Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 796697-7 is determined by the following critical parameters: 7-position configuration, vertical through-hole mounting, solder termination, and compliance with UL94 V-0 flammability rating. The primary substitution criterion is pitch tolerance, as the 0.197" (5.00mm) pitch specification defines mechanical and electrical compatibility with mating connectors.

Direct Equivalent (Pitch-Matched):

• TE Connectivity 1776138-7: Identical pitch (5.00mm), same position count, active product status, RoHS compliant
• Phoenix Contact 1753534: Identical pitch (5.00mm), same position count, active product status, ROHS3 compliant

Functional Equivalent (Pitch Variation):

• Amphenol PCD ELFH07250: Pitch of 0.200" (5.08mm) represents a 0.08mm deviation from the main part specification, classified as a functional equivalent with potential mechanical compatibility considerations

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1776138-7

The TE Connectivity 1776138-7 is the preferred direct substitute for the obsolete 796697-7. Both parts share identical electrical and mechanical specifications: 7-position configuration, 0.197" (5.00mm) pitch, vertical through-hole mounting, 15 A (UL) current rating, and 300 V (UL) voltage rating. The 1776138-7 maintains the same operating temperature range (-40°C to 110°C) and UL94 V-0 flammability rating. The substitute is active in production status and RoHS compliant, supporting modern procurement and regulatory requirements. The primary distinction is housing color (black versus blue) and the addition of side stacking features.

Secondary Substitute: Phoenix Contact 1753534

The Phoenix Contact 1753534 provides functional equivalence with identical pitch (5.00mm) and position count. This part operates at 12 A (UL) and 300 V (UL), representing a 3 A reduction in current capacity compared to the main part. The 1753534 is active in production and ROHS3 compliant. The operating temperature range is not specified in available documentation. Selection of this substitute requires confirmation that the 12 A current rating satisfies circuit requirements.

Functional Equivalent: Amphenol PCD ELFH07250

The Amphenol PCD ELFH07250 operates at 0.200" (5.08mm) pitch, representing a 0.08mm deviation from the 0.197" (5.00mm) specification. This part maintains 15 A (UL) and 300 V (UL) ratings with UL94 V-0 flammability compliance. The insulation height is 0.319" (8.10mm), compared to 0.472" (12.00mm) for the main part, indicating reduced shrouding height. The ELFH07250 features 4-side shrouding versus 2-side shrouding on the main part. This substitute is active in production and RoHS compliant. Mechanical compatibility with existing mating connectors requires verification due to pitch variation and shrouding differences.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1776138-7 be used as a direct replacement for the 796697-7?

A: Yes. The 1776138-7 is a direct electrical and mechanical equivalent with identical pitch (5.00mm), position count (7), current rating (15 A UL), voltage rating (300 V UL), and operating temperature range (-40°C to 110°C). Both parts feature UL94 V-0 flammability rating and tin contact mating finish. The primary difference is housing color and the addition of side stacking features on the 1776138-7.

Q: What is the significance of the pitch specification in terminal block selection?

A: Pitch defines the center-to-center distance between adjacent positions and determines mechanical compatibility with mating connectors and PCB footprints. The 0.197" (5.00mm) pitch of the main part and direct substitutes (1776138-7 and 1753534) ensures compatibility with existing designs. The Amphenol PCD ELFH07250 operates at 0.200" (5.08mm) pitch, which may introduce mechanical incompatibility with existing mating connectors designed for 5.00mm spacing.

Q: Does the Phoenix Contact 1753534 meet the current requirements of the original design?

A: The 1753534 is rated for 12 A (UL), compared to 15 A (UL) for the main part. Selection of this substitute requires confirmation that the circuit operates within the 12 A limit. If the design requires 15 A capacity, the 1753534 is not suitable.

Q: What is the difference between 2-side and 4-side shrouding?

A: Shrouding refers to the protective housing surrounding the connector positions. The main part (796697-7) and direct substitutes (1776138-7 and 1753534) feature 2-side shrouding. The Amphenol PCD ELFH07250 features 4-side shrouding, providing additional protection on all sides. This difference may affect mechanical fit in existing designs and should be evaluated against PCB layout constraints.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 1776138-7 is RoHS compliant. The Phoenix Contact 1753534 is ROHS3 compliant. The Amphenol PCD ELFH07250 is RoHS compliant. The original 796697-7 has RoHS status listed as "Not applicable." All active substitutes meet current RoHS requirements.

Q: What is the difference in insulation height between the main part and substitutes?

A: The main part (796697-7) and direct substitutes (1776138-7 and 1753534) feature 0.472" (12.00mm) insulation height. The Amphenol PCD ELFH07250 features 0.319" (8.10mm) insulation height, representing a 0.153" reduction. This difference affects the overall profile of the connector and may impact PCB clearance and mechanical fit.

Q: Can the Amphenol PCD ELFH07250 be used in applications requiring the original 5.00mm pitch?

A: The ELFH07250 operates at 0.200" (5.08mm) pitch, which differs from the 0.197" (5.00mm) specification. Compatibility depends on the tolerance specifications of mating connectors and PCB footprints. A 0.08mm pitch deviation may exceed acceptable tolerances in precision applications. Mechanical compatibility must be verified before selection.

Q: What is the contact tail length specification, and why does it matter?

A: Contact tail length defines the length of the solder tail extending from the connector housing. The main part specifies 0.138" (3.50mm). The TE Connectivity 1776138-7 and Phoenix Contact 1753534 maintain this specification. The Amphenol PCD ELFH07250 does not specify contact tail length in available documentation. This parameter affects solder joint formation and PCB hole sizing.
