Amphenol ICC 70233-148 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70233-148 is a 48-position PCB header connector with male pins, designed for through-hole mounting in backplane applications. This connector features a 2.00mm pitch, press-fit termination, and gold-plated contacts rated for 1A current. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 70233-148 is determined by the following critical parameters that must remain consistent across equivalent parts:

• Number of positions: 48
• Pitch: 0.079" (2.00mm)
• Number of rows: 4
• Connector type: Header, Male Pins
• Mounting type: Through Hole
• Contact finish: Gold
• Operating temperature range: -55°C to 125°C
• Material flammability rating: UL94 V-0
• Current rating: 1A

Two substitute parts are identified based on these parameters:

1. 70233-148LF (Amphenol ICC) — Direct manufacturer equivalent with active product status and RoHS compliance
2. 5536513-2 (TE Connectivity AMP Connectors) — Cross-manufacturer substitute with Futurebus connector style and solder termination

Parameter Comparison

Engineering Selection Recommendations

70233-148LF is the primary substitute for the obsolete 70233-148. Both parts are manufactured by Amphenol ICC within the Metral® series and maintain identical electrical and mechanical specifications. The 70233-148LF offers the advantage of active product status and RoHS compliance, addressing regulatory requirements for new designs while preserving press-fit termination compatibility with existing PCB layouts.

5536513-2 serves as a cross-manufacturer alternative from TE Connectivity. This part maintains the same 48-position, 2.00mm pitch configuration and through-hole mounting but employs solder termination instead of press-fit. The Futurebus connector style and active product status with ROHS3 compliance make this suitable for applications where solder termination is acceptable. The absence of specified current rating and contact finish thickness requires verification against application requirements.

Selection between 70233-148LF and 5536513-2 depends on termination method compatibility: press-fit for direct replacement or solder for alternative assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 70233-148LF be used as a direct replacement for 70233-148?

A: Yes. Both parts share identical electrical and mechanical parameters including 48 positions, 2.00mm pitch, 4-row configuration, through-hole mounting, press-fit termination, gold contact finish, 1A current rating, and -55°C to 125°C operating range. The primary difference is product status and RoHS compliance.

Q: What is the key difference between 70233-148LF and 5536513-2?

A: The termination method differs. The 70233-148LF uses press-fit termination compatible with the original 70233-148 design, while 5536513-2 requires solder termination. Both maintain the same position count, pitch, and row configuration.

Q: Is 5536513-2 suitable for applications requiring press-fit assembly?

A: No. The 5536513-2 is specified for solder termination. Press-fit assembly requires either 70233-148 or 70233-148LF.

Q: What are the compliance differences between these parts?

A: The 70233-148 is RoHS non-compliant. The 70233-148LF is RoHS compliant. The 5536513-2 is ROHS3 compliant. For applications subject to RoHS regulations, 70233-148LF or 5536513-2 are required.

Q: Are all three parts available in the same packaging?

A: The 70233-148 packaging is unspecified. The 70233-148LF and 5536513-2 are both supplied in tube packaging.

Q: What is the inventory status for these parts?

A: The 70233-148 has 1052 pieces in stock (obsolete status). The 70233-148LF has 820 pieces in stock (active). The 5536513-2 has 1028 pieces in stock (active).
