Amphenol ICC 70232-148 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70232-148 is a 24-position PCB header connector with male pins configured for through-hole mounting. This connector belongs to the Metral® series and is designed for backplane applications requiring press-fit termination. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. Active alternatives with compatible electrical and mechanical specifications are available to maintain design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 70232-148 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: 24 positions at 0.079" (2.00mm) pitch
Physical Configuration: 4-row arrangement with through-hole mounting
Termination Method: Press-fit contact termination
Electrical Performance: 1A current rating and gold contact finish
Environmental Compliance: UL94 V-0 flammability rating and -55°C ~ 125°C operating range
Moisture Sensitivity: MSL 1 classification

Substitute parts must maintain these parameters to ensure mechanical and electrical compatibility within the original application context.

Engineering Selection Recommendations

70232-148LF is the direct successor to the 70232-148 within the Amphenol ICC Metral® series. Both parts share identical electrical and mechanical specifications. The primary distinction is product status: 70232-148LF is active and RoHS Compliant, whereas the original 70232-148 is obsolete and RoHS non-compliant. For new designs and ongoing production requiring compliance with current environmental regulations, 70232-148LF is the preferred selection.

5536514-1 from TE Connectivity AMP Connectors (Z-PACK series) meets all critical mechanical and environmental parameters: 24 positions, 0.079" pitch, 4-row configuration, through-hole mounting, press-fit termination, gold contacts, UL94 V-0 rating, and -55°C ~ 125°C operating range. This part is active and ROHS3 Compliant. The connector style designation as Futurebus and the specified 30V voltage rating represent design variations within the same form factor. Selection of this part requires confirmation that the Futurebus connector style and voltage specification are compatible with the application requirements.

Frequently Asked Questions (FAQ)

Q: Can 70232-148LF be used as a direct replacement for 70232-148?

A: Yes. Both parts maintain identical position count (24), pitch (0.079"), row configuration (4), mounting type (through-hole), termination method (press-fit), contact finish (gold at 30.0µin), current rating (1A), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0). The primary difference is product status and RoHS compliance. 70232-148LF is the active equivalent.

Q: What are the key differences between 70232-148LF and 5536514-1?

A: Both parts share the same position count, pitch, row configuration, mounting type, termination method, operating temperature range, and flammability rating. The 5536514-1 is manufactured by TE Connectivity rather than Amphenol ICC and carries a Futurebus connector style designation with a 30V voltage rating. The 70232-148LF maintains the Metral® series designation. Mechanical compatibility is established; however, connector style and voltage specifications should be confirmed against application requirements.

Q: Are there packaging differences between these substitutes?

A: Yes. The 70232-148LF is supplied in Tray packaging, while 5536514-1 is supplied in Tube packaging. Packaging selection may affect handling, storage, and integration into assembly processes but does not impact electrical or mechanical performance.

Q: What is the significance of RoHS compliance status?

A: The original 70232-148 is RoHS non-compliant. Both 70232-148LF (RoHS Compliant) and 5536514-1 (ROHS3 Compliant) meet current environmental regulations. For applications subject to RoHS requirements or future regulatory compliance mandates, selection of a compliant substitute is necessary.

Q: Can the 5536514-1 be used in applications originally designed for the 70232-148?

A: Mechanical and electrical compatibility is established through matching position count, pitch, row configuration, mounting type, termination method, contact finish, current rating, operating temperature range, and flammability rating. The Futurebus connector style and 30V voltage rating of the 5536514-1 represent design variations. Compatibility depends on whether these specifications align with the original application design parameters.
