ELFH07450 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH07450 is a 7-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with male pins and 4-side shrouding. This component operates at 300V UL and 15A UL current rating with a 0.300" (7.62mm) pitch configuration. The part is actively produced and RoHS compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELFH07450 is determined by electrical and mechanical compatibility across the following critical parameters:

• Position Count & Pitch: Both main and substitute parts maintain 7 positions at 0.300" (7.62mm) pitch, ensuring PCB footprint compatibility
• Mounting Configuration: Vertical through-hole solder termination is consistent across all parts
• Electrical Ratings: UL voltage (300V) and current (15A) ratings are matched or exceeded
• Shrouding Type: The ELFH07450 features 4-side shrouding; the substitute part (1625080000) features 2-side shrouding, representing a functional variation in mechanical protection
• Compliance: All parts maintain UL94 V-0 flammability rating and RoHS compliance

The substitute part 1625080000 (Weidmüller Omnimate SL series) meets the core electrical and positional requirements for direct substitution in applications where the reduced shrouding profile is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH07450 and 1625080000 are active production components with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts is based on application-specific requirements:

ELFH07450 (Amphenol PCD) is suitable for applications requiring maximum mechanical protection through 4-side shrouding and operation up to 105°C.

1625080000 (Weidmüller Omnimate SL) provides equivalent electrical performance with 2-side shrouding, extended IEC electrical ratings (800V, 18.5A), and operation within -50°C to 100°C range. This part is appropriate for applications where the reduced shrouding profile is compatible with board layout and environmental protection requirements.

Both parts are certified for the same UL voltage and current specifications (300V, 15A) and maintain identical moisture sensitivity and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can 1625080000 directly replace ELFH07450 on existing PCBs?

A: Yes, both parts share identical pitch (0.300"/7.62mm), position count (7), and through-hole solder termination. PCB footprints are compatible. The primary difference is shrouding configuration: ELFH07450 provides 4-side shrouding while 1625080000 provides 2-side shrouding. Verify that the reduced shrouding does not conflict with board layout or environmental protection requirements.

Q: What are the electrical compatibility limits?

A: Both parts meet UL specifications of 300V and 15A. The 1625080000 additionally supports IEC ratings of 800V and 18.5A. Selection should be based on circuit requirements and applicable safety standards (UL or IEC).

Q: Are there temperature operating range differences?

A: ELFH07450 operates to 105°C maximum. 1625080000 operates within -50°C to 100°C. For applications exceeding 100°C, ELFH07450 is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference in contact material?

A: ELFH07450 uses brass contacts; 1625080000 uses copper alloy contacts. Both are tin-plated for mating surface finish. Contact material selection does not affect electrical performance within the specified ratings.
