Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH04210 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (15 A UL), voltage rating (300 V UL), and contact material composition must support identical load conditions
• Physical Configuration: 4-position count, 0.200" (5.08mm) pitch, 90° right-angle orientation, and shrouded male pin design ensure mechanical and electrical compatibility
• Termination & Mounting: Solder termination and through-hole mounting type must match to maintain PCB assembly compatibility
• Environmental & Compliance: Operating temperature range, flammability rating (UL94 V-0), and RoHS compliance status determine suitability for equivalent applications
• Contact & Housing Materials: Brass contacts with tin mating finish and PBT or equivalent housing materials ensure reliable long-term performance

The substitute part 796639-4 (TE Connectivity AMP Connectors) meets these criteria with functionally equivalent electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH04210 and 796639-4 are active production components with equivalent electrical ratings and mechanical configurations. Selection between these parts should be based on:

• Supply Availability: The ELFH04210 has 1104 units in stock; the 796639-4 has 3458 units available, providing flexibility for high-volume procurement
• Compliance Status: Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards, suitable for regulated applications
• Operating Temperature: The 796639-4 supports an extended upper temperature limit of 110°C versus 105°C for the ELFH04210, providing additional thermal margin in demanding environments
• Housing Material Differences: PBT (ELFH04210) and PA66 Nylon 6/6 (796639-4) offer equivalent performance under specified electrical and thermal conditions; material selection may depend on specific chemical resistance or mechanical property requirements
• Contact Material: Brass (ELFH04210) and copper alloy (796639-4) both deliver equivalent electrical performance at rated current and voltage; contact material selection does not affect functional compatibility

Frequently Asked Questions (FAQ)

Q: Can 796639-4 be used as a direct replacement for ELFH04210 in existing designs?

A: Yes. Both parts share identical electrical ratings (15 A, 300 V), pitch (0.200"/5.08mm), position count (4), orientation (90° right angle), and termination method (solder through-hole). Physical dimensions are compatible with minor insulation height variance (0.319" vs. 0.329"). No design modification is required.

Q: What are the material differences between these parts?

A: The ELFH04210 uses PBT housing with brass contacts; the 796639-4 uses PA66 Nylon 6/6 housing with copper alloy contacts. Both materials meet UL94 V-0 flammability standards and support identical electrical performance. Material selection depends on application-specific requirements for chemical resistance or mechanical properties.

Q: Are there temperature rating differences?

A: The ELFH04210 operates from -40°C to 105°C; the 796639-4 operates from -40°C to 110°C. The TE Connectivity part provides a 5°C higher upper temperature limit, offering additional thermal margin in high-temperature applications.

Q: Do both parts meet RoHS compliance?

A: Yes. The ELFH04210 is ROHS3 Compliant; the 796639-4 is RoHS Compliant. Both parts satisfy RoHS requirements for regulated applications.

Q: What is the pitch specification, and why does it matter?

A: Both parts have a 0.200" (5.08mm) pitch, which defines the center-to-center spacing between adjacent pins. This specification is critical for PCB footprint compatibility and mating connector alignment. Pitch equivalence ensures direct mechanical and electrical interchangeability.

Q: Can these parts be used in high-current applications?

A: Both parts are rated for 15 A (UL) at 300 V (UL). Current capacity is determined by contact material, wire gauge compatibility, and thermal dissipation. Verify that PCB trace width, solder joint design, and wire gauge meet application current requirements.

Q: What does "shrouded (4 side)" mean?

A: Shrouding on all four sides provides mechanical protection and prevents accidental contact with live pins during assembly and operation. This design feature is identical on both the ELFH04210 and 796639-4.
