Key Parameters

Substitute Part Grouping Explanation

Substitute terminal blocks for the 1-1776253-9 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Pitch: 0.138" (3.50mm) — ensures PCB footprint compatibility
• Mating Orientation: Vertical with Board — maintains mechanical fit
• Mounting Type: Through Hole — preserves assembly method
• Wire Termination: Screw - Rising Cage Clamp — ensures wire connection compatibility
• Number of Levels: 1 — confirms single-level configuration

Secondary Compatibility Parameters:

• Positions Per Level: 19 positions (exact match) or 18 positions (reduced capacity)
• Current Rating: Minimum 7 A (substitute ratings of 10 A exceed requirement)
• Voltage Rating: Minimum 250 V (substitute ratings of 300 V exceed requirement)
• Wire Gauge: Overlap within 18-26 AWG range (substitute range 16-24 AWG provides compatibility)
• Operating Temperature: Minimum -55°C to 105°C (substitute range -30°C to 105°C provides partial coverage)

The substitute parts OSTER180151 and OSTER190151 from On Shore Technology Inc. meet the primary matching criteria and provide equal or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

OSTER190151 — Primary Substitute

The OSTER190151 provides the most direct substitution for the 1-1776253-9. Both components feature identical 19-position capacity and 0.138" (3.50mm) pitch, ensuring direct PCB footprint compatibility without layout modifications. The OSTER190151 carries active product status with ROHS3 compliance and REACH unaffected certification, supporting long-term supply chain availability and regulatory compliance requirements. Electrical ratings of 10 A and 300 V exceed the original specification, providing design margin. The operating temperature range of -30°C to 105°C covers the upper requirement but does not extend to the -55°C lower limit of the original part.

OSTER180151 — Secondary Substitute

The OSTER180151 serves as an alternative when 18-position capacity is acceptable for the application. This component shares identical pitch, mating orientation, and mounting characteristics with the main part. The 18-position configuration requires PCB layout modification to accommodate one fewer connection point. Like the OSTER190151, the OSTER180151 is active, ROHS3 compliant, and REACH unaffected. Electrical performance exceeds the original specification with 10 A current and 300 V voltage ratings.

Compliance and Availability Considerations

Both substitute parts are manufactured by On Shore Technology Inc. and maintain active product status, ensuring ongoing availability and technical support. Both substitutes comply with ROHS3 requirements and carry REACH unaffected status, supporting regulatory compliance in regulated markets. The original 1-1776253-9 carries obsolete status, making transition to an active substitute necessary for new production or long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the OSTER190151 replace the 1-1776253-9 without PCB modifications?

A: Yes. Both components feature 19 positions and 0.138" (3.50mm) pitch, providing identical PCB footprint compatibility. No layout changes are required for direct substitution.

Q: What is the key difference between OSTER180151 and OSTER190151?

A: The OSTER180151 provides 18 positions while the OSTER190151 provides 19 positions. The OSTER190151 matches the original part's position count. Selection between these substitutes depends on whether the application requires all 19 connection points.

Q: Are the substitute parts rated for the same electrical specifications as the original?

A: The substitute parts exceed the original electrical specifications. The 1-1776253-9 is rated at 7 A and 250 V, while both OSTER substitutes are rated at 10 A and 300 V. These higher ratings provide design margin and are compatible with applications designed for the original part's specifications.

Q: Does the operating temperature range differ between the main part and substitutes?

A: Yes. The 1-1776253-9 operates from -55°C to 105°C, while both OSTER substitutes operate from -30°C to 105°C. The substitutes do not extend to the -55°C lower limit. Applications requiring operation below -30°C require evaluation of alternative solutions.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both OSTER180151 and OSTER190151 are ROHS3 compliant and REACH unaffected. The original 1-1776253-9 carries "Not applicable" RoHS status and "Vendor Undefined" REACH status, making the substitutes preferable for regulated applications.

Q: What wire gauge range do the substitute parts accept?

A: The OSTER substitutes accept 16-24 AWG wire, compared to the original part's 18-26 AWG range. The substitutes accommodate larger gauge wire (16 AWG) but do not support the finest gauge (26 AWG) of the original specification. Applications using 25-26 AWG wire require alternative solutions.

Q: Can I use these substitutes in new production designs?

A: Yes. Both OSTER substitutes carry active product status, ensuring availability for new production. The original 1-1776253-9 is obsolete and not recommended for new designs. Substitutes provide long-term supply assurance and regulatory compliance support.

Q: What is the packaging format for the substitute parts?

A: Both OSTER180151 and OSTER190151 are supplied in bulk packaging, with 1043 and 940 pieces in stock respectively.
