OSTEP020000 Equivalent & Substitute Parts

Part Overview

The OSTEP020000 is a 2-position terminal block header manufactured by On Shore Technology Inc., featuring male pins in an unshrouded configuration with 0.197" (5.00mm) vertical pitch and solder mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility, mechanical fit, and performance characteristics within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEP020000 is determined by strict alignment with the following critical parameters:

• Electrical Compatibility: Voltage rating of 300 V UL minimum; current rating sufficient for application requirements
• Mechanical Compatibility: 2-position configuration; 0.197" (5.00mm) pitch; vertical orientation; male pin unshrouded type
• Thermal Compatibility: Operating temperature range of -30°C to 105°C or broader
• Regulatory Compliance: RoHS compliance status; REACH unaffected designation; MSL rating of 1 or equivalent
• Mounting Interface: Solder or through-hole termination compatible with PCB design

The substitute part 31027102 (METZ CONNECT USA Inc.) qualifies as an equivalent based on matching electrical ratings, mechanical configuration, pitch specification, and regulatory compliance. Differences in mounting type (through-hole vs. solder) and contact tail dimensions represent design variations within the same functional category and do not preclude substitution when PCB layout accommodates the through-hole termination method.

Parameter Comparison

Engineering Selection Recommendations

The 31027102 (METZ CONNECT USA Inc.) is qualified as a direct functional substitute for the obsolete OSTEP020000 based on the following engineering criteria:

Electrical Equivalence: Both components maintain 300 V UL voltage rating and support the same electrical interface specifications. The substitute provides an explicit 15 A current rating, establishing a defined current capacity for the application.

Mechanical Equivalence: Identical 2-position configuration, 0.197" (5.00mm) pitch, vertical orientation, and male pin unshrouded type ensure mechanical compatibility with mating connectors and PCB layouts designed for the original part.

Regulatory Compliance: Both components meet RoHS compliance requirements and maintain REACH unaffected status. MSL rating of 1 (Unlimited) for both parts ensures equivalent moisture handling and storage requirements.

Thermal Performance: The substitute's operating temperature range of -40°C to 105°C encompasses the original specification of -30°C to 105°C, providing equivalent or superior thermal performance.

Design Consideration: The primary design difference is termination method (through-hole vs. solder). PCB layout must accommodate the through-hole mounting configuration of the substitute. Contact tail length (0.134" vs. 0.157") and insulation height (0.073" vs. 0.157") represent dimensional variations that require verification against specific PCB hole sizing and clearance specifications.

Procurement Status: The substitute is in active production with confirmed inventory availability (1696 pcs), ensuring supply chain continuity for the obsolete OSTEP020000.

Frequently Asked Questions (FAQ)

Q: Can the 31027102 be used as a direct replacement for OSTEP020000 in existing designs?

A: The 31027102 qualifies as a functional equivalent based on electrical rating, pitch, position count, and orientation. However, the through-hole termination method differs from the original solder mounting. PCB design must accommodate through-hole pads. Contact tail length and insulation height differences require verification against specific PCB hole specifications and clearance requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: number of positions (2), pitch (0.197"/5.00mm), header orientation (vertical), pin type (male, unshrouded), voltage rating (300 V minimum), operating temperature range compatibility, and regulatory compliance (RoHS, REACH, MSL). Mounting type and contact dimensions are secondary considerations dependent on PCB design.

Q: Does the substitute provide better performance than the original part?

A: The 31027102 provides an explicit 15 A current rating, whereas the original OSTEP020000 does not specify current capacity. The substitute's operating temperature range extends to -40°C, providing broader low-temperature performance. Both components meet identical voltage, pitch, and regulatory requirements.

Q: Are there any compliance or certification differences between the parts?

A: Both components are RoHS compliant and REACH unaffected. MSL ratings are identical (1 - Unlimited). The substitute is in active production status, whereas the original is obsolete. No compliance disadvantages exist with the substitute.

Q: What design considerations are necessary when switching from OSTEP020000 to 31027102?

A: PCB layout must be modified to accommodate through-hole termination instead of solder mounting. Hole diameter and spacing must align with the substitute's pin specifications. Contact tail length (0.134" vs. 0.157") and insulation height (0.073" vs. 0.157") must be verified against PCB clearance and hole depth requirements. Mating connector compatibility should be confirmed based on pin length and spacing.
