Amphenol ICC 93235-921 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 93235-921 is a 48-position backplane connector receptacle with female sockets designed for through-hole PCB mounting. This connector is part of the Metral® series and features a 0.079" (2.00mm) pitch configuration across 4 rows. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93235-921 is determined by the following critical parameters:

• Position Count: 48 positions (exact match required)
• Pitch Specification: 0.079" (2.00mm) (exact match required)
• Row Configuration: 4 rows (exact match required)
• Connector Type: Receptacle with female sockets (exact match required)
• Mounting Method: Through-hole PCB mounting (exact match required)
• Flammability Rating: UL94 V-0 minimum (equal or better)
• Operating Temperature Range: Minimum -55°C ~ 105°C (equal or better)
• Voltage Rating: Minimum 1000V (equal or better)

The TE Connectivity AMP Connectors 5223650-2 meets all critical dimensional and functional requirements for direct substitution. While termination method differs (press-fit versus solder), the connector maintains electrical and mechanical compatibility for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5223650-2 provides dimensional and mechanical compatibility with the obsolete 93235-921 for 48-position backplane connector applications. The substitute maintains identical pitch, row configuration, and through-hole mounting characteristics.

Key considerations for selection:

• Voltage Rating Differential: The 5223650-2 is rated at 30V versus the original 1000V specification. Applications requiring the full 1000V rating cannot use this substitute without electrical redesign validation.
• Termination Method Change: The 5223650-2 uses press-fit termination instead of solder. PCB design modifications may be required to accommodate press-fit contact holes.
• Compliance Improvement: The 5223650-2 is RoHS compliant and actively manufactured, addressing obsolescence and regulatory requirements.
• Temperature Performance: The 5223650-2 extends the upper operating temperature to 125°C, providing improved thermal margin.
• Contact Finish: Gold plating on the 5223650-2 offers enhanced corrosion resistance compared to unspecified contact finish on the original.

Frequently Asked Questions (FAQ)

Q: Can the 5223650-2 directly replace the 93235-921 in existing designs?

A: Dimensional and mechanical compatibility is confirmed for 48-position, 2.00mm pitch through-hole mounting. However, the voltage rating reduction from 1000V to 30V requires circuit-level validation. Termination method differences (press-fit versus solder) necessitate PCB design review.

Q: What is the primary reason for substitution?

A: The 93235-921 is obsolete and no longer manufactured. The 5223650-2 is an active product from a major connector manufacturer, ensuring long-term availability and supply chain continuity.

Q: Are there packaging differences between these connectors?

A: The 93235-921 packaging is not specified in available documentation. The 5223650-2 is supplied in tube packaging. Verify packaging requirements for your assembly process.

Q: Does the RoHS compliance difference affect substitution?

A: The 5223650-2 is RoHS compliant while the 93235-921 is non-compliant. For applications subject to RoHS regulations or customer requirements, the 5223650-2 meets modern environmental standards.

Q: What is the impact of the termination method change?

A: The original uses solder termination; the substitute uses press-fit. Press-fit requires different PCB hole sizing and assembly procedures. Consult connector datasheets for specific hole diameter and depth specifications.

Q: Is the extended temperature range of the 5223650-2 a benefit?

A: The 5223650-2 operates to 125°C versus 105°C for the original. This provides additional thermal margin for applications approaching the upper temperature limit.
