OSTTO130152 Equivalent & Substitute Parts

Part Overview

The OSTTO130152 is a 13-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with side entry wire connections. This component operates at 300V with a 10A current rating and accommodates wire gauges from 16-26 AWG using screw-based rising cage clamp termination. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent parts may be required due to supply constraints, design revisions, or regional availability considerations while maintaining functional compatibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 3-282837-2 qualifies as a functional equivalent based on the following substitution criteria:

Critical Matching Parameters:

13-position configuration maintained
Horizontal with board mating orientation preserved
Through-hole mounting type consistent
Screw-based rising cage clamp termination method identical
Side entry interlocking feature present
300V voltage rating matched
RoHS3 compliance maintained
Unlimited moisture sensitivity level (MSL 1) consistent

Allowable Parameter Variations:

Pitch tolerance: 0.197" (5.00mm) to 0.200" (5.08mm) — within standard PCB layout accommodation
Current rating: 10A to 13.5A — substitute exceeds minimum requirement
Wire gauge: 16-26 AWG to 16-28 AWG — substitute accommodates broader range
Screw torque: 0.4 Nm to 0.68 Nm — substitute specification higher but compatible with standard assembly practices

Engineering Selection Recommendations

Both the OSTTO130152 and 3-282837-2 maintain active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings, making either suitable for new designs and production environments. The OSTTO130152 remains the primary specification for existing designs. The 3-282837-2 substitute provides equivalent electrical performance with enhanced current capacity (13.5A versus 10A) and extended wire gauge accommodation (16-28 AWG versus 16-26 AWG), supporting broader application flexibility. PCB layout verification is necessary due to the 0.03" (0.08mm) pitch difference to confirm mounting hole alignment with existing footprints. Both parts carry identical voltage and temperature ratings, ensuring thermal and electrical performance parity across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the 3-282837-2 be used as a direct replacement for OSTTO130152 in existing PCB designs?

A: The 3-282837-2 is functionally equivalent but requires PCB layout verification. The pitch difference of 0.03" (0.08mm) may require footprint adjustment depending on design tolerances. All 13 mounting holes must align with existing PCB traces and vias.

Q: What are the key electrical differences between these parts?

A: The 3-282837-2 provides higher current capacity (13.5A versus 10A) and accommodates a broader wire gauge range (16-28 AWG versus 16-26 AWG). Both maintain 300V voltage rating and identical temperature operating range.

Q: Are both parts RoHS3 compliant?

A: Yes, both OSTTO130152 and 3-282837-2 are RoHS3 compliant with unlimited moisture sensitivity ratings (MSL 1).

Q: What is the significance of the pitch tolerance between these parts?

A: The pitch difference of 0.03" (0.08mm) is within standard PCB manufacturing tolerances but requires verification against existing board layouts. This difference may affect mounting hole spacing and should be confirmed before design implementation.

Q: Can wire gauge differences affect installation procedures?

A: The 3-282837-2 accommodates 16-28 AWG wire, compared to 16-26 AWG for the OSTTO130152. This broader range does not affect installation but allows flexibility for thinner wire applications. Screw torque specifications differ (0.68 Nm versus 0.4 Nm) and should be observed during assembly.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant, carry EAR99 ECCN classification, and fall under HTSUS code 8536.90.4000. The OSTTO130152 is REACH unaffected, while the 3-282837-2 is REACH affected.
