Amphenol ICC 70231-301 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70231-301 is an 8-position receptacle connector with female blade sockets, designed for board edge mounting in through-hole applications with right-angle orientation. This connector is part of the Metral® series and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 70231-301 is determined by the following critical parameters that must align for functional compatibility:

Primary Substitution Criteria:

• Connector type: Receptacle with female blade sockets
• Number of positions: 8
• Number of rows: 4
• Mounting configuration: Board edge, through-hole, right-angle orientation
• Termination method: Solder
• Contact layout: 8 power positions
• Material flammability rating: UL94 V-0

Identified Substitute Parts:

1. 70231-301LF (Amphenol ICC) — Direct manufacturer equivalent with identical electrical and mechanical specifications. Primary difference is active product status and RoHS compliance.

2. 5536607-1 (TE Connectivity AMP Connectors) — Manufacturer-recommended alternative from the Z-PACK series. Meets core substitution criteria with equivalent connector type, position count, row configuration, and mounting method. Operates across an extended temperature range (-55°C to 125°C) and includes RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

70231-301LF (Direct Equivalent): This part is the primary substitute for the 70231-301. It maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection of this part is appropriate for applications requiring direct compatibility with existing designs and where the original specifications remain valid.

5536607-1 (Alternative Substitute): This TE Connectivity part meets all core substitution criteria for connector type, position count, row configuration, and mounting method. It provides extended operating temperature capability (-55°C to 125°C) and RoHS3 compliance. However, the voltage rating of 30V is significantly lower than the 1000V rating of the original part. This alternative is suitable only for applications where the lower voltage rating is acceptable and where the extended temperature range provides operational benefit.

Frequently Asked Questions (FAQ)

Q: Can 70231-301LF be used as a direct replacement for 70231-301?

A: Yes. The 70231-301LF is a direct equivalent with identical connector type, position count, row configuration, mounting method, termination, contact layout, and operating temperature range. The primary differences are active product status and RoHS compliance, making it suitable for direct substitution.

Q: What are the key differences between 70231-301 and 5536607-1?

A: Both connectors share the same core mechanical and electrical architecture: 8-position receptacle with female blade sockets, 4-row configuration, board edge through-hole right-angle mounting, and solder termination. The 5536607-1 offers an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and RoHS3 compliance. The critical difference is the voltage rating: 5536607-1 is rated for 30V, while 70231-301 is rated for 1000V. This makes 5536607-1 unsuitable for high-voltage applications.

Q: Is the 5536607-1 compatible with existing 70231-301 designs?

A: Mechanical and electrical compatibility exists for the connector interface itself. However, the significantly lower voltage rating (30V versus 1000V) restricts its use to applications operating within the 30V specification. Verification of application voltage requirements is necessary before selection.

Q: What is the significance of the RoHS compliance difference?

A: The 70231-301 is RoHS non-compliant, while 70231-301LF is RoHS compliant and 5536607-1 is ROHS3 compliant. For new designs or applications subject to RoHS regulations, the compliant alternatives (70231-301LF or 5536607-1) are required. For legacy system maintenance where RoHS compliance is not mandated, the original part remains functionally valid.

Q: Are there packaging differences between these parts?

A: Yes. The 70231-301 packaging is not specified. The 70231-301LF is supplied in bulk packaging, while 5536607-1 is supplied in tube packaging. Packaging selection may affect procurement logistics and handling procedures.
