Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1634225-2 is determined by strict equivalence in the following core parameters:

Critical Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 37
• Number of rows: 2
• Shell size and connector layout: 4 (DC, C)
• Mounting type: Through Hole
• Termination method: Solder
• Shell material and finish: Steel, Nickel Plated
• Contact finish: Gold
• Current rating: 3A per contact
• Material flammability rating: UL94 V-0

The three Mercury United Electronics, Inc. substitute parts (628-037-228-042, 628-037-220-042, and 628-037-220-047) satisfy all critical matching parameters. These parts are active products with current manufacturing status, providing viable alternatives to the obsolete TE Connectivity component. Variations in contact material (Brass vs. Phosphor Bronze), dielectric material composition, flange feature configuration (Board Side vs. Housing/Shell), and operating temperature upper limits represent acceptable engineering trade-offs within the D-Sub receptacle category while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1-1634225-2 is classified as obsolete. All three Mercury United Electronics substitute parts (628-037-228-042, 628-037-220-042, and 628-037-220-047) maintain active product status with current manufacturing availability, ensuring long-term supply chain viability.

Compliance and Certification: The TE Connectivity original part is RoHS non-compliant. All three Mercury substitute parts are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution. All parts maintain UL94 V-0 material flammability certification and EAR99 export classification.

Functional Equivalence: All substitute parts maintain the critical electrical and mechanical parameters: 37-position D-Sub receptacle configuration, 2-row layout, shell size 4 (DC, C), through-hole solder termination, 3A current rating per contact, and UL94 V-0 flammability rating. The operating temperature upper limit for Mercury parts is 85°C compared to 105°C for the original TE Connectivity part; applications requiring operation above 85°C require evaluation against specific thermal requirements.

Part-Specific Selection:

• 628-037-228-042: Supports both signal and power contacts; includes shielding feature
• 628-037-220-042: Signal contact configuration; includes shielding feature
• 628-037-220-047: Signal contact configuration; includes both shielding and board lock features

Selection among the three Mercury alternatives depends on specific application requirements for contact type (signal vs. signal/power), shielding necessity, and board lock functionality.

Frequently Asked Questions (FAQ)

Q: Can Mercury 628-037-220-042 directly replace TE Connectivity 1-1634225-2?

A: Yes. Both connectors share identical core specifications: 37-position D-Sub receptacle, 2-row configuration, shell size 4 (DC, C), through-hole solder termination, steel nickel-plated shell, gold-plated contacts, 3A current rating, and UL94 V-0 flammability rating. The Mercury part is an active product with ROHS3 compliance, addressing the obsolescence of the TE Connectivity component.

Q: What is the difference between Mercury 628-037-228-042 and 628-037-220-042?

A: The primary difference is contact type. Part 628-037-228-042 supports both signal and power contacts, while 628-037-220-042 is configured for signal contacts only. Both include shielding and maintain identical electrical and mechanical specifications otherwise.

Q: Does Mercury 628-037-220-047 include board lock functionality?

A: Yes. Mercury 628-037-220-047 includes both board lock and shielding features, distinguishing it from 628-037-220-042, which includes shielding only. Both maintain identical electrical specifications and 37-position D-Sub receptacle configuration.

Q: What is the significance of the operating temperature difference between the original and substitute parts?

A: The TE Connectivity original part operates from -55°C to 105°C, while all Mercury substitutes operate from -55°C to 85°C. Applications requiring sustained operation above 85°C must evaluate whether this reduced upper temperature limit affects system performance or reliability requirements.

Q: Are all substitute parts available in the same packaging format?

A: The TE Connectivity original part packaging is not specified in the provided data. All three Mercury substitute parts are supplied in Tray packaging. Packaging compatibility with existing assembly processes should be verified during component procurement.

Q: What is the difference between contact finish thickness specifications?

A: The TE Connectivity original part specifies 15.0µin (0.38µm) gold plating thickness. All Mercury substitute parts specify Flash gold plating, which is a thinner, economical plating process. Both finishes provide adequate contact protection and conductivity for the specified 3A current rating and 250V voltage application.

Q: Are the substitute parts REACH compliant?

A: The TE Connectivity original part is REACH Affected. All three Mercury substitute parts are REACH Unaffected, indicating compliance with REACH regulatory requirements for substance restrictions in electrical components.
