Amphenol ICC 88947-102 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 88947-102 is a 96-position receptacle backplane connector featuring female sockets with board edge, through-hole mounting in a right-angle configuration. This connector is part of the Metral® B series and is currently classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 88947-102 is determined by the following critical parameters:

• Number of Positions: 96
• Pitch: 0.079" (2.00mm)
• Number of Rows: 4
• Connector Type: Receptacle, Female Sockets
• Mounting Type: Board Edge, Through Hole, Right Angle
• Features: Board Guide, Spacer
• Material Flammability Rating: UL94 V-0
• Color: Natural

The substitute parts identified maintain these core electrical and mechanical parameters. Variations in termination method (Press-Fit vs. Solder), voltage rating, operating temperature range, and RoHS compliance status are secondary considerations that do not preclude substitution but require design validation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 88947-102LF

The 88947-102LF is the direct equivalent of the 88947-102, manufactured by Amphenol ICC (FCI) in the same Metral® B series. It maintains identical electrical and mechanical specifications, including 1000V voltage rating, 1A current rating, and -55°C to 105°C operating temperature range. The 88947-102LF is currently in active product status with 1677 units in stock, compared to the obsolete 88947-102. The primary distinction is RoHS compliance: the 88947-102LF is RoHS Compliant, whereas the original is RoHS non-compliant. This substitution is direct and requires no design modification.

Secondary Substitutes: 536507-3 and 536511-3

The TE Connectivity AMP Connectors 536507-3 and 536511-3 (Z-PACK series) maintain the same 96-position, 2.00mm pitch, 4-row configuration and board edge, through-hole, right-angle mounting. Both are Futurebus-style connectors with UL94 V-0 flammability rating. However, these parts differ in critical electrical parameters: voltage rating is 30V (versus 1000V for the 88947-102), and current rating is not specified. Operating temperature range extends to 125°C. The 536507-3 uses solder termination, while the 536511-3 uses press-fit termination. Both are obsolete. These substitutes are suitable only for applications where the lower voltage rating (30V) is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 88947-102LF directly replace the 88947-102 without PCB redesign?

A: Yes. The 88947-102LF is mechanically and electrically identical to the 88947-102. Both use press-fit termination, identical pitch, row configuration, and mounting style. No PCB layout changes are required.

Q: What is the significance of RoHS compliance in the 88947-102LF?

A: The 88947-102LF is RoHS Compliant, meaning it meets Restriction of Hazardous Substances regulations. The original 88947-102 is RoHS non-compliant. For new designs or systems subject to RoHS requirements, the 88947-102LF is the appropriate choice.

Q: Are the TE Connectivity 536507-3 and 536511-3 suitable replacements?

A: These parts share the same physical footprint and connector topology but have significantly lower voltage ratings (30V versus 1000V). They are suitable only for applications operating at 30V or below. The 536507-3 uses solder termination, requiring different assembly processes than the press-fit 88947-102.

Q: What is the difference between 536507-3 and 536511-3?

A: Both are 96-position Futurebus connectors with identical electrical and mechanical specifications. The primary difference is termination method: 536507-3 uses solder termination, while 536511-3 uses press-fit termination. Selection depends on assembly process compatibility.

Q: Why do the TE Connectivity parts have a higher operating temperature range?

A: The 536507-3 and 536511-3 are rated to -55°C to 125°C, compared to -55°C to 105°C for the Amphenol parts. This extended range is a material property of the Z-PACK series design and does not affect substitution eligibility for standard operating conditions.

Q: Is packaging a consideration for substitution?

A: The 88947-102LF is supplied in tube packaging, while the original 88947-102 packaging is not specified. Verify packaging requirements with your procurement process, as this may affect handling and storage procedures but does not impact electrical or mechanical compatibility.
