ST60X-18S Equivalent & Substitute Parts

Part Overview

The ST60X-18S is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 18 positions at 0.5mm pitch. This connector is classified as obsolete, which necessitates identification of active equivalent parts to ensure design continuity and procurement availability. The part functions as a board-to-cable/wire interface with solder termination and latch holder fastening, suitable for applications requiring compact, high-density interconnection.

Key Parameters

Substitute Part Grouping Explanation

The ST60X-18S(30) is identified as the manufacturer-recommended substitute. Substitution validity is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Plug, Cradle; Non-Gendered)
• Electrical specifications (0.5A current rating, 100V voltage rating)
• Physical dimensions (18 positions, 0.5mm pitch, 0.116" insulation height)
• Mounting configuration (Surface Mount, Right Angle)
• Termination method (Solder with Latch Holder fastening)
• Material and environmental compliance (Polyamide PA9T insulation, UL94 V-0, -30°C ~ 80°C operating range)

The primary distinction between the main part and substitute is product status and packaging format. The ST60X-18S(30) is active production status with Tape & Reel packaging, whereas the original ST60X-18S is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The ST60X-18S(30) is the direct functional equivalent for the obsolete ST60X-18S. Selection of the substitute is based on:

• Identical electrical and mechanical specifications across all critical parameters
• Active production status ensuring long-term availability and supply chain continuity
• RoHS compliance certification of the substitute part, meeting current regulatory requirements
• Equivalent environmental ratings and material specifications
• Tape & Reel packaging format suitable for automated assembly processes

For applications currently using the ST60X-18S, transition to ST60X-18S(30) requires no design modifications. PCB footprints, mating interface specifications, and electrical performance remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can ST60X-18S(30) be used as a direct replacement for ST60X-18S?

A: Yes. Both parts share identical connector type, position count, pitch, mounting configuration, electrical ratings, and material specifications. The substitute is the manufacturer-recommended equivalent.

Q: What is the primary difference between these parts?

A: The ST60X-18S is obsolete, while ST60X-18S(30) is active production. The substitute includes RoHS compliance certification and is supplied in Tape & Reel packaging format.

Q: Are there any compatibility concerns with existing designs?

A: No. The parts are mechanically and electrically interchangeable. Existing PCB designs, mating connectors, and assembly processes require no modification.

Q: What does the "(30)" designation indicate?

A: The "(30)" suffix indicates the packaging format (Tape & Reel) and production variant. The core connector specification remains identical to the base ST60X-18S.

Q: Is RoHS compliance a functional difference?

A: RoHS compliance is a material composition and regulatory requirement, not a functional specification. Both parts meet the same electrical and mechanical performance criteria.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
