EDZ1700/3 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The EDZ1700/3 is a 3-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with female sockets and 0.150" (3.81mm) pitch spacing. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative models become necessary when inventory constraints occur, when specific torque or contact material requirements differ for application-specific needs, or when sourcing from alternative product lines within the same manufacturer is required.

Substitute Part Grouping Explanation

The OSTTS03315A qualifies as a direct substitute based on the following critical parameters that determine functional interchangeability:

Identical electrical specifications: 300 V UL voltage rating, 16-28 AWG wire gauge capacity, 1.5mm² wire gauge range
Identical mechanical configuration: 3-position plug with female sockets, 0.150" (3.81mm) pitch, free-hanging (in-line) mounting
Identical termination method: Screw-based termination
Identical operating environment: -30°C ~ 105°C temperature range
Identical compliance status: ROHS3 compliant, REACH unaffected, EAR99 classification

Variations exist in torque specification (0.4 Nm vs. 0.2 Nm), wire strip length tolerance (7mm vs. 6-7mm), contact material (Copper Tin Alloy vs. Brass), and housing material (Polyamide vs. Brass). These differences do not prevent substitution when the application tolerates the specified torque range and material composition.

Engineering Selection Recommendations

Both EDZ1700/3 and OSTTS03315A maintain active product status with full RoHS3 compliance and REACH unaffected classification, ensuring regulatory alignment for current applications. Selection between these parts should be based on the following engineering criteria:

EDZ1700/3 is the primary choice when higher screw torque specification (0.4 Nm) is required for secure termination in high-vibration environments or when polyamide housing material is specified for the application.

OSTTS03315A is suitable as a substitute when lower screw torque (0.2 Nm) is acceptable and when brass contact and housing materials are compatible with the circuit design. This part offers equivalent electrical and mechanical performance within the specified torque range.

Both parts share identical voltage ratings, wire gauge capacity, pitch spacing, and operating temperature range, confirming functional interchangeability for standard 3-position screw-terminal applications.

Frequently Asked Questions (FAQ)

Q: Can OSTTS03315A directly replace EDZ1700/3 in existing designs?

A: Yes, OSTTS03315A is a direct substitute. Both parts share identical electrical specifications (300 V, 16-28 AWG), mechanical configuration (3-position, 0.150" pitch, free-hanging), and termination method (screw). The primary difference is screw torque specification (0.2 Nm vs. 0.4 Nm) and material composition (brass vs. polyamide housing).

Q: What is the significance of the torque difference between these parts?

A: EDZ1700/3 specifies 0.4 Nm screw torque, while OSTTS03315A specifies 0.2 Nm. This difference reflects the mechanical properties of the housing materials. Applications requiring higher torque retention should use EDZ1700/3. Applications with standard torque requirements can use OSTTS03315A without performance degradation.

Q: Are the contact materials interchangeable?

A: Both contact materials (Copper Tin Alloy in EDZ1700/3 and Brass in OSTTS03315A) are suitable for 300 V, 16-28 AWG applications. Material selection depends on application-specific corrosion resistance and conductivity requirements. Both materials are RoHS3 compliant.

Q: Do both parts support the same wire gauge range?

A: Yes. Both EDZ1700/3 and OSTTS03315A accept 16-28 AWG wire (1.5mm²), ensuring compatibility with identical conductor sizes.

Q: What is the wire strip length tolerance for each part?

A: EDZ1700/3 specifies 7mm wire strip length. OSTTS03315A specifies 6-7mm, providing a tolerance range. Both values are within acceptable limits for standard screw-terminal applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both EDZ1700/3 and OSTTS03315A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: EDZ1700/3 has 1117 pieces in stock. OSTTS03315A has 1368 pieces in stock. Both are available as new original components in bulk packaging.
