Amphenol ICC 52057-102 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 52057-102 is a 36-position high-speed backplane connector receptacle with female sockets, designed for board edge mounting through press-fit termination. This connector features a Metral® 4000 series design with shielded construction and gold-plated contacts rated for 1A continuous current across an operating temperature range of -55°C to 105°C.

The 52057-102 is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this connector type remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 52057-102 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector type (Receptacle, Female Sockets)
• Pitch specification (0.079" / 2.00mm)
• Mounting configuration (Board Edge, Through Hole, Right Angle)
• Termination method (Press-Fit)
• Contact finish (Gold)
• Flammability rating (UL94 V-0)
• Operating temperature range capability

Substitute Classification:

The 52057-102LF is a direct equivalent manufactured by Amphenol ICC under the same base product number (52057) with identical electrical and mechanical specifications. The primary distinction is product status transition from obsolete to active, along with RoHS compliance upgrade and packaging format change to tube.

The 5223008-1 manufactured by TE Connectivity represents a functional alternative within the backplane connector category. While this part maintains core compatibility parameters including pitch, mounting type, termination method, and contact finish, it operates under a different connector style (Futurebus versus High Speed) and differs in position count (30 versus 36 positions).

Parameter Comparison

Engineering Selection Recommendations

52057-102LF (Direct Substitute):

The 52057-102LF is the primary substitute for the obsolete 52057-102. Both connectors share identical mechanical and electrical specifications, including position count, pitch, mounting configuration, and current rating. The 52057-102LF offers the advantage of active product status with current manufacturing support. Additionally, the 52057-102LF achieves RoHS compliance, addressing regulatory requirements for new designs and procurement cycles. This part is suitable for direct replacement in existing applications without design modification.

5223008-1 (Functional Alternative):

The 5223008-1 serves as a functional alternative for applications where position count reduction is acceptable. This TE Connectivity connector maintains compatibility across pitch, mounting type, termination method, and contact finish specifications. The 5223008-1 provides an extended operating temperature range to 125°C, which may benefit thermal-demanding applications. However, the reduction from 36 to 30 positions requires circuit board redesign and connector footprint modification. This alternative is applicable only when system architecture permits position count adjustment.

Frequently Asked Questions (FAQ)

Q: Can the 52057-102LF be used as a direct replacement for the 52057-102?

A: Yes. The 52057-102LF maintains identical electrical and mechanical specifications including position count (36), pitch (0.079"), mounting type (board edge, through hole, right angle), termination method (press-fit), and contact finish (gold). The primary differences are product status transition to active and RoHS compliance upgrade. No design modification is required.

Q: What is the key difference between the 52057-102 and 52057-102LF?

A: The 52057-102 is classified as obsolete with non-compliant RoHS status, while the 52057-102LF is an active product with RoHS compliance. Both connectors are manufactured by Amphenol ICC under the Metral® 4000 series with identical specifications. The 52057-102LF is packaged in tube format.

Q: Can the 5223008-1 replace the 52057-102 in existing designs?

A: The 5223008-1 is a functional alternative only for applications where position count reduction from 36 to 30 is acceptable. This connector maintains pitch, mounting type, termination method, and contact finish compatibility. Circuit board redesign and connector footprint modification are required. The 5223008-1 operates across -55°C to 125°C, extending the upper temperature limit by 20°C compared to the 52057-102.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by pitch (0.079" / 2.00mm), mounting configuration (board edge, through hole, right angle), termination method (press-fit), contact finish (gold), and flammability rating (UL94 V-0). Position count and connector style may vary depending on application requirements and circuit board design constraints.

Q: Are there packaging differences between substitute parts?

A: The 52057-102 packaging format is not specified in available documentation. The 52057-102LF and 5223008-1 are both supplied in tube packaging. Confirm packaging requirements with procurement specifications before finalizing part selection.

Q: What compliance certifications apply to these connectors?

A: The 52057-102 is RoHS non-compliant. The 52057-102LF achieves RoHS compliance. The 5223008-1 meets ROHS3 compliance standards. All three connectors carry UL94 V-0 flammability certification and are classified under ECCN EAR99 for export control purposes.
