OSTOP044200 Terminal Block Header - Equivalent & Substitute Parts
Part Overview
The OSTOP044200 is a 4-position terminal block header manufactured by On Shore Technology Inc., 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 OSTOP044200 carries an Obsolete product status. Identifying 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.

Substitute Part Grouping Explanation
Substitution eligibility for the OSTOP044200 is determined by the following critical parameters:
- Electrical Compatibility: 4-position configuration, 0.150" (3.81mm) pitch, 300V UL voltage rating, and male pin header type
- Physical Compatibility: Vertical orientation, unshrouded design, 0.138" (4.60mm) contact tail length
- Regulatory Compliance: ROHS3 compliance and MSL 1 rating
- Mounting Interface: Solder mounting capability
The substitute part OP0442000000G (Amphenol Anytek) satisfies these core substitution criteria through matching electrical ratings, pitch spacing, pin configuration, and regulatory certifications. Variations in housing material (Brass vs. Thermoplastic) and insulation height do not preclude functional equivalence within the specified electrical and mechanical parameters.

Engineering Selection Recommendations
The OP0442000000G represents a functionally equivalent substitute for the obsolete OSTOP044200 based on matching electrical specifications (4-position, 3.81mm pitch, 300V rating), identical pin configuration (male, unshrouded), and equivalent regulatory compliance (ROHS3, MSL 1).
The substitute part maintains active product status with Amphenol Anytek, ensuring ongoing availability and supply chain stability. Both components satisfy identical voltage and position requirements for terminal block header applications.
The OP0442000000G provides additional electrical performance data (10A UL current rating, -40°C ~ 115°C operating temperature range, UL94 V-0 flammability rating, and tin contact mating finish) not specified in the original OSTOP044200 documentation. These specifications represent enhanced or clarified performance characteristics suitable for direct replacement in existing designs.
Frequently Asked Questions (FAQ)
Q: Can OP0442000000G be used as a direct replacement for OSTOP044200?
A: Yes. Both components share identical electrical ratings (300V, 4-position, 3.81mm pitch), pin configuration (male, unshrouded), and regulatory compliance (ROHS3, MSL 1). The substitute part is actively manufactured and available.
Q: What is the difference in insulation height between these parts?
A: OSTOP044200 specifies 0.138" (4.60mm) insulation height, while OP0442000000G specifies 0.079" (2.00mm). This dimensional difference does not affect electrical compatibility or pitch-based mating characteristics.
Q: Are there differences in housing material?
A: OSTOP044200 uses brass housing; OP0442000000G uses thermoplastic housing. Both materials are suitable for the specified electrical and environmental ratings. Material selection does not impact functional equivalence for standard terminal block header applications.
Q: Does the mounting type difference affect compatibility?
A: OSTOP044200 is specified for solder mounting; OP0442000000G is specified for through-hole mounting. Both termination methods are compatible with standard PCB assembly processes and do not preclude functional substitution.
Q: Are both parts RoHS compliant?
A: Yes. Both OSTOP044200 and OP0442000000G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory requirements for electronic component manufacturing and assembly.
