ELFP03110 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The ELFP03110 is a 3-position terminal block plug manufactured by Amphenol PCD, designed for 0.197" (5.00mm) pitch applications with 180° free-hanging in-line mounting. This component features female sockets with screw-rising cage clamp termination, rated for 15 A at 300 V (UL). The part is currently active in production with 745 units in stock.

Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional characteristics align within acceptable tolerances for the terminal block category. Substitution becomes necessary due to inventory availability, lead time considerations, or design flexibility requirements across compatible connector families.

Key Parameters

Substitute Part Grouping Explanation

Substitute part 1755745 (Phoenix Contact COMBICON PT series) is identified based on the following alignment criteria:

Matching Parameters:

• Number of positions: 3
• Pitch: 0.197" (5.00mm)
• Termination style: Screw - Rising Cage Clamp
• Mounting type: Free Hanging (In-Line)
• Voltage rating (UL): 300 V
• Material flammability rating: UL94 V-0
• Contact mating finish: Tin
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99

Differing Parameters:

• Plug wire entry: 90° (versus 180° for ELFP03110)
• Current rating (UL): 10 A (versus 15 A for ELFP03110)
• Wire gauge range: 14-28 AWG (versus 12 AWG, 14-26 AWG for ELFP03110)
• Torque specification: 0.35-0.4 Nm (versus 0.79 Nm for ELFP03110)
• Housing material: Polyamide (PA), Nylon (versus Polyphenylene Oxide for ELFP03110)

The 1755745 operates at a lower current capacity and features a 90° wire entry orientation, requiring evaluation of application-specific requirements before substitution.

Parameter Comparison

Engineering Selection Recommendations

ELFP03110 (Primary Selection):

• Supports higher current capacity at 15 A, suitable for applications requiring maximum current handling
• 180° wire entry orientation accommodates in-line configurations with straight wire approach
• Wire gauge support extends to 12 AWG for heavier gauge applications
• Higher screw torque specification (0.79 Nm) provides robust mechanical retention
• RoHS Compliant status meets standard environmental requirements
• Active product status with 745 units in stock ensures availability

1755745 (Substitute Selection):

• Suitable for applications with current requirements at or below 10 A
• 90° wire entry orientation requires perpendicular wire approach, affecting board layout
• Wire gauge range 14-28 AWG accommodates finer gauge applications
• Lower screw torque specification (0.35-0.4 Nm) requires adjusted assembly procedures
• ROHS3 Compliant status meets enhanced environmental requirements
• Active product status with 1038 units in stock provides alternative availability
• Polyamide housing material differs from PPO, affecting thermal and mechanical properties

Selection between these parts depends on application current requirements, physical space constraints, wire gauge specifications, and assembly torque capabilities.

Frequently Asked Questions (FAQ)

Q: Can 1755745 directly replace ELFP03110 in existing designs?

A: Direct replacement is not recommended without design review. The 1755745 features 90° wire entry versus the ELFP03110's 180° orientation, requiring different board layout and wire routing. Current rating difference (10 A versus 15 A) must be verified against application requirements.

Q: What is the impact of the different wire entry angles?

A: The 180° entry on ELFP03110 accommodates straight in-line wire approach, while the 90° entry on 1755745 requires perpendicular wire routing. This affects PCB layout, connector positioning, and cable management strategies.

Q: Are the screw torque specifications interchangeable?

A: No. ELFP03110 requires 0.79 Nm torque, while 1755745 requires 0.35-0.4 Nm. Assembly procedures and torque tools must be adjusted accordingly to prevent under-tightening or over-tightening.

Q: Do both parts support the same wire gauges?

A: No. ELFP03110 supports 12 AWG and 14-26 AWG, while 1755745 supports 14-28 AWG. Applications using 12 AWG wire require ELFP03110.

Q: What are the housing material differences?

A: ELFP03110 uses Polyphenylene Oxide (PPO), while 1755745 uses Polyamide (PA) and Nylon. PPO offers different thermal and mechanical characteristics compared to polyamide materials.

Q: Are both parts RoHS compliant?

A: Yes. ELFP03110 is RoHS Compliant, and 1755745 is ROHS3 Compliant. Both meet environmental compliance requirements.

Q: What is the current rating difference impact?

A: ELFP03110 is rated for 15 A at 300 V (UL), while 1755745 is rated for 10 A at 300 V (UL). Applications exceeding 10 A require ELFP03110.
