Substitute Part Grouping Explanation

Substitution eligibility for the ELFT12150 is determined by strict alignment of the following critical parameters:

12-position configuration with single level
0.197" (5.00mm) pitch spacing
90° free-hanging in-line mounting orientation
Screw-rising cage clamp termination mechanism
Female socket connector type
15 A UL current rating and 300 V UL voltage rating
UL94 V-0 flammability classification
Tin contact mating finish
RoHS compliance status

The substitute part 1-284046-2 (TE Connectivity AMP Connectors, Buchanan series) meets all critical substitution criteria. Variations in secondary parameters such as housing material composition, contact material type, wire gauge range, and operating temperature range do not preclude functional equivalence when the primary electrical and mechanical specifications align.

Engineering Selection Recommendations

Both the ELFT12150 and 1-284046-2 maintain active product status and meet all regulatory compliance requirements. The ELFT12150 carries RoHS compliance certification, while the 1-284046-2 carries ROHS3 compliance, both satisfying current environmental standards. Both components are classified as EAR99 for export control purposes and share identical HTSUS commodity codes.

Selection between these parts should be based on:

Packaging format requirements (ELFT12150 supplied in trays; 1-284046-2 supplied in bulk)
Current inventory availability (ELFT12150: 888 units; 1-284046-2: 909 units)
Wire gauge compatibility with your application (ELFT12150 supports 12 AWG and 14-26 AWG; 1-284046-2 supports 12-30 AWG)
Operating temperature range requirements (ELFT12150 rated to 105°C; 1-284046-2 rated -40°C to 110°C)
Housing material compatibility with environmental conditions (ELFT12150 uses PPO; 1-284046-2 uses PA66/Nylon 6/6)

Frequently Asked Questions (FAQ)

Q: Can 1-284046-2 be used as a direct replacement for ELFT12150?

A: Yes. Both parts share identical electrical ratings (15 A at 300 V), mechanical configuration (12 positions at 5.00mm pitch with 90° entry), termination method (screw-rising cage clamp), and flammability classification (UL94 V-0). Physical differences in housing material and color do not affect functional compatibility in applications where these parameters are not design-critical.

Q: What are the key differences between these parts?

A: Primary differences include housing material (PPO versus PA66/Nylon 6/6), contact material (Copper Alloy versus Phosphor Bronze), color (Black versus Green), wire gauge range (14-26 AWG versus 12-30 AWG), operating temperature range (105°C versus -40°C to 110°C), and insulation height (26.16mm versus 25.00mm). Wire strip length also varies slightly (7.87mm versus 6-7.5mm).

Q: Are there packaging differences?

A: Yes. The ELFT12150 is supplied in trays, while the 1-284046-2 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet RoHS requirements?

A: Yes. The ELFT12150 is RoHS Compliant, and the 1-284046-2 is ROHS3 Compliant. Both satisfy current environmental regulations.

Q: Which part should I select for high-temperature applications?

A: The 1-284046-2 offers a wider operating temperature range (-40°C to 110°C) compared to the ELFT12150 (105°C maximum). For applications requiring operation above 105°C, the 1-284046-2 is the appropriate selection.

Q: Are the wire gauge ranges compatible?

A: The ELFT12150 accommodates 12 AWG and 14-26 AWG wire gauges. The 1-284046-2 accommodates 12-30 AWG. The 1-284046-2 provides broader gauge compatibility. Verify your application's wire gauge requirements against the selected part's specifications.
