OSTOP094200 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTOP094200 is a 9-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 300V rated electrical connections.

The OSTOP094200 carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP094200 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 9 positions at 0.150" (3.81mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Configuration: Male pins in unshrouded format are required to match the original connector interface.
• Voltage Rating: Minimum 300V UL rating is mandatory for electrical safety equivalence.
• Mounting Interface: Contact tail length of 0.138" (4.60mm) ensures proper solder joint formation and PCB penetration depth.
• Compliance Standards: RoHS3 compliance and MSL 1 rating must be maintained for regulatory and environmental requirements.

The substitute part OP0942000000G (Amphenol Anytek) meets all critical substitution criteria while introducing a mounting type variation from solder to through-hole configuration, which represents a compatible enhancement for PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The OP0942000000G substitute part is electrically and mechanically compatible with the OSTOP094200 based on matching critical parameters: identical position count, pitch, voltage rating, and contact tail length. Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory requirements.

The OP0942000000G carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete OSTOP094200. The through-hole mounting configuration of the substitute part provides enhanced mechanical stability during PCB assembly and thermal cycling, while maintaining solder joint integrity through the specified contact tail length.

Housing material differs between the parts (Brass versus Thermoplastic), and the substitute provides additional electrical specifications (10A current rating, -40°C to 115°C operating temperature, UL94 V-0 flammability rating, and tin contact finish) that were not specified for the original part. These additional specifications represent enhanced documentation and performance characteristics rather than incompatibilities.

Frequently Asked Questions (FAQ)

Q: Can OP0942000000G be used as a direct replacement for OSTOP094200 in existing PCB designs?

A: Yes. Both parts share identical position count (9), pitch (0.150"/3.81mm), header orientation (vertical), pin configuration (male, unshrouded), voltage rating (300V), and contact tail length (0.138"/4.60mm). These parameters determine mechanical and electrical compatibility with mating connectors and PCB layouts. The through-hole mounting type of the substitute is compatible with standard PCB assembly processes.

Q: What are the key differences between these parts?

A: The primary differences are product status (Obsolete versus Active), mounting type (solder versus through-hole), housing material (Brass versus Thermoplastic), and the availability of additional electrical specifications on the substitute part. These differences do not affect functional compatibility for the specified application.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTOP094200 and OP0942000000G are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory standards.

Q: What is the significance of the contact tail length specification?

A: The contact tail length of 0.138" (4.60mm) determines the depth of PCB penetration and solder joint formation. Matching this specification between the original and substitute part ensures proper electrical connection and mechanical retention on the printed circuit board.

Q: Does the housing material change affect performance?

A: Housing material differences (Brass versus Thermoplastic) do not affect electrical performance for this application. Both materials provide adequate insulation and structural support. The thermoplastic housing of the substitute part may offer improved dimensional stability and cost efficiency in high-volume production scenarios.
