Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794310-1 connector is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

Electrical Parameters: Voltage rating of 600VAC, operating temperature range of -55°C to 105°C, and contact material composition (copper alloy).

Mechanical Parameters: 18 positions in 2-row configuration, 0.165" (4.20mm) mating pitch, 0.165" (4.20mm) row spacing, square contact shape, through-hole solder termination, shrouded 4-wall construction, and locking ramp fastening type.

Physical Dimensions: 0.504" (12.80mm) insulation height, 0.138" (3.50mm) contact post length, and natural insulation color.

Material & Compliance: Polyamide (PA) nylon insulation, UL94 V-2 flammability rating, and MSL 1 moisture sensitivity level.

The substitute part 1-794310-1 meets all these criteria with the exception of contact finish composition, which transitions from tin-lead to tin, and product status, which changes from obsolete to active. These differences do not affect functional compatibility or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-794310-1 is the direct active equivalent of the obsolete 794310-1 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status: The original 794310-1 is classified as obsolete, while the substitute 1-794310-1 maintains active product status with confirmed inventory availability (1050 pieces in stock). This ensures continued supply chain access for production and maintenance applications.

Regulatory Compliance: The substitute part 1-794310-1 achieves RoHS compliance and REACH unaffected status, compared to the non-compliant status of the original part. This improvement aligns with current environmental and regulatory requirements for electronic component procurement.

Contact Finish Specification: The transition from tin-lead to tin contact finish in the substitute part reflects industry-wide compliance with lead-free manufacturing standards. Both finishes maintain identical thickness specifications (118.1µin / 3.00µm) and are functionally compatible for solder termination applications.

Functional Equivalence: All critical electrical and mechanical parameters remain unchanged between the original and substitute parts. The 18-position, 2-row configuration with 0.165" (4.20mm) pitch, through-hole solder termination, shrouded 4-wall construction, and locking ramp fastening provide identical performance characteristics and mechanical interchangeability.

Application Continuity: The substitute part maintains the same operating temperature range (-55°C to 105°C), voltage rating (600VAC), flammability rating (UL94 V-2), and moisture sensitivity level (MSL 1), ensuring compatibility with existing circuit board designs and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the substitute part 1-794310-1 be used as a direct replacement for the obsolete 794310-1?

A: Yes. The substitute part 1-794310-1 is a direct functional and mechanical equivalent. All critical parameters including connector type, position count, pitch, mounting method, termination type, and operating specifications are identical. The parts are interchangeable in circuit board designs and applications.

Q: What is the difference between the tin-lead finish of the original part and the tin finish of the substitute?

A: The original 794310-1 uses tin-lead contact finish, while the substitute 1-794310-1 uses tin finish. Both maintain the same thickness specification of 118.1µin (3.00µm). The tin finish reflects current lead-free manufacturing standards and is functionally compatible with solder termination processes.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The substitute part 1-794310-1 is RoHS compliant and REACH unaffected, compared to the non-compliant status of the original 794310-1. This provides improved alignment with current environmental and regulatory standards for electronic component procurement.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts maintain identical physical dimensions including 0.504" (12.80mm) insulation height, 0.138" (3.50mm) contact post length, 0.165" (4.20mm) mating pitch, and 0.165" (4.20mm) row spacing. The parts are mechanically interchangeable on circuit boards designed for the original connector.

Q: What is the inventory status of the substitute part?

A: The substitute part 1-794310-1 has 1050 pieces in stock as new original inventory, ensuring availability for production and repair applications. The original 794310-1 has 908 pieces available but is classified as obsolete.

Q: Are there any temperature or voltage limitations when using the substitute part?

A: No. The substitute part 1-794310-1 maintains the same operating temperature range of -55°C to 105°C and voltage rating of 600VAC as the original part. There are no additional limitations or derating requirements.

Q: What mounting and termination methods are used for this connector?

A: Both the original and substitute parts use through-hole mounting with solder termination. The connectors feature a locking ramp fastening type and shrouded 4-wall construction for board-to-board or cable applications.

Q: Is the substitute part available from the same manufacturer?

A: Yes. Both the original 794310-1 and substitute 1-794310-1 are manufactured by TE Connectivity AMP Connectors and belong to the AMP-DUAC series. The substitute represents the current active production equivalent.
