Key Parameters

Substitute Part Grouping Explanation

The Molex 0452802202 can be substituted with the Molex 0452802252 based on the following critical parameters that remain identical between both parts:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (22 positions, 2 rows)
• Mating pitch and row spacing (0.118" / 3.00mm)
• Mounting method and shrouding design (Through Hole, Shrouded - 4 Wall)
• Termination and fastening specifications (Press-Fit, Solder; Push-Pull)
• Insulation material, height, and color (Polyamide/Nylon Glass Filled, 0.457", Black)
• Contact shape and material (Square, Copper Alloy)
• Mating contact finish (Gold)
• Flammability rating (UL94 V-0)
• Applicable industries (General Purpose, Medical, Military, Telecommunications)

The substitute part differs only in product status (Active vs. Obsolete), packaging format (Tray vs. unspecified), post contact finish composition (Tin vs. Tin-Lead), and post contact finish thickness (10.0µin vs. 100.0µin), along with RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452802252 is the direct substitute for the obsolete Molex 0452802202. Both connectors maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-to-board and cable applications.

The primary advantage of selecting the 0452802252 is its active product status, ensuring ongoing availability and manufacturing support. Additionally, the 0452802252 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations in medical, military, and telecommunications sectors.

The post contact finish differs between the two parts: the original uses Tin-Lead with 100.0µin thickness, while the substitute uses Tin with 10.0µin thickness. Both finishes are suitable for solder termination applications. The packaging format for the substitute is specified as Tray, which may affect procurement and handling procedures compared to the original part.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0452802202 and 0452802252 mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch specifications (0.118" / 3.00mm), row configuration (2 rows, 22 positions), mounting type (Through Hole), and shrouding design (Shrouded - 4 Wall). They are mechanically interchangeable in all board-to-board and cable applications.

Q: What is the primary reason to substitute the 0452802202 with the 0452802252?

A: The 0452802202 is classified as obsolete, while the 0452802252 maintains active product status. This ensures continued component availability, manufacturing support, and compliance with current regulatory standards.

Q: Does the post contact finish difference affect solderability?

A: Both Tin-Lead and Tin finishes are suitable for solder termination. The difference in finish thickness (100.0µin vs. 10.0µin) does not impact the fundamental solderability or electrical performance of the connector in standard through-hole assembly processes.

Q: Is the 0452802252 suitable for medical and military applications?

A: Yes. The 0452802252 is specified for General Purpose, Medical, Military, and Telecommunications applications. It maintains the UL94 V-0 flammability rating and REACH Unaffected status required for these sectors.

Q: What is the significance of the RoHS compliance difference?

A: The 0452802252 is ROHS3 compliant, while the 0452802202 is RoHS non-compliant. For applications subject to RoHS regulations, the 0452802252 is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

Q: Does packaging format affect component performance?

A: No. The packaging format (Tray for the 0452802252) affects procurement, storage, and handling procedures but does not impact electrical or mechanical performance. Both parts maintain identical MSL ratings (1 - Unlimited).
