ELFH11210E Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH11210E is an 11-position terminal block header manufactured by Amphenol PCD. This component features male pins with 4-side shrouding, 0.200" (5.08mm) pitch spacing, and right-angle through-hole mounting. The part is actively produced and stocked with 1,098 units available. Terminal block headers of this configuration are essential in applications requiring reliable electrical connections with mechanical strain relief and organized wire management in industrial control systems, power distribution, and signal routing applications.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH11210E is determined by the following critical parameters:

Position Count & Pitch: Must be 11 positions at 0.200" (5.08mm) spacing
Connector Type & Orientation: Must be male pin header with 4-side shrouding and 90° right-angle configuration
Mounting & Termination: Must support through-hole solder termination
Electrical Ratings: Must meet or exceed UL voltage (300 V) and current (15 A) specifications
Environmental Compliance: Must be RoHS compliant with operating temperature range suitable for the application
Physical Compatibility: Contact tail length, insulation height, and housing material must accommodate PCB layout and mating connector specifications

The substitute part 1780500000 (Weidmüller Omnimate SL series) meets these core substitution criteria while maintaining functional equivalence in standard applications.

Engineering Selection Recommendations

Both the ELFH11210E and 1780500000 are active production components with RoHS compliance and UL94 V-0 flammability ratings. The Weidmüller 1780500000 provides higher current capacity (18.5 A vs. 15 A) under UL specifications, making it suitable for applications requiring additional current margin. The Amphenol ELFH11210E maintains a wider operating temperature range on the high end (105°C vs. 100°C). Physical dimensions differ slightly in contact tail length and insulation height; PCB layout compatibility must be verified before substitution. Both parts are suitable for industrial control, power distribution, and signal routing applications where 11-position 5.08mm pitch terminal block headers are specified.

Frequently Asked Questions (FAQ)

Q: Can the 1780500000 directly replace the ELFH11210E in existing designs?

A: Direct substitution is possible for applications where the physical dimensions (contact tail length: 0.126" vs. 0.155", insulation height: 0.335" vs. 0.319") do not conflict with PCB layout constraints. Verify mating connector compatibility and PCB hole spacing before implementation.

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

A: Both parts share identical position count (11), pitch (5.08mm), orientation (90° right angle), and voltage rating (300 V UL). The Weidmüller part offers higher current capacity (18.5 A vs. 15 A) and lower maximum operating temperature (100°C vs. 105°C). Contact tail and insulation heights differ by approximately 0.03" and 0.016" respectively.

Q: Are both parts RoHS compliant?

A: Yes, both ELFH11210E and 1780500000 are RoHS compliant with UL94 V-0 flammability ratings and unlimited moisture sensitivity level (MSL 1).

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. Choose ELFH11210E for designs requiring maximum operating temperature of 105°C. Choose 1780500000 for applications benefiting from higher current capacity (18.5 A) or extended low-temperature operation (-50°C). Verify physical compatibility with PCB layout in both cases.

Q: What is the significance of the 4-side shrouding feature?

A: 4-side shrouding provides mechanical strain relief and organized wire management by containing wires within the header structure, reducing risk of accidental contact and improving assembly reliability in industrial environments.
