TE Connectivity 1-1546110-2 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1546110-2 is a 12-position terminal block header with male pins, shrouded on 2 sides, featuring 0.200" (5.08mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The Buchanan series part maintains electrical specifications suitable for 15 A UL current and 300 V UL voltage applications across an operating temperature range of -40°C to 110°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1546110-2 is determined by strict equivalence across the following critical parameters: 12-position configuration, 0.200" (5.08mm) pitch, 90° right-angle orientation, solder termination, through-hole mounting, 15 A UL current rating, 300 V UL voltage rating, and UL94 V-0 flammability compliance.

The Amphenol PCD ELFH series terminal block headers meet these core electrical and mechanical requirements. Two distinct shrouding configurations are available within the substitute group:

Direct Equivalent (2-Side Shrouded): ELFH12220 provides identical shrouding geometry to the main part, with 2-side shroud design.

Functional Equivalents (4-Side Shrouded): ELFH12210 and ELFH12230 feature enhanced 4-side shrouding, providing additional mechanical protection while maintaining all critical electrical parameters and pitch specifications.

All substitute parts maintain UL94 V-0 flammability rating, tin contact mating finish, and through-hole solder termination. Operating temperature ranges for ELFH series parts extend to 105°C maximum, which is within the operational envelope of the original part's -40°C to 110°C specification.

Parameter Comparison

Engineering Selection Recommendations

ELFH12220 Selection: This part provides direct mechanical and electrical equivalence to the 1-1546110-2, with identical 2-side shrouding configuration. ELFH12220 is actively manufactured by Amphenol PCD and carries RoHS compliance certification. This part is the primary recommendation for direct replacement in applications requiring identical form factor and shrouding geometry.

ELFH12210 and ELFH12230 Selection: Both parts offer enhanced 4-side shrouding while maintaining all critical electrical parameters and pitch specifications. ELFH12210 is supplied in bulk packaging with ROHS3 compliance. ELFH12230 is supplied in tray packaging with RoHS compliance. These parts are suitable for applications where increased mechanical protection and shrouding coverage provide design advantages, provided PCB layout and connector mating geometry accommodate the 4-side shroud profile.

All three substitute parts are actively produced and carry current compliance certifications, eliminating obsolescence risk associated with the original TE Connectivity part. Selection between 2-side and 4-side shrouding variants depends on specific application requirements for mechanical protection and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can ELFH12220 be used as a direct replacement for 1-1546110-2?

A: Yes. ELFH12220 maintains identical electrical specifications (15 A UL, 300 V UL), pitch (0.200"/5.08mm), position count (12), orientation (90° right angle), termination method (solder), and mounting type (through hole). Both parts feature 2-side shrouding and UL94 V-0 flammability rating. The primary difference is housing material composition and active product status.

Q: What is the difference between ELFH12220 and ELFH12210/ELFH12230?

A: ELFH12220 features 2-side shrouding identical to the original part. ELFH12210 and ELFH12230 feature 4-side shrouding, providing additional mechanical protection on all sides. All three parts share identical electrical ratings, pitch, position count, and orientation. The 4-side shrouding variants require verification of PCB layout compatibility to ensure adequate clearance around the connector perimeter.

Q: Are there compliance differences between the substitute parts?

A: ELFH12220 and ELFH12230 carry RoHS compliance certification. ELFH12210 carries ROHS3 compliance certification. All three parts meet UL94 V-0 flammability requirements. The original 1-1546110-2 lists RoHS status as not applicable. For applications requiring specific RoHS compliance levels, ELFH12210 (ROHS3) or ELFH12220/ELFH12230 (RoHS) should be selected accordingly.

Q: What is the operating temperature difference between the original part and substitutes?

A: The original 1-1546110-2 operates from -40°C to 110°C. All three substitute parts (ELFH12220, ELFH12210, ELFH12230) operate from -40°C to 105°C. The 5°C reduction in maximum operating temperature does not affect most industrial applications and remains within standard thermal operating ranges for terminal block connectors.

Q: Are packaging differences significant for component selection?

A: ELFH12220 is supplied in tray packaging. ELFH12210 is supplied in bulk packaging. ELFH12230 is supplied in tray packaging. Packaging selection depends on production volume requirements and inventory management procedures. Electrical and mechanical specifications are identical regardless of packaging format.

Q: Can ELFH12210 or ELFH12230 be used in applications designed for 2-side shrouding?

A: ELFH12210 and ELFH12230 feature 4-side shrouding, which extends beyond the footprint of 2-side shrouded connectors. PCB layout and mating connector geometry must be verified to ensure the expanded shroud profile does not create mechanical interference. If space constraints exist, ELFH12220 (2-side shrouding) is the appropriate selection.
