in packaging between these parts?

A: The ELFH04120 is supplied in Tray packaging, while the 282812-4 is supplied in Bulk packaging. Packaging selection may affect handling, storage, and ordering quantities.

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

A: The 282812-4 supports operation up to 110°C, providing a 5°C margin above the ELFH04120's 105°C maximum. For applications operating near or above 105°C, the 282812-4 is the appropriate selection.
