Amphenol ICC 55510-030LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55510-030LF is a 30-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This connector features gold-plated mating contacts, operates across -55°C to 125°C, and is rated for 2A at 200V. The product is active and RoHS compliant with UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55510-030LF is determined by strict alignment of core electrical and mechanical parameters. The substitute part 150230-2020-RB from 3M meets the following critical criteria:

Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 30
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Surface mount
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Insulation color: Black
• Material flammability rating: UL94 V-0
• RoHS status: RoHS compliant
• Moisture sensitivity level: 1 (Unlimited)

These parameters establish mechanical and electrical compatibility for direct substitution in board-to-board surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 55510-030LF and 150230-2020-RB are active products with RoHS compliance and UL94 V-0 flammability certification, establishing baseline suitability for equivalent applications. The 55510-030LF operates to 125°C with 2A current rating at 200V. The 150230-2020-RB operates to 105°C with 1A current rating at 500VDC. Selection between these parts depends on application-specific requirements for maximum operating temperature and current capacity. Both connectors share identical mechanical pitch, row configuration, and surface mount termination, enabling direct physical interchangeability in board-to-board configurations. The 150230-2020-RB includes a board guide feature not present in the 55510-030LF.

Frequently Asked Questions (FAQ)

Q: Can the 150230-2020-RB directly replace the 55510-030LF in all applications?

A: Direct replacement is possible when application requirements do not exceed the 150230-2020-RB specifications. The substitute part operates to 105°C maximum (versus 125°C for the original) and is rated for 1A (versus 2A for the original). Applications requiring higher temperature operation or current capacity must use the 55510-030LF.

Q: What are the key mechanical compatibility factors?

A: Both connectors share 0.079" (2.00mm) pitch, 2-row configuration with 0.079" row spacing, surface mount termination, and push-pull fastening. Insulation heights differ slightly (0.177" versus 0.183"), but this variance falls within typical PCB layout tolerances for board-to-board applications.

Q: Are there differences in contact finish specifications?

A: Both connectors feature gold-plated mating contacts. The 55510-030LF specifies 1.97µin (0.050µm) gold thickness, while the 150230-2020-RB specifies 30.0µin (0.76µm). Both meet gold plating requirements for connector reliability and signal integrity.

Q: What is the significance of the board guide feature on the 150230-2020-RB?

A: The board guide on the 150230-2020-RB provides mechanical alignment assistance during mating. The 55510-030LF does not include this feature. This difference does not affect electrical compatibility but may influence mechanical assembly procedures.

Q: Are both parts suitable for industrial and medical applications?

A: Both connectors are RoHS compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity, establishing compliance for general industrial use. Application-specific certifications and environmental requirements must be evaluated independently for medical or specialized industrial deployments.
