Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST60-18P(50) is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle
• Number of positions: 18
• Pitch - mating: 0.020" (0.50mm)
• Mounting type: Board edge, surface mount, right angle
• Contact finish - mating: Gold
• Current rating: 0.5A
• Voltage rating: 100VAC
• Operating temperature range: -30°C ~ 80°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Series: ST

The ST60-18P(30) meets all these criteria and is identified as the manufacturer-recommended substitute. The primary distinction between these parts is the contact finish thickness specification on the mating surface and post finish details, which do not affect functional compatibility for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The ST60-18P(30) is the appropriate substitute for the obsolete ST60-18P(50). Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and operating ratings.

The ST60-18P(30) offers the advantage of active product status, ensuring continued availability and supply chain support. This part is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The ST60-18P(30) is available in Tape & Reel packaging, supporting automated assembly processes.

Selection of the ST60-18P(30) eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs utilizing the ST60-18P(50).

Frequently Asked Questions (FAQ)

Q: Are the ST60-18P(50) and ST60-18P(30) physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting configurations, and contact arrangements. The 18-position receptacle design, 0.020" (0.50mm) pitch, board edge surface mount right-angle orientation, and insulation height are identical across both parts.

Q: What is the difference between ST60-18P(50) and ST60-18P(30)?

A: The primary difference is contact finish thickness specification. The ST60-18P(50) specifies 50.0µin contact finish thickness on the mating surface, while the ST60-18P(30) specifies 30.0µin (0.76µm). Additionally, the ST60-18P(30) includes gold post finish specification marked as flash. The ST60-18P(50) is obsolete; the ST60-18P(30) is active.

Q: Can I use ST60-18P(30) in place of ST60-18P(50) in existing designs?

A: Yes. The ST60-18P(30) is the manufacturer-recommended substitute. All electrical ratings, mechanical specifications, and operating parameters are equivalent. The connector will function identically in applications designed for the ST60-18P(50).

Q: What packaging options are available for the substitute part?

A: The ST60-18P(30) is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly operations.

Q: Are there compliance differences between these parts?

A: The ST60-18P(30) is RoHS3 compliant and REACH unaffected. Compliance status for the obsolete ST60-18P(50) is not specified in available documentation. Both parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.
