OSTTS07515B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS07515B is a 7-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with female sockets and 0.200" (5.08mm) pitch spacing. This component is classified as an active product with full RoHS3 compliance and REACH unaffected status. Alternative models may be required due to inventory constraints, application-specific wire gauge requirements, or sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS07515B is determined by the following critical parameters that must remain constant or compatible:

Number of Positions: Must equal 7
Pitch Spacing: Must equal 0.200" (5.08mm)
Type: Must be Plug with Female Sockets
Termination Style: Must be Screw
Mounting Type: Must be Free Hanging (In-Line)
Voltage Rating: Must meet or exceed 300 V UL
Operating Temperature Range: Must encompass -30°C ~ 105°C
Material Flammability Rating: Must meet UL94 V-0
Product Status: Must be Active
Regulatory Compliance: Must maintain RoHS3 and REACH unaffected status

Wire gauge compatibility is evaluated on an application-specific basis. The substitute part EDZ1110/7 meets all critical substitution criteria with documented differences in wire gauge range and contact material composition.

Engineering Selection Recommendations

Both the OSTTS07515B and EDZ1110/7 are active products with identical regulatory compliance profiles: RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both components maintain UL94 V-0 flammability ratings and operate across the identical temperature range of -30°C to 105°C at 300 V UL voltage rating.

The EDZ1110/7 substitute part differs in the following documented specifications: wire gauge range (10-22 AWG versus 12-24 AWG), contact material composition (Copper Tin Alloy versus Brass), housing material (Polyamide/Nylon versus Brass), screw torque specification (0.5 Nm versus 0.4 Nm), and wire strip length (7mm fixed versus 6-7mm range). These differences are material and must be evaluated against specific application requirements.

Selection between these parts is based on inventory availability, wire gauge compatibility with the target application, and material property requirements. Both parts satisfy the core electrical and mechanical substitution criteria for 7-position, 5.08mm pitch, screw-terminated, free-hanging terminal block plugs.

Frequently Asked Questions (FAQ)

Q: Can EDZ1110/7 be used as a direct replacement for OSTTS07515B?

A: EDZ1110/7 meets all critical substitution parameters: 7 positions, 0.200" (5.08mm) pitch, screw termination, free-hanging mounting, 300 V UL rating, -30°C to 105°C operating range, UL94 V-0 flammability, and identical regulatory compliance. Substitution is valid provided the application wire gauge falls within the 10-22 AWG range of the EDZ1110/7 and the material differences (Copper Tin Alloy contacts, Polyamide housing) are acceptable for the intended use.

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

A: The primary differences are wire gauge range (OSTTS07515B: 12-24 AWG; EDZ1110/7: 10-22 AWG), contact material (Brass versus Copper Tin Alloy), housing material (Brass versus Polyamide/Nylon), screw torque (0.4 Nm versus 0.5 Nm), and wire strip length specification (6-7mm range versus 7mm fixed).

Q: Are both parts RoHS3 compliant?

A: Yes, both OSTTS07515B and EDZ1110/7 are RoHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: What is the voltage rating for both parts?

A: Both parts are rated for 300 V UL.

Q: Do both parts operate in the same temperature range?

A: Yes, both parts operate across -30°C to 105°C.

Q: What is the pitch spacing for these terminal blocks?

A: Both parts feature 0.200" (5.08mm) pitch spacing with 7 positions per level.

Q: Are there any packaging differences?

A: Both parts are supplied in bulk packaging. Current inventory for OSTTS07515B is 830 pieces; current inventory for EDZ1110/7 is 780 pieces.
