OSTOP162200 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTOP162200 is a 16-position terminal block header manufactured by On Shore Technology Inc., designed for vertical solder mounting applications. This component features male pins in an unshrouded configuration with a 0.138" (4.60mm) pitch, rated for 300V UL operation. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative mounting or housing materials.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP162200 is determined by strict alignment of the following critical parameters:

• Position Count & Configuration: 16 positions, single level, 16 positions per level
• Pitch Specification: 0.138" (4.60mm) center-to-center spacing
• Connector Type: Header with male pins, unshrouded design
• Orientation: Vertical mounting configuration
• Voltage Rating: Minimum 300V UL compliance
• Contact Finish: Tin plating for mating surfaces
• Regulatory Compliance: ROHS3 Compliant status

The substitute part 1945232 (Phoenix Contact COMBICON PST series) meets all critical substitution criteria. Differences in mounting method (solder vs. through-hole), housing material (brass vs. polyamide), and contact tail geometry do not preclude substitution when the application design accommodates these variations.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTOP162200 and 1945232 maintain ROHS3 compliance and identical moisture sensitivity ratings, qualifying them for equivalent use in applications requiring regulatory adherence. The primary selection criterion depends on PCB design accommodation:

• OSTOP162200 is specified for solder mounting with a compact profile (0.138" insulation height), suitable for space-constrained layouts with direct solder termination to PCB pads.

• 1945232 employs through-hole mounting with increased insulation height (0.512"), providing mechanical robustness and rework capability. The polyamide housing offers enhanced material properties compared to brass.

Selection between these parts is determined by the PCB design's mounting hole pattern, available vertical clearance, and termination method compatibility. Both parts carry active product status and maintain equivalent electrical performance at 300V UL rating.

Frequently Asked Questions (FAQ)

Q: Can the 1945232 directly replace the OSTOP162200 on an existing PCB?

A: Direct replacement requires PCB design verification. The OSTOP162200 uses solder mounting, while the 1945232 requires through-hole mounting. PCB pad patterns and hole diameters must accommodate the 1945232's through-hole configuration. Insulation height difference (0.138" vs. 0.512") may affect vertical clearance constraints.

Q: Are the electrical ratings equivalent between these parts?

A: Yes. Both parts are rated for 300V UL operation, support 16-position configuration at 0.138" (4.60mm) pitch, and feature tin-plated mating surfaces. Electrical performance is equivalent for applications within these specifications.

Q: What is the significance of the housing material difference?

A: The OSTOP162200 uses brass housing, while the 1945232 uses polyamide (nylon). Polyamide provides superior insulation properties and flame resistance (UL94 V-0 rating on the 1945232). Material selection depends on application thermal and mechanical requirements.

Q: Does the contact tail length difference affect compatibility?

A: The 0.012" (0.31mm) difference in contact tail length (0.138" vs. 0.150") is minor and does not affect electrical compatibility. However, mounting method differences (solder vs. through-hole) are the primary design consideration.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, supporting deployment in standard industrial and commercial applications. Specific high-reliability requirements should be evaluated against application standards and environmental conditions.
