Key Parameters

Substitute Part Grouping Explanation

Substitution for the ST80X-24S(50) is based on the following critical parameters that must remain constant:

• Connector Type & Series: Plug, Cradle configuration within the ST series
• Position Count & Pitch: 24 positions at 0.039" (1.00mm) mating pitch
• Mounting Technology: Surface mount with solder termination
• Electrical Ratings: 0.5A current and 100V voltage ratings
• Environmental Specifications: Operating temperature range -30°C ~ 80°C and UL94 V-0 flammability rating
• Mechanical Features: Board guide, mounting flange, and shielded design
• Contact Material & Finish: Copper alloy with gold-plated mating contacts

The ST80X-24S(30) qualifies as a direct substitute based on identical compliance with all these parameters. The primary distinction is packaging format and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The ST80X-24S(30) is the direct functional equivalent for the obsolete ST80X-24S(50). Selection of the substitute part is justified by:

• Identical Electrical Performance: Both parts maintain 0.5A current rating and 100V voltage rating with matching operating temperature specifications
• Mechanical Compatibility: Pin count, pitch, mounting type, and physical dimensions are identical, ensuring PCB layout compatibility without redesign
• Regulatory Compliance: Both parts meet UL94 V-0 flammability requirements
• Active Product Status: The ST80X-24S(30) is currently in active production, ensuring long-term availability and supply chain stability
• Enhanced Compliance: The substitute part includes RoHS compliance certification, providing additional environmental regulatory alignment

The transition from bulk packaging to Tape & Reel format in the ST80X-24S(30) represents a standard industry practice for active production components and does not affect functional or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ST80X-24S(30) be used as a direct replacement for the ST80X-24S(50) without PCB modifications?

A: Yes. Both parts share identical pin counts (24), mating pitch (1.00mm), mounting type (surface mount), and physical dimensions. No PCB layout changes are required.

Q: What is the difference between the ST80X-24S(50) and ST80X-24S(30)?

A: The primary differences are product status and packaging format. The ST80X-24S(50) is obsolete with unspecified packaging, while the ST80X-24S(30) is an active production part supplied in Tape & Reel format. The ST80X-24S(30) also includes RoHS compliance certification. All electrical and mechanical specifications are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical current ratings (0.5A), voltage ratings (100V), operating temperature ranges (-30°C ~ 80°C), and contact materials (copper alloy with gold plating).

Q: Why is the ST80X-24S(50) marked as obsolete?

A: The ST80X-24S(50) has been superseded by the ST80X-24S(30) in the manufacturer's active product line. The ST80X-24S(30) represents the current production equivalent with enhanced compliance features.

Q: Does Tape & Reel packaging affect compatibility?

A: No. Tape & Reel is a packaging and delivery format for automated assembly processes. It does not affect the connector's electrical or mechanical performance when soldered to the PCB.

Q: Is the RoHS compliance difference significant?

A: The RoHS compliance of the ST80X-24S(30) provides additional regulatory alignment for applications subject to environmental directives. Both parts are functionally equivalent; RoHS compliance is an enhancement in the substitute part.
