Key Parameters

Substitute Part Grouping Explanation

The M52-5052545 is identified as a manufacturer-recommended substitute for the M52-5052245. Substitution eligibility is determined by the following critical parameters:

• Connector Type: Both are receptacle connectors
• Contact Type: Both feature female socket contacts
• Pitch - Mating: Both maintain 0.050" (1.27mm) pitch
• Mounting Type: Both are surface mount
• Termination: Both use solder termination
• Contact Finish - Mating: Both have gold plating
• Operating Temperature Range: Both operate -40°C ~ 105°C
• Current Rating: Both rated at 1A
• Material Flammability Rating: Both meet UL94 V-0
• Insulation Material: Both use Polyamide (PA6T), Nylon 6T
• Contact Material: Both use Phosphor Bronze
• RoHS Status: Both are ROHS3 Compliant

The primary difference is the number of positions: M52-5052245 provides 22 positions, while M52-5052545 provides 25 positions. This difference requires circuit design evaluation to determine compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M52-5052545 is an active product from the same manufacturer with identical electrical and mechanical specifications to the M52-5052245, with the exception of position count. Selection of the substitute requires evaluation of circuit requirements:

• If the application requires exactly 22 positions, the M52-5052545 with 25 positions may require circuit redesign or selective population of connector positions.
• The M52-5052545 maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory continuity.
• Both connectors share identical thermal operating ranges, current ratings, and material specifications, supporting direct functional replacement in applications where position count flexibility exists.
• The active product status of M52-5052545 ensures ongoing availability and supply chain stability compared to the obsolete M52-5052245.

Frequently Asked Questions (FAQ)

Q: Can the M52-5052545 directly replace the M52-5052245 in existing designs?

A: Direct replacement is possible only if the circuit design can accommodate the additional 3 positions (25 vs. 22). All electrical and mechanical parameters are identical. PCB layout modifications may be required.

Q: What is the primary reason for substitution?

A: The M52-5052245 is obsolete. The M52-5052545 is an active product from the same manufacturer with equivalent specifications, ensuring continued availability and supply chain support.

Q: Are there any compliance differences between these connectors?

A: No. Both connectors are ROHS3 Compliant, REACH Unaffected, and meet UL94 V-0 flammability requirements. Regulatory compliance is maintained with substitution.

Q: What are the mating pitch specifications for both connectors?

A: Both connectors maintain a 0.050" (1.27mm) mating pitch, ensuring compatibility with corresponding plug connectors designed for this pitch standard.

Q: Are thermal operating ranges identical?

A: Yes. Both connectors operate across the identical temperature range of -40°C to 105°C, supporting equivalent thermal performance in target applications.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
