Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1734827-7 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 7
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Shape: Square
• Operating Temperature Range: -25°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The JST Sales America Inc. S7B-PH-SM4-TB satisfies all mandatory matching parameters and qualifies as a direct substitute. The substitute part maintains identical mechanical and electrical interface characteristics while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The JST Sales America Inc. S7B-PH-SM4-TB is a qualified substitute for the obsolete TE Connectivity 1734827-7 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. The original part is classified as obsolete, making substitution necessary for new designs and ongoing production.

Compliance and Certifications: The substitute part holds ROHS3 compliance certification, providing enhanced environmental and regulatory alignment compared to the original part's undefined RoHS status. Both parts maintain UL94 V-0 flammability rating and identical moisture sensitivity classification.

Electrical and Mechanical Interface: All critical interface parameters align precisely between the two parts, including pitch, position count, mounting configuration, and shrouding design. The substitute part's increased current rating of 2A provides additional design margin over the original 1A specification.

Material Considerations: The substitute part utilizes copper alloy contacts and PA6T insulation material, which differ from the original brass contacts and PA9T insulation. These material variations remain within acceptable substitution parameters for the rectangular connector category and do not compromise functional compatibility.

Voltage Rating Differential: The substitute part specifies 100V voltage rating compared to the original 125V rating. Applications operating at or below 100V voltage levels are fully compatible. Applications requiring voltage ratings above 100V require alternative substitute evaluation.

Frequently Asked Questions (FAQ)

Q: Can the JST S7B-PH-SM4-TB directly replace the TE Connectivity 1734827-7 in existing designs?

A: Yes, for applications operating at voltage levels of 100V or below. The substitute part maintains identical mechanical and electrical interface characteristics, including pitch, position count, mounting type, and shrouding configuration. The substitute part's 2A current rating exceeds the original 1A specification, providing additional design margin.

Q: What is the significance of the voltage rating difference between the two parts?

A: The original part specifies 125V maximum voltage rating, while the substitute part specifies 100V. Applications designed for operation at 100V or below are fully compatible with the substitute part. Applications requiring voltage ratings above 100V must identify alternative substitute parts that maintain the 125V specification.

Q: How do the contact material differences affect substitution?

A: The original part uses brass contacts while the substitute part uses copper alloy contacts. Both materials provide adequate electrical conductivity and contact reliability for the 2.00mm pitch rectangular connector category. The material difference does not compromise functional compatibility or electrical performance within the specified operating parameters.

Q: What is the impact of insulation material differences?

A: The original part uses PA9T (Nylon 9T, glass-filled) insulation while the substitute part uses PA6T (Nylon 6T) insulation. Both materials meet UL94 V-0 flammability requirements and maintain identical operating temperature ranges of -25°C to 85°C. The insulation material difference does not affect mechanical or electrical compatibility.

Q: Does the substitute part's Tape & Reel packaging affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The Tape & Reel packaging of the substitute part provides advantages for automated assembly processes. Component-level functionality remains identical regardless of packaging configuration.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation decisions. The TE Connectivity 1734827-7 has been discontinued, necessitating identification of active equivalent parts for ongoing design and procurement requirements. The JST S7B-PH-SM4-TB maintains active product status and provides long-term supply availability.

Q: Are there any application restrictions for the substitute part?

A: The substitute part is suitable for applications operating at 100V or below. Applications requiring voltage ratings above 100V require alternative substitute evaluation. All other electrical and mechanical parameters align with the original part specifications, permitting direct substitution within voltage constraints.

Q: What compliance advantages does the substitute part offer?

A: The substitute part holds ROHS3 compliance certification, providing enhanced environmental and regulatory alignment. Both parts maintain UL94 V-0 flammability rating and identical moisture sensitivity classification (MSL 1 - Unlimited), ensuring compliance with industrial and medical application requirements.
