Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 223970-1 are identified based on strict electrical and mechanical parameter alignment within the backplane connector category. The substitution logic is based on the following critical parameters:

Primary Substitution Criteria:

• Connector type: Header, Male Blades
• Connector style: Blade Power
• Number of positions: 3
• Mounting configuration: Board Edge, Through Hole, Right Angle
• Termination method: Press-Fit
• Contact layout: 3 Power
• Series compatibility: UPM (Universal Power Modules)
• Connector usage: Backplane
• Board guide feature presence

Substitute Parts Identified:

1. 5223970-1 (Direct Manufacturer Equivalent) – Active product status with enhanced specifications
2. 5223963-1 (Similar Manufacturer Alternative) – Active product status with alternative contact finish specification

Both substitute parts maintain identical mechanical and electrical interface requirements, ensuring functional compatibility with applications designed for the 223970-1.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5223970-1

The 5223970-1 is the direct manufacturer equivalent and represents the primary substitute for the obsolete 223970-1. This part maintains identical mechanical and electrical interface specifications while offering active product status. The 5223970-1 provides enhanced compliance documentation with RoHS Compliant certification and specified operating temperature range (-55°C ~ 125°C) and voltage rating (250V). The contact finish is specified as Gold with defined thickness (50.0µin / 1.27µm), providing improved traceability for quality assurance applications.

Secondary Recommendation: 5223963-1

The 5223963-1 serves as an alternative substitute with equivalent mechanical and electrical compatibility. This part is classified as ROHS3 Compliant and maintains the same operating temperature range (-55°C ~ 125°C) and voltage rating (250V) as the primary recommendation. The contact finish specification allows for Gold or Gold-Palladium, matching the original 223970-1 specification. The 5223963-1 is supplied in Tube packaging and offers higher inventory availability (3020 pieces in stock).

Compliance Considerations:

Both substitute parts address the RoHS non-compliance status of the original 223970-1. Selection between 5223970-1 and 5223963-1 should be based on specific application requirements regarding contact finish specification, packaging format, and inventory lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5223970-1 be used as a direct replacement for the 223970-1?

A: Yes. The 5223970-1 maintains identical connector type, style, position count, mounting configuration, and termination method. The mechanical and electrical interfaces are fully compatible with applications designed for the 223970-1.

Q: What is the difference between the 5223970-1 and 5223963-1?

A: Both parts are mechanically and electrically equivalent. The primary differences are: (1) Contact finish specification – 5223970-1 specifies Gold with defined thickness (50.0µin), while 5223963-1 allows Gold or Gold-Palladium; (2) Packaging – 5223970-1 packaging is not specified, while 5223963-1 is supplied in Tube format; (3) RoHS certification level – 5223970-1 is RoHS Compliant, 5223963-1 is ROHS3 Compliant; (4) Inventory availability – 5223963-1 has higher stock levels (3020 pieces vs. 767 pieces).

Q: Are the operating temperature and voltage ratings the same for all parts?

A: The 223970-1 does not specify operating temperature or voltage ratings in its documentation. Both substitute parts (5223970-1 and 5223963-1) specify identical operating temperature range (-55°C ~ 125°C) and voltage rating (250V). These specifications should be verified against application requirements.

Q: Does the 223970-1 have RoHS compliance?

A: No. The 223970-1 is classified as RoHS non-compliant. Both substitute parts address this requirement: 5223970-1 is RoHS Compliant, and 5223963-1 is ROHS3 Compliant.

Q: What is the significance of the contact finish thickness specification?

A: The 5223970-1 specifies contact finish thickness at 50.0µin (1.27µm), providing defined quality parameters for gold plating. The 223970-1 and 5223963-1 do not specify contact finish thickness. For applications requiring controlled contact resistance or long-term reliability specifications, the 5223970-1 offers enhanced traceability.

Q: Are there any differences in the board guide feature?

A: No. All three parts (223970-1, 5223970-1, and 5223963-1) include the board guide feature as specified in their contact layout and features.

Q: Which part should be selected for new designs?

A: For new designs, either 5223970-1 or 5223963-1 should be selected, as both are active products with current compliance certifications. The 223970-1 is obsolete and should not be specified for new applications.
