Amphenol ICC 70233-126 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70233-126 is a 48-position backplane connector header with male pins designed for through-hole PCB mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The part operates within a temperature range of -55°C to 125°C and is rated for 1A current per contact with gold plating at 30.0µin thickness.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 70233-126 is determined by the following critical parameters: 48-position count, 0.079" (2.00mm) pitch, 4-row configuration, through-hole mounting, male pin connector type, gold contact finish, 1A current rating, and -55°C to 125°C operating temperature range.

Two substitute parts meet these core electrical and mechanical requirements:

70233-126LF (Amphenol ICC): Direct manufacturer substitute with identical electrical specifications. Differs in product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). Packaging is tube format.

5536513-2 (TE Connectivity AMP Connectors): Cross-manufacturer substitute from the Z-PACK series. Maintains 48-position, 2.00mm pitch, 4-row through-hole configuration with male pins and gold contact finish. Differs in connector style (Futurebus), termination method (solder vs. press-fit), and includes board guide feature. Voltage rating specified at 30V. RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

70233-126LF is the primary substitute for the obsolete 70233-126. Both parts are manufactured by Amphenol ICC within the Metral® series and share identical electrical and mechanical specifications. The 70233-126LF is active in production and RoHS compliant, addressing the obsolescence and regulatory compliance limitations of the original part. This substitute requires no design modification and provides direct form-fit-function replacement.

5536513-2 serves as a cross-manufacturer alternative from TE Connectivity. While maintaining the critical 48-position, 2.00mm pitch, and 4-row through-hole configuration, this part operates under different design parameters: solder termination instead of press-fit, Futurebus connector style, and inclusion of a board guide feature. The 5536513-2 is ROHS3 compliant and specifies a 30V voltage rating. Selection of this substitute requires PCB design evaluation to accommodate solder termination and board guide integration.

Frequently Asked Questions (FAQ)

Q: Can 70233-126LF be used as a direct replacement for 70233-126?

A: Yes. The 70233-126LF maintains identical position count (48), pitch (2.00mm), row configuration (4), connector type (header male pins), mounting method (through-hole), termination (press-fit), contact finish (gold at 30.0µin), current rating (1A), and operating temperature range (-55°C to 125°C). The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

Q: What are the key differences between 70233-126LF and 5536513-2?

A: Both maintain 48 positions, 2.00mm pitch, 4-row configuration, and through-hole male pin headers. The 5536513-2 differs in termination method (solder vs. press-fit), connector style (Futurebus), and includes a board guide feature. The 5536513-2 specifies 30V voltage rating and ROHS3 compliance. Selection depends on PCB design compatibility with solder termination and board guide requirements.

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

A: No. The 5536513-2 uses solder termination, whereas the original 70233-126 and direct substitute 70233-126LF use press-fit termination. PCB design modifications are required to accommodate solder termination if selecting the 5536513-2.

Q: What compliance certifications apply to each substitute?

A: The 70233-126LF is RoHS compliant. The 5536513-2 is ROHS3 compliant. Both parts carry UL94 V-0 material flammability rating and operate within -55°C to 125°C temperature range. The original 70233-126 is RoHS non-compliant.

Q: Are there packaging differences between substitutes?

A: The 70233-126LF is supplied in tube packaging. Packaging information for the 5536513-2 is specified as tube format. The original 70233-126 packaging is not specified in available data.
