ED1110/3 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The ED1110/3 is a 3-position terminal block plug manufactured by On Shore Technology Inc., designed for screw-terminated connections with female sockets at 0.197" (5.00mm) pitch. This component operates at 300V UL with a 15A current rating and supports wire gauges from 10-22 AWG. The part is actively produced and maintains full RoHS3 and REACH compliance, making it suitable for industrial and commercial applications requiring reliable screw-terminal connectivity.

Equivalent and substitute parts are identified when design requirements permit flexibility in wire gauge ranges, contact materials, or specific mechanical features while maintaining core electrical performance and safety certifications.

Substitute Part Grouping Explanation

The OSTTS03715B qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

3-position configuration with 0.197" (5.00mm) pitch
Female socket plug type with screw termination
Free hanging (in-line) mounting orientation
300V UL voltage rating
-30°C ~ 105°C operating temperature range
UL94 V-0 flammability rating
RoHS3 and REACH compliance

Allowable Variations:

Wire gauge range: OSTTS03715B supports 12-24 AWG (0.34-2.5mm²), which encompasses the upper portion of ED1110/3's 10-22 AWG range. Applications using wire gauges 12-22 AWG are fully compatible.
Contact material: OSTTS03715B uses brass contacts versus ED1110/3's copper tin alloy. Both materials meet UL94 V-0 requirements and maintain electrical performance within specified voltage and current parameters.
Housing material: OSTTS03715B uses brass housing versus ED1110/3's polyamide (PA) nylon. Both materials satisfy flammability and environmental compliance requirements.
Screw torque: OSTTS03715B specifies 0.4 Nm (4.6 Lb-In) versus ED1110/3's 0.5 Nm (4.4 Lb-In). Both values fall within acceptable fastening ranges for this connector class.

Engineering Selection Recommendations

Both ED1110/3 and OSTTS03715B are active products with identical compliance certifications (RoHS3, REACH Unaffected, UL94 V-0). Selection between these parts should be based on application-specific wire gauge requirements:

ED1110/3 is specified for applications requiring support of 10 AWG wire (larger diameter conductors up to 2.5mm²).
OSTTS03715B is suitable for applications using wire gauges 12-24 AWG (0.34-2.5mm²).

For applications using wire gauges within the 12-22 AWG range, both parts deliver equivalent electrical performance and safety characteristics. Material differences (copper tin alloy vs. brass contacts; polyamide vs. brass housing) do not affect functional compatibility within the specified voltage (300V) and current parameters.

Frequently Asked Questions (FAQ)

Q: Can OSTTS03715B replace ED1110/3 in all applications?

A: OSTTS03715B is compatible with ED1110/3 for applications using wire gauges 12-22 AWG. If your design requires 10 AWG wire support, ED1110/3 is the required choice.

Q: What is the difference in contact material between these parts?

A: ED1110/3 uses copper tin alloy contacts; OSTTS03715B uses brass contacts. Both materials meet UL94 V-0 flammability requirements and maintain electrical performance at 300V and within the specified current range.

Q: Are there differences in housing material?

A: ED1110/3 features polyamide (PA) nylon housing; OSTTS03715B uses brass housing. Both materials satisfy flammability and environmental compliance requirements for this connector class.

Q: Do the screw torque specifications affect substitution?

A: ED1110/3 specifies 0.5 Nm (4.4 Lb-In) torque; OSTTS03715B specifies 0.4 Nm (4.6 Lb-In). Both values are within acceptable fastening ranges for this connector type and do not prevent substitution.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both ED1110/3 and OSTTS03715B are RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What wire gauge range should I use for compatibility?

A: For guaranteed compatibility between both parts, use wire gauges 12-22 AWG. ED1110/3 additionally supports 10 AWG; OSTTS03715B additionally supports 23-24 AWG.

Q: Are both parts actively manufactured?

A: Yes. Both ED1110/3 and OSTTS03715B maintain Active product status with current inventory availability.
