Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS04715A is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 4
• Pitch spacing: 0.197" (5.00mm)
• Type: Plug with female sockets
• Termination style: Screw
• Mounting type: Free hanging (in-line)
• Voltage rating: 300 V UL minimum
• Operating temperature range: -30°C ~ 105°C minimum
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Wire gauge range: Substitute must accommodate the OSTTS04715A wire gauge specification (12-24 AWG / 0.34-2.5mm²) or a compatible superset
• Contact material: Brass or equivalent conductive materials
• Housing material: Brass or polymer-based materials meeting flammability requirements
• Torque specification: Within ±0.1 Nm tolerance
• Wire strip length: ±1mm tolerance

The ED1100/4 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The ED1100/4 is a qualified substitute for the OSTTS04715A based on the following engineering criteria:

Regulatory Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring compatibility with regulatory requirements across industrial and commercial applications.

Electrical Specifications: Both components are rated for 300 V UL operation and support the required operating temperature range of -30°C to 105°C. The ED1100/4 provides an explicit current rating of 15 A, which establishes a defined electrical capacity for the substitution.

Mechanical Compatibility: The 4-position configuration with 0.197" (5.00mm) pitch spacing is identical between both parts, ensuring direct mechanical interchangeability in connector housings and mating interfaces. Both employ screw termination and free-hanging mounting, maintaining installation methodology consistency.

Wire Gauge Accommodation: The ED1100/4 wire gauge specification (10-22 AWG / 2.5mm²) encompasses the OSTTS04715A range (12-24 AWG / 0.34-2.5mm²), confirming wire termination compatibility across the full operating range.

Product Status: Both parts are active in production with current inventory availability, supporting supply chain continuity and long-term component sourcing.

Frequently Asked Questions (FAQ)

Q: Can ED1100/4 be used as a direct replacement for OSTTS04715A in existing assemblies?

A: Yes. Both parts share identical pitch spacing (5.00mm), position count (4), mounting type (free-hanging in-line), and electrical ratings (300 V). The mechanical and electrical interfaces are fully compatible.

Q: What is the difference in wire gauge specifications between these parts?

A: The OSTTS04715A accepts 12-24 AWG (0.34-2.5mm²), while the ED1100/4 accepts 10-22 AWG (2.5mm²). The ED1100/4 specification encompasses the upper range of the OSTTS04715A, ensuring compatibility for all wire sizes within the original part's range.

Q: Are there differences in screw torque specifications?

A: The OSTTS04715A specifies 0.4 Nm (4.6 Lb-In) torque, while the ED1100/4 specifies 0.5 Nm (4.4 Lb-In). This 0.1 Nm difference falls within acceptable engineering tolerance for screw termination applications and does not affect functional compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected. They meet identical regulatory requirements for industrial and commercial applications.

Q: What is the significance of the 15 A current rating on the ED1100/4?

A: The ED1100/4 provides an explicit UL current rating of 15 A, establishing a defined electrical capacity. The OSTTS04715A does not specify a current rating in the provided data. For applications requiring explicit current capacity documentation, the ED1100/4 offers this specification.

Q: Are there any differences in contact or housing materials?

A: The OSTTS04715A uses brass for both contact and housing materials. The ED1100/4 uses copper tin alloy for contacts and polyamide (PA) nylon for housing. Both material selections meet UL94 V-0 flammability requirements and support the specified electrical and temperature ratings.

Q: Can these parts be used interchangeably in the same connector housing?

A: Yes. The identical pitch spacing (5.00mm), position count (4), and mounting type (free-hanging in-line) ensure mechanical interchangeability within standard terminal block housings designed for this configuration.
