Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70233-148LF is determined by strict alignment of the following critical parameters:

• Position Count: 48 positions (exact match required)
• Pitch Specification: 0.079" (2.00mm) (exact match required)
• Row Configuration: 4 rows (exact match required)
• Mounting Technology: Through Hole (exact match required)
• Connector Type: Header, Male Pins (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Material Flammability Rating: UL94 V-0 (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: RoHS Compliant or equivalent (minimum requirement)

The substitute part 5536513-2 (TE Connectivity AMP Connectors, Z-PACK series) meets all critical electrical and mechanical parameters for direct substitution in PCB backplane applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 70233-148LF and 5536513-2 are active production components with equivalent electrical and mechanical specifications for 48-position backplane connector applications. Selection between these parts should be based on the following engineering considerations:

70233-148LF (Amphenol ICC Metral® Series): Press-fit termination technology provides automated assembly compatibility and consistent contact retention without solder reflow processes. RoHS Compliant status meets standard environmental regulations.

5536513-2 (TE Connectivity Z-PACK Series): Solder termination requires wave or reflow soldering processes and offers ROHS3 Compliant certification. The specified 30V voltage rating provides explicit electrical parameter documentation. Board guide feature supports mechanical alignment during assembly.

Both parts satisfy UL94 V-0 flammability requirements, operate across the -55°C to 125°C temperature range, and maintain MSL 1 (Unlimited) moisture sensitivity classification. Component selection should align with existing assembly processes, PCB design requirements, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 5536513-2 directly replace 70233-148LF in existing designs?

A: Yes, for applications where the connector footprint, pitch (2.00mm), position count (48), and row configuration (4) are fixed. The primary difference is termination method: 70233-148LF uses press-fit technology while 5536513-2 requires solder attachment. PCB design and assembly process compatibility must be verified.

Q: What is the significance of the termination difference between these parts?

A: Press-fit termination (70233-148LF) eliminates solder reflow and provides mechanical retention without thermal stress. Solder termination (5536513-2) requires wave or reflow soldering but may offer cost advantages in high-volume production. Both methods achieve equivalent electrical performance when properly executed.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -55°C to 125°C, meeting equivalent thermal specifications for industrial and computing applications.

Q: What does the board guide feature on 5536513-2 provide?

A: The board guide is a mechanical alignment feature that assists in proper connector positioning during PCB assembly, reducing misalignment risk during insertion.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The 70233-148LF is RoHS Compliant, and the 5536513-2 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: Is the 30V voltage rating on 5536513-2 a limiting factor?

A: The 70233-148LF does not specify a voltage rating in the provided data. The 5536513-2 explicitly rates 30V. Application voltage requirements must be verified against both parts' electrical specifications before substitution.
