OSTTS11515B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS11515B is an 11-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 become necessary when inventory constraints occur, when specific wire gauge requirements differ from standard specifications, or when alternative contact material compositions are required for particular application environments.

Key Parameters

Substitute Part Grouping Explanation

The EDZ1110/11 qualifies as a direct substitute for the OSTTS11515B based on the following critical parameters:

Matching Parameters:

• 11-position configuration with identical pitch spacing (0.200" / 5.08mm)
• Female socket plug type with screw termination
• Free-hanging (in-line) mounting orientation
• Identical voltage rating (300 V UL)
• Operating temperature range (-30°C ~ 105°C)
• UL94 V-0 flammability rating
• Active product status with ROHS3 compliance and REACH unaffected designation

Allowable Variations:

• Wire gauge range: EDZ1110/11 accepts 10-22 AWG (versus 12-24 AWG for OSTTS11515B), providing broader compatibility for smaller gauge conductors
• Contact material: EDZ1110/11 uses Copper Tin Alloy versus Brass in the main part
• Housing material: EDZ1110/11 uses Polyamide (PA), Nylon versus Brass housing
• Screw torque specification: 0.5 Nm (4.4 Lb-In) versus 0.4 Nm (4.6 Lb-In)
• Wire strip length: 7mm versus 6-7mm range

These variations remain within acceptable substitution parameters for terminal block plug applications where mechanical and electrical performance requirements are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS11515B and EDZ1110/11 maintain active product status with identical regulatory compliance profiles (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on the following criteria:

OSTTS11515B Selection Criteria:

• Applications requiring brass contact and housing materials for specific corrosion resistance or conductivity requirements
• Wire gauge requirements strictly within the 12-24 AWG range
• Screw torque specification of 0.4 Nm (4.6 Lb-In) is critical to application assembly procedures

EDZ1110/11 Selection Criteria:

• Applications accommodating wire gauges as small as 10 AWG, providing expanded conductor size compatibility
• Polyamide (PA) nylon housing material acceptable for the application environment
• Copper Tin Alloy contact material suitable for electrical performance requirements
• Screw torque specification of 0.5 Nm (4.4 Lb-In) compatible with assembly procedures

Both parts satisfy identical voltage (300 V UL), temperature (-30°C ~ 105°C), and flammability (UL94 V-0) requirements. Substitution is permissible when regulatory compliance and electrical performance specifications align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can EDZ1110/11 replace OSTTS11515B in existing designs?

A: Yes, provided that the application accommodates the material differences (Copper Tin Alloy contacts and Polyamide housing versus Brass) and the expanded wire gauge range (10-22 AWG versus 12-24 AWG). Both parts maintain identical pitch spacing, position count, voltage rating, temperature range, and flammability classification.

Q: What is the significance of the wire gauge range difference?

A: The EDZ1110/11 accepts smaller gauge conductors (10 AWG minimum) compared to the OSTTS11515B (12 AWG minimum). This provides broader compatibility for applications using finer wire gauges. The maximum gauge remains within acceptable overlap at 22 AWG for EDZ1110/11 versus 24 AWG for OSTTS11515B.

Q: Are there material compatibility concerns with the housing material change?

A: The OSTTS11515B uses brass housing while EDZ1110/11 uses Polyamide (PA) nylon. Both materials maintain UL94 V-0 flammability ratings and operate across the identical temperature range (-30°C ~ 105°C). Material selection should be evaluated based on specific environmental exposure, mechanical stress, and chemical compatibility requirements of the application.

Q: How do the screw torque specifications differ?

A: The OSTTS11515B specifies 0.4 Nm (4.6 Lb-In) while EDZ1110/11 specifies 0.5 Nm (4.4 Lb-In). This 0.1 Nm difference reflects the different housing materials and contact configurations. Assembly procedures should follow the torque specification of the selected part to ensure proper termination.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both OSTTS11515B and EDZ1110/11 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What inventory considerations apply to these parts?

A: OSTTS11515B has 1097 pieces in stock while EDZ1110/11 has 1344 pieces in stock. Both are classified as new original inventory in bulk packaging.
