Key Parameters

Substitute Part Grouping Explanation

The DF3EA-3P-2H(24) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Series Match: Both parts belong to the DF3 series
• Connector Type & Contact Configuration: Both are shrouded 4-wall headers with male pins
• Position Count & Pitch: Identical 3-position configuration with 0.079" (2.00mm) mating pitch
• Mounting & Termination: Both are surface mount, right-angle with solder termination
• Electrical Ratings: Both rated for 250VAC operation
• Temperature Range: Identical -55°C ~ 105°C operating range
• Material Compliance: Both meet UL94 V-0 flammability requirements
• Insulation Material: Both use Polyamide (PA), Nylon
• Contact Material & Finish: Both feature brass contacts with tin finish

The primary difference is product status: DF3EA-3P-2H(20) is obsolete, while DF3EA-3P-2H(24) is Last Time Buy with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-3P-2H(24) is the appropriate substitute for the obsolete DF3EA-3P-2H(20). Both parts maintain identical electrical and mechanical specifications across all critical parameters: connector type, position count, pitch, mounting configuration, voltage rating, temperature range, and material compliance.

The DF3EA-3P-2H(24) offers additional advantages: it carries Last Time Buy status with higher inventory availability (1168 pcs vs. 871 pcs), includes explicit RoHS compliance certification, and is packaged in tubes for improved handling. The only cosmetic difference is insulation color (black vs. beige), which does not affect functional performance or compatibility.

For new designs or ongoing production requiring this connector family, the DF3EA-3P-2H(24) should be selected to ensure long-term supply continuity and compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-3P-2H(24) be used as a direct replacement for DF3EA-3P-2H(20)?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters. They share the same series designation, connector type, position count, pitch, mounting method, voltage rating, temperature range, and material specifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and packaging. DF3EA-3P-2H(20) is obsolete, while DF3EA-3P-2H(24) is Last Time Buy with higher inventory. DF3EA-3P-2H(24) includes RoHS compliance documentation and tube packaging. Insulation color differs (beige vs. black) but does not affect electrical or mechanical function.

Q: Are there any compatibility concerns with PCB layouts or mating connectors?

A: No. Both parts maintain identical pitch (2.00mm), position count (3), mounting type (surface mount, right angle), and shrouding configuration (4-wall). Existing PCB designs and mating connector specifications require no modification.

Q: What is the significance of the Last Time Buy status for DF3EA-3P-2H(24)?

A: Last Time Buy indicates this is the final production run before the part is discontinued. Procurement should plan accordingly for long-term inventory needs, as future availability will be limited to existing stock.

Q: Does the RoHS compliance of DF3EA-3P-2H(24) affect compatibility?

A: No. RoHS compliance is an environmental and regulatory attribute that does not alter electrical or mechanical performance. It indicates the substitute part meets hazardous substance restrictions and is suitable for regulated markets.
