OSTEP080000 Equivalent & Substitute Parts

Part Overview

The OSTEP080000 is an 8-position terminal block header manufactured by On-Shore Technology, featuring male pins in an unshrouded vertical configuration with 5.00mm pitch. This component is designed for solder mounting applications and operates across a temperature range of -30°C to 105°C with a rated voltage of 300V UL.

The OSTEP080000 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEP080000 is determined by the following critical parameters:

• Number of Positions: 8 positions (fixed requirement)
• Pitch: 0.197" (5.00mm) (fixed requirement)
• Header Orientation: Vertical (fixed requirement)
• Type: Header, Male Pins, Unshrouded (fixed requirement)
• Voltage Rating: 300V UL minimum (fixed requirement)
• Operating Temperature Range: Must accommodate -30°C to 105°C minimum
• Mounting Compatibility: Solder or through-hole mounting acceptable for PCB integration
• Compliance: RoHS and REACH compliance preferred for modern applications

The substitute part 31017108 (METZ CONNECT USA Inc.) satisfies all critical electrical and mechanical parameters. While mounting type differs (through-hole versus solder), both termination methods provide equivalent PCB integration capability for 8-position, 5.00mm pitch vertical headers with male pins.

Parameter Comparison

Engineering Selection Recommendations

The 31017108 from METZ CONNECT USA Inc. is a direct functional substitute for the obsolete OSTEP080000. Both components meet the 300V UL voltage requirement, maintain 8-position configuration at 5.00mm pitch, and support vertical male pin header applications.

The 31017108 offers the advantage of active product status, ensuring ongoing availability and supply chain support. The component maintains RoHS compliance and extends the operating temperature range to -40°C, providing additional thermal margin beyond the original specification.

The primary design consideration is the transition from solder mounting (OSTEP080000) to through-hole mounting (31017108). Both termination methods are standard PCB integration techniques. The through-hole approach of the substitute part may require PCB layout modification if the original design utilized surface-mount solder pads. Contact tail length and insulation height differences are within acceptable tolerances for standard PCB hole spacing and clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 31017108 directly replace the OSTEP080000 without PCB modification?

A: Electrical and mechanical compatibility is confirmed across all critical parameters. However, PCB layout modification may be required due to the difference between solder mounting and through-hole mounting. Verify that your PCB design accommodates through-hole pin insertion and plating specifications.

Q: Are there differences in contact material that affect performance?

A: The OSTEP080000 uses tin contact mating finish, while the 31017108 uses silver. Both finishes are standard for terminal block applications and provide equivalent electrical performance at 300V. Silver contacts offer superior corrosion resistance in high-humidity environments.

Q: Does the operating temperature range difference impact compatibility?

A: The 31017108 extends the lower operating temperature to -40°C compared to the OSTEP080000 at -30°C. This provides additional thermal margin and does not restrict compatibility for applications within the original -30°C to 105°C range.

Q: What is the significance of the contact tail length and insulation height differences?

A: The OSTEP080000 has a contact tail length of 0.157" (4.00mm) and insulation height of 0.157" (4.00mm). The 31017108 has a contact tail length of 0.134" (3.40mm) and insulation height of 0.073" (1.85mm). These dimensions are design parameters for through-hole versus solder mounting. Confirm PCB hole depth and clearance specifications match the substitute part dimensions.

Q: Is the 31017108 RoHS compliant?

A: Yes, the 31017108 is RoHS compliant. Both the original OSTEP080000 (ROHS3 Compliant) and substitute part meet RoHS requirements for modern applications.

Q: What is the current rating difference between these parts?

A: The OSTEP080000 does not specify a current rating. The 31017108 is rated for 15A UL. For applications requiring current specifications, the 31017108 provides a defined 15A capacity suitable for standard terminal block applications.
