Substitute Part Grouping Explanation
Substitution of the TE Connectivity 749767-1 is determined by strict alignment of core electrical and mechanical parameters. All substitute parts must maintain the following critical specifications: 15-position configuration, 3-row high-density D-Sub layout (Shell Size 1, DE/E), right-angle through-hole solder termination, nickel-plated steel shell with gold-plated contacts at 30.0µin thickness, 0.350" backset spacing, 4-40 flange mounting, UL94 V-0 flammability rating, and board lock with grounding indent features.
Substitute parts are classified into two categories based on parameter alignment:
Direct Manufacturer Equivalent (633-015-663-032): Mercury United Electronics part offering identical mechanical and electrical interface compatibility with the main part, differing only in inventory status and series designation.
Parametric Equivalents (K66X-E15P-N30, KF66X-E15P-N30): Kycon, Inc. parts maintaining all critical mechanical parameters and core electrical specifications. These parts are active products with RoHS3 compliance and represent functional alternatives for new designs and legacy system support.
Similar Manufacturer Part (633-015-663-042): Mercury United Electronics variant with enhanced current rating (3A per contact) and additional shielding features, suitable for applications requiring increased current capacity within the same form factor.

Engineering Selection Recommendations
For Direct Replacement in Legacy Systems:
The Mercury United Electronics 633-015-663-032 provides direct mechanical and electrical interface compatibility with the TE Connectivity 749767-1. This part maintains identical connector geometry, pin configuration, and mounting characteristics. Selection of this part is appropriate for systems requiring exact form-factor compatibility without design modification.
For New Designs and Active Product Support:
The Kycon K66X-E15P-N30 and KF66X-E15P-N30 are recommended for new product development and systems requiring long-term component availability. Both parts maintain all critical mechanical parameters and core electrical specifications while offering active product status and RoHS3 compliance. The KF66X-E15P-N30 provides additional RoHS compliance certification. These parts are suitable for applications where compliance certifications and ongoing manufacturer support are required.
For Applications Requiring Enhanced Current Capacity:
The Mercury United Electronics 633-015-663-042 offers increased current rating of 3A per contact compared to the 2A rating of the main part, with identical mechanical interface and additional shielding features. This part is suitable for applications requiring higher current handling within the same connector form factor and mounting configuration.
Compliance Considerations:
The TE Connectivity 749767-1 is RoHS non-compliant. Systems subject to RoHS requirements must transition to the Mercury 633-015-663-042 (ROHS3 Compliant), Kycon K66X-E15P-N30 (ROHS3 Compliant), or Kycon KF66X-E15P-N30 (RoHS Compliant) alternatives.
Temperature and Voltage Operating Ranges:
The main part operates across -55°C to 105°C at 125V. The Kycon alternatives operate across -55°C to 75°C at 29VAC, representing a reduced operating envelope. The Mercury 633-015-663-042 operates across -55°C to 85°C. Applications requiring the full temperature range of the original part should confirm compatibility with the reduced operating range of substitute parts.
Frequently Asked Questions (FAQ)
Q: Can the Mercury 633-015-663-032 be used as a direct replacement for the TE Connectivity 749767-1?
A: The Mercury 633-015-663-032 maintains identical mechanical interface specifications including connector style, pin configuration, shell size, mounting type, and termination method. Direct physical and electrical interface compatibility is established. Verification of specific application requirements is necessary to confirm functional equivalence.
Q: What are the key differences between the Kycon K66X-E15P-N30 and KF66X-E15P-N30?
A: Both parts maintain identical mechanical and electrical specifications. The primary difference is RoHS compliance certification status: K66X-E15P-N30 is ROHS3 Compliant with REACH Affected status, while KF66X-E15P-N30 is RoHS Compliant. Both parts are active products with equivalent current ratings of 1.5A and operating temperature range of -55°C to 75°C.
Q: Why does the Mercury 633-015-663-042 have a higher current rating than the main part?
A: The Mercury 633-015-663-042 is rated for 3A per contact compared to the 2A rating of the TE Connectivity 749767-1. This increased capacity reflects design differences in contact material (Copper Alloy versus Phosphor Bronze) and contact geometry. Applications requiring only 2A operation can utilize this part without derating.
Q: Are the Kycon alternatives suitable for applications requiring 125V operation?
A: The Kycon K66X-E15P-N30 and KF66X-E15P-N30 are rated for 29VAC operation, which differs from the 125V rating of the main part. Applications requiring 125V operation must confirm compatibility with the reduced voltage rating of these alternatives or select the Mercury 633-015-663-042, which does not specify a voltage limitation.
Q: What is the impact of the reduced operating temperature range on substitute part selection?
A: The TE Connectivity 749767-1 operates across -55°C to 105°C. The Kycon alternatives operate across -55°C to 75°C, and the Mercury 633-015-663-042 operates across -55°C to 85°C. Applications requiring operation above 85°C must confirm compatibility with the reduced upper temperature limit or select alternative components.
Q: Are all substitute parts available in the same packaging configuration?
A: The TE Connectivity 749767-1 packaging is not specified. The Mercury 633-015-663-032 packaging is not specified. The Mercury 633-015-663-042, Kycon K66X-E15P-N30, and Kycon KF66X-E15P-N30 are supplied in Tray packaging. Packaging configuration differences may affect procurement and handling procedures.
Q: Which substitute part is recommended for RoHS-compliant applications?
A: The Mercury 633-015-663-042 is ROHS3 Compliant, the Kycon K66X-E15P-N30 is ROHS3 Compliant, and the Kycon KF66X-E15P-N30 is RoHS Compliant. All three parts satisfy RoHS compliance requirements. The TE Connectivity 749767-1 is RoHS non-compliant and cannot be used in applications subject to RoHS regulations.
Q: What is the significance of the contact material differences among substitute parts?
A: The TE Connectivity 749767-1 uses Phosphor Bronze contacts. The Mercury 633-015-663-032 contact material is not specified. The Mercury 633-015-663-042 uses Copper Alloy contacts. The Kycon K66X-E15P-N30 and KF66X-E15P-N30 use Brass contacts. Contact material affects electrical conductivity, corrosion resistance, and mechanical durability. All specified materials are suitable for signal-level applications in the D-Sub connector category.
Q: Can the Mercury 633-015-663-042 be used in applications requiring board edge mounting?
A: The Mercury 633-015-663-042 supports Board Edge, Through Hole, and Right Angle mounting types, providing additional mounting flexibility compared to the TE Connectivity 749767-1, which supports only Through Hole and Right Angle mounting. This part is suitable for applications requiring board edge mounting capability.
