Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTJ167152 is determined by the following critical parameters:

Position Count & Pitch Compatibility: The substitute part must maintain 16 positions with pitch spacing within acceptable mechanical tolerance. The OSTTJ167152 operates at 0.197" (5.00mm) pitch; the substitute part 1778124 operates at 0.200" (5.08mm) pitch, representing a 0.03mm variance. This minor pitch difference falls within standard connector mating tolerances for free-hanging inline applications.

Electrical Ratings: Both parts must meet or exceed the UL voltage requirement of 300 V. The OSTTJ167152 is rated 300 V UL; substitute 1778124 is rated 300 V UL and 630 V IEC, satisfying this criterion.

Termination Method: Both parts employ screw-based termination, ensuring compatible wire connection procedures. The OSTTJ167152 uses standard screw termination; 1778124 uses screw with rising cage clamp technology, which maintains backward compatibility with standard screw wire insertion.

Wire Gauge Compatibility: The OSTTJ167152 accepts 12-24 AWG (0.34-2.5mm²). The substitute 1778124 accepts 12-30 AWG (0.2-2.5mm²), providing expanded wire gauge range while maintaining overlap in the 12-24 AWG specification.

Mounting Configuration: Both parts are configured as free-hanging (in-line) plugs with female sockets, ensuring mechanical interchangeability in identical mounting environments.

Compliance & Material Standards: Both parts are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected, meeting identical regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTJ167152 and substitute part 1778124 maintain Active product status with full ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts is based on supply availability and application-specific requirements:

OSTTJ167152 Selection: Choose this part when the original specification requires exact 0.197" (5.00mm) pitch spacing and when existing connector housings or mating interfaces are designed specifically for this pitch dimension. Current inventory of 841 units supports immediate procurement.

1778124 Selection: Choose this substitute when supply constraints affect OSTTJ167152 availability or when the application permits the 0.200" (5.08mm) pitch variant. The rising cage clamp termination technology provides enhanced wire retention characteristics. Current inventory of 2093 units provides extended availability. The expanded wire gauge range (12-30 AWG) accommodates applications requiring smaller gauge conductors.

Both parts satisfy identical voltage (300 V UL), temperature (-30°C ~ 105°C), and regulatory requirements. The 0.03mm pitch difference is within standard connector tolerance specifications for free-hanging inline applications.

Frequently Asked Questions (FAQ)

Q: What is the pitch difference between OSTTJ167152 and 1778124, and does it affect compatibility?

A: The OSTTJ167152 operates at 0.197" (5.00mm) pitch, while 1778124 operates at 0.200" (5.08mm) pitch. The 0.03mm variance falls within standard mechanical tolerance for terminal block connectors. Compatibility depends on whether the mating connector housing or PCB footprint is designed for the specific pitch. If the application uses a dedicated mating connector, verify that connector's pitch specification before substitution.

Q: Are the screw torque specifications equivalent between these parts?

A: The OSTTJ167152 specifies 0.56 Nm (5.0 Lb-In) torque. The 1778124 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) torque. The 1778124 range encompasses the OSTTJ167152 specification, ensuring compatible installation procedures.

Q: Can I use 1778124 if my application requires 12-24 AWG wire?

A: Yes. The 1778124 accepts 12-30 AWG (0.2-2.5mm²), which includes the full 12-24 AWG range required by the OSTTJ167152. Wire gauge compatibility is maintained.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: Both termination methods are screw-based. The rising cage clamp technology in 1778124 provides enhanced wire retention through a spring-loaded mechanism that engages as the screw is tightened. Standard screw termination in OSTTJ167152 uses direct screw compression. Both methods are functionally equivalent for wire connection security.

Q: Are both parts suitable for the same operating temperature range?

A: The OSTTJ167152 specifies -30°C ~ 105°C operating temperature. The 1778124 does not specify an operating temperature range in the provided data. Verify the 1778124 operating temperature specification with the manufacturer if temperature extremes are critical to your application.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and carry identical EAR99 ECCN and HTSUS classifications.
