Amphenol ICC 70236-144 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70236-144 is an 8-position connector header with male blades designed for through-hole PCB mounting in backplane applications. This part operates within the Metral® series and features press-fit termination with gold-plated contacts rated for 3A continuous current across an operating temperature range of -55°C to 125°C.

The 70236-144 is classified as obsolete. 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 use.

Substitute Part Grouping Explanation

Substitute parts for the 70236-144 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for functional substitution:

• Connector type: Header, Male Blades
• Number of positions: 8
• Pitch: 0.236" (6.00mm)
• Number of rows: 4
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact layout: 8 Power
• Material flammability rating: UL94 V-0
• Operating temperature range: -55°C to 125°C

The 70236-144LF is a direct manufacturer equivalent from Amphenol ICC, differing only in RoHS compliance status and packaging format. The TE Connectivity 536603-1 shares the same mechanical footprint, pitch, position count, and mounting characteristics but operates under a different connector style designation (Futurebus versus Blade Power).

Parameter Comparison

Engineering Selection Recommendations

The 70236-144LF is the primary substitute for the obsolete 70236-144. Both parts are manufactured by Amphenol ICC within the Metral® series and share identical electrical and mechanical specifications. The 70236-144LF is currently in active production status with RoHS compliance, making it the preferred choice for new designs and ongoing supply requirements.

The TE Connectivity 536603-1 provides an alternative from a different manufacturer. It maintains mechanical and thermal compatibility but operates under the Futurebus connector style classification. This part is also in active production status. Selection between the Amphenol and TE Connectivity options depends on existing design qualification, connector interface requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 70236-144LF be used as a direct replacement for the 70236-144?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting method, termination style, contact finish, current rating, flammability rating, and operating temperature range. The primary difference is RoHS compliance status and packaging format.

Q: What is the significance of the "LF" designation in the 70236-144LF part number?

A: The "LF" suffix indicates lead-free construction and RoHS compliance. This part meets RoHS Directive requirements, whereas the original 70236-144 does not.

Q: Is the TE Connectivity 536603-1 mechanically compatible with the 70236-144?

A: Yes, regarding physical footprint and PCB mounting. Both connectors feature 8 positions, 0.236" (6.00mm) pitch, 4-row configuration, through-hole mounting, and press-fit termination. However, the connector style differs (Futurebus versus Blade Power), which may affect mating interface compatibility depending on the application.

Q: What packaging formats are available for these substitute parts?

A: The 70236-144 and 536603-1 do not specify packaging format in the provided data. The 70236-144LF is supplied in tube packaging.

Q: Are there compliance or certification differences between these parts?

A: All three parts meet UL94 V-0 flammability requirements and operate across -55°C to 125°C. The 70236-144LF is RoHS Compliant, while the 70236-144 and 536603-1 are RoHS non-compliant. The 70236-144LF is REACH Affected; the 70236-144 is REACH Unaffected; the 536603-1 is REACH Affected.
