OSTEP030000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTEP030000 is a 3-position terminal block header manufactured by On-Shore Technology, 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 functionally equivalent alternatives essential for ongoing design support and procurement continuity. The substitute part OP0300000000G from Amphenol Anytek provides equivalent electrical and mechanical functionality while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of OSTEP030000 with OP0300000000G is based on the following critical parameters that must remain constant:

• Electrical Compatibility: Both parts maintain 300 V voltage rating and tin contact mating finish
• Mechanical Compatibility: Identical 3-position configuration, 0.197" (5.00mm) pitch, and vertical orientation
• Connector Type: Both are male pin headers in unshrouded configuration
• Environmental Compliance: Both meet ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity requirements

The primary difference is mounting method: OSTEP030000 uses solder termination, while OP0300000000G uses through-hole mounting with solder termination. Both are solder-based assembly methods suitable for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

OP0300000000G is the designated manufacturer-recommended substitute for OSTEP030000. Selection of this alternative is justified by:

• Product Lifecycle: OSTEP030000 is obsolete; OP0300000000G maintains active status with ongoing manufacturing support
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements with identical MSL ratings
• Electrical Specifications: Voltage and contact finish specifications are equivalent; OP0300000000G provides additional current rating specifications (12 A IEC, 15 A UL)
• Environmental Range: OP0300000000G extends the operating temperature range to -40°C ~ 115°C, providing broader thermal compatibility
• Mechanical Fit: Identical pitch, position count, and orientation ensure direct functional replacement in PCB designs

Physical dimensions differ slightly in contact tail length and insulation height; PCB footprint verification is necessary during design transition.

Frequently Asked Questions (FAQ)

Q: Can OP0300000000G be used as a direct replacement for OSTEP030000?

A: Yes. Both parts share identical electrical ratings (300 V), connector configuration (3-position, 0.197" pitch, vertical, male unshrouded), and compliance certifications (ROHS3, MSL 1). The through-hole mounting method of OP0300000000G is compatible with standard PCB assembly processes.

Q: What are the physical differences between these parts?

A: Contact tail length differs (0.157" vs. 0.138") and insulation height differs (0.157" vs. 0.079"). These dimensional variations require PCB footprint verification to ensure proper fit and solder joint formation.

Q: Are there any electrical performance differences?

A: OP0300000000G provides explicit current ratings (12 A IEC, 15 A UL) and extends the operating temperature range to -40°C ~ 115°C compared to OSTEP030000's -30°C ~ 105°C. Both maintain 300 V voltage rating and tin contact finish.

Q: What is the packaging difference?

A: OSTEP030000 packaging is not specified in available data. OP0300000000G is supplied in bulk packaging, standard for through-hole terminal block headers.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTEP030000 and OP0300000000G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard PCB assembly and storage conditions.
