Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTV7027151 is determined by the following critical parameters:

• Number of Positions: Must be 2
• Type: Must be Header, Female Sockets
• Header Orientation: Must be 90°, Right Angle
• Mounting Type: Must be Solder
• Voltage Rating: Must be 300V or higher
• Operating Temperature Range: Must encompass -30°C ~ 105°C
• Housing Material: Must be Thermoplastic
• Contact Tail Length: Must be 0.138" (3.50mm)
• Insulation Height: Must be 0.138" (3.50mm)
• Material Flammability Rating: Must be UL94 V-0

The OSTV7025151 qualifies as a substitute based on these parameters. The primary difference is the pitch specification: 0.200" (5.08mm) versus the original 0.197" (5.00mm). This represents a minor pitch variation within acceptable tolerance for terminal block applications in this category.

Parameter Comparison

Engineering Selection Recommendations

The OSTV7025151 is the manufacturer-recommended substitute for the obsolete OSTV7027151. Both components maintain identical electrical and mechanical specifications with the exception of pitch tolerance. The substitute part carries active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between OSTV7027151 and OSTV7025151?

A: The pitch specification differs: OSTV7027151 uses 0.197" (5.00mm) pitch, while OSTV7025151 uses 0.200" (5.08mm) pitch. All other electrical and mechanical parameters remain identical.

Q: Can OSTV7025151 be used as a direct replacement for OSTV7027151?

A: The OSTV7025151 is the manufacturer-recommended substitute. The pitch variation must be evaluated within the context of your specific PCB layout and connector design to ensure mechanical compatibility.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 flammability ratings, and maintain identical voltage and temperature specifications.

Q: Why is OSTV7027151 listed as obsolete?

A: The OSTV7027151 has been discontinued by the manufacturer. The OSTV7025151 represents the active product line continuation within the OSTV7 series.

Q: What are the critical parameters for substitution eligibility?

A: Substitutes must maintain 2-position configuration, 90° right-angle orientation, solder mounting, 300V voltage rating, -30°C to 105°C operating temperature range, thermoplastic housing, UL94 V-0 flammability rating, and identical contact tail and insulation height dimensions.
