Amphenol ICC 70236-301 Backplane Connector – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70236-301 is an 8-position header connector with male blades designed for through-hole PCB mounting in power distribution applications. This connector features press-fit termination, gold-plated contacts rated for 3A continuous current, and operates across the industrial temperature range of -55°C to 125°C. The part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 70236-301 is determined by the following critical parameters:

Connector Type & Style: Header with male blades for power distribution
Position Count & Pitch: 8 positions at 0.236" (6.00mm) spacing
Physical Configuration: 4-row arrangement, through-hole mounting
Electrical Performance: 3A current rating, gold contact finish
Environmental Compliance: UL94 V-0 flammability rating, -55°C to 125°C operating range
Termination Method: Press-fit contact technology

Substitute parts must maintain compatibility across these parameters. The 70236-301LF represents a direct manufacturer equivalent with identical electrical and mechanical specifications but with active product status and improved compliance. The TE Connectivity 536603-1 functions as a cross-manufacturer alternative within the same connector category, maintaining core electrical and mechanical compatibility while offering different connector styling and compliance attributes.

Engineering Selection Recommendations

70236-301LF (Direct Equivalent): This part is the primary substitute for the obsolete 70236-301. It maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection of this part eliminates obsolescence risk and aligns with modern regulatory requirements. The packaging format (Tube) differs from the original but does not affect functional compatibility.

536603-1 (Cross-Manufacturer Alternative): This TE Connectivity part provides functional equivalence with matching position count, pitch, mounting type, and termination method. It maintains the required UL94 V-0 flammability rating and operating temperature range. The contact finish differs (Flash vs. 30.0µin thickness) and RoHS compliance status differs. This option is suitable when Amphenol ICC parts are unavailable, provided design validation confirms compatibility with the alternative connector styling and contact specifications.

Frequently Asked Questions (FAQ)

Q: Can 70236-301LF be used as a direct replacement for 70236-301?

A: Yes. The 70236-301LF maintains identical electrical and mechanical specifications including 8 positions, 0.236" pitch, 4-row configuration, 3A current rating, gold contact finish, and -55°C to 125°C operating range. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (Compliant vs. Non-compliant).

Q: What are the key differences between 70236-301LF and 536603-1?

A: Both parts share the same position count, pitch, row configuration, mounting type, and termination method. Differences include manufacturer (Amphenol ICC vs. TE Connectivity), connector styling (Blade Power vs. Futurebus), contact finish specification (30.0µin vs. Flash), and RoHS compliance status. The 536603-1 includes a 30V voltage rating specification not provided for the Amphenol parts.

Q: Are there packaging considerations when substituting these parts?

A: The 70236-301 packaging is not specified in available data. The 70236-301LF is supplied in Tube packaging. The 536603-1 packaging is not specified. Verify packaging requirements for your procurement and assembly processes before finalizing part selection.

Q: Does the contact finish difference between 70236-301LF and 536603-1 affect compatibility?

A: Both parts use gold plating. The 70236-301LF specifies 30.0µin (0.76µm) thickness, while 536603-1 specifies Flash plating. Both meet the electrical and environmental requirements for the application. Contact finish thickness may affect long-term contact resistance characteristics in high-cycle mating applications; verify requirements for your specific use case.

Q: What is the significance of RoHS compliance for these parts?

A: The 70236-301 is RoHS non-compliant, while 70236-301LF is RoHS Compliant. If your application or market requires RoHS compliance, 70236-301LF is the appropriate selection. The 536603-1 is RoHS non-compliant.
