OSTEP230000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTEP230000 is a 23-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 termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates within a temperature range of -30°C to 105°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTEP230000 is determined by strict equivalence across the following critical parameters:

• Position Count: 23 positions (non-negotiable)
• Pitch Specification: 0.197" (5.00mm) center-to-center spacing
• Header Configuration: Male pins, unshrouded design
• Orientation: Vertical mounting
• Voltage Rating: 300 V minimum (UL standard)
• Termination Method: Solder-compatible interface
• Compliance: ROHS3 and REACH compliance maintained

The substitute part OP2300000000G from Amphenol Anytek satisfies all critical substitution criteria. While this part transitions from solder-only termination to through-hole mounting and introduces enhanced electrical specifications (12A IEC / 15A UL current ratings), the core functional parameters remain compatible for direct substitution in applications requiring the OSTEP230000.

Parameter Comparison

Engineering Selection Recommendations

The OP2300000000G substitute part is suitable for direct replacement of the obsolete OSTEP230000 based on the following engineering criteria:

Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance Alignment: Both parts maintain identical ROHS3 and REACH compliance certifications, satisfying regulatory requirements for new designs and legacy system support.

Electrical Specifications: The substitute provides equivalent voltage rating (300 V UL) with enhanced current capacity (15A UL vs. unspecified original), representing a performance improvement without introducing incompatibility.

Thermal Performance: The substitute extends the operating temperature range to -40°C ~ 115°C, providing broader environmental tolerance than the original -30°C ~ 105°C specification.

Mechanical Compatibility: Identical pitch (5.00mm), position count (23), and header configuration ensure direct mechanical and electrical interface compatibility in existing PCB layouts and connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can OP2300000000G be used as a direct replacement for OSTEP230000 in existing designs?

A: Yes. Both parts share identical pitch (5.00mm), position count (23), header configuration (male pins, unshrouded), and voltage rating (300V UL). The substitute is mechanically and electrically compatible with existing PCB layouts and mating connectors designed for the original part.

Q: What are the key differences between these parts?

A: The primary differences are: (1) Product status—OSTEP230000 is obsolete while OP2300000000G is active; (2) Mounting method—original uses solder termination, substitute uses through-hole; (3) Current rating—substitute specifies 15A UL vs. unspecified original; (4) Operating temperature range—substitute extends to -40°C ~ 115°C vs. -30°C ~ 105°C original; (5) Housing material—substitute specifies thermoplastic with UL94 V-0 flammability rating.

Q: Are there any compliance concerns with substitution?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory and environmental compliance requirements are satisfied by the substitute part.

Q: What is the contact tail length difference, and does it affect compatibility?

A: The original part specifies 0.157" (4.00mm) contact tail length while the substitute specifies 0.138" (3.50mm). This dimensional difference may require PCB layout verification for applications with tight solder joint clearance specifications. Insulation height also differs (0.157" vs. 0.079"), which should be confirmed against mating connector specifications.

Q: Is the substitute part available in the same packaging as the original?

A: The substitute is supplied in bulk packaging. Original packaging information for OSTEP230000 was not specified in the source data. Confirm packaging requirements with your procurement department.

Q: What is the base product number for the substitute?

A: The base product number for OP2300000000G is OP23, indicating the 23-position configuration within the Amphenol Anytek OP series terminal block family.
