OSTOP174200 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTOP174200 is a 17-position terminal block header manufactured by On-Shore Technology, featuring male pins in an unshrouded configuration with 0.150" (3.81mm) vertical pitch spacing. This component is designed for solder mounting applications requiring reliable electrical interconnection in industrial and commercial equipment.

The OSTOP174200 carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP174200 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 17 positions at 0.150" (3.81mm) spacing (non-negotiable for mechanical fit)
• Connector Type: Header with male pins, unshrouded configuration
• Orientation: Vertical mounting
• Voltage Rating: Minimum 300 V UL rating
• Mounting Interface: Solder or through-hole termination compatible with PCB assembly
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part OP1742000000G (Amphenol Anytek) satisfies all critical substitution criteria. While minor differences exist in housing material (thermoplastic vs. brass) and insulation height, these variations remain within acceptable engineering tolerances for equivalent functional performance in the specified application category.

Parameter Comparison

Engineering Selection Recommendations

The OP1742000000G from Amphenol Anytek is a qualified substitute for the obsolete OSTOP174200. Both components maintain identical electrical specifications (300 V UL rating), mechanical configuration (17 positions, 0.150" pitch, vertical orientation), and regulatory compliance (ROHS3 Compliant, EAR99 classification).

The OP1742000000G carries Active product status, ensuring long-term availability and supply chain continuity. The substitute part provides additional technical specifications including 10 A current rating and -40°C to 115°C operating temperature range, which were not documented for the original part.

Physical differences between the two parts are minor: the substitute features thermoplastic housing instead of brass, and reduced insulation height (0.079" vs. 0.138"). These variations do not compromise functional equivalence for standard terminal block header applications.

Frequently Asked Questions (FAQ)

Q: Can OP1742000000G be used as a direct replacement for OSTOP174200?

A: Yes. Both parts share identical position count (17), pitch spacing (0.150"), connector type (male pins, unshrouded), orientation (vertical), and voltage rating (300 V UL). The substitute is electrically and mechanically compatible for equivalent applications.

Q: What is the difference in mounting between these parts?

A: The OSTOP174200 is specified for solder mounting. The OP1742000000G is rated for through-hole mounting. Both termination methods are compatible with standard PCB assembly processes and provide equivalent electrical performance.

Q: Does the housing material difference affect performance?

A: The OSTOP174200 uses brass housing while the OP1742000000G uses thermoplastic housing. Both materials meet the specified voltage rating (300 V) and regulatory requirements (ROHS3 Compliant). Material selection does not impact functional equivalence for this component category.

Q: Why is the insulation height different?

A: The OSTOP174200 specifies 0.138" insulation height while the OP1742000000G specifies 0.079". This difference reflects design variations between manufacturers but does not affect electrical performance or mechanical compatibility in standard terminal block applications.

Q: Is the substitute part currently available?

A: Yes. The OP1742000000G carries Active product status with documented inventory availability (1081 pcs), whereas the original OSTOP174200 is Obsolete. The substitute ensures reliable supply chain access for ongoing production requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the OSTOP174200 and OP1742000000G are ROHS3 Compliant and carry EAR99 classification, meeting current regulatory requirements for electronic component manufacturing and distribution.
