ELFH04450 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH04450 is a 4-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.300" (7.62mm) pitch spacing. This shrouded male pin header operates at 15 A (UL) and 300 V (UL), with solder termination and tin-plated brass contacts. The component is actively produced and RoHS compliant, serving applications requiring reliable electrical interconnection in industrial and commercial equipment. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH04450 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 4 positions at 0.300" (7.62mm) spacing (mechanical compatibility with mating connectors)
• Header Configuration: Male pins with 4-side shrouding (electrical safety and mechanical fit)
• Mounting Method: Through-hole solder termination (PCB assembly compatibility)
• Electrical Performance: Minimum 15 A (UL) current and 300 V (UL) voltage ratings (functional equivalence)
• Compliance: RoHS compliance and UL94 V-0 flammability rating (regulatory and safety requirements)
• Product Status: Active manufacturing status (supply chain reliability)

The substitute part 1625270000 (Weidmüller Omnimate SL series) meets all critical substitution criteria. This part maintains identical mechanical and electrical specifications for the core application requirements while offering alternative sourcing from a qualified manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH04450 and 1625270000 are active production components with full RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts is based on supply availability and design specifications.

The ELFH04450 supports continuous operation at 105°C, making it suitable for higher-temperature environments. The 1625270000 operates within −50°C to 100°C, appropriate for standard industrial temperature ranges. The Weidmüller part provides additional IEC electrical ratings (18.5 A at 800 V), offering margin above UL specifications in applications requiring IEC compliance documentation.

Both components feature identical mechanical interfaces (4-position, 0.300" pitch, vertical through-hole, shrouded male pins) and meet minimum UL electrical requirements (15 A, 300 V). Contact material differs (brass versus copper alloy), with both materials providing adequate conductivity and tin plating for solder compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1625270000 directly replace the ELFH04450 in existing designs?

A: Yes. Both parts share identical mechanical dimensions (4 positions, 0.300" pitch, vertical orientation, through-hole solder termination) and meet or exceed the same UL electrical ratings (15 A, 300 V). Mating connectors and PCB footprints are compatible.

Q: What are the temperature operating differences?

A: The ELFH04450 operates continuously at 105°C, while the 1625270000 operates within −50°C to 100°C. For applications requiring sustained operation above 100°C, the ELFH04450 is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELFH04450 and 1625270000 are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial equipment.

Q: What is the difference in contact material?

A: The ELFH04450 uses brass contacts, while the 1625270000 uses copper alloy contacts. Both materials are tin-plated and provide equivalent electrical performance for solder termination applications.

Q: Do both parts support the same current and voltage ratings?

A: Both parts meet UL ratings of 15 A and 300 V. The 1625270000 additionally provides IEC ratings of 18.5 A and 800 V, offering higher margins for applications requiring IEC compliance documentation.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. Current inventory availability should be verified with the respective manufacturers or authorized distributors.
