OSTOP032200 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTOP032200 is a 3-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 3.5mm pitch and is rated for 300V UL operation. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Terminal block headers are essential interconnect components used in industrial control systems, power distribution modules, and signal routing applications where reliable vertical mounting and solder termination are required. Alternative equivalent parts may be necessary due to inventory constraints, lead time considerations, or specific application requirements for enhanced mechanical or electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1945106 qualifies as a direct equivalent substitute based on the following critical parameters:

Matching Parameters:

• Number of positions: 3
• Pitch: 0.138" (3.50mm)
• Header orientation: Vertical
• Type: Header, Male Pins, Unshrouded
• Voltage rating: 300V UL (meets or exceeds OSTOP032200 specification)
• Contact mating finish: Tin
• RoHS3 compliance: Yes
• MSL rating: 1 (Unlimited)

Functional Equivalence Basis: Both components share identical positional configuration, pitch spacing, and vertical mounting orientation. The substitute part maintains equivalent electrical performance with UL voltage ratings of 300V and provides enhanced current capacity (10A UL vs. unspecified for main part). The through-hole mounting type of the substitute offers mechanical robustness equivalent to the solder mounting of the main part for terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTOP032200 and Phoenix Contact 1945106 are active production components with full RoHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent selection in terminal block header applications.

The OSTOP032200 features solder mounting termination with brass housing construction. The Phoenix Contact 1945106 substitute provides through-hole mounting with polyamide housing and enhanced mechanical specifications including greater insulation height (0.512" vs. 0.138") and specified current capacity (10A UL). Both components maintain identical pitch spacing (3.5mm), positional configuration (3-position), and vertical orientation required for direct functional substitution.

Selection between these components should be based on specific PCB design requirements regarding mounting method (solder vs. through-hole) and mechanical clearance constraints. The substitute part's increased insulation height may require design consideration in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1945106 directly replace the OSTOP032200 in existing designs?

A: Direct replacement is possible when PCB design accommodates through-hole mounting instead of solder mounting. The identical 3.5mm pitch and 3-position configuration ensure electrical and mechanical compatibility. Design review is required to confirm mounting method compatibility and clearance for the substitute's increased insulation height (0.512" vs. 0.138").

Q: What are the key compatibility criteria for these terminal block headers?

A: Critical compatibility parameters are: 3-position configuration, 0.138" (3.50mm) pitch spacing, vertical orientation, male pin unshrouded type, and 300V UL voltage rating. Both components meet these specifications and maintain tin contact mating finish for equivalent electrical performance.

Q: Are there differences in current handling capacity between these parts?

A: The Phoenix Contact 1945106 specifies 10A UL current capacity, while the OSTOP032200 does not provide current specification in available documentation. For applications requiring specified current ratings, the substitute part provides documented 10A capacity at 300V UL.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OSTOP032200 and Phoenix Contact 1945106 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

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

A: The OSTOP032200 uses brass housing while the Phoenix Contact 1945106 uses polyamide (PA) nylon. Both materials are suitable for terminal block applications. Polyamide housing in the substitute provides enhanced insulation properties and flammability rating (UL94 V-0), while brass housing in the main part offers different mechanical characteristics. Material selection should align with specific application thermal and mechanical requirements.
