Substitute Part Grouping Explanation

Substitute parts for the Molex 0022552521 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

• Identical connector type (Receptacle)
• Identical contact type (Female Socket)
• Identical number of positions (52)
• Identical pitch specification (0.100" / 2.54mm)
• Identical row configuration (2 rows with 0.100" spacing)
• Identical mounting type (Free Hanging In-Line)
• Identical contact termination method (Crimp)
• Identical insulation material (Polyester, Glass Filled)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical color (Black)
• Equivalent compliance status (RoHS3, REACH Unaffected)

The Molex 0022566527 meets all these criteria and is classified as a parametric equivalent within the SL 70450 series family.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0022552521 and 0022566527 are Active products with full RoHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for current and future applications. Selection between these parts should be based on inventory availability and supply chain considerations rather than technical performance, as they are parametrically identical across all electrical and mechanical specifications.

The 0022566527 currently maintains higher inventory levels (1332 pcs vs. 786 pcs), which may provide supply chain advantages for high-volume production requirements. Both parts are suitable for direct substitution in existing designs without modification to PCB layouts, mating connectors, or contact specifications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. The 0022552521 and 0022566527 are parametrically identical in all electrical specifications, including contact type, pitch, number of positions, and operating temperature range.

Q: Can I substitute one part for the other on my PCB? A: Yes. Both parts are mechanically identical with the same mounting type, row configuration, and physical dimensions. No PCB redesign is required.

Q: What is the difference between these two part numbers? A: The parts are functionally equivalent. The difference lies in their base product numbers (002255 vs. 002256) and current inventory levels. Both belong to the same SL 70450 series.

Q: Do these housings include contacts? A: No. Both parts are housings only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.

Q: Are both parts RoHS compliant? A: Yes. Both the 0022552521 and 0022566527 are RoHS3 compliant with MSL rating of 1 (Unlimited), suitable for standard storage and handling conditions.

Q: What is the operating temperature range? A: Both parts operate across -40°C to 105°C, suitable for industrial and commercial applications.
